A research project has been started for thermophysical property evaluation of eutectic melt composed of B4C as control rod material and stainless steel (SS), eutectic reaction experiments, material analysis, physical modelling of eutectic reaction and reactor application analyses in order to simulate the B4C-SS eutectic melting and relocation behaviors in core disruptive accident of sodium-coold fast reactor. This paper reports the project overview and the first year (JFY 2016) outcomes.
