Call for proposals for BA simulation projects in JFRS-1_2023_v1.0

Call for proposals for BA simulation projects in JFRS-1(2023/4/1 to 2024/3/31)
Deadline for answers: Friday, 10th February 2023
1. Preface
The Broader Approach (BA) activities entered the BA Phase II in April 2020 buildingon the successful results of the BA Phase I (from June 2007 to March 2020). The
objectives of the International Fusion Energy Research Centre (IFERC) in BA Phase II areto support ITER, JT-60SA and IFMIF/EVEDA and to consolidate the know-how for thedevelopment of future fusion reactors (DEMO). In line with the objectives, F4E together
with EUROfusion and QST continuously promote simulations in the Computational
Simulation Centre (CSC), as part of the IFERC project activities (IFERC-CSC).
For this purpose, the high performance computer resource JFRS-1 in Rokkasho isprovided by QST as a Japanese host contribution to BA Phase II. Therefore, this resourceis available to implement EU and Japan projects and EU-JA joint projects in FY 2023
(from April 2023 to March 2024) as well as in FY 2022. Resources are reserved forprojects targeting priority areas relevant to the objectives of the IFERC project, and theprojects must address issues relevant to fusion development programmes such as ITER,
JT-60SA, DEMO or IFMIF/EVEDA.
2. Scope of simulation projects
In order to promote the HPC simulation projects smoothly, with this call for
proposals, we would like to invite scientists and engineers to propose project(s). Projects
must address issues relevant to• ITER,• JT-60SA,• DEMO,• IFMIF/EVEDA.
The issues in primary categories will be as follows:• Divertor physics:(improved models, detached conditions, poloidal asymmetry, plasma surface
interactions, heat load, etc.),•Edge physics:

(improved confinement, L-H transition, Edge Localised Modes, 3D effects
such as Resonant Magnetic Perturbations, etc.),
Disruption:(overall modelling, effects of runaway electrons and mitigation systems, etc.),
Plasma turbulence and related transport processes:(core or edge turbulence, transport barrier, etc.),
Fast Particle physics:(influence of Alfvén Eigenmodes on Fast Particle confinement and/or burning
plasma, etc.),
Integrated modelling of fusion plasmas:(overall modelling, application to burning plasma, etc.),
Heating and current drive:(NBI, ECH, ICRF, etc.)
Reactor materials:(irradiation effects on reactor materials, structural materials [ReducedActivation Ferritic Martensitic steels], functional materials [neutron multiplier,tritium breeder], divertor materials [W], etc.)
Reactor technology:(nuclear analysis, neutronics, etc.).

3. Specification of the available computer system
The computer available in JA is Japan Fusion Reactor Simulator 1 (JFRS-1) in the
Rokkasho Fusion Institute of QST. JFRS-1 is the Cray XC50 supercomputer with 1,370
conventional CPU nodes, and each compute node has 2 Intel Xeon Gold 6148
(2.4GHz/20C) processors and 192GB of memory. The peak performance of JFRS-1 is
4.2 PFlops.
The total amount of available node hours for this call in JFRS-1 is 9,000,900 nodehours. Please note that the above-mentioned total amount of available node hours will beshared among the selected proposals.
4. Eligibility for proponents and participants in projects
The Principal Investigator, and co-Principal Investigator if any, of each project musthave a contractual link with some recognised fusion research organisation in EU or JA,and be empowered in this organisation to propose this kind of project. In the case ofscientists not belonging to such organisations, they can participate in the project only as

3Call for proposals for BA simulation projects in JFRS-1_2023_v1.0

collaborators and their participation in the project must be covered by a formalagreement. Also, the Principal Investigator, and co-Principal Investigator if any, will
ensure that the total amount of node-hours allocated to all the scientists belonging to neither
EU nor JA research organizations in a project is limited to a maximum of 50% of the nodehours allocated to the project. The acceptance of recognised fusion research organisations
will be under the responsibility of the Implementing Agencies.
5. Proposal and selection
The proposal should detail the objectives of the project, the relationship of theproject to issues of ITER, JT-60SA, DEMO and IFMIF/EVEDA, and the required
resources following the attached “Application form for BA sim. in JFRS-1_2023.docx”.
In the proposal, it must be described in detail the justification/rationale for the use of
the resources requested, by including the information in terms of expected number ofruns, number of nodes used, and elapsed time per run and the relationship to the scientificobjectives; without proper justification/rationale for the use of resources the project will
be rejected.
Proposals will be selected according to a peer review process defined by the Joint
Allocation Committee; only proposals, which are technically fit for the JFRS-1, will bekept while the final selection will be made according to the scientific and technicalmerit of the proposals taking into account the following criteria:(1) Relevance to issues of fusion development programmes: ITER, JT-60SA,
DEMO and IFMIF/EVEDA, and clearness of research plan (40%, threshold: 2),(2) Quantitative justification of the requested computer resources and relationship to
the objectives (20%, threshold: 2),(3) Scientific excellence including innovation potential (20%, threshold: 2),(4) EU/JA collaborative aspects (20%),
where proposals with one or more evaluations below the threshold of 2 (the range ofevaluated values is from 0 to 5) in categories (1), (2) and (3) will fail. Note that thecriterion (4) has no threshold, and a well evaluated project contains a Principal
Investigator from one side and a co-Principal Investigator from the other side, and has
clearly defined benefits of a EU/JA joint collaboration together with the roles of both EU
and JA researchers.
Remark: for proposals using data from experimental facilities (including the usageof data from ITER, JT-60SA, DEMO and IFMIF/EVEDA), a collaboration agreement
should be concluded separately. In such cases, please contact the authority managing the4

data.
6. Presentation and publication of obtained results
The participants must agree to acknowledge EUROfusion and QST when theresults of the projects are presented and published. A suitable acknowledgement is asfollows: “This work was carried out (partially) using supercomputer resources, JFRS-1
provided under the EU-JA Broader Approach collaboration in the Computational
Simulation Centre of International Fusion Energy Research Centre (IFERC-CSC).”
7. User Access and Export control
Japan and European Union countries are parties to the Wassenaar Arrangement,
which ensures an Export Control with respect to high level, possible dual-use technology
components, including supercomputer technical information, knowledge, set-up, anduser access. For the purpose of obtaining user access, all prospective users will have toprovide personal information such as nationality and the place of abode, which will be
used only for this purpose.
This process is completely independent of the selection process for research projects
by the Joint Allocation Committee. This process will be done separately and in parallelwith the selection process, enabling the checking to be followed by F4E and QST thatwill have to be completed before account opening after the project is granted. The JA
management staff will notify EU applicants for using the JFRS-1 of details of this process
through e-mail after receiving the application forms.
8. Contact points
The proposals should arrive at the Joint Allocation Committee (alloccom@iferc.org), by Friday, 10th, February 2023. Adopted projects will beimplemented from 1st April 2023 to 31st March 2024. Questions on the call for proposals
should be sent to the Joint Allocation Committee (alloc-com@iferc.org).
After completion of the project, a short written report (i.e. 1-2 pages) presenting themain results is required and shall be sent to the Joint Allocation Committee (alloccom@iferc.org) by the end of May 2024. If applicable, this report will be taken into
account when assessing a continuation of the future simulation projects in the BAframework.
