Title | Failure to ensure rolling fire doors would automatically close |
Description | An NRC-identified NCV of Farley Nuclear Plant, Unit 1, Operating License Condition 2.C.(4), and Unit 2, Operating License Condition 2.C.(6), Fire Protection, was identified for the licensees failure to install rolling steel fire doors in the Appendix R 3-hour fire barriers between the auxiliary building and new fuel storage area for each of the two units in accordance with the Updated Final Safety Analysis Report (UFSAR). The licensee did not adequately locate fire detectors (fusible links or other type of labeled fire detection devices) associated with these doors to ensure these doors would automatically close under fire conditions. The licensee entered this violation in their corrective action program as condition report (CR) 855837. The licensees failure to install the rolling steel fire doors in accordance with the approved UFSAR was a Performance Deficiency (PD). The PD was more than minor because the installed fire doors were associated with the Mitigating Systems cornerstone attribute of Protection Against External Factors (i.e., fire) and adversely affected the cornerstone objective in that the fire doors would not automatically close which could allow a fire in one area to propagate to an adjacent area. The significance of this finding was determined to be of very low safety significance (Green) because the affected fire zones contain no unique potential damage targets necessary for safe shutdown or other plant components whose loss might lead to a demand for safe shutdown (e.g., a plant trip). The cause of this finding was not associated with a cross-cutting area because it is not reflective of current licensee performance. |
