Atomic Energy Society of JapanThe 12th General Meeting Proposal 1
Business Report for FY2021
Taking seriously the fact that the nuclear community in Japan was unable to prevent the accident at theTEPCO's Fukushima Daiichi Nuclear Power Station (TEPCO Fukushima Accident), the Society, in
accordance with the Articles of Incorporation revised in 2013, continues to place the safety of the public
above all else and to advance the science and technology of nuclear energy and radiation in peacefulpurpose. We have been promoting the utilization and dissemination of the results of our activities,
thereby contributing to the preservation of the environment and the development of society.
With regard to the decommissioning of the Fukushima Daiichi Nuclear Power Plant, we are engaged in
activities to make academic proposals, etc., mainly through the "Fukushima Daiichi Nuclear Power Plant
Decommissioning Review Committee (Decommissioning Committee)". In addition, we have continued
the activities of the "Fukushima Special Project" and have actively promoted support for residents in thesurrounding areas, symposiums, etc., in cooperation with the national government and related domestic
and international organizations. In FY2021, from the perspective of preventing the transmission of newcoronavirus, we are planning to establish an environmental restoration plaza (former Environmental
Restoration Plaza) to support understanding activities regarding environmental restoration, interim
storage, radiation, etc. in Fukushima. However, On the other hand, we continued to exchange
information with NPOs and provide cooperation and support for school education in Fukushima
Prefecture as part of our cooperation for the revitalization and reconstruction of Hamadori, which
remains a difficult-to-return zone, which we started last fiscal year. We will continue these activities in
the future, taking into account social conditions and other factors.
In the area of annual meetings and congresses, due to the impact of the new coronavirus, the Fall 2021
and Spring 2022 Annual Meetings were held online, respectively, and many sessions were planned andorganized, resulting in a successful event. In addition, we made the program and proceedings available
to the public via Confit, and provided information services to participants.
In the area of awards, we presented the Society Award, Fellow Award, and Section and Chapter Awards,
and awarded the title of Fellow to members who have made outstanding contributions to the developmentof the Society, as well as special commendations.

Activities to improve the efficiency of the Society's operations, to improve its financial situation, and tomaintain and increase its membership have continued under the leadership of the Special Division forManagement Improvement, which reports directly to the Board of Directors. In order to promote thedissemination and utilization of the results of academic and technical surveys and research conducted by
the Society, we considered the establishment of a new alumni system. This system will be launched infiscal year 2022 to provide objective information and opportunities to interact with experts to as many
people as possible who have some interest in nuclear energy, as well as to stimulate interest in theSociety's activities and increase membership. In addition, we started round-table discussions with themass media to actively disseminate information and exchange opinions.
Compared to the previous year, the number of regular members decreased by 181 to 5,707, educational
members remained unchanged, student members increased by 4 to 439, and supporting members
decreased by 5 companies and increased by 5 units to 201 companies and 924.2 units.
The following is a report on the FY2021 business.

1. Academic and technical research on peaceful uses of nuclear energy, research and establishment ofstandards for peaceful uses of nuclear energy(1) Academic and technical surveys and research
We established the Research Expert Committee, the Survey Expert Committee, and the Special Expert
Committee, and continued to conduct academic and technical surveys and research on peaceful uses ofnuclear energy. From the viewpoint of preventing the spread of the new coronavirus, many of these
activities were conducted through online conferences, etc. Annual reports were prepared and publishedin the journal, on the website, and in lectures and reports at the annual meeting and conference.



