| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, provides, in part, that procedures shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Contrary to this requirement, on April 17, 2007, the licensee failed to verify the blocking relay for the Unit 2 pressurizer PORVs were closed upon system restoration. This would have prevented the PORVs from opening in an over-pressurization event. Upon discovery, the licensee measured the resistance across the relay contacts and verified the contacts were closed. This was identified in the licensees CAP as CR 08-5642. This finding is of very low safety significance because the pressurizer safety valves are of a large enough size to depressurize the RCS in the event of an overpressure condition |
