Hydrodynamics and heat transfer aspects of corium-water interactions: Interim report
The results of reactor-material experiments are described in which molten corium entered a scaled mock-up of the reactor cavity region of a PWR containment. The experiments address ex-vessel cavity interactions such as corium quench and steam generation rates (for those cases in which water is present in the cavity), hydrodynamic dispersal of water and corim from the cavity, hydrogen generation, containment atmosphere heatup by dispersed corium, and debris characterization. Generic aspects of corium/water mixing, fragmentation, and quench were also investigated. The results include extensive modeling of the hydrodynamic and heat transfer processes and application of the models to the full size reactor system.