Study of methods to promote understanding of the safety case for geological disposal among various
stakeholders (Chief Director: Takayuki Sasaki, 10 members)(2) Fukushima Daiichi Nuclear Power Plant Decommissioning Study Committee
The decommissioning of the Fukushima Daiichi Nuclear Power Plant is an extremely long-term project
involving unprecedented technical challenges. In 2014, the "Fukushima Daiichi Nuclear Power Plant
Decommissioning Study Committee" (hereinafter referred to as "Decommissioning Committee"; Chair:
Hiroshi Miyano, Vice Chair: Naoto Sekimura, Koji Okamoto) was established to address this issue on along-term basis, make technical and professional contributions to ensure safe and smooth progress indecommissioning the accident reactor, and continue to follow up on the recommendations and issues
raised by the AESJ Investigation Committee. The Decommissioning Committee includes the Ministry of
Economy, Trade and Industry (METI), Agency for Natural Resources and Energy, the Nuclear Damage
Liability and Decommissioning Corporation (NDF), the International Research Institute of
Decommissioning (IRID), the Japan Atomic Energy Agency (JAEA), the Society of Chemical Engineers,
the Robotics Society of Japan and other organizations to facilitate discussion and information sharing.
The year 2021 marks 10 years since the Fukushima Daiichi accident and 8 years since the establishmentof the Decommissioning Commission. The Society held a symposium on March 11, 2021, to report on
the implementation of the lessons learned compiled by the AESJ Investigation Committee. Following
this, on June 12, the Decommissioning Committee held a decommissioning symposium "Challenges andProspects in the 10th Year of Decommissioning - Toward Safer Decommissioning -" on the web. The
symposium introduced the challenges and prospects in each field that the Decommissioning Committee
is working on, and invited commentators from the mass media and sociological researchers to engage ina broad exchange of opinions with society. In the activities of the divisions, the Waste Division (lead by
Satoshi Yanagihara) newly started to study the ideal way of waste volume management, the Robotics
Division (lead by Taku Yoshimi) discussed further deepening the use of robots in decommissioning, andthe Division on Strength Standards (lead by Shunichi Suzuki) discussed how structural strength
standards for accidental reactors should be developed.

In addition, the Decommissioning Committee held five meetings during the fiscal year as an activity for
information sharing and communication within the Society. Through these activities, we have received
information from the Agency for Natural Resources and Energy on the 1F decommissioning initiative,
from NDF on the issues in the "Strategic Plan for Decommissioning 2021," and from TEPCO on thestatus of ALPS treated water disposal. In addition, the FP Research Expert Committee of the Society
provided information on its activities in FY2021. At the fall meeting, under the theme of "Current Statusof Technological Development for 1F Decommissioning," JAEA introduced the Eichi Project and thestudy of debris generation process, and IRID introduced the current status of debris detection andremoval technology development. At the annual spring meeting, the activities of the various divisions of
the Decommissioning Committee were reported and discussed with members.
The Chairman presented certificates of appreciation to the recipients of the "Decommissioning
Contribution Award" established in FY2020 at the Decommissioning Symposium on June 12, 2021, to
those whose activities were particularly remarkable and deserving of the highest award.

(3) Activities of the Fukushima Special Project
The Fukushima Special Project was established in June 2012 to mobilize all of the Society's resources inrepairing the nuclear disaster caused by the TEPCO Fukushima accident from a local perspective. In
order to serve as an interface between the residents of Fukushima and the national government and theMinistry of the Environment so that they can return to their homes as soon as possible, we have been
providing necessary information accurately and in an easy-to-understand manner as a group of nuclear
experts from the standpoint of the residents. This year, we had planned to hold an exchange event inNamie Town and other locations, but decided to forego local activities in order to prevent thetransmission of the new coronavirus. Dispatch of experts to municipalities and the Environmental
Restoration Plaza (former Decontamination Information Plaza) has also been suspended. Rice
cultivation trials in Minamisoma City, which have been ongoing since FY2012, were conducted this year
as well, and we continued to investigate the behavior of Cs. As for activities to respond to the interests
and needs of local people, which were discussed last year as activities required for the project in the
future, we continued to exchange information with NPOs to support the revitalization and reconstructionof Hamadori, which remains a difficult return zone, and to cooperate with and support school education

