FaCTプロジェクトで概念設計を実施している高速炉JSFRでは、品質の向上と建設工期の短縮を図るためSC造格納容器(SCCV)の採用を計画しており、実用化に向け高温下でのSC構造の構造健全性評価手法の開発や建設工法の検討が行われている。本シリーズでは研究成果に基づき、これまでの採否評価結果を報告する。

A containment vessel made of steel-plate-reinforced concrete (SCCV) is planned to be adopted to Japan Sodium-cooled Fast Reactor (JSFR), whose conceptual design is conducted in the Fast Reactor Cycle Technology Development (FaCT) project. The SCCV is a candidate of innovative technology aimed at improving quality and shortening construction period. Toward its commercialization, the project is developing methods to evaluate the structural integrity of the SCCV under elevated temperature and is also studying construction methods. Based on the research outcome, this paper reports the result of applicability study of the innovative technology.
