Background

The National Institute for Fusion Science (NIFS) was established in 1989 as aninter-university research institute in order to promote fusion science research at universities throughusing the Large Helical Device (LHD) as the principal experimental device. The LHD, which was
designed with the collective opinion and the expectations of the fusion community, has the special
characteristic of generating the heliotron-type magnetic field, which is an idea unique to Japan, by
superconductive coils. And together with producing high-performance plasma through the helicalmethod via high-power heating, we are advancing with experimental research that aims to clarify
physical and engineering issues related to realizing the toroidal magnetic field confinement fusion
reactor. On the other hand, parallel to this, in the analysis of essentially complicated fusion plasma,theoretical research utilizing large-scale simulations is indispensable. At the National Institute for
Fusion Science we have introduced the cutting edge supercomputer (Plasma Simulator) for exclusive
use. And by providing collaborative use to fusion theory researchers in Japan we are advancing withpioneering research.

During this time, there have occurred changes in the system for academic research inJapan. From 2004, the National Institute for Fusion Science, as a member of the Inter-University
Research Institute Corporation National Institutes of Natural Sciences, pushed forward with joint use
and joint research projects. In having become a corporation, six-year mid-term goals and planningwere introduced, and a new system by which the Institute would undergo an annual evaluation
regarding progress was implemented. This annual evaluation focuses principally upon administrative
management, but at the National Institute for Fusion Science it was determined that receiving
evaluations from external experts regarding research results is important. The National Institute for
Fusion Science organized the external peer review committee under the Advisory Committee, and is
now conducting research evaluations annually. The topics for evaluation are decided upon at theAdvisory Committee, and the External Peer Review Committee is organized, which is composed ofexternal members of the Advisory Committee and external experts in the topics to be evaluated. The
External Peer Review Committee reports the evaluation results to the Advisory Committee, and the
National Institute for Fusion Science, respecting those results, utilizes them in improving the
research activities from the following year.

At the National Institute for Fusion Science, upon the beginning of the second period for
mid-term plan that began in 2010, in order to strengthen further the centripetal power of the National
Institute for Fusion Science as a recipient of a Center of Excellence grant (COE) in the field ofplasma fusion research, we have started research planning in three research projects, LHD, the1

Numerical Simulation Reactor Research, and Fusion Engineering Research. These projects will
unify results to date that focus on realizing the fusion reactor. For this purpose, in 2010 weundertook an internal reorganization of the research structure. In addition to incorporating all
research and education staff into one research department, a system which permitted personal choiceof participation in a research project was introduced. From this, the cooperation among the threeprojects of LHD, the Numerical Simulation Reactor Research, and Fusion Engineering Researchbecame much stronger, and we became more flexible in responding to new topics.

At the Advisory Committee, in order to confirm the results of the project system, theexternal evaluations were conducted first in 2011 for the LHD Project, in 2012 for the Numerical
Simulation Reactor Research Project, in 2013 for the Fusion Engineering Research Project, and thenin 2014 for the Deuterium Experiment Implementation Plan. Then, in 2015, under the subject“Numerical Simulation Reactor Research Project” the external peer review was undertaken. Then, as
external peer review committee members, ten external members of the Advisory Committee andthree foreign researchers were appointed, and, further, five domestic experts and two foreign experts
from outside the National Institute for Fusion Science were added. Thus was composed the external
evaluation committee, and this committee undertook the work of evaluation.

On October 21, 2015, at the First External Peer Review Committee and Experts
Committee Meeting there was consultation regarding how to proceed with this year’s external peer
review. There the issues for evaluation as well as the specific items for evaluation were decided.
Those details are found at the end of this chapter. At the Second External Peer Review Committee
and Experts Committee Meeting, which was held on November 28, 2015, the responsible leaders of
the National Institute for Fusion Science gave the committee members a detailed explanation by
utilizing viewgraphs and activity report documents (consult the Documents above) treating thesepoints of evaluation as well as evaluation topics. A question and answer session followed.
Subsequently, on January 20, 2016, the Third External Peer Review Committee and Experts
Committee Meeting was held,. Further discussion was held on evaluations that followed the points
and items that had been decided by the External Peer Review Committee and the Experts Committee,
and their compilation was undertaken. As a result, because a general agreement had been achieved
regarding the fundamental conclusions to be drawn from the results of the external peer review,
subsequently the final report was compiled through an email discussion.

