FIELD: electricity-producing industry.
SUBSTANCE: heat transport main circuit system is equipped with the system of gas supply into the bottom mounting sockets, where the FA bottom nozzles are installed, and also with the injector for the gas priming into the heat transfer in the shape of the size-defined gas bubbles in water: of a size, which is greater than critical size to exclude the bubbles collapse, and of a size, which is lower than the fuel lattice spacing difference and the fuel element diameter for the exclusion of the gaseous cavities formation in the FA. The reactor assembly is supplied with the degassing system for removing gas from the heat transfer into the gas supply system for the gas multiple uses. It can be, for example, helium - the chemically inactive gas with high thermal conductivity - in the function of the gas.
EFFECT: possibility of the local correction of the in-reactor-core flux spectrum.
