Assessment of the conditions of heat exchange in a pool of spent nuclear fuel from the account of effect of evaporation

Abstract

Provides a model for the assessment of processes of heat transfer in the basins of excerpts of spent nuclear fuel, with various levels of flooding and the effects of evaporation. To heat flow due to surface evaporation can be significant (up to 20–30%) the amount of total heat sink and must be taken into account in the analysis of accidents and for the first time after unloading spent nuclear fuel from the reactor. The results of this work can be used to analyze the security of storage of spent nuclear fuel in some reactor basins excerpts.
