Manjusri - Monju

Japanese: 文殊 - モンジュ

A fast breeder reactor of the Japan Atomic Energy Agency located at the northern tip of the Tsuruga Peninsula in Fukui Prefecture. It is a domestically developed prototype fast breeder reactor for power generation, which breeds plutonium fuel with high-speed neutrons and cools it with sodium. It was built for the purpose of demonstrating its reliability as a power plant and establishing sodium handling technology. It was completed in May 1991, achieved its first criticality in April 1994, and began generating electricity in August of the following year, but a sodium leak accident occurred in December and operation was halted. Test runs were resumed in May 2010, but a device fell inside the reactor in August, and operation was halted again. In December 2016, the decision was made to decommission the reactor. The name comes from Manjusri Bodhisattva. The official name is Prototype Fast Breeder Reactor Monju. →Fugen →Nuclear power plant [Additional information]

福井県の敦賀半島北端部にある日本原子力研究開発機構の高速増殖炉。高速の中性子によって燃料のプルトニウムを増殖し、ナトリウムで冷却する、国産の発電用高速増殖原型炉。発電プラントとしての信頼性の実証と、ナトリウム取り扱い技術の確立を目的として建設された。平成3年（1991）5月に完成し、平成6年（1994）4月に初臨界を達成、翌年8月から発電を開始したが、12月にナトリウム漏洩事故が発生し運転停止。平成22年（2010）5月に試運転を再開したが、8月に炉内で装置落下事故が発生し、再び運転停止。平成28年（2016）12月、廃炉が決定した。名称は文殊菩薩に由来。正式名称は高速増殖原型炉もんじゅ。→ふげん →原子力発電所［補説］
