| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1.a states, in part, that written procedures shall be implemented covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, of which Section 9 specifies procedures for performing maintenance. Contrary to this, on August 27, 2012, the licensee identified that on August 18, 2012 maintenance personnel failed to verify that an adequate amount of oil was added to the Unit 1 A charging pump speed increaser gearbox following maintenance activities, as required by licensee procedure 0-MPM-0103-01, Preventative Maintenance of Charging/High-Head Safety Injection Pumps, Revision 26. This issue is more than minor because it adversely affected the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences, and the related attribute of human performance. Specifically, the Unit 1 A charging pump was degraded because additional oil needed to be added to ensure that the charging pump could fulfill its safety-related function. The inspectors determined that this finding was of very low safety significance (Green) because the finding did not represent an actual loss of function of at least a single train for greater than its technical specification allowed outage time or two separate safety systems out-of-service for greater than its technical specification allowed outage time. The inspectors determined that the licensee correctly evaluated the finding and developed appropriate corrective action as documented in the licensees CAP as CR486077. |
