HEAVY LIQUID METAL COOLANT NUCLEAR REACTOR Russian patent published in 2021 - IPC G21D1/00 G21C9/00 

FIELD: nuclear reactors.

SUBSTANCE: invention relates to a nuclear reactor with a heavy liquid metal coolant. In the inner space of a nuclear reactor, not occupied by the necessary equipment, containers filled with a material that reflects or absorbs neutrons with a heat capacity greater than the heat capacity of the coolant are placed with gaps that ensure the flow of the coolant. Moreover, the containers are placed in such a way that the resulting gaps form channels with a turbulent flow of the coolant for cooling these containers at a flow rate corresponding to the nominal power level of the nuclear reactor.

EFFECT: increasing efficiency of radiation protection of the in-vessel equipment of a nuclear reactor, increasing the heat storage capacity of the primary circuit, reducing the weight of a nuclear reactor and improving its strength characteristics.
