| Title | Licensee-Identified Violation |
| Description | Title 10 of the Code of Federal Regulation Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, the licensee failed to provide adequate work instructions to place the high pressure safety injection valve, 2CV-5035-1, in a condition to support effective motor-operated valve contact burnishing. Specifically, the licensee failed to properly burnish the closed contacts for motor-operated valve 2CV-5035-1 during a preventative maintenance activity. The valve subsequently failed to fully close during a surveillance test. The inspectors determined this finding to be of very low safety significance, Green, because it: 1) is not a design or qualification deficiency that resulted in loss of operability or functionality; 2) did not represent an actual loss of safety function of a system or train; 3) did not result in the actual loss of one or more trains of non-technical specification equipment designated as risk significant by 10 CFR 50.65 for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />; and 4) did not screen as potentially more risk significant due to a seismic, flooding, or severe weather initiating event. This issue was entered into the corrective action program as CR-ANO-2-2011-1329. |
