"Second incident prompts shutdown of nuclear plant after radioactive water leak"

Xcel Energy will temporarily shut down its Monticello nuclear power plant in Minnesota to repair a recurring leak of radioactive water containing tritium, a mildly radioactive form of hydrogen. The leak is fully contained on-site and has not been detected beyond the facility or in any local drinking water. The incident comes after a previous leak of 400,000 gallons of radioactive water in November 2020, which was only made public in March 2021. Xcel Energy is seeking an operating license renewal for Monticello, which is set to expire in September 2030.
