Operators of a nuclear plant in Ohio say they've discovered and contained a pinhole-size leak spraying radioactive coolant at the plant.
Nuclear regulators and plant operators say the leaking coolant at the Davis-Besse nuclear plant near Toledo never got outside the building and posed no threat to the public.
Workers discovered the leak Wednesday as they were getting ready to restart the plant after a month-long maintenance shut down.
A spokeswoman for the plant operated by a subsidiary of FirstEnergy Corp. says they don't know how much coolant spilled out, but it was contained by its collection system.
The plant was last shut down in the fall while its reactor head was replaced. Crews found cracks in an outer concrete wall but the plant was allowed to restart.
