Local media reported that the production affected was "Building 9212, a uranium procession facility." That is, the kind of place a fire is not ideal.
Personnel have determined the event is contained to the production building. Evacuations have been conducted in the area. There are no reports of injury or contamination as a result of the event.

So, the good news is no one was injured and no radiation leaks were detected. Still, the cause of the fire remains unknown and Y-12 has undertaken an investigation.
The complex is "a premier manufacturing facility dedicated to making our nation and the world a safer place and plays a vital role in the Department of Energy’s Nuclear Security Enterprise" while helping "ensure a safe and effective U.S. nuclear weapons deterrent."
To conduct this work, the Y-12 National Security Complex says it also retrieves and stores nuclear materials, fuels the nation’s naval reactors, and performs complementary work for other government and private-sector entities.
After responding, Y-12 officials reported that the fire remained contained and evacuations were ordered. No injuries or contamination was reported during the response.
