Xcel Faces Nuke Waste Problem as Minnesota Votes Against Storage

LCG, May 16, 2003-Minnesotan legislators voted against Xcel Energy Inc.'s request to store additional radioactive waste on site.

The House decided against Xcel 99 to 33.

The Minnesota senate approved extra radioactive fuel storage at Xcel's nuclear power plant in Red Wing. Prairie Island, a 2 reactor plant, provides 1,076 megawatts capacity. Xcel has said that the plant may face being mothballed by 2007 if radioactive waste cannot be stored on site.

Currently Prairie Island is allowed 17 casks to store waste. The plant is seeking permission to increase the number by 12. The casks are constructed from steel, lead, and concrete and require regular monitoring. Such casks are given 20 year licenses.

Xcel has not given up as yet and insists it will continue to discuss the storage problem with legislators. The company has in past years explored other storage options, including locations in states such as Utah. Prairie Island is the only authorized spent fuel rod storage location in Minnesota.
