Federal officials say an accident that occurred during testing at the Savannah River Plant is another sign that problems at the nuclear facility are out of control.

"The issue is not physical damage. The issue is a lack of formality, a lack of discipline," Richard Starostecki, deputy assistant energy secretary, said Tuesday. "This doesn't give you confidence in their ability to handle anomalies."The Engergy Department and Du Pont Co., the plant's operator, are investigating Sunday's accident. Federal officials said there was no leakage of radiation or other hazardous material.

Du Pont officials said damage has tentatively been estimated at $20,000 and will take only a few days to repair.
