Current risk studies of light water reactors include analysis of phenomena associated with severe accident sequences. These sequences include low probability events in which molten core materials escape in high-system-pressure situations into regions below the reactor pressure vessel, are fragmented into droplets, and swept by blowdown steam (and hydrogen) into the containment atmosphere in sufficient atmosphere. The dispersed molten core droplets could release their latent and sensible heats as well as chemical oxidation energy directly to containment atmosphere in sufficient quantities to cause overpressurization. This study extends understanding of such direct containment heating phenomenology by examining the disposition of heat radiated from the dispersed high-temperatures droplets.
