Abstract

The invention discloses an integrated villiaumite cooling high-temperature reactor power system for ships and warships. The integrated villiaumite cooling high-temperature reactor power system comprises a reactor body system, a Brayton power circulation system and a power system circulation loop composed of pipelines and other connecting equipment between the systems. The reactor body system is used as a heat source of a power system, and the Brayton power circulation system performs thermodynamic conversion; according to the system, each device can be modularly processed, manufactured, transported and installed; the Brayton power circulation system has the advantages of being high in heat efficiency, sufficient in power and rapid in power response, and the heat efficiency exceeds 48%; and the system can well adapt to the narrow space on the ships and warships, can output enough power and flexibly track load changes, and has reference significance for development of a new-generation ship and warship nuclear power system.

Description

technical field [0001] The invention belongs to the technical field of advanced nuclear power system development and high-efficiency energy conversion, and specifically relates to an integrated fluoride-salt cooling high-temperature reactor power system for ships. Background technique [0002] Modular small fluorine-salt cooled high-temperature reactor has the advantages of high temperature and low pressure, no water cooling and inherent safety. In addition, because the volumetric heat capacity of fluorine salt is equivalent to that of water, it is 2.75, 4.49 and 233.5 times that of liquid lead-bismuth alloy, liquid sodium and helium , so more heat can be taken away under the same volume of coolant, which has outstanding advantages in reducing the core volume and ensuring a compact structure; the supercritical carbon dioxide power cycle system has outstanding high thermal efficiency, compact structure, flexible control and quick response and other advantages.
