Title | Inadequate Procedure Results in Inoperable Essential Pump |
Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion VII, Control of Purchased Material, Equipment, and Services, associated with the licensees failure to have adequate receipt inspection procedures to establish measures to assure that purchased material, equipment, and services conform to the procurement documents. Specifically, using the station procedure for the receipt inspection of the essential motor for the residual heat removal service water booster pump, the licensee failed to identify loose bearing cap bolting. The motor was subsequently installed in the plant for ten months before the degraded condition was identified. The licensee entered this issue into their corrective action program with CR CNS 2011-04643. Corrective actions resulted in revised receipt inspection requirements. The failure to have adequate receipt inspection procedures to establish measures to assure that purchased material, equipment, and services conform to procurement documents is a performance deficiency. The performance deficiency was more than minor because it adversely impacts the equipment performance attribute of the Mitigating Systems Cornerstone, and adversely 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). Using Manual Chapter 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding screened as potentially risk significant since the finding represents an actual loss of safety function of a single train for greater than its Technical Specification allowed outage time. When evaluated per Manual Chapter 0609, Appendix A, Determining the Significance of Reactor Inspection Findings for At-Power Situations, and the Cooper Phase 2 pre-solved table item, One RHRSWBP, the inspectors determined this finding to be potentially risk significant. The finding was forwarded to a senior reactor analyst for review. The senior reactor analyst performed the Phase 3 analysis and determined that the finding was of very low safety significance. This finding did not have a cross-cutting aspect since the receipt inspection took place greater than three years ago and, therefore, the finding is not reflective of current performance. |
