Millstone Nuclear Power Plant
From Wikipedia, the free encyclopedia
Millstone Nuclear Power Station units 2 and 3 are located at a former quarry in Waterford, Connecticut. The site covers about 500 acres (2 km²). The Millstone complex was built by a consortium of utilities. Both units use Niantic Bay (which is connected to the Long Island Sound and Atlantic Ocean) as a source of coolant water.
Millstone 1 was a General Electric boiling water reactor shut down in November 1995 before being permanently closed in July 1998.
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.
Millstone 2 is a Combustion Engineering plant built in the 1970's, and has a maximum power output of 2700 MWth. 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, it installed a new pressurizer.
Millstone 3 is a Westinghouse plant that started operating in 1986, and has a maximum power output of 3411 MWth.
Millstone was placed on the NRC Watchlist in 1996, when it was revealed that employees who had raised nuclear safety issues had been retaliated against by members of plant management [1] [2]. The three reactors remained shutdown for over one year until both technical and safety culture issues were addressed.
