This national report of Japan, submitted in accordance with the provisions of Article 32 of “the Joint
Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste
Management”, addresses the measures taken to implement each of the obligations of the Convention.
The text (Sections B through K) and the annexes (Section L) of the report are prepared in accordancewith “the Guidelines regarding the Form and Structure of National Reports”, and the text of each
Article of the Convention is reproduced in bold letters at the top of the report on the Article.
This report was prepared by the Nuclear and Industrial Safety Agency (NISA) of the Ministry of
Economy, Trade and Industry (METI), the Science and Technology Policy Bureau (STPB) of the
Ministry of Education, Culture, Sports, Science and Technology (MEXT), and the Pharmaceutical andFood Safety Bureau (PFSB) and Health Policy Bureau (HPB) of the Ministry of Health, Labour andWelfare (MHLW), in consultation with other relevant governmental organizations, and was reported
to the Nuclear Safety Commission (hereinafter called the NSC). In preparing the report, cooperation
was obtained from the Japan Nuclear Energy Safety Organization (JNES) and other relevantorganizations. The report was also reviewed by the Nuclear and Industrial Safety Subcommittee of theAdvisory Committee for Natural Resources and Energy of METI.

In this report, following issues are taken into consideration. Some items for which it wasrecommended by the summary report of the first review meeting to provide further information in thenext review meeting, and questions and comments on our previous report raised by other Contracting
Parties during the first review meeting.

A. 2
(1)

Current Status of Utilization of Nuclear Energy and its Management

Current Status of Utilization of Nuclear Energy
In Japan, 40 years have passed since research, development and utilization of nuclear energy
began, and various activities are presently ongoing. Outline of the current status as of March 2005
is as follows.
Operation of the first commercial nuclear power reactor in Japan started in 1966. Following the1973 oil crisis, nuclear power plants were built actively, and now a total of 56 commercial nuclear
power reactors are in operation. One reactor is at the decommissioning stage. Nuclear fuel cycle
facilities related to commercial power generation, including 2 enrichment facilities, 4 fuelmanufacturing facilities, 2 reprocessing facilities, 2 disposal facilities are in operation or underconstruction. In addition, sixteen research reactors are in operation at national and private
institutes and universities.
A-1

Various forms of utilization of radiation are now widely applied in research applications, inmedical diagnosis and treatment and in commercial activities. There are more than 5000 nationalor private facilities utilizing various types of radiation.
(2)

Basic Policy of Utilization of Nuclear Energy and Current Status of its Management
The research, development and utilization of nuclear energy in Japan are conducted solely forpeaceful purposes in accordance with the Atomic Energy Basic Law. The Atomic Energy
Commission (AEC), established on the basis of the law, plans, deliberates and makes decisions on
national policies relating to the utilization of nuclear energy for peaceful purposes. In order toclarify the fundamentals for the utilization of nuclear energy and its development, the Commission
has formulated a total of nine Long-Term Programs for Research, Development and Utilization of
Nuclear Energy (Long-Term Programs) since 1956, one approximately every five years. The newprogram is being prepared and will be published by the end of 2005. Based on the policy stated in
the Long-Term Program, the Agency for Natural Resources and Energy (ANRE) of METI and
MEXT establish implementation plans for utilization of nuclear energy for power generation andrelated fuel cycle activities, and implementation plans for utilization of nuclear energy in scienceand technology and radioisotopes, respectively.
Fundamental laws to ensure safety in the utilization of nuclear energy and radiation are the Law
for the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors (the Reactor
Regulation Law) and the Law Concerning Prevention from Radiation Hazards due toRadioisotopes, etc. (the Radiation Hazards Prevention Law), both of which are based on the
Atomic Energy Basic Law, and the Medical Care Law, the Pharmaceutical Affairs Law and theClinical Laboratory Technicians and Health Laboratory Technicians Law (the latter three arereferred to hereafter as the Medical Care Law, etc.). These laws and their related regulations havebeen amended, as appropriate, as the utilization of nuclear energy and radiation expands anddiversifies. The laws are consistent among them in terms of the basics and details of radiation
protection. The NSC, established on the basis of the Atomic Energy Basic Law, plans, deliberates
and makes decisions on policies aimed at ensuring the safe utilization of nuclear energy. As theregulatory bodies responsible for ensuring safety within their particular area of competence, NISA
of METI, the STPB of MEXT and the PFSB and the HPB of the MHLW regulate and issue
guidance on relevant activities. Operators of nuclear facilities conduct their activities under thepolicies and the regulations mentioned above.
Important progresses from previous report on nuclear safety regulations are as follows. The
Reactor Regulation Law and the relevant regulation were amended in October 2003. License
holders are obliged to include their Quality Assurance Programs in the Operational Safety
Programs and obtain approval from the regulatory body. The Electric Utilities Industry Law wasamended to provide for the Periodical Licensee’s Inspection and the Periodical Safety
Management Inspection in addition to the ongoing Periodical Inspection. Also, Japan Nuclear
Energy Safety Organization, a technical support organization to NISA, was founded in October
2003. In April 2004, NISA established the Nuclear Safety Public Relations and Training Division
within NISA and assigned the Regional Public Relations Officer for Nuclear Safety, in order topromote public relations. In Other General Safety Provisions in this report, infrastructures ofhuman resources and financial resources, framework of quality assurance and confirmation ofquality assurance by the regulatory body, and regulatory procedure on decommissioning areemphasized.

(3)

Current Status of Spent Fuel Management
As the regulatory authority within their respective areas of competence, NISA of METI and the
STPB of MEXT regulate, and issue guidance on activities aimed at ensuring the safety of spent
fuel management at reactor facilities and spent fuel reprocessing plants, based on the Reactor
Regulation Law and/or the Electricity Utilities Industry Law.
A-2

Basic policy of Japan in this field is to reprocess spent fuel and make effective use of therecovered uranium, plutonium and other usable elements. Spent fuel generated in nuclear powerreactors is sent for reprocessing after a period of on-site storage. Until now, the spent fuel, with the
exception of a portion reprocessed by the Tokai Reprocessing Plant of the Japan Nuclear Cycle
Development Institute (JNC), has been reprocessed in overseas facilities. In the meantime, Japan
Nuclear Fuel Ltd. (JNFL) is constructing the Rokkasho-mura Spent Fuel Reprocessing Plant,
which will start operation in 2007. Storage of spent fuel in the storage facility in the plant has
started since 1999.
Interim storage of spent fuel before reprocessing allows flexibility in the process of nuclear fuelcycle. The Reactor Regulation Law was amended in 1999 to incorporate provisions on interim
spent fuel storage, and a company is preparing for commercial operation of interim storage
facilities by 2010.
(4)

Current Status of Radioactive Waste Management
Based on the Reactor Regulation Law and/or Electricity Utilities Industry Law, NISA of METI
regulates, and issues guidance on facility and activities ensuring the safety of radioactive waste
management in repositories, power reactors, uranium enrichment facilities, fuel manufacturing
facilities and reprocessing facilities. In each nuclear facility and activity, according to the grade ofimportance of safety, criteria and guidance are established for each facility to regulate each stageof licensing design, construction, operation and decommissioning, including emergency
preparedness.
Based on the Reactor Regulation Law, the STPB of MEXT regulates, and issues guidance on
activities to ensure the safety of radioactive waste management in research reactors and fuelmaterial use for research and development purposes, and establishes regulations according to thecharacteristics and scale of each facility.
The STPB, on the basis of the Radiation Hazards Prevention Law, regulates, and issues guidanceon activities of radioactive waste management to ensure the safety of facilities using radioisotopes.
The PFSB and the HPB of the MHLW regulate, and issue guidance on activities of radioactive
waste management facility to ensure the safe management of radioactive wastes produced in
medical applications, based on the Medical Care Law, etc.
The basic policy on the radioactive waste management is that the current generations, who receive
the benefit of nuclear energy, should bear the responsibility to manage the resulting waste
generated in the research, development and utilization of nuclear energy, and should makecontinued efforts at promoting radioactive waste disposal. The operator of the facility that
produces waste has the primary responsibility for safe processing and disposal of the waste, andbased on the principle, they prepare and implement their plans with consultation of other relevantorganizations. Meanwhile, the government regulates, and issues guidance to, the producers,
ensuring that waste processing and disposal are carried out appropriately and safely.
Radioactive waste is classified into two categories. One is high-level waste (HLW) generated fromspent fuel reprocessing, and the other is low-level waste (LLW). The LLW is sub-classified
according to origin (radionuclide composition) and level of radioactivity. The AEC decides on thebasic policy for disposal of radioactive waste. Based on the classification, the NSC decides
fundamental concept for safety regulations on radioactive waste disposal, upper bound ofradioactivity concentration in disposal and the guidance on safety assessment of radioactive waste
disposal facilities. METI and MEXT establish relevant regulations.
LLW generated in reactors, reprocessing facilities, etc., is processed and temporarily stored instorage facility in these facilities and then sent to disposal facility. LLWs below the upper boundlevel from power reactors are being transferred to the waste disposal facility of Japan Nuclear Fuel
A-3

Ltd. for disposal. Concerning other LLW from power reactors which are in storage, relevant safety
criteria on disposal are being prepared. Disposal of very low-level concrete waste fromdismantling of the Japan Power Demonstration Reactor (JPDR) was completed and the disposal
facility was closed in 1997. Reactor of the Tokai Power Station of the Japan Atomic Power Co.
ceased operation in 1998 and has been in decommissioning stage since December 2001.
The Reactor Regulation Law was amended in May 2005 to provide for clearance, and relevant
regulations are being established based on IAEA safety standard.
The Specified Radioactive Waste Final Disposal Act, enacted in the year 2000, provides for an
implementing organization for disposal of the HLW generated from spent fuel reprocessing,financial resource reserved for the disposal, the procedure for selecting disposal sites, etc. In theyear 2000, based on the law, Nuclear Waste Management Organization of Japan was established.
In 2002, the organization started open solicitation for candidate site as the Preliminary
Investigation Areas, which is the first step to select geological disposal site.

A. 3

International Activities

Grounded on the basic policy of Japan, research, development and utilization of nuclear energy should
be conducted solely for peaceful purposes. The government of Japan actively contributed to theestablishment of the International Atomic Energy Agency (IAEA) and has participated in its various
conferences and committees, appropriately taking the results of deliberations into its national policy
making and planning on utilization of nuclear energy. Recognizing that international cooperation isessential in ensuring safety of spent fuel and radioactive waste management, Japan has taken part in
activities of the IAEA and OECD/NEA. NISA hosted the Tokyo conference organized by IAEA in
October 2005 on the safety of radioactive waste management.

A. 4

Facilities to be Reported under the Legal Framework

Under the legal framework of Japan, the facilities related to various nuclear activities, each of which
has to be classified and to be licensed by the Reactor Regulation Law or the Radiation Hazards
Prevention Law. The basic concept of regulations is common among all facilities and activities of eachclassification. In this report, discussions related to the common concept are described, being
supplemented as necessary with additional observations referring to any particular facilities, thus
avoiding unnecessary duplication.
As mentioned in Section E later, the description on the Medical Care Law, etc. is omitted in and after
Section F, since content of the regulation is similar to that of the Radiation Hazards Prevention Law.
The word "processing" in this report is used as meaning of "any operation that changes thecharacteristics of waste, in the process of pretreatment, treatment and conditioning".

B. Policies and Practices

Blank Page

B. Policies and Practices (Article 32, Section 1)
1. In accordance with the provisions of Article 30, each Contracting Party shall submit anational report to each review meeting of Contracting Parties. This report shall address
the measures taken to implement each of the obligations of the Convention. For eachContracting Party the report shall also address its:(i) spent fuel management policy;(ii) spent fuel management practices;(iii) radioactive waste management policy;(iv) radioactive waste management practices;(v) criteria used to define and categorize radioactive waste.

As introduced in Section A, the AEC has formulated a series of Long-Term Programs. According to
the policy stated in the latest Long-Term Program (The Program), the ANRE of METI establishes
implementation plans for utilizing nuclear energy for power generation and fuel cycle activities, andMEXT establishes implementation plans for scientific and technological applications of nuclear power
and utilization of radioisotopes, respectively. Moreover, the NSC plans, deliberates and decides onpolicies ensuring safe utilization of nuclear energy. As the responsible regulatory bodies for ensuringsafety, NISA of METI, the STPB of MEXT and the PFSB and the HPB of the MHLW regulate andissue guidance on licensing process for relevant activities within their particular areas of competences.
Operators of nuclear facilities conduct their activities according to these policies and regulations
mentioned above.
Following are the national policies on spent fuel management and radioactive waste management asstated in the Program, etc., as well as the implementation plans established by the government ofJapan and the practices conducted by operators of nuclear facilities.

B. 1

Spent Fuel Management Policy

The Program states that nuclear power generation should contribute to energy supply system in Japanas an economical, stable and environmentally acceptable source of energy, and that nuclear fuel cycle
technologies have the potential to further improve these aspects, having possibilities for people toenjoy the benefits of nuclear power generation over a long period of time. Recognizing these features,and the geographical conditions and energy resources of the country, and considering the economical
conditions, Japan has made it a basic policy to reprocess spent fuel and to make effective use of therecovered uranium, plutonium and other usable elements, while ensuring safety and nuclear
non-proliferation. Also, Japan intends to reprocess all spent fuel within the country as a national policy,
ensuring self-sustainable nuclear fuel cycle. The Program also states that interim storage of spent fuelensures flexibility in the nuclear fuel cycle, allowing sufficient time before reprocessing.
There are concerns about safety and nuclear proliferation related to the use of plutonium recoveredfrom reprocessing of spent fuel. To address these concerns, Japan is making doubly sure to ensure
safety and nuclear non-proliferation, and to make policy of Japan understood in the international
community.

B. 2

Spent Fuel Management Practices

Spent fuel generated in power reactors are sent to reprocessing facilities after a period of on-site
cooling and storage. The spent fuel has been reprocessed overseas in accordance with contracts with
British and French companies, with the exception of a portion reprocessed by the Tokai Reprocessing

B-1

Plant of the JNC. In the meantime, considering national demand for reprocessing, JNFL began
constructing the Spent Fuel Reprocessing Plant in Rokkasho-mura, based on operational experience
accumulated at the Tokai Reprocessing Plant and on technologies and experience from advanced
countries. The plant was in the situation of test operation using uranium in March 2005, and will start
operation from 2007. Storage of spent fuel at storage facility in the plant started since 1999, and exportof spent fuel to foreign reprocessing plants ended in July 2001.
The Reactor Regulation Law was amended in 1999 to incorporate provisions on interim spent fuelstorage, and a company is currently preparing for commercial operation of interim fuel storage
facilities in 2010.
The spent fuel from research reactor facilities has been exported to the USA, or is to be reprocessed inJapan.

B. 3

Radioactive Waste Management Policy

The AEC, in its Program and other documents, states that the current generations, whichenjoy the benefits of nuclear energy, are obliged to make their utmost to ensure the safe
disposal of radioactive waste generated in the research, development and utilization of
nuclear energy, and should invest continued efforts in achieving this obligation. The AEC
states that the operator of the facility that produces waste has the primary responsibility forsafe processing and disposal of the waste and that the government has the responsibility fortaking necessary measures to ensure that this processing and disposal are carried out
appropriately and safely by the producers, through giving adequate guidance and setting
necessary regulations. Further, the AEC states that the government should play anappropriate role in implementing the disposal program for radioactive waste, with a view toensuring long-term safety, in addition to its activities related to promotion of research anddevelopment activities and safety regulation.

The AEC states that nuclear facilities should be decommissioned safely by the responsibility of license
holder with understanding and support of the local community, and also states that generation ofradioactive waste should be minimized. The AEC encourages research and development efforts aimed
at recycling and/or reusing waste.
METI and MEXT have established and continued to improve the legal framework consisting of theReactor Regulation Law and the Radiation Hazards Prevention Law, for safe and proper processing,storage and disposal of radioactive waste, on the bases of studies and decisions made by the AEC andthe NSC.
Among these regulations, the criteria for gaseous and liquid radioactive waste discharge have been
established in accordance with relevant international recommendations.
Solid radioactive waste is classified into two categories, namely HLW (liquid waste generated fromspent fuel reprocessing and its vitrified package) and other LLW. The LLW is sub-classified according
to origin (differing radionuclide composition) and level of radioactivity, as shown in Table B. 3-1.
The Reactor Regulation Law was amended in May 2005 to provide for clearance level and theprocedure for its monitoring for compliance, while the relevant regulations are going to be establishedin future.
The AEC makes decision on the basic policy for radioactive waste disposal. Based on the policy, theNSC decides on the basic concept for the safety regulations for land disposal (*1), upper bounds ofradioactivity concentration for disposal of radioactive materials and methods for safety assessment ofdisposal facilities. METI and MEXT establish relevant regulations. Table B. 3-2 shows the status of
regulatory activities aimed at preparing the relevant regulations for radioactive waste disposal.
A summary of the basic concepts for radioactive waste disposal shown in Table B. 3-2 is as follows.
B-2

There are two basic concepts for land disposal, i.e. “geological disposal” and “near surface andintermediate depth disposal with institutional control”. The near surface and intermediate depth
disposal consists of near surface disposal with artificial barrier (concrete vault), near surface disposal
without artificial barrier (trench) and intermediate depth disposal (disposal at a depth sufficient tosafety margin for conventional underground building). HLW is disposed of solely by geologicaldisposal, and LLW can be disposed of either by geological disposal or near surface and intermediate
depth disposal with institutional control, depending on the property of the waste. Vitrified HLW isemplaced in a stable geological formation at a depth of more than 300 meters, following 30 to 50 years
of interim storage to allow cooling. Among LLW from power reactors, relatively higher radioactive
wastes are disposed of in intermediate depth disposal facilities, relatively lower radioactive waste aredisposed of in near surface disposal facilities with artificial barriers, and very low level waste aredisposed of in near surface disposal facilities without artificial barriers. Radioactive wastes containing
transuranic nuclides from reprocessing process, uranium waste from enrichment and/or fuelmanufacturing, and radioactive waste from medical, industrial and research facilities are disposed ofeither by geological disposal or near surface and intermediate depth disposal with institutional control,
depending on types of radionuclides and levels of radioactivity. In the future, discussions will continue
on measures that can be taken to provide different disposal methods in a single disposal facility, or todispose of wastes of different origin in a single disposal facility.
Concerning the regulations for disposal of LLW from power reactors, the upper bounds ofradioactivity concentration, to be applied for license for radioactive waste disposal, have already been
established on the basis of the Reactor Regulation Law. The radioactive waste returned from overseas
reprocessing is to be disposed of together with waste from domestic reprocessing.
The Specified Radioactive Waste Final Disposal Act, enacted in the year 2000, provides for theestablishment of an implementing organization for disposal of HLW, the financial resources reserved
for disposal, and procedure for selecting a disposal site, etc. The nuclear industry established Nuclear
Waste Management Organization of Japan (NUMO), the implementing organization for HLW
disposal approved by the government on the basis of the law.
The NSC issued the “Basic Concept of Regulation on HLW disposal” in November 2000, andindicated a schedule to establish basic guidelines for safety examination before the selection of thedetailed investigation area, and other guidelines for safety examination before the start of the safety
examination of the disposal facility.
In compliance with the Convention on the Prevention of Marine Pollution by Dumping of Wastes andOther Matter (1972) and its amendment to Annex I in 1993, the AEC decided on November 2, 1993 toeliminate the option of sea dumping of radioactive waste. Based on this decision the Reactor
Regulation Law was amended in May, 2005.

Government Activities related to Radioactive Waste Management

The regulatory body establishes regulations on HLW disposal, while NUMO is responsible for
implementing HLW disposal economically and efficiently. Japan Nuclear Cycle Development
Institute and other national institutes conduct various programs to develop safety assessment
methodology, to promote fundamental research on deep geological formation, etc. and to enhancereliability of geological disposal technology.

The Nuclear Safety Committee issued a report "Environmental Requirements to be Considered at the
Selection of the Preliminary Investigation Areas for High-Level Radioactive Wastes Disposal" in
September 2002. The environmental requirements shown in the report are reflected in the report of NUMO"Considerations for Selection of the Preliminary Investigation Areas".
Furthermore, the Committee made a report "Nuclear Research Programs Important to Safety" in July 2004,
which shows the environmental requirements at the selection of the detailed investigation areas andresearch tasks necessary for study of the basic guidelines for safety examination. And also, the said
program describes research tasks for development of the basic idea for safety evaluation concerning
processing and disposal of low-level wastes of comparatively high radioactivity, TRU wastes and uranium
wastes in addition to the decommissioning technology.

The Radioactive Waste Safety Subcommittee of the Nuclear and Industrial Safety Subcommittee
issued, in July 2003, a report titled “Toward Establishing Framework of Safety Regulation of HLW”,
which shows future objects of research and discusses research support organization to the regulatory
body.
Partitioning and transmutation is a technology to separate radioactive materials with long half-lives in
HLW from the rest of the waste and convert them into short half-lives or stable materials. This
technology, even though it is still in early stage of development, should be further pursued because it
may contribute to reduction of waste processing and disposal cost and to effective use of available
resources.

B. 4. 2

Radioactive Waste Management Practices by Operators

Operators, recognizing their responsibility concerning radioactive waste management addressed in B.3,
shall manage radioactive waste generated at their facilities in compliance with the Reactor Regulation
Law, the Radiation Hazards Prevention Law and relevant regulations.
(1)

High-Level Radioactive Waste Management Practices
In Japan, spent fuel has been reprocessed by the Tokai Reprocessing Plant of the JNC and by
reprocessing plants in France and the United Kingdom. JNFL is constructing a vitrification facilityof HLW, attached to its reprocessing plant, at Rokkasho-mura in Aomori prefecture. This facility
is to be completed by 2007. High-level liquid waste generated at the Tokai Reprocessing Plant of
the JNC is stored in storage tanks within the facility. The vitrification facility started operation in
January 1995. As of March 2005, about 400 cubic meters of liquid waste and 169 vitrified waste
canisters are in storage. Utilities in Japan have concluded reprocessing contracts with British andFrench companies for a total of 5,600 t U of spent fuel from light water reactors and 1,500 t U ofspent fuel from a gas cooled reactor. In accordance with these contracts, vitrified waste canisters
are returned to the utilities and are stored by JNFL. By March 2005, 892 vitrified canisters had
been returned, and a total of 2,200 canisters will have been returned, with remaining packages
being returned in the next ten-odd years.
Vitrified HLW will be disposed of by geological disposal. Based on the Specified Radioactive
Waste Final Disposal Act, the Nuclear Waste Management Organization of Japan (NUMO), theresponsible implementing organization, will start disposal in late 2030s after three steps procedureof site selection, that is, selection of the preliminary investigation areas, detailed investigation
areas and final disposal facility. NUMO, in 2002, started the first step by open solicitation ofcandidate of sites for the preliminary investigation areas, and published the “application format”,“outline of the disposal facility”, “investigation items” and “coexistence of disposal facility andlocal community”. In case of receiving proposal of candidate areas, NUMO will assess validity of
the candidates by conducting survey of the site with existing literature on volcanic activities,
active faults and other geological conditions, and will decide the preliminary investigation areas

by 2010.
Low-Level Radioactive Waste Management Practices
As shown in B. 3. 1, LLW is classified into waste from power reactors, waste containing
transuranic nuclides, uranium waste and radioactive waste from medical, industrial and researchfacilities. The waste management strategy for each of these categories is as follows, while gaseousand liquid radioactive wastes are discharged under monitoring, after attenuation of radioactivity,
filtering, adsorption and/or distillation. (see H.6.5)
1)

Waste from Power Reactors
As of March 2005, fifty-six nuclear power reactors were in operation. Liquid waste
concentrate is solidified with cement in drums after evaporation. Paper, clothing and othercombustibles are placed in drums after incineration. Plastics, metals and othernon-combustibles are placed in drums after compaction. Replaced steam generators and otherlarge-volume solid wastes are placed in storage facilities. Replaced control rods and channel
boxes, etc. are stored in spent fuel pools and spent ion exchange resins are stored in tanks.
Near-surface disposal of solidified liquid waste and compacted and solidified non-combustible
wastes started in 1992 at the disposal facility of JNFL at Rokkasho Village in Aomori
Prefecture.
Concerning decommissioning activity in Japan, dismantling of the Japan Power
Demonstration Reactor (JPDR) completed in May 1996. The very low-level concrete waste
generated by dismantling was disposed of at a disposal facility, which was closed in 1997. A
reactor at the Tokai Power Station of the Japan Atomic Power Co. ceased operation in 1998
and has been in decommissioning stage since December 2001. The advanced thermal reactor“Fugen” of JNC ceased operation in March 2003. Spent fuel is being transferred to Tokai
Facility of JNC, and decommissioning is being planned.
For non-radioactive waste generated in non-nuclear facilities, the waste generators arerequested to minimize the generation, to reuse, to reprocess / reuse and to dispose
appropriately of waste.
As shown in B.3, The Reactor Regulation Law was amended in May 2005 to provide forclearance level and the procedure for its monitoring for compliance. For those waste generated
in nuclear facilities and monitored for compliance as non-radioactive waste, it is necessary to
reprocess / reuse and to minimize the volume of waste to be finally disposed of, with theunderstanding and cooperation of the people and community.
Before the clearance level system is generally accepted in the society, electric utilities are
considering that the non-radioactive waste generated from the dismantling of nuclear power
plants are to be treated by those waste processors conscious of clearance level system, and tobe shipped to the specified disposal facilities and that electric utilities are to reprocess / reuse
non-radioactive waste within their nuclear power plant sites.

2)

Waste Containing Transuranic Nuclides
Liquid transuranic waste generated at the Tokai Reprocessing Plant of JNC is stored in tanks
and concentrated by evaporation, and a portion of it is solidified in drums. Segmented fuelcladding, used filters and sampling bottles are put in containers and other solid waste is put indrums. These drums and the containers are being held in storage at on-site storage facilities.
Transuranic waste generated at spent fuel reprocessing plant in France and UK will be
returned to Japan after 2013. Utilities are planning to construct a storage facility for it.
Research and development programs on transuranic waste disposal have been promoted by
JNC and utilities. They published a report in June 2005 titled “Technological Report on TRU
Waste Disposal, 2nd report”.

B-5

3)

Uranium Waste
Liquid waste containing uranium generated from enrichment and/or fuel manufacturing
facilities of JNC and/or other private facilities are stored in tanks. Solid uranium waste and ash
resulting from incineration are put in drums. They are held in storage at on-site storage
facilities.

