| Title | Failure to Install Fiber Reinforced Polymer on Unit 1 Auxiliary Building Wall as required by Procedure |
| Description | An NRC-identified Non-Cited Violation (NCV) of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, was identified for the licensees failure to install Fiber Reinforced Polymer (FRP) on the Unit 1 Auxiliary Building wall in accordance with the installation procedure. The licensee had not identified and repaired all wall defects greater than 0.75 inches deep as required by Procedure TN/1/A/102145/01C, FRP Installation. The issue was entered into the licensees corrective action program as PIP O-10-7414. The inspectors determined that the licensees failure to follow the approved procedure for FRP installation was a performance deficiency. The performance deficiency was more than minor because it was associated with the external events attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective in that continued failure to identify wall defects could result in the FRP failing to provide the required reinforcing for protection against the differential pressures generated by on-site tornados. The inspectors determined the finding to be of very low safety significance (Green) because the licensees structural analysis determined that the overall structural integrity of the wall would not be affected. This finding had a cross-cutting aspect of taking corrective actions to address safety issues and adverse trends in a timely manner commensurate with their safety significance and complexity in the Corrective Action Program component of the Problem Identification and Resolution area in that corrective actions for a previously identified adverse trend of not following procedures were ineffective.
