KNOXVILLE, Tenn. – A fire at a Y-12 National Security Complex uranium processing facility in Oak Ridge, Tennessee has been contained, officials from the National Nuclear Security Administration said.

The fire at the Y-12 complex started in a uranium processing area in building 9212 on Wednesday at 9:14 a.m., Y-12 communications manager Taz Painter said in an email to Knox News.

Several hundred employees from building 9212 and others were evacuated. A 12:30 p.m. update from Y-12 stated all evacuated workers were accounted for and no injuries or contaminations were found.

Air monitors did not go off, which means there was no release of radioactive material, officials said. Officials said they did not yet know what caused the fire.
