Dear Mr. Davis:
This special report is being submitted in accordance with Technical Specification 3.7.10 Action a, to inform you that the following eight fire barriers have been inoperable longer than the seven days allowed by Technical Specification 3.7.10.
Fire barrier penetration seal
- F6185, separating the Unit One control room and the Unit One control room cable
- vault, was declared inoperable on August 22, 1989 and was restored to operability on August 30, 1989.
A fire
- watch, as required by Technical Specification 3.7.10 Action a, was maintained while the seal was inoperable.
Fire dampers 1-HV-ACF-Dl and 1-HV-ACF-D2, in the Unit One P-250 computer room; and fire dampers 2-HV-ACF-Dl and 2-HV-ACF-D2, in the Unit Two P-250 computer room
,were declared inoperable on August, 21,. 1989 due to a failure of the fire damper release mechanism associated with each damper.
At that time, a 'roving fire watch, as required by Technical Specification 3.7.10 Action a was established for the affected fire zones.
This roving patrol will remain in effect until the problem is resolved.
An engineering analysis/evaluation is being performed to determine whether a reconfiguration of the fire damper release mechanisms is necessary.
We will inform you through a follow-up report when the engineering analysis/evaluation has been completed and the dampers have been restored to operability.
