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

Abstract

The invention discloses a thermoelectric conversion integrated reactor with a turbine. A turbine engine is added based on a Stirling type thermoelectric conversion integrated reactor, so that output power is remarkably improved. A reactor internal comprises a reactor pressure vessel, reactor internals, a reactor core, an inner shield, an electric generator, a starting engine, a turbine and a gas compressor, the reactor pressure vessel comprises a cylinder, a cover and a bottom sealing head, the cylinder is similar to a cylindrical shape, the cover is arranged at the top of the cylinder in a covering manner, the bottom sealing head is supported at the bottom of the cylinder, and a reactor external comprises a drum control rod and a heat pipe cooler. A basic idea of the reactor is applicableto fast reactors, also applicable to thermal reactor and further applicable to other persistent heat sources such as isotope heat sources.

Description

technical field [0001] The invention belongs to the technical field of space small-scale nuclear power devices, and in particular relates to a thermoelectric conversion integrated micro-reactor equipped with a turbine and equipped with a 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...
