The failure (or blockage) of the drains could result in channeling water to the service water pump motors during design basis rain events. The licensee entered this issue in their corrective action program as Condition Report ANO-2-2008-1302. The finding was more than minor because it was similar to nonminor Maintenance Rule Example 7.b in NRC Manual Chapter 0612, Appendix E, Examples of Minor Issues, in that the problem could involve degraded equipment performance. This finding had very low safety significance because the failure to properly categorize failures in accordance with the Maintenance Rule Program did not create, in itself, additional operability or functionality concerns. The inspectors determined that the finding did not have a crosscutting aspect because the opportunity to identify that performance monitoring was inadequate had not occurred recently and therefore was not indicative of current licensee performanc |
