JSFRでは、建設工期短縮に効果的なSC構造を格納容器に採用することを検討している。SC構造が、一般建築物には実績があるが、高温下での挙動はわかっていない。このため、700度を上限に、高温下でのSC構造の性質を把握するための実験的検討を実施した。

Japan Sodium-Cooled Fast Reactor (JSFR) adopts new concept of containment vessel called steel plate reinforced concrete containment vessel (SCCV). The SCCV is considered to be effective to shorten construction schedule due to elimination of rebar work at a site and so on. Although the SC structure has been used for the buildings of LWR etc, it is important to investigate its characteristics under temperature load to adopt as the containment vessel. This paper describes experimental investigations of characteristics of the SC structure under 700 centigrade(C) at the surface steel plate which is decided assuming hypothetical sodium combustion in the containment vessel to study the potential strength of the SC structure.
