Title: The origin of pressure inhomogeneities at early stages of fuel-coolant interaction and melt fragmentation criteria

Abstract

It is proposed the mechanism of melt fragmentation by fuel-coolant interaction (vapor explosion). The criteria of melt surface fragmentation are formulated for cases subcritical and supercritical temperatures of melt-coolant contact surface. These criteria are in agreement with know experimental data about small scale spontaneous and triggered vapor explosions. 8 refs.