This report is composed of the following three chapters: “Chapter 1 Background,”“Chapter 2 Summary of Evaluations, and Proposals,” and “Chapter 3 In Closing.”

Meeting and its approval, the report was submitted by the Director General of National Institute for
Fusion Science to the President of the National Institutes of Natural Sciences. Subsequently, thereport will be submitted to the National Institutes of Natural Sciences Education and ResearchCouncil and Administrative Council, and after being approved the report is planned to be referencematerial for “Report of Administrative Achievements during the Business Year 2015” and “National
Institutes of Natural Sciences Annual Plan (2016).” This report will be made publicly available as a
printed text and as a homepage text.

Summary of Evaluations, and Proposals

Based upon the External Peer Review Committee’s discussions we summarized theimportant points of evaluation, and here offer several important proposals regarding theadvancement of the Numerical Simulation Reactor Research Project.

1. Summary of Evaluations[1] Development of research system and environment(1) Does the research system function appropriately in accomplishing the objectives of the
Numerical Simulation Reactor Research Project (NSRP)?
The structure of organic cooperation under which this Numerical Simulation Reactor
Research Project is being conducted together with the LHD Project, as well as the Fusion
Engineering Research Project is appropriate. And regarding the broad-ranging physical topics ofhelical plasma, research activities through various facilities are advancing together with flexibility
and motility as is seen in the eight-task group system and the linkages among task groups, which is
the research matrix of this project. And a research structure for developing and improving
world-leading simulation codes is being constructed. That this is functioning organically is highly
evaluated.
However, considered from the perspective of “Has the establishment of goals that eachgroup should respectively achieve and the evaluation of the levels of achievement been satisfactorily
implemented?”, strengthening of the system for checking the degree of advances regarding theoverall development goals, the securing of researchers who will undertake management that will
give birth to synergistic results from the links among research groups, and the balance of the numberof researchers, consideration of points arising from the project management likely will be necessary.
At the same time, it will be necessary for each research group to be aware of the goals of the project.
From the perspectives of cross-disciplinary linkages as well as the inter-university research
institute, as the warp and the woof of the project’s propulsion and academic development we hopethat this will support and develop research structures in which researchers contribute to both theadvancement and the academic development of the projects.

(2) Is the environment of the “Plasma Simulator” system and its related research developed
appropriately? Is the “Plasma Simulator” effectively utilized for collaboration research?

5For the introduction of our country’s third-ranked supercomputer, the preparation ofrelated research environments are advancing appropriately. Further, we can extremely highly
evaluate the new research results of exceptional quality that are emerging. We may greatly expect
research developments in the future. Accordingly, the way of advancing with current research, andthe preparation and management of the environment are appropriate. And that this is effectivelyfunctioning well can be evaluated. Further, not only the management of the supercomputer and its
usage, but also regarding the introduction of new machines, the parallelization of varieties of codeand the support of speeding-up that have been developed in this project, the holding of open lectures,various efforts for enhancing services on the National Institute for Fusion Science Webpage for theconvenience of users have occurred. This is highly evaluated.
Utilizing the environment that has been prepared under this project, more than fifty
projects have been effectively performed. And every year more than 15,000 individual jobs havebeen performed, and the average operation rate is 90%. Regarding the rate of utilization, too, this ishighly evaluated. Further, we evaluate the development of virtual reality-related tools that are aimed
toward the visualization of simulation results. In the future, in order to advance research results still
further, in addition to anticipating their efficient use, we anticipate disseminating the results to the
public.
On the other hand, in the operation of the numerical simulation reactor research project, in
addition to further clarifying expected indicators for measuring the degree of development by
utilizing the computational ability to be prepared, while constructing improvement plans thatcounterbalance targets step by step, please advance further. In the case of aiming for the best
conditions amid limited resources, with regard to the development of elements in whichdevelopment is advancing slowly, environment improvement which enhances calculation time andpriorities is necessary, and regarding the conditions of the progress of each group in the complete
plan is necessary.

