"Radioactive Water Leak at Minnesota Nuclear Plant Goes Unnoticed by Officials"

At least 400,000 gallons of radioactive water leaked from Xcel Energy’s Monticello nuclear power plant in Minnesota in November 2020, but officials only publicly revealed the spill on Thursday. The delay in announcing the leak to the public raised questions about public safety and transparency. However, industry experts said there was never a public health threat as the radioactive water never reached a threshold that would have required public notification. Tritium is a radioactive isotope of hydrogen that occurs naturally in the environment and is a common by-product of nuclear plant operations.
