| Title | Licensee-Identified Violation |
| Description | 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, states in part that activities affecting quality shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, from August 2015 until April 2017, Unit 2 SRV pilot valves did not incorporate precision grinding to remove micro -cracking layer as described in licensee procedure OCM -VSR509 , Main Steam Relief Valves Target Rock Model 7567 Air Operators and Pilot Assembly, Disassembly , Inspection, and Reassembly. This resulted in 3 of the 11 SRVs being out of tolerance. Since less than 10 SRVs were operable, Unit 2 operation was prohibited by TS 3.4.3. The licensee took corrective action to replace all of the pilot valves with the correct surface finish. This violation was determined to be of very low safety significance (Green) because the violation did not represent a loss of safety function since this condition was supported by the Brunswick Unit 2 Cycle 22 Reload Safe ty Analysis. Specifically, the analysis concluded that with at least five total SRVs operable, the overpressure safety function would not be challenged. The licensee entered this issue into their CAP as CR 2129416. |