4)

B. 5

Radioactive Waste from Medical, Industrial and Research Facilities
Radioactive waste generated from medical, industrial and research facilities are collected by
the license holders of radioactive waste management facility, who store it at their own storage
facilities after compaction or incineration.
Radioactive waste generated in facilities of research reactor and fuel material use of the Japan
Atomic Energy Research Institute (JAERI), the JNC and universities are stored in drums attheir own storage facilities after compaction or incineration.
Criteria for Definition and Classification of Radioactive Waste

As shown in B. 3, radioactive waste is classified into two categories, namely HLW and LLW. Depending on
its origin, the LLW is sub-classified into waste from power reactors, radioactive waste containing
transuranic nuclides (reprocessing facility, MOX fuel manufacturing facility), uranium waste (uranium fuelmanufacturing facility, uranium enrichment facility) and radioactive waste from medical, industrial andresearch facilities.
For three subcategories of wastes from power reactors as shown in the Table B.3-1, the NSC has calculated
the concentrations of the radionuclides that correspond to the reference dose values, using consistent safetyassessment concept, models and parameters which are conformable to the international standards.
The NSC then, in consideration of the concentration distribution of the radioactive waste to be disposed of,has obtained the upper bound of the concentrations of radionuclides for radioactive waste to be disposed of(*2). Based on the value obtained as mentioned above, the upper bound of radionuclides concentrations forlicense application of waste repository has been provided in the Reactor Regulation Law. (∗3)
Moreover, the clearance system has also provided. The Atomic Energy Commission (hereinafter called
AEC) issued the report "Policy on Processing and Disposal of Radioactive Wastes" in August 1984 about
the concept of the clearance level that divides wastes into the radioactive waste and the "materials not
requiring treatment as radioactive wastes". In response to the above policy, the NSC presented a basic
concept of "materials not requiring consideration of particularities as radioactive wastes" in 1985.
Afterwards, the concept, derivation methods, etc. of the "clearance level" were provided in IAEA-TECDOC-855, in January 1996 (*4).
In such a situation, the NSC has obtained the clearance level (radionuclides concentrations) using the
calculation method accordant with that described in IAEA-TECDOC-855, and referring to the dose values
due to cleared materials shown in the recommendation by the International Commission on RadiologicalProtection (ICRP) (Pub. 46, 1985), report of the Radiation Council (1987), report of the NSC (1988),
IAEA-TECDOC-855, and other IAEA reports. The results are reported as "Clearance Level for Major
Nuclear Facilities” (March, 1999), "Clearance Level for Heavy Water Reactors, Fast Neutron Reactors,etc." (July, 2001), and "Clearance Level for Nuclear Fuel Use Facilities (Facilities dealing with irradiatedfuels and materials” (April, 2003).
Under the circumstances that the dismantling program of gas cooled reactor in the Tokai Power Station ofJapan Atomic Power Company has become active, and IAEA issued the Safety Guide “Application of theConcepts of Exclusion, Exemption and Clearance”, Safety Standards Series No. RS-G-1.7 (2004), the NSC
has made a re-evaluation of the above mentioned three reports on the clearance level taking the latest
findings etc. about application concepts of exemption level and evaluation methods shown in RS-G-1.7 into
account. The results were issued as a report "Radionuclides Concentrations for Materials not Requiring

B-6

Treatment as Radioactive Wastes, Generated from Dismantling etc. of Reactor Facilities and Nuclear Fuel
Use Facilities" in December, 2004. The NSC concluded that though the former values are comparable to
the re-evaluated values, it is necessary to use the latter values since new findings are incorporated. In
addition, it was concluded that though the re-evaluated values and the values of exemption level provided
in the IAEA safety guide are comparable, it is suitable to use the latter values to keep the international
consistency. The Radioactive Wastes Safety Subcommittee of the Nuclear and Industrial Safety
Subcommittee also studied this matter and concluded that it is essentially suitable to use the values of the
IAEA safety guide ("Establishment of the Clearance System for Nuclear Facilities (December, 2004)).
Moreover, the Radioactive Waste Safety Subcommittee led conclusions about the validation of clearance
level in the report that the party who generated the waste should judge that their waste concerned is below
the clearance level, and then, the government should be appropriately involved in the confirmation. The
involvement by the government should be composed of two steps, i.e., the first step includes authorizationof "methods of measurement for concerned materials and clearance judgment based on the measurement
values" prepared by the operator, and the second step includes confirmation that the actual measurements
and judgment are properly done by the authorized methods by checking records and by samplingmeasurement as required.
As the results of these studies, the Reactor Regulation Law was amended as mentioned above and theclearance system will be started its application.
Besides, the NSC showed the basic concept to distinguish “solid wastes that are not radioactive wastes”
from radioactive wastes in the report " Reference Radionuclides Concentration Values for Low-level
Radioactive Solid Waste to be Land Disposed (interim report)” (December, 1986). The solid wastes which
are not radioactive wastes are materials which have totally no potential contamination with radioactive
materials or materials of which radioactive level is not admitted to be significantly different from thenatural levels.

Disposed (interim report)”, NSC, December, 1986, " Reference Radionuclides Concentration Values for
Low-level Radioactive Solid Waste to be Land Disposed (the 2nd interim report)”, NSC, June, 1992, and "Reference Radionuclides Concentration Values for Low-level Radioactive Solid Waste to be Land Disposed(the 3rd interim report)”, NSC, September, 2000
*3: The upper bounds of radionuclides concentration provided in Paragraph 2 of Article 13-9 of theOrdinance for the Enforcement of the Reactor Regulation Law. But at the review of a license application ofwaste disposal, in addition to the radionuclides concentration, the safety of each waste disposal facility has
to be examined for license issuance.

Legislative and Regulatory Framework (Article 19)

Each Contracting Party shall establish and maintain a legislative and regulatory framework
to govern the safety of spent fuel and radioactive waste management.
This legislative and regulatory framework shall provide for:(i)the establishment of applicable national safety requirements and regulations forradiation safety;(ii) a system of licensing for spent fuel and radioactive waste management activities;(iii) a system of prohibition for the operation of a spent fuel or radioactive waste
management facility without a license;(iv) a system of appropriate institutional control, regulatory inspection anddocumentation and reporting;(v)

the enforcement of applicable regulations and of the terms of the licenses;(vi) a clear allocation of responsibilities of the bodies involved in the different stepsof spent fuel and radioactive waste management.
When considering whether to regulate radioactive materials as radioactive waste,
Contracting Parties shall take due account of the objectives of this Convention.
E.2.1

Basic Legislation Regulating the Utilization of Nuclear Energy

The basic law on the utilization of nuclear energy in Japan is the Atomic Energy Basic Law that wasestablished in 1955. The objectives of the law are quoted as “to secure future energy resources, achieve
progress in science and technology, and promote industry, by encouraging research, development, andutilization of nuclear energy, and thereby contribute to the improvement of the welfare of human society
and the national living standard.” The basic policy here is prescribed as follows: “The research,development and utilization of nuclear energy shall be limited to peaceful purposes, on a basis of
ensuring priority to safety, and performed on a self-disciplined basis under democratic administration,and the results thereof shall be made public and actively contribute to international cooperation.”
In order to attain these objectives and achieve the basic policy, the law prescribes the following:- Establishment of the AEC and the NSC, and their duties, organization, administration, andauthorities- Regulations on the nuclear fuel materials- Regulations on the construction, etc. of reactor facility.
- Prevention of radiation hazards
The law also prescribes the assignment of these matters to the respective laws.
E.2.2

Legislative and Regulatory Framework on the Safety of Nuclear Utilization

Major laws established for the purpose of providing safety regulations on the utilization of nuclear
energy and related laws include “the Law for the Regulation of Nuclear Source Material, Nuclear Fuel
Material and Reactors (the Reactor Regulation Law)”, “the Electricity Utilities Industry Law,” “the Law
Concerning Prevention from Radiation Hazards due to Radioisotopes, etc. (the Radiation Hazards
Prevention Law)” and “Medical Care Law, etc.” Also included are “the Basic Law for General
Emergency Preparedness,” “the Special Law of Nuclear Emergency Preparedness (the Special Law for
Nuclear Emergency),” “the Law for Technical Standards of Radiation Hazards Prevention” and “theSpecified Radioactive Waste Final Disposal Act,” etc. Overviews of these laws are provided in thefollowing paragraphs.
E-2

Besides the laws mentioned above, “the Law for Establishment of the AEC and the NSC,” “the Ministryof Economy, Trade and Industry (METI) Establishment Law,” “the Ministry of Education, Culture,
Sports, Science and Technology (MEXT) Establishment Law,” “the Ministry of Health, Labour andWelfare (MHLW) Establishment Law,” “the Japan Nuclear Energy Safety Organization Establishment
Law,” etc. establish the administrative organizations responsible for the safety regulation of nuclear
facilities.
The major laws related to the safety regulation of nuclear facilities are shown in Tables E.2-1 (a) and (b).
(1)

The Law for the Regulation of Nuclear Source Material, Nuclear Fuel Material and Reactors(the Reactor Regulation Law) and the Electricity Utilities Industry Law

In accordance with the objectives of “the Atomic Energy Basic Law”, the Reactor Regulation Law, toensure that the uses of nuclear source material, nuclear fuel material, and reactors are limited topeaceful purposes, and carried out in a planned manner, and to ensure public safety by preventing
hazards and providing physical protection of nuclear fuel material. The Reactor Regulation Law
provides on the safety requirement for the following facilities and activities:- Nuclear fuel fabrication- Establishment and operation of reactor facilities- Spent fuel storage- Spent fuel reprocessing- Radioactive waste disposal- Use of nuclear fuel material, etc., and- Radioactive waste management outside of the licensed site.
The safety of the management of spent fuel generated in a reactor facility and stored on site, spent fuelstored off site or spent fuel brought into and stored in a reprocessing facility, is regulated by theprovisions on the establishment and operation of reactor facilities, by the provisions on the spent fuelstorage or by the provisions on the spent fuel reprocessing, respectively.
As radioactive wastes generated at enrichment and/or fuel manufacturing facilities, reactor facilities,
spent fuel storage facilities, reprocessing facilities, fuel material use facilities, etc. are stored orprocessed in associated facilities of the respective facility, the safety of their management is regulatedby the provisions on respective activities. Meanwhile, the provisions on radioactive waste disposal
regulate the safety of waste disposal and related waste management.
The Reactor Regulation Law stipulates following provisions on various nuclear facilities, taking
account of characteristics of each facility.
- Regulations on basic design or design policy at the time of facility establishment(Licensing)- Regulations on detailed design at the time of facility construction (Approval of Design
and Construction Methods)- Inspections at the time of facility construction (Welding Inspection, Pre-Service
Inspection)- Regulations for safe maintenance and operation (Approval of the Operational Safety
Program, and the Nuclear Safety Inspection)- Inspections of facility during operation (Periodical Inspection of Facility)

E-3

- Measures taken for securing safety of facility- Record management- Report collection- Regulations on facility transfer, and succession or merger of operator- Decommissioning- Safety verification on radioactive waste package for disposal (Waste Disposal).
- Monitoring for compliance with clearance revel
The content of major regulations is as follows:
At the stage of issuing the License for Establishment of a nuclear facility, the regulatory body
conducts an examination to determine adequacy of the site and adequacy of the basic design ofstructure and equipment from the point of prevention of radiological hazards. In addition, theregulatory body confirms that the nuclear facility will not be used for non-peaceful purposes, thelicense accommodates to planned development and utilization of atomic energy, and the applicant
planning to establish the nuclear facility has sufficient technical capability to ensure safety andsufficient financial resources to execute the plan.
At the stage of Approval of the Design and Construction Methods of nuclear facilities, the regulatory
body evaluates detailed design to determine whether the structures, system and components to beconstructed are in accordance with the above basic design, as well as in compliance with national
technical standards.
At the stage of construction, the regulatory body conducts the Pre-Service Inspection and the Welding
Inspection of pipes, components, etc. to confirm whether the construction of facilities and the
manufacturing of the components are in accordance with the detailed design mentioned above.
During operation, the regulatory body also conducts the Periodical Inspection of Facilities tocontinually confirm the integrity of the facilities and equipment. The operators are required to reportand keep operation records.
In the radioactive waste disposal, the regulatory body confirms whether the radioactive waste
disposal facility, the waste packages and the safety measures are in accordance with the technicalstandards.
At the operation of a nuclear facility, in addition to regulations focusing on the integrity of structural
aspects described above, an assessment is also conducted concerning managerial aspects of theoperator such as the organization, reporting system, operating procedure, equipment maintenance,
surveillance, radiation control for personnel, radioactive waste management, radioactive gaseous andliquid waste discharge, radiation monitoring and safety education for personnel, quality assurance, etc.
These aspects are comprehensively documented in the Operational Safety Program, which should beapproved by the regulatory body. By the amendment of the Reactor Regulation Law in October 2003,
operator’s quality assurance program is included in the Operational Safety Program, the Nuclear
Safety Inspection system is established, and the Nuclear Safety Inspectors who confirms compliancewith the Operational Safety Program are stationed at each nuclear facility. The allegation system,
established by the Reactor Regulation Law, was revised so that personnel can allege violation ofsafety regulation to the NSC as well as to NISA without any unfavorable treatment. The rules under
the law provides that the personal data of alleger be protected. The rule also provides for adequate
procedures for investigation and disclosure of alleged case.
By the amendment of the Reactor Regulation Law in May 2005, regulatory procedure ofdecommissioning was defined and clearance system was newly introduced.
Concerning the decommissioning of the nuclear facilities, the operator submit to NISA
decommissioning plan describing decommissioning process and method, and starts decommissioning
process after obtaining approval . NISA confirms the decommissioned site after completion ofE-4decommissioning. Graded safety regulation is applied, as the decommissioning process proceeds.
Details are shown in Section F. 6.
Concerning the clearance system, clearance level is defined as “radioactivity concentration level ofthe materials, on which no measures are required to prevent hazard due to the radiation”. The operator
carry out measurement and estimate radiation concentration level by the method approved by NISA.
NISA confirms the results. Then, the substance can be treated as unpolluted substance. Detailed
regulations both on decommissioning and clearance level will be established in future.
Provisions on the Construction Plan, the Pre-Service Inspection and the Periodic Inspection of theElectricity Utilities Industry Law apply to a commercial power reactor facility, as it is also an electricfacility, and the corresponding provisions of the Reactor Regulation Law are exempted fromapplication in order to avoid duplication of regulation. As the relevant provisions of these two laws
are similar each other, these two laws are referred to as the “Reactor Regulation Law etc.” hereinafter.
Some of these provisions of the Electricity Utilities Industry Law were amended in October 2003.
Details of the amendment should be referred to the “National Report of Japan for the Third Review
Meeting of the Convention on the Nuclear Safety”.
As shown in Figures E.2-1 (a) and (b), rules and standards are established for each nuclear facilities
under the Reactor Regulation Law. When conducting safety examination of a nuclear facility, safety
regulatory guides. (Table E.2-1) established by the NSC are used. In addition, appropriate academic
society and association Standards. (Table E 2-2) are used as necessary.

The Law Concerning Prevention from Radiation Hazards due to Radioisotopes, etc. (TheRadiation Hazards Prevention Law)

The objectives of the Radiation Hazards Prevention Law are to prevent radiation hazards of theworkers and public on the use of radioisotopes, radiation generating devices, and material
contaminated with radioisotopes, etc.
As shown in Figure E.2-1 (a), the Ordinance and Rules for the Enforcement of the Radiation Hazards
Prevention Law are established.
A license holder for radioisotope distribution, lease of the radiation equipment and waste
management and use a radiation generating device under the Radiation Hazards Prevention Law is
obligated the Pre-Service Inspection and the Periodic Inspection to confirm if they have sufficient
capacity of the storage facility.
Those who use the facility licensed under the Radiation Hazard Prevention law must compile a set of
the Internal Rules for Prevention of Radiation Hazards, designate the Qualified Staff of Radiation
Protection, and notify these results to the regulatory body before use of facility. Furthermore, those
who use the facility have an obligation to conform to the criteria for facilities to be used, which havebeen established by legislation. Other obligations include: measuring the radiation doses within thepremises or on the boundary of the establishment; measuring the exposure doses of the occupational
personnel; providing education and training; and conducting health examinations, etc (some ofoperators are excluded).
Regarding management of radioisotopes or materials contaminated with such radioisotopes generated
from radioisotopes using facility must be carried out in conformity with the criteria established bylaws and regulations within the premises of licensed facility or the premises of the licensed facility ofradioisotope waste management.
Legislation on disposal of radioisotope wastes mentioned above is in preparation.
When the use of radioisotopes or radiation generating devices is to be discontinued, a notify
describing the measures adopted as part of the discontinuation (abolishing) procedures must be
E-5submitted to the Minister of MEXT, along with a notice of such discontinuation (abolition)
If necessary, MEXT gives instruction for the Radiation Inspectors to conduct an on site inspection inorder to ascertain the state of compliance with the standards established by laws and regulations.

Medical Care Law, etc.

(Waste management facility operators designated by the Minister of MHLW) conduct) Radioisotope(radioisotope) waste management for medical use, on the basis of the Medical Care Law etc. (theMedical Care Law, the Clinical Laboratory Technicians and Health Laboratory Technicians Law, and
the Pharmaceutical Affairs Law) is conducted by the designated operators.
Site, structure, and equipment of the waste management facility have to comply with related technicalcriteria (standards) in order to be designated by the Minister of MHLW and Welfare.
Furthermore, Periodical Inspection, Radiation Hazard Prevention Rules, conformance order to thestandards of waste management facilities, education and training, notification of closure of waste
management facility, etc, are provided by these laws equivalent to (the same as by) the Radiation
Hazards Prevention Law.
(4)

The Basic Law for General Emergency Preparedness and the Specific Law for Nuclear
Emergency Preparedness

The measures to be taken at a nuclear emergency are addressed by the Basic law for General
Emergency Preparedness and the Specific Law for Nuclear Emergency Preparedness. The Specific
Law stipulates specific measures for nuclear emergency, including obligation of operators to prevent
occurrence of nuclear emergency, the Declaration of Nuclear Emergency and establishment of
headquarters for the nuclear emergency (Response Headquarters), and enforcement of emergency
measures. The Senior Officer for Nuclear Emergency is stationed in the vicinity of each nuclear
facility, to direct and advise the operator in preparing its Plan for Nuclear Emergency Preparedness,
as well as to conduct its duty to prevent occurrence of nuclear emergency and mitigate consequences
should it occur.
Moreover, In the part of the nuclear emergency measures of the Basic Plan for Emergency
Preparedness on the basis of the Basic Law for General Emergency Preparedness, measures necessary
to prevent occurrence and progression of nuclear emergency, where an abnormal level ofradioactivity is released outside the nuclear facility, and to recover from the emergency is described.
(5)

The Law for Technical Standards of Radiation Hazards Prevention

The objectives of the Law for Technical Standards of Radiation Hazards Prevention are to clarify thebasic policy for defining technical standards for radiation hazards prevention and to establish theRadiation Review Council of MEXT, so that consistency of technical standards for radiation hazards
prevention can be realized. "The Radiation Review Council Orders" are stipulated under the Law forTechnical Standards of Radiation Hazards Prevention.
(6)

The Specified Radioactive Waste Final Disposal Act“The Specified Radioactive Waste Final Disposal Act”, established in May, 2000 provided theframework for the planned and steady final disposal of “Specified Radioactive Waste” which is highlevel radioactive waste (HLW) resulted from reprocessing of spent nuclear fuel. The major points of
the law are, (1) the government establishes basic policy and plan on final disposal of specific wastes(Final Disposal Plan), (2) establishment of an implementing organization, (3) measures to secure
financial resources for disposal, and (4) site selection procedure. Figure E.2-2 shows the basic schemeE-6

of the procedures. The Minister of METI establishes basic policy and based on this, provides Final
Disposal Plan. Nuclear Waste Management Organization of Japan (NUMO), which was established
as an implementing organization based on the Final Disposal Plan, carries out the activities of final
disposal. Utilities shall contribute financial resources to the fund reserved for disposal, which ismanaged by an organization designated by the Minister of METI (RWMC). NUMO promotes site
selection by a three step procedure, that is, selection of the preliminary investigation area, detailed
investigation area and site for disposal facility, and obtain approval of the Minister of METI at eachstep of procedure.
The three step procedure for site selection is as follows, and items for investigation and evaluation are
clearly defined.
•

Preliminary investigation area
Definition: The area to investigate by boring etc. whether the geological formation concerned isstable for long term .
Requirements for selection: There shall be no record of remarkable variation of the geologicalformations by natural phenomena, such as earthquakes.

•

Detailed investigation area
Definition: The area to investigate, by constructing underground facility with testing andmeasuring equipment, whether the property of the geological formation concerned is suitablefor construction of disposal facility.
Requirements for selection: Remarkable variation of the geological formations by natural
phenomena, such as earthquakes, has not occurred for long term.

•

Selection of Final disposal facility construction site
Definition: The site where the final disposal facility is to be built.
Requirements for selection: It is expected that underground facility to be built within thegeological formation will not be attacked by an extraordinary pressure, and that physicalproperty of the geological formation is suitable for the final disposal facility.

When a site is selected as the final disposal facility, The Minister of METI have to consult withgovernors and local governments, and revise and finalize the Final Disposal Plan as appropriate
considering the opinions.
The safety regulations for the disposal of specified radioactive wastes are to be establishedseparately.
(7)

The Law for Deposit and Management of the Fund Reserved for Spent Fuel Reprocessing etc.
in the Nuclear Power Generation.

This law, established in May 2005, provides the frame work for deposit and management of the fundreserved for spent fuel reprocessing. The fund is managed by an organization designated by the Ministerof METI (Fund Management Organization). The Minister of METI, every fiscal year, notifies utilitiesof the amount of deposit based on the amount of electricity generated by the nuclear fuel, and utilities
deposit the amount in the Fund Management Organization.
Related regulations are being prepared.
E.2.3

Regulatory Framework for the Safety of Spent Fuel Management

As described in Section E.2.2 (1), the safety of management of spent fuel on a reactor facility or a
reprocessing facility is regulated by the provisions of the Reactor Regulation Law concerning theestablishment and operation of reactor facility or a operation of reprocessing plant, respectively. Morespecifically, spent fuel management facilities are regulated as facilities in affiliation with main facilities.
Details of the safety regulations for spent fuel management are described in Section G.

E-7

On the other hand, the safety of management of spent fuel stored outside of a reactor site or a
reprocessing plant site is regulated in accordance with the provisions of the Reactor Regulation Law
concerning spent fuel storage, and provisions on licensing, permission, approval and inspections of aspent fuel storage facility are regulated as an independent facility. At present, there is no independent
storage facility in operation, under construction or in the process of license application in Japan.
E.2.4

Regulatory Framework for the Safety of Radioactive Waste Management

As described in Section E.2.2 (1), radioactive wastes generated at enrichment and/or fuel manufacturing
facilities, reactor facilities, spent fuel storage facilities, reprocessing facilities, fuel material use facilities,
etc. are stored or processed in associated facilities to the respective facility, and the safety of their
management is regulated by the provisions on respective facility and activities.
The provisions on radioactive waste disposal facility and activities regulate the safety of waste disposal
and related waste management. The “Specified Radioactive Waste Final Disposal Act”, mentioned E2.2(7), provides for the funds reserved for HLW final disposal, the procedure for selecting disposal site, etc.,
other safety regulations for HLW final disposal to be established separately from the Act.
Details of the safety regulations for the radioactive waste management of the radioactive waste disposal
facility and activities are described in Section H.
The safety of the radioisotope waste management at facilities licensed under the Radiation Hazards
Prevention Law is regulated as described in Section E.2.2 (2).
The safety of the radioactive waste management at facilities licensed under the Medical Care Law, etc. isregulated as described in Section E.2.2 (3), and relevant provisions are similar to those in the Radiation
Hazards Prevention Law. Therefore, description of the safety of waste management under the Medical
Care Law is omitted in Sections F and thereafter.
E.2.5

The Enforcement of Applicable Regulations and the Terms of the Licenses

The Reactor Regulation Law and the Radiation Hazards Prevention Law prescribes imprisonment
and/or fines under circumstances such as establishing a nuclear facility without a license, violating a
Shut-Down Order, or failing to take relevant emergency measures. The competent minister, on the basisof the Reactor Regulation Law, the Radiation Hazards Prevention Law or the Medical Care Law, etc.,
may revoke the license or impose other administrative measures under circumstances such as starting
operation of a nuclear facility or use of fuel materials without a license, violating an order legally issued
by the regulatory body, failing to implement measures necessary for operational safety prescribed by theregulatory body, operating nuclear facility without the Operational Safety Program or the Internal Rules
for Prevention of Radiation Hazards (the Operational safety program, etc.) approved by the regulatory
body, or failing to comply with the Operational Safety Program, etc.
The regulatory body may order changes in the Operational safety program, etc., whenever it is deemednecessary for preventing accident. License holders failing to abide by such orders could be punishedwith a fine.

E-8

E.2.6

Clear Allocation of Responsibilities in the Different Steps

An operator of nuclear facilities shall have an approved license for each of the steps in a series ofprocesses including generation, storage and reprocessing of spent fuels. The allocation of
responsibilities within the regulatory body that issues license for each of these steps is clearly defined as
illustrated in the report of Article 20 (Section E.3.3, Table E.3-1).
The responsibilities of operators of facilities those produce waste and the operators of radioactive waste
disposal facilities have been allocated in accordance with the fundamental concept shown by the AEC
in the report, "Policy on Radioactive Waste Processing and Disposal" (October 8, 1985, the Special
Committee on Radioactive Wastes). The report says that while the waste generators should bear overall
responsibility for management of the wastes, it is more appropriate the operator of consolidated low
level radioactive waste disposal facility take the legal responsibility for the safe operation in order to
execute efficient activities with clear responsibility for ensuring safety. And it also says that the waste
generator should make every support for the operator of the consolidated disposal facility to ensure thedisposal operation of the waste smoothly.
As shown in E.2.2, the activities for radioactive waste management stream, from the generation ofradioactive wastes, processing and storage, shipment, to disposal are regulated by the Reactor
Regulation Law without any discontinuity. The regulation for disposal of radioactive wastes (Table
B.3-2) is under preparation keeping consistency among divisions of radioactive wastes (Table B.3-1).

assigned responsibilities.
Each Contracting Party, in accordance with its legislative and regulatory framework, shalltake the appropriate steps to ensure the effective independence of the regulatory functions
from other functions where organizations are involved in both spent fuel or radioactive waste
management and in their regulation.
E.3.1

Mandate of the Regulatory Bodies

The mandate of the regulatory bodies is to ensure public safety through securing safety of nuclear
facilities, and their obligations are to implement the legislative and regulatory framework described in
the report of Article 19. The regulatory bodies are responsible for conducting regulatory activitiesprescribed in the Reactor Regulation Law, the Radiation Hazards Prevention Law, etc. on the basis of theAtomic Energy Basic Law. Their organizations and assigned obligations are clearly defined in theirrespective establishment laws, and their financial resources are covered by the national budget.
The Minister of METI serves as the competent minister for safety regulation on activities concerning
utilization of nuclear energy, and NISA administers the regulatory activities as a special organization for
METI. The Minister of MEXT serves as the competent minister for the safety regulation over the
nuclear utilization associated with science and technology and the utilization of radioisotopes (except

and audits activities of these regulatory bodies (Regulatory Review), and establishes the basic policy forsafety regulations therefore the consistency among the regulations is maintained. The consistency of thetechnical standards for prevention of radiation hazard is discussed at the Radiation Review Council.

