The inspectors identified a noncited viola … The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, when, on November 8, 2008, Palo Verde Nuclear Generating Station did not adequately test the emergency diesel generator to verify that a newly identified emergency diesel generator governor issue, would not cause the emergency diesel generators start time to exceed the Technical Specification allowable limit of10 seconds. Palo Verde Nuclear Generating Station did not specify testing requirements and acceptance criteria to ensure continued operability of the affected emergency diesel generators. As an immediate corrective action, Palo Verde Nuclear Generating Station reevaluated the issue and specified additional testing requirements with specific acceptance criteria for the affected emergency diesel generators pending completion of a hardware modification that would eliminate the issue. The licensee documented this performance deficiency in Palo Verde Action Request 3280971.The finding was more than minor because, if left uncorrected, it had the potential to lead to a more significant safety concern; specifically, that emergency diesel generator start time in excess of the Technical Specification allowable maximum may not have been promptly identified. The finding is associated with the mitigating systems cornerstone. The finding was evaluated in accordance with Inspection Manual Chapter 0609.04, and determined to be of very low safety significance because the finding was confirmed not to result in loss of operability or functionality. The finding had a crosscutting aspect in the problem identification and resolution component of the corrective action program because Palo Verde Nuclear Generating Station did not thoroughly evaluate operability of the emergency diesel generators that remained susceptible to governor-related start time degradation (P.1.c)nor-related start time degradation (P.1.c) +
