| Title | Failure to Establish an Inspection Schedule of the Dry Cooling Towers |
| Description | The inspectors reviewed a self-revealing, non-cited violation of Technical Specification 6.8.1.a and Regulatory Guide 1.33, Revision 2, Appendix A, for failure of the licensee to develop a preventative maintenance schedule for inspections of safety-related equipment. Specifically, the licensee did not develop a preventative maintenance schedule to visually inspect all portions of the dry cooling towers. The licensee entered this condition into their corrective action program as condition report CR-WF3-2014-04930 and CR-WF3- 2014-06100. The licensee developed preventative maintenance tasks to inspect the dry cooling tower tubes, including disassembly where necessary, to restore compliance. The inspectors determined that the performance deficiency was more than minor because it was associated with the Equipment Performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to inspect portions of the dry cooling towers prevented the licensee from identifying corrosion that eventually degraded the system enough to cause a leak. The inspectors determined the finding had very low safety significance (Green) because it did not affect the design or qualification of the system, did not represent the loss of a safety system or function, did not represent the loss of function of at least a single train for greater than its Technical Specification allowed outage time, and did not represent an actual loss of function of one or more non-Technical Specification trains of equipment. The inspectors concluded that the finding had a cross-cutting aspect in the area of Problem Identification and Resolution, Identification, because the licensee did not implement a corrective action program with a low threshold for identifying issues [P.1] (Section 1R19). |
