「高速増殖大型炉の設計主要目に関する研究」の成果を踏まえ、100万kWeクラスの大型高速増殖炉プラント全般にわたる設計研究を実施し、概略コストを評価できる段階に達した。100万kWe高速増殖炉の主目標を、1990年代に着工可能な技術レベルを想定し、建設費1.01.1(軽水炉比)、燃料燃焼度130,000MWd/Tとして設計研究を行ったが、本設計研究では、最終目標を達成できなかった。1989年度は、本設計研究の成果をもとに、さらに主要要素研究を実施し、上記目標を達成すべく努力する必要がある。また本設計研究から、研究開発計画に反映すべき項目が明確になり、R&D部門と連携して設計を進めていく必要がある。

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.
