| Title | Licensee-Identified Violation |
| Description | 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, requires, in part, that measures shall be established to assure that conditions adverse to quality are promptly corrected. Contrary to this, the licensee failed to ensure adequate corrective actions were implemented to address degradation of the rubber liner in the 2A conventional service water (CSW) pump discharge elbow, resulting in its failure in August 2010. Several repairs have been performed on the 2A CSW pump elbow liner previously, including September 2005, March 2008, and November 2008. After the failure of the 2A CSW pump elbow liner in August 2010, the issue was entered into the licensees corrective action program as NCR 417194. As corrective actions, the licensee removed the rubber liners from the service water pump discharge elbows, set up a foreign material recovery plan, and implemented engineering change 78094 to coat the elbow internal surfaces with an epoxy composite coating. The finding was determined to be of very low safety significance (Green) because the degraded condition did not result in the inoperability of TS equipment or the unavailability of non-TS risk significant equipment for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Also, the finding was not potentially risk significant due to a seismic, flooding, or severe weather initiating event. |
