This report presents the outline of the development and the results of characteristic evaluation on the candidate Fast Reactor (FR) cycle system concepts, scenario study on FR cycle deployment and cost-benefit analysis on the candidate FR cycle system concepts in the interim evaluation (FY2001 through FY2003) of the second phase of the Japanese "Feasibility Study on Commercialization of Fast Breeder Reactor Cycle System (FS)".

This report is intended to explain the outline of the scenario studies on FBR (Fast Breeder Reactor) cycle introduction. Recently, people value the reduction of environmental impact in addition to the recycle of energy resources and the energy security in these scenario studies. This report summarizes the analysis about the necessity of plutonium recycling in LWR (Light Water Reactor) from short-term view and about the necessity of FBR cycle introduction from a long-term view in Japan, by comparing "FBR scenario" with "LWR once-through scenario" and "Pu recycle in LWR scenario", from the viewpoints of cumulative uranium demand, spent fuel storage, radioactive waste arising, etc. It becomes clear that the plutonium recycling in LWR has a good effect on the reduction of spent fuel storage and the cumulative natural uranium demand before FBR cycle introduction, from short-term view (20 - 30 years). On the other hand, this analysis also shows that there is much effect of FBR deployment not only on saving amount of uranium use and energy security but also on reduction of high-level radioactive waste (spent fuels and vitrified waste) and minor actinide arising, from long-term view (100 - 200 years).

Methodologies for the dynamic analysis of nuclear energy system from current LWR cycle to FR cycle which will replace the LWR cycle system are developed in the "Feasibility Study on Commercialized Fast Raector cycle systems". The role and perspectives of the dynamic analysis are shown, and status and tentative results of the developmnent of the environmental burden reduction evaluation methodology are reported.
