3 Westinghouse and Drivers for Nuclear Power 3

4 Westinghouse Electric Company Westinghouse Electric Company provides fuel, services, technology, plant designs and equipment to utility customers in the worldwide commercial nuclear electric power industry More than 60 years of nuclear experience Nearly 50 percent of the nuclear power plants in operation worldwide, and nearly 60 percent in the United States, are based on Westinghouse technology We are the only company operating under the name of George Westinghouse s original company 4

5 Westinghouse Electric Company Background Founded in 1886 by George Westinghouse Responsible for some of the world s important achievements: -AC technology -1 st commercial radio broadcast (KDKA-1920) -USS Nautilus (1954) -Commercial nuclear power (Shippingport, PA 1957) Westinghouse Non- 5

6 The Need for Nuclear Continues to Exist Key Drivers Not Just An Economic Calculus: Energy security/energy independence Clean, safe base-load source of energy Significant source of jobs and economic benefit Long-term reliable energy source/low operating costs 6

7 Nuclear The Most Cost-Effective Source of Energy for the Future Source: Ameren Missouri Integrated Resource Plan

8 Nuclear Technology Evolution 8

9 Nuclear Technology Continues to Evolve 9

10 The Key to New Designs: Lessons Learned - Standardized, di d Simpler, and Safer Standardized designs Pre-engineered Pre-licensed Increased levels of safety Easier to operate and maintain Cost basis that t can compete with other energy sources High degree of certainty for schedule and cost Reduced construction time and cost 10

12 AP1000 Plant is Different! Simple, Practical, Standardized and Innovative A compact station 3415 MWt. Primary system, 1117 Mwe 2-loops, 2 steam generators 12

13 AP The Most Advanced Design Under Construction AP1000 plant is a breakthrough in technology and design. Simplicity and standardization in Design through reduced number of components and bulk commodities Simplicity in Safety through the use of passive safety systems Simplicity in Construction through modularization Simplicity in Procurement through standardization of components and plant design Simplicity in Operation and Maintenance through the use of proven systems and components, and man-machine interface advancements Incorporates constructability, operability, maintainability, and reliability into the design, achieving superior economics 13

14 Achieved Design Goals Utility customer reviews ensured incorporation of Lessons Learned from Operators Proven technology and components were used to eliminate technology risk. Standard design completed prior to construction. Safety systems achieved higher level of safety by employing passive technology: No safety related AC No safety related pumps No safety related ventilation systems No safety ygrade diesel generators 14

15 Proven and Improved Reactor Coolant System Reactor Vessel houses 157 fuel assembly core: Longer vessel accommodates 4.27 m (14 ft.) fuel. Ring forged construction: no welds in core region. Improved materials: 60 year design life Top-mounted in-core instrumentation: no penetrations in bottom vessel Delta 125 Steam Generators Excellent operating experience in U.S. Canned Reactor Coolant Motor Pumps mounted in Steam Generator lower head Eliminates RCP shaft seals Excellent operating experience Simplified main coolant loops with curved pipes to reduce welds 15

16 Simplicity in Safety Design Passive Technology Employs Natural Forces Evaporation Condensation Natural Circulation Compressed gasses (nitrogen, air) System performance has been proven by extensive testing and approved by the U.S. NRC 16

17 Passive Core Cooling System Simple 2-loop reactor coolant system with canned motor pumps Use of passive safety systems Long-term safe shutdown state: 72 hours without t operator action 17
