Abstract

The invention relates to the technical field of nuclear reactors, and provides a marine nuclear power platform waste heat removal system which comprises a heat exchange channel, a waste heat circulation loop and a bubble generation device. A liquid inlet and a liquid outlet are formed in the heat exchange channel in the extending direction of the heat exchange channel, and the liquid outlet is formed above the liquid inlet; a cooling fluid is introduced into the heat exchange channel; the waste heat circulation loop is used for introducing a coolant of the reactor, and the coolant is coupled with cooling fluid for heat transfer; an air outlet of the bubble generating device is communicated with the heat exchange channel; bubbles generated by the bubble generating device are used for forming a mixture with the cooling fluid in the heat exchange channel, and the mixture is discharged through the liquid outlet. According to the invention, through the bubbles generated by the bubble generation device, the heat exchange efficiency between the coolant and the cooling fluid is improved under the condition that the reactor is shut down, so that the waste heat of the reactor core can be quickly discharged.

Description

technical field [0001] The invention relates to the technical field of nuclear reactors, in particular to a waste heat discharge system for marine nuclear power platforms. Background technique [0002] The marine nuclear power platform is an organic combination of nuclear power technology and modern ship technology. Its core is to convert the controllable nuclear fission energy into heat and electricity through nuclear power devices, which provides energy security for the development of marine resources and remote sea islands; After the reactor in the marine nuclear power platform is shut down, although the core fission chain reaction has terminated, the delayed neutrons continue to cause partial nuclear fission, and the fission products, neutron capture products decay and other reasons lead to a long time after the shutdown. The inner core will still generate a large amount of waste heat. In order to ensure the safety of the core, the waste heat must be discharged in time. ...
