DIESEL GENERATOR EXHAUST MANIFOLD FIRE NRC:I Inspector onsite reported that during surveillance, one of four diesel generators unloaded and tripped at 10:53 p.m. October 14, 1976.

Upon investigation an exhaust manifold fire was found and was visible from the Diesel Building exterior.

The local volunteer fire department was called as a precaution but did not enter the site. The fire was extinguished by cooling down the manifold with a fire hose. The fire was caused by carry-over of partially burned fuel into the hot manifold exhaust.
