Evaluation of the SLSF P2 loss-of-flow safety experiment

An in-reactor safety experiment was performed in the Sodium Loop Safety Facility with a 19-pin, mixed-oxide fuel bundle that simulated a fast reactor accident. Cladding failure and melting, bundle blockage formation, and fuel melting events occurred slightly later than expected. Postirradiation examination data are consistent with accident scenarios in which molten fuel-steel mixtures disperse from the core midplane due to steel vaporization. Approximately 1 s after reactor scram, a fuel-motion event occurred that caused the upward relocation of the upper steel blockage and shroud failure with the ensuing release of a molten fuel-metal mixture from the original fueled region.
