d.
Drills The inspector witnessed two unannounced fire drills with the licensee's fire protection coordinator. Both drills were conducted on June 13, 1979.
For the first drill, which was held at one o' clock, a wood crate, placed in the open area between the turbine building and the circulating ater pump house was ignited for the fire fighting effort.
Eight i.inutes laspe before brigade members appeared on the scene of the first fire drill.
The shift supervisor appeared on the fire scene within two (2) minutes after ignition of wood crate. Water was not available for eleven minutes after init!al ignition of wood crate. When the water was finally put into service, misalignment of water control valve resulted in low water pressure making it difficult to extinguish fire.
No attempt was made by brigade members to realign water control valve.
The fire was extinguished thirteen minutes after ignition of wood crate. Brigade members were not properly dressed to fight a real fire had there been one.
Response to the second fire drill was much better.
Brigade members were on the scene within two minutes after ignition of wood crate.
However, brigade members appeared on the scene partially clothed in fire protection clothing. Water was turned on within five minutes after ignition of wood crate with sufficient water pressure to provide necessary stream to combat fire.
The fire in the wood crate diminished before brigade members could apply the water.
The Fire Protection Coordinator agreed with the inspector that the fire drills did not meet the objectives of the drill. A critique is to be performed to determine areas of improvement.
This item is unresolved pending NRC review of licensee's evaluation and corrective action.
