| Title | Licensee-Identified Violation |
| Description | TS 3.3.14, Emergency Feedwater Pump Initiation Circuitry, required for one or more required Loss of Main Feedwater pump (LOMF) initiation circuits inoperable, that the affected EFW pumps be declared inoperable. Additionally, TS 3.7.5 required, in part, that three EFW pumps shall be operable. Contrary to the above, on October 21, 2009, the licensee identified sixteen instances over the last three years, distributed among all three units, where conditions for declaring the EFW pumps inoperable were met due to a lack of understanding of the effect of the circuitry on operability during unit startup following refueling outages. As a result, the appropriate TS Action Statement of TS 3.7.5, which required the licensee to initiate action to restore one EFW pump to operable status immediately, was not entered as required. The inspectors verified the licensee corrected the procedural inadequacies. This finding is of very low safety significance (Green) because the finding did not represent an actual loss of system safety function. The licensee entered the finding into their CAP as PIP O-09-6670. |