in Fukushima Prefecture. In addition, we have been working with NPOs to support school education in
Fukushima Prefecture. As part of these activities, we also conducted a questionnaire survey of local
residents to determine whether the government's measures for reconstruction and revitalization of
Fukushima are meeting the expectations of local residents, and analyzed and summarized the results ofthe survey. These activities were reported at the fall conference in 2021 and the annual meeting in thespring of 2022.
(4) Establishment of Standards
In connection with the Fukushima accident at TEPCO, a new Nuclear Regulation Authority wasestablished and new regulatory standards went into effect in July 2013. In response to the establishmentof new regulatory standards and operational guidelines related to nuclear safety in Japan, the Standards
Committee has been reviewing the positioning of existing standards and examining the standards thatmust be newly established, and has been working on the backfit of the new standards, voluntary safety
improvement, severe accidents, safety improvement assessment and risk assessment, waste treatment
and disposal, and decommissioning. In addition, since the role of the Society's standards is to formulate
those related to "nuclear safety," the Society established the "Nuclear Safety Study Group" in FY2011 topromote analysis of the TEPCO Fukushima accident in cooperation with the Society's research activities
and to study the basic concept of "nuclear safety," and is conducting research and study activities that
contribute to the formulation of standards. The activities of the committee are as follows. Each activity
is widely disclosed at the planning lectures of annual meetings and conventions to contribute to thedissemination of standards and understanding of the activities.
In FY2021, four technical divisions (1) Risk, 2) System Safety, 3) Fundamental Application andDecommissioning Technology, and 4) Nuclear Fuel Cycle) formulated draft standards, and the Nuclear
Safety Study Group examined the basis of nuclear safety, which were discussed by the Standards
Committee (chaired by Mr. Yamamoto) and established as follows

Contributing

toFukushima

RecoveryandDecommissioning Promotion
In order to further effectively implement and promote activities contributing to Fukushima restorationand decommissioning, the Society made a proposal to academic associations with which it has contacts,
and on May 20, 2016, the "Association of Academic Associations Contributing to Fukushima Restoration
and Decommissioning Promotion" (hereinafter referred to as ANFURD) was established. ANFURD
serves as the executive committee, and currently 36 science and engineering academic associations areparticipating (http://www.anfurd.jp/). ANFURD aims to contribute to the post-accident reconstruction
and decommissioning of Fukushima by bringing together the wisdom of the academic associations anddisseminating information on the current situation and issues related to Fukushima and sharing
information among academic associations.
This year, in addition to the regular plenary meeting to share information and exchange opinions on
ANFURD's future activities, online seminars (6/12 and 1/18) were held as activities related to 1F treatedwater, one of the three important issues that this liaison group has identified as a challenge. In addition,
to include understanding of radioactive waste and its management, we conducted 13 weekly webinars
over a period of 3 months, which were well received. This webinar was a precursor to the weekly webinars
for divisions and liaison groups that will be held in FY2022, and we will pass on our experience and knowhow in the operation of these webinars.

6. Other activities necessary to achieve the objectives of the Society(1) Management Improvement and Member Service Improvement Activities
The Society continues to implement management improvement activities. As in the previous fiscal
year, travel and meeting expenses were reduced through the wide use of online conference, resulting ina nearly break-even financial statement for the current fiscal year. We will continue to actively promote
the use of online conferencing while paying attention to the revitalization of the society's activities.
In addition, we are working to maintain and increase the number of members in light of the recent
downward trend in membership. As a measure to reduce the number of senior members withdrawing
from membership, we plan to introduce a membership fee discount system from FY2022, and we madepreparations for the introduction of the system this fiscal year.

In addition, we are working to improve

member services in order to attract new members as well as keep them as members. As part of these
efforts, we identified current issues with the member login page on the website and organized items for
improvement. In addition, we have launched an information provision service via weekly webinars.
We have decided to establish a free registration alumni system starting next year, which will provide
objective information and opportunities to interact with experts to as many people as possible who havesome interest in nuclear energy, and we will also work to increase the number of members by stimulatinginterest in the activities of the Society.
(2) Public relations and information activities
In order to actively disseminate information to society, we issued a "Statement of Protest Against theRussian Military Attack on the Zabolitsiya Nuclear Power Plant in Ukraine" (March 4) and seven otherpress releases to inform the media of the Society's activities and other information. The President's Press
Conference, which coincided with the inauguration of the new President, the Fall Congress, and theSpring Annual Meeting, was held online rather than in person to prevent the transmission of the newcoronavirus. A new roundtable meeting between the President and the media was held (November 11)
to provide timely information to the press and promote exchanges. The Extreme Event Explanation Team
(Team 110), which provides explanations in response to requests to the Society from local governments
and the media, conducted normal activities in accordance with the guidelines established in FY2020. In

