| Title | Failure to Prescribe Motor Driven Auxiliary Feedwater Pump Test Procedures that Accounted for the Allowed Emergency Diesel Generator Frequency Variation |
| Description | The inspectors identified a Green finding and an associated Non-Cited Violation (NCV)of Title 10 of the Code of Federal Regulations (CFR),Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to prescribe motor driven auxiliary feedwater pump test procedures that accounted for the allowed emergency diesel generator frequency variation. Specifically, the motor driven auxiliary feedwater pump surveillance procedures would allow a pump with degraded and unacceptable performance to meet the test acceptance criteria based upon the test being performed at nominal frequency and not accounting for potentially lower, allowable, emergency diesel generator frequency. |
