| Title | |
| Description | The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to follow procedure for brazing copper joints. Specifically, personnel failed to follow procedure and exercise sufficient care to assure the copper tubing was not overheated during a brazing activity. As a result, personnel overheated copper joints and caused the inoperability of an uninterruptible power supply air conditioning unit when the component developed a leak
The licensee repaired the leak to the uninterruptible power supply air conditioning unit. The licensee entered the finding into the corrective action program as Condition Repor CR-2013-002298. The failure to follow procedure for brazing copper tubing was a performance deficiency. The performance deficiency was more than minor because it was associated with the human 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 at least a single train of equipment for greater than its technical specification allowed outage time. The inspectors determined that the finding was not representative of current license performance and no cross-cutting aspect was assigned. |
