Page 1 of 1 Docket No. 50-338 Report No. LER 79-147/03L-0 Description of ? vent On October 26, 1979, with the unit in Mode 6, fifteen fire hose stations in the Auxiliary Building were removed from service for more than I hour.

This event is contrary to T.S. 3.7.14.5 and reportable pursuant to T.S. 6.9.1.9.b.

Immediate Corrective Action Fire hoses of equivalent capacity were routed into the Auxiliary Building to provide coverage for the unprotected areas and the fire hose stations were promptly returned to service af ter the required modification had been completed.

Scheduled Corrective Action No scheduled corrective action is required.

Actions Taken to Prevent Recurrence No further actions tre required.