[2] Research achievements
Does the NSRP produce high-level achievements in accordance with international standards
for the following research areas by promoting theory and computer simulation researchutilizing the Plasma Simulator?

(1) Construction of the Numerical Test Reactor for a helical fusion system
An important physical mechanism for determining plasma stability that is essential for fusion
plasma confinement, interaction with high energy particles, edge plasma behavior analysis and6interaction with the wall surface, verification of gyro-kinetic turbulence transport in devices such as
the LHD, and the further integration of analysis codes are being steadily developed regarding
individual topics. That the goals for the Numerical Simulation Reactor Research for the second
mid-term period have been achieved in general is evaluated. At the same time, that international
collaboration research is advancing and internationally high level research is being accomplished are
extremely highly evaluated. The training and the activities of young researchers too are highly
evaluated.
That the modularization of each variety of code that is considered in the application toward
experiment analysis, the development of code while being aware of its easy use, the comparison andthe verification of experimental results, and benchmarks through international collaboration research
activities will be thought to be all the more important in the future, we anticipate still further
progress.
On the other hand, the fundamental policy for the construction of the Numerical Test
Reactor does not seem to be clear. Considering both the perspective from plasma physics asrepresented in the next section and the perspective of the reactor core design, we would like to seethat the path toward the numerical test reactor construction aimed at by this project should be madeclearer through organically unifying further the numerous codes that have been developed. On thisoccasion, bringing the roadmap into view showing that the integration will be completed after
completion of development of all elements, as already one part seems to be beginning at present, theproject members should quickly plan the strengthening of the system and prepare research plans thatconsider integration of each developmental element at all times.

(2) Physics mechanisms of fusion plasmas and their theoretical systemization
From analysis that utilized various types of codes which have been developed, the Projectcontributes greatly to clarification of the structures of important physical phenomena from thereactor core plasma to the wall, including results that link to analyses of actual LHD experimental
results and to the FFHR design, the results of “Clarification of the Physical Structure of Fusion
Plasma” developed by each task group can be extremely highly evaluated. At the same time,
simulation calculations are contributing greatly to clarifying physical mechanisms with regard toresults gained from consistency with theoretical predictions and from experiments. Further, newdevelopments in theoretical systemization are seen, and that numerous research results bearing
impact are appearing is worthy of evaluation. Through this project, researchers are spurring on otherresearchers and active research is being undertaken and appearing in tangible forms. Positive
feedback is occurring, and the emergence of still further research results is anticipated.
While fundamental research parts that underlie this project are being appropriately
7supported, that the project’s contributions to plasma science are being greatly achieved is evaluatedhighly. In particular, that magnetic reconnection and the analysis of the Rayleigh-Taylor instability
are providing results that contribute to our understanding of the fundamental theory of plasma shouldbe specially noted.
In addition, that academic results are appearing not only as academic knowledge, but arealso gracing the covers of academic journals as images with impact utilizing visualizations ofdevices, can be evaluated for spreading this project’s presence in Japan and abroad. In the future one
anticipates further contributions through international journals.
On the other hand, regarding computer simulations, the development of numericalsimulation methods is important. And in the past, in view of the fact that from the field of fusion, too,
were proposed many new numerical simulation methods, from now, all the more, in addition topouring efforts into the field of numerical simulation methods, we anticipate the emergence of new
methods from the world of fusion.

