| Title | High Energy Line Break Door Missing Lower Support |
| Description | The inspectors identified an NCV of very low safety significance of 10 CFR 50, Appendix B, Criterion III, Design Control, because Entergy personnel did not maintain a high energy line break (HELB) barrier. Specifically, HELB door 76 FDR-DG-272-11, located between the A division emergency diesel generator (EDG) switchgear room and the turbine building was in use as a HELB barrier but was not qualified due to a missing support. The issue was entered into Entergys corrective program as condition report (CR)-JAF-2009-01895. Corrective actions included installing a lower bottom right side support to enable the door to be qualified for HELB. This finding is greater than minor because it is associated with the design control attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, Entergys engineering calculation previously documented that the door could not be qualified with a missing lower support. The inspectors evaluated the significance of this finding using IMC 0609.04, Phase 1 Initial Screening and Characterization of Findings. The finding was determined to be of very low safety significance (Green) because the finding was a qualification deficiency confirmed not to result in loss of operability. The inspectors determined that this finding has a cross-cutting aspect in the area of human performance within the work practices component because Entergy personnel did not ensure that the secondary HELB barrier was qualified as a result of ineffective error prevention techniques.
