Prairie Island Nuclear Power Plant

The Prairie Island Nuclear Power Plant is an electricity-generating facilitiy located in Welch, Minnesota along the Mississippi River. The plant, which first began operating in 1973, has two nuclear reactors (pressurized water reactors) made by Westinghouse that produce a total 1,076 megawatts of power. They are licensed to operate through 2013 and 2014. The plant is owned by Northern States Power Company (NSP), today a subsidiary of Xcel Energy, and is operated by the Nuclear Management Company (NMC). It is one of two active nuclear facilities in Minnesota and has proven to be the most controversial due to the storage of nuclear waste in large steel casks on-site, an area which is a floodplain of the Mississippi.

NSP had initially intended to send radioactive waste to a storage facility operated by the United States federal government, but no such site is yet open for use (the Yucca Mountain facility is under construction, but heavy opposition means that it may not ever open). In 1991, the company requested permission from the Minnesota Public Utilities Commission to eventually store waste in 48 dry casks on the site. Opposition by environmentalists and the local Prairie Island Indian Community led the Minnesota Legislature to decrease the number of allowed casks to 17, enough to keep the plant operating through approximately 2003.

Eventually, those casks filled, and Xcel Energy requested that the limit be expanded beyond 17 casks. The legislature granted the request, but required the company to make greater use of renewable energy such as wind power and to pay the local Indian community up to $2.5 million per year.

In September 2004, Xcel requested that the U.S. Nuclear Regulatory Commission extend the licenses of the reactors beyond 2013/2014. The company has also requested the use of a similar storage system at its Monticello plant, which is currently licensed through 2010.
