Unit 3 is the three special inspections Turbine Driven Auxiliary feedwater pump poor maintenance plant...

I wasn't sure if it was the backup, backup flex DG or the emergency diesel generator. Commonly they have a oil leak and the oily insulation catches fire. It is not a big deal. Not much can catch fire on the engine. This seem much bigger than that. Maybe a breaker explosion or the generator catching fire?
The fire occurred on the Unit 3 diesel generator while it was being tested after a maintenance outage. The fire started about 11 a.m. and went out on its own shortly afterward. Backup diesel generators are used to provide power to the station when normal offsite power is lost.
First report:
Dominion Generation (NYSE: D) declared an Alert at its Millstone Power Station Unit 3 in Waterford, Conn. today.

The company declared an Alert at the station at 11:33 a.m for Unit 3. Federal, state and local officials have been notified. An Alert emergency is the next to least serious of four emergency categories in the Nuclear Regulatory Commission's rating system.

The emergency was declared because of a fire in the Unit 3 backup diesel generator. The fire quickly burned out.

No release of radioactive material has occurred as a result of this event. Minor releases associated with normal plant operations pose no danger to the public or plant workers. These minor releases are below federally approved operating limits, below natural background levels and can not be detected at the site boundary.

Millstone Unit 3 continues to operate normally at 100% power and Millstone Unit 1 remains in its decommissioned state. Unit 2 is in a routine refueling outage.
