Nuclear Energy Safe, Clean And Cost-Effective
Nuclear power must continue to be part of the
global energy solution.
4
Westinghouse Electric Company

Westinghouse Electric Company provides fuel,
services, technology, plant design, and equipment
to utility and industrial customers in the
worldwide commercial nuclear electric power
industry
Westinghouse Electric Company Headquarters -
Energy Center Monroeville, Pennsylvania, USA
Nearly 50 percent of the nuclear power plants in
operation worldwide, and nearly 60 percent in the
United States, are based on Westinghouse
technology
5
Three Core Businesses
Nuclear Fuel Single-source fuel provider for PWR,
BWR, VVER, AGR, and Magnox reactors worldwide
Nuclear Power Plants Specializing in the
technology of new nuclear power plants and
component manufacturing
Nuclear Services Maintenance, repair and
replacement of equipment provider of engineering
services and methods for the design, operation
and safety of nuclear power plants worldwide

The AP1000 Is Different

• We have addressed the sins of the past Licensing
  risk, Technology Risk, Design Risk, Construction
  Risk

• No licensing risk licensing complete prior to
  construction
• No technology risk reliance on proven
  technology
• No design risk design complete prior to
  construction
• All of the above reduce construction periods

AP1000Results

• Dramatically safer design
• Simpler design, higher reliability
• Less equipment to maintain
• Increased operating margins
• Smaller staff, which is further reduced by
  automation from advanced process controls

The Leading Choice For New U.S. Nuclear
14
PBMR Nuclear Gas Turbine

• National Strategic Project in South Africa
• High-temperature gas-cooled reactor (900ºC)
• High thermal efficiency
• Recuperative Brayton Cycle
• 400 MWth/165 MWe
• On-line refueling (gt95 capacity factor)
• Maintenance outage once every 6 years
• Metallic materials provenin LWR applications

15
PBMR Safety Concept

• Ceramic coated fuel particles provide primary
  radionuclide barrier
• Helium gas a single phase coolant
• Low power density and large thermal capacity
• Core decay heat removed passively by conduction
  and natural circulation cavity cooling system
• Passive heat transfer and high fuel temperature
  capability preclude core melt
• Added safety margins allow siting in closer
  proximity to public

IRIS International Reactor Innovative and Secure

• Advanced integral light water reactor
• 335 MWe/module
• Innovative, simple design
• Enhanced Safety-by-Design
• International team
• Recognized by Global Nuclear Energy Partnership
  (GNEP) as grid appropriate reactor
• Anticipated competitive economics
• Cogeneration (desalination, district heating)
• NRC pre-application underway
• Design Certification testing program underway
• Interest expressed by several countries
• Projected deployment target 2015 to 2017

Nuclear Fuel Challenges

• More aggressive operational strategies
• Doubled cycle lengths (from 12 to 24 months)
• Increased power density as a result of plant
  power uprates
• Ever-increasing discharge burnups (70 GWd/Tn)
• Increasingly heterogeneous cores (including U/MOX
  cores)
• Advanced fuel designs to meet increased focus on
  fuel economics and reliability
• Highly heterogeneous fuel concepts
• Extensive use of burnable absorbers
• Increased intolerance to unwelcome events
• Zero fuel failure expectations
• Almost perfect cycle length predictions
• Within 1 - 2 days after a 2 year-cycle
