The Millstone Nuclear Power Plant 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.
Although located in Waterford, Millstone is most clearly seen from downtown Niantic. It is visible from the Niantic Boardwalk area and from the Niantic River Bridge, and is also visible to Amtrak customers on the NEC line which as it skirts Niantic Bay.
Millstone earned OSHA's top award for workplace safety in October 14, 2004, and earned the Top Industry Practice/ Framatone ANP Vendor Award for its work developing novel ultrasonic leak inspection techniques in March 2001.
Millstone Nuclear Power Plant Units 2 and 3, both pressurized water reactors (one from Westinghouse and one from Combustion Engineering), were sold to Dominion by Northeast Utilities in 2000 and continue to operate.
On November 28, 2005, after a 22-month application and evaluation process, Millstone was granted a 20-year license extension to both units 2 and 3 by the NRC.
Millstone Nuclear Power Plant Unit 1 was a General Electric boiling water reactor, producing 660 MWe, shut down in November 1995 before being permanently closed in July 1998.
Millstone Nuclear Power Plant Unit 2 is a Combustion Engineering plant built in the 1970s, and has a maximum power output of 2700 MWth (870 MWe). It has 2 steam generators, and 4 reactor cooling pumps (RCP). It is currently undergoing an upgrade to its safe shutdown system which already met NRC standards. During its refueling outage in October 2006, the operator installed a new pressurizer.
Millstone Nuclear Power Plant Unit 3 is a Westinghouse plant that started operating in 1986, and has a maximum power output of 3411 MWth (1150 MWe). Recently, the NRC approved a power uprate for Unit 3 that will increase its electrical output 7.006% to 3650 MWth (1230 MWe. The increase will take effect by the end of 2008.
