Japan’s basic nuclear policy is to reprocess spent fuel and to effectively use the recovered plutonium and
uranium. MOX fuel utilization in LWRs is promoted in 16-18 reactors by FY2015. Commercial operation
of Rokkasho Reprocessing Plant is planned to start in 2012. Prototype reactor “Monju” restarted operation
in May 2010. From FY 2007, Fast Reactor Cycle Technology Development Project (FaCT project) started
which focuses more toward the commercialization stage FBR cycle. Basic scenario of Japan’s R&D aims
for realization of demonstration FBR by around 2025 and introducing commercial FBRs before 2050.
Smooth transition from LWR fuel cycle to FBR one is an important point. For nuclear fuel cycle which
requires long term R&D, human resources development and keeping is vitally important.
