The inspectors identified deficiencies regarding Entergys execution of corrective actions documented in the
RCEs, as well as understanding of some of the causes of the issues. Specifically, inspectors identified several examples in the
RCEs where corrective actions were not completed as intended or were closed prematurely. Additionally, for one of the
RCEs, inspectors determined that Entergy failed to investigate a deficient condition sufficiently to ensure they fully understood all of the causes of the event. Inspectors determined that the specific deficiencies in execution of
CAP procedures discussed in the findings in sections 02.02.e.1 and 02.03.f.1 of this report were indicative of the
CAP implementation weakness that Entergy identified as part of their common cause and safety culture evaluations. Correspondingly, inspectors determined that corrective actions specified in the common cause and safety culture evaluations were not effective at ensuring that all the causes of the performance issues were understood and that corrective actions taken were adequate to address the identified root and contributing causes. Taken collectively, the issues associated with the two White
PIs represent a significant weakness, as discussed in
IP 95002.
