| Title | Condition Adverse to Quality not Promptly Identified and Corrected |
| Description | A finding of very low safety significance and associated NCV of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, was identified by the inspectors for the licensees failure to promptly identify and correct a condition adverse to quality on August 6, 2010. Specifically, during the performance of STP NS540002B, B Emergency Service Water Operability Test, the licensee did not identify abnormal, elevated Emergency Service Water (ESW) flow to the B Standby Diesel Generator (SBDG), and the impact on other ESW system Technical Specification (TS) and TS support equipment. The licensee entered the issue into the CAP as CR 582068. The inspectors determined that the issue was a performance deficiency because it was the result of the failure to meet a requirement, and the cause was reasonably within the licensees ability to foresee and correct and should have been prevented. The inspectors determined that the performance deficiency was more than minor and a finding because, if left uncorrected, it had the potential to lead to a more significant safety concern. The inspectors applied IMC 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings to this finding. Under Table 4a, the inspectors answered No to all five questions under the Mitigating Systems Cornerstone Column, and screened the finding as Green. The inspectors determined that the contributing cause that provided the most insight into the performance deficiency affected the cross-cutting area of Problem Identification and Resolution, having corrective action program components, and involving aspects associated with implementing a corrective action program with a low threshold for identifying issues. |
