 note = {DEMO reactors require advanced neutron multipliers that have higher stability at high temperature. 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.
The Beryllium (Be) Handling Room has been installed in the DEMO R&D building. In this facility, synthesis, treatment, machining and characterizations of beryllides and its pebbles are being performed. Beryllium and its alloys (> 3 wt.% Be) are defined as controlled chemical substances in Japan. Therefore, equipment for safely handling beryllium is required; furthermore, regulatory authorities need to be notified of its use. The maximum concentration of beryllium was limited to < 0.001 mg/m3, the beryllium content in the beryllium handling area was monitored twice a year, and the controlled air velocity of the hoods that handled beryllium was maintained at 1 m/s according to the regulations., ベリリウム技術に関する国際会議(BeWS-13)},
