FIELD: nuclear equipment.
SUBSTANCE: invention relates to a reactor on molten salts. Reactor comprises an active zone of a nuclear reactor for supporting a nuclear fission reaction, operating on fuel in the form of salt melt. Fuel control system in the form of molten salts removes volume of fuel in form of molten salts from active zone of nuclear reactor to maintain reactivity parameter in interval of design reactivity. Fuel control system in form of salt melt contains fuel replacement system in form of molten salts, which is fluidly connected to the core of the nuclear reactor and replaces the fuel volume in the form of salt melt with the volume of the raw material containing the mixture of the selected reproducing material and the carrier salt. Fuel control system in form of molten salts can contain volume displacement control system, containing one or more solid displacement bodies introduced into the core of the nuclear reactor. Every displacement body can remove volume of fuel in form of salt melt from nuclear reactor core, for example, through overflow system.
EFFECT: technical result is stabilization of fission reaction due to regulation of amount and composition of melt of salts, in particular, without addition of raw material and without removal of lanthanides, as well as reducing the number of nuclear wastes remaining after the end of the nuclear fission reaction.