E-17

E.3.2The Structure of the Regulatory Body and Supporting Organizations(1)

Nuclear and Industrial Safety Agency (NISA)The Minister of METI, as the competent minister stipulated in the Reactor Regulation Law and theElectric Utilities Industry Law, enforce the safety regulation over all activities on the utilization of
nuclear energy including nuclear power generation, and NISA was established as a specialorganization of METI to administer the safety regulation, independently from the Agency of Natural
Resources and Energy that promotes nuclear energy utilization.
The Minister of METI, as the competent minister, provided by the Reactor Regulation Law and theElectric Utilities Industry Law has the authority for examine the nuclear facilities when operators
construct them whether its siting, structure and equipment are conform for the requirement ofprevention of radiation hazards and if in the case of the licensee violate the laws, the minister has theauthority to revoke the license.
Within NISA, there are eleven divisions that administer safety regulations for nuclear facility
associated with utilization of nuclear energy. The assigned duties of each of these divisions areillustrated in Table E.3-1. The Nuclear Safety Inspectors are assigned to resident position at eachnuclear facility, with duties to conduct the Nuclear Safety Inspection four times a year to confirm
compliance with the Operational Safety Program by the operator, and to correspond to abnormal
events when they occur. The locations of offices of the Nuclear Safety Inspectors are illustrated in
Figure E.3-1.
The number of staff engaged in regulatory activities for nuclear safety including administration of
NISA is about 300, which includes about 100 persons of Nuclear Safety Inspectors and Senior
Officers for Nuclear Emergency who are resident at nuclear facilities.
Staff members who are in charge of nuclear safety regulation are required to have expertise in nuclear
technology. Knowledgeable and experienced persons are constantly recruited from outside, andspecialized and advanced education and training programs are implemented. Staff members areprovided with opportunities to attend international meetings or take long-term assignments ofworking in international organizations, etc.
Moreover, NISA maintains and develops its ability, as well as contributes to improve international
nuclear safety regulation, through exchange of technical experts and information on safety regulationand safety technology, under bilateral cooperation arrangements with foreign regulatory bodies and in
the framework of multilateral cooperation (IAEA and OECD/NEA).
On the basis of METI Establishment Law, the Advisory Committee for Natural Resources and Energy
is established, a subcommittee of which is the Nuclear and Industrial Safety Subcommittee that
consults on policies on nuclear safety and safety of electric power as the terms of reference. The
organization of the Subcommittee is illustrated in Table E.3-2. The experts in the Subcommittee areassigned based on their knowledge and experience in specialized fields including nuclear andthermal-hydraulic design, system design, seismic design, radiation control, radioactive waste disposal,
etc., and when necessary, NISA consults experts on securing of safety.
The Public Information Law, enacted in April 2001, provides for disclosure of regulatory information
on request, promoting transparency of activities on safety regulation. NISA, at the website, discloses
information on licensing of nuclear facilities, accidents and failures, radiation control and activities ofnuclear energy related councils. In April 2004, NISA established the Nuclear Safety Public Relations
and Training Division, and stationed the Regional Public Relations Officers for Nuclear Safety in theareas where major nuclear facilities are located, to further strengthen its public relation activities
including holding public meetings in local communities, distributing periodicals on activities of
NISA, etc.

E-18

In October 2003, JNES was established as a supporting organization for NISA in ensuring safety inutilization of nuclear energy, and has 420 officers and staffs. The mission of JNES is- to implement their duties effectively and rationally- to contribute to the enhancement of nuclear safety regulation,- to deliver safety information to the public by utilizing its expertise and- to foster public confidence in the safety of nuclear energy.
JNES implements the following activities to accomplish the above mission:・ Inspection of nuclear facilities and reactor facilities, and other same kind of services;・ Safety analysis and evaluation of designs of nuclear facilities and reactor facilities;
・ Activities to prevent occurrence of nuclear emergencies, to prevent progression of a nuclear
emergency, and to recover from the nuclear disaster;・ Investigation, testing, research, and training concerning ensuring safety in utilization of nuclear
power as energy.; and・ Collection, analysis and transmission of information relating to ensure nuclear safety.
The framework for JNES to implement activities and the relation of JNES with NISA are as shown in
the followings:
・ NISA develops a plan on each activity based on the regulatory needs, and defines themedium-term objective in accordance with the Law of the General Rules for Incorporated
Administrative Agency, and the Minister of METI assign it to JNES.
・ JNES prepares a medium-term program to accomplish the medium-term objective, apply the
program to the Minister of METI, and obtain the approval, then JNES prepares annual plan(fiscal year) in accordance with the medium-term program, notify the plan to the minister of
METI and implement it.
The budget for JNES is consists of government budget, incomes from commission of inspections.

The safety regulation concerning the activities around the nuclear utilization from a scientific andtechnological aspect and the utilization of radioisotopes (excluding medicines, etc.) is regulated by
the Minister of MEXT as the competent minister, and is administered by the Science and Technology
Policy Bureau (STPB).
With regard to the licensing of establishment of test and research reactor facilities and use of nuclear
fuel materials under the Reactor Regulation Law and the radioisotope waste management which
carried out as business under the Radiation Hazards Prevention Law, the Minister of MEXT has theauthority to issue the respective licenses, after conducting an examination of the site, structure andequipment from the standpoint of nuclear disaster prevention. The Minister also has the authority to
revoke the licenses under certain circumstances, such as the violation of applicable laws andregulations by the license holder.
STPB contains the Nuclear Safety Division, which has a further three offices. The assigned role ofthe divisions and offices are listed in Table E.3-1. Moreover, an inspector for the safety managementof nuclear facility is assigned to resident position at each research reactor facilities and major fuelmaterial use facilities, whose missions are to conduct examinations and inspections stipulated in theReactor Regulation Law four times a year to confirm compliance with the Operational safety programand surveillance of reactor operation management, and to respond to an emergency situation. The
locations of offices of Nuclear Safety Inspectors are illustrated in Figure E.3-1.

Nuclear Safety Commission (NSC)

The NSC, which was established within the Cabinet Office under the Atomic Energy Basic Law,consists of five members who are appointed by the Prime Minister with the consent of the Diet. The
chairperson is elected by mutual voting.
The NSC has the duties of planning, deliberation and decisions on matters that are related to ensuringsafety of the utilization of nuclear energy, and establishes guidelines to be used for the safety
examination. If the NSC deems it necessary as part of its assigned duties, the NSC can advise andrequire reporting from the heads of relevant administrative organization by way of the Prime Minister.
Moreover the NSC can require the cooperation such as the submission of reports, statement of views,
explanation etc. against the heads of relevant administrative organization if it is recognized as necessary.
When the regulatory body issues an establishment license for nuclear facility (excluding nuclear fuelmaterial use facility and facility handling RI, etc.) based on the Reactor Regulation Law, the NSC may
independently reexamine and review (what is called “double-checking system”) these validities for theinquiry requested by the competent minister on applicants’ technical ability, the location of relevant
nuclear facilities, and measure for preventing the disaster of its structure and equipment, etc..
E-21

Even in construction and operational stage of the nuclear facility following their approval of licensing,
the NSC receives quarterly reports from the regulatory body on the approval and changes of the
Operational Safety Program, the compliance with the Operational Safety Program by the operator,
results of the Periodical Inspection of Facility, etc. And the NSC independently monitors and reviews
the adequacy of the regulatory activities by directly investigating an operator and a maintenance andinspection operator, if needed.
The NSC has a secretariat in the Cabinet Office. The Secretariat of the NSC is composed of theSecretary-General, the General Affairs Division, the Regulatory Guides and Review Division, theRadiation Protection and Accident Management Division, and the Subsequent Regulation Review
Division, and has about 100 staffs. In the NSC, two Committees for Examination, eight Special
Committees, and two Technical Advisory Bodies and others are organized, as shown in Table E.3-4, anddiscussing the relevant issues.
The special committee can organize, if necessary, the subcommittees under the special committee. The
NSC opens to the public and permits the hearing of all deliberations of the special committees andsubcommittees, and the contents are put under general inspection through the web-site of the NSC(http://nsc.go.jp/) and the Nuclear Energy Library.

Human Resources of a Licence Holder to Maintain Major Nuclear Facilities(1)

Human Resources

When issuing establishment licence of a nuclear facility, the regulatory body confirms that theapplicant possesses technical capability necessary to establish and operate it adequately, except for
the reprocessing activities by JNC and JAERI, two national institutes established by legislation, thenconsults with the NSC (hereinafter called NSC). The NSC established "the Examination Guideline
for the Technical Capability of Nuclear Operators" in May 2004, to conduct examination moreobjectively and rationally. The examination guide defines the technical capability as administrative
capability of an organization to operate its facility and activities ensuring safety, in addition to theknowledge, technologies and skills possessed by the organization. The requirements in this guidelines
are shown in Table F.2-1.
The Reactor Regulation Law provides that the applicant for a license attaches an explanation on its
technical capability to the application format.
The operator of facilities licensed under the Radiation Hazards Prevention Law, before starting theirfacility operation, appoints the Supervisor of Radiation Protection and prepares the Internal Rules forPrevention of Radiation Hazards in which safety management of radioisotopes, work scope andorganization of workers, and education and training programs are provided.

Efforts for Ensuring Infrastructure of Human Resources

Nuclear regulatory bodies and nuclear power industry are making efforts for ensuring human resources
now and in the future.
(1) Training of Experts in NISA
Staff members, who are in charge of nuclear regulation in NISA, are the Nuclear Officer for Nuclear
Emergency, the Nuclear Safety Inspector, the Nuclear Facility Inspector, the Electric Structure Inspector,
and the Safety Examiner. They are referred to as the "Nuclear Regulatory Staffs" hereinafter.
An Officer for Nuclear Emergency is stationed at each nuclear installation, guides and advises thelicense holder in preparing the Operator’s Plan for Emergency Preparedness, and conducts duties
necessary to prevent progression of nuclear emergency should it occur.
A Nuclear Safety Inspector is stationed at each nuclear installation, conducts the Nuclear Safety
Inspection to confirm license holder’s compliance with the Operational Safety Program, addressincidents if they occur, and supervises management for use of a nuclear installation.
A Nuclear Facility Inspector or an Electric Equipment Inspector is dispatched from NISA head office,and conducts inspection activities, such as the Pre-Service Inspection, the Periodic Inspection of a
nuclear installation and the Fuel Assembly Inspection, on the basis of the Reactor Regulation Law or theElectricity Utilities Industry Law, respectively.
Safety Examiners conduct the Safety Examination of a nuclear installation.
A Nuclear Regulatory Staff is required to have expertise in nuclear technology. The system of long term
and multistage education and training programs necessary for improvement of his/her expertise isdeveloped, taking account of his/her experience and of the nature of the facility to which he/she isassigned. Moreover, NISA started a Special Training Course on Quality Assurance of Nuclear
Installation in 2002. Summary of training for nuclear safety regulation is shown in Fig. 11-1.
NISA has appointed six Special Inspection Instructors in December 2003. They advise inspectors for
the Nuclear Safety Inspection, the Periodic Inspection, etc., instruct them to equalize the levels ofinspections, and collect opinions and proposals from inspectors and license holders at the same time.
Furthermore, NISA maintains and develops its regulatory competence, as well as contributes tointernational safety regulation, through exchange of technical experts and information on safety
regulation and safety technology, under bilateral arrangements with foreign regulatory bodies and in the

F-4framework of multilateral cooperation (the IAEA and the OECD/NEA).
(2) Training of Experts in JNESJNES, as well as NISA, develops training courses for its personnel, putting emphasis on inspection
activities.
JNES’s inspection activities include the Electric Equipment Inspection, the Nuclear Facility Inspection,
the Welding Inspection, the Periodic Safety Management Review, the Welding Safety Management
Review, the Safety Verification of Disposal Facility, the Safety Verification of Radioactive Waste
Package, the Verification of Transportation Packaging, the Verification of Transportation Method andVerification of the Clearance Level. The Reactor Regulation Law or the Electricity Utilities Industry
Law stipulates that each of these activities be conducted by qualified personnel. JNES prepares various
training courses for staff members to get appropriate qualification in their respective activities. Presidentof JNES assigns inspectors from those qualified personnel. Moreover, JNES encourages inspectors andexaminers to participate in the school of external bodies, scientific seminars, etc. to enhance theirexpertise.
(3) Efforts by Nuclear Industry
Confronting shrinking and aging population of Japan, the nuclear industry has grave concerns in the
succession of technology, expertise and experiences, and the generational gap. The first generation
experts are in the age of retirement. Each organization in the industry has made various efforts including
revitalization of research and development activity, practical use of IT technology, etc. The Japan
Atomic Industrial Forum, Inc. established the "Subcommittee for Human Resources" consisting ofsenior managers in the industry and experts from outside, and studied on human resources in the future.
The subcommittee has made the following proposals in June 2003:• Training and career development of experts,- Establishment of an industry’s qualification system of nuclear maintenance and repair
technicians- Simplification of organizations of maintenance work
- Establishment of an engineering center to share resources of maintenance and repair

Financial Resources and Financial Rules

In issuing establishment licence of a nuclear facility, except for nuclear fuel material use facility, theregulatory body, in accordance with the Reactor Regulation Law, confirms that the applicant for the
license possesses necessary financial basis, then consults with the AEC.(hereinafter called NSC) The
Reactor Regulation Law stipulates that applicant should submit financial documents attached to theapplication format. For example, an applicant for waste repository should attach such documents as the"Scheduled Date of the Commencement of Operation of Facility and Activities", the "Annual Plan for
Acceptance and Disposal of Radioactive Wastes", the "Financial Plan and Estimated Annual Financial
Balance" and the "Other Financial Matters" to the application format.
Electric utilities have deposited two internal reserves for reprocessing of spent fuel and fordecommissioning, on the basis of the Ministerial Order established under the Electricity Utilities
Industry Law.
The reserve of spent fuel reprocessing will pay for reprocessing expense subtracting the value ofrecovered uranium and plutonium. The amount of reserve by the end of March 2005 is about 3,100
billion yen by 10 electric utilities. As the Law on the Management of the Fund Reserved for Spent Fuel
Reprocessing was enacted in May 2005, the internal reserve of electric utilities is to be transferred to anorganization designated by the Minister of METI.
The reserves for decommissioning of nuclear power generation facilities will pay for the expense of
dismantling and removal of commercial power reactor facilities, and the processing and disposal of thewaste. The amount of reserve by the end of March 2005 is about 1,100 billion yen by 10 electric utilities.
In accordance with the Specified Radioactive Waste Final Disposal Act enacted in May 2000, operatorsof power reactor facilities deposit funds for disposal of high level radioactive waste to the Nuclear Waste
Management Organization of Japan, the implementing body for disposal, who entrusts management of
the fund to the Radioactive Waste Management Funding and Research Center. The Minister of METI,
every year, notifies utilities of the amount of money to be deposited to the fund. The amount of deposit
per vitrified package was 33,964,000 yen in the year of 2004. The amount of money for construction ofdepository in mid-2030s and disposal of about 40,000 vitrified packages of high level waste is estimatedabout 3 trillion yen.
Financial basis of a license holder of fuel material use is to be confirmed through procedures to approve
the Operational Safety Program and the steps to be taken at the time of decommissioning.
Financial basis of the operator of radioisotope waste management facility licensed under the Radiation
Hazards Prevention Law is to be confirmed through the Periodical Inspection, obligation to maintain thefacility in compliance with technical standards, implementation of education and training programs,
notification of the Internal Rules for Prevention of Radiation Hazards and the steps to be taken at thetime of decommissioning.

Quality Assurance (Article 23)

Each Contracting Party shall take the necessary steps to ensure that appropriate quality
assurance programmes concerning the safety of spent fuel and radioactive waste management are
established and implemented.
NISA, recognizing that one of the factors that led to the series of TEPCO falsification issues was
TEPCO’s lack of understanding on the importance of quality assurance system to ensure nuclear safety,
integrated licensee’s QA system into regulatory inspection, by the amendment of the Reactor Regulation
Law enacted in October 2003, and confirms operator’s compliance with it through the Nuclear Safety
Inspection. The quality assurance activities at the major nuclear facilities except for research reactor
facilities and fuel material use facilities, are described in the followings.
F.3.1

Regulatory Requirements on QA of Nuclear Installations

NISA’s regulatory activities on major nuclear facilities, based on the Reactor Regulation Law and theElectricity Utility Industry Law, include licensing, approval of design and construction methods,
pre-service inspection, periodical facility inspection, etc., covering from planning stage to operation
stage. By the Reactor Regulation Law, an operator is required to integrate its quality assurance program
into the Operational Safety Program. NISA approves the Operational Safety Program and confirms theoperator’s compliance with it through the Nuclear Safety Inspection.
The key points of QA activities are as follows.
a) to involve top management,b) to be based on international standards on QA (ISO9001:2000),c) to improve them by Plan-Do-Check-Act cycle, andd) to establish an independent audit organization.
The Reactor Regulation Law stipulates that operator's QA program should include a) organization
managing QA activities, b) plan for operational safety activities, c) implementation of operational safety
activities, d) evaluation of operational safety activities, and e) improvement of operational safety
activities.
Note) The term, operational safety activities, means activities necessary for maintenance of major
nuclear facilities, use of major nuclear facilities, and shipment, storage and disposal of nuclear fuelmaterials or materials contaminated by nuclear fuel materials.
Operators prepare their QA program of the nuclear facilities and implement them, according to JEAC
4111-2003, "Rules of Quality Assurance for Safety of Nuclear Power Plants", which was developed by
the Japan Electric Association (JEA) in autumn of 2003 based on the ISO9001:2000. NISA evaluatedthe standard and confirmed that it meets the regulatory requirements for nuclear facilities other than test
and research reactors and use facilities.
The features of JEAC4111-2003 is as follows.
i)
It is based on ISO 9001:2000, being modified for user-friendliness.
ii) It takes account of IAEA Safety Standards for Quality Assurance 50-C/SG-Q (1996).
iii) The definitions of some terms are different from ISO 9001:2000, based on legal expression innational legislature.
iv) Explanation is added on the terms, "product", "customer", and "quality", in the requirementsof ISO 9000:2000.

F-9

The contents of JEAC4111-2003 are shown in Table F.3-1.
Moreover, NISA is studying to clarify requirements of quality assurance during not only operating stage
but also construction stage in legislation.
F.3.2

Confirmation of Quality Assurance by NISA

(1) Examination of the Policy for QA at operation licensing
NISA requests the applicant to submit the “Policy for Quality Assurance” attached to the application
format, and examines it.
(2) Examination of QA Program in Construction StageAt the construction stage of a commercial power reactor facility, NISA requests the licence holder tosubmit the “Description on Quality Assurance Program” as specified in the Rules for the Electricity
Utilities Industry Law, which describes license holder’s QA activities through detailed design,
manufacturing, installation and functional tests, and examines it. Also, NISA confirms that license
holder of nuclear power reactor oversees subcontractor's quality control, material control, etc. inappropriate procedures, in addition to its QA audit of primary contractor and primary contractor's own
management of manufacturing process.
(3) Confirmation of QA Activities Throughout Service LifeNISA confirms QA activities of the license holder throughout service life of major nuclear facilities
by the Nuclear Safety Inspection. Furthermore, at the commercial power reactor facility, NISA, at the
Periodic Safety Management Review, examines adequacy of operator’s organization and methods for
the Licensee's Periodic Inspection.

exceed national prescriptions for dose limitation which have due regard tointernationally endorsed standards on radiation protection; and(iii)

measures are taken to prevent unplanned and uncontrolled releases ofradioactive materials into the environment.

Each Contracting Party shall take appropriate steps to ensure that discharges shall belimited:(i)to keep exposure to radiation as low as reasonably achievable, economic andsocial factors being taken into account; and(ii)

so that no individual shall be exposed, in normal situations, to radiation doses
which exceed national prescriptions for dose limitation which have due regard tointernationally endorsed standards on radiation protection.

Each Contracting Party shall take appropriate steps to ensure that during the operating
lifetime of a regulated nuclear facility, in the event that an unplanned or uncontrolled releaseof radioactive materials into the environment occurs, appropriate corrective measures are
implemented to control the release and mitigate its effects.
F.4.1

Summary of Laws, Regulations and Requirements on Radiation Protection

The national standards for radiation protection at nuclear facilities are prescribed by the Reactor
Regulation Law, the Electric Utilities Industry Law, the Radiation Hazards Prevention Law, etc. andrelated government ordinances, ministerial ordinances, orders and notifications, and guidelines based onthese laws. The recommendations of the International Commission on Radiological Protection(ICRP) are given due consideration and are incorporated into national legislation and regulation. The
Radiation Review Council coordinates these technical standards in the laws and regulations on
prevention of radiation hazards.
Ministerial ordinances include the Rules for Enrichment and/or Fuel Manufacturing, the Rules forCommercial Power Reactors, the Rules for Reactors at the Stage of Research and Development, theRules for Research Reactors, the Rules for Spent Fuel Storage, the Rules for Spent Fuel Reprocessing,the Rules for Waste Disposal, the Rules for Waste Management and the Rules for Fuel Material Use on
the basis of the Reactor Regulation Law, and the Rules for the Enforcement of the Law Concerning
Radiation Hazards Prevention and other rules on the basis of the Radiation Hazards Prevention Law.
These regulations prescribe area control for radiation protection, radiation control of personnel engaged
in radiation activities in controlled areas, measurement and surveillance of radiation levels, monitoringof discharged radioactive materials, and maintenance of radiation control equipment. The Notification
for Dose Limits on the basis of each of these rules prescribes dose limits and concentration limits ofradioactive materials both inside controlled area and outside peripheral monitoring area, and dose limits
and concentration limits of radioactive materials for personnel engaged in radiation work, and dose
limits for personnel engaged in emergency activities.
In order to ensure compliance with these regulations, operators are required to prescribe in the
Operational Safety program, 1) controlled areas, access controlled areas and peripheral monitoring area
F-11and access control to these areas, 2) monitoring equipment at air ventilation and water discharge, 3)
monitoring of dose, dose equivalent, concentration of radioactive materials in the air and density ofradioactive materials on the surface of contaminated objects, and the decontamination, and 4)
maintenance of radiation monitoring equipment. In examining application of a license for a nuclear
facility, it is confirmed that the application conforms to the Examination Guides established by the NSC
as well as the legislation and technical standards. In these guides, operators are required to reduce theradiation dose received by the public in the vicinity of the facility site as low as reasonably achievable.
F.4.2

National Requirements on Radiation Protection and the Implementation(1) Allowable Dose Limits
1) Definition of Controlled Areas
The abovementioned rules and dose limit notifications define a controlled area as an area where
dose of external radiation may exceed 1.3mSv for a period of three months, the concentration ofradioactive material in the air, excluding natural background, may exceed the limit specified in
the notification, or the density of radioactive material on the surface of contaminated objects
may exceed the limit specified in the notification, and request operators to take necessary
measures in the area.
2) Allowable Dose Limits for Occupational Exposure
The abovementioned rules and dose limit notifications provide for the allowable dose limits foroccupational exposure listed in Table F. 4-1.

At major nuclear facilities licensed on the basis of the Reactor Regulation Law, operators are required
to keep the radiation dose received by the public in the vicinity of the facility low taking the ALARA
principle, in addition to comply with dose limits and concentration limits of radioactive materials
outside peripheral monitoring area due to the discharge of radioactive wastes.
For nuclear power reactors, the guidelines prepared by the NSC, "the Guidelines for the Dose Target
Value in the Vicinity of the Light Water Nuclear Power Reactors", defines the target value forradiation doses received by the public in the vicinity of the facilities as 50 μSv per year due to therelease of radioactive materials to the environment during normal operation. Operators establish theannual numerical discharge control guide that satisfies the above-mentioned target, put it in the
Operational Safety Program, and obtain approval of the regulatory body.
For the reprocessing facility, fabrication facility, use facility, waste disposal facility, and waste
management facility, the operators are required to reduce radiation doses based on the ALARA
principle at the license examination. Operators define the control target value smaller than the dose
limit of 1 mSv / year, put it in the Operational Safety Program, and obtain approval of the regulatory
body. During the decommissioning, operators continue the radiation control, setting the control target
value equivalent or lower than the value during operation.
The regulatory body approves the control target value, confirms compliance with the Operational
Safety Program, and collects report from operators.
At radioisotope waste management facilities licensed on the basis of the Radiation Hazards
Prevention Law, an operator, in addition to comply with concentration limits of gaseous and liquid
discharge, makes efforts to keep dose at site boundary below 250 μSv / 3 months(3) Measurement of Environmental Radiation
An operator of major nuclear facility licensed on the basis of the Reactor Regulation Law conducts
radiation monitoring at the site vicinity during normal operation, assesses the impact upon theenvironment of the discharge of radioactive materials from the facility, and feedbacks the results inimproving discharge control and facility management.
Local governments hosting nuclear facilities also monitor radiation level independently at the site
vicinity to protect public health and safety.
Meanwhile, the NSC indicates fundamentals of the monitoring plan and its implementation and theevaluation of radiation dose in the Guide on Environmental Radiation Monitoring, in order toimprove and standardize monitoring technology. Local governments and operators implementmonitoring in accordance with the guide.
An operator of radioisotope waste management facility licensed on the basis of the Radiation Hazards
Prevention Law monitors radiation level and measures contamination by radioactive materials at
controlled area boundary, site boundary and any appropriate points.

F-13

F.4.3

Regulatory Control Activities(1) Discharge Control of Radioactive Materials
The abovementioned rules provide that three-month-averaged concentration of radioactive materials
in air outside peripheral monitoring area shall not exceed the concentration limits for discharge ofgaseous radioactive waste, that three-month-averaged concentration of radioactive materials in waterat the outside of the boundary of the peripheral monitoring area shall not exceed the concentration
limits for discharge of liquid radioactive waste with a discharge facility, and that doses due to liquid
discharge of radioactive wastes from reprocessing facilities monitored at the outlet to the ocean shallnot exceed the dose limit. The rules also provide that operators shall immediately report to thecompetent minister when any of these limits are exceeded, and report within 10 days on details of theevent and corrective measures taken.
(2) Control of Personal Exposure
The abovementioned rules require operators to keep records of doses to personnel engaged inradiation work.
F.4.4

Unplanned or Uncontrolled Releases

Operators of Nuclear Facilities, on the basis of abovementioned rules, shall prepare the Operational
Safety Program and have them approved by the regulatory body, which provide that operators, in case of
unplanned or uncontrolled release of radioactive materials, should take measures against the spread ofcontamination by nuclear fuel materials or radioisotopes and carryout decontamination work without
delay.
And as an example, the Safety Examination Guide for Reprocessing Facility, which is used in safety
examination of reprocessing facility with large inventory of radioactive materials, provides that fire andexplosion due to fine metal particles from fuel cladding or organic solvent, criticality accident, leakage
or loss of function due to damage or failure of equipment or piping, or spent fuel handling failure do notcause excessive exposure of radiation to the public.
When an unplanned or an uncontrolled release of radioactive materials initiates any specific events(Table F.5-1) defined in the Specific Law for Nuclear Emergency, emergency activities start according
to the procedure, and the Prime Minister declares Nuclear Emergency if the initial event progresses andexceeds the predetermined level. Nuclear emergency will be described in detail in the ensuing section.

F.5

Emergency Preparedness (Article 25)
1.

Each Contracting Party shall ensure that before and during operation of a spent fuelor radioactive waste management facility there are appropriate on-site and, if
necessary, off-site emergency plans. Such emergency plans should be tested withappropriate frequency.

2.

Each Contracting Party shall take the appropriate steps for the preparation andtesting of emergency plans for its territory insofar as it is likely to be affected in theevent of a radiological emergency at a spent fuel or radioactive waste management
facility in the vicinity of its territory.

F.5.1

Laws, Regulations and Requirements for Nuclear Emergency Preparedness

The JCO Criticality Accident in September 1999 was a very serious accident when local residents were
instructed for sheltering or evacuation for the first time in Japan, shattering basic premise of securingsafety in promoting utilization of nuclear energy. Lessons learned from the accident clarified the special
characteristics of nuclear emergency, which would demand quick initial response, coordinatedcooperation among the national and local governments, strengthening of the national emergency
preparedness and the clarification of operator’s responsibilities. The Specific Law for Nuclear
Emergency Preparedness (hereinafter referred to the Specific Law for Nuclear Emergency) was enacted
in December 1999 and enforced in June 2000, addressing the special characteristics of nuclear
emergency (note 1) mentioned above. The law was enacted within the legal framework alreadyestablished by the Basic Law on General Emergency Preparedness, which had defined roles of thenational government, local governments, etc. in emergencies such as earthquakes, typhoons,conflagrations and nuclear emergency.
The part of “Nuclear Emergency Preparedness” in the Basic Plan for Emergency Preparedness based on
the Basic Law on General Emergency Preparedness, was extensively revised in accordance with theSpecific Law of Nuclear Emergency, clarifying roles and responsibilities of the national government,
local governments, and nuclear operators (note 2).
The NSC, taking into consideration the Specific Law for Nuclear Emergency and the lessons learned
from the JCO Criticality Accident, revised the Emergency Preparedness Guidelines on technical andspecialized matters for nuclear emergency in May 2000,-

to expand the scope for research reactors and nuclear fuel related facilities in addition to the
nuclear power stations, reprocessing facilities, etc., andto include measures against the nuclear fuel material release and the nuclear criticality
accident in addition to the noble gases and iodine release.

