Mobile emergency cooling apparatus for spent fuel pool in nuclear power plant

Abstract

The invention belongs to the technical field of nuclear power, and provides a mobile emergency cooling apparatus for a spent fuel pool in a nuclear power plant, and an emergency cooling system for thespent fuel pool. A power device, a circulating cooling pump and a cooling device are integrated on a moving platform to form the mobile emergency cooling apparatus for the spent fuel pool in the nuclear power plant. When the original cooling system of the spent fuel pool goes wrong, the power device drives the circulating cooling pump and the cooling device to work, the circulating cooling pump conveys introduced spent fuel pool water to the cooling device, and the cooling device cools the pool water and sends the cooled pool water to the spent fuel pool in order to achieve cooling of the spent fuel pool. The power device, the circulating cooling pump and the cooling device are integrated on the moving platform, so the mobile emergency cooling apparatus has the advantages of improved device integration degree, improved availability, and convenient coordinated running and fast running speed of all the devices.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular 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 melted, so as...
