| Title | Failure to Maintain Flow Channeling Gate Closed in Accordance with the Containment Procedure |
| Description | Green. The inspectors identified a Green NCV of Technical Specification (TS) 5.4.1, Procedures, for Entergys failure to implement procedure OAP-007, Containment Entry and Egress. Specifically, workers transiting the inner and outer crane wall sections of containment on May 14, 2017, did not maintain flow channeling gate C secured during Mode 4 to ensure availability of the containment sumps to provide suction for the emergency core cooling system (ECCS). Entergy immediately restored gate C to an acceptable configuration, and generated condition report (CR)-IP3-2017-02737 to address this issue. This performance deficiency was more than minor because it is associated with the configuration control (shutdown equipment lineup) attribute and adversely affected the Mitigating Systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). A detailed risk assessment was conducted and the change in core damage frequency was determined to be 2E-8, therefore, this issue represents a Green finding. The inspectors determined that this finding had a cross-cutting aspect in the area of Problem Identification and Resolution, Resolution, because Entergy did not take effective corrective actions to address issues in a timely manner commensurate with their safety significance. Specifically, the corrective actions from the event for the prior year were ineffective at preventing this occurrence. [P.3] |
