Dominion Millstone 3 returning to service

It appears that the Dominion (NYSE:D) Millstone 3 nuclear unit in Connecticut is returning to service.

The unit was listed at 16% generation in the daily reactor status report issued by the Nuclear Regulatory Commission (NRC) early Jan. 29. Unit 3 synched to the grid at approximately 8 a.m., said a company spokesperson.

The unit experienced an unplanned outage shortly before 2 a.m. on Monday, Jan. 25 when one of the reactor coolant pumps at Millstone Unit 3 automatically shut down. The unit has four pumps that circulate water over the fuel in the reactor.  Automatic systems shut down the reactor when the pump stopped operating.

At more than 1,200 MW, Millstone 3 is the larger of the two pressurized water reactors (PWRs) at the Millstone nuclear station in Waterford, Connecticut.
