OAK RIDGE, Tenn. (AP) -- Authorities are searching for the cause of a fire that destroyed most of the contents of a storage building at the Y-12 nuclear weapons plant in Oak Ridge.
The fire occurred around midnight Saturday in a 40-by-80-foot metal building used to store emergency response equipment and supplies, such as protective clothing and portable generators.
The building is not part of the plant's nuclear weapons production area and no hazardous or radioactive materials were stored inside.
Y-12 firefighters extinguished the blaze in a half hour without injuries.
The Department of Energy plant makes uranium parts for every warhead in the U.S. nuclear arsenal. Y-12 also is the country's primary storehouse for bomb-grade uranium.
