Scenario study on fast reactor cycle deployment

Ono, Kiyoshi ; Shiotani, Hiroki; Hirao, Kazunori

JNC started the feasibility study on commercialized Fast Reactor (FR) cycle system in 1999 and is estimating several promising FR cycle concepts. This report summarizes the analysis about the necessity of FR cycle deployment in Japan and in the world from a long-term viewpoint, by comparing "FR scenari" with "LWR once-through scenario" and "Pu recycling in LWR scenario". The necessity of FR cycle deployment in Japan and in the world was confirmed from viewpoints of effective utilization of uranium resource and reduction of environmental impact.
