7. Westinghouse 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 approvals
Contracts for remainder of U.S. projects (10 units) in varying stages of negotiation

8. AP1000 Construction Underway at Sanmen Site in China
Excavation commenced in February 2008
First concrete scheduled for March 2009
Commercial operation scheduled for November 2013

9. Machining of Heavy Component Forgings in Korea
RV-Transition Ring
SG-Lower Shell
SG-Tubesheet
Westinghouse has begun manufacturing at Doosan for China projects
Westinghouse has the long-lead materials on order for China projects
RV-Lower Shell

10. 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

11. 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.

14. Issues Important to Nuclear Energy
Continued public and political support
Stable regulatory environment
Availability of financing
Management of used fuel
Expansion of manufacturing infrastructure
Training of construction workforce
State-level programs that support long-term, stable generating options
Equal treatment with other non-emitting technologies
