Chapter 5, Transmutation system, 5.1 Transmutation system by fast reactor, 5.1.2 Experience in experimental reactor and prototype reactor and future research plan, 5.1.2(2) Prototype fast breeder reactor Monju

Kitano, Akihiro 

Prototype fast breeder reactor Monju has restarted in May 2010 after the long shutdown since the sodium leak accident. Before the restart the safety authority has examined the influence of the long shutdown, such as the characteristics of Am accumulated in MOX fuel. The integral data of the core with about 1.5% was acquired in the core confirmation test conducted in 2010 and the newest analysis method shows the enough accuracy. The irradiation test for the MA transmutation is planned, called GACID project by Japan, France and United States. The research of MA transmutation is one of the most important issues in Monju research plan included in the basic research plan decided by the cabinet council. It is expected that Monju would be utilized to demonstrate MA transmutation in the fast reactor.
