Abstract:
The paper is devoted to the analysis of existing options of under-reactor melt traps, designs and
disadvantages of these traps. A variation of its own under-reactor melt trap with a heat-resistant composite
coating with a fluidized bed is proposed. The description of facility for experimental studies of the heat-resistant
composite coating with the fluidized bed is presented. The results of a thermal calculation of the variation of the
under-reactor trap with fluidized bed melt are presented. Thermal calculations showed that an increase in the
average temperature of the melt is less intense in the model of an under-reactor trap with a fluidized bed, due to
heat removal from the corium to the metal to complete the phase transition.
