Abstract

The invention discloses a liquid nuclear fuel heat pipe reactor power supply system and a method for recompressing Brayton cycle. Heat generated by liquid nuclear fuel in a reactor core enables liquidpotassium in a heat pipe to be evaporated and then moved to a heat pipe condensation section, and the heat is transferred to a working medium in a recompression Brayton cycle system through a heat pipe cold end heat exchanger in the condensation section; the working medium does work in a turbine; the working medium sequentially passes through a high-temperature heat regenerator and a low-temperature heat regenerator, then one part of the working medium enters a main compressor after being cooled by a cooler, the other part of the working medium enters a recompressor, and the compressed working medium enters the heat pipe cold end heat exchanger to be heated after being preheated by the heat regenerator, so that a closed recompression Brayton cycle is formed. In the energy conversion system, recompression circulation with helium as a working medium is adopted, and the requirements for small size and high efficiency of a nuclear power system can be met.

Description

technical field [0001] The invention belongs to the technical field of nuclear reactor system design, in particular to a liquid nuclear fuel heat pipe reactor power supply system and method using a recompression Brayton cycle. Background technique [0002] At present, the conventional pressurized water reactor adopts the primary loop reactor coolant cycle and the secondary loop Rankine steam cycle to convert and transfer heat; however, the conventional pressurized water reactor system has a lot of equipment and occupies a large area, and the supporting safety facilities are complicated. Power applications are more limited. [0003] Therefore, it is necessary to design a reactor that can export the heat of the reactor through heat pipes, and then perform energy conversion through a closed Brayton cycle, so that the entire reactor device is compact and can meet the needs of miniaturization of the reactor device. Contents of the invention [0004] In order to solve the probl...
