FBRサイクル実用化戦略調査研究の一環として、ナトリウム冷却炉、鉛ビスマス冷却炉、ヘリウムガス冷却炉、水冷却炉の各候補概念について、開発目標に照らした技術評価を行った。また、各候補概念について、実用化のために必要となる研究開発課題をまとめ、その概要をロードマップとして示した。

This paper describes the summary of an interim report of phase II of the Feasibility Study on Commercialized FR Cycle Systems, related to reactor systems. Promising plant concepts (sodium-, lead-bismuth-, helium-, and water-cooled fast reactor) and reactor core concepts are presented. These concepts are quantitatively evaluated from the viewpoint of the suitability to the development targets, such as economic competitiveness, efficient utilization of resources and reduction of environmental burden, with securing safety. As results, sodium cooled fast reactor is well suited to the development targets. LBE cooled fast rector would have a potential to attain the development targets. Helium gas cooled fast reactor would have the great potential for high thermal efficiency and multipurpose energy system. And water cooled fast reactor has the advantage that there are many experiences with LWR. Furthermore the crucial issues for technical feasibility are also clarified as road map of key technology development for each concept.
