| Title | Improperly Classifying the Unit 2 and 3 Containment Cooling Service Water (CCSW) Pump Vault Drain Check-Valves as Non-Safety-Related |
| Description | A finding of very low safety significance and associated non-cited violation of 10 CFR 50, Appendix B, Criterion II, Quality Assurance Program, was identified by the inspectors for the reclassification of the Unit 2 and 3 containment cooling service water (CCSW) pump vault drain check valves from a quality status of safety-related to non-safety-related. The licensee had not yet determined corrective actions for this violation by the end of the inspection period. The finding was determined to be more than minor because the finding, if left uncorrected, would become a more significant safety concern. Specifically, by removing the quality assurance requirements for this part, the licensee reduced the assurance that replacement parts are of sufficient quality to assure reliable service during and following design basis events. The inspectors concluded this finding was associated with the Mitigating Systems Cornerstone. 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. The finding screened as of very low safety significance (Green) because the finding was a qualification deficiency confirmed not to result in loss of operability or functionality. The inspectors did not identify a cross-cutting aspect associated with this finding, primarily because the reclassification occurred in 2004. |
