Japan's strategy for structural material development for DEMO reactors is the staged approach, focusing on the development of reduced activation ferritic/martensitic (RAFM) steel F82H (Fe-8Cr-2W-V, Ta), which is the main optional material for in-core structures [1]. Full qualification of RAFM steel F82H to be used as fusion in-vessel structural materials in a “real” fusion environment of...
The MINERVA project is currently designing/constructing a 100MeV, 4mA proton, super-conducting linac at the Belgian nuclear research center SCK CEN.
Once operational, it will be used to demonstrate compliance to the extraordinarily high operational reliability requirements. These are imposed by its expected future role as the first part of the MYRRHA Accelerator Driven System (ADS), where a...
The fusion neutron source A-FNS, whose engineering design is under consideration by QST of Japan, is planned to implement various experiments for fusion reactor candidate materials. A-FNS is a fusion neutron source using d-Li reaction as in IFMIF-DONES, and its neutron generation intensity is comparable.
In addition to irradiation test of reduced activation ferritic steel (F82H) in the...
The mission of the IFMIF-DONES facility is to provide irradiation data for the construction of a DEMO fusion power plant. It is a deuterium-lithium (d+Li) neutron source driven by a deuteron accelerator (40 MeV and 125 mA) striking at the liquid Li target and producing neutrons through stripping reactions. The neutrons provide high damage doses on material samples located in the High Flux Test...
As a complementary purpose of materials irradiation, a collimated neutron beam from the IFMIF-DONES Test Cell (TC) will be supplied to Complementary Experiments (CER) for the users to conduct a variety of neutronics experiments. This work includes the results of the neutronic modeling and analyses of the neutron tube and the Neutron Beam (NB) shutter with the open and closed design...
The conceptual design of neutron beam shutter and neutron beam channel has been proposed as one of the subtasks of the Test Systems task in the DONES project partially funded by the Horizon Europe Program. The neutron beam channel and the shutter enable the neutrons produced in the lithium target in the Test Cell, which is the heart of the IFMIF-DONES facility, to reach the Facility for...
In the recent years, various neutron research reactors have closed, reducing the access of scientists to neutron facilities to perform neutron scattering experiments in Europe. The Institut Laue-Langevin, the world leading reactor of its kind, key for the neutron scattering community is also expected to close by the end of this decade. The European Spallation Source (ESS) should start...
A series of Complementary Experiments in the IFMIF-DONES facility that could be of interest for the Scientific Community were proposed within the DONES-PREP FP8 EC project. Such experiments would profit from two eventual experimental areas used for this purpose: (i) the room R160, adjacent to the Test Cell and connected with it by a duct through which neutrons would be extracted and...
Steps to be made to establish a users community and a dedicated system for the users' communication and access to the facility and approach to make preliminary decisions on wich ones of the different proposals should be included in the presently going-on engineering design
