Overview of Inspection Findings
- Failure To Protect Cables Potentially Affected By Fires
- Inconsistency Between Safe Shutdown Analysis And Implementing Procedure
- Some Non-feasible Manual Actions
- Technical Compliance o 8 Hr Battery Backed Emergency Lighting i Manual Actions Not Approved
< § Progress Energy 5
Summary of Root Causes l *Post-Fire Circuit Analysis
- Errors In Analysis o Procedures. Allowed Use Of Manual Action In Lieu Of Circuit Protection Fo'r 3.G.2 Fire Areas From Initial Plant Licensing Efforts In Remote Shutdown P HNP Understanding Of Standards For Acceptability, Of Manual Actions Changed In August 2002 based on industry OE (ANO and NRC/NEI meetings) sG -Progress Energy 6
Summary of Root Causes I
. Operational Implementation
) AOP-036, Safe Shutdown Validation
) Lack Of Specific Criteria For Manual Action Feasibility
- Assessments Focused On Conventional Fire Protection - Barriers, Detection, Suppression, Equipment Impairments M.,

- Valves are required to remain shut to prevent transfer of water from the RWST to the containment recirculation sump.
- Water used for charging would not be available from its alternate suction source (i.e., the RWST) credited by the SSA.
