The Dominion (NYSE:D) Millstone 2 nuclear unit in Connecticut was back at 100% power early Aug. 16, according to Nuclear Regulatory Commission (NRC) data, after the facility had experienced an unplanned outage a few days earlier.
A pump problem had forced the pressurized water reactor (PWR) located in New London County, Connecticut, offline on Aug. 11.
Operators at Millstone Power Station had removed Unit 2 from service Aug. 11 because two of the unit’s four circulating water pumps automatically shut down, Dominion has said. The circulating water pumps deliver water from Long Island Sound that is used to condense steam back into water as part of normal plant operations.
Millstone Units 2 and 3 have a combined generating capacity of more than 2,100 MW. Unit 3 was not affected by the Unit 2 outage.
