Radiative cooling and solidification of core melt droplets

DOI: 10.1615/thermopedia.000214


The problem of melt-water interaction is especially important for analysis of hypothetical severe accidents in light water nuclear reactors. A severe accident involves melting of the core and possible subsequent interaction of the core melt (UO2-ZrO2 composition) with water. The fuel-coolant interaction (FCI) may lead to steam explosion with a significant part of the melt thermal energy converted into the mechanical energy of the detonation wave (Corradini et al., 1988; Fletcher and Anderson, 1990; Fletche ...
