Ameren Mo. Callaway reactor shut
NEW YORK, Oct 13 (Reuters) - Ameren Corp's (AEE.N) 1,190-megawatt Callaway reactor in Missouri shut by early Monday, the U.S. Nuclear Regulatory Commission said in a report.
The unit was operating at full power.
Electricity traders guessed the unit shut for a planned month-long refueling and maintenance outage expected to start in mid October.
The unit last shut from April 2-May 11, 2007. It is on an 18-month refueling cycle.
The Callaway station, which entered service in 1984, is located near Fulton in Callaway County, about 110 miles west of St Louis.
One MW powers about 700 homes in Missouri.
In July, Ameren filed with the NRC for permission to build one of Areva SA's (CEPFi.PA) 1,600 MW Evolutionary Power Reactors (EPR) at the site.
Using an industry estimate of $4,000 per kilowatt, the new reactor could cost about $6.4 billion. Other nuclear operators considering the EPR however have estimated total costs as high as $10 billion.
Ameren, of St. Louis, owns and operates more than 14,000 MW of generating capacity, markets energy commodities, and transmits and distributes electricity (2.4 million customers) and natural gas (1 million) to customers in Illinois and Missouri.