addition, the website operation working group studied the revision of the English website and decided
on a policy and specific process, while at the same time studying the structure of the member login pageand creating a test page in cooperation with the Member Services Committee. The Position Statement
Working Group examined ways to improve the system and structure for issuing PS, with the aim of
ensuring that PS is issued in a timely manner and with a clear message. We will continue to study
improvements, and after reviewing the regulations, we aim to implement the system in FY2022. In
addition, we actively implemented an e-mail distribution service for members.
(3) Planning Activities
In response to the follow-up to the recommendations of the Society's Accident Independent Investigation
Committee last fiscal year, we formulated regulations to review the Society's Code of Conduct at least
once every five years, and discussed ways to confirm the contents of the current Code of Conduct and topromote its penetration and dissemination, and organized future issues with the cooperation of the Boardof Directors. In addition, we discussed overarching responses to issues to be addressed by the Society
identified last year from the follow-up to the recommendations of the Society's accident investigation,
proposed the establishment of a task force to the Board of Directors, and contributed to the compilationof recommendations for future Society activities on a cross-organizational basis.
Furthermore, as part of its activities in the 10 years since the accident, the WG for the Future of Nuclear
Energy (led by Kenta Murakami), organized mainly by young and mid-career members of the Society,presented its final report, "Issues to be addressed to make nuclear energy more attractive andrecommendations for their solution.” In addition, the "Next Generation Information Dissemination WG(lead by Jun Nishiyama)," which was established in the same manner as the aforementioned WG, began
continuous outreach activities through video distribution using the Society's official YouTube"ATOMIRU" channel.
As in previous years, we planned and organized Board of Directors sessions at the fall meeting and thespring annual meeting. At the fall meeting, we discussed the direction of nuclear energy and our society
for the next era from both internal and external perspectives, against the backdrop of discussions on therevision of the Basic Energy Plan, as part of the "Re-thinking the Value of Nuclear Energy and the Role
to be Fulfilled by the Society" session. At the spring annual meeting, experts from within and outside theSociety discussed how to apply the Society's "knowledge" to the new energy index "energy well-being"
identified in the discussion, and panel discussions were held to deepen the discussion.
(4) Ethics Activities
The Ethics Committee has been working on the revision of the Code of Ethics in earnest since 2019,
taking into consideration the TEPCO Fukushima Daiichi Nuclear Power Plant accident, the KEPCO
money and goods transfer problem, the frequent quality fraud problems of manufacturers, and theorganizational culture issues common to these problems. Based on the opinions received from the public,

the Ethics Committee approved the final draft at the May 2021 in the Board of Directors meeting. The
revised Code of Ethics was made public on our website and published in our journals to inform ourmembers.
As a consideration of ethics-related issues, the nuclear security case of the TEPCO Kashiwazaki-Kariwa
Nuclear Power Station was taken up, and a discussion on fostering a nuclear security culture was held in
the planning lecture of the fall meeting in 2021. We decided to express our view as the Ethics Committee
based on this matter and proceeded with the discussion.
In the planning lecture for the spring annual meeting 2022, the discussion was based on a lecture fromthe perspective of wellbeing, which is the goal of positive ethics "oriented ethics".
In light of the 20th anniversary of the establishment of the Society's Code of Ethics and the Ethics
Committee in 2001, we are proceeding with the publication of articles contributed by experts on ethics
in the Society's journal (scheduled for one year from the December 2021 issue), and in the fall of 2022
we will hold a symposium to look into the future regarding ethical activities. Preparations are also
underway for a symposium on the future of ethics activities to be held in the fall of 2022.
We continue to follow up on issues related to ethics, such as the organizational culture of research
institutions and discussions using AI technology as an example, in light of changes in society.
We dispatched lecturers to member organizations' technical ethics training (7 times) and cooperated
with universities and other organizations by giving lectures at their request. We also continued toparticipate in technical ethics councils and other meetings to share information.
(5) Fellow System and Activities
The Society conferred the title of Fellow to regular members who have made outstanding contributions
to the development of the Society, in order to honor them and encourage them to contribute to thefurther development of the Society.
At the spring meeting in 2022, we held a ceremony to certify new Fellows and a "Gathering of Fellows,"
and gave a lecture titled "Japan's Nuclear Energy Policy and Current Situation. In addition, we supported
the participation fee for one student member to present at an international conference.
(6) Diversity Promotion Activities
A poster session was held at the fall meeting in 2021 as an attempt to build broad-based connections
beyond the boundaries of affiliation and occupation. Approximately 30 engineers and students working
in the nuclear field participated in the session. Although it was in web format, the poster session utilized
breakout rooms and provided an opportunity for everyone to gather and exchange ideas, resulting in

