For more accurately evaluation of the damage caused in the blanket structural materials in the nuclear fusion reactor and to verify their soundness during the service, under irradiation by the fusion neutron at a level that the ratio (He/dpa) of the helium production rate and displacement rate becomes close to 10, it is necessary to verify the material characteristics change due to the interaction between the defect created and the helium generation by various material tests. Therefore, verification using a high intensity neutron source with neutron spectrum simulating the fusion reactor like IFMIF is essential. In this chapter, based on the development technologies by IFMIF/EVEDA, a project for the construction of Advanced Fusion Neutron Source (A-FNS) facility planned by QST with proposals for its usage for various purposes is introduced.