After that, the guidelines has been revised several times by the NSC,-

to amend the terms and the coefficient of dosage (Sv/Bq) for internal exposure, following
the integration of ICRP1990 recommendations into national legislation (March 2001),
to clarify responsibilities of medical professionals of the national government, local
governments, operators, etc. feeding back the experience of medical treatment at thecriticality accident (June 2001),
to amend measures of the preventive use of stable iodine tablets taking account ofscientific knowledge acquired by the long-term follow-up survey on atomic bomb
survivors and the investigation into the Chernobyl accident (April 2002),
to define the measures of the mental health at a nuclear emergency, taking account of the

F-15

-

experiences at the criticality accident and at natural disasters such as seismic hazards(November 2002), andto define local plan for the emergency medical treatment system (July 2003).

In this section, emergency preparedness of main nuclear facilities in accordance with the Specific Lawof Nuclear Emergency is described.
note 1) The term “nuclear emergency” means unusual release of radioactive materials or unusual
radiation streaming outside of a nuclear facility, by operation of a nuclear reactor, fabrication,
reprocessing and use of nuclear fuel materials, storage of spent fuels, management of nuclear fuelmaterials or the materials contaminated with nuclear fuel materials, and the accompanying
shipment, and the term “nuclear disaster” means the damage caused by a nuclear emergency to thelife, health or property of the public, according to the Specific Law of Nuclear Emergency.
note 2) The term “an operator” means a license holder for fuel manufacturing operation of nuclear
reactors, spent fuel storage , reprocessing , radioactive waste disposal , or use of nuclear fuelmaterials, according to the Specific Law of Nuclear Emergency.
F.5.2

Nuclear Emergency Preparedness and the Emergency Measures

The nuclear emergency preparedness and the emergency measures concerning operators and major
nuclear facilities in accordance with the Specific Law of Nuclear Emergency are as follows.
(1) Outline of Nuclear Emergency Preparedness at Major Nuclear Facilities (Fig. F.5-1)
Quick response and coordinated cooperation among related organizations are important in a nuclear
emergency.
- The Specific Law of Nuclear Emergency defines specific initial events in a major nuclear
facilities (see Table F.5-1), the occurrence of which the operator shall immediately notify
the competent minister and the heads of related local governments of.
- The competent minister, receiving the notification, starts activities according to theprocedure stipulated by the law. Staff with expertise in emergency measures will be sent tolocal governments on request. The Senior Officer for Nuclear Emergency collects
information and coordinates activities preventing expansion of the events.
- When the competent minister recognizes that the specific initial event exceeds thepredetermined level and has developed into an emergency, the minister immediately reports
it to the Prime Minister.
- The Prime Minister declares “Nuclear Emergency”, and advises or directs related local
governments on necessary measures such as sheltering, evacuation or preventive use of
stable iodine tablets to be taken by them.
- The Prime Minister establishes the "Nuclear Emergency Response Headquarters" in Tokyo,
which he will head, and the "Local Nuclear Emergency Response Headquarters".
- The NSC, when a nuclear emergency occurs, calls the Emergency Technical Advisory Body
that consists of members from the NSC and the Investigation Committee for Emergency
Measures and makes technical advices to the Prime Minister.
- Local governments establish their own emergency response headquarters.
- The national government, local governments and related operators etc. establish the "Joint
Council for Nuclear Emergency Response" at the Off-Site Center in order to share
information and coordinate their emergency measures.
(2) On-site and Off-site Nuclear Emergency Preparedness at Major Nuclear Facilities
Organizations related to nuclear emergency preparedness keep themselves always ready to collectand send information and start quick response against an emergency, and conduct exercises,

Decommissioning (Article 26)

Each Contracting Party shall take the appropriate steps to ensure the safety ofdecommissioning of a nuclear facility. Such steps shall ensure that:(i)qualified staff and adequate financial resources are available;(ii)

the provisions of Article 24 with respect to operational radiation protection,discharges and unplanned and uncontrolled releases are applied;(iii) the provisions of Article 25 with respect to emergency preparedness are applied;and(iv) records of information important to decommissioning are kept.

The AEC’s Long-term Program states that nuclear facilities licensed on the basis of the Reactor
Regulation Law should be decommissioned safely at the responsibility of their operators, with theunderstanding and support of the local community, and that the land, after decommissioning ofcommercial power reactors, is expected to serve as sites for new nuclear power plants again with theunderstanding of their communities.
The regulatory policy for dismantling or decommissioning of reactor facilities has been investigated anddiscussed, resulting as following three reports;(1) "Basic Philosophy to Assure Safety for the Dismantling Nuclear Reactor Facilities" (December
1985, Decision by the NSC, revised in August 2001),(2) " Aiming at Decommissioning of Commercial Nuclear Power Facilities " (January 1997, Nuclear
Energy Subcommittee, Advisory Committee for Natural Resources and Energy ),(3) "Philosophy for Safety Assurance and Safety Regulation on the Decommissioning of Commercial
Power Reactor Facilities" (August 2001, Decommissioning Safety Subcommittee, Nuclear andIndustrial Safety Subcommittee, Advisory Committee for Natural Resources and Energy).
Based on these reports, in order to ensure the safety during the decommissioning of commercial nuclear
power reactors, the regulation was implemented by applying existing provisions in the Reactor
Regulation Law, such as “notification of dismantling” or “modification of Operational Safety Program,by the operators.
So far, the decommissioning of reactor facilities was implemented at the Power Demonstration Reactorof the Japan Atomic Energy Research Institute (JPDR) and the Tokai Power Station of Japan Atomic
Power Co. Inc., etc. and the development and application of dismantling technologies have been
progressed, and the know-how for decommissioning have been accumulated through these processes.
Under such a circumstance, in October 14, 2004, the NSC pointed out, that “it is required to investigate
the development of a graded approach in safety regulation system to cope with the progress of
dismantling processes, as the main activities during the period after the cease of operation are safety
management of spent fuels, dismantling works and the radiation control, and handling of radioactive
wastes, and the regulatory experiences concerning dismantling and decommissioning of test andresearch reactors have been accumulated”, as the conclusion of the regulatory activities investigation
concerning the safety regulation system during the period after the cease of operation of reactor
facilities.
The Decommissioning Safety Subcommittee has investigated appropriate regulatory system ofdecommissioning, based on the regulatory experiences on decommissioning of reactor facilities under
the current system, aiming for amendment of legislations, with the principle of ensuring safety.
The investigation is conducted from view points of ensuring transparency of regulations, and gradedregulatory approach to cope with the progress of the decommissioning process, the diversity of eachfacilities, reflecting the experiences of decommissioning, and development of technology in the near
F-25

future, and reported in "The Way of the Decommissioning Regulation of the Nuclear Facilities"(December 9, 2004)).
In this investigation, the Subcommittee recognized that the decommissioning of nuclear reactors is
becoming to a routine, and the amendment of legislation must cope with graded approach by regulatory
body and clarification of the responsibilities of operators with the principle of ensuring safety, and it isconsidered to be important (i) to clarify the requirement in decommissioning regulations, (ii) to keep thetransparency on procedures for the operators, and (iii) to obtain in the understanding and confidence ofthe national people and local residents on decommissioning regulations.
The Subcommittee proposed the way of decommissioning regulations, as;(1) replacing “dismantling notification by operator”, to the “approval of the operator’s
decommissioning plan of dismantling processes, methods etc. by regulatory body “,(2) implementation of the decommissioning as approved in the plan,(3) completion of decommissioning is confirmed by regulatory body(4) After the confirmation of the completion of decommissioning, operator can dismiss the operation
license(5) the regulatory activities during the decommissioning process ( example: Periodical Inspections,
Nuclear Safety Inspections etc.) should be changed in accordance with the changes of the functionsof the facilities and safety operation activities as the decommissioning is proceeded ( gradedregulatory approach)In the proposal, it is stated that
(1) The operator apply the decommissioning plan including process of decommissioning, methods of
dismantling, method of managing the radioactive waste generated during the dismantling, the safety
analysis, financial plan.
(2) Regulatory body review the plan on the conformity with technical criteria and approve it.
(3) The operator conduct the decommissioning in accordance with the decommissioning plan, usually
the decommissioning takes a long time and consists of several steps, it is allowed to modify the
program at the beginning of each step with the prospect that the completion of decommissioning isensured, following the approval for the modification of decommissioning plan.
The amendment of the Reactor Regulation Law was enacted in May 2005, along with the proposal, andthe associated detailed provisions are under preparation.
F.6.1
(1)

Human and Financial Resources
Human Resources

Operators clarify, in the Operational Safety Program, safety organizations, responsibility and roles indecommissioning processes, and planning and implementation of relevant safety education programs
necessary for managers and workers including subcontractors.
The regulatory body confirms the observance of the above-mentioned Operational Safety Program by
the inspection (Nuclear Safety Inspection).
(2)

Financial Resources

Electric utilities have deposited funds for decommissioning of commercial power reactor facilities
using the Dismantling Reserve Funds.

F.6.2

Radiation Protection at the Decommissioning Stage

The regulations on radiation protection applied to nuclear facilities in operation, which is described at
Article 24 (Section F.4), are also applicable to nuclear facilities in the process of being decommissioned.

F-26

F.6.3

Emergency Preparedness

The regulations on emergency preparedness applied to nuclear facilities in operation, which is describedat Article 25 (Section F.5), are also applicable to nuclear facilities in the process of being
decommissioned.
F.6.4

Keeping Records of Information Important to Decommissioning

The Reactor Regulation Law requests to keep important records such as inspection records, radiation
control records, etc. even at decommissioning stage.
And other records specific to decommissioning such as each equipment or system being dismantled,schedule and method for dismantling it, etc. are required to be recorded and kept at the end of eachdismantling process. .
Thus the regulatory body can confirm that the decommissioning has been appropriately completed
ensuring safety and in compliance with the Decommissioning Plan of that facility by keeping records toshow it.

G. Safety of Spent Fuel Management

Blank Page

Section G. Safety of Spent Fuel Management
The safety of spent fuel management is ensured in accordance with the regulatory framework explainedin Section E.2.3. In other words, the safety management of spent fuel on a reactor facility site or a
reprocessing plant site is regulated by the provisions of the Reactor Regulation Law concerning theestablishment and operation of nuclear reactors or a reprocessing facilities. More specifically, spent fuelmanagement facilities are regulated as associated facilities operated in the respective reactors or
facilities. On the other hand, the safety management of spent fuel stored outside a reactor or a
reprocessing plant site is regulated in accordance with the provisions for storage in the Reactor
Regulation Law, and is regulated as specialized facilities concerning licensing, permission, approval andinspections. At present, there is no storage facility which is in operation, under construction or forwhich an application for licensing of construction has been filed.
Present regulations have been established assuming storage of spent fuels in water pools or metal drycasks at the sites of nuclear reactor facilities, in water pools at the sites of reprocessing facilities, and inmetal, or concrete, dry casks at the specialized storage facilities.
Figure G.1 outlines the regulatory process concerning spent fuel storage facilities in comparison with thejoint convention. A flow of regulations begins with an application for a license. The regulatory body
grants an operator of a license for storage facility after the Safety Examination. Prior to construction of
the installation, the regulatory body examines design and construction plan and approves them if they
are acceptable. When construction of the facility requires prescribed welding process, the regulatory
body confirms it through the Welding Inspections or the Welding Safety Management Inspections.
Moreover, the regulatory body conducts the Pre-Service Inspections to make sure that the construction
works are being carried out in accordance with the approved design and construction plan. The
regulatory body requires the operator to establish the Operational Safety Program and approves it. The
operator starts operation of the facility (excluding reactor facilities), after notifying the regulatory bodyof it.
After the facility started operation, the regulatory body conducts the Periodical Inspection of Facility toconfirm the integrity of the facility, and the Nuclear Safety Inspection to confirm the operator’scompliance with the Operational Safety Program.
The operator starts decommissioning after preparing a decommissioning plan describing thedecommissioning processes, the financial plan, etc. and obtaining approval of it by the regulatory body.
Decommissioning procedure finishes when the regulatory body confirms completion of the dismantling.

Consideration of Biological, Chemical and Other Hazards

The regulatory body, when issuing license to a major nuclear facility in accordance with the Reactor
Regulation Law, conducts the Safety Examination to ensure that the location, structure and equipment of
the facility are adequate to prevent hazards due to nuclear fuel material or materials contaminated by it.
G.1.6

Consideration of Impacts on Future Generations

As mentioned in Section B, the Government of Japan makes it a basis of its nuclear energy policy toestablish a national nuclear fuel cycle in which spent fuel is reprocessed in order to make effective use of
uranium resources. Spent fuel generated by nuclear power plant is considered as a useful recyclable fuelresource, so that it will be stored and managed safely until it is reprocessed.
G.1.7

Consideration of Burdens on Future Generations

The competent minister is required by the law to examine license application for a major nuclear facility
to ensure that issuing license does not pose any impediment to the development and planned utilizationof nuclear energy and that the applicant has a financial basis necessary for adequate operations.
Also, a reserve for reprocessing spent fuels is provided as described in F.2.3.

Table G.1-1 Examples of Requirements Concerning the Criticality and Residual Heat Removal
Described in the Safety Examination Guidelines
for the Spent Fuel Interim Storage Facility Using Metal Dry Casks
Guideline 8. Consideration for long-term storage etc.
The spent fuel interim storage facility should be designed to maintain the integrity of spent fuelassemblies and the integrity of the components that have fundamental safety functions throughout
the design storage period by taking the following measures, in considerations of degradation etc.
accompanied by the long-term storage.
1. Components of metal cask important to maintain fundamental safety functions should bedesigned not to loose required safety function maintaining required strength and performanceby selecting materials that have sufficient reliability in the environments such as temperatureand radiation during design storage period and to the degradation such as corrosion, creeping,and stress corrosion cracking under the above environments.
2. The metal cask should contain and sore the spent fuel assemblies together with sealing inert
gases.
3. The metal cask should be designed to be able to remove the decay heat from spent fuels in viewof maintaining the integrity of spent fuel assemblies and the integrity of the components thathave fundamental safety functions.
4. The storage building should be designed to be able to maintain the room temperature in thebuilding low in view of the heat removal from the surface of a metal cask. And, it should bedesigned to be able to monitor that the room temperature in the storage building will not elevateto the unusual level.
Guideline 10. Criticality safety of a single metal cask
A single metal cask in the spent fuel interim storage facility should be designed to prevent thecriticality in any case technically assumable under the condition that spent fuel assemblies arecontained in the cask.
In case the internal basket shares the criticality prevention function, the metal cask should bedesigned to maintain the temperature within the range to keep the structural integrity of the basket
throughout the design storage period.
Guideline 11. Criticality safety of multiple metal casks
The spent fuel interim storage facility should be provided with measures to prevent the criticality
in any case technically assumable considering the neutron interference among metal casks in thefacility.
Guidelines 12. Consideration for nuclear criticality accidents
In case a nuclear criticality accident could occur by operational error etc. at the spent fuel interim
storage facility, appropriate measures for the unlikely event of nuclear criticality accident shall betaken.
However this guideline may not be applied in case of Guideline 10 and Guideline 11 areconformed and spent fuels are contained in the metal cask, since criticality could not physicallyoccur.

The regulatory body, when issuing a license to operate a nuclear facility in accordance with the Reactor
Regulation Law, conducts the Safety Examination to ensure that siting and basic design of facility,
equipments and components of a major nuclear facility are adequate to prevent hazards due to nuclear
fuel material or materials contaminated with it. The Safety Examination Guidelines, used in the Safety
Examination, require to evaluate external events at the site and its periphery of the proposed facility, andto evaluate radiological impacts to the public caused by the facility.
Examples of requirements in the Safety Examination Guidelines for Spent Fuel Interim Storage Facility
Using Metal Dry Casks are shown in Table G.3-1.
G.3.2

Information Disclosure

Information on the safety of nuclear facilities, including application documents, is made available to the
public at the Nuclear Energy Library and the Library of JNES. Moreover, the Public Information Law,
enacted on April 1, 2001, provides for disclosure of administrative documents on request with some
exception.
Furthermore, application documents submitted by applicants for licenses are disclosed for the public at
the National Diet Library.
G.3.3

Relationship with Neighboring Countries

Being an insular country, Japan is located at a considerable distance from its neighboring countries.
Therefore, as long as the safety of nuclear facilities is properly secured within Japan, nuclear facilities in
the country are unlikely to have safety impacts on the neighboring countries. The Japanese government
does not have it a rule to consult the neighboring countries about siting of nuclear facilities. The
Japanese government provides neighboring countries with information on nuclear energy throughbilateral consultation, etc.

environment of the site, and safety design of the facility, and examine them.
The Safety Examination Guides, used to examine an application documents, require the applicant toperform safety assessment on the maximum postulated accidents in each nuclear facilities prescribed in
the guides, and confirm that these accidents do not cause excessive public exposure of radiation.
The Safety Examination Guides require operators of reactor facilities and reprocessing facilities, whichcontain large quantities of radioactive material, to perform both safety design assessment to confirm theadequacy of safety design of the facility, and siting assessment to assess the isolation of the facility fromthe public considering radiological hazards. In the safety design assessment, the guides require that
postulated drop of a fuel assembly, in a water-pool-type spent fuel management facility attached to a
power reactor facility, does not cause excessive public radiation exposure.
G.5.2

Updating of Assessments Before Operation of Facilities

The Reactor Regulation Law provides that nuclear operators shall apply for alteration of license, when it

G.6.1

Verification through Pre-service Inspection

An operator, in accordance with the Reactor Regulation Law or the Electric Utilities Industry Law,
prepares the Construction Plan and submits it to the regulatory body for approval. Also, the operator
undergoes the Pre-Service Inspection by the regulatory body at each construction process and at the endof all construction works, to verify that the construction is completed as approved and is consistent withthe technical standards. Passing Pre-service inspections, the nuclear operator is allowed to commence
operation of the facility.
G.6.2

Operational Requirements and Conditions

Before the operation of a nuclear facility, an operator, in accordance with the Reactor Regulation Law,
notifies the regulatory body of an Operational Plan and prepares the Operational Safety Program,specifying methods of operation, inspection, radiation monitoring, quality assurance etc. and submits itto the regulatory body for approval. The Operational Safety Program shall specify operational limits,and the facility shall be operated and maintained in compliance with the program. Table G.6-1 shows thecontents of the Operational Safety Program of the spent fuel interim storage facility. The competent
minister, finding noncompliance with the operational requirements, orders the operator to takecorrective measures.
An operator assigns a Chief Engineer of Reactor, a Supervisor of Nuclear Fuel Material or a Supervisorof Spent Fuel, who has passed national examinations, and is put in charge of overseeing safety in theoperation of the nuclear facility.
G.6.3

Procedures and Conduct of Maintenance, Operation, Inspection, etc.

In accordance with the Reactor Regulation Law or the Electric Utilities Industry Law, operators, after

G-15

commencement of the operation of nuclear facilities, are required to undergo the Periodical Inspectionof Facility and the Nuclear Safety Inspection.
(1) Periodical Inspection of Facility
The regulatory body conducts the Periodical Inspection of Facility once a year (once every 13 months
in the case of commercial power reactor facilities) to see whether performance of the facilities andequipment complies with the technical standards prescribed by laws and ordinances.
(2) Nuclear Safety Inspection
The regulatory body stations a Nuclear Safety Inspector to each nuclear facility to conduct the
Nuclear Safety Inspection four times a year to confirm operator’s compliance with the Operational
Safety Program and disclose the results to the public.
G.6.4

Technical Support throughout the Operation Lifetime

Throughout the operational lifetime of a nuclear facility, the regulatory body obtains engineering andtechnical advice from a committee, which is composed of experts on operational management,
inspection and radiation control, and reflects it in the operation, maintenance and safety regulations asnecessary.
METI promotes reliability test projects of main equipment and components, as well as various safety
research programs. MEXT promotes safety research programs as part of nuclear science research.
Nuclear facility operators collect information on operating experience both domestic and abroad, andaccumulate up-to-date technical information through their own development projects of technology andrepair work.
Regulatory bodies and operators may obtain various technical supports from private institutes andorganizations.
G.6.5

Reporting of Incidents and Failures

The Reactor Regulation Law or the Electric Utilities Industry Law requires operators to report to theregulatory body on incidents or failures at major nuclear facilities and measures taken against them. The
reporting criteria prescribed in these laws for the spent fuel interim storage facility are shown in Table
G.6-2. The regulatory body assesses the accident or failure using the International Nuclear Event Scale(INES) since August 1992. The regulatory body encourages operators to disseminate among themmeasures taken against incidents or failures to prevent recurrence.
G.6.6

Reflecting Operating Experience

Upon receipt of a report on an incident or a failure at a nuclear facility, the regulatory body immediately
makes it public, and discloses the cause of it and measures to prevent recurrence when they are clarified.
The regulatory body assesses each incidents or failures in detail to obtain lessons ensuring safety,
soliciting advice from committee composed of experts on operation management, inspection andradiation control, and makes them reflected in the operation, maintenance and safety regulations as
appropriate.
Supporting organizations to the regulatory bodies collect and analyze information on operating

G-16

experience of both domestic and foreign nuclear facilities, and provide information to relatedorganizations. For example, JNES, a supporting organization to NISA, establishes a system to collectand analyze domestic and foreign information and reports the results promptly to NISA. NISA and
JNES jointly established the “Safety Information Study Committee” to study information periodicallyand decide appropriate regulatory response and follow-up.
A mechanism is established to exchange information about incidents and failures through internationalorganizations such as the IAEA and the OECD/NEA, as well as under bilateral cooperation agreements.
Electric utilities, as well as the Central Research Institute of Electric Power Industry (CRIEPI), collectand analyze both domestic and overseas information on operating experiences, and have established“NUCIA” (NUClear Information Archives), a tool to share information with the public, which isoperated on the Internet (http://www.nucia.jp/) since October 2003. Electric utilities exchange
information on operating experience with overseas utilities through the Institute of Nuclear PowerOperations (INPO) and the World Association of Nuclear Operators’ (WANO) Tokyo Center. Also,
some electric utilities have information exchange agreements with electric utilities and reactor
manufacturers in France, Germany, the United States, etc. Recognizing the importance of safety
information sharing and safety culture throughout the nuclear power industry, related organizations
jointly established a private institute “the NS Net” in December 1999. The NS Net performs peer review
and other routine activities. The NS Net was merged into the Japan Nuclear Technology Institute(JANTI), which took over activities of the NS Net since April 2005, .
G.6.7

Decommissioning Plans and Updating of Information

As described in Section F.6, operators shall submit decommissioning plan describing dismantling
method, disposal of nuclear fuel materials and articles contaminated by them, safety assessment,
financial plan, etc. to the competent minister, and obtain approval of it. The operator conducts
decommissioning in accordance with the approved plan. However, in order to make long term regulation
more effective, the regulatory body allows operators to submit detailed plan for each decommissioning
process just before start of the process concerned, through the application of alteration of the original
plan.

H. Safety Radioactive Waste Management

Blank Page

Section H. Safety of Radioactive Waste Management
Safety of Radioactive waste management is ensured under the regulatory framework described in
Section E.2.4. The management of radioactive wastes generated from fuel fabrication facilities, reactor
facilities, reprocessing facilities etc. are regulated by the respective provisions in the chapters forcorresponding respective facilities of the Reactor Regulation Law. The management of radioactive
wastes generated from radioisotope use facilities, etc. is regulated by the Radiation Hazards Prevention
Law.
The Reactor Regulation Law has provisions in corresponding chapter for the waste management
facilities and activities which are divided to two categories. One is a waste disposal in near surface andintermediate depth repository and the other is a treatment and storage of radioactive wastes. The
Radiation Hazards Prevention Law has provisions for the waste management services, which deal with
repackaging, storage and near surface disposal of wastes.
The Reactor Regulation Law also provides that the radioactive wastes generated from a nuclear facility
should be treated and stored inside the facility. High-level radioactive wastes(HLW) generated bycontracting overseas reprocessing of Japanese spent fuel are returned to Japan and stored at theradioactive waste management facility of the Japan Nuclear Fuel Ltd. LLW generated by the
reprocessing at overseas are also to be returned to Japan in the future.
In regard to the geological disposal of, HLW, safety regulations etc. are under development, and theopen solicitation of candidate site for safe disposal of HLW for survey that is the first stage of selection
process of the potential site is carrying out by Nuclear Waste Management Organization of Japan, in
accordance with the procedure subscribed in the “Specific Radioactive Waste Final Disposal
Act”(2000).
In regard to disposal of LLW, applicable laws and regulations have been prepared and the disposal has
been under way. For some of LLW, and for some of the other LLW, they are subject to future
development (Table B.3-2). This section describes about the regulations for the LLW, for which
disposal is going on, especially for wastes with relatively lower or very low level radioactive waste.
Figure H.1 outlines the procedure of regulation on the near surface disposal of LLW generated fromoperation of nuclear reactor facilities in terms of the convention. The figure deals with both cases ofwastes disposal, one with waste disposal of relatively lower radioactivity level and solidified in drum
and disposed in a repository with engineered barriers such as concrete pits and the other with very low
level radioactivity not solidified in drum and disposed in a repository without engineered barriers.
The former is a repository of the Low-Level Radioactive Waste Disposal Center of the Japan Nuclear
Fuel Limited established in Rokkasho-mura in Aomori prefecture. As a case of latter is a disposal
facility of Japan Atomic Energy Research Institute(JAERI), Tokai-mura, Ibaraki prefecture as ademonstrative on-site disposal experiment, where concrete wastes generated from dismantling of theJapan Power Demonstration Reactor(JPDR) of the JAERI have been disposed of.
The regulatory procedure starts with an application of a license by a waste disposal facility operator. The
regulatory body carries out necessary examination and issue the license when the application is
conformed with the regulation. The regulatory body confirms that the waste disposal facility and thesafety operation measures to be taken are in compliance with the technical standards provided in theReactor Regulation Law. After the confirmation by the regulatory body, the operator submits a notice ofthe start of operation and then starts operation.
After the start of operation, the regulatory body conducts the nuclear safety inspection four times a year.
Other than this inspection, it conducts the confirmation prior to the disposal of waste packages that thewaste packages are in compliance with technical criteria provided in the Reactor Regulation Law
H-1

(Safety Verification of Radioactive Waste Packages).
After completion of emplacement of waste packages in the repository, the open space between andsurrounding the packages is filled with mortar as monolith in order to avoid leaving any voids. The
repository is then covered its surface with soil. The regulatory body confirms that the cover with soil isin compliance with technical standards for waste disposal facilities etc. (Safety Verification of Disposal
Facility).
The guides of the NSC “Fundamental Guidelines for Licensing Review of Land Disposal Facility of
Low-Level Radioactive Waste” (issued in March 17, 1988, Partial revisions on January 7, 1993 andMarch 29, 2001) describes that stepwise management is applied to the waste disposal site until theradioactivity level become lower than the level on which the safety concern becomes negligible due todecay of radio-nuclides in the disposed wastes. The details of the management of the repositories withand without engineered barriers differ each other. The institutional control after closure of the repository
can be terminated within a reasonable time period, provided that expected public exposure after the period dueto the wastes disposed of can be such a low level as does not need any management for radiation control. At
the end of the institutional control, the operator shall submit the notice of the termination of the license.

