| Title | Failure to Adequately Correct and Evaluate aCondition Affecting the ESW Pump and ItsAssociated Discharge Valves (Section 1R17) |
| Description | The inspectors identified a finding having very low safety significance and an associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, for the licensee\\\'s failure to adequately evaluate and take appropriate corrective actions for a condition adverse to quality affecting the Emergency Service Water (ESW) Pump \\\'A\\\' and its associated discharge valve. Specifically, the licensee did not implement adequate actions to ensure that the ESW Pump \\\'A\\\' discharge valve (1P45F0130A) would remain open and would not be damaged during the loss of direct current (DC) Bus ED-1-A while the pump was in operation. In addition, the licensee did not identify and evaluate the impact of this condition on the plant=s safe shutdown equipment in the event of an Appendix R fire in the control room. The licensee entered the issue into their corrective action program. This finding was more than minor because the failure to assure that the ESW Pump \\\'A\\\' discharge valve would remain open and would not be damaged affected the mitigating system corner stone objective of ensuring the availability, reliability and capability of the safety-related components to respond to initiating events to prevent undesirable consequences. The finding was of very low safety significance based on a Phase 1 screening in accordance with IMC 0609, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, because the specific condition/scenario only affected the ESW Pump \\\'A\\\' and its associated discharge valve and it did not exist for the redundant ESW Pump \\\'B\\\'. In addition, safe shutdown components for the Division 2 and/or Division 3 systems would remain available, free of fire damage, to safely shut down the plant in the event of a fire in the control room. The finding has a cross-cutting aspect in the area of problem identification and resolution as defined in Inspection Manual Chapter 0305 P.1(c), because the licensee failed to thoroughly evaluate the problem when it was first identified in 2006.
