In order to make clear behavior of core melt materials during the core disruptive accident of sodium-cooled fast reactors, analysis was conducted for a simulation experiment in which low-melting-point alloy was dropped into a shallow water pool using the SIMMER code. The present study shows that the validation results for the melt behavior by comparing the analysis with experimental data.