General Safety Requirements (Article 11)

Each Contracting Party shall take the appropriate steps to ensure that at all stages ofradioactive waste management individuals, society and the environment are adequately
protected against radiological and other hazards. In so doing, each Contracting Party shalltake the appropriate steps to:(i)ensure that criticality and removal of residual heat generated during
radioactive waste management are adequately addressed;(ii)

ensure that the generation of radioactive waste is kept to the minimum
practicable;(iii)

take into account interdependencies among the different steps in radioactive
waste management;(iv)

provide for effective protection of individuals, society and the environment, byapplying at the national level suitable protective methods as approved by theregulatory body, in the framework of its national legislation which has due
regard to internationally endorsed criteria and standards;(v)take into account the biological, chemical and other hazards that may be
associated with radioactive waste management;(vi)

strive to avoid actions that impose reasonably predictable impacts on future
generations greater than those permitted for the current generation;(vii) aim to avoid imposing undue burdens on future generations.

H.1.1

Prevention of Criticality and Removal of Residual Heat

The regulatory body, when issuing a license in accordance with the Reactor Regulation Law, conducts alicensing review to ensure that the location, structure and equipment of a nuclear facility are adequate toprevent radiation hazards caused by nuclear fuel material or matters contaminated by it.
In the licensing review of a radioactive waste management facility, the regulatory body confirms that theappropriate measures are taken to prevent criticality and remove residual heat. The Rules for
Reprocessing for Spent Fuel and the Rules for Management of Waste of Nuclear Fuel Materials or
Those which are Contaminated Therewith provide that necessary measures for cooling should be taken
when the fear for a significant over heat due to decay of radio-nuclides is anticipated or a report should
be made when the fear for criticality is foreseen.
All radioactive wastes disposed in the repository in Japan are LLW, and any measures against theircriticality or residual heat generation are not actually required to be taken into consideration.
Facilities approved under the Radiation Hazards Prevention Law do not necessitate any consideration ofcriticality or removal of residual heat because of the characteristics of the wastes they deal with.
H.1.2

Minimization of the Generation of Radioactive Waste

As mentioned in Section B.3, the Long-Term Program for Research, Development and Utilization of
Nuclear Energy states that minimization and effective use of radioactive wastes are necessary, and it isrequired to promote researches and developments for this purpose.

H-4

Regarding construction of nuclear facilities under the Reactor Regulation Law, “the Regulatory Guide
for Reviewing Safety Design of Light Water Nuclear Power Reactor Facilities” and the “Basic Guide for
Safety Review of Nuclear Fuel Cycle Facilities”, require operators to keep public radiation exposure innormal operation as low as reasonably achievable(ALARA). Operators of nuclear facilities make efforts
to reduce radio-nuclides concentrations in gaseous and liquid wastes to be discharged by means offiltration, absorption, and by decay in storage tanks for gaseous waste and filtration, ion exchange, or
distillation for liquid waste. Solid waste is packed in metal drums, which are stored in dedicated storagepits. Before storing, solid waste is firstly sorted into several categories according to their characteristics,
substances likely harmful to the integrity of waste packages are removed, and the volume is reduced byincineration and compaction. The operators are making efforts to reduce the amount of wastes.
Major nuclear facilities report their annual discharge of gaseous and liquid waste and annual generation,
volume reduction, and the inventory as of the end of the fiscal year of solid waste to the regulatory body,which reports them to the NSC. These statistics are disclosed to the public.
Operators of radioisotope waste management facilities under the Radiation Hazards Prevention Law
report to the regulatory body the amount of annual receipt and accumulated inventories of liquid andsolid wastes in the fiscal year.
Furthermore, the development of technologies are carried out by the operator (licensee) to minimize thegeneration of radioactive waste, such as decontamination technology, melting treatment technology, andrecycling technology of concrete scraps.
As mentioned in Section B, the NSC and Radioactive Waste Safety Subcommittee have shown the basic
concept of the clearance level and its monitoring methods for compliance with clearance level for suchas concrete and metal scraps, which account for a greater portion of waste from dismantling of nuclear
facility. Under the circumstances the Reactor Regulation Law has been amended in May, 2005 and theclearance system has started its application. Waste below the clearance level needs not be dealt with asradioactive material and can be handled in the same manner as non-radioactive waste. The
encouragement of recycling of the waste below the clearance level as far as technically andeconomically feasible is also emphasized in the basic concept.
H.1.3

Interdependencies among the Different Steps in Waste Management

Regulations concerning radioactive wastes in Japan provide that the licensees under the Reactor
Regulation Law shall treat and store radioactive wastes inside their facilities in principle. Treatingprocess and facilities are designed and used so that the waste packages produced are feasible for storage
then disposal in the next step. This clearly means interdependencies among the different steps areappropriately taken into considerations. For those waste packages that were made during the period
when the specification of land disposal was not defined, land disposal of them have become feasible
after the verification of waste packages using the waste package data recorded and kept .
Based on the experiences above mentioned, the radioactive wastes under the Radiation Hazards
Prevention Law are also assured their interdependencies with disposal method to be decided in the
future.
H.1.4

Regulations for Radiation Protection

Criteria of radiation protection in safety of radioactive waste management described in Section F.4 havebeen developed according to the recommendations of International Commission on RadiologicalProtection (ICRP). One of the criteria specific to radioactive waste disposal facility is a dose criterion to
be applied at the end of institutional control of a disposal facility. The “Fundamental Guidelines ofLicensing Review of Land Disposal Facility of Low-Level Radioactive Waste” provide that “theinstitutional control should be completed within a reasonable time period, after which public exposure should
H-5

be kept at such a low level as does not need any control for radiationprotection.” It describes that the dose lower
than which does not need to be controlled is 10 µSv/y, which is the exempt dose for regulations defined in thereport of the Subcommittee on Basic Matters of Radiation Council “Dose Level for Regulatory Control
Exemption at the Near Surface Disposal of Radioactive Solid Wastes” (1978). This value was defined by the
Radiation Council based on the recommendations of ICRP, Standards of IAEA, etc.
H.1.5

Consideration of the Biological, Chemical and Other Hazards

The Reactor Regulation Law prescribes that nuclear facilities shall have their functions appropriately toprevent hazards due to nuclear fuel materials or materials contaminated with nuclear fuel materials. For
this reason, regulations on radioactive wastes require operators to keep radiation effect on workers andthe general public as low as reasonably achievable(ALARA) and also provide requirement to take risks
caused by other than radiation into consideration. The “Rules for Management of Waste of Nuclear Fuel
Materials or those which are Contaminated therewith” stipulates that explosive materials, corrosive
materials and other hazardous materials shall not be disposed of in the repository. It is also stipulated
that waste package shall not contain the materials harmful to the integrity of waste package and its
details are defined in the “Notice on the Technical Details of Measures etc. for Disposal of Nuclear Fuel
Materials etc.”. The materials that are likely to harm the integrity of waste package are:(1) explosive material or material that explosively reacts with water;(2) volatile material;(3) spontaneous-ignitable substance;(4) corrosive material; and(5) material that generates large volume of gases.
Radioactive wastes containing biologically harmful materials such as pathogen etc. generated at
facilities using radioisotope shall be collected by the radioisotope waste management services operator
after appropriate treatment by the generator himself for safety assurance.
H.1.6

Consideration of Impacts on Future Generations

As mentioned in Section B, the policy is stated that the current generation, who received the benefits ofnuclear energy, should bear the responsibility of safe disposal of waste generated by the research,development and utilization of nuclear energy, and should pay continued efforts to that direction.
Radioactive waste generated from nuclear facilities is assumed to be transported to and disposed of in
the repositories. For approval of a LLW disposal facility, the licensing review has been conducted inaccordance with the Fundamental Guidelines of Licensing Review of Land Disposal Facility of
Low-Level Radioactive Waste. This Guidelines describe that the long-term safety assurance of waste
repository facility shall be ensured to avoid imposing excessive impacts on future generations.
And, for the licensing review of for the geological disposal of HLW of which guidelines etc. will be prepared in
the future, “Policy for Safety Regulations Concerning Disposal of High-level Radioactive Wastes (First
Report)” (November, 2000) by NSC states that basic policy is to confirm by the safety evaluation that the
maximum dose evaluated for the general public shall be always lower than the radiation protection level
defined in advance as the standard, thus the impact to the future generation shall be taken into account. In
regard of the time period to be covered by safety assessment, the NSC’s report “Common Important Issues in
Safety Regulation for Radioactive Waste Disposal” (June, 2004) states that necessary studies from theviewpoint of the safety regulation should be carried out referring preceded foreign examples, as the study has
not yet duly progressed to date in Japan.

H.1.7

Consideration of Burdens on Future Generations

The Long-Term Program for Research, Development and Utilization of Nuclear Energy shows
fundamental concept that the current generation receiving the benefits of nuclear energy has
responsibility for safe disposal of radioactive wastes generated by research, development and utilizationof nuclear energy.
In course of a review of a license application for a major nuclear facility, the regulatory body ensuresthat issuance of the license does not pose any impediment to the development and planned utilization of
nuclear energy, and that the applicant has capacities necessary for an adequate facility operation.
In regard of HLW, as mentioned in Section B.3, the Specified Radioactive Waste Final Disposal Act wasenacted in 2000. In accordance with this Final Disposal Act, the Nuclear Waste Management
Organization of Japan (NUMO) was established as a sole implementing body responsible for HLW
disposal, and the electric utilities deposit funds for disposal to NUMO, who entrusts the Radioactive
Waste Management Funding and Research Center with management of the fund. The above law statesthat safety regulations on the disposal of designated radioactive waste is established as a separate law.
Towards the establishment of the law, study on fundamental concepts such as principles of safetyassurance, index and its standard values for safety assessment, period to be covered by safety assessment,
safety assessment models and the parameters, methodology for establishing safety assessment scenario
etc. is being progressed by the NSC.

Examination of the Results of Past Practices

As a result of review it is found that the past practices caused neither radioactive wastes nor nuclear
facilities that require any intervention for reasons of radiation protection.
In Japan, there are small amount of waste rock and mill tailings generated by past activities (test andresearch) as shown below. (*1)
・ Tunnel prospections and mining and milling tests carried out in Ningyo Toge area, Okayama
prefecture from 1957 to 1978.
・ Tunnel prospections carried out in Togo area, Tottori prefecture from 1958 until 1962.
・ Tunnel prospections, solution mining test, and earth sciences research of geologic environment
carried out in Tono area, Gifu prefecture from 1972 until 2003.
These sites are managed as cessation mine under the Mine Safety Law. The amounts of waste rock andmill tailings are shown in the following table.
The amounts of waste rock and mill tailings

For radiation protection, these sites are managed under the Mine Safety Law so as not to exceed 1
mSv/year at the boundary of peripheral monitoring area.
The operator related to these sites is Japan Nuclear Cycle Development Institute(Kamisaibara-son,Tomata-gun, Okayama prefecture and Toki city, Gifu prefecture) and researches and examinations on
permanent measures of the waste rock and mill tailings are being carried out by the operator.
(*1) As these waste rock and mill tailings are not defined as radioactive wastes in Japan, these materials
are out of scope of the Convention in accordance with Article 2 of the Convention. However the statusof these wastes are reported here in accordance with Paragraph 70 of the Summary Report JC / RM.1 /06 / Final version (····In relation to uranium mining and milling wastes, Contracting Parties with such

Siting of Proposed Facilities (Article 13)

1. Each Contracting Party shall take the appropriate steps to ensure that procedures are
established and implemented for a proposed radioactive waste management facility:(i)

to evaluate all relevant site-related factors likely to affect the safety of such afacility during its operating lifetime as well as that of a disposal facility after
closure;(ii)

to evaluate the likely safety impact of such a facility on individuals, society andthe environment, taking into account possible evolution of the site conditions ofdisposal facilities after closure;(iii)

to make information on the safety of such a facility available to general public;(iv)

to consult Contracting Parties in the vicinity of such a facility, insofar as they
are likely to be affected by that facility, and provide them, upon their request,
with general data relating to the facility to enable them to evaluate the likely
safety impact of the facility upon their territory.
2. In so doing, each Contracting Party shall take the appropriate steps to ensure that such
facilities shall not have unacceptable effects on other Contracting Parties by being sited inaccordance with the general safety requirements of Article 11.
H.3.1

Evaluation of Site-related Factors and Impact of Proposed Facilities

The regulatory body, when issuing license for operation of a major nuclear facility in accordance with
the Reactor Regulation Law and its ordinances and rules, conducts a licensing review to ensure thatsiting and the basic design etc. of facility, equipments and components of the facility are adequate toprevent hazards due to nuclear disaster. The regulatory body uses regulatory guides in the licensing
review.
The Basic Guide for Safety Review of Nuclear Fuel Cycle Facilities, which is a regulatory guidecommonly applied to nuclear fuel fabrication, spent fuel reprocessing, use of nuclear fuel material.
under the Reactor Regulation Law defines that sites shall satisfy the following conditions:・ Basic conditions: No event liable to induce large accident is likely to occur at and near a
proposed site of the nuclear fuel cycle facility and there have also been very few events deemed
liable to propagate disaster.
・ Condition during normal operation: Radiation dose to which the general public may be exposed
during normal operations of a proposed nuclear fuel cycle facility are kept ALARA.
・ Condition on an accident: The maximum postulated accidents at the proposed nuclear fuel cycle
facility should not cause excessive exposure to the general public.
These requirements are fundamentally the same as those described in the “Basic Philosophy to Assess
Safety of the Radioactive Waste Management Facilities”, which is a safety review guideline for treating
and storage of wastes as an independent services and those described in the “Fundamental Guideline ofLicensing Review of Land Disposal of Low-Level Radioactive Waste”, which is a safety review
guidelines for disposal facilities.
The “Fundamental Guideline of Licensing Review of Land Disposal of Low-Level Radioactive Waste“ states on the basic condition “no deriving events to induce a large accident is likely to occur at andnear the site of the waste disposal facility, and very few events to expand disaster when an accident
occurs.” Specifically, it is required to confirm by the safety review that there is no obstacle to ensuring

H-10

the safety of the facility taking following events into consideration:(1) Natural phenomena
1) Natural events such as earthquake, tsunami, landslide, depression, typhoon, high tide, flood,abnormal cold wave, heavy snowfall.
2) Geological conditions and landform such as ground conditions, soil bearing capacity, fault.
3) Meteorological conditions such as wind direction, wind velocity, precipitation.
4) Hydrological and hydraulic conditions of rivers, groundwater, etc.
(2) Social phenomena
1) Fire, explosion at a neighboring factory etc.
2) Condition of use of river water, groundwater etc., conditions of land use etc. in relation to foodproduction such as agriculture, livestock farming, fishery, and condition of population distributionetc.
3) Natural resources such as coal, ore etc.
The regulatory body, when approving operation of a radioisotope waste management facility inaccordance with the Radiation Hazards Prevention Law, conducts safety review to confirm thedescriptions in the application are in compliance with the siting conditions, standards on facility,
technical standards etc, provided in the Radiation Hazards Prevention Law and related regulations andstandards, and approves when the application is confirmed appropriate. It is provided that facilities
should be located at a site where landslide and inundation are unlikely to occur, that main structures
should be fireproof or fire-resistant, and that facility should be equipped with shielding walls forradiation protection.

Information Disclosure

License application documents and related information are open to the public at the Nuclear Energy
Library and the Nuclear Library of JNES unless reasons for non-disclosure exist. The official documents
are open to the public upon request made in accordance with the Law on the Disclosure of Information
held by Administrative Agency, which came into force on April 1, 2001, unless reasons fornon-disclosure apply.
Furthermore, license application documents and related other documents are also available to the public
at the National Diet Library.
Official documents containing information about the safety of radioisotope waste management facilities
licensed under the Radiation Hazards Prevention Law are also available to the public upon request inaccordance with the Law on the Disclosure of Information held by Administrative Agency, unlessreasons for non-disclosure apply.
H.3.4

Relationship with Neighboring Countries

Being an islands country, Japan is located at a considerable distance from its neighboring countries. And
then, as long as the safety of nuclear facilities is properly secured within Japan, nuclear facilities in the
country are highly unlikely to have impacts on the neighboring countries safety. Therefore the Japanese
government does not have a rule to consult the neighboring countries about siting of nuclear facilities.
The Japanese government provides neighboring countries with information on the status of the nuclear

H-11

energy of Japan through bilateral consultation, etc.

The details about the review of the safety assessment of a facilities on an accident are described in
Section H. 5.1.
The operator of major nuclear facility other than fuel material use facilities and waste disposal facilities,
under the Reactor Regulation Law or the Electricity Utilities Industry Law, is required to submit a planof a facility construction to the competent minister for approval, and has to have welding inspections ofvessels and pipes of the facility and pre-service inspections of facility at each stage of construction andat the completion of the construction work. The regulatory body confirms that the construction work has
been carried out as approved construction plan and that the facility satisfies the technical standards.
Pre-service inspections include various investigations and tests ranging from structure, strength andleakage of individual components to the functions and performance of the whole facility.
The operator of nuclear fuel material use facility has to have welding inspections, when necessary, andalso has to have facility inspections by the regulatory body at each construction stage and at thecompletion of the construction work. The regulatory body confirms that the facility satisfies thetechnical standards.
In regard of the disposal facility, the Reactor Regulation Law does not have a provision for welding
inspection. It has a provision on the “Safety Verification” of the facility(Fig. H-1) for those on theapproval of construction plan and the pre-service inspections.
The license application to be submitted to the competent minister for a radioisotope waste management
services under the Radiation Hazards Prevention Law must be accompanied by an explanatory
statement setting forth the method of waste management and the locations, structures and equipments ofwaste repackaging facilities and waste storage facilities and waste management facilities. The
provisions concerning the location, structure and equipment of each facility require the applicant, inorder to restrain possible radiological effects, to ensure that shielding walls, other shields, ventilationequipments, and drainage equipments are consistent with the following technical standards prescribedby laws and ordinances:

Technical Provisions for the Closure of Disposal Facilities

The Rules for Waste Disposal Facility provide technical requirements for the waste disposal facilities
and waste packages under the Reactor Regulation Law to be satisfied to ensure pre-and post-closure
safety of the disposal facility Table H.4-1 shows an outline of the technical requirements for waste
disposal facility.
Furthermore, the Fundamental Guidelines for Licensing Review of Land Disposal of Low-Level
Radioactive Waste, issued by the NSC, describes on the institutional control period after the closure of
the facility that the institutional control should be completed within a reasonable time period, after which
public exposure should be kept at such a low level as does not need any control for radiation protection.
H.4.4

Steps to Support the Reliability of Technologies

Operators incorporate commonly applied technologies in domestic and overseas on the design andconstruction of nuclear facilities.
Since 1976, the NSC has been promoting research on the safety of nuclear facilities, environmental
radioactivity and radioactive waste (the safety research). To respond to the possible expansion anddiversification of nuclear power development and utilization, the NSC has utilized the results of thesafety research in the establishment of safety policy, basic principles, and various standards andguidelines.
Since fiscal year 2001, the relevant organizations have been conducting researches related to the areas ofnear surface disposal, geological disposal, and clearance level, contributing to the establishment ofstandards for the disposal of radioactive waste (see Table B.3-2). Subjects of the researches include, in

H-14

the area of near surface disposal, researches on the migration of radio-nuclides and the safety assessment
for disposal of radioactive wastes from Radioisotopes use facilities and research facilities, and, in thearea of geological disposal, researches on the long-term stability of the geological environment and on
the long-term behavior of the engineered barriers and surrounding bedrock, and, in the area of clearance
level, research on verification methods of clearance level of the wastes generated fromdecommissioning of nuclear facilities.
In addition to the above described researches, intensive researches and developments on geologicaldisposal of HLW have been conducted by the government and related organizations allocating the roles
as described in the Long-Term Program for Research, Development and Utilization of Nuclear Energy(2000). The researches and developments consist of researches needed for safety regulations of final
disposal of HLW and safety assessment, basic researches such as the geo-scientific study on thegeological environment of deep underground and researches and developments for technologicalimprovement of reliability of geological disposal technologies. Especially, two underground researchfacilities programs being conducted by Japan Nuclear Cycle Development Institute, one is with granite
and the other with young argillaceous sediments, are expected to be the programs not only for the above
mentioned researches and developments but also for promotion of better understanding of generalpublic in Japan about geological disposal of HLW.

Assessment of Safety of Facilities (Article 15)
Each Contracting Party shall take the appropriate steps to ensure that:(i)before construction of a radioactive waste management facility, a systematic safetyassessment and an environmental assessment appropriate to the hazard presented
by the facility and covering its operating lifetime shall be carried out;(ii)

in addition, before construction of a disposal facility, a systematic safety assessment
and an environmental assessment for the period following closure shall be carriedout and the results evaluated against the criteria established by the regulatory body;(iii)

before the operation of a radioactive waste management facility, updated anddetailed versions of the safety assessment and of the environmental assessment shallbe prepared when deemed necessary to complement the assessments referred to inparagraph (i).

H.5.1

Systematic Safety Assessment and Environmental Assessment

The competent minister, when issuing a license for a nuclear facility under the Reactor Regulation Law,requires the applicant to submit a license application accompanied with documents explaining
meteorology, geology, hydrology and social environment of the site, and safety design of the facility,
and reviews them.
The regulatory guides, used to review a license application documents, require the applicant to perform
safety assessment on the maximum postulated accidents of each nuclear facility prescribed in the guides,
and to confirm that these accidents do not cause any excessive public exposures of radiation.
The regulatory guides require the applicant of a license for a reactor facility or reprocessing facility,
which contains a large quantity of radioactive material, to perform both safety assessments to confirm
the adequacy of safety design of the facility and safety assessment of candidate site to assess theisolation between the facility and the public from the point of view of radiation safety on postulated
accidents. In the series of safety design assessments, the guides require to confirm that assumed
damages to radioactive waste management equipments does not cause any excessive public exposuresof radiation.
The competent minister, when issuing a license for a radioisotope waste management facility under the
Radiation Hazards Prevention Law, requires the applicant to assess the shielding design and theradio-nuclides concentrations in the air and drainage at the boundary of the site, and confirms that theconcentrations do not exceed the limits specified in the regulations.
H.5.2

Assessment for the Period following Closure of a Disposal Facilities

The concept on the management period of disposal facilities is prescribed in the Fundamental guideline
for Licensing Review of Land Disposal of Low-Level Radioactive Waste established by NSC.
Radio-nuclides in LLW are mainly short-lived radio-nuclides, and they decay their radioactivity withtime. For this reason, the control of the facility should be completed within a reasonable time period, after
which public exposure should be kept at such a low level as does not need any control for radiation protection.
Cobalt-60, Cesium-137 etc. in the wastes as the important radioactive nuclides for radiation protection of waste
disposal facility decay to below 1/1000 to 1/10000 after 300 to 400 years, and the radioactivity in the wastes
disposed of will become very small. For this reason, the period of about 300 years to 400 years is cited as a
“institutional control period” referring to examples of foreign countries. And, in the case of the disposal facility
H-17

without engineered barrier, as the disposed waste is non-solidified concrete etc. with low radioactivity level,
disposal stage and the following about fifty years of preservation stage is cited as the “institutional control
period”.
The details of management of disposal facility are described in Section H.7.2.
H.5.3

Updating of Assessments Before Operation of Facilities

The Reactor Regulation Law provides that, when there are changes of the description of the license
application or major changes of the facility design are needed, the operator shall apply for the alterationof the application for a license for a waste disposal facility or the facility design and construction method
and they shall be approved by the competent minister.
The Radiation Hazards Prevention Law also requires operators to apply for alteration to the license
application, when necessary, and it shall be reviewed again by the authority.

An operator approved under the Reactor Regulation Law shall take necessary measures on safe
operation for maintenance of the facility, operation of the equipment, and transport, storage and disposalof wastes. Before the start of operation, the operator is required to prepare Operational Safety Programand submit it to the regulatory body for approval. The program shall defines methods of operation of the
facility, inspection for maintenance of the facility, radiation monitoring, quality assurance etc.. It shallspecify concrete operational conditions, and the facility shall be operated and maintained in compliancewith them. Table H.6-1 shows the contents of the Operational Safety Program of a waste disposal
facility. The operator shall undergo the inspection on the compliance of the program by the regulatory
body (Nuclear Safety Inspection) four times a year. When a periodical facility inspection once a year
finds that the performance of the facility does not conform to the technical criteria defined by the applied
laws and regulations or that the facility does not conform to the operational conditions, the regulatory
body orders the operator to take necessary measures on safe operation such as cessation of use,
modification or repair of the facility, designation of operational method of the equipment etc.
An operator of major nuclear facility shall assign a manager for physical protection to manage theactivities for physical protection of nuclear fuel materials thoroughly. And, the operator shall assign aqualified staff of Reactor, a qualified staff of Nuclear Fuel Material, a qualified staff of Spent Fuel or a aqualified staff of Radioactive Waste among the qualified staff of Nuclear Fuel Material or qualified staff
of Reactor under the Reactor Regulation Law.
Operator licensed under the Radiation Hazards Prevention Law, before the start of operation, prepares
the Internal Rules for Prevention of Radiation Hazards specifying details of inspections, radiation
monitoring and treatment of radioactive wastes, and notifies it to the regulatory body. The Internal Rules
shall specify operational requirements, and the facility shall be operated and maintained in compliancewith them. Table H.6-2 shows the details of the Internal Rules.
Also, operator assigns, among qualified staff, a Supervisor of Radiation Protection who is in charge ofoverseeing prevention of radiation hazards in operation of facility.
H.6.3

Procedures of Operation and Updating of Assessment of a Disposal Facility

In accordance with the Reactor Regulation Law, the Electric Utilities Industry Law, or the Radiation
Hazards Prevention Law, the operator of a nuclear facility, during the operation of the nuclear facility, isrequired to undergo the following inspections respectively.
(1) Nuclear Facilities under the Reactor Regulation Law
1)Periodical Facility Inspection
The regulatory body conducts Periodical Facility Inspections (excluding disposal facilities) oncea year (every 13 months in the case of commercial power reactor facilities) to inspect theconformity of the performance of the facilities and equipment complies with the technicalcriteria defined by the law and its regulations etc.

2)

Nuclear Safety Inspection
The regulatory body posts Nuclear Safety Inspectors to each nuclear facility to conduct the
Nuclear Safety Inspection four times a year to confirm the compliance with the Operational
H-20

Safety Program and the results is open to the public.
3)

Safety Verification of Radioactive Waste Packages
The regulatory body conducts the Safety Verification of Radioactive Waste Packages each time
when waste packages are emplaced in disposal facilities. Actually, the Japan Nuclear Energy
Safety Organization conducts the verification as designated from the regulatory body. Table
H.6-3 shows the technical criteria used in the Safety Verification of Radioactive Waste Packages
generated from reactor facilities.

For the purpose of updating assessment of a disposal facility, the regulatory body, in accordance with
the Rules for Waste Disposal Facility, conducts the Safety Verification of Disposal Facility once again
at the time when the facility is covered with soil and closed. In the verification, the regulatory bodyconfirms compliance with the technical criteria, one of which prescribes that the cumulative amountof radioactivity of each radioactive nuclide contained in all of radioactive waste packages emplacedin the disposal facility shall not exceed the amount of radioactivity of each radioactive nuclide
described in the license application.
The operator, in accordance with the Rules for Waste Disposal Facility, keeps records of disposal,
including the results of the Safety Verification of Disposal Facility, until the waste disposal isterminated.
(2) Facility of Radioisotope Waste Management Services under the Radiation Hazards Prevention Law
1)Periodical Inspection
The regulatory body conducts Periodical Facility Inspections every three years to inspect if theperformance of the facilities and equipments complies with the technical criteria.

2)On-the-Spot Inspection
The regulatory body sends Radiation Inspectors to the facility to conduct On-the-Spot
Inspections as necessity arises.

