NUCLEAR REACTOR Russian patent published in 2021 - IPC G21D1/00 B63B35/44 

FIELD: nuclear power industry.

SUBSTANCE: invention relates to a nuclear reactor. In the claimed reactor, heat exchange is provided by using a radially sectioned thermal chamber of the reactor, which, along with sections containing assemblies of solid-state heat transfer elements, includes sections containing assemblies of thermal capsules-heat pipes that do not have as such adiabatic sections between evaporative and condenser sections. Each thermal capsule in the assembly is formed by a single cylindrical case for evaporative and condenser sections - a sealed capsule with a thickness of heat-conducting walls sufficient for heat transfer from the heated evaporative section necessary for melting a solid coolant in the condenser section of thermal power. Assemblies of thermal capsules in sections, as well as assemblies of solid-state heat ducts, are hermetically passed through the bottom of a reactor core and the radiation-protective bottom of the thermal chamber. Sections with assemblies of thermal capsules are separated from each other by intersectional walls and are hydraulically connected to each other and to sections with assemblies of solid-state heat ducts by slit cavities with the possibility of sequential passage of the working coolant through heating channels of all sections alternately, with its input through an input annular collector into heating channels of the outer section and output from heating channels of the central section into the cavity of its output collector.

EFFECT: increase in the power of the heat sink from the core and the heating temperature of the working coolant.
