摘要: In order to provide a coolant tank for preventing a containment from being recompressed and reheated during the cooling of the containment upon occurrence of a design basis accident and a severe accident and a passive containment cooling system comprising the same, the present invention comprises: a storage tank for storing a coolant; a division part which is arranged within the storage tank and divides the inside of the storage tank into a first storage tank and a second storage tank to separate the coolant; a first heat exchanger which is extended from the storage tank to the containment and cools the containment on the basis of the coolant; and a unidirectional valve which is provided on the division part and allows the coolant of the second storage tank to be introduced into the first storage tank when the water level of the first storage tank is reduced.

摘要: 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.
