The Millstone Nuclear Power Station is the only nuclear power plant in Connecticut[2] and the only multi-unit nuclear plant in New England. It is located at a former quarry (from which it takes its name) in Waterford.
With a total capacity of over 2 GW, the station produces enough electricity to power about 2 million homes.
The operation of the Millstone Power Station supports more than 3,900 jobs, and generates the equivalent of over half the electricity consumed in Connecticut.[3]
The Millstone site covers about 500 acres (2 km2).[4]
The power generation complex was built by a consortium of utilities, using Long Island Sound as a source of secondary side cooling.
Millstone Units 2 and 3, both pressurized water reactors (one from Westinghouse and one from Combustion Engineering), were sold to Dominion Resources by Northeast Utilities in 2000 and continue to operate.[5]
The plant has had numerous safety-related shutdowns and at times been placed on enhanced examination status by the Nuclear Regulatory Commission.[6][7]
In 1999, Northeast Utilities, the plant's operator at the time, agreed to pay $10 million in fines for 25 counts of lying to federal investigators and for having falsified environmental reports.
Its subsidiary, Northeast Nuclear Energy Company, paid an additional $5 million for having made 19 false statements to federal regulators regarding the promotion of unqualified plant operators between 1992 and 1996.[8][9]
On November 28, 2005, after a 22-month application and evaluation process, Millstone was granted a 20-year license extension for both units 2 and 3 by the NRC.[10]
