| Title | Failure to Maintain Flow Channeling Gates Closed in Accordance with the Containment Procedure |
| Description | 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 failed to maintain at least one (of two) flow channeling gate closed to ensure availability of the containment sumps to provide suction for the ECCS. Entergy immediately coached the gate monitor and restored the gates to an acceptable position. Entergy generated CR-IP2-2016-04036 to address this issue. This performance deficiency is more than minor because it was associated with the configuration control (shutdown equipment lineup) attribute of the Mitigating Systems cornerstone and affected the 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 determined that the change in core damage frequency was determined to be 7E-9, therefore, this issue represents a Green finding. This finding had a cross-cutting aspect in the area of Human Performance, Avoid Complacency, because Entergy did not consider potential undesired consequences of actions before performing work and implement appropriate error-reduction tools. Specifically, the work crew did not understand the requirements and potential consequences prior to commencing work and the gate monitor did not enforce these requirements to maintain at least one gate locked or pinned closed as required by OAP-007.