[3] Promotion of cooperation and collaboration(1) Does the NSRP promote collaboration research as the center of excellence by integrating
the high capabilities of universities and institutes?
In the mathematical structure and the numerical calculation methods of simulation in theplasma and fusion fields are many points of similarity. This knowledge and experience is shared
among researchers, and the effort for the vitalization of research interaction is highly evaluated.
Further, it is evaluated that through theoretical collaboration research and Plasma Simulator
collaboration research the Project contributes to theory aimed at clarification of physicalmechanisms of fusion plasma at universities, and from the delivery of numerous results researchdevelopments appropriate to a Center of Excellence are advancing. Moreover, as is seen in the factthat integrated research is being undertaken by using transport codes developed at universities as abase, and turbulence transport codes are developed at the National Institute for Fusion Science, andhigh energy particle and MHD codes are being utilized for ITER and JT-60SA research, thatcooperation among universities and independent administrative agencies is steadily proceeding, too,is evaluated.
On the other hand, despite the fact that research is advancing, that the number ofcollaboration research projects is nearly constant raises the worry that the number of researchers
involved in collaboration research has settled. We anticipate efforts being made in the education ofparticipating researchers and in advertising their activities.
8(2) Does the NSRP contribute to the development of research in universities?
Does the NSRP function as a research hub for the dissemination of academic information toother fields?
Not limited to the field of fusion simulation, the Project is contributing to advancing
interaction among researchers in the broad basic sciences and to creating new academic fields, isdeveloping new simulation codes and undertaking analyses by establishing links between technicalcolleges and universities, and is contributing greatly to research development at technical colleges
and universities. This is highly evaluated.
Advances in understanding the various structural formations and dynamics inside asmall-scale dissipative plasma, such as two-fluid MHD simulation research and turbulencesimulation research which includes electron system dynamics and electromagnetic modes, areproceeding. That the Project is producing competitive research results with other fields and is
obtaining results spanning various fields seen in collaboration research within the National Institutesof Natural Sciences is highly praised.
On the other hand, it is necessary to heighten still further dissemination strength toward
broad areas that include other academic disciplines and industry. From the complication ofphenomena that accompanies the improvement of modeling integration and hierarchy, regarding theconstruction of the Numerical Test Reactor as warp and the fundamental research constructing theuniversality of theory as woof, it is desired that the Project makes effort in improving cooperationthat will strengthen competitive power in communicating with other fields, and together with this wewish to anticipate that the understanding of still more researchers and students will deepen, looking
toward the creation of new academic areas through academic activities and undertaking broader andstronger dissemination activities.

(3) Does the NSRP promote international cooperation through contributions to ITER, BA
activities, and other international collaborations?
In addition to contributions to BA activities, which are the core of the IFERC activities,
and contributions to the ITER project through participating in ITPA, through international
cooperation such as Japan-United States cooperation, which for many years has focused on JIFT,Japan-Europe, Japan-People’s Republic of China-Republic of Korea, and Japan-Republic of Korea,
the broad contributions to international cooperation are highly evaluated. Further, that the Director of
the Rokkasho Research Center concurrently serves as the head of IFERC, and that among theJapan-Europe implementation bodies smooth activities are being actively conducted are evaluated.
9

Because the expansion of international cooperation is contributing greatly to the promotionof this project, together with fulfilling the principal contributions to the LHD deuterium experimentresearch and to the helical-type fusion reactor research, we wish to see still further promotion ofinternational cooperation, including contributions to ITER and BA activities.

[4] Human resources development(1) Does the NSRP contribute to the development of human resources for the international
scientific workforce required for long-term fusion science through simulation research?
Every year graduate students enroll in Sokendai and receive education. The Projectcontributes to the development of human resources, and contributes broadly to the development
activities for students in the sciences and mathematics such as SSH activities. Further, that theeducation activities for graduate students through the summer school program for students in Japanand the winter school program for graduate students from other Asian countries are being undertaken
is evaluated. Further, in this project, numerous graduate students and post-doctoral students arebeing supported, and as a result they are contributing to the publication of academic articles andpresentations at international conferences. We highly evaluate that development of young
researchers is being undertaken appropriately.
On the other hand, regarding the development of graduate students and young researchers,
in observing the future importance of the simulation field, the quality of the students is sufficient but
their numbers are rather few. While the importance of simulation research in DEMO reactor design
will continue to grow, on the other hand there is worry that there will be few people. As a DEMO
reactor design, we anticipate clarification of its position with regard to the important simulation
fields, and efforts to organize the development of human resources for the promotion of simulation
research.
Moreover, in the petaflops-level simulation that may be developed, accompanying thedevelopment of the massively parallel computer, this will necessitate the use of high-levelspecialized knowledge. In the future, in order to achieve results in large-scale simulations for plasma
and fusion research that will be competitive with other fields, it is indispensable that young
researchers receive appropriate education and training, and we anticipate the organizational
response.

