The Millstone Nuclear Power Station is the only nuclear power generation site in Connecticut 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.
Following a Time magazine cover story on safety issues at Millstone, all three units were shut down. Units two and three were restarted and are still operating at a combined output rating of 2020 electrical megawatts, or MWe; unit one did not restart, permanently ceasing operations in July 1998.
The Millstone site covers about 500 acres (2 km²). The power generation complex was built by a consortium of utilities, using Niantic Bay (which is connected to Long Island Sound and the Atlantic Ocean) as a source of coolant water.
Since opening in the 1970s, the plant has had numerous safety-related shutdowns and at times been placed on enhanced examination status by the Nuclear Regulatory Commission.
In 1999 Northeast Utilities, the plant's operator at the time, agreed to pay $10 million USD 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.
Millstone Units 2 and 3, both pressurized water reactors (one from Westinghouse and one from Combustion Engineering), were sold to Dominon Resources by Northeast Utilities in 2000 and continue to operate.
