Liquid metal magnetofluid integral reactor

Abstract

The invention discloses a liquid metal magnetofluid integral reactor, which internally comprises a reactor pressure vessel, reactor internals, a reactor core, magnets and gas-liquid separators. The reactor pressure vessel comprises a barrel, a cover and a bottom seal, the cover covers the top of the barrel which is cylindrical approximately, and the bottom seal is supported at the bottom of the barrel. The reactor is externally provided with thermodynamic working medium pipes, drum control rods, heat pipe radiators and a shielding structure. The liquid metal magnetofluid integral reactor is applicable to a fast reactor and also suitable for other durable heat sources such as isotope heat sources and is wide in structural size and output power adjustable range.

Description

technical field [0001] The invention belongs to the technical field of small space nuclear power devices, and in particular relates to a liquid metal magnetofluid integrated micro-reactor with full-environment automatic circulation capability. Background technique [0002] As the clean energy that is most likely to achieve large-scale and stable power generation, nuclear energy is one of the important ways to alleviate the contradiction between the environment and energy demand. The key to the application of nuclear energy lies in its safety. With the development of nuclear power technology, third-generation and fourth-generation nuclear power systems generally have passive safety features such as natural circulation of full power or partial power, and passive waste heat discharge. [0003] At the same time, with the expansion of the scope of human space exploration and the extension of exploration time, it has become an important requirement for space exploration to be able...

Problems solved by technology

However, the thermocouple conversion device has poor radiation resistance and low energy conversion efficiency - to achieve high conversion efficiency, it must have a very high hot end temperature. Therefore, Europe, the United States and my country are also vigorously promoting the Stirling cycle. Research on energy conversion methods such as closed Brayton cycle; the latter has high energy conversion efficiency, but as an energy conversion unit, compared with a thermocouple, the equipment per unit conversion power has a larger mass, a more complicated mechanical structure, and more moving parts. Many, especially closed Brayton cycles
