On February 26, 2004, AREVA shipped two replacement steam generators to the United States for Xcel Energy's Prairie Island Nuclear Generating Plant located in Minnesota and operated by Nuclear Management Company.
The steam generators were manufactured at the Chalon Saint Marcel plant in the Saône et Loire region of France and will be transported by river and sea before being installed in Prairie Island Unit 1 this fall.
This delivery is the first by AREVA to a customer in the United States. Xcel Energy authorized engineering design work on the replacement steam generators in August 2000.
Through its manufacturing plant in Chalon, France, AREVA has become the leader in the replacement equipment market. The group has a 40 percent share in the steam generator market and a 50 percent share in the reactor vessel head replacement market (overall value of around 350 million euro). At the end of 2003, the American market represented around 60 percent of the workload at the Chalon Saint Marcel plant.
In 2002, the United States generated 1.7 billion euro in revenues for AREVA including 1.1 billion in the nuclear field, representing a two-fold increase in our market shares since 2000. Growth continued in the nuclear field in 2003 generating revenues of 1.3 billion euro (16 percent increase).
The two Prairie Island pressurized water reactors have been in commercial operation since December 1973 and 1974 respectively and have an overall production capacity of 1,060 MW.
* A steam generator is a heat exchanger which weighs about 400 tones and is over 20 meters high. It transfers calories from the water in the primary system to water in the secondary system. It transforms this water into steam to power a turbine which in turn drives an alternator to generate electricity. Like reactor vessel heads, steam generators are replaced to extend the reactor’s service life.
