Background

• Westinghouse fully supports INPO initiative to drive to zero fuel leakers by 2010

- Zero Leaking Fuel a strategic objective since 2004

• Grid-to-rod fretting is the primary PWR leaker mechanism

- Fretting leakers typically occur in thrice burned fuel

Background

• CE 16 Next Generation Fuel is key to promoting zero leakers in CE NSSS

- Significant increase in grid-to-rod fretting margin

" CE NGF features same type of spacer grid as 14x TURBO fuel that has demonstrated improved grid-to-rod fretting performance

- Increases other design and operating margins

° CE 16 NGF LTAs in 1st cycle at Waterford

- Scheduled for exam in December 0 Region deployment planned for Spring 2008 in ANO-2 and Waterford
