Finding

Title

Failure to Adequately Monitor the Performance of Roof Drains

Description

The inspectors identified a non-cited violation of 10 CFR 50.65(a)(2), Requirements for monitoring the effectiveness of maintenance at nuclear power plants. Specifically, the licensee failed to appropriately consider the availability of the reactor building, diesel generator building,and control building roof drains when evaluating whether their performance or condition had been demonstrated to be effectively controlled. The licensee entered this issue in their corrective action program as Condition Report CR-CNS-2012-05993. The licensees failure to effectively monitor the performance of maintenance rule scoped equipment in accordance with 10 CFR 50.65(a)(2) was a performance deficiency. The performance deficiency was determined to be more than minor, and is therefore a finding, because it is associated with the protection against the external factors attribute of the Mitigating Systems Cornerstone, in that the failure to appropriately evaluate availability of the roof drains could result in their not being able to perform their intended function when required, thereby affecting the associated cornerstone objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process For Findings At-Power, the finding was determined to have very low safety significance (Green) because the finding did not involve the loss or degradation of equipment or function specifically designed to mitigate a flooding event. The inspectors determined that the apparent cause of this finding was that the licensee had performed an inadequate evaluation with regard to Condition Report CR-CNS-2011-01859 and failed to recognize and correct the lack of appropriate monitoring criteria for the roof drains. Therefore, the finding has a cross-cutting aspect in the area of problem identification and resolution associated with the corrective action component because the licensee failed to thoroughly evaluate problems such that the resolutions address causes.
