Description of Event

On October 27, 1980, fire doors S71-7, S71-17, and S71-19 were discovered not functional in accordance with Technical Specification-3.7.15 due to their inability to fully close and latch when allowed to swing freely from a full-open position. Fire door S71-7 is the entrance to the Auxiliary Building from the clean change area and fire doors S71-17 and.19 are the entrance to the IJ and 1H' Emergency Diesel Generator Rooms respectively..This event is reportable pursuant to T.S. 6.9.1.9.b.

Probable Consequences of Occurrence

^

The functional integrity of these penetration fire barriers ensures that fires.will be confined or adequately retarded from spreading to adjacent portions of the facility.

Because a fire watch was established adjacent-to each of the non-functional fire doors, the health and safety I

of the general public were not affected.

gyuse of Event Heavy-use of the fire doors for personnel access caused the associated door hardware to fail preventing proper door operation.

Immediate Corrective Action

4 A fire watch was posted at each of the non-functional fire doors and the doors were temporarily repaired by adjusting the necessary-ha rdwa re~.

i Scheduled Corrective' Action

.Both doors of S71-7 and all hardware except for the coordinator will be replaced. The lock for S71-17 will be adjusted and the closer for the door will be ' replaced. For door. S71-19, the hinges, closer, and mortise will all be replaced.

Actions Taken to Prevent Recurrence t

New designs specific to each door's particular application are being investigated.

l Generic Implications i

There are no generic implications.
