| Title | Failure to Recognize Unit 1 Component Cooling Water Pump Was Inoperable on January 1,2009 |
| Description | The inspectors identified a finding of very low safety significance and associated NCV of Technical Specification (TS) 3.7.7, Component Cooling Water (CCW) System, for the failure to recognize that the Unit 1 1P-11B CCW pump was inoperable. Consequently, the licensee failed to take actions in accordance with TS for an inoperable CCW pump. Specifically, on January 1, 2009, auxiliary operators added a full reservoir (bubbler) of oil to the inboard bearing for the second time in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, due to an oil leak. This abnormal condition was not appropriately characterized by the licensee until after two more oil additions, when a condition report was written to document the oil addition on January 5, 2009. The licensee performed an apparent cause evaluation and implemented corrective actions to address the deficiencies and lessons learned from this finding. The finding was determined to be more than minor in accordance with IMC 0612, Appendix B, Issue Screening, dated December 4, 2008, because the finding was associated with the Mitigating Systems Cornerstone attribute of equipment performance and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, the CCW pump was degraded with an inboard bearing oil leak and may not have been able to fulfill the 30-day mission time of the pump. The inspectors determined the finding could be evaluated using the SDP in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 - Initial Screening and Characterization of Findings, Table 4a for the Mitigating Systems Cornerstone, dated January 10, 2008. The inspectors determined that the finding required a Phase 2 analysis since the finding represented an actual loss of a single train for greater than its TS allowed outage time. The inspectors and senior reactor analyst determined through Phase 2 analysis that this issue is best characterized as a finding of very low safety significance (Green). The inspectors also determined that this finding has a cross-cutting aspect in the area of problem identification and resolution, corrective action program component, because personnel did not use a low threshold for identifying issues. Specifically, licensee personnel failed on three occasions to enter the oil additions into the corrective action program which would have required a Senior Reactor Operator to screen the condition for operability.