10[5] Future plans(1) Is the NSRP research plan for progressing toward the realization of the objectives
appropriate? Is the research plan suitable for the next decade?
Among many topics, there were many advances that should be seen in the utilization ofsimulations for effective tools in order to analyze and interpret the LHD experimental results. In thethird mid-term plan, the view that simulation will proceed more to joint-type is in an appropriate
direction, and further advances are anticipated.
On the other hand, the definition of the numerical test reactor is not clear. Further, it cannot
be said that the procedure for integration is clearly expressed. Examination of the current plan isnecessary. Regarding the Numerical Test Reactor, simulations with several analysis levels from theaccurate and large-scale simulation, to mid-scale simulation which will be utilized for theexperimental analysis, and to small-scale simulation which will be utilized in the reactor design.
Because of this it will be necessary to develop strategic simulation research that clarifies its object.
Regarding the supercomputer, which is indispensable for integration, in order to be able tocontribute to the further development of plasma and fusion research, the introduction of a still
higher-performance supercomputer will be actively promoted.

11

2. Proposals
In this current evaluation, resulting from discussions regarding the Numerical Simulation
Reactor Research Project, proposals regarding a future path forward are summarized below.

(1) Clarify more clearly the final goals of the entire project “Numerical Simulation Reactor
Research Project,” and have them in common in each research group, and strengthen the checksystem regarding the degree of advancement of a research group’s goals. In addition, it isnecessary to consider the management to produce the results due to synergistic effects fromthe links between research groups.

(2) While placing in view the roadmap which integration will complete finally, strengthening the
preparation and the system of the research plans that have always been aware of the
combination and integration of each development element should be quickly undertaken.

(3) Regarding the preparation of the Plasma Simulator and the related research environment, we
anticipate a preparation plan that inspects the condition of the progress of each group within
the overall plan and that follows the stage-by-stage achievement goals that take account of thecondition of the progress. In particular, regarding the supercomputer, which is indispensable
for integration, we hope into the future for the active promotion of the introduction of asupercomputer of still higher performance to contribute to further development of plasma andfusion research.

(4) Considering the project’s promotion as the warp and the academic development as the woof,
together with supporting and developing a research system in which relevant researchers
contribute to both and, in addition, promoting international contributions that include
collaboration research, we hope to advance further competitive strength that can be extended
to various other fields and to advance the creation of new academic research areas throughmulti-disciplinary activities.

(5) And also for maintaining simulation research activities important for development of thefusion reactor with high standards that will continue into the future, we anticipate undertaking
efforts together with universities and other organizations toward systemizing human resource
development that will enrich quality and quantity.

Chapter 3

In Closing

At the National Institute for Fusion Science, upon the beginning of the second mid-termgoals period from 2010, in order to strengthen still further the centripetal force as a Center of
Excellence in the plasma and fusion fields, the National Institute for Fusion Science composed
research projects in the three fields of LHD, numerical simulation reactor research, and nuclear
fusion engineering research. Aiming toward realization of the fusion reactor, the National Institutefor Fusion Science initiated research plans that will integrate these results. For that reason, in 2010
restructuring of the research organization, too, was undertaken. All research staff were organized into
one research department, a system that allowed each researcher to freely select participation in threeprojects was introduced, and links among the three projects, LHD, Numerical Simulation Reactor
Research, and Nuclear Fusion Engineering Research, were promoted. And regarding issues, theability to respond according to circumstances is anticipated.

At the National Institute for Fusion Science Advisory Committee, first, in 2011 the LHD
Project, in 2012 the Numerical Simulation Reactor Research Project, in 2013 the Nuclear Fusion
Engineering Research Project, and in 2014 the Deuterium Experiment Implementing Plan,
underwent external peer reviews, respectively. Then, in this current year, 2015, an external peer
review of the “Numerical Experiment Reactor Research Project” was undertaken. As members of theexternal peer review committee, there are 10 outside members of the Advisory Committee and three
foreign members. Further, five members from outside the National Institute for Fusion Science whoare specialist researchers and two foreign specialists were added, and these persons composed theexternal peer review committee, and they undertook their evaluation.

At the First External Peer Review Meeting and the Specialists Meeting held on October 21,
2015, there was discussion regarding how to advance with this year’s external peer review, and it
was decided to evaluate the points below.

[1] Preparation of the Research System and the Research Environment(1) In undertaking the Second Mid-term Plan and Mid-term Objectives, did the research system
function appropriately?
(2) Is preparation of the Plasma Simulator and the related research environment being advanced
appropriately? Further, is it being utilized effectively?

