| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1.a requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A. Regulatory Guide 1.33, Revision 2, Appendix A, Item 3.d, requires, in part, procedures for the emergency core cooling system. Procedure SOP-202A, Safety Injection Accumulators, Revision 15, provides the steps to operate the safety injection accumulators. Step 5.2.C required, in part, to unlock and close the accumulator injection valve breakers for Unit 1. Contrary to the above, on July 11, 2011, a non-licensed operator failed to unlock and close the accumulator injection valve breakers for Unit 1. The non-licensed operator unlocked and closed the breakers for Unit 2. The licensee documented the issue in Condition Report CR-2011-007783. Since the accumulator isolation valves for Unit 2 remained open, there was not a loss of safety function of the accumulators and the issue was determined to be of very low safety significance. This non-cited violation addresses the enforcement aspect of the licensee event report documented in Section 4OA3.2. |
