A finding of very low safety significance … 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 on March 7, 2012, following review of apparent cause evaluation (ACE) 01720033 associated with the loss of Low Pressure Coolant Injection (LPCI) loop select capability. Specifically, the inspectors identified several concerns with the implementation of the licensees corrective action program characterization of CR 01720033 that resulted in the inadequate evaluation of cause, extent of cause and condition; and incomplete corrective actions to prevent recurrence. The licensee entered the issue into the CAP as CR 01742201, and was in the process of revising the original causal evaluation and performing an additional ACE to investigate the CAP implementation issues. The inspectors determined that failing to properly determine the cause and take corrective actions to prevent recurrence for LPCI loop select instrument failures represented a performance deficiency. The performance deficiency was determined to be more than minor and a finding because, if left uncorrected, failing to properly determine the cause and take corrective actions to prevent recurrence for significant conditions adverse to quality would have the potential to lead to a more significant safety concern. The inspectors evaluated the finding in accordance with IMC 0609.04, Table 4a. Because the inspectors answered No to all five screening questions under the Mitigating Systems Cornerstone column, the finding screened as very low safety significance (Green). The inspectors determined that the contributing cause that provided the most insight into the performance deficiency was associated with the cross-cutting aspect of Human Performance, having Decision Making components, and involving the licensee making safety-significant or risk-significant decisions using a systematic process, especially when faced with uncertain or unexpected plant conditions, to ensure safety is maintained.onditions, to ensure safety is maintained.