[2] Research Results
In advancing with theoretical simulation research that utilized the Plasma Simulator, for the two13

fields below listed in the second mid-term plan, are results of high international standards being
achieved?
(1) Construction of the Numerical Test Reactor(2) Clarification of the physical mechanisms of fusion plasma and its theoretical systemization[3] Promotion of Collaborative Use and Collaborative Research(1) Are the high-level research abilities at universities and other institutions being widelyconcentrated, and is collaborative research as a Center of Excellence advancing appropriately?
(2) Does the Project contribute to research development at universities, and contribute as an
academic hub that can disseminate to other academic fields?
(3) Through cooperation with ITER project, BA activities, and others, are contributions tointernational cooperation being undertaken?

[4] Development of Human Resources
Through simulation research, are there contributions to the development of human resources who
can be internationally active in supporting the long-term development of fusion research?

[5] Future Planning
Is the next research plan appropriate for future goals? In particular, does it view the mid-term and thelong-term prospects?

Subsequently, at the second External Peer Review Committee meeting and the Specialist
Meeting, which were held on November 28, 2015, there was a detailed explanation given that
followed the standpoint of evaluation and the points of evaluation, and a question and answer session
followed. Moreover, on January 20, 2016, the third External Peer Review Committee meeting and
the Specialist Meeting were held. The evaluation process and its coordination that followed thepoints of evaluation and topics determined by the External Peer Review Committee, including
further questions and answers with the National Institute for Fusion Science, were undertaken. As
the result, we achieved agreement in principle regarding the fundamental conclusions of the resultsof external review. Subsequently, resulting from this, the final report was compiled throughdiscussions held via electronic mail.

As results of this external review of the Numerical Simulation Reactor Research Project,regarding the review items above, the conclusion of “highly evaluated in general” can be stated. In
particular, regarding the Plasma Simulator, we can extremely highly evaluate the point that ourcountry’s third-ranked supercomputer has been introduced and is contributing widely to the14simulation research of the fusion plasma community. Further, the high-level research abilities ofuniversities have been widely concentrated, and together with actively promoting collaboration
research as a Center of Excellence and the contributions to the development of human resources who
can actively participate internationally in the fusion field is highly evaluated. Moreover, regarding,too, the high-level simulation research aimed at the construction of the Numerical Test Reactor andthe clarification of physical mechanisms of fusion plasma, excellent results at the global level areappearing in large numbers, and this is highly evaluated. And regarding results that may be
disseminated to other fields, and active participation and contributions to ITER and BA activities,
too, these are highly evaluated. In the future, we hope there will be further academic disseminationand still further promotion of international cooperation with ITER. Regarding the Numerical
Simulation Reactor Research Project, the world’s leading research system that develops andorganizes calculation codes is highly evaluated. However, from evaluation of the setting of goals andthe levels of achievement, and, moreover, from management that can give birth to synergistic results
based upon still further linkages among research groups, still further efforts are requested. Yet, forthe further development, too, of plasma and fusion research, we anticipate continued effort aiming
toward the introduction of a supercomputer of still higher performance.

Finally, we have summarized proposals regarding the path forward from now for the
Numerical Simulation Reactor Research Project.

(1) Together with expressing more clearly the final goals of the “Numerical Simulation Reactor
Research Project,” and together with joint cooperation among each of the research groups,
strengthening the system for checking the degree of completion with regard to the goals of theresearch groups. At the same time, it is necessary to consider a management that will givebirth synergistic results through linkages among research groups.

(2) While keeping in view the roadmap that will complete integration, the strengthening of the
preparation and the system of the research plan that is already aware of the combinative
integration of each development element must be promptly undertaken.

(3) Regarding the preparation of the Plasma Simulator and the related research environments, we
anticipate inspecting the conditions of each group for advancing the overall plan, and weanticipate that the preparatory planning that corresponds to the step-by-step achievement goals
that take account of the conditions.
In particular, regarding the supercomputer, which is indispensable for integration, we
anticipate active promotion in the future of the introduction of a still more powerful15high-performance supercomputer for contribution to the further development of plasma andnuclear fusion research.

