Modular Construction

AP600 is Mature Design

• Design Maturity

– 1300 man-year / $400 million design and testing effort

– More than 12,000 design documents completed

– 3D computer model developed

• Includes structures, equipment, small / large pipe, cable trays, ducts ...

• Licensing Maturity

– Very thorough / complete NRC review of AP600

• 110 man-year effort (NRC) over 6 years, $30 million

• Independent, confirmatory plant analysis

• Independent, confirmatory plant testing (ROSA, OSU)

• 7400+ questions answered, no open items

• 380+ meeting with NRC, 43 meetings with ACRS

– NRC Design Certification issued 12/99

Why Develop AP1000?

• AP600 meets industry objectives defined in EPRI ALWR Utility Requirements Document (<4.3 ¢/kwh)

• Electric generation environment has significantly changed due to deregulation

– New target generation cost < 3 ¢/kwh

• AP600 cannot achieve this new target through incremental improvements

• This motivated Westinghouse to consider major uprate alternative

AP600 to AP1000 Design Changes

• Increase Core Length & Number of Assemblies

• Increase Size of Key NSSS Components

– Increased height of Reactor Vessel

– Larger Steam Generators

– Larger canned Reactor Coolant Pumps

– Larger Pressurizer

• Increase Containment Height

• Some Capacity Increases in Passive Safety System Components

• Turbine Island Capacity Increased for Power Rating

AP1000 Design Certification Application

• Formal Application was submitted March 28, 2002– Complete Safety Analysis Report for AP1000 Standard Plant

– Full Probabilistic Risk Assessment (PRA) Report

– Technical Specifications

– Supporting topical reports

• NRC Pre- Certification Review has already established that AP600 testing and safety analysis codes are sufficient for AP1000 design certification.

Capital Cost is Critical Issue for New Plants in U.S.

•Nuclear likely to compete head-to-head against coal plants and natural gas plants

•Nuclear production costs (Fuel plus O&M) already low -- approaching 1 cent/KW-hr.

• Investors will expect payback of capital costs within 20 years of operation

•Overnight capital cost will need to be in the $1000-1300/KWe range for long-term competitiveness with natural gas

AP1000 Business Plan Development

• Developed with US Power Companies to:

– Assess the Economic Competitiveness of AP1000

– Validate the Cost/Price Estimate with Independent (Bechtel) Review

– Develop a Sample Project Implementation Model

• Financial Evaluation Based on a Series of 4 Twin Standard Plants

– Provide a Plan for the Next Steps for Commercialization

– Determine Government Support for Commercialization and Risk Management

AP1000/AP600 Role in U.S. Energy Market• Electricity Demand in the United States is Projected

to Increase

• Westinghouse Supports Industry Goals to Maintain the Nuclear Generation Share of the Market (Maintain 20%)

• Environmental Benefits of Emission Free Nuclear Power - A Future Strength that will be Increasingly Valued

• A Family of Standard AP1000 Plants is Competitive with Current Projected Generation Prices

• DOE and Administration are Providing Increased Support for Near-Term Start of Additional Nuclear Capacity

AP1000 Overview

• Technical Feasibility of AP1000 Established

• Retains AP600 Design Detail

• Retains Credibility of Cost Estimateand Construction Schedule

• Established Regulatory Framework

• AP1000 provides 75% power upratefor 15% increment in capital cost
