Chapter 1 Background
The National Institute for Fusion Science (below as NIFS) was established in 1989 as aninter-university research institute, and utilizes the Large Helical Device (below as LHD) as theprincipal device to advance fusion research in universities in Japan.
The LHD, which was planned by bearing the support and the expectations of the fusion
community, has the special characteristic of producing the heliotron-type magnetic field, which is anidea unique to Japan. In addition to generating high-performance helical-type plasma through highpower heating, NIFS is advancing with experimental research that aims to clarify physical andtechnological issues for realizing the toroidal magnetic field confinement fusion reactor. On the other
hand, parallel with this, in analyses of fusion plasmas having fundamental complexities, theoreticalresearch that uses large-scale simulations are essential. For that reason, a supercomputer for exclusive
use was introduced at NIFS. We are advancing with leading-edge research by making thissupercomputer at NIFS available for use to fusion theory researchers in Japan through collaborative
research. Moreover, since 2010, in order to further strengthen the centripetal power of NIFS as a Centerof Excellence (below as COE) in the field of plasma and fusion research we have organized threeresearch projects, these being LHD, theory and simulation, and reactor engineering. Looking forward
toward achieving the fusion reactor, initiated research programs will integrate these research results.
In addition to having revised the research structure within NIFS and having placed all
research staff in one research department, by establishing a research system that enables participation
by free will in research projects and has enabled easier cooperation in the three projects of LHD, theory
and simulation, and reactor engineering than in the past, we are increasingly able to respondresourcefully to new topics.
In this period, there have been changes to the structure of the domestic academic researchsystem. Since 2004, NIFS has been a research institute under the Inter-University Research InstituteCorporation National Institutes of Natural Sciences (below as NINS) for enhancing further thedomestic research collaboration. Upon becoming an inter-university research corporation, a system
for mid-term goals and mid-term planning spanning six years was introduced, and a system of annual
evaluations regarding the progress, too, was introduced. This annual evaluation focuses primarily uponadministrative management. However, at NIFS it has been determined that receiving external
evaluations of research results is important. Under the NIFS Advisory Committee, each year anExternal Peer Review Committee is organized, and the members evaluate the research. The topics ofevaluation are determined by the Advisory Committee. The evaluation is undertaken by the membersof the External Peer Review Committee, which is composed of experts who are external members of
the Advisory Committee and external experts who are appropriate for evaluating the topics. The
External Evaluation Committee submits its evaluation results to the Advisory Committee. Then, NIFS,-1-

together with making the results public by uploading that information to the NIFS homepage, utilizes
this information to improve research activities in the following years.
The topics for evaluation for the External Peer Review Committee are discussed and decided
upon by the Advisory Committee, and those topics for evaluation differ each year. Most recently, in2017 the Reactor Engineering Research Project, in 2018 the Large Helical Device Project, and in 2019
the Numerical Simulation Reactor Research Project were topics evaluated by external reviewers. This
year, 2020, the “Division of Health and Safety Promotion”, the “Division of Information andCommunication Systems”, and the “Division of External Affairs” were selected and reviewed by theexternal examiners.
As external members of the External Peer Review Committee there were ten external
members from the Advisory Committee and three members from foreign countries. Further, there were
three experts from outside NIFS. Thus was the External Peer Review Committee composed, andthereby the evaluation was undertaken.
The first meeting of the External Peer Review Committee including the Experts’ Committee
was convened on October 2, 2020. The Committee discussed the process for moving forward with thisfiscal year’s external peer review, and decided upon the perspective of the evaluation. On November
24, 2020, the second meeting of the External Peer Review Committee and Experts’ Committee washeld. From NIFS was provided a detailed explanation that utilized documents from the material of
viewgraphs and reports based on the perspectives (see the documents section). A question-and-answer
session also was held. Subsequently, the third meeting of the External Peer Review Committee andthe Experts’ Committee was held on January 26, 2021. Together with holding another question andanswer session with NIFS, evaluation work based on the topics of the evaluation and the coordinationof the evaluation work were undertaken. We compiled the external peer review report (draft) based
upon the discussions to this point, and further discussions were held by electronic mail. Upon
confirmation and examination by the External Peer Review Committee and the Experts’ Committee,
we compiled the final report on March 2021.
Moreover, in the external evaluation regarding NIFS’s “Division of Health and Safety
Promotion”, the “Division of Information and Communication Systems”, and the “Division ofExternal Affairs” which were implemented this fiscal year, the perspectives for the evaluation were
determined as follows. The perspectives for the evaluation consist of all the aspects that are
indispensable in evaluating the performance of NIFS's “Division of Health and Safety Promotion,” the“Division of Information and Communication Systems,” and the “Division of External Affairs.”-2-

