What We Do

Safely Reducing Environmental Risks

Since 2011, we have been cleaning up contaminated, unused facilities on the Oak Ridge Reservation (ORR). In 2020, we became the first in the world to safely remove a gaseous diffusion plant. In addition to removing excess facilities, we maintain facilities across ORR that are waiting for disposition, and provide critical upgrades to extend the life of active, but aging, facilities.
