MONTICELLO, Minn. – A second leak at the Monticello nuclear plant has been fixed, and the plant will be on line again next week, the energy company Xcel announced. The company powered down the plant after radioactive tritium was found leaking into groundwater. The power-down was necessary to catch the tritium-contaminated water from a larger leak in November, said Xcel spokesperson Theo Keith. The 647-megawatt nuclear station will be shut down again in April, for previously scheduled refueling, Keith said.
