Na冷却高速炉のNa-コンクリート反応(SCR)に係る実験を行い、反応生成物の堆積効果により同反応が次第に停止する現象を明らかにした。また、実験後に採取した反応生成物の諸物性(密度, 比熱, 融点等)を測定した。

Sodium-concrete reaction (SCR) experiments in sodium-cooled fast reactors were performed to reveal the phenomena that the reaction gradually terminates by the sedimentation effect of the reaction products. In addition, some physical properties of the reaction products (density, specific heat, melting point) were measured after SCR experiment.
