\r\n \r\n 37-year old nuclear reactor, Unit 2 of The Milestone Nuclear Power Station in Connecticut, was shut down on Sunday, August 12, 2012 as seawater used in cooling the reactor soared to 76.7 degrees Fahrenheit (24.83 degrees Celsius).880-megawatt reactor was shut down by Dominion Power who operates the facility. Under the reactor�s safety rules, the cooling water can be no higher than 75 degrees Fahrenheit.
\n
\n�Temperatures this summer are the warmest we�ve had since operations began here at Millstone,�� said a spokesman for Dominion, Ken Holt.
\n
\nUnit 2 of Millstone Power Station has occasionally shut for maintenance or other issues, but in its history it has never gone down because of excessively warm water, Holt said on Monday. Dominion does not have an estimate of when the unit will restart, he added.
\n
\nThe plant�s first reactor, now retired, began operation in 1970. The plant�s third reactor was still running on Monday, but engineers were watching temperature trends carefully out of concern that it, too, might have to shut down.
\n
\nThe water from the sound is piped into the plant to absorb heat from pumps and other pieces of equipment. As the sound�s temperature inched upward this summer, Dominion Power received permission from the Nuclear Regulatory Commission to measure it at three locations instead of one and to calculate the average in the hope that it would be lower. That did not help on Sunday.
\n
\nAnd higher water temperatures could lie ahead. The sound�s temperature usually does not peak until late August.
\n
\nEventually, engineers could change reactor�s intake pipe so it draws water from further below the surface, where temperatures are lower, Mr. Holt said. They could also sharpen their pencils and try to determine whether the plant can operate safely with cooling water above 75 degrees, but neither is a short-term project.
\n
\nThe Millstone Nuclear Power Station is the only nuclear power generation site in Connecticut. It is located at a former quarry (from which it takes its name) in Waterford. Of the three reactors built here, units two and three are still operating at a combined output rating of 2020 MWe.
