In order to clarify the accumulation behavior on the core disruptive accident in sodium cooled fast reactors, an analysis for the experiment in which the low-melting point alloy drop into a shallow water pool was conducted by using SIMMER code. In this presentation, the validation result for the analysis geometry model conducted by the comparison of the calculation result and experimental value is presented.

Simulation using SIMMER-III code was performed for an EAGLE-3 out-of-pile experiment whose objective was to clarify the fragmentation and cooling behavior of molten core material impinging onto a horizontal plate in sodium during core disruptive accidents of sodium-cooled fast reactors. Validation of the analytical model was confirmed by comparing analytical and experimental results.
