System for exporting heat of marine nuclear power platform

Abstract

The invention discloses a system for exporting heat of an ocean nuclear power platform and relates to the field of heat dissipation processing, the system comprises a heat leading-out part and a heatdissipation part, the heat leading-out part comprises a heat pipe section connected with a reaction push pressure container and used for leading out hot water in the reaction push pressure container,and a cold pipe section connected with the reaction push pressure container and used for enabling cold water formed after the hot water led out of the heat pipe section is cooled to flow back to the reaction push pressure container. The heat dissipation part is a separated heat exchange component, one end of the heat dissipation part is connected with the heat pipe section to cool hot water in theheat pipe section to form cold water, and the other end of the heat dissipation part is connected with the cold pipe section to guide the formed cold water into the cold pipe section. The reliabilityand economy of the ocean nuclear power platform can be greatly improved, and meanwhile the operation risk of the subsequent ocean nuclear power platform is reduced.

Description

technical field [0001] The invention relates to the field of heat dissipation treatment, in particular to a system for deriving heat from a marine nuclear power platform. Background technique [0002] The marine nuclear power platform is an offshore floating nuclear power plant. A platform is equipped with 1 to 2 reactors of a certain nuclear power size according to actual needs, so as to provide certain products and services according to user needs, such as power supply for drilling platforms and fresh water, and power supply for islands and reefs , comprehensive support for ocean-going fleets, power supply for deep-sea exploration and mining, etc., marine nuclear power platforms can greatly meet the needs of scientific research, detection and other fields. [0003] For the nuclear power plant in the marine nuclear power platform, in order to ensure the safety during operation and the nuclear safety after the accident, the following three nuclear safety elements need to be ...

AI Technical Summary

Problems solved by technology

For the control of reactivity, the control rods will remain inserted into the reactor core under nuclear power plant shutdown or accident conditions, so the reactivity is controllable; for the export of core waste heat, onshore nuclear power and offshore The floating small reactor is equipped with a special heat export system, which can quickly export the waste heat of the core in the short to medium term after the accident. For example, the second-generation nuclear power requires that the heat can be exported within 24 hours, and the third-generation nuclear power requires that the heat can be exported within 72 hours. The category requires additional measures, and the economic cost is high
