Design study on large scale fast breeder reactor; 1,000 MWe-size reference plant

not registered

Based on the results of "Study on Main Design Parameters of Large Scale Fast Breeder Reactor" performed up to the fiscal year before last, an overall design study on a 1000 MWe-size FBR plant was made in the last fiscal year up to the level where cost evaluation could be done roughly. The design study was done on the assumption that the construction of the target plant be started within 1990's. The goal of this study was to design an FBR plant which was feasible to achieve a construction cost of 1.01.1 (formerly 1.11.2) times as much as that of light water reactor plant at the same age, and was also feasible to achieve an average burnup of 130,000MWd/t for discharged core fuel sub-assemblies. In this design study, however, the goals could not be achieved. It was made clear that further studies based on the results of the present study were necessary on main design parameters, and that more efforts were required for the fiscal year of 1989. As the result of this design study, problems were pointed out which should be taken into account in future R&D programs. And also, it was realized that the design study needs to be proceeded in cooperation with R&D activities.