Chapter 2 Summary of the Evaluation, and Recommendation
We summarize the key points of the evaluation, and report in writing the recommendation regarding
promotion of NIFS’s “Division of Health and Safety Promotion”, the “Division of Information andCommunication Systems”, and the “Division of External Affairs”.

[1] Summary of the Evaluation
1. Division of Health and Safety Promotion(1) Are the organizations and systems for safety and health management properly constructed
and operated in compliance with relevant laws and regulations?
At the National Institute for Fusion Science, many large-scale equipment such as LHD,
liquefied helium-related equipment, and high-power power supply equipment must be
operated at the same time, and the radiation control system including tritium must be operated
with an emphasis on safety. The Division of Health and Safety Promotion has 10 rooms
consisting of administrative staff, technical staff, and research staff, and has created a close
cooperation system in charge of specialized fields. You comply with many safety-related legal
compliance operations and are working with a high level of awareness to create a safe
environment.
It is important to continue efforts such as collecting and disclosing cases of hiyari-hatto (nearmiss accident), preparing disaster prevention manuals, compiling and revising safety
handbooks, safety seminars, and safety patrols. We hope that the current activities thatmaintain high motivation for health and safety will continue to be developed.
Although the management and operation system has been properly established under theDivision Director of health and Safety Promotion, we expect that we will strive for continuous
safety and health management, such as taking measures such as strengthening support asnecessary.
(2) Are the safety management equipment / facilities, experimental equipment, etc., formaintaining and managing safety taken into account for the characteristics andcircumstances peculiar to fusion research?
As a fusion research device, safety management and operation related to radiation handlingare emphasized in LHD-related fields. After the deuterium experiment is started, management
and operation at an extremely high level is required, such as activation of equipment due toneutron generation and prevention of environmental exposure of tritium. Under the Division-4-

of Health and Safety Promotion, radiation level monitoring and necessary management
equipment are being developed, and it can be judged that this is a sufficient response,
including on-site gate management within the laboratory.
Regarding radiation control, a third-party committee has been set up to measure radiation
regularly. The transparency of information is guaranteed outside the laboratory.
Environmental radiation in the surrounding area is measured regularly and reported to thearea. In addition, the number of people who have acquired qualifications related to radiation
control is increasing, and you are actively conducting educational activities within the facility.
These things can be highly evaluated.
In safety management of high power, high voltage, cryogenic temperature, high pressure gas,
heavy objects, etc. required for fusion research as well as tritium and neutrons, thecharacteristics and circumstances are fully considered and appropriate measures are taken.
It can be highly evaluated.
(3) Are manuals and rules such as operation manuals, radiation control manuals, and emergency
manuals properly formulated and operated?
Safety-related rules and response manuals for disasters have been properly formulated. It is
operated with guarantee of continuity, such as not being able to participate in experiments
and equipment installation without taking a seminar every year. Considering the actual use of
the manuals, the minimum required items are summarized on pages 1-2, which can be referred
to on the Web, etc. In addition, there are some ingenuities in terms of operation so that it isalways checked in daily driving. From these things, it can be highly evaluated.
As the Inter-University Research Institute, outside researchers including foreigners also havethe opportunity to handle the equipment. The maintenance of these manuals is indispensable
for building a safe experimental environment, and you are properly formulated and operated.
From these things, it can be highly evaluated.
Foreigners are also considered for the route display signs of emergency evacuation routes,
and sufficient measures are taken against emergencies.
(4) As the Inter-University Research Institute, do you properly provide safety management andeducation to staff and collaborators?
Not only faculty and staff inside the institute, but also many people such as collaborators
outside the institute and employees of related companies are participating in the operation of
the equipment managed by the National Institute for Fusion Science. In order to build a safe
and secure working environment for the entire site, it is indispensable to build a safety andhealth management system and safety education. In addition to an appropriate health and-5-safety management system, you also give consideration to safety education not only for staff
but also for collaborators and those who belong to companies involved in equipment
installation and operation. From these things, it can be highly evaluated.
We expect continuous improvement, such as reflecting the opinions of staff and collaboratorsand responding to the increase in foreign researchers. It is also worth considering imposing asimple test on the participants of the seminar.
(5) Is the training of leaders to carry out safety management properly planned andimplemented?
In order to properly comply with the law and operate the safety management system, it isnecessary to train leaders who have qualifications in accordance with the law, such asradiation protection supervisor. Continued support to staff, encouraging the acquisition ofnational qualifications such as 27 first-class radiation protection supervisor’s license holders,
50 license holders related to high-pressure gas handling, and 25 first-class health officer’s
license holders. The training of instructors who carry out safety management is systematically
implemented and can be highly evaluated. We hope that you will continue to strive to develop
human resources involved in health and safety management.
Human resource development requires a long-term strategy, and we look forward to future
measures such as conducting regular checks and reviews on scenarios for training andsecuring the necessary personnel in the future.
2. Division of Information and Communication Systems(1) Is the information and communication system as a research platform properly constructed
and operated?
It is extremely commendable that the information and communication system andinformation network (NIFS-LAN), which form the basis of the institute’s activities, have been
appropriately constructed and are being safely managed and operated. In particular, three
types of networks (NIFS-LAN, LHD-LAN, and PS-LAN) have been constructed and arebeing operated with special attention to security, and appropriate responses to incidents havebeen taken. In addition, it is highly evaluated that the institute has established a system tosupport research activities as a major research institute in the field of fusion science in Japan,
including the establishment of an information system for joint researchers and ateleconference system.
(2) Is the division of information and communication systems properly responding to requests
for information system development from inside and outside the institute?

