| Title | Failure to identify procedural inadequacies and non-compliances that contributed to the November 4, 2008 SW pumps foreign material intrusion events |
| Description | The NRC identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, involving two examples of conditions adverse to quality not properly identified and corrected. For the first example, Constellation failed to identify that responsible station personnel did not adhere to the governing procedures for diving operations and foreign material intrusion for the C service water (SW) pump fouling event, and as a consequence, this led to the fouling of the F SW pump on November 4, 2008.For the second example, Constellation failed to identify that inadequate work controls and procedural guidance contributed to the November 4, 2008, SW pump foreign material intrusion events. The failure of Constellation to have identified these procedural noncompliance and adequacy issues is considered a significant weakness in Constellations causal analysis and associated corrective actions for the White PI. This NRC-identified finding supports the basis for a parallel White finding. Constellation entered this finding into their Corrective Action Program (Condition Report No. 2008-08430).This corrective action finding is more than minor because it adversely impacted the equipment performance attribute and the Mitigating Systems Cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the significance of this finding using IMC 0609, Attachment 4, Phase 1 Initial Screening and Characterization of Findings. The finding screened as very low safety significance (Green) because the failure of the C and F SW pumps did not represent an actual loss of safety function of a single train of SW system for greater than its Technical Specification Allowed Outage Time. This finding has a cross-cutting aspect of P.1(c), referring to the area of Problem Identification and Resolution Corrective Action Program, involving the thoroughness and effectiveness of evaluations. |
