| Title | Improper Orientation of Fire Dampers in Auxiliary Building |
| Description | An NRC-identified Green non-cited violation of Sequoyah Operating License Conditions 2.C.(16) and 2.C.(13) for Units 1 and 2 respectively, was identified for the licensees failure to ensure that fire dampers were functional, as required by the approved fire protection program (FPP), in the Auxiliary Control Room (fire area FAA- 066), Vital Battery Board Room II (fire area FAA-068), and Vital Battery Board Room III (fire area FAA-087) fire area boundaries. The licensee entered this issue into the corrective action program as Problem Evaluation Reports 845913 and 848580, and implemented hourly roving fire watches in the affected fire areas. The licensees failure to ensure the fire dampers were functional as required by the FPP was determined to be a performance deficiency. This performance deficiency was more than minor because it affected the reactor safety mitigating systems cornerstone attribute of protection against external factors (i.e., fire) and it affected the fire protection defense in depth strategies involving the control of fires that do occur and to protect systems important to safety. The finding was screened in accordance with NRC IMC 0609, Significance Determination Process, Attachment 4, Initial Characterization of Findings, which determined that an IMC 0609, Appendix F, Fire Protection Significance Determination Process, review was required as the finding involved the ability to confine a fire. The finding category of Fire Confinement was assigned, based upon that element of the FPP being impacted. Using IMC 0609, Appendix F, Attachment 1, Fire Protection Significance Determination Process Worksheet, the inspectors determined that the finding was of very low safety significance (Green) at Task 1.4.3, Question C, based upon observation that a fully functional automatic sprinkler system was on either side of each affected fire barrier partition. No cross cutting was assigned to this finding because the cause of the finding was not indicative of current licensee performance. The dampers were purchased and installed in 1997. |
