| Title | Failure to Implement Corrective Actions for 2A Service Water Pump Motor Epoxy Voiding |
| Description | The inspectors identified a Green, self-revealing, non-cited viola.tion of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, in that FENOC did not take corrective actions to prevent recurrence of a significant condition adverse to quality. Specifically, FENOC failed to implement corrective actions following the 2A service water pump motor failure in 2005, which resulted in another failure of the same pump motor in 2011. FENOC implemented the corrective actions to prevent recurrence identified following the 2005 failure for the rewind of 2SWS-P21A motor in July 2011. FENOC documented this issue in their corrective action program as condition report 11-96293. The inspectors determined that FENOC\'s failure to prevent recurrence of a significant condition adverse to quality was a performance deficiency. Specifically, FENOC failed to implement corrective actions to prevent recurrence of a turn-to-turn winding failure of the 2A service water pump due to excessive voiding in the epoxy of the stator end windings. This self-revealing finding is more than minor because it was associated with the equipment performance attribute of the Initiating Events cornerstone and adversely impacted the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors evaluated the significance of this finding using IMC 0609.04, Phase 1 - Initial Screening and Characterization of Findings, for the initiating events cornerstone. The inspectors determined that the finding was of very low safety significance (Green) because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or function would be unavailable. The inspectors determined that this finding had no cross cutting aspect because it is not reflective of current plant performance. Specifically, the actual performance deficiency occurred in 2005 and FENOC implemented corrective actions from the 2005 root cause evaluation for the 2011 rewind of the 2A service water pump motor. |
