Fire briefly triggers emergency at South Carolina lab on former nuclear weapons site

A fire at a national lab in South Carolina that is in a complex where key parts for nuclear bombs were once made, triggered an emergency declaration Wednesday that shut down incoming traffic and restricted air and rail service in the area.

The fire at the Savannah River National Laboratory on the U.S. Department of Energy’s Savannah River Site was extinguished by Wednesday night and the site returned to normal operations.

No detectable levels of contamination were found, according to a Savannah River Site statement.

The site was opened in the early 1950s as the Cold War was heating up. Today it is used for environmental stewardship and cleanup, along with nuclear waste management and disposition of nuclear materials, according to the U.S. Department of Energy.

The lab currently does experiments with nuclear materials and also does processing work with radioactive material, including operating a facility for radioisotope recovery from used nuclear fuel, said Edwin Lyman, director of nuclear power safety at the Union…
