| Title | Failed Backdraft Damper Renders Containment Fan Coil Unit Inoperable |
| Description | A finding of very low safety significance (Green) and an associated Non-Cited Violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, were self-revealed for the licensees failure to maintain adequate procedures for the inspection and verification-of-operation for the A containment fan coil unit backdraft dampers. The licensee entered this issue into the licensees corrective action program as CR 328191; immediate corrective actions were accomplished to repair the affected components. The finding was determined to be more than minor because the finding was associated with the Barrier Integrity Cornerstone attribute of design control and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers, specifically containment, protect the public from radionuclide releases caused by accidents or events. The inspectors determined the finding could be evaluated using the SDP and screened the finding as having very low safety significance (Green). This finding has a cross-cutting aspect in the area of problem identification and resolution, operating experience, because the licensee did not use operating experience to support plant safety |
