| Title | Failure to Prevent Over voltages on the 480 Vac System During Emergency Diesel Generator Testing |
| Description | The team identified a Green, non-cited violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, which states, in part, Measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected. Specifically, in 2006, the licensee implemented corrective actions per Condition Report 2006-2062, to monitor the voltages for the 480 Vac system to ensure that over-voltages would not occur during emergency diesel generator testing. The licensee implemented voltage monitoring for the B Train 480 Vac system, but failed to monitor voltages of A Train, which had the same vulnerability. The licensee has entered this issue into their corrective action program as Condition Report CR-73209. The team determined that the licensees failure to implement corrective actions into diesel testing Procedure STS KJ-001A was a performance deficiency. This finding was more than minor because it was associated with the Equipment Performance attribute of the Reactor Safety, Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee failed to ensure that over-voltages would not occur during the testing of the A train emergency diesel generator. In accordance with NRC Inspection Manual Chapter 0609, Appendix A, Exhibit 2, the inspectors determined the finding was of very low safety significance (Green), because the finding was not a design deficiency and did not result in the loss of operability or functionality. This finding did not have a cross-cutting aspect because the most significant contributor to the performance deficiency did not reflect current licensee performance. |
