In core disruptive accidents of sodium-cooled fast reactors, boron carbide used as the control material may melt into molten stainless steel and be widely transferred to the inside and outside of the core region. In this study, a series of tests was conducted to acquire the data regarding melting rate of boron carbide into molten stainless steel and its results were considered.