H.6.4

Technical Support throughout the Operating Lifetime

Throughout the operating lifetime of a nuclear facility, the regulatory body obtains engineering andtechnical advices from advisory committees, which are composed of experts on operational
management, inspection and radiation control, and these advices are reflected in the operation,
maintenance and safety regulation as necessary. The regulatory body also carry out the necessary study
based on the advises to prepare the safety regulations for future disposal of HLW and the low-level
radioactive wastes with relatively higher radioactivity .
The NSC, as described in Section H.4.4, has been promoting researches on the safety(the safety
research) of radioactive waste disposal, which have been conducted by JAERI, JNC and other institutes.
Meanwhile, the operators are collecting information on the operation experience both domestic andoverseas, and accumulating the up-to-date technological knowledge through their own development
project or maintenance activities.
H.6.5

Characterization and Segregation of Radioactive Waste

The Reactor Regulation Law provides disposal method based on the properties and types of radioactive
waste as follows:

shall be stored in a storage facility with special measures preventing spread of contamination.
Reporting of Incidents and Failures

The Reactor Regulation Law or the Electric Utilities Industry Law requires operators to report to theregulatory body about the situation of and the measures taken for incidents or failures occurred at major
nuclear facilities. The criteria on reporting prescribed in these laws for waste disposal facility are shownin Table H.6-5. The regulatory body is further encouraging operators to feedback the measures toprevent a recurrence to other nuclear facilities as well.
H-22

Operators of the facility of radioisotope waste management services subject to the Radiation Hazards
Prevention Law, in accordance with the law, also report to the regulatory body about the details of major
incidents occurred at the facilities and countermeasures taken. Table H.6-6 shows the reporting criteria
under the Radiation Hazards Prevention Law.
In Japan, incidents and failures have been evaluated according to the International Nuclear Event Scale(INES) since August 1992.
H.6.7

Reflecting Operating Experience

Upon receipt of a report on an incident at a major nuclear facility, as noted in the preceding section, theregulatory body immediately announces it to the public and also announces the causes for the incident
and measures to be taken to prevent similar incidents when they become available. The regulatory bodyfully examines the information about the incidents occurred at nuclear facilities and makes effort to
extract and draws the lessons to be learned from the incident with soliciting advices from committeescomposed of experts on operational management, inspection and radiation control. The regulatory body
applies the lessons learned to the operation and maintenance or safety regulations where appropriate.
The regulatory body entrusts its supporting organization to collect and analyze information about
operating experience both at domestic and overseas nuclear facilities, and to provide information to
relevant organizations. For example, NISA entrusts JNES to establish the system to collect and evaluate
domestic and overseas safety information, and the results are shared with JNES and NISA and periodical
surveyed by jointly established “Safety Information Deliberation Committee” for the appropriate
application of them to regulations and for the follow-up of it.
The regulatory body has international mechanism to share information on incidents and accidents
through international organizations, such as the IAEA and the OECD/NEA, as well as under bilateral
cooperation agreements with the foreign organizations.
Meanwhile, electric utilities are collecting and analyzing information about operating experience both
domestic and overseas by themselves and through CRIEPI. They have established an internet library“the Nuclear Information Archives (NUCIA)” to share the domestic safety information among thegeneral public. The NUCIA deals with the domestic safety information including that of minor eventsfrom commercial power reactor facilities and has been open through Internet (http://www.nucia.jp)
since October, 2003. Also they have international mechanisms to exchange information throughInstitute of Nuclear Power Operation(INPO) and World Association of Nuclear Operators(WANO)
Tokyo Center. Some of electric utilities have information exchange agreements with electric utilities orreactor manufacturers in France, Germany, the United States and other countries. Recognizing theimportance of sharing safety information and nurturing safety culture throughout the nuclear industry,
related organizations jointly established a private institute “NS Net” in December 1999. The NS Net
performs peer reviews and other routine activities. NS Net became a part of Japan Nuclear Technology
Institute (JANTI) since April, 2005 and is continuing its activities.
H.6.8

Preparation of Decommissioning Plan of Nuclear facilities

As described in Section F.6, the operator of a nuclear facility under the Reactor Regulation Law shallprepare a decommissioning plan for the facility and shall obtain an approval by the regulatory body.
An operator of the facility of radioisotope waste management services licensed under the Radiation
Hazards Prevention Law, in order to terminate the services, shall take measures such as transfer ofradioisotopes in its possession, decontamination of materials contaminated by radioisotopes, anddisposal of contaminated materials, and shall report to the regulatory body about the measures taken.
H-23H.6.9Preparation of Plans for the Closure of Disposal Facilities

The operator of a waste disposal facility, when applying for a license, is required to submit a plan forclosure of the disposal facility, plan for post-closure management which includes the expected period forthe institutional control, and an approval by the regulatory body. The operator, when closing a disposal
facility, are requested to take the Safety Verification of Disposal Facility by the regulatory body, as

Implementation of Institutional Controls

The Fundamental Guidelines of Licensing Review of Land Disposal Facility of Low-Level Radioactive
Waste issued by the NSC require that operators of disposal facilities should, in accordance with the
ALARA principle, manage a disposal facility taking account of types and radioactivity levels of waste
disposed of, until the radioactivity of waste disposed of in a near surface disposal facility decays withtime to the level as low as it poses no safety hazards to the public (hereinafter referred to as Step-wiseControl).
The regulatory body requests a license applicant for waste disposal to submit a plan for step-wisemanagement and examines the conformity to the requirements specified in the Fundamental Guidelinesof Licensing Review of Land Disposal Facility of Low-Level Radioactive Waste. The Step-wise Control
required by the above guidelines is as follows.( Figure H-1)
(1) A disposal facility with engineered barrier (*1):
1)

The First Stage:

H-31

In a disposal facility, a peripheral monitoring area where access is controlled, and a disposal
facility preservation area where patrol and inspection are conducted, are established. Leakage ofradioactive materials out of engineered barrier (*2) is monitored, and if leakage occurs remedial
measures are taken. (Monitoring and prevention of leakage from engineered barriers)
2)

The Second Stage:
In a disposal facility a peripheral monitoring area where access is controlled, and a disposal
facility preservation area where patrol and inspection are conducted, are established. Leakage ofradioactive materials out of engineered barrier with groundwater to the biosphere is monitored.
(Monitoring of leakage and migration from engineered barrier, and retardation of migration by
natural barrier (*3) and engineered barrier)

3)

The Third Stage:
A disposal facility preservation area where patrol and inspection are conducted is established.
Farming and other specific human activities in this area are restricted or prohibited.
(Retardation of migration by natural barrier, and prohibition or restriction of specific humanactivities)*1: The case that wastes solidified in a container etc. are disposed of in a near surface disposal facility
with engineered barrier.
*2: “Engineered barrier” is an artificial structure such as the concrete pit, filling materials such as soil
and sand for open space between and around waste packages emplaced, and monolithicallyconsolidated waste packages for prevention and reduction of leakage from the wastes disposed ofinto the biosphere.
*3: “Natural barrier” is the soil etc. surrounding engineered barrier or waste packages and is expected toretard migration of radioactive materials leaked from the wastes disposed of into the biosphere.
(2) A disposal facility without engineered barrier (*4)
1)

The Disposal Stage:
A peripheral monitoring area where access is controlled, and a disposal facility preservation area
where patrol and inspection are conducted, are established. Leakage of radioactive materials outof disposal facility with groundwater to the living environment is monitored. (Retardation andmonitoring of migration into the biosphere)

2)

The Preservation Stage:
A disposal facility preservation area where patrol and inspection are conducted is established.
Farming and other specific activities in this area are restricted or prohibited (Retardation of
migration into the biosphere, and prohibition or restriction of specific activities)*4: The case that wastes such as concrete not solidified in a container etc. are disposed of in a nearsurface disposal facility without engineered barrier.
The control period is supposed to last 300 to 400 years for a disposal facility with engineered barrierreferring to foreign cases. And, in the case of disposal without engineered barrier, as the disposed waste is
non-solidified concrete etc. with low radioactivity level, disposal stage and the following preservation stage ofabout fifty years are regarded as the “institutional control period”.

H-32

H.7.3

Intervention Measures if Necessary

When issuing a license, the regulatory body requests the operator to take following measures during
each stage of institutional control.
In the First Stage, if a leakage of radioactive material from engineered barriers is detected, the operator
should immediately repair the barriers to prevent leakage. In the Second Stage, the operator should
monitor leakages from engineered barriers and, if necessary, take measures to retard migration ofradioactive material. At the same time, the operator should conduct patrol and inspection of the disposal
facility and, if necessary, restore the cover soil and others. In the Third Stage, the operator should
conduct patrol and inspection to prevent any action specified in regulations, and, if necessary, restore thesoil cover and others.

Section I. Transboundary Movement (Article 27)
1. Each Contracting Party involved in transboundary movement shall take theappropriate steps to ensure that such movement is undertaken in a manner consistent
with the provisions of this Convention and relevant binding international instruments.
In so doing:(i)a Contracting Party which is a State of origin shall take the appropriate steps toensure that transboundary movement is authorized and takes place only withthe prior notification and consent of the State of destination;(ii) transboundary movement through States of transit shall be subject to thoseinternational obligations which are relevant to the particular modes of transportutilized;(iii) a Contracting Party which is a State of destination shall consent to atransboundary movement only if it has the administrative and technicalcapacity, as well as the regulatory structure, needed to manage the spent fuel or
the radioactive waste in a manner consistent with this Convention;(iv) a Contracting Party which is a State of origin shall authorize a transboundary
movement only if it can satisfy itself in accordance with the consent of the Stateof destination that the requirements of subparagraph (iii) are met prior totransboundary movement;(v)a Contracting Party which is a State of origin shall take the appropriate steps topermit re-entry into its territory, if a transboundary movement is not or cannot
be completed in conformity with this Article, unless an alternative safearrangement can be made.
2. A Contracting Party shall not licence the shipment of its spent fuel or radioactive waste
to a destination south of latitude 60 degrees South for storage or disposal.
3. Nothing in this Convention prejudices or affects:(i)the exercise, by ships and aircraft of all States, of maritime, river and air
navigation rights and freedoms, as provided for in international law;(ii)

rights of a Contracting Party to which radioactive waste is exported forprocessing to return, or provide for the return of, the radioactive waste andother products after treatment to the State of origin;(iii)

the right of a Contracting Party to export its spent fuel for reprocessing;(iv)

rights of a Contracting Party to which spent fuel is exported for reprocessing toreturn, or provide for the return of, radioactive waste and other products
resulting from reprocessing operations to the State of origin.

The electric utilities in Japan have concluded reprocessing contracts with British and French firms andhave exported 7100 tons of spent fuel between 1969 and 2001.They, in return, receive new nuclear fuelmaterial recovered from the spent fuel and vitrified packages (HLW) generated in the reprocessing.
Eight hundred and ninety-two vitrified packages were sent back to Japan between 1995 and March 2005
and the remaining packages will be returned in the next ten-odd years. As they started constructing a
reprocessing plant at Rokkasho-Mura in Aomori Prefecture in 1993, there would be no plan to export
more spent fuel after 2002, with an exception of the US produced fuel for research reactor (which should
be returned under the bilateral agreement between Japan and the US.)

Transboundary Movement

I. 1. 1

Steps to Ensure Prior Notification and Consent of the State of Destination

For the export of the spent fuel or the radioactive waste, the Foreign Exchange and Foreign Trade
Control Law provides that an applicant should apply for and obtain the Export Permit from the Ministerof METI. This Export Permit should be applied once it is confirmed that the authorities of the State ofdestination recognized the administrative and technical capacity of the importer.
I. 1. 2

Steps to Ensure Transboundary Movement Subject to International Obligations

Japanese domestic laws, such as the Ship Safety Law, etc, have incorporated obligations under the IAEA
Regulations for the Safe Transport of Radioactive Materials and relevant international conventions oneach mode of transport, such as International Convention for the Safety of Life at Sea (SOLAS), etc.
I. 1. 3

Consent as a State of Destination

After being notified by a State of origin of a transboundary movement to Japan of the spent fuel or theradioactive waste, the government of Japan decides whether it gives consent to the transport, andnotifies its decision to the State of origin.
Japan expressed that, upon notification from a State of origin, it would consent to the import of returned
radioactive waste as long as such transport would comply with the safety regulation of Japan.
I. 1. 4

Confirmation of the Capacity of a State of Destination

The Foreign Exchange and Foreign Trade Control Law provides that an exporter should apply for andobtain the Export Permit from the Minister of METI for the export of the spent fuel or the radioactive
waste. The Minister of METI issues the Export Permit after confirming the general conditions of safetyof the country of destination such as its regulatory structure, the membership in relevant international
agreements, and the administrative and technical capacity of the importing body. In other words, theexport shall be permitted only if it is confirmed that importing body has administrative and technicalcapacity of management of spent fuel and radioactive waste.
I. 1. 5

Steps to Permit Re-entry in case of Uncompleted Transboundary Movement

The Import Trade Control Order allows, as special exemption, re-entry of exported goods, in case of
uncompleted transboundary movement so long as original characteristics and configuration of exported
goods are preserved, and the other case of the exemption is a transport accident. Re-entry of exported
spent fuel and radioactive waste is allowed by that provision.
I. 2

Steps to Ban Shipment to a Destination South of Latitude 60˚ SouthThe Foreign Exchange and Foreign Trade Control Law provides that an applicant should apply for andobtain the Export Permit from the Minister of METI for the export of the spent fuel or the radioactive
waste. The Export Permit shall not be granted for the export of spent fuel or radioactive waste to a
destination south of latitude 60 degrees south for storage or disposal.

Section J.

Disused Sealed Sources (Article 28)

1. Each Contracting Party shall, in the framework of its national law, take the appropriate
steps to ensure that the possession, remanufacturing or disposal sealed sources takes
place in a safe manner.
2. A Contracting Party shall allow for reentry into its territory of disused sealed sources if,
in the framework of its national law, it has accepted that they be returned to a
manufacturer qualified to receive and possess the disused sealed sources.
J.1

The infrastructure for regulatory control

In order to regulate radioactive sources, the Law Concerning Prevention of Radiation Hazards
due to Radioisotope etc. (June 10, 1957 Law of No. 167), (In short, Radiation Hazards
Prevention Law) has been enacted, which provides, in essence, that those intending to use
radioisotopes etc. must obtain the license from the Minister of Education, Culture, Sports,
Science and Technology (In short, MEXT). There are about 5000 licensees and each licensee is
responsible for the safety of the sources. All the sources are under proper management andcontrol.
The competent regulatory authority is MEXT. MEXT has been carrying out safety review andon-the-spot inspection.
The objective of Radiation Hazards Prevention Law is to prevent radiation hazards to radiation
workers and the public when radiation or radioisotopes are used. It is recognized that Radiation
Hazards Prevention Law has been functioning effectively as stated below.
(1) The person who uses more quantities of radioactive sources than specified shall apply to
MEXT for license, or notify MEXT.
(2)Radiation Hazards Prevention Law provides technical criteria and requirements, such as
criteria relating to the use of facilities, dose limits for radiation workers, etc. For example,
the licensee is required, from the point of radiation safety, to; 1) be equipped with lock in
all facilities for uses, storage and disposal of radioisotopes; 2) install walls or fences for
restrict to entry at the boundary of controlled area and the facility of liquid waste disposal;
3) restrict access to controlled area without permission of supervisor of the facility. These
safety measures will effectively work also for security, such as physical protection.
(3)Licensee is responsible for annually reporting to MEXT regarding facility management.
MEXT carries out inspections of the facility if needed, and check that the management isin conformity with the license.

As a result of this strict regulation system as described above, there has been no incident, suchas excess exposure to the public by “orphan sources”.
J.2

Management of radioactive sources at the end of their life cycles

The licensee is regulated by law to hand over radioactive sources only to license holders who
are authorized to receive and use the sources, and the disused radioactive sources are by practicehanded over from the licensees to specific licensees. Licensees have obligation to report theresults of such handover to MEXT when they stop using the sources.
The licensee has a responsibility to do an annual inventory check of both sealed and unsealed
radioactive sources and to report the results to MEXT.
Many sources are imported from foreign countries and the sources with long half-life and highactivity are sent back to the original foreign manufactures.
Regarding the distribution of radioisotopes and sealed sources in Japan, one supplier (Japan
Radioisotope Association) carries out consistently from distribution and delivery of almost allradioactive sources to recovery of disused radioactive sources.
Radiation Hazards Prevention Law provides for penalty and clarifies licensee have theresponsibility for safe control of the radioactive sources.
As the result of this, there have been no incidents of serious radiation hazard involving
radioactive sources or serious radiation hazard involving orphan sources until now.
J.2.1

Criteria for the Storage of Disused Sealed Radioactive Sources

In Japan, Radiation Hazards Prevention Law lays down technical criteria relating to storage
sealed sources as stated below.
(1) Sealed sources shall be put in containers and stored in storage pits or bins.
(2) Seals sources shall not be stored in quantities exceeding storage capacity.
(3) Appropriate measures, such as 1) installing a shield, 2) distancing personnel from sealed
sources, and 3) shortening the time during which personnel may be exposed to radiation,
shall be taken in order to prevent personnel engaged in handling of radioactive substancesfrom being exposed to radiation exceeding the effective dose limit.
(4) Appropriate measures, such as immobilizing storage bins, shall be taken in order to prevent
containers storing sealed sources from being carried from one place to another without
permission.
(5) Appropriate measures, shall be taken in order to keep the activity concentration in the air ofJ-2

radioisotopes in storage facilities from exceeding the concentration limit.
(6) Personnel shall be prohibited from eating, drinking or smoking in a place where an oral andinhalation intake may occur.
(7) Appropriate measures shall be taken to prevent surface contamination from exceeding thesurface contamination limit.
(8) Radioactive contaminated substance whose surface concentration exceeds one-tenth of thesurface concentration limit shall not be taken out from the controlled area without
permission.
(9) Appropriate measures shall be taken in order to prevent unauthorized persons from entering
the controlled area.
J.2.2

Reentry of Returning Sealed Sources

As long as a manufacturer has license and meets the regulations specified in the Radiation
Hazards Prevention Law, reentry of approved type of sealed sources returning from abroad areallowed within the license of storage capacity. In this case, the manufacturer intending topossess or renew returned sealed sources is required to store them in accordance with the above
mentioned storage criteria.
J.2.3

Response to Missing Radioactive Sources

In case of loss of any radioactive source, the licensee shall immediately report the matter to thepolice and MEXT. While MEXT orders the licensee immediately to search the sources, thepolice carry out criminal investigations, if the loss relates to criminal acts.
MEXT is now in preparation of notification system for evaluated rating of radioactive source
events based on the additional guidance of the International Nuclear Event Scale (INES) thatwill be submitted in near future.
J.2.4

Response to Orphan Sources

When the lost sources are found, the police and the fire service immediately take an initialaction including setting of exclusion area, radiation survey and immediate assessment of thesituation. MEXT requests the discoverer(s) of the sources that safety measures should be taken
and also dispatch a radiation inspector to confirm that the safety measure has been properly
taken. These orphan sources that have been found are to be recovered by the experts.

J-3J.2.5Detection for Orphan Sources

About 30 percent of the operators of scrap metal recycle industry voluntarily carry out radiation
monitoring with gate type monitors or portable monitors. At the gateway of almost all the blast
furnace or electric furnace steel companies, which use such scrap metal, carry out radiation
monitoring on acceptance of the scrap metal for use.
The steel industry and the scrap metal recycle industry are voluntarily taking measures such as
development of manuals and training courses to cope with the discovery of orphan sources.
The Customs conducts inspections to detect such sources by having set up radiation
measurement equipment and X-ray machines in main ports
J.2.6

Response to Accident Relating Radioactive Sources

In case of accidents involving radioactive sources, the police and the fire service perform initial
response immediately on notification. MEXT dispatches radiation inspectors to advise thelicensee to take suitable measures.
J.2.7

Progress in Establishing a National Register of Radioactive Sources

Users of radioactive source must obtain licenses of MEXT, or submit notification to MEXT by
Radiation Hazards Prevention Law, and MEXT as the regulatory body oversees and verify theradioactive sources used by the licensees as follows.
Before Use:
These who intend to use radioactive sources must apply for license to MEXT. In thisapplication, the applicant has to indicate the nuclide, its radioactivity and the number
for each radioactive source.
After the beginning of use:
The licensee must perform an annual inventory check of radioactive sources, the resultof which should be included in the annual report of facility management. This report
includes not only all the sealed sources including Category 1 and 2 sources but also all
the unsealed sources, and MEXT verifies the consistency with the relevant license
application. In case of disused sources, MEXT asks the licensee for the report that thelicensee has handed over the sources to another licensee.
MEXT requests no information by the above report regarding the source ID number and theJ-4manufacturer, etc. The regulatory authority, however, will know such information of source ID
number and the manufacturer, etc. as a result of the fact that, in Japan only one supplier imports
and delivers category 1 and 2 sources to the domestic users.
From now on, the regulatory authority is considering establishing the system of national registryof sealed sources including source ID number and the manufacturer, etc. at least for category 1
and 2 sources, taking into consideration consistency with source registration systems in othercountries.

Section K.

Planned Activities to Improve Safety(1) Preparation of Laws and Ordinances
There are safety examination guidelines and legislations, etc. to be prepared for safety regulations ofradioactive waste management from now on, such as disposal of high level radioactive wastes,disposal of low-level radioactive wastes with a comparatively high radioactivity level, disposal of
uranium wastes, disposal of wastes containing transuranic nuclides, and the value of materials not
requiring treatment as radioactive wastes. These are shown in Table B.3-2 as the status of activities
concerning preparation of regulation on radioactive waste disposal.
Moreover, the "Law for Saving and Management of the Reserve Funds for Reprocessing etc. of Spent
Fuels from Nuclear Power Generation" was enacted in May 2005, but related legislations etc. areunder preparation at this moment.
The NSC and the related regulatory bodies continue to study and prepare these safety examination
guidelines and legislations etc.
(2) Steps to Support Reliability of Technology
For management of radioactive wastes, especially for disposal, it is important to improve its safety andreliability of disposal technologies.
Therefore, regulatory bodies continuously obtain specialist's engineering and technical advices andreflect them in operation and maintenance and safety regulations, as needed, for operation
management, inspection and radiation management during the operation time period. Safety
researches are conducted based on regulation needs of the Nuclear and Industrial Safety Agency;
On the other hand, operators continuously promote to buildup the newest technical information bycollection of the internal and external information on operational experiences, technologicaldevelopments by self-finance, maintenance and repair activities, etc.
For researches and developments for reliability improvement, the implementing body continues totakes charge of technical development on geological disposal of high-level radioactive wastes, aiming
at safe operation and improvement for profitable and efficient final disposal, and the national
government and agencies concerned implement researches and developments necessary forestablishing safety regulations and safety evaluation for final disposal, fundamental researches anddevelopments such as scientific investigation of deep layer, etc., and technical developments etc. forreliability improvement of geological disposal technologies. Especially, the Japan Atomic Energy
Agency (JAEA) promotes researches and developments for confirmation of the reliability ofgeological disposal technologies and establishment of safety evaluation methods at the two deep layer
research facilities proceeding for the granite and sedimentary rock, the Quantitative Assessment
Radionuclide Migration Experimental Facility, etc. And also, these deep layer research facilities areplanned and expected to facilitate not only as the place of research and development of geologicaldisposal, but also as a place to deepen understanding of the research and development for thegeological disposal in Japan.
Since fiscal year 1976, the NSC has been promoting research projects concerning the safety ofenvironmental radioactivity and radioactive waste at nuclear installations. The products of thesesafety research projects have been reflected in the formulation of various standards and guidelines,
including principles such as safety policy and basic ideas, standards on specific means of achieving
safety, and specific guidance.
The Committee, in developing the research programs on the safety, decided the “Important Research
Programs on the Nuclear Safety” in July 2004 to develop the “Basic Guidelines for Safety
K-1

Examination”, which defines indicators for the safety evaluation and their reference values, etc.,
before selection starts for the detailed investigation area, which is shown in the “classification ofbasic concepts for disposal and status of activities preparing for relevant regulations” (Table B.4-2)
for disposal of radioactive wastes and the “Fundamental Concept on the Safety Regulations for
Disposal of High-Level Radioactive Wastes (the first report)”, and to develop the “Safety
Examination Guidelines” before the safety examination starts incorporating the new knowledge
according to circumstances. The report "Important Research Programs" indicates, as safety
researches on radioactive wastes and decommissioning field to be conducted intensively in five years
starting 2005, two researches to promote the study about environmental requirements or basic
guidelines for selection of the detailed investigation area, etc. of the construction site for the disposal
facility of high-level radioactive wastes and the study for developing the fundamental concept forsafe operation of processing and disposal of high beta and gamma wastes, TRU wastes, uranium
waste etc.
Moreover, in July 2003, the Radioactive Wastes Safety Subcommittee, Nuclear and Industrial Safety
Subcommittee, Advisory Committee for Natural Resources and Energy showed the importantresearch tasks which should be investigated from now on in the “Toward Ensuring Foundation for the
Safety Regulation of High-Level Radioactive Waste Disposal”, and those tasks will be promoted by
the supporting organization for safety regulations, the Japan Nuclear Energy Safety Organization, as acenter, utilizing the results of researches of all organizations including the above-mentioned deep
layer research facilities, and the outcomes will be reflected in the preparation of the future safety
regulation system.

