[2E12] Study on Eutectic Melting Behavior of Control Rod Materials in Core Disruptive Accidents of Sodium-Cooled Fast Reactors
(27)Normal Spectral Emissivity, Heat Capacity and Thermal Conductivity of 15mass%B4C-SS Eutectic Molten Material
Keywords:Sodium-cooled fast reactor, boron carbide, stainless steel, emissivity, heat capacity, thermal conductivity
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 normal spectral emissivity, heat capacity and thermal conductivity of the 15mass%B4C-SS melt have been measured using noncontact modulated laser calorimetry with the ultra-high-temperature thermophysical property measurement system (PROSPECT).
