“…The thermophysical properties of molten mixtures of stainless steel and control rod material (B 4 C) are necessary for the development of computer simulation codes that describe core degradation mechanisms during severe accidents in nuclear power plants involving sodium-cooled fast reactors. 1,2 A thermophysical property database should be built for systems composed of stainless steel and B 4 C; however, reliable data for stainless steel-B 4 C melts are lacking, owing to the difficulty associated with performing experimental measurements. High-temperature melts may, in general, react with container materials, which results in chemical contamination and limits the suitable temperature range for measurements.…”

An electromagnetic levitation technique performed in a static magnetic field was used to measure density, surface tension, normal spectral emissivity, heat capacity, and thermal conductivity of molten 316L stainless steel (SS316L) and SS316L that contained 5 mass % B 4 C. The addition of 5 mass % B 4 C to the SS316L yielded reductions of 111 K, 6%, 19%, and 6% in the liquidus temperature, density, normal spectral emissivity, and thermal conductivity at the liquidus temperature of the SS316L, respectively. The heat capacity increased by 5% with this addition. Although the addition of 5 mass % B 4 C had no clear effect on the surface tensin, sulfur dissolved in the SS316L caused a significant decrease in the surface tension.
