In this paper, the terminologies and ideas of SCM was introduced into the scenario study to give a fresh perspective for considering LWR cycle to FR cycle transition strategies in Japan. Then, an analytical tool (SCM tool) which has been developed by the authors is used to survey Japanese nuclear energy system in transition with the SCM terminologies and viewpoints. As the result of the investigation on the boundary location of "Push type" and "Pull type", the consideration of "Pull-type" operation as well as "Push-type" by SCM tool can expand the scope of future transition strategy construction from LWR cycle to FR cycle.

Comprehensive dynamic analyses of the typical Fast Reactor (FR) deployment scenarios with JSFR and related fuel cycle facilities developed in "FaCT: Fast Reactor Cycle Technology Development" project were conducted. In this study, combinations of analysis codes, which consist of two energy economic models (computable general equilibrium (CGE) model and energy system model) and dynamic analysis model for nuclear energy supply chain, were used for the dynamic analyses. As a result of the analysis, FR cycle should be deployed from 2040 to 2050 to curb the cumulative uranium resources consumption within the conventional uranium resources reported in Uranium 2009 by the OECD/NEA and the IAEA.

This paper treated the conceptual sides of the methodology for evaluating total nuclear energy systems in FaCT (Fast Reactor Cycle Technology Development) project of Japan Atomic Energy Agency and the efforts to develop the database system in the field. After the introduction of FaCT project and the performance targets as the basis of the total system evaluation, the way of designing the data formats and contents suitable for the nuclear energy system strategy evaluation and the evaluation methodologies were discussed. The framework of object-oriented analysis and enterprise architecture was tentatively used to streamline the nuclear materials, facilities, and socio-environmental data. Moreover, the methodologies were classified and work-flows of the evaluation were visualized. Based on those activities, the database concept was established to manage the data and methodologies for quality management and/or knowledge management.

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.

An analysis tool to assess the characteristics of transition period from current LWR cycle to FBR cycle has been developed with consideration of nuclear supply chain. This study surveyed the effect of difference of FRs' breeding ratios (1.1 and 1.2) in the early stages of deploymnet on the economics from the . The Preliminary analysis showed there was not large discrepancy in economics between the FR cycles with different breeding ratios.

Synthetic evaluation methodologies and the database to manage the data and methodologies have been developed based on the data for synthetic evaluation and the modeling of the total nuclear energy system. The database will be used to establish standard data and methodologies for synthetic evaluation for the purpose of quality management and/or knowledge management of the synthetic evaluation.

FBR core concepts are proposed to improve inherent proliferation resistance features for the blanket regions which can generate high Puf contents. This study presents the evaluation results for the scenarios to deploy FBRs with the improved inherent proliferation resistance core and argues the feasibility from the viewpoint of mass-balace, influence on economics, and non-proliferation features.

When the nuclear energy capacity of Japan is reduced, the characteristics of nuclear energy systems are assessed based on the nuclear fuel cycle schemes with the suppositions of long-term nuclear energy scenarios including after 2030. The deployment of fast reactors and recycling of spent fuels have enough merits from the viewpoints of spent fuel management and radioactive waste management according to the assessment in this study.