I. LONG-TERM PROGRAM FOR RESEARCH, DEVELOPMENT AND
UTILIZATION OF NUCLEAR ENERGY (EXCERPT)(Atomic Energy Commission, November 24, 2000)
Part I: The Current Status of Research, Development and Utilization of Nuclear Energy, and Future Plans
2. Nuclear Fuel Cycle
2-2. Significance of the Nuclear Fuel Cycle for Japan
From the state of the world, and the situation in Japan in particular, it is apparent that diverse efforts
must be made over the long term to secure a steady supply of energy through technological means.
Nuclear power generation contributes to economic efficiency, supply stability and the environmental
acceptability of Japan's energy supply systems. Nuclear fuel cycle technologies have the potential to
improve further on these attributes, and to permit the benefits of nuclear power generation to be enjoyed fora longer period of time. Technology for reprocessing spent fuel, rather than directly disposing of it, andrecovering plutonium and uranium for use as fuel, require facilities enabling nuclear material control aswell as safety control, in light of the nature of such technology, which is to chemically treat material withhigh radioactivity and separate plutonium and other elements, necessitating, therefore, a great deal of
facility investment. On the other hand, such technology economizes on uranium resources and improves
supply stability. It is, therefore, appropriate to basically reprocess spend fuel and make effective use ofplutonium, uranium and other elements, while securing safety and nuclear non-proliferation. Taking
economic efficiency into account, Japan should make the reprocessing of spent fuel and the use ofrecovered plutonium and uranium its basic policy, considering the geographical and resource conditions of
the country.
(omission)
In the use of plutonium through the reprocessing of spent fuel, there are concerns about safety andnuclear proliferation, and doubts about economy and the economic efficiency of research and development
investment. In order, therefore, to promote the use of plutonium, it is important to ensure safety, and to
dedicate effort to explaining the concept to the people, focusing on securing a stable supply of energy. It isequally important, at the same time, to actively carry out promotional activities to enhance understandingon the part of the international community of Japan's policy on the use of plutonium, and to reiterate to theworld Japan's philosophy of firmly adhering to the peaceful uses of nuclear power and its systems.
(omission)
Part II : Future Prospects for Research, Development and Utilization of Nuclear Energy
Chapter 3: Nuclear Power Generation and the Nuclear Fuel Cycle
1. Basic Policy
The present generation, which enjoys the benefits of nuclear power, has the obligation to do its utmost
for the safe disposal of radioactive waste resulting from the research, development and utilization of thisenergy source. Accordingly, continued efforts will be exerted to achieve steady progress in the proper
disposal of such waste.
3. Nuclear Fuel Cycle Projects
3-4. Reprocessing of Spent Fuel from Light Water Reactors
Spent fuel from light water reactors in Japan, with the exception of a portion contracted out to the Tokai
Reprocessing Facility of the Japan Nuclear Cycle Development Institute, has been reprocessed by overseas
contractors. Meanwhile, taking into account various relevant factors, specifically the demand for domestic
reprocessing, private Japanese nuclear operators conceived the Rokkasho-mura Spent Fuel Reprocessing
Plant based on the operational experience accumulated at the Tokai Reprocessing Facility, and on
technologies and experience in countries advanced in the reprocessing field. The parties are now pushing
forward with construction of the plant in order to have it in commercial operation by 2005.
Mainly from the viewpoint of securing fuel cycle independence, Japan intends in principle to reprocess
all spent fuel domestically from now on, and the private nuclear operators are expected to make steadyprogress with the construction and operation of the Rokkasho-mura facility, the first commercial-scale
reprocessing plant in Japan, so that commercial reprocessing technology will be firmly establisheddomestically. As long as the reprocessing plant and intermediate storage projects progress smoothly and onschedule, it is unlikely that an overseas reprocessing option will be needed. In dealing with this topic, it isalso important for Japan to consider reactions in the countries facing the sea lanes used for the
Annex1-1

transportation of nuclear materials.
(omission)
3-5. Intermediate Spent Fuel Storage
Intermediate storage of spent fuel provides an adjustable time period until the fuel is reprocessed andthus lends an element of flexibility to the nuclear fuel cycle as a whole. In Japan, a law concerningintermediate storage was enacted in 1999, and the private sector is now making preparations forcommercial operation of storage facilities by 2010. It is expected that an implementing entity capable ofproperly operating and managing these facilities will carry out the project in the years ahead under the basic
principle of securing safety.
(omission).
4. Treatment/Conditioning and Disposal of Radioactive Wastes
Radioactive waste is generated primarily at nuclear power plants and nuclear fuel cycle facilities(including waste returned from abroad after spent fuel reprocessing under contract), but some does comefrom universities, research institutes, medical institutions and other facilities. Such waste should be safely
treated/ conditioned and disposed of by the generators. The government should provide guidance to or
regulate the generators to ensure that the treatment/conditioning and disposal are carried out properly andsafely.
4-1. Commitment to Waste Disposal
Some low-level radioactive waste from nuclear power plants has already been buried
underground. Based on studies of methods of disposal, a basic policy has been presented on the disposal ofother radioactive waste, excluding uranium waste, the disposal of which is now under investigation anddiscussion.
As to radioactive waste for which no specific disposal plan has yet been proposed, it is essential that thegenerators and other interested parties formulate and implement a specific plan through sufficientconsultation and cooperation so that they can promptly start safe, efficient treatment/conditioning anddisposal. During the implementation of the plan, the government should support the interested parties'
efforts, whenever necessary, to prevent waste disposal problems from adversely affecting the development
and utilization of nuclear energy.
Since radioactive waste varies greatly in its level of radioactivity and in the type of radioactive material
contained, arrangements should be made to classify the waste by method of disposal, regardless of the
facility from which it comes, and take specific measures for its treatment/conditioning and disposal.
(1) Waste for Geological Disposal
Radioactive waste having relatively high radioactivity and containing large amounts of radioactive
materials with a long halflives should be disposed of by a method capable of securing safety for a long
period of time, so that the living environment will not be affected. This requires the use of geologicaldisposal, which, after providing engineering barriers to prevent radioactive materials from leaking out,buries the waste in stable underground zones several hundred meters deep, which serves as a naturalbarrier.
(High-Level Radioactive Waste)
Japan's policy is that high-level radioactive waste remaining after the recovery of plutonium, uraniumand other useful materials from spent fuel by reprocessing should be solidified in a stable form and, after
being stored for 30 to 50 years for cooling, buried under the ground by the geological disposal
method. Vitrified high-level radioactive waste is already stored at a repository in Rokkasho-mura, Aomori
Prefecture. According to the "Final Disposal of Designated Radioactive Waste Program," which was
issued on October 2, 2000, under the Law on Final Disposal of Designated Radioactive Waste, "final
disposal will start sometime in the latter half of the 2030's."
In selecting disposal sites, an important factor is gaining understanding and support from residents
concerned. In order to do so, it is important to ensure transparency through thorough information
disclosure. The government, electric utilities and the implementing entity, a leading player in site selection,
should perform each duty with proper role sharing and mutual cooperation. For this purpose, thegovernment should clarify the political significance of final disposal and its efforts to secure safety, andendeavor to obtain understanding from residents. It should also provide all necessary systems and setups
for coexistence between the planned disposal facility and the local community; while the utilities and others
having basic responsibility as the waste generators should carry out activities to gain public understandingof the disposal project, with cooperation from the implementing entity and the government, and should
work actively with the implementing entity in selecting disposal sites.
(omission)

Annex1-2

(Radioactive Waste Other than High-Level Waste)
In addition to high-level radioactive waste, some other radioactive waste also requires geologicaldisposal. As that waste varies widely in its chemical and physical properties, it is important for waste
generators and other interested parties to closely cooperate with one another in carrying out research anddevelopment of waste treatment and disposal technologies to pave the way for reasonable disposal of thiswaste, taking into consideration the diversity of its properties and making use of the results of research anddevelopment efforts for the disposal of high-level radioactive waste.
(Partitioning and Transmutation Technology)
The technology to separate radioactive materials with long halflives contained in high-level radioactive
waste and convert them into short-lived or non-radioactive, stable materials using a reactor or an
accelerator is still at an early stage of research and development, but it should be able to contribute to
reducing the burden of waste treatment and disposal, and to effective utilization of available
resources. Research and development activities for partitioning and transmutation technology should be
carried out based on periodic assessments, in coordination with the development of nuclear fuel cycle
technology as a whole. It should be borne in mind that commercialization of partitioning and transmutation
technology will not eliminate the need for geological disposal of radioactive waste.
(2) Waste for Disposal with Institutional Control
Radioactive waste whose radioactivity attenuates to a sufficiently low level as to no longer affect theliving environment within a period for which institutional management is realistic can be safely disposed ofin the ground at a relatively shallow depth, usually by combining engineering and natural barriers, and,after disposal, managing it properly according to its radioactivity. Even waste containing radioactive
materials with long halflives can be safely disposed of by the same method and with the same post-disposal
management if the concentration of such materials is low enough.
From now on, therefore, specific measures should be taken to pave the way for disposal of low-level
radioactive waste, other than that which the nuclear power plants have already begun disposing of it inconcrete vaults. In implementing these measures, a study should be conducted not only on the disposing ofwaste at different sites based on its place of origin, but on disposing of waste by two or more disposal
methods at the same site, and on disposing of waste subject to the same disposal method at the same site,
regardless of its place of origin.
4-2. Decommissioning of Nuclear Facilities
Such nuclear installations as commercial power reactors, test and research reactors, and nuclear fuelcycle facilities, should be decommissioned when the time comes at the responsibility of their operators,
under the basic principle of securing safety while gaining the local community's understanding andsupport. It is expected that the land, after the decommissioning of commercial power reactors, will serve assites for new nuclear power plants, again with the understanding of their communities.
4-3. Reduction of Waste Generation and Promotion of its Effective Use
Steps should be taken to reduce the amount of waste generated and to recycle/reuse it. Research anddevelopment to those ends should be actively pushed forward. Interested parties and the competentauthorities should jointly conduct an extensive study on the uses of such waste and the development ofsystems for that purpose, including satisfactory safety checks. Waste with a radioactivity concentration
below the "clearance level" need not be dealt with as radioactive material, and may be handled in the same
way as conventional waste in respect of safety. In principle, it is important to recycle waste to the fullest
extent practical and reasonable.

(3) Radioactive Waste Processing and Disposal Policy(AEC, Special Committee on Processing and Disposal of Radioactive Waste, October 8, 1985)
Chapter 1. Implementation Organization and Allocation of Responsibilities for Processing andDisposal of Radioactive Wastes
2. Fundamental Concept(1) Responsibilities of waste generators and the government
Since the radioactive wastes are generated with the business activities of the nuclear business operator, it isconsidered that the responsibility to process and dispose of the wastes appropriately and surely shall beborn by the nuclear business operator as a generator of wastes (referred to hereinafter, as "generator").
On the other hand, the government bears the responsibility to performs the research and development, andsafety regulation of processing and disposal of radioactive wastes, and also is required to play appropriate
roles in the implementation of the disposal from the viewpoint that the long term assurance of safety fordisposal of radioactive wastes and the promotion of nuclear energy development and utilization smoothly
as planned. Especially, the government is required to take responsibility to perform appropriately andsurely for disposal of high level radioactive wastes.
(2) Relationship between generators and radioactive disposal business operators
When the generator carries out the processing and disposal of the radioactive waste by himself, thegenerator concerned shall take the legal responsibility for ensuring safety of the processing and disposal.
On the other hand, it may be a possible for the independent business operator having sufficient economical
and technical capability (referred to hereinafter, as "radioactive disposal business operator") are entrusted tomonopolize the processing and disposal of radioactive waste for efficiency and rationality reasons, and insuch case, it is more appropriate for the radioactive disposal business operator to take the legal
responsibility for ensuring safety of the processing and disposal, from viewpoints of concentrating the
responsibility for ensuring safety and performing the efficient processing and disposal. In that case, it isimportant for the generators to bear expense required for the processing and disposal, and also to give
suitable support to the radioactive disposal business operator so that the processing and disposal may be
carried out smoothly.

(4) Basic Concept for Safety Regulations for Land Disposal of Low Level Solid
Radioactive Wastes(The Committee on Safety Regulations of the Radioactive Waste, the NSC, October 11, 1985)
Chapter 2. Concept of Ensuring Safety of Land Disposal
Section 1. Fundamental Concept of Disposal of Radioactive Wastes(1) Radioactive wastes are classified generally by the place of generation and variety, as well as theconcentration of radioactive materials, into the low level radioactive waste generated at nuclear power
plants, etc., the high level radioactive wastes generated at reprocessing plants, or the TRU (Trans Uranium)
waste generated at reprocessing plants or the plutonium uranium mixed oxide (MOX) fuel fabrication
plants, etc., and the following measures for disposal of those wastes are basically taken according to therespective characteristics.
(2) In principle, the radioactive wastes shall be disposed with the policy of preventing the any hazardous
impact of radioactivity to the human environment, therefore, it is essential to isolate it safely from thehuman environment until the radioactivity decays low enough level at which it does not cause any safety
problem, by processing it in the form suitable for the disposal type chosen.
(3) The methods and time periods for isolation from the human environment differ depending on
characteristics of radioactive wastes, especially the kinds and concentrations of radionuclides in the wastes,
the methods and the time periods shall be chosen presuming that safety of disposal at the final stage shallnot rely on the integrity of engineered barriers or the human management activities.
(4) As the current disposal methods of radioactive wastes, there are mainly four types; the method by whichto prevent hazardous impact of radioactivity by diffusing the radioactive waste (referred to hereinafter, as"diffusion type"); the method by which to prevent hazardous impact of radioactivity by disposing at land of
the solid radioactive waste whose radioactivity is expected to be significantly decayed in the course ofcontrol period, under step-wise control until it is fully decayed (referred to hereinafter, as "control type");the method by which to isolate the radioactive waste needed to be isolated for a long period of time safely
at the stable place physically apart enough from the human environment (referred to hereinafter, as"isolation type"); and the method by which to reuse or recycle the very low level radioactive waste to theresources, materials, etc. under certain conditions (referred to hereinafter, as "reuse type").
(5) To ensure the safety on the disposal of radioactive wastes, it is required to assess the safety of thedisposal method chosen, and to implement safety management based on assessment results. In the safetyassessment, it is essential to confirm that the disposal does not cause any hazards, evaluating the dose thatthe general public might be exposed through the food chain of radionuclides, originated from the disposalof the waste.

COMMENTARYThis basic concept was developed based on the features for the safety assurance of the waste repository
business as described below:(1)The concept of the safety assurance of the methods for the final disposal carried out as a waste
repository business is as provided in "the basic Concept of the Safety Regulation for Land Disposal of the
Low Level Radioactive Solid Waste" as mentioned above, i.e., the waste generated at nuclear facilities will
be disposed safely and necessary control shall be imposed of taking into consideration of the degree of
possible radiation exposures etc. to the general public until the reduction of the radioactivity is achieved sothat no further control is necessary.
(2) The control provided at the waste disposal facility is different from what has been provided in theordinary nuclear facilities, and it is possible to consider the change of control methods step wise inaccordance with reduction of the radioactivity etc.
Methods of the control in each step depend on the form and concentration of radioactivity of the waste,existence of installed engineered barriers, etc., and those are as shown below:(a) The case of disposal in engineered barriers type disposal facility
1) The first step
The peripheral monitoring area shall be established to limit entry to the area, and the repository
preservation area shall be established to implement patrol and inspection in the area.
In addition, no leakage of radioactive materials from the engineered barriers installed in the waste disposal
facility shall be confirmed by monitoring leakage of radioactive materials etc., and necessary measures,such as the repair, shall be taken when leakage is confirmed.
2) The second step
The peripheral monitoring area shall be established to limit entry to the area, and the repository
preservation area shall be established to implement patrol and inspection in the area.
In addition, the underground water etc. shall be sampled and measured to monitor the concentration ofradioactive materials leaking from the engineered barriers and migrating to the human environment.
3) The third step
The repository preservation area shall be established to implement patrol and inspection in the area, and thespecific acts such as farming works etc. in the area shall be restricted or prohibited.
(b) The case of disposal in non-engineered barriers type disposal facility
1) Disposal step
Annex1-114

The peripheral monitoring area shall be established to limit entry to the area, and the repository
preservation area shall be established to implement patrol and inspection in the area.
In addition, the underground water etc. shall be sampled and measured to monitor the concentration ofradioactive materials migrating from the waste disposal facility to the human environment.
2) Preservation stage
The repository preservation area shall be established to implement patrol and inspection in the area, and thespecific acts such as farming works etc. in the area shall be restricted or prohibited.
Therefore, the safety evaluation of the waste disposal facility during the control time period shall be
implemented with due considerations of the above described methods of step-wise control and functional
degradation of the equipment installed in the waste disposal facility according to the progress of time.
(3) In addition, as the waste repository business is planned to move to the step which does not needmanagement or control finally after the step wise control described above, it is necessary to examine at thetime of business application, and to obtain the prospect on the possibility to move to the situation which
does not need management or control after the stepwise control with in the limited time span.

From a viewpoint to avoid a big accident and to mitigate the effect of the accident, it is necessary toconfirm that the safety is assured taking into considerations of the following events at the site of the waste
disposal facility and the surroundings:(1) Natural environmenta) Natural phenomena, such as the earthquake, tidal waves, landslide, cave-in, typhoon, high tide, flood,abnormal cold wave, and heavy snowfall,b) Geology, geographical features, etc., such as the subsoil, bearing capacity of soil, geology of faults andtopographic features,c) Meteorological conditions , such as the wind direction, wind speed, and amount of precipitation, andd) Hydraulics and hydraulic phenomena such as the river, underground water, etc.
(2) Social environmenta) The fire, explosion, etc. in the neighbor factories etc., andb) Usage of the river water, underground water, etc., land usage situations, etc. for foods, such as
agriculture, livestock raising, fishing, etc. and the population distribution, etc.
c) Natural resources, such as the coal and ore
4 On Dose Evaluation(1) Evaluation for Normal Conditions
The radiation dose of the general public due to leakage or migration of radioactive materials from the waste
disposal facility, release of the radioactive gaseous and the liquid waste, etc. from the associated facilitiesof the waste disposal facility, etc. at normal conditions shall be evaluated and confirmed not to exceed thedose limit specified in regulations, and be evaluated and confirmed to be as low as reasonably achievable atthe planning and design of the step-wise control, in relation with the conditions of the site and its vicinity.
(2) Safety Evaluationa) Since the business continues over a long period of time, the radiation dose of a general public shall be
evaluated technically assuming unusual leakage or migration of radioactive materials from the waste
disposal facility. This evaluation is for the purpose to confirm the safety assurance to the general public,
even in such an event as exceeding the event considered for normal conditions.
b) The possibility of occurrence of the following accidents shall be examined at the associated facilities of
the waste disposal facility, and the radiation dose of the general public shall be evaluated on the selected
Annex1-115

accidents considered to be important from a viewpoint of the exposure of the general public:i Scattering of radioactive materials accompanied by dropping of wastes by operational error etc.;
ii Leakage of radioactive materials caused by damage of piping etc., failure of various equipment, etc.;andiii Fire etc.
c) When measures for mitigating the effect is taken against the accident, the radiation dose of the generalpublic due to the radioactivity leaked, migrated and release during the accident shall be evaluated taking into account of time delay till the detection of abnormality, time necessary to mitigation work completion as
appropriate.
d) "No excess radiation exposure to the general public" means in consideration of the balance of frequency
and the magnitude of accident consequences, and the decision criteria shall be "no excess risk of radiation
exposure to the general public", the application to specific situations shall be based on the followings:
According to the 1990 recommendation of the revised ICRP, the annual effective dose limit to the
publicexposure is recommended to be 1mSv, but in a special situation, the effective dosage of one single year
higher than this limit may be permitted if the average over five years does not exceed 1mSv per year.
Although it is a concept of the radiation exposure in normal times, this concept may be applied to"accident" if the frequency of occurrence is small, and the "risk" can be judged to be small provided thatthe evaluated value of the effective dosage of the general public does not exceed 5mSv per specificaccident.
5 On Radiation Control"Disposal step" means the time period from the start of disposal activities until the covering soil isstabilized.
6 On Design Considerations for Earthquakes and Natural Phenomena other than Earthquake"Appropriate time period" means the time period of the first step for the waste disposal facility, and it is therequired time period for proceeding the waste repository business appropriately for the associated facilitiesof the waste disposal facility.
In addition, "preserve required safety functions" means to preserve confinement function etc. for the waste
disposal facility.
7 On Termination of Control Time Period(1) In the case of disposal in engineered barriers type disposal facility, from 300 to 400 years shall be usedas the guide value of "the limited time span", as the amount of Cobalt-60, Cesium-137, etc. which aremajor part of radioactivity and important from radiation protection views, in the waste generated at reactor
facilities decays less to 1/1000 or 1/10,000 of initial during this time period, and similar time periods forthe waste disposal facility are referred in foreign countries. In addition, in the case of disposal in
non-engineered barriers type disposal facility, about 50 years of the disposal step and the subsequent
preservation step shall be used as the guide value of "the limited time span", as non-solidified concrete, etc.
are disposed wastes which radioactivity level is low by nature.
(2) "Radiation dose so low as the control is not required from a viewpoint of the exposure control" meansthat the evaluated value of the radiation dose not exceed the regulation exclusion dose, 10micro-Sv per year,
as the guide value, which is specified in the report by the Basic Committee of the Radiation Review
Council, "On the Regulation Exclusion Dose in the Near Surface Disposal of Radioactive Solid Wastes",
December, 1987.
In addition to, the evaluated value of the radiation dose not exceeding 10micro-Sv per year extremely shallbe the guide value for the event possible to be considered that the frequency of occurrence is small.

3. Calculation of Clearance Levels
3.1 Basic Concepts for Calculation of Clearance Levels
Basic concepts for calculation of clearance levels is shown with respect to each subject in sections
3.1.1 through 3.1.5, and the arranged procedure for calculation based on the concepts is shown in Fig. 3-5of the final section.
3.1.1 Basic Concepts for Calculation Methods
Clearance levels for solid wasted materials in the main reactor facilities (i.e. light water reactors andgas cooled reactors) was determined to be obtained by calculation according to the following methods asprovided in the IAEA technical document, “TECDOC-855”:(1) The guide values of radiation dose shall be established with consideration of superposition of practices,evaluation routes, etc. with a target as “doses which is sufficiently small compared with the radiationlevel of the nature, and the risk to human health can be disregarded”; and(2) Concentrations of radionuclides corresponding to the guide values of dose shall be calculated according
to the following prerequisites.
a) Clearance levels shall be unconditional where the use or destination of the material are not limited
after removed from the system of regulations concerning radiation protection (referred to hereafter, as“cleared”).
b) All the evaluation routes shall be considered (for disposal or reuse) assumed to be occurred actually
due to the evaluation item. The probability of occurrence shall not be taken account as a conservative
approach, because it is not appropriate to assume the probability of occurrence since the use or
destination of the cleared evaluation item is not limited.
c) The minimum concentration shall be determined for each radionuclide by calculating theconcentration according to the evaluation route using realistic parameters for the evaluation item. And
the evaluation route that gives the minimum concentration is specified as the “Critical Route”.
The IAEA technical document, “TECDOC-855”, provide clearance levels obtained by comparing andexamining information of published references. In Japan, on the other hand, it is decided that clearance
levels shall be calculated on the basis of circumstances of the daily life, social environment, etc. in Japan,
and that the dose evaluation of existing nuclear facilities (e.g., dose evaluations for the general public in thevicinity of low-level radioactive waste disposal facilities, commercial power reactor facilities etc.) shall bealso referred.
3.1.2 Application Criteria of Radiation Doses
The application criteria of radiation doses from which clearance levels is calculated shall be as
sufficiently low so that anyone of the neighboring public surrounding a nuclear facility does not receive
radiation exceeding the individual dose limit (i.e. 1 mSv/year, excluding the radiation dose received fromthe nature) specified by regulations. Moreover, the application criteria shall be sufficiently low as notneeded to take consideration of protection from the radiation, as the radiation dose caused by the clearedmaterial is “sufficiently small as compared with the radiation level by the nature, and negligibly small inrisk to the human health”.
In order to satisfy the above mentioned concept, the guide value of radiation doses from whichclearance levels is calculated has been established as follows with references, “Regulation Exclusion Dosefor the Near Surface Disposal of Radioactive Solid Wastes” prescribed by the Radiation Review Council in
1987, and “Fundamental Concepts for the Safety Review of Radioactive Waste Disposal Facilities”
prescribed by the NSC in 1988, and references by ICRP, IAEA, etc.
(1)The application criteria for individual radiation dose based on realistic scenario (referred to as“scenario” that is combinations of evaluation routes and evaluation parameters) is determined as 10µSv/year (0.01 mSv/year: less than one-hundredth of the averaged radiation level of the natural
background of 2.4 mSv/year) with consideration of superposition of human behavior, evaluation routes,
Annex1-117

etc., that is one-tenth of 100 µSv/year (0.1 mSv/year) which is equivalent to the risk level that any
individual might consider as negligible (10-6/year).
(2)Although the probability of occurrence of evaluation routes shall not be taken account as a conservative
approach in the estimation of clearance level for unconditional usage and destination of cleared material,
but the lower limit value of the 97.5% tail of one side confidence interval (Refer to chapter 4) bycombination of parameters considering the fluctuation of evaluation parameters (probabilistic analysis)
shall be treated as one of “ low probability scenario”, and the individual radiation dose for this scenario
shall be confirmed not exceeding 100 µSv/year, which is the same as specified n the IAEA technicaldocument “TECDOC-855”.
3.1.3 Evaluation Candidates
The concept of critical group shown by ICRP etc. is important as a fundamental concept to selectevaluation candidates and evaluation parameters in calculating clearance levels. The concept of criticalgroup is as follows, which is also adopted as a reference in the IAEA technical document“TECDOC-855”;- Select a group of members who receives the highest radiation dose caused by the evaluation items.
- Select a homogeneous group. (One representative of the group is modeled in evaluation.)- Select typical values as for the behavior of daily life, etc., and select representative values as formetabolic parameters.
The clearance levels were determined based on the calculations selecting a homogeneous group,
which represents those individuals who receive the highest radiation dose in realistic scenarios, as
evaluation candidates, referring to the pre-described concept for critical group shown by ICRP etc.,
reports of this Special Committee, “Reference Values for the Safety Regulation of the Land Disposalof Low Level Radioactive Wastes (Interim Report and Second Interim Report)” (December, 1986, andFebruary, 1992) (referred to hereafter, as “the Report on the Government Ordinance Concentration
Limit Value”) in which the upper limits on radioactive material concentration in radioactive wastes(referred to hereafter, as “the Government Ordinance Concentration Upper Limits”) were derived, bywhich the license of waste disposal business can be applied under Article 13-9 of “the Ordinance for
the Enforcement for the Regulations of Nuclear Source Material, Nuclear Fuel Material and Reactors”,
and the License Application for the Radioactive Waste Disposal Business of the Rokkasyo Low-Level
Radioactive Waste Disposal Center by Japan Nuclear Fuel Limited (hereafter called “low level
radioactive waste disposal facility application”), etc.
3.1.4 Evaluation Items(1) Type and Amount of Evaluation Items
The type and amount of evaluation items in this report are based on the type and estimatedamount of wastes etc. generated by the decommissioning and operation (referred to hereafter, as“decommissioning etc.”) of major nuclear facilities (light water reactors and gas cooled reactors).
The estimated amount of wastes etc. to be generated by decommissioning one unit of 1,100 MWclass boiling water reactor (BWR) or pressure water reactor (PWR), or a 160 MW gas cooled reactor(GCR) is shown in Table 3-3.
Major parts of wastes etc. considered to be below the clearance level are those of metals andconcretes (including thermal insulators etc.) among wastes etc. generated by decommissioning, andthe amount is, for example, assumed as 530,000 tons for BWR (including wastes etc. according to thereport, “Fundamental Concept of Wastes of Non-Radioactive Wastes” by this Special Committee inFebruary, 1992).
As to these wastes etc., it is assumed for evaluation that metals and concrete will be reused anddisposed of in the same manner as industrial wastes, respectively, as shown in Fig. 3-1.
Combustible wastes shall not be included in the items for this evaluation.
Since the IAEA technical documents, “TECDOC-855” etc. describe that the clearance level shallbe calculated for each practice, it has been decided that the clearance level shall be calculated basedon the estimated amount of wastes generated by decommissioning of one unit of commercial powerreactor facility, specified as one practice in this case.
Accumulation of practice likedecommissioning two or more units of commercial power reactor facilities is already taken into
consideration since the application criteria of radiation dose is established as one-tenth of 100µSv/year.
Since the amount of wastes etc. to be generated by decommissioning of research reactor
facilities (excluding heavy water reactors and fast neutron reactors) and by operation of main nuclear
facilities (i.e. light water reactors and gas cooled reactors) is very small compared with that of wastes
etc. generated by decommissioning of commercial power reactor facilities, it can be regarded asincluded for evaluation in the amount of wastes etc. generated by decommissioning of commercial
power reactor facilities. (Refer to Attachment 4-1 and Attachment 4-2)
(2) Selection of Typical Radioactive Nuclides
In calculation of the clearance level, twenty (20) radioactive nuclides considered to be
representative for radiation dose evaluation were selected of the radionuclides important for the
Annex1-118

