COVERT TOWNSHIP, Mich. (AP) -- A federal safety official says that 79 gallons of "very slightly radioactive water" from a leaky tank at the Palisades Nuclear Power Plant spilled into Lake Michigan.
Operators of the southwestern Michigan plant shut it down Sunday after discovering a growing leak Saturday in a water storage tank.
The plant is 80 miles east-northeast of Chicago in Van Buren County's Covert Township. It's been under heightened Nuclear Regulatory Commission attention for a series of breakdown over two years.
NRC spokeswoman Viktoria Mitlyng told The Associated Press on Monday that investigators determined that 79 gallons entered a basin holding thousands of gallons of non-radioactive water before entering the lake.
She says there's no human health risk.
The NRC is sending a metallurgy expert to locate the source of the leak.
