COOLING WATER STORAGE RESERVOIR AND NUCLEAR REACTOR BUILDING PASSIVE COOLING SYSTEM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/062915
Kind Code:
A1
Abstract:
In order to provide a cooling water storage reservoir, and a nuclear reactor passive cooling system including the same, the reservoir capable of preventing re-pressurization and reheating of a nuclear reactor building from the cooling of a nuclear reactor building in case of a design basis accident and a major accident, and releasing to the outside vapor of a heat exchanger generated in cooling the reactor building, the present invention comprises: a storage tank in which cooling water is stored; a partition unit which is disposed inside the storage tank, which partitions the inside of the storage tank into a first storage tank and a second storage tank so that the cooling water can be separated and which has an inlet for causing the cooling water of the second storage tank to naturally introduce into the first storage tank according to the water level difference between the first and second storage tanks; a heat exchanger extending from the first storage tank to the inside of the reactor building to cool the reactor building based on the cooling water of the first storage tank; and a steam discharging unit connected to the heat exchanger and discharging the steam generated in the heat exchanger to the outside of the heat exchanger.
