Worker killed in accident at Russellville, Arkansas nuclear plant

RUSSELLVILLE, Ark. (AP) - Entergy Arkansas says a worker was killed and three others injured when a heavy piece of equipment fell at a nuclear plant.

The utility says the public is not a risk after the industrial accident Sunday morning at its Arkansas Nuclear One plant in Russellville, about 70 miles northwest of Little Rock.

Entergy says the workers were moving the equipment from the plant's turbine building.

Entergy and the Arkansas Department of Health say the accident did not affect the plant's reactors. They also say radiation wasn't involved.

The reactors have been shut down, and the company says they are stable....

Nothing at all about structural damage, but if it was the generator it is unlikely to have impacted the reactor or its building.
