| Title | Failure to Follow Procedure During Removal from Service of Emergency Diesel Generator Ventilation |
| Description | The inspectors identified a self-revealing NCV of TS 5.4, Procedures, because Entergy personnel did not adequately implement procedures when removing the ventilation system for the A emergency diesel generator (EDG) subsystem from service. Specifically, operators did not implement tagout placement instructions, which required that the affected EDGs be declared inoperable once the ventilation system was tagged out. Additionally, control room operators did not respond to the resultant A EDG ventilation system common alarm in accordance with the alarm response procedure, which also would have led to the EDGs being declared inoperable. As a result, TS 3.8.1 was not entered in a timely manner and the TS surveillance requirement was not performed within the specified completion time. As immediate corrective action, the A EDG subsystem was declared inoperable and the specified surveillance requirement was completed. The issue was entered into the CAP as CR-JAF-2012-02591. The finding was more than minor because it affected the equipment performance attribute of the Mitigating Systems cornerstone objective to ensure the availability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the offsite electrical circuits were not verified available by operators for approximately three hours while the A EDG subsystem was inoperable. The inspectors evaluated the finding using the Phase 1, Initial Screening and Characterization of Findings, worksheet in Attachment 4 to IMC 0609, Significance Determination Process. The inspectors determined this finding was not a design qualification deficiency resulting in a loss of functionality or operability, did not represent an actual loss of safety function of a system or train of equipment, and was not potentially risk significant due to external initiating events. Therefore, the inspectors determined the finding to be of very low safety significance. This finding has a cross-cutting aspect in the area of Human Performance, Work Practices, because operators did not follow procedures. |
