1New Nuclear Plants in the United States AP1000 Standard Design: Ready for the Nuclear RenaissanceThe Current Status ofNew Nuclear Plants in the United StatesGeorge DavisWestinghouse Electric Company
2New Nuclear Plants Being Planned or Built to Help Improve the Environment Issues driving interest in nuclear energy:Avoiding emissionsProviding reliable, economic base-load electricity generationImproving energy securityReducing energy importsRe-building U.S. manufacturing infrastructureCreating export opportunitiesConstruction of new nuclear plants underway overseasRegulatory approval of new plants underway in the U.S.
3New NRC Licensing Process Will Be Completed Before Construction Begins Early Site Permit(ESP)Combined Construction & Operating License (COL)ConstructionITAAC metOperationDesign Certification
4Current and Planned License Applications for New Nuclear Plants Source: Nuclear Regulatory Commission
7Westinghouse Has Orders for 8 AP1000 Units – So Far China Projects (w/ first unit operational in 2013):Sanmen (2 units)Haiyang (2 units)U.S. Projects (w/ first unit operational in 2016):Vogtle (2 units)Summer (2 units)Both U.S. projects pending state regulatory approvalsContracts for remainder of U.S. projects (10 units) in varying stages of negotiation
8AP1000 Construction Underway at Sanmen Site in China Excavation commenced in February 2008First concrete scheduled for March 2009Commercial operation scheduled for November 2013
9Machining of Heavy Component Forgings in Korea RV-Transition RingSG-Lower ShellSG-TubesheetWestinghouse has begun manufacturing at Doosan for China projectsWestinghouse has the long-lead materials on order for China projectsRV-Lower Shell
10Containment Vessel Plate Fabrication in China Westinghouse has built a global supply chain for China projectsThis supply chain is localized in ChinaWestinghouse partners are also transferring technology
11Simplification of Design, Using Passive Features, Improves Safety Typical PWRAP1000Passive 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.
