COLUMBIA, S.C. (AP) -- Federal regulators are increasing oversight at a South Carolina nuclear power plant after a leak forced the shutdown of one of the facility's three reactors.
The U.S. Nuclear Regulatory Commission said Wednesday the stepped up monitoring comes with a citation to Duke Energy for failing to identify and correct a crack in a safety system at the Oconee Nuclear Station.
Last November's shutdown at the plant near Seneca, about 30 miles west of Greenville came after engineers detected flaws in the airtight, steel-lined concrete containment building designed to prevent radiation from leaking into the air or ground.
Officials said there was no threat to employees or the public, and the crack was quickly repaired.
A Duke spokeswoman did not immediately return a message seeking comment.
