Xcel to temporarily shut down Monticello plant amid new tritium leak

Xcel Energy says it will power down its Monticello nuclear power plant after monitoring equipment on Wednesday detected more radioactive tritium was leaking into groundwater.

Crews discovered a container being used to catch the contaminated water as a short-term solution had spilled over, resulting in a new leakage from the same location, Chris Clark, president of Xcel's operations in Minnesota and the Dakotas, told reporters Friday morning in Monticello.
