Abstract

The invention discloses an auxiliary heating system in a liquid state heavy metal cooling natural circulating pool type reactor. The system comprises a gas storing tank, a filter, a gas heater, a fan, a gas input tube, an inner-layer thermal insulation plate, an outer-layer thermal insulation plate, a bottom heating ring, a gas output tube, a reactor core coolant entrance baffle, a pipeline fixing steel plate, and pipelines and valves connected between the devices. The system realizes the function of assisting in heating liquid state metal in a main vessel of the liquid state metal cooling pool type reactor, has a simple structure, is convenient to start, can build large-space natural circulation of the liquid state heavy metal in the main vessel even if the reactor is at low power or in shutdown condition after being put into operation, guarantees the temperature of the liquid state heavy metal to be above the melting point, and effectively improves the reliability and safety of the reactor.

Description

technical field [0001] The invention belongs to the technical field of reactor system component design, and in particular relates to an auxiliary heating system inside a liquid heavy metal cooling natural circulation pool type reactor. Background technique [0002] The liquid heavy metal cooling natural circulation pool reactor adopts an integrated design, and all reactor components are submerged in the main container, which greatly reduces the probability of loss of primary coolant accident (LOCA); the main container is loaded with a large amount of liquid heavy metals, making The reactor has good thermal inertia; at the same time, using the good natural circulation characteristics of liquid heavy metals, the main coolant system is driven by natural circulation, which saves the expensive and complex manufacturing process of liquid metal-driven pumps, and the primary circuit of the reactor will not have loss of flow accidents (LOFA), which improves the economy and reliabilit...