following purposes;- Since the wastes etc. generated by decommissioning of reactor facilities etc. may contains
radionuclides from secondary contamination due to adhesion, penetration, etc. of reactor coolant
etc. and from activation by neutron beams of reactor, these radionuclides shall be evaluated.
- In decommissioning of a nuclear facility, safe storage period after the reactor shutdown isprovided for about five to ten years before dismantling and removal starts, and short half-lived
radioactive nuclides shall be decayed sufficiently before the waste repository disposal or reusestarts. Therefore, short half-lived radioactive nuclides are neglected from the scope ofevaluation items.
- Those radioactive nuclides, whose concentration is provided in the Government OrdinanceConcentration Limit Value and those specified in the application for the low level radioactive
waste disposal facility, shall be taken into consideration.
- The radioactive nuclides described in the IAEA technical document, “TECDOC-855” shall betaken into consideration for reference. However, as some of those radioactive nuclides describedin TECDOC-855 are supposed to exist in facilities other than nuclear reactors, such nuclides
having short half-lives and small yields in nuclear facilities shall be excluded from consideration.
When the application criteria in order to institutionalize “wastes that do not need to be treated asradioactive materials” for major nuclear facilities (i.e. light water reactors and gas cooled reactors) , isdetermined radioactive nuclides which are relatively important in dose evaluations of solid materials(important radionuclides) will be extracted based on the calculation results of clearance levels and thecomposition of radionuclides in evaluation items, etc. This respect shall be discussed in Chapter 4.
3.1.5 Evaluation Routes(1) Evaluation Routes for Waste Repository Disposal
Evaluation routes for waste repository disposal are selected referring the Report on Government
Ordinance Concentration Limit Values and Application for the Low Level Radioactive Waste Disposal
facility, etc.
The evaluation routes which are taken into consideration in the calculation of clearance levels
must be selected so that all the evaluation routes assumed to occur realistically after wastes werecleared should be included comprehensively, based on the actual conditions and the regulations on
handling and transportation of wastes to disposal facility, the regulations on industrial waste
repositories, actual conditions of the repository, natural conditions in the vicinity, social environments,
and daily life of general public, etc. But, it is not necessary to cover all the routes in the calculationof clearance levels, clearance levels can be evaluated by selecting representative routes which areconsidered to be comprehensive. That is, the routes to be evaluated will be selected by removing suchroutes that radiation doses can be judged to be neglibibly small compared with those of other routes
even if without performing dose evaluation, and evaluation results are included in those of other routes,
under the prerequisites described bellow.
Although the probability of occurrence is considered to be different for each evaluation route, it
was decided not to take the probabilities into account as a conservative approach, because it is not
appropriate to assume probabilities by identifying natural conditions and social environments in thecalculation of unconditional clearance levels of the materials of which uses or destinations are notlimited.
[Prerequisites]
a. Evaluation starting time of the cleared wastes shall be when the wastes are shipped from a nuclear
facility, after certification of the waste is completed, and confirmed to be below the clearance level.
b. The wastes generated by decommissioning of a nuclear facility are concrete and metal materials,
and assumed to be disposed of to the disposal facility of similar structures to “stable type disposal
facility” for industrial wastes, as such assumption is considered to be a conservative approach for theevaluation purpose since the migration of radioactive nuclides to the groundwater is large in case ofsuch type disposal facility.
c. Reclamation disposal (including water surface reclamation disposal) and sea disposal are carriedout in Japan as methods of waste disposal. Among these methods, the sea disposal is forbidden for
metal rubbish, construction debris, etc. according to the provision of Article 6, Section 1 of “theOrdinance for Enforcement of Law on Processing and Cleaning of Wastes”. Eighteen (18) of total
2,636 facilities for the reclamation disposal are sea surface reclamation disposal facilities, and the rest
are inland reclamation facilities as of April, 1993. (Handbook of Industrial Waste Processing, 1996)
In view of these circumstances, the inland reclamation disposal and the sea surface reclamation
disposal shall be subject to the evaluation as disposal methods, since the inland water surface
reclamation will not be carried out as a stable type disposal.
d. Since other site conditions of repository cannot be specified, natural environments and social
environments of other disposal sites shall be comprehensively assumed.
e. The evaluation routes shall be selected assuming that the site will be used after the completion
Annex1-119

of disposal and closure of the disposal facility.
The selected evaluation routes by approaches as mentioned above for calculation of the clearance
levels (for waste repository disposal) are shown in Fig. 3-2. The evaluation routes subject to thecalculation are 41 routes selected comprehensively out of 125 routes. (Refer to Attachment-2.)
The evaluation routes selected at this time include all of the evaluation routes for waste repository
disposal specified in the IAEA technical document “TECDOC-855” excluding the routes for
combustible wastes.
The report, TECDOC-855 includes the selected evaluation routes of fire at disposal facility andincineration disposal considering the disposal of combustible wastes, but combustible wastes are notincluded in the present evaluation items for evaluation as indicated in Section 3.1.4 of this report.
(2) Evaluation Routes for Reuse
It is important for the evaluation for reuse to confirm widely the safety of reuse assuming various
possibilities with reference to the IAEA technical document, “TECDOC-855”. Consequently, theevaluation routes for reuse have been selected using the same method as used for waste repository
disposal to confirm widely the safety of reuse actually assumable.
The evaluation routes which are taken into consideration to calculate the clearance levels must be
selected so that all the evaluation routes assumed to occur actually are included comprehensively after
the materials are cleared, based on regulations and current status on handling and transportation ofwastes to reuse as final products, current status on recycle, production process and utilization form of
the products, and circumstances of daily life of general public, etc. But, it is not necessary to cover
all the routes in calculation of the clearance level. Some representative routes that are comprehensive
are selected and evaluated for the clearance level. That is, the routes which shall be evaluated has
been selected under the following prerequisites after removing the routes of which radiation doses canbe judged to be negligibly small compared with those of other routes without performing dose
evaluation, and the routes of which evaluation results are included in those of other routes.
Although the probability of occurrence is considered to be different for each evaluation route, it was
decided that the probabilities are not accounted for as a conservative approach, because it is not
appropriate to assume the probabilities by identifying the use specifically for calculation of theunconditional the clearance level of materials of which uses or destinations are not limited.
[Prerequisites]
a. The evaluation starting time of the objects by which clearance was carried out shall be the point oftime when the wastes are shipped from a nuclear facility after the certification of being below theclearance level is completed.
b. The evaluation routes for reuse shall be investigated separating conditions for the daily life and for theworking, hours and further, separating situations for processing the materials into reuse products and forreusing the products. Furthermore, reuse products shall be investigated by identifying each item afterclassifying the products into consumer goods and construction materials.
c. The reuse products shall be selected referring to the Survey Items of Main Consumer Durable Goods(Trends in Housekeeping Consumption, 1995, Research Bureau, Economic Planning Agency of Japan) as
items generally assumed, provided that the use conditions and the recycle conditions are considered to havecomprehensibility in consideration of purposes of use.
d. The reuse routes whose possibilities are extremely low, e.g., reuse of special materials, shall not beassumed. For example, the route to get on an airplane made of reused metals, or the route of medical
equipments made of reused materials shall not be assumed.
e. The case of local radiation exposure caused by reuse of the material for a wrist watch or a belt
buckle shall not be selected as the evaluation route, since the effect to the whole body is small as sizeof the source is small.

1. Evaluation Items for Certification
Evaluation items for certification are solid materials mainly generated by decommissioning of major
reactor facilities (light water reactors and gas cooled reactors). And the materials are metals and concrete(including heat insulation materials).
2. Categories of Classification of Evaluation Items
For the judgment that the evaluation items are below clearance levels, the evaluation items are classified
as follows with consideration of the possibility of contamination by both activation and secondary
contamination:(1) The evaluation items that have the possibility of contamination by either activation or secondary
contamination(2) The evaluation items that evidently have no possibility of contamination by activation or secondary
contamination
IV. Judgment for Materials to be below Clearance Levels
After classification of evaluation item, the judgment that the evaluation items are below clearance levels
shall be made by methods as shown in the followings.
1. Basis of Judgment for Materials to be Below Clearance Levels
The decision that the evaluation item is below clearance levels shall be made by confirming that either
one of the following two criteria (1) and (2) is met.
(1) The sum of concentrations of the radioactive nuclide ‘i’ of each evaluation items contained in the wastes
to be evaluated (D) divided by clearance levels (C) (referred to hereinafter, as “D/C”) is below one (1), i.e.
the following inequality is satisfied:“Sum of {(the concentration of radioactive nuclide ‘i’) / (clearance levels of radioactive nuclide ‘i’)} < 1(2) Activation contamination or secondary contamination does not exist evidently on the evaluation items.
2. Judgment by Sum of D/Cs of Evaluation Items to be Below One
The decision method by sum of D/Cs to be below one (1) is shown as follows as one of the basis for
decision that the evaluation item is below clearance levels.
2.1 Radionuclides for Evaluation
Nuclides for evaluation (referred to hereinafter, as “radionuclides for evaluation”) using the judgment bysumming D/Cs to be less than one (1) shall be the important radionuclides, i.e. H-3, Mn-54, Co-60, Sr-90,
Cs-134, Cs-137, Eu-152, Eu-154, and all alpha nuclides.
2.2 Determination of Composition Ratios of Radionuclides
Composition ratios of radionuclides shall be determined by the analyzed value of representative samples
for secondary contamination, and shall be determined mainly by calculation for activation contamination.
The representative samples shall be those in the range of evaluation items where the compositions ofradionuclides are the same, and shall be selected as appropriate representatives of the composition of theradionuclides in the range.
2.3 Evaluation Units of Concentrations of Radioactive Nuclides
Evaluation of concentrations of the radionuclides of the evaluation items for judgment to be made by
dividing the evaluation items into appropriate units depending on their shapes and dimensions. Less thanseveral tons of the weight are generally appropriate as a unit size for concentration evaluation ofradionuclides, but larger unit size may be adopted if the concentration of the radionuclides of the evaluation
items is homogeneous.
2.4 Judgment
Concentrations of radionuclides of the evaluation items shall be determined by the following methods forjudgment that the evaluation items is below clearance levels by confirmation that the sum of D/Cs ofradionuclides of the evaluation items is below one (1).
Concentrations of radionuclides in the materials of activation contamination and secondary
contamination may be determined by measurement. And in the case of activation contamination,
concentrations of radionuclides may be determined by a combination method of activation calculation andAnnex1-121

verification measurement of representative samples.
2.4.1 Judgment by Combination of Activation Calculation and Measurement for Verification
For the method by combination of activation calculation and measurement for verification,
concentrations of radionuclides by activation shall be obtained by activation calculation and theconcentration of important radionuclides shall be measured for respective sample to verify the calculated
values. For activation calculation, general computer codes such as ORIGEN may be used. Parameters forthe calculation shall be determined as follows:
Density distribution of neutron fluxes
The density distribution of neutron fluxes shall be determined by calculation (neutron transportation
calculation), by combination of calculation and measurement, or by measurement. When the distribution isdetermined by calculation, appropriate distribution shall be used with considerations of the pastexperiences.
(2) Element composition
Element compositions are determined by using analytical values, standards, or referenced documents.
(3) Irradiation histories
Irradiation histories shall be obtained from the past irradiation histories of each plant. When theevaluation items are dismantled parts of a plant, the elapsed time of dismantling after reactor shutdown may
be considered.
The measurements of radionuclides concentrations for the verification of the calculation results shall be
performed in accordance with “Section 2.4.2, Method to Determine the Radionuclides Concentration by
Measurement”.
2.4.2 Methods to Determine Radionuclides Concentrations by Measurement

Methods of measurement to determine the concentration of radioactive nuclides for the evaluation item areshown in (1), the selection of measuring device for radioactivity and the determination of measuringconditions is shown in (2), and the selection of the measuring points are shown in (3).
(followings are omitted)
3. Judgment for Evaluation Items not Contaminated Evidently
Any of those materials may be judged to be below clearance levels by confirming the classification isappropriate, if the evaluation items are classified as “materials not activation contaminated and notsecondary contaminated evidently”. For confirming the classification, it is necessary to evaluate withviewpoints of both activation contamination and secondary contamination do not exist, and the principle of
Paragraph 3.1 and Paragraph 3.2 are applicable as described in “the Second Interim Report”.
3.1Judgment Criteria for Evaluation Items are not Activation Contaminated Evidently(1) Concrete wastes (including contained steel reinforcements etc.)
The evaluation items corresponding to any of the following 1) to 3) may be classified as “materials not
activation contaminated evidently” as a whole:1) The materials evidently unnecessary to consider the activation effect by neutron beams from structural
viewpoint of the facility such that it was shielded with enough radiation shielding materials;
2) The materials evaluated by calculation etc. that there are no meaningful differences of the effect ofneutron activation from the general concrete materials; or3) The materials evaluated by calculation etc. that some parts of the material are meaningfully different in
the effect of neutron activation from the general concrete materials and are removed the activated parts.
(2) Metal wastes
The same principles as mentioned in (1) above may be applied.
3.2 Judgment Criteria for Evaluation Items is not Secondary Contaminated Evidently
The evaluation items corresponding to any of the following 1) to 2) may be classified as “materials notsecondary contaminated evidently” as a whole;1) The materials that are evidently not secondary contaminated by adhesion or permeation of radioactive
materials judging from the histories of usage or conditions of installation; or2) The materials that evidently the spreads of secondary contamination by adhesion or permeation ofradioactive materials are restricted judging from the histories of usage or conditions of installation and areremoved the contaminated parts.

2. The Principles of Calculation of Clearance Levels for heavy water reactors, Fast neutron reactors,
etc.
Solid materials generated at the major reactor facilities (light water reactors and gas cooled reactors)
were selected as evaluation items for clearance levels investigation in the “Clearance Levels Report”, basedon the following reasons: 1. For reactor facilities, there are experiences of rule making on safety criteria etc.
concerned to disposal of low level radioactive waste and their applications, 2. For reactor facilities,
contents and compositions of radionuclides are relatively homogeneous as the radioactive materials are
originated by neutron activation, 3. For light water reactors and gas cooled reactors, various kinds of data
are accumulated.
On solid materials generated at heavy water reactors, fast neutron reactors, etc out as the evaluation
items, the investigation was carried on since March of 1999.
This investigation was carried on using the evaluation methods used in the “Clearance Levels Report”
with due consideration of the difference between heavy water reactors, fast neutron reactor etc. and the
major reactor facilities (light water reactors and gas cooled reactors), because the evaluation items of heavy
water reactors, fast neutron reactor etc. are solid materials and the composition of the nuclides etc. isrelatively homogeneous, that is similar to the evaluation items of the main reactor facilities (light water
reactors and gas cooled reactor). In this investigation, clearance levels to be applied for heavy water
reactors, fast neutron reactors, etc. were calculated after surveying of classification of evaluation items andtheir quantities from those reactor facilities, and the standard values based on the calculation results were
derived.
3. Calculation of Clearance Levels
For calculation of clearance levels to be applied for heavy water reactors, fast neutron reactors, etc.,
Paragraph 3.1 of Chapter 3, ”Calculation of clearance levels” of “clearance levels Report” was followed,
and “application criteria of radiation dose” and “evaluation candidates” are regarded as equivalent to thereport, and types and quantities of wastes generated by decommissioning and by operation of the reactor
facilities were evaluated after surveying on heavy water reactors, fast neutron reactors, etc. Based on the
results, differences from clearance levels of light water reactor and gas cooled reactors were investigated as
the followings.
3.1 Types and Quantities of Evaluation Items(1) Wastes etc. generated by decommissioning etc. of heavy water reactors
The estimated quantities of the wastes etc. generated by decommissioning of the heavy water reactor,“Fugen”, are as shown in table 1-1. Wastes etc. estimated to be below clearance levels are mostly metals
and concrete. The estimated quantity is about 360,000 tons (including wastes etc. according to the report,“Fundamental Concept for Wastes of Non-radioactive Wastes” by the old Special Committee in February,1992), and there are no big differences in the quantity and the types of wastes from those generated bydecommissioning of commercial nuclear power reactor facilities.
Wastes considered below clearance levels among the wastes generated by decommissioning of the heavy
water reactor, ”JRR-2”, are mostly metals and concrete, and the quantity is estimated to be about 300 tons(including wastes etc. reported in “Fundamental Concept for Wastes of Non-radioactive Wastes” by the oldSpecial Committee in February, 1992). As “JRR-2” is a reactor facility of 10MW thermal output, thequantity of wastes generated is very small as compared with that by decommissioning of commercial powerreactor facilities.Therefore, the quantity of wastes for evaluation is regarded as included in that generated
by decommissioning of commercial power reactor facilities. The difference is that the heavy concrete
containing barite (the main component is BaSO4) of coarse aggregate is used for the biological shield that is
not used for light water reactors or gas cooled reactors.
(2) Wastes generated by decommissioning of fast neutron reactors
The estimated quantities of the wastes etc. generated by decommissioning of fast neutron reactor, “Joyo”,
Annex1-123

are shown in Table 1-1. Wastes etc. estimated to be below clearance levels of the wastes generated bydecommissioning are mostly metals and concrete, and the quantity is estimated to be about 280,000 tons(including wastes etc. reported in “Fundamental Concept for Wastes of Non-radioactive Wastes” by the oldSpecial Committee in February, 1992), and there are no big differences in quantities and types from theestimated quantities of wastes generated by decommissioning of commercial power reactor facilities. The
difference is that the graphite shield material is used around the reactor vessel.
And, as enough shields are provided around the core and as the core size of “Joyo” is small, the weightof “wastes of Non-radioactive wastes is estimated larger and the weight of clearance evaluation wastes (thewastes whose activity level is below clearance levels and excluded the Non-radioactive wastes, the same
terminology is used, hereinafter) is smaller as compared with that of light water reactors or gas cooled
reactors.
For the fast neutron reactor, “Monju” which is under construction, the total quantity of wastes etc. isestimated to be about three times of the wastes etc. from “Joyo”, as a result of approximate evaluation of
the quantity of generated wastes etc. based on the evaluation for “Joyo”, which is because the facilities arelarger and the steam generation system and the power generation system are added as compared with
“Joyo”. However, the weight of “Non-radioactive wastes” is estimated large and the weight of clearance
evaluation wastes is small accordingly, that is similar to “Joyo” as described above, and it is included forevaluation.
As the quantity of wastes etc. generated during operation of heavy water reactors and fast neutron reactors
are very small as compared with the amount of wastes etc. generated by decommissioning, the quantity of
the wastes etc. is regarded as included in the wastes generated by decommissioning for evaluation.
(3) The wastes etc. generated by decommissioning of other reactor facilities
For reactor facilities such as criticality facilities etc. other than the heavy water reactors and fast neutron
facilities, same evaluation process can be applied as the materials of main components are similar to thoseused for heavy water reactors or fast neutron reactors, and as the radioactive materials are originated mainly
by neutron activation, and the radioactive nuclides and their composition are relatively homogeneous.
For criticality facilities, the quantity of wastes is regarded as included in the quantity of wastes generated
by decommissioning of above mentioned reactor facilities for evaluation as the amount of wastes etc. are
estimated to be very small as compared with the wastes generated by decommissioning of the above
mentioned reactor facilities
3.2 Representative Radionuclides
Twenty (20) radionuclides and Ba-133 are selected which are considered to be representative in theevaluation of radioation doses for the calculation of clearance levels of heavy water reactors and fastneutron reactors, as calculated in the “Clearance Levels Report” based on the following reasons.
- The same materials as used for light water reactors are used for heavy water reactor, ”Fugen” basically,
though the core structure is different. And the types of radioactive nuclides of the wastes etc. generated
at the heavy water reactor, “Fugen” is basically the same as those generated at light water reactors
because the materials used for the heavy water system are similar to those used for light water
reactors.
- For heavy water reactor, “JRR-2”, the same materials as used for light water reactors are used basicallyas used for the heavy water reactor, “Fugen”. However, as the heavy concrete containing barite (themain component is BaSO4) of coarse aggregate is used as the main body of biological shield, thebuild-up of Ba-133 by activation shall be considered.
- For the fast neutron reactor, “Joyo” and “Monju”, the same core materials are used as used for lightwater reactors basically except the coolant (sodium). And, the effect of thermal neutron is dominant at
structures, materials and clearance items outside of the reactor vessel as light water reactor, though theneutron spectrum is harder and the density of the neutron flux is higher in the reactor core of fastneutron reactors than those of light water reactors. Generation of C-14 by activation of the graphite
shielding installed outside of the reactor vessel of “Joyo” shall be considered, but C-14 is included in
the twenty (20) radioactive nuclides considered to be representative for evaluation of radioactive dose
calculated in the “clearance levels Report”.
3.3 Evaluation Routes, Calculation Models and Evaluation Parameters
As described in Paragraph 3.1 and Paragraph 3.2, the types of wastes etc. and their quantity generated bydecommissioning of heavy water reactors and fast neutron reactors is not largely different from those of themain reactor facilities (light water reactors and gas cooled reactors) except that additional consideration to
be taken on the effect of Ba-133 for heavy concrete used for the biological shield of heavy water reactor,“JRR-2” which contain barite (main component is BaSO4) of coarse aggregate and the effect of C-14 forthe graphite shielding installed outside of reactor vessel of fast neutron reactor “Joyo”. Therefore, the sameevaluation routes, calculation models and evaluation parameters as shown in “clearance levels Report” canbe selected basically. Comparison of the evaluation parameters and results of investigation about the types
and quantities of wastes generated at the light water reactors and gas cooled reactors versus heavy water
reactors and fast neutron reactors are shown in the Table 1-2. For Ba-133 that was added as a new item forinvestigation, evaluation parameters are selected about nuclide-element dependent parameters.

Facilities
2. Basic Concepts of Measures for Safety Assurance
For decommissioning of a reactor facility, it is important to provide measures to prevent the effect ofradioactive materials to the peripheral environment, since radioactive materials remained in the reactor
facility are dealt with. For this reason, it is important to adopt construction methods to prevent
appropriately the radioactive material to diffuse out of the facility and also it is important to make efforts tomaintain and to utilize the existing barriers, filter equipment, etc.
There are sufficient experiences of radiation protection for the occupational personnel who works inthe nuclear reactor facility through replacement of core shrouds which is a construction work of theequipment of highly activated core internals, and through replacement of steam generators which is alarge-scale construction work of the equipment of high radioactive material concentration. Therefore, it isimportant that measures for radiation protection are selected and implemented appropriately depending
upon the characteristics of decommissioning works fully based on the knowledge acquired from such
experiences as described.
Moreover, it is indispensable that detailed processing and disposal methods, disposal facility andstorage places are established in advance of the dismantling and removal works, as radioactive wastes are
generated by dismantling and removal works of reactor facilities. Furthermore, at the actual dismantling
and removal works, the wastes shall be classified according to the concentration and characteristics ofradioactive materials contained and the processing and disposal of the wastes shall be carried out inappropriate manners. And also, it is important to grasp exactly the flow of wastes from the generating
places to the disposal facility.
Prior to these decommissioning, it is inevitable to confirm the prospect for assured implementation of
decommissioning by planning the whole decommissioning program, since the operation of the wholedecommissioning continues over a long period of time. After that, a more detailed plan for each step should
be drawn up prior to the execution of individual decommissioning work, so that assured implementation of-planning of the concerned dismantling and removal works in the site where other reactor facilities are in
operation, it is required to consider its effect on these facilities.
The separate sheet provides considerations comprehensively arranged on the safety assurance basedon the basic concept of the above-mentioned safety assurance.
3. Main Discussion Subjects
The main subjects selected from the above discussions were as follows.
(1) Dividing Decommissioning Plans
Since decommissioning is construction activity extending to a long period of time and technicalprogresses in the meantime are expected, it is not necessarily rational to make the detailed planning about
the whole processes of decommissioning works at the beginning. For this reason, the details of
decommissioning processes should be admitted to be divided and to be decided later step by step. Thoughdecommissioning converts a facility into safer conditions by dismantling and removal works, unstableconditions, such as loss of shielding function or release of radioactive dust, etc., might occur occasionallyin the processes. For this reason, it is important to secure the prospect of decommissioning to be carried out
steadily and continuously prior to decommissioning.
Therefore, it is considered to be acceptable to make a decommissioning plan specifying the outline ofthe project to secure the prospect covering the whole processes in the overall projects at the beginning, andAnnex1-125

to decide detailed plans one by one prior to the start of each process taking in the newest knowledge. In thiscase, it is divided into three processes of system decontamination, safe storage, dismantling and removal inconsideration of the highly activated or contaminated equipments as a standard (refer to Figure 1). When
there is a process not included in these three processes (for example, a prior dismantling process during thesystem decontamination process or the safe storage process), it can be expected to secure the prospect ofsteady implementation of decommissioning by additional sufficient explanation about the concerned
process in the overall plan (refer to Figure 2).
(2) Prior Dismantling of a Part of the Facility
The standard process provided in the report of the Nuclear Advisory Committee in 1985 is based on
the concept that the whole facility is at first decontaminated and successively kept in stable storage
conditions, and then the dismantling and removal is carried out. However, the part of the facility that has noactivation or no contamination, or has the low activation or contamination can be disassembled without
system decontamination or without safe storage period to attenuate radioactive material. Therefore, it ispossible to accept to carry out the prior dismantling of the facility when highly activated and/or
contaminated parts of the facilities are under system decontamination or under safe storage.
However, it is necessary to satisfy the following requirements in this case.
a. Prevention of bad effects on the facilities under system decontamination and safe storage
Bad effects on the facilities under system decontamination and safe storage shall be prevented andmanagement of the concerned facilities shall not be interrupted limiting the scope and methods of priordismantling.
b. Management during the prior dismantling
In order to carry out the prior dismantling safely, radiation control, maintenance and control of the
facilities, preventing propagation of contamination, etc. shall be carried out.
c. The safety assurance after the prior dismantling
The facilities shall not be in the un-safe condition after the prior dismantling by limiting the scope andmethods of the prior dismantling.
d. Radioactive disposal
Radioactive wastes generated by the prior dismantling shall be possible to be stored and disposed ofappropriately.
e. Release of radioactive materials
The total amount of discharged radioactive materials shall not be significantly increased by the priordismantling.
f. Reservation of funds
Sufficient funds shall be remained for the subsequent processes after the prior dismantling.
(3) Completion Time Limit for Decommissioning
Unlike new constructions, the expense for decommissioning work cannot be recovered later. Moreover,
if the nuclear reactor facility were left indefinitely, degradation of the retarding the radioactive material
migrating to environment and of the shielding function would occur, and the hazard caused by the facility
would be expected
From such a viewpoint, it is supposed to be important that decommissioning should be appropriately
completed within a certain time period.
The time period for decommissioning works by the above-mentioned three processes of systemdecontamination, safe storage, and dismantling and removal takes about fifteen (15) to sixteen (16) years asprovided in the report of the Nuclear Advisory Committee in 1985. Therefore, it is considered as the firstprospect, that the time period until completion of decommissioning works is about 30 years referring to the
new knowledge. In this case, even if taking consideration to include terms for operation and fuel removal,
etc. prior to decommissioning works after shut-down, it is considered that the preventing function ofradioactive materials migrating to outside of the facility and the shielding function of the concrete walls
remain in sound until completion of decommissioning.
When it is expected that decommissioning works cannot be completed in about 30 years due torelating restraints with other reactor facilities in the site, individual measures are necessary to be verified
for the safety assurance in such conditions.
4. Basic Concepts for Safety Regulation
The government agencies need to appropriately apply the regulations (Notification of the DismantlingPlan, the Safety Preservation Rules) specified by the present legislations and regulations so that nuclear
business operators can implement the safety assurance measures for their decommissioning assuredly. The
government agencies need to assure exactly the methods and the processes relating to decommissioning
according to the Notification of Dismantling Plan, and the safety preservation management andorganization such as the maintenance management of facilities, radiation control and disposal according to
the Safety Preservation Rules.
On the other hand, in view of continuation of decommissioning works for a long period of time, it isnecessary to accept the nuclear business operator, as above-mentioned, to make the whole plan ofdecommissioning and the detailed plan required for the time being at the beginning, and to make detailed
Annex1-126

plans one by one according to the progress of decommissioning. It is considered to be appropriate for the
purpose to realize implementation of the rational and effective regulations that the government agencies to
execute such a practical application as to implement regulatory procedures corresponding to one by oneplanning (partial acceptance of the detailed plan of the Notification of Dismantling Plans) (refer to Figure
2).
Moreover, it is necessary to change the Safety Preservation Rules when the management rules such as
the area management, the facility management, etc. are changed according to the progress of
decommissioning, and also the government agencies should correspond appropriately to such changes.
