The Purification Facility at the Y-12 National Security Complex in Oak Ridge was evacuated Tuesday morning after a chemical spill, officials said. Fewer than 10 people were in the building at the time of the spill, and none were in the immediate area.
There were no injuries, and federal officials and Y-12 staff have accounted for all workers, the National Nuclear Security Administration said.
The spilled material is acetonitrile, a liquid solvent used in chemical processing operations, said Steven Wyatt of the NNSA.
Everyone was evacuated from the building, which is on the east end of the plant, Wyatt said. The spill was reported at 10:24 a.m. Tuesday.
