今年日本计划有三个反应堆和四个临界装置投入运转。东海村原子能研究所(茨城县)建造的热功率10000瓩的JRR-111反应堆即将完工。反应堆以天然铀作燃料,重水作减速剂。这是第一个日本自己制造的反应堆。装入的第一批燃料用进口的天然铀,以后计划用日本铀矿石所生产的铀。预计今年内,热功率30—100瓩、从浓缩铀作燃 This year Japan plans to have three reactors and four critical facilities in operation. The JRR-111 reactor, which is built at Tokai-mura Institute of Atomic Energy (Ibaraki Prefecture) and has a thermal power of 10,000 瓩, is nearing completion. The reactor uses natural uranium as a fuel and heavy water as a moderator. This is the first Japanese-made reactor. The first fuel to be imported was natural uranium imported and later planned to be produced from uranium ore from Japan. Expected this year, the thermal power of 30-100 瓩, from uranium enrichment for burning
