Mobile emergency cooling device for nuclear power plant spent fuel pool

Abstract

The invention discloses a mobile emergency cooling device for a spent fuel pool of a nuclear power plant, which includes: power equipment, a circulating cooling pump and cooling equipment; wherein the power equipment, circulating cooling pump and cooling equipment are connected in sequence and arranged on the same mobile carrier On the platform, the inlet of the circulating cooling pump is connected to the diversion pipeline connected to the water inlet of the original cooling system of the spent fuel pool through the inlet pipeline, the outlet of the circulating cooling pump is connected to the inlet of the cooling equipment, and the outlet of the cooling equipment is connected to the return water through the outlet pipeline. The pipeline is connected to return the cooled pool water to the spent fuel pool; a return pipeline is connected between the outlet pipeline and the inlet pipeline. Compared with the prior art, the present invention integrates power equipment, circulating cooling pumps and cooling equipment on a mobile carrying platform, which can improve the equipment integration and availability of the mobile emergency cooling device, by connecting the outlet pipeline and the inlet pipeline The return line and the cooling equipment are not easy to scale, and the cooling effect is good.

Description

technical field [0001] The invention belongs to the field of nuclear power, and more specifically, the invention relates to a mobile emergency cooling device for spent fuel pools of nuclear power plants and an emergency cooling system for spent fuel pools. Background technique [0002] The spent fuel pool refers to the storage of spent fuel assemblies discharged from the core during previous refueling in nuclear power plants. Due to the certain decay heat of the spent fuel assembly in the spent fuel pool, the spent fuel pool needs to be cooled by the spent fuel pool cooling system to maintain the pool water temperature below a certain temperature, thereby preventing the temperature of the spent fuel pool under normal working conditions from increasing. If it is too high, it will damage the equipment, suppress the boiling of the spent fuel pool under accident conditions, prevent the water in the spent fuel pool from evaporating and the fuel components will be exposed and melt...
