This is a basic study for building a thermophysical model to simulate the eutectic melting behavior of control rod materials in core disruptive accidents of sodium-cooled fast reactors. The density and surface tension of 2.5mass%B₄C-SS melt have been measured using the ultrahigh-temperature thermophysical property measurement system (PROSPECT).
