| Title | Failure to Identify Embedded Operator Challenge |
| Description | Inspectors identified a finding of very low safety significance associated with the licensees failure to identify an embedded operator challenge. Specifically, the licensee proceduralized compensatory actions which were necessary in order to maintain a negative pressure (-0.25 in. H2O) inside the fuel building when opening the inner railroad
bay door. The licensee documented this issue in the CAP as IR 1589104 and subsequently screened this issue as an operator challenge. The inspectors determined that the licensees failure to identify an embedded operator challenge was a performance deficiency. This finding was more than minor significance because it was associated with the Barrier Integrity Cornerstone attribute of structure, system and component (SSC) and barrier performance, and adversely affected the cornerstone objective to provide reasonable assurance that the physical design barrier of secondary containment protects the public from radionuclide releases caused by accidents or events. This finding is of very low safety significance due to answering no to all questions under the Barrier Integrity Cornerstone column of IMC 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings. The inspectors concluded that this finding affected the cross-cutting aspect of problem identification and resolution. Specifically, the licensee failed to implement its CAP with a low threshold for identifying issues and did not identify this challenge to operators completely, accurately, and in a timely manner commensurate with its safety significance. |
