Nuclear power supply system for underwater unmanned submersible vehicle

Abstract

The invention provides a nuclear power supply system for an underwater unmanned submersible vehicle. The nuclear power supply system can improve the inherent safety and unmanned autonomous control capability of a reactor. The system comprises a reactor core, a high-temperature heat pipe, an alkali metal thermoelectric conversion device, a medium-temperature heat pipe, a storage battery and a pressure-resistant shell, wherein the evaporation section of the high-temperature heat pipe is inserted into the reactor core; the condensation section of the high-temperature heat pipe is inserted into the alkali metal thermoelectric conversion device; the alkali metal thermoelectric conversion device comprises a plurality of groups of thermoelectric conversion modules; a heating end of each thermoelectric conversion module is connected with the high-temperature heat pipe; a condensation end of each thermoelectric conversion module is connected with the medium-temperature heat pipe; the condensation section of the medium-temperature heat pipe is connected with the pressure-resistant shell; waste heat is conducted into surrounding seawater; the alkali metal thermoelectric conversion device is further connected with a storage battery; and the alkali metal thermoelectric conversion device converts heat energy into electric energy and stores the electric energy in the storage battery.

Description

technical field [0001] The invention relates to the technical field of nuclear reactor engineering, in particular to a nuclear power supply system which completely operates in a passive mode and is suitable for underwater unmanned submersibles. Background technique [0002] my country has abundant marine resources, but as my country's marine strategy gradually moves from shallow sea to deep sea, insufficient energy supply has become the main technical bottleneck for the development of deep sea equipment. [0003] Nuclear reactors have high power density, no need to consume oxygen, and can work autonomously all day long. They have become a preferred choice for powering deep-sea equipment, especially for infrastructure that requires long-term energy supply, such as deep-sea monitoring stations, manned deep submersibles, and submarine drilling platforms. , The small nuclear reactor power system has incomparable advantages. [0004] At present, different small reactor solutions...