-6-

It is highly evaluated that the division of information and communication systems is
responding appropriately to the development of information systems in response to requests
from both inside and outside the institute, including support for the storage and managementof large-scale experimental data, development of data transfer technology, software license
management, and development and operation of various information processing systems suchas the international conference participation registration system. On the other hand, this is aposition that requires specialization, and organization needs to continue to take measures toensure that the workload in not too unevenly distributed among some staff members.
(3) Is the organization of the division of information and communication systems functionallyconstructed and operated?
Within the division of information and communication systems, task groups and operation
teams have been organized and are operating appropriately. In addition to providing a single
point of contact for system development, the task groups enable the exchange of technicalinformation and cross-checking between tasks, which is highly evaluated as a way to enhanceservice response. On the other hand, considering the high level of expertise and responsibility
in the business, it is expected that the institute will continue to manage labor appropriately byallocating personnel appropriately.
3. Division of External Affairs(1) Do you provide information and have a dialogue on the importance and the safety of fusion
research for the development of a sustainable society to a wide range of people?
In addition to conducting facility tours, open campus, public academic lectures, Fusion Festa,
public explanatory meetings, small group training sessions for SSH-designated schools, andother outreach activities for a wide range of people, the NIFS continues to disseminate
information on the importance and safety of fusion research through the Web, newsletters,
SNS, and press releases. This is highly commendable. Further continuation and developmentof online activities, which will become more important in the future, is expected.
(2) Do you carry out community interaction activities appropriately to gain their trust andunderstanding of fusion research through communication with local residents?
Through the implementation of public explanatory meetings (341 times over 15 years),participation in local events, publication of PR magazines, etc., the Institute has maintained
communication with local communities and residents, and has vigorously engaged incommunity exchange activities to gain the understanding of local residents. It is highly
commendable that the NIFS has gained a better understanding of activities of the institute-7-

from the local community. Activities aimed at further building trust are expected while
maintaining communication with citizens.
(3) Do you contribute to the science education of children, students, and society through various
workshops and events?
It is highly commendable that science education activities in a broad sense, not limited tonuclear fusion and plasma, are being conducted for a wide range of citizens, frompreschoolers to elementary school students, junior high school students, high school students,
and adults, utilizing various forms such as science handicraft workshops, delivery classes,
work experience, internships, and public academic lectures according to age groups. In the
future, it is expected to promote communication activities with an overseas perspective, while
responding to the shift to online activities, such as the enhancement of video content.

