Fire Protection System Functional Test Procedure
- Palisades 2018011
- Hydraulic and system flow calcs
- Assumed C-factor of 120 (new pipe)
- Pipe was not new
- Required discharge pressure should have been higher
- TS 5.4.1, Procedures
- Green NCV 8
Failure to Correctly Assess the Suppression System in the CSR in the PRA
- Palisades 2018011 and 2015008
- Certain PRA scenarios assumed suppression of fires and no propagation beyond ZOI
- Significant obstructions at ceiling
- Licensee-identified Green NCV 9
Monitoring Program
- Palisades 2018011 and 2018003
- Failure to set action levels to ensure that assumptions in analysis remain valid
- Revision of FAQ 10-0059
- The MR performance criteria for those SSCs promoted to or already considered high safety significant in the MR can be used as an acceptable action threshold.
- No violation 10
Vulnerability to Cause Secondary Fire due to Unfused Circuit
