1 New Nuclear Plants in the United States
AP1000 Standard Design: Ready for the Nuclear Renaissance The Current Status of New Nuclear Plants in the United States George Davis Westinghouse Electric Company

2 New Nuclear Plants Being Planned or Built to Help Improve the Environment
Issues driving interest in nuclear energy: Avoiding emissions Providing reliable, economic base-load electricity generation Improving energy security Reducing energy imports Re-building U.S. manufacturing infrastructure Creating export opportunities Construction of new nuclear plants underway overseas Regulatory approval of new plants underway in the U.S.

3 New NRC Licensing Process Will Be Completed Before Construction Begins
Early Site Permit (ESP) Combined Construction & Operating License (COL) Construction ITAAC met Operation Design Certification

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.

12 Simplification Reduces Costs to Build and Operate AP1000

13 Modularization Reduces Construction Schedule and Risks
Pump/Valve Module Module Type Structural Piping Mechanical Equipment Electrical Equipment TOTAL Number 122 154 55 11 342 Structural Module Raceway Module Depressurization Module

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
