摘要
The present invention relates to a passive containment vessel cooling system for a concrete containment vessel of a pressurized water reactor. More specifically, the present invention effectively reduces the pressure and temperature rise inside the concrete containment vessel by the heat generated in the transient state of the pressurized water reactor or the loss of coolant in the pressurized water reactor using a thermosiphon and an internal steam condenser. And a passive containment cooling system. The passive containment cooling system of the present invention is installed inside the concrete containment vessel (10) and is installed inside the condenser (1) for condensing steam, and the outside of the containment vessel (10) is raised through the riser (2). The external steam condensation pool 3 for condensing the cooling water by direct contact, and the cooling water whose temperature is increased by the heat transferred to the cooling water in the internal internal steam condenser 1, rises to the steam condensing pool 3 by buoyancy. A thermosiphon composed of a riser 2 and a downcamer 4 installed at a lower end of the electric steam condensing pool 3 to provide a path for supplying the cooling water to the internal steam condenser 1; And a cooling water reservoir (8) and a sprinkler (9) for sprinkling cold water into the containment vessel (10) by nitrogen gas discharged from the extruded nitrogen gas reservoir (5) in accordance with the operation of the drive valve (7). It consists of a watering device.
