Beryllium intermetallic compounds (beryllides) are the most promising advanced neutron multipliers. Development of the advanced neutron multipliers has been started between Japan and the EU in the DEMO R&D of the International Fusion Energy Research Centre (IFERC) project as a part of the Broader Approach activities. In Japan, beryllides fabrication R&D has been carried out in the DEMO R&D building at IFERC, Rokkasho. To fabricate the prototypic beryllide pebbles using the plasma-sintered beryllide rod, the rotating electrode method (REM) was selected because the experience base for its use is broad for not only Be pebbles but also metallic pebbles in industry in general. The result of beryllide granulation revealed that the prototypic beryllide pebbles with 1 mm in average diameter were successfully fabricated. In this study, the recent progress on R&D of beryllides as the advanced neutron multipliers in Japan will be presented., ベリリウム技術に関する国際会議(BeWS-13)}, title = {Overview of beryllide R&D as advanced neutron multiplier in Japan}, year = {2017} }