Chapter 3 In Closing
Since 2010, in order to further strengthen the centripetal power of NIFS as a COE in the fieldof plasma and fusion research we have organized three research projects, these being LHD, theory andsimulation, and reactor engineering. Looking forward toward achieving the fusion reactor, NIFS has
initiated research programs that will integrate these research results. Moreover, the research structure
at NIFS was reorganized and all academic researchers have now been placed in one research
department. They may now participate in any or all of the three research projects by their choice. Dueto this, we anticipate the promotion of links with LHD, theory and simulation, and fusion engineering,
and we anticipate being able to respond resourcefully to new topics.
In the NIFS External Peer Review Committee review, in 2017 the Reactor Engineering
Research Project, in 2018 the LHD Project, and in 2019 the Numerical Simulation Reactor Research
Project were evaluated. Thus, in this current year of 2020 the Advisory Committee undertook an
external evaluation that focused on NIFS’s “Division of Health and Safety Promotion”, the “Divisionof Information and Communication Systems”, and the “Division of External Affairs”. The ExternalPeer Review Committee was composed of ten members of the Advisory Committee outside of NIFS
and three members from abroad, and, as the experts, three members outside of NIFS.

Roles
The main role of this office is to check the safety of experimental devices
other than LHD. For this purpose, researchers who want to setup new
experimental apparatus must apply for the safety review. Two reviewers are
assigned from members of this office and other specialists. They check thesafety of these devices.
・ Examine new experiments for safety problems and advise on safetymeasures.
* New experiments in LHD are reviewed by the LHD Experiment Group.
・ Improve safety in each experiment and reinforce the safety culture at NIFS
by annual reviews by users. Therefore, each device needs to be applied for(updated) every year.

Followings are basic way of thinking to the deuterium experiment safety
at an emergency and a disaster.
1) Minimize the quantity of occurring tritium.
2) Limit the quantity of tritium remaining in a VV which does not exceed
the management level, even if a gross quantity is released.
3) Keep the management level of the radiological generations, such as
Ar-41, which have a possibility to give influence on the environment.
4) Pay attention severely to a leak of the recovered water.

and the internet is controlled by a firewall. Network Operation TG provides the Guest
Network, which is segmented by NIFS-LAN, for guest researchers to access the internet
easily. Wi-Fi is serviced only on Guest Network.
Edge switches on the building are connected to Core switch with 2 10Gbeps lines for
redundancy. The single-mode optical fibers are laid between buildings. Most of the metal
cable in the building is replaced from Category 5 to Category 6 to ensure the connection
with 1 Gbps.

• is ESET Endpoint Protection standard from June 2020.
• Monitoring servers check the PC states on NIFS-LAN and LHD-LAN.
• Symantec Endpoint Protection had used for a long time, but the
product distribution was unstable since Symantec was buyout.

• Firewall• connects NIFS-LAN and the internet to control the inner and outerconnections.
• distincts Web sites which staff access and block some URL for
security.
• detects the application on the connection and disconnect some
application for security.

Mail Service• Mail service on NIFS has migrated from MailSuite, anintegrated mail software, to Google Gmail on September 1st ,2020.
• Motivations of the migration:• Maintenance term of MailSuite will be end at this financial year.
• Request from staff that mail service should be up 24x7 is hard.
• It needs to overcome the power outage due to legal inspection.

• IP reputation of mail server is so low that sometimes the mail is not
accepted as our mail server might seemed to be used by spammer.

• On the migration term, the forward configuration was setup
to the mail could be received on both MailSuite and Gmail,the staff of NIFS could migrate to Gmail on the term.
• No major problem was occurred on the migration term.
14

Mail Service (2)• 2-Step authentication is mandatory because of the
security trend.
• MailSuite had customized to use 2-Step authentication.
Onetime passwd (OTP) cards were used.
• YubiKey, small USB-connect authentication device,
have distributed to all the staff of NIFS.
• SMS or authentication app on smartphone ispermitted to use.

• All the migration process are done by the administrator, not user.
• Account setting• Mail Spool on MailSuite• It takes more than a week. Number of account is about 400, and number ofmail to migrate is about 4 million.

