3. Fast Breeder Reactor cycle R&D
Main objectives of FBR cycle are effective utilization of uranium resources, decreasing of
environmental burden from high-level radioactive waste by recycling MA in the fuel, and strengthening
the proliferation resistance by mixing MA in the recycled fuel. Prototype reactor “Monju” restarted
operation in May 2010. In 2005, the government decided the main concepts of FBR R&D: sodium cooled
and MOX fueled FBR and advanced wet process for reprocessing and compact type pellet fuel
manufacturing. From FY 2007, Fas t Reactor Cycle Technology Development Project(FaCT project)
