The inspectors identified a finding of very low safety significance and associated
NCV of
10 CFR 50, Appendix B, Criterion XVI, Corrective Action, for the failure to promptly correct a
condition adverse to quality associated with an inboard oil leak on the Unit 1
1P11-B CCW pump identified on January 27, 2009. Consequently, the
CCW pump operated in a degraded condition until the pump was taken out of service to address inboard bearing oil leaks on January 31 and February 1, 2009. Specifically, on January 27, 2009, a condition report was written documenting an inboard bearing leak; however, the immediate operability screening was incorrect and the licensees screening process failed to ensure prompt corrective actions were taken to address this
condition adverse to quality. 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 thoroughly evaluate the identified problem while classifying, prioritizing and evaluating for operability and reportability of this
condition adverse to quality. Specifically, licensee personnel did not thoroughly evaluate the
condition adverse to quality associated with the
1P-11B CCW pump on January 27, 2009, such that the prompt corrective actions were appropriately prioritized and evaluated.
