Problems solved by technology

However, when a reactor accident occurs and the main vessel ruptures, liquid metal will gradually accumulate in the annular cavity formed by the main vessel and the safety vessel, submerging the gas input pipeline, and the system will not be able to operate normally. At this time, the coolant in the reactor will freeze. danger, which is extremely detrimental to the post-accident treatment of the reactor

Abstract

The invention discloses an auxiliary heating system of a liquid heavy metal cooling natural circulating pool-type reactor. The system comprises a gas storage tank, a filter, a gas heater, a master gas input pipe, a main gas input valve, a main gas input pipe, an extraction opening, a main gas output valve, a main gas output pipe, a gas emergency input valve, a gas emergency input pipe, a gas emergency output valve, a gas emergency output pipe, a master gas output pipe, an air pump, a pipeline and other valves, wherein the pipeline is used for connecting the equipments. By adopting the system, the auxiliary heating function on liquid heavy metal inside the reactor is achieved inside a main container of the liquid heavy metal cooling natural circulating pool-type reactor and a ring cavity formed by a safe container, the system is simple in structure and has independence and reliability, members inside the reactor do not need to be added and started in operation, and the safety of the reactor can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of reactor system component design, in particular to a liquid heavy metal cooling natural circulation pool reactor auxiliary heating system. Background technique [0002] The liquid heavy metal cooling natural circulation pool reactor adopts an integrated design. All the internal components of the reactor are immersed in a container. Probability of coolant loss accidents, with good inherent safety and economy. Its simple working process is: the coolant enters the core from the cold pool, cools the core under the action of natural circulation driving force and flows into the heat pool, the coolant in the heat pool enters the main heat exchanger, and transfers heat to the secondary circuit The coolant flows into the cold pool to form a cycle of coolant circulation. [0003] Liquid heavy metal cooling natural circulation pool reactor uses liquid heavy metal as coolant. When the reactor power is very low, the ...
