The company that owns a nuclear power plant northwest of Minneapolis said Thursday that water containing a radioactive material is leaking from the plant for a second time, but there is no danger to the public and the facility will power down Friday to begin working on permanent repairs.
The announcement by Xcel Energy comes about a week after Minnesota regulators announced that 400,000 gallons (1.5 million liters) of water containing tritium had leaked from the Monticello Nuclear Generating Plant back in November.