lively discussions and networking.
We participated in the "Girls' Summer School 2021" held online on August 8 and 9, 2021. This year, in
addition to the traditional poster and career counseling, we participated in an experimental event for the
first time as a society; with the cooperation of QST, we worked with young students on the various
functions of radiation using radiation cross-linked polylactic acid resin.
The Gender Equality Academic Society Liaison Committee actively participated in the steeringcommittee meeting and symposium, which were also held on the web, to investigate about genderequality activities of other organizations and to promote the efforts of our society.
The Committee's website was greatly improved in terms of readability, and in addition to posting activity
reports in a timely manner and disseminating information on related events, SNS was also introduced toactively disseminate information on the promotion of diversity.

Activities related to support for nuclear-related school education, support for engineer education, andsupport for nuclear human resource development in collaboration with related organizations in otherfields were continued.
The Division on Elementary and Secondary Education established the Textbook Survey WG, continuingon from last year, to conduct a survey of energy/environment- and nuclear-related descriptions in juniorhigh school social studies, science, health and physical education, and technology and home economics
textbooks edited based on the Courses of Study revised in 2017 and in use from FY2021, and submitted
a report to the Ministry of Education, Culture, Sports, Science, and Technology, textbook companies,etc.
In higher education, we collaborated with the Advanced Nuclear Energy Consortium for Future Society(ANEC) of the International Nuclear Human Resource Development Initiative of the Ministry of
Education, Culture, Sports, Science and Technology (MEXT), and planned the session "Toward theConstruction of a Cross-organizational Nuclear Education Infrastructure; International Nuclear Human
Resource Development Initiative Project" as the Education Committee at the spring annual meeting2022. Initiative Project" at the Spring 2022 meeting. In cooperation with the YGN and the Student
Liaison Committee, the committee requested notification of the Liaison Committee and other events to
the Council of Nuclear University Teachers.
With regard to engineer education, we continued our efforts to support the acquisition of professional
engineer qualifications through the Working Group for Supporting Preparation for the Professional

Engineer Examination, which was established in FY2019. Specifically, the working group members andtheir collaborators (volunteers) prepared explanations of the questions for the Professional Engineer
Examination conducted in 2021, and held the 12th Professional Engineer System and Examination
Seminar online in February 2022. In addition, we registered the programs recommended by thecommittees, divisions, and liaison groups of the Society as "Continuous Professional Development(CPD) Programs for Nuclear Engineers and Researchers" recommended by the Education Committee,
issued certificates in the name of the Education Committee Chairman to those who attended theprograms, and registered CPD achievements of our members. In FY2021, there were 9 registeredprograms, 129 certificates of implementation were issued, and 53 new registrants were registered. In
total, 1,095 certificates were issued and 648 people were registered, exceeding 10% of the total
membership. In light of the recent increase in the number of registrations, the Society is studying andexperimenting with ways to improve the efficiency of the CPD registration system. In addition, we arealso working to collaborate with related organizations by posting on the Society's website, distributing
AESJ news and other activities to increase the establishment and recognition of CPD, and participatingin the CPD Council.
As part of our efforts to promote sales of "Nuclear Energy Today and Tomorrow," a sister book to "TheCentury Opened by Nuclear Energy," which was published in October 2019 with a reprint of 2,000
copies, we awarded the 2021 Fellow Award winners (35) and student poster session winners (13 at thefall meeting 2021 and 14 at the spring annual meeting 2022) by providing the siter book as tje
supplementary prize.
The Network of Senior Members of the Society conducts dialogue activities with university students andothers who will lead the next generation in order to contribute to the transfer of technology and humanresource development. The Network makes every effort to prepare nuclear engineering students tobecome engineers who will be responsible for nuclear power in the future, to provide education students
with accurate guidance on energy, including nuclear power, and to help liberal arts students understandthe importance of nuclear power in their energy choices. This year, as in the previous year, most of thesessions were web-based, but the number of sessions increased from the previous year due to theimprovement of the dialogue environment. Seventeen dialogue sessions were held for the 24participating universities and technical colleges, and 360 students participated. As in the previous year,
we were unable to hold dialogues with educators (middle and high school teachers).
