| Title | Performing prohibited elective maintenance on offsite power during EDG maintenance. |
| Description | A noncited violation of Technical Specification 3.8.1.B.4 was identified when the licensee performed elective maintenance in the switchyard and removed equipment from service that was prohibited by Technical Specifications while in an extended diesel generator outage. The inspectors determined that the failure to implement requirements of Technical Specification 3.8.1.B.4 was a performance deficiency. The finding was more than minor because it is associated with the equipment performance attribute for the mitigating systems cornerstone; and, it 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). The finding was determined to be of very low safety significance because the issue resulted in the Train B offsite power being inoperable, but capable of supplying the safety bus for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Additionally, the cause of the finding has a human performance crosscutting aspect in the area associated with work control. Specifically, Wolf Creek did not ensure STS-IC-805B was appropriately coordinated within organizations to assure plant and human performance during the extended emergency diesel generator allowed outage time H.3(b) (Section 1R13) |
