METAL-CONCRETE NUCLEAR REACTOR VESSEL WITH LIQUID-METAL HEAT EXCHANGER Russian patent published in 2017 - IPC G21D1/00 

FIELD: physics.

SUBSTANCE: vessel includes a metal-concrete glass with a bottom and a hermetic overlap of the inner cavity of the glass. The glass contains a concrete filler from the first heat-insulating, heat-resistant reinforced concrete and is installed by means of an underlying concrete interlayer of identical concrete on the base plate of the building part of the reactor compartment inside the enclosing structure filled with the second heat-insulating, heat-resistant reinforced concrete, the strength and thermal conductivity of which are lower than those of the first concrete. The enclosing structure protrudes above the glass and covers the latter with a radial clearance to form a cavity, in which an annular support element is formed on the outside of the glass, with the formation above it of a volume for accommodating the equipment of the reactor installation. The volume under the annular support element is filled with the first heat-insulating, heat-resistant reinforced concrete. The inner cavity of the glass on the bottom of the latter is made of a monolithic construction of heat-conducting, heat-resistant reinforced concrete, the strength and thermal conductivity of which are higher than those of the first concrete, with the formation of a tank for a liquid-metal coolant. The tank is provided with a metal shell, under which the pipelines of the heating system of the said tank construction are installed in the concrete filler. The pipelines of the cooling system are installed in the underlying concrete interlayer and in the enclosing structure from the side of the construction part of the reactor compartment.

EFFECT: expanding the functionality of the nuclear reactor body.