• ML• ML, members of ML, and the detail configurations.
• More than 40 configuration is there on Google Group.
• Setting tools for Group configuration is not provided by Google, so small
handmade programs written by Google Apps Script to call Admin API was
used.
15

LHD-LAN• LHD experimental LAN, LHD-LAN is dedicated tocarry out the LHD experiment. It is separated from
NIFS-LAN by FW.
• The PC on NIFS-LAN cannot directly reach LHD-LAN,an access-gateway server, which checks the security
condition of PC and password authentication ofuser, controls whether PC can reach the LHD-LAN
or not.
• LHD-LAN consists several segments, control sub
cluster is separated by FW.
• Wifi is prohibit on LHD-LAN for security, Wifi on
Guest Network is prepared in the control room.

Outside research collaborator
can access LHD-LAN via
Remote access server on NIFSFW, SSL-VPN server, which
requests 2-Step authenticationand checks the terminal's
security condition.

17

Network infrastructure development forguests/collaborators• User authentication system for remote access service• NIFS information network is protected from external accesses by afirewall system. In order to conduct collaborative works, we provides aremote access service by use of an SSL-VPN device. For better security,
we impose multi-factor authentication.
• The SSL-VPN device providing a remote access service was replaced in2015. The prior system employed the RSA SecurID®. In FY 2014, the NIFS
mail system has been replaced, which also impose multi-factor
authentication using a one-time password (OTP) card by DAOU corp. In
order to reduce the total cost of ownership, we developed anauthentication system coupled with DAOU OTP authentication based on
free-radius and mysql.

• Eduroam based wireless LAN service• A wireless LAN service for guests under Eduroam was deployed in FY
2018. The system is supported by inner and outer radius servers
coupled with mysql user database, and we have distributed accesspoints (Aps) covering common area such as a meeting room andaccommodation facility. APs are managed by the centralized controller.
18Institutional information systems supporting
NIFS and the fusion research community• NIFS Collaboration Database System: Nicollas• “Nicollas” was newly designed and developed in 2013 to be used for the
online submission and judgment of the NIFS collaboration applications
for FY. 2014, and had been continuously bug-fixed and functionally
improved. In Nov. of 2017, this system was renewed as the NINS open
use system (NOUS) in which most of the Nicollas codes have been
ported with the original functionalities.

• NIFS-Repository• Institutional Repository (IR) is recognized as one of the most important
infrastructures for universities and institutes. The first system for NIFS
Repository based on “DSpace” started its operation in Mar. of 2009 by
RIO. It was transferred to the institutional information systems task
group (IIS-TG) in Apr. 2013 and ported into the “JAIRO Cloud” operated
by National Institutes for Informatics(NII).

19

Institutional information systems supporting
NIFS and the fusion research community (Contd.)• NIFS Article Information System: NAIS
• “NAIS” accumulates information ofresearch achievements made by NIFS
staffs and the collaborators for more thanten years. This system had been operated
under Research Information Office (RIO)
since April of 2006. In Apr. of 2013, it has
been transferred to the institutional
information systems task group (IIS-TG).
• This system has been continuously
improved under a collaboration with the
Research Enhancement Strategy Office(RESO). This system is used not only foraccumulating research products, but for
an internal approval for publication /presentation. It becomes one of essential
information systems supporting research
activities in NIFS. The total number ofregistered records in Nov. of 2020 is about
17,000.
20

Distributed Data Storage System• Many advanced diagnostics are
installed on LHD. Huge amount ofdata should be stored safely.
• GlusterFS is selected for the
distributed storage system by its
scalability and by the fact thatrecovery of the file system is mucheasier that the previous system.
H. Nakanishi et. al., Fusion Engineering and Design 89 (2014) 707–711

21

Generation of analyzed data

Dependence of physical parameters• To obtain physical parameters, the AD converted binary data
should be processed to the physical parameters.
• The dependence of the physical parameters is quite complicated.
“AutoAna” system automatically resolves the dependency andgenerating analyzed data representing physical parameters.
• After developing the AutoAna system (2016), registered analyzed
data increased drastically.

Operation and Maintenance of NIFS Atomic
and Molecular Database• NIFS Atomic and Molecular(AM) Numerical Databases
provide AM data on
elementary processes
important in fusion plasmas
and other various plasmas forusers via internet for free.
• Data are updated regularly.
• The server has moved to DMZ
from NIFS internal network forsecurity reason in 2016.
• The database system wasreconstructed in a new
replaced server with using
PostgreSQL and Ruby on Rails
in FY2016 to be more securesystem.

