Containment Vessel Plate Fabrication in China Westinghouse has built a global supply chain for China projects This supply chain is localized in China Westinghouse partners are also transferring technology
Simplification of Design, Using Passive Features, Improves Safety Typical PWR AP1000 Passive Systems dramatically reduce the number and complexity of active systems. Containment Cooling is accomplished by air and water cooling of the freestanding steel containment vessel. Air cooling enters vents at the top of the shield building. It travels down to the bottom of the air baffle and then up between the baffle and the containment shell. The air exhausts at the center of the shield building roof. Air cooling is supplemented by water cooling from a large tank of water above the containment vessel. No operator action is required. 72 hours of containment water cooling is provided in the PCS tank. No safety-related AC power is required (Diesels) Actuation and monitoring functions are provided from safety-related batteries. The digital protection system activates a few safety related devices. Operator action is not required.
