| Title | Failure to Monitor Forebay Structure |
| Description | The inspectors identified a finding of very low safety significance and associated NCV of Facility Operating Licenses DPR58 condition 1.D for Unit 1 and DPR74 condition 1.D for Unit 2. Specifically, the licensee failed to perform structural monitoring of the Service Water Screen House as stipulated in their renewed license. The inspectors identified that the licensee had not conducted inspections of the forebay area west of the traveling screens as required by their license. Since the licensees inspections of portions of the submerged screenhouse structure showed the structure remained in an acceptable condition, no immediate safety concern exists. The licensee has entered the condition into the Corrective Action Program (CAP) and developed plans to inspect. The licensees failure to perform inspections of the Service Water Screen House was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using IMC 0609, Appendix A, issued June 19, 2012, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, the inspectors determined the finding screened as green using question A.1 because the deficiency did not render the structure inoperable. The performance deficiency had a cross-cutting aspect of Change Management, (H.3) in the human performance area. Specifically, licensee personnel did not implement the revised license with nuclear safety as the overriding priority. |
