| Title | Steam Exclusion Door Failure Results in Multiple Safety Systems Being Declared Inoperable |
| Description | A finding of very low safety significance (Green) and associated NCV of10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was self-revealed for the licensees failure to follow the corrective action program procedure to implement corrective actions that could have prevented a December 30, 2008, door seal failure, which rendered both trains of control room ventilation inoperable. The licensee entered this issue into its corrective action program and, as partially corrective action, has increased its monitoring of doors for potential failure mechanisms. The finding was determined to be more than minor because it was associated with the Barrier Integrity Cornerstone attribute of Configuration Control and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. The inspectors evaluated the finding using the Significance Determination Process (SDP) in accordance with Inspection Manual Chapter (IMC) 0609, Significance Determination Process, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Findings, dated January 10, 2008, and determined the finding represented a degradation of the barrier function to protect against radiological hazards, toxic gas, and smoke that required a Phase 3 analysis. A Region III Senior Reactor Analyst completed a qualitative Phase 3 analysis and determined that because the duration of the event was small, 44 minutes, the issue screened as having very low safety significance(Green). The inspectors determined that the finding had a cross-cutting aspect in the corrective action program component element of problem identification and resolution because the licensee failed to take appropriate corrective actions to address safety issues and adverse trends in a timely manner.
