| Title | Inadequate Procedure and Procedural Compliance for 33 Inverter Overhaul |
| Description | The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, because Entergy did not assure that the overhaul of the 33 inverter was prescribed by an appropriate procedure and that the overhaul was performed in accordance with the procedure, which resulted in restoring the safety-related inverter to service without completing the necessary post-maintenance testing. Specifically, during March 2011, an overhaul of the 33 inverter was performed with an inadequate procedure and a portion of the post-maintenance testing was not performed. This issue was entered into Entergy\'s corrective action program (CAP) as condition reports CR-IP3-2011-03148 and CR-IP3-03432. This finding is more than minor because it is associated with the procedure quality attribute of the Mitigating Systems Cornerstone and adversely affects the objective to ensure the capability of systems that respond to initiating events to prevent undesirable consequences (Le., core damage). Using IMC 0609.04, Phase 1 - Initial Screening and Characterization of Findings, the inspectors determined this finding was of very low safety significance (Green) because the finding was not related to a design or qualification deficiency, did not represent a loss of system safety function, and the finding did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. The finding has a cross-cutting aspect in the area of Human Performance associated with the Work Practices attribute, because Entergy personnel did not ensure that supervisory and management oversight of work activities was adequate. Specifically, the work order for the overhaul of the 33 inverter was issued with inadequate guidance; the work was, in part, performed without using procedures; and a portion of the post-maintenance testing was not performed, as required. |
