MONTICELLO, Minn. – The giant energy company Xcel failed to report a leak of radioactive water to the public at its Monticello nuclear plant in November, ostensibly to avoid public panic. The leak, of 400,000 gallons, was, however, reported to state and federal authorities. These agencies remained mum until word leaked out Thursday — 3-1/2 months later. Participating in the public  silence:

> Minnesota Pollution Control Agency.

> Minnesota Department of Health.

> Minnesota Department of Natural Resources.

> Federal Nuclear Regulatory Commission.

.When confronted, the agencies said that Xcel  took swift action to contain the leak and that the  agencies have been monitoring  clean-up. There is no risk to the local community or the environment, the agencies said. Te plant is 50 years old. It has 670 employees.

On Mississippi River. The riverside plant is 40 miles upstream from Minneapolis and 150 miles upstream from Winona.
