将来の多様なニーズに対応可能な有望な高速炉サイクルシステムを提案するために、実用化戦略調査研究を進めている。様々な炉システム概念に関する設計研究を実施し、開発目標に対する適合度を評価した。また、各炉システム概念に対する重要な開発課題を抽出し、その開発計画をロードマップとしてとりまとめた。結果として、各炉の特徴や性能の違いを検討し、重要な開発課題と開発期間を明確にした。現在、さらなる検討を進めており、フェーズII末での評価結果を踏まえて、有望概念を提案する予定である。

The Feasibility Study on Commercialized Fast Reactor (FR) Cycle Systems is under way in order to propose prominent FR cycle systems that will respond to the diverse needs of society in the future. The design studies on various FR system concepts have been achieved and then the evaluations of potential to achieve the development targets have been carried out. Crucial issues have been found out for each FR system concept and their development plans for the key technologies are summarized as the roadmap. The characteristics and the differences in performances have been investigated. The crucial issues and the development periods have been clarified. Further investigation is now in progress. The promising concept will be proposed based on result of comparative evaluation at the end of the Phase II study.
