EMERGENCY COOLING FACILITY FOR SPENT FUEL POOL BUILDING STORING SPENT FUEL USING DECOMMISION NUCLEAR POWER PLANT AND METHOD FOR EMERGENCY COOLING WATER FOR SPENT FUEL POOL BUILDING UISING IT

摘要

A spent fuel storage tank installed with a storage space formed inside by removing the internal facilities and structures of the nuclear reactor containment building of a decommissioned nuclear power plant, and a storage rack installed inside the spent fuel storage tank to store spent fuel, and use Cooling water filled in the storage space of the spent fuel storage tank, an external storage tank installed at an upper position spaced apart from the spent fuel storage tank and storing coolant therein, and the spent fuel storage tank and the external storage tank are connected between the used fuel storage tank and the cooling water inside A flow path is formed through which the fuel is moved, and a heat exchange tube heated by contact with the cooling water of the spent fuel storage tank is connected between the spent fuel storage tank and the external storage tank, and the cooling water cooled in the external storage tank is supplied to the spent fuel storage tank. contains line.
