| Title | Licensee-Identified Violation |
| Description | As described in Section 4OA2.3 of this report, during routine surveillance testing on February 1, 2009, the Division 1 RHR torus suction isolation valve, E1150F004A, would not stroke properly from the control room. Troubleshooting identified loose wires in the MCC bucket that were the cause of the failure. The licensee secured the loose wires, ensured there were no additional loose wires, completed a stroke test of the valve, and returned it to service the following day. The licensee entered this issue into their CAP as CARD 09-20637 and completed an apparent cause evaluation. The licensee concluded that the wires most likely came loose during previous diagnostic testing post-maintenance activities which did not incorporate steps to ensure that leads disturbed during the test were tight prior to closing out the MCC bucket. The licensee revised the applicable maintenance procedure to include such an inspection. 10 CFR 50,Appendix B, Criterion V requires, in part, that activities affecting quality be properly preplanned and performed in accordance with procedures appropriate to the circumstances. Contrary to the above, licensee procedure 35.306.009 was not appropriate to the circumstances because it did not ensure that potentially disturbed leads were tight and secure following maintenance. The licensee entered this issue into their CAP as CARD 09-20637. This issue screened as Green because there was no loss of safety function |
