| Title | Untimely Completion of a Corrective Action to Prevent Recurrence |
| Description | A finding of very low safety significance (Green) was identified by the inspectors when licensee personnel failed to follow procedure LS-AA-125-1001, Root Cause Analysis Manual, Attachment 12, in the implementation of corrective actions to prevent recurrence. Specifically, actions taken in response to the Unit 1 reactor trip on August 16, 2010, did not meet the criteria in procedure LS-AA-125-1001, Attachment 12, CAPR Attributes, for being timely, effective, and long-lasting (i.e. not temporary). The licensee entered this issue into the CAP as IR 1395327. The inspectors determined the failure to follow procedure LS-AA-125-1001 was more than minor because it could be reasonably viewed as a precursor to a significant event and, if left uncorrected, had the potential to lead to a more significant safety concern. Specifically, the licensee continued to rely on administrative controls, temporary catch containments, and transferring water slowly to prevent water overflow events rather than through a permanent modification to the standpipes. As a result, the potential for water overflow events, while reduced, would not prevent recurrence. The inspectors determined that the finding was of very low safety significance (Green) because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. This finding had a cross-cutting aspect in the Corrective Action Program component of the Problem Identification and Resolution cross-cutting area P.1(d) since the licensee did not take timely and appropriate corrective actions to prevent recurrence in response to the August 16, 2010, Unit 1 reactor trip. |
