Fire Brigade Drill During this inspection, the inspector witnessed an unannounced fire drill.
The drill scenario was a fire in the diesel generator building and a loss-of-off-site power causing activation of the Units I and 2 Diesel Generators.
It was also reported that the B Diesel had failed to activate properly and that the auxiliary unit operator has been dispatched to the area.
Ten fire brigade members responded to the fire.
The brigade members assembled adjacent to the diesel generator building in full protective firefighting turnout clothing and 'elf
I
contained breathing apparatus.
An initial size up of the fire was made by the Incident Commander.
Three hose lines and two CO systems were used.
The fire was placed under control in 24 mi(utes.
The fire brigade utilized proper manual firefighting methods and reacted to the drill scenario in an effective and efficient manner.
f.
Plant Tour and Inspection of Fire Protection Equipment (1)
The inspector performed an inspection of the fire brigade equipment consisting of fire hoses, tools, self contained
'reathing apparatus and miscellaneous equipment stored at the Units I and 2 turbine building on elevations 557 and 565 elevation of the reactor building.
A total of ten sets of turnout gear, coats, boots, helmets, self contained breathing appartus, one hundred feet of 2-1/2 inch and l-l/2 inch hoses and emergency lights are stored in the 575 elevation of the turbine building.
Four sets of turnout gear, coats, boots, helmets, gloves, emergency lights and one hundred feet of 2-1/2 inch and 1-1/2 inch hoses are stored in the 565 elevation of the reactor building.
