CONSTITUTION: An integrated passive safe tank(160) is installed at both sides of a containment building in which a pressurizing vessel and a steam generator(120) are installed. A passive core cooling system part injects the coolant inside the integrated passive safe tank into the pressurizing vessel if a coolant loss accident occurs. A passive auxiliary feed water system part comprises a passive feed water cooling heat exchanger(250) installed in the integrated passive safe tank. A passive containment building cooling system part reduces pressure and temperature inside the containment building with the coolant supplied from the integrated passive safe tank. The passive containment building cooling system part comprises a passive containment building cooling heat exchanger(260) installed in the containment building. A passive melting core furnace preserve system part supplies the coolant inside the integrated passive safe tank to a cavity installed at the lower part of the pressure vessel and cools the pressure vessel.
