A nuclear power plant which is 20 miles south of Raleigh has been shut down after a crack and corrosion was found in the reactor vessel.
Duke Energy owns the Shearon Harris plant, which began operations in 1987.
The Nuclear Regulatory Commission says the quarter inch crack was not all the way through the reactor wall and there's no indication any radioactive material escaped.
The NRC says the plant was shut down so crews could repair the crack. It says there is no impact "to the health and safety of employees or the public."