(4) As the warp and the woof for the project’s promotion and academic development, supportingand developing research systems to which related researchers will contribute to both. In
addition, we hope to advance the creation of new academic areas through multi-disciplinary
activities that enhance competitive power that can extend to other fields.

(5) To maintain high standards that will continue into the future, and in order, too, to maintain
important simulation research activities for the development of the fusion reactor, we
anticipate effective planning for both quality and quantity in dealing organizationally in
preparing human resources together with universities.

Linear branch of electron diamagnetic rotation of idealinterchange mode is obtained[T. Nicolas, et al., Plasma Fus. Res. 2015, submitted to Nuclear Fusion 2015]• Diamagnetic rotation of interchange modes is studied with both 3D MIPS
simulations and eigenvalue analyses based on 3-field reduced MHD model.

• Effects of heat conductivity and viscosity on the mode rotation are studied.
Dominance ofmode rotatingin the electron
direction• Some MIPS results with viscosity and heat conductivity show rotation in theelectron diamagnetic direction that is observed in LHD experiments.
• 3-Field analysis shows that sufficient large heat conductivity and viscosity
make the branch with the electron diamagnetic rotation dominant.

33/154

Rotation velocity of resistive interchange modes in
LHD experiments is reproduced by simulation[M. Sato, et al., 11th APPTC 2014 (oral)]• In LHD experiments, it is observed that interchange modes rotate with theelectron fluid velocity (electron diamagnetic velocity + ExB flow velocity). skip
• In this study, the propagation velocity of interchange modes is investigatedby nonlinear simulation based on four-field model in slab plasmas.

Island width / ion Lamor radius• In the linear phase, the propagation velocity of modes is about 60% of theelectron fluid velocity. In the nonlinear phase, however, magnetic islands areformed and the propagation velocity becomes close to the electron fluid
velocity as the saturated island width increases.

• A magnetosonic shock wave can trap electrons andaccelerate them to ultrarelativistic energies. Theseelectrons excite multi-dimensional fluctuations,which significantly influence electron motions.

ionreflected ionselectronl t• Effects of trapped electrons on ion motionsin an oblique shock wave have been
investigated with particle simulations.
• It is found that the number of accelerated
ions via reflection from the shock front isincreased because of the multi-dimensional
fluctuations excited by the trapped electrons.

gyrokinetic
theory [S[Sugama,
466 (2000): cited over 100 times (Google Scholar)] presents the variational skip
principle, from which all governing equations for gyrocenter distributionfunctions and turbulent electromagnetic fields are derived.
• These gyrokinetic equations exactly satisfy phase-space volume invarianceand energy conservation for collisionless systems under stationary
background magnetic fields.
• Extensions of gyrokinetic field theory are made to include effects of collisions[Sugama et al., PoP 22, 082306 (2015)] and of time-dependent backgroundmagnetic fields [Sugama et al., PoP 21, 012515 (2014)].
• Extended gyrokinetic equations are shown to keep conservation properties
and they can properly describe all processes of classical, neoclassical, andturbulent transport of particles, energy, and toroidal angular momentum in
confinement time scale.
• These results are useful for future long-time global gyrokinetic simulations
and they are presented in two invited talks for international conferences(2014, 2015).

Tasks of PL• To coordinate activities of EU and JA Implementing Agencies (IAs).
• To prepare input documents of the IFERC Project Committee (PC) for reporting activities and getting
recommendation of the PC to invite the Steering Committee (SC) to approve proposals. (In spring, themain input documents are the annual report of the last calendar year and updated project plan. In
autumn, those are work program of the next calendar year and summary report. Update of Value
Estimates and Allocation of Contributions of the Parties is proposed just in case.)• To hold and attend various managerial and technical coordination meetings (TCMs). (ex: Extended
Project Team Meeting almost every two weeks with Fusion for Energy (F4E)).
• To assist preparation and implementation of the Procurement Arrangements.
Other recent activities as PL:• To organize CSC review meetings with spring PCs, REC-TCMs twice per year from 2013
• To organize Joint TCMs between DEMO Design Activity and DEMO R&D Activity from 2013
• To organize DEMO review meetings with autumn PCs from 2014
• To create and analyze the database of the simulation projects by using CSC [see below]
