ナトリウム冷却高速炉の炉心損傷事故時における溶融炉心物質の制御棒案内管(CRGT)を通じた炉心領域からの流出挙動に係る現象把握のため、CRGTを模擬したダクト状構造体に模擬溶融炉心物質(溶融アルミナ)を投入する炉外試験を実施し、試験データの分析を行った。

To clarify the molten material outflow behavior from the reactor core region through the control rod guide tube(CRGT) in the core disruptive accident of SFR, the out-of-pile tests simulating the molten material dropping into the CRGT, they are imitated by the molten alumina and the stainless cup respectively, were conducted. In this presentation, the evaluation result of the tests will be reported.
