Crack forces shutdown of North Carolina nuclear reactor

A quarter-inch crack in a reactor sensor at the Shearon Harris nuclear plant in southwest Wake County has forced Duke Energy to take the plant offline, officials said Thursday.

No radioactive material leaked from the plant, and public health and safety is not in danger, spokeswoman Kim Crawford said.

"There are no indications that there was any leakage," Crawford said. "We made the conservative decision to take the unit offline and make the repair."

Crawford said she couldn't say how long the reactor would be out of commission, but she said the utility has plenty of capacity and wouldn't need to purchase electricity from outside sources to meet demand.

"We're not anticipating any issues," she said. "While our plant is offline, we'll continue to serve our customers."

Shearon Harris provides power to about 550,000 customers, and industry sources said not operating the reactor could cost Duke about $1 million a day. Read more >>
