| Title | Inadequate Controls for Service Water Pump Procurement |
| Description | A self-revealing non-cited violation (NCV) of 10 CFR 50, Appendix B, Criterion VII, Control of Purchased Material, Equipment, and Services, was identified for the licensees failure to establish measures to assure that the 2E service water pump (SWP) installed on November 22, 2006, conformed to purchase order requirements. The failure to assure that the 2E SWP minimum rotor critical speed met the purchase order design specification resulted in an increased susceptibility of the SWP to resonant vibration, which was a factor that contributed to the pump failure. The licensee entered this event into their corrective action program as CR 2009110325. The finding was determined to be greater than minor because it was associated with the design control attribute of the mitigating systems cornerstone and 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). Specifically, the performance deficiency contributed to the failure of the 2E SWP, and thus impacted the reliability of the service water system. Using Inspection IMC 0609, Significance Determination Process, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, the finding was determined to have very low safety significance (Green) because it did not represent an actual loss of safety function of a single Train for greater than its Technical Specification (TS) allowed outage time. No cross-cutting aspect was identified since the issue was not reflective of current licensee performance, in that the performance deficiency occurred in 2006 |