New “simple search” query system for AM
database• “Simple search” system is developed for easier use in
2016. It allows users to find target processes anddata more easily than before. Other problems in theolder system were fixed as well.

25

Implementation to VAMDC• Virtual Atomic and Molecular Data Center (VAMDC) is operated
by international consortium and provides web portal to accessvarious AM database at once and to present data according to
XSAMS (XML Schema for AM data). AMDIS-ION is now
implemented to VAMDC since 2018. We have developed
additional system and new tables to connect to VAMDC.

26

2．Response to requests for information system from inside andoutside the institute・Is the division of information and communication systems
properly responding to requests for information systemdevelopment from inside and outside the institute?

License investigation for Microsoft products• NIFS was asked to conduct license
investigation by Microsoft Corp. inFeb. of 2015. Since the number oftargeted devices is about 3000, wedeveloped a web app for inquiry
and counting.
• Using the app, NIFS reported theresult of license investigation to
Microsoft Corp. in Jun. of 2015.
• It took about 1 month to develop
the app and 2 weeks for inquiry.
Total man-hour cost was 3.5 MM,
which consists of 1 MM for app
developing, 1.5 MM for inquiry, 1
MM for hearing investigation andreporting. NIFS recognized such aninvestigation as a heavy burden anddecided to contract Microsoft
campus license in Oct. of 2016.
28

Contraction of Microsoft campus license• Since the license investigation asked by Microsoft Corp. was relatively
high cost, NIFS contracted Microsoft campus license in May of 2017.
As our main needs was a desktop office application and NIFS was asmall institution, we chose OVS-ES plan.
• In order to conduct an adequate license management, we installed a
MKS server and distribute a customized installer package forMicrosoft office product via an internal web site with a user
authentication.
• In May of 2020, NIFS changed the license plan from OVS-ES to EES. To
adapt the EES, we established a regime for user administration underAzure Active Directory. On the ramp-up period, existing user account
was exported from the email system operated by the NetTG andimported into Azure AD via a web interface and customized with useof PowerShell script.
• Now we provides a cloud-based applications such as Microsoft Teams
as well as a desktop office product. A large number of NIFS members
are satisfied with the situation.
29

Infrastructure for information disclosure
to research collaborators• ID provider for research collaborators: Colid• Disclosure of information required for collaborative research isimportant task. In order to keep proper confidentiality, an Identity andaccess management (IAM) is required. The NIFS Collaboration Database
System “Nicollas” had provided IAM functionality. Since Nicollas stopped
its operation in 2017, we became to need an alternative IAM system.
• The Integrated ID management and Authentication System Task Group(IDMAS) built a new IAM system for research collaborators in FY 2017.
We launched the identity provider for NIFS collaborators Colid in Apr. of
2018. As a base software we employed shibboleth IdP, which is widelyused in the Accademic Access Management Federation in Japan(GakuNin).
• Since collaborative research is adopted and updated every year, user
account information in Colid is initialized and newly adopted researchcollaborators are exported from NOUS and imported into Colid. In orderto establish a proper segregation of duties, this user import/export
procedure is performed by the Research Support Division in the
Department of Administration.

• Functional enhancement on LHD web site for collaborators
30

Support system for conferences/workshops• Icarus• “Icarus”, deployed in July of 2013, is a web-based online service forassisting various host operation to hold international conferences, which
is developed on Ruby-on-Rails. It provides general functionalities
required for organizing international conference, such as online
registration; abstract submission, review, selection, and notification;
electronic account settlement via credit card for registration fees andother optional ones; online subscription for related event participation;and so on.
• This system is utilized in international conferences hosted by NIFS,
which are held once or twice in each year. The detailed workflow may
differ for each conference, we made a customization in response to theneed of a conference organizer.

• Workshop• The “Workshop” hosting support service, deployed in June of 2015, hasbeen developed by intensive requests from the NIFS collaboration
caretakers. Answering some configuration inquiries, the workshop
caretakers can automatically build their own websites with necessary
online functionalities, such as participant registration. This system has
been constantly used by about 10 workshops every year.
