Conceptual design of DEMO blanket materials test modules for A-FNS

Abstract

• A-FNS is a fusion-like neutron source for irradiation of fusion reactor materials. • We established conceptual designs of 3 test modules for DEMO blanket materials. • 1-BFMTM: Irradiation data for blanket functional materials are obtained. • 2-TRTM: In-situ tritium recovery properties for the materials are evaluated. • 3-ACPM: ACPs are evaluated under the fusion-like neutron irradiation. A conceptual design of A dvanced F usion N eutron S ource, A-FNS, has been conducted to achieve early realization of fusion-like neutron irradiation test for fusion reactor materials in Japan. A-FNS provides eight test modules to obtain irradiation data for fusion reactor materials. Conceptual design activities on Blanket Functional Materials Test Module (BFMTM), Tritium Release Test Module (TRTM) and Activated Corrosion Products Module (ACPM) were described among the A-FNS test modules. Also, basic concepts of the sub-system cells for the TRTM and the ACPM were also discussed.
