Program Health

"* Historical review

INPO Assessment

• Performed July 2002

• INPO Team Leader

+ Five Industry Peers

• Results include Beneficial Practices and Recommendations

• No significant issues identified

INPO Assessment - Beneficial Practices

"* Inspection Assessment - An extensive and critical self assessment was performed on the vessel and internals program and inspection activities.

"* Core Plate Analysis - The analysis of the core plate shows that we can continue operation through the Spring 2006 outage and is based on conservative assumptions.

"* BWRVIP System Health Meeting - An effective tool for sharing information, focusing resources, and aligning individuals on vessel and internalsissues. The meetings will help ensure important information is communicated as the program develops with changing BWRVIP guidelines.

INPO Assessment - Recommendations
