"US Nuclear Plant Leaks 400,000 Gallons of Radioactive Water Without Public Notice"

A leak of 400,000 gallons of radioactive water containing tritium from Xcel Energy’s Monticello nuclear power plant in Minnesota occurred in November 2020, but public officials only confirmed it publicly in March 2021. The leak came from a water pipe running between two buildings and has not been detected beyond the facility or in any local drinking water, according to the energy company. The Nuclear Regulatory Commission and the state of Minnesota were notified by Xcel Energy on the same day the presence of a leak was confirmed. The company said the water contains levels of tritium below NRC safety thresholds and poses no health and safety risk to the local community or the environment.
