| Title | Failure to Establish Goals and Monitor the Performance of the Uninterruptible Power Supply Air Conditioning System |
| Description | The inspectors identified a non-cited violation of 10 CFR 50.65(a)(1) for the failure to establish performance goals and perform monitoring to ensure the uninterruptible power supply air conditioning unit X-01 was capable of performing its intended function. Specifically, the licensee failed to include unavailability hours that caused the equipment to exceed the performance criteria. The licensee planned to establish goals for the system. The licensee entered the finding into the corrective action program as Condition Report CR-2014-010188. The failure to establish goals and monitor the performance of the uninterruptible power supply air conditioning system was a performance deficiency. 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 to ensure the availability and reliability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, Attachment 04, Initial Characterization of Findings, and Appendix A, Exhibit 2, Mitigating System Screening Questions, the finding was determined to be of very low safety significance (Green) because the finding did not represent an actual loss of safety function of a system and did not represent an actual loss of a technical specification train for greater than its allowed outage time. The finding has a human performance cross-cutting aspect associated with procedure adherence because the engineer failed to use human error reduction techniques when following procedure [H.8]. |
