| Title | Failure to Adequately Monitor the Performance of the Unit 1 Auxiliary Building Roof Drains (4OA5) |
| Description | The inspectors identified a noncited violation of 10 CFR 50.65(a)(1) for the licensee\'s failure to monitor Unit 1 auxiliary building roof drains performance in a manner to provide reasonable assurance that the roof drains were capable of fulfilling their intended function. Licensee personnel have never tested, nor checked, the drains for blockages. The failure (or blockage) of these drains could result in excessive roof loading due to accumulation of water during design basis rain events. Licensee personnel entered this issue in the corrective action program as Condition Report ANO-1-2008-1210. The finding was more than minor because it was similar to nonminor Maintenance Rule, Example 7.a, in NRC Manual Chapter 0612, Appendix E, \"Examples of Minor Issues,\" because significant equipment problems could go undetected. This finding had very low safety significance because the failure to properly categorize failures in accordance with the 10CFR 50.65 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 performance (Section 4OA5). |
