The team identified a Green non-cited viol … The team identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion XII, Control of Measuring and Test Equipment, which states, in part, measures shall be established to assure that tools, gages, instruments, and other measuring and testing devices used in activities affecting quality are properly controlled, calibrated, and adjusted at specified periods to maintain accuracy within necessary limits. Specifically, prior to March 16, 2012, the licensee failed to establish measures to assure that pressure and temperature instruments used in monitoring and preventive maintenance for Unit 1 and Unit 2 safety-related 480 Vac load center transformers were calibrated and adjusted at specified periods to maintain accuracy within necessary limits. This finding was entered into the licensees corrective action program as Condition Report CR-ANO-C-2012-00657. The team determined that the failure to calibrate pressure and temperature instruments for Unit 1 and Unit 2 safety-related load center transformers X5, X6, 2X25, and 2X26 was a performance deficiency. This finding 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 licensees programmatic failure to calibrate pressure and temperature instruments for Unit 1 and Unit 2 safety-related 480 Vac load center transformers would challenge the operability of the transformers. In accordance with NRC Inspection Manual Chapter 0609, Attachment 4, Phase 1 Initial Screening and Characterization of Findings, the finding was determined to have very low safety significance (Green) because it was a design or qualification deficiency confirmed not to result in a loss of operability or functionality. Specifically, the licensee confirmed, through portable measurement equipment, that each transformers gas coolant pressure and temperature were not in a condition which challenged operability during the previous 12 years. This finding did not have a crosscutting aspect because the most significant contributor did not reflect current licensee performance. not reflect current licensee performance.
