(La Crosse, WI) — The Nuclear Regulatory Commission says radioactive water that spilled into the Mississippi River in 2017 during the decommissioning of a former nuclear power plant in Wisconsin wasn’t a public health risk. The La Crosse Tribune reports that LaCrosseSolutions spilled 400 gallons of radioactive water during the 85-million-dollar decommissioning of the former Dairyland Power nuclear plant. The commission’s annual inspection of decommissioning operations last month found that the spill was one of three low-level violations at the La Crosse Boiling Water Reactor. The commission didn’t issue any citations. The inspection report says a hose attached to a sump pump siphoned contaminated water out of a tank, with some spilling into a storm sewer that drains into the nearby river.
