HARTFORD, Conn., Nov. 4, 2015 /PRNewswire/ -- Dominion Generation 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.
