This study is a part of the research aimed at constructing a model to simulate the eutectic reaction behavior between control rod material (B₄C) and reactor structural material (SS) in core disruptive accidents of sodium-cooled fast reactors. We report the results of the thermal analysis of SUS316L containing 14, 17 mass% B₄C during melting and solidification using a blackbody radiation type ultra-high temperature thermal analysis method.
