| Title | Fuel Pool Radiation Monitor Corrective Actions |
| Description | The inspectors identified a finding of very low safety significance (Green) and associated Non-Cited Violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for two examples of the failure to follow procedures associated to the troubleshooting and repair of RIS4131A Refuel Floor Exhaust Radiation Monitor. The licensee initiated WO 40190702-01, RIS4131A Refuel Floor Exhaust Rad Mon Upscale and Group 3, to troubleshoot and repair the power supplies. The licensee was still evaluating planned corrective actions for the failure to follow the work order instructions. The performance deficiency was determined to be more than minor because it was associated with the Barrier Integrity Cornerstone attribute of providing reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect the public from radionuclide releases caused by accidents or events. Specifically, RIS4131A failing to operate in conjunction with a single additional failure (RIS4131B) could allow the release of radioactive contamination due to preventing an automatic secondary containment isolation (Group 3). The finding screened as having very low safety significance (Green) because the inspectors answered Yes to question C.1 of IMC 0609, Appendix A, Exhibit 3. The inspectors determined that the contributing cause that provided the most insight into the performance deficiency was associated with the cross-cutting aspect of Human Performance, having Work Control components that support long-term equipment reliability by performing maintenance that is more preventive than reactive. |
