Recent progress of functional materials in fusion reactor field

In parallel to the ITER program, Broader Approach (BA) activities are being implemented by the EU and Japan, aiming at early realization of the fusion energy. Beryllium intermetallic compound (beryllide) such as Be12Ti, Be12V, etc. are candidates of the advanced neutron multipliers because beryllide has good potential under higher temperature more than Be. Based on the common interests of the EU and Japan in DEMO, R&D on beryllide are carried out through the DEMO R&D of the International Fusion Energy Research Centre (IFERC) project as a part of the BA activities. This activity has the objective of development of granulation technique of beryllide and its characterization. In this workshop, recent progress of R&D on advanced neutron multipliers as functional materials in fusion reactor will be reported.
