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 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 research and development (R&D) in the FY 2001 on cost-benefit analysis of FR (Fast Reactor) cycle system concepts. The work was conducted as a part of the JNC's "Feasibility Study on Commercialized Fast Reactor Cycle Systems (the F/S)". In the FY 2001, the work conducted in the JNC was summed up as the followings: (1)Conceptual study on cost-benefit analysis for FR cycle R&D (2)Refinement on the evaluation procedure and improvement over operation efficiency (3)Cost-benefit analysis of the reference FR cycle and sensitivity analysis with the revised system (4)Cost-benefit analyses of R&Ds for various FR cycle candidate concepts including FR cycle concepts studied in the F/S phase 1 The work made it possible to evaluate the cost effectiveness of various FR cycle systems efficiently. The cost-benefit analysis, which is often used for the policy evaluation, is considered to be applicable to FR cycle system concepts in the F/S.

Some studies about the relation between burn-up and economics in the FR cycle have been performed until now. The results of these studies indicate that the core fuel assemblies with average burn-up of 150
200GWd/t is proper for target value from the economic viewpoint. The phase-I of JNC's "Feasibility Studies on Commercialized Fast Reactor Cycle System (the F/S)" started from 1999. In the F/S study, reactor construction cost, reprocessing cost and fabrication cost of FR cycle were revised iargely and importance of improvement of the average burn-up for whole fuel assemblies including blanket fuels was confirmed. Accordingly, based on the newest FR plant and core designs in the F/S study, the influence of the fuel burn-up on the generation cost was examined on the assumption that core diameter, CDF(Cumulative Damage Fraction) condition and so on are constant. The results may be summarized as follows. (1)As for the constant breeding ratio case (about l.1), the generation cost becomes the minimum at around 150GWd/t as average burn-up for core fuel assemblies (or at around 90GWd/t of average burn-up for whole fuel assemblies). It is caused by both effects of decrease of fuel mass flow, and increase of fuel cycle unit cost and decrease of load factor, as fuel burn-up rises. (2)When the breeding ratio increases (addition of axial blanket fuels), the generation cost rises because average burn-up for the whole fuel assemblies decreases.

Accompanying with the progress of the "Feasibility study on FBR cycle system; FS" , various kinds of technical information, facility design parameters, and related data will be obtained and they should be stored in data bases and be used as fundamental data for the FS. So the several data bases are going to be set up at each section and controlled by the management system through a local area network. Among above data bases, a prototype of FBR cycle data base that will record data for FBR scenario study and synthetic assessment is to be completed in. Phase l by fiscal year 2000, so the data base system concept has been examined in the current fiscal year, 1999. As the results of the system concept examination, two types of prototypes have been selected, one is to be set up as the data table containing digital data that are extracted from technical papers, another is as image data of papers with index information. Referring to examples of data bases in other companies, it was kept in mind to use a package software for general purpose and to utilize data existing now.

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.

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.
