摘要： An object of the present invention is to provide a cooling water storage reservoir capable of passive cooling a reactor containment building in order to prevent the reactor containment building from being re-pressurized and reheated in the event of a serious accident. The cooling water storage reservoir comprises: a storage tank forming a first storage space in which cooling water is stored; a compartment tank disposed inside the storage tank and forming a second storage space separated from the first storage space; and an inlet which is provided in the compartment tank and allows the cooling water in the first storage space to naturally flow into the second storage space when the water level in the second storage space decreases.
