| Title | Licensee-Identified Violation |
| Description | 10 CFR 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 requirement, licensee personnel failed to adequately implement Procedure OP-1412.001, \"Preventative Maintenance of Limitorque SB/SMB Motor Operators,\" Revision 18. Specifically, Supplement 2, steps 2.2.6 and 2.2.7 of this procedure directs that, with no thrust load on the actuator, check the fasteners and bolting for tightness. If the component remains closed, then proceed to the next step and record this in the exceptions section. Licensee personnel identified that on July 8, 2008, station maintenance personnel failed to correctly perform these steps which resulted in the unplanned entry into a 72-hour shutdown limiting condition of operation. This was licensee identified because operations personnel identified this issue during review and discussion with maintenance personnel following the performance of the work. In accordance with NRC Manual Chapter 0609, \"Significance Determination Process,\" Phase 1 Worksheet, the finding was determined to have very low safety significance because: (1) the finding was not a qualification deficiency that resulted in a loss functionality of Chiller Valve VCH-4B; (2) it did not lead to an actual loss of safety function of the system or train; (3) it did not result in the loss of one or more trains of nontechnical specification equipment; (4) it did not represent an actual loss of safety function of one or more nontechnical specification trains of equipment designated as risk-significant per 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 />; (5) it did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This issue was entered into the licensee\'s corrective action program as Condition Reports ANO-C-2008-1657 and ANO 2-2008-1761. |
