| Title | HELB Barrier Doors Left Open and Unattended |
| Description | The inspectors identified an NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, because Entergy personnel did not maintain an adequate high energy line break (HELB) barrier. Specifically, the inspectors identified that the HELB barrier doors between the turbine building (TB) and A emergency diesel generator (EDG) switchgear room were open when required to be closed. The issue was entered into Entergys corrective action program (CAP) as condition report (CR)-JAF- 2009-02514. Entergy personnel restored the HELB barrier and provided training for operations, maintenance and supervisor personnel on proper work practices. This finding is more than minor because it is associated with the equipment performance attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the reliability of systems that respond to initiating events to prevent undesirable consequences. Specifically, during the timeframe that the HELB doors remained open, the reliability of the A EDG subsystem to perform its safety function would be challenged during a HELB event. 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 it was not a design or qualification deficiency; did not represent a loss of system safety function; and did not screen as potentially risk-significant due to external initiating events. The inspectors determined that this finding had a cross-cutting aspect in the area of human performance because Entergy supervision allowed the HELB barriers to be breached which was inconsistent with the work instructions.
