We are cleaning up contaminated, unused facilities on the Oak Ridge Reservation (ORR). In addition to removing excess facilities, we maintain facilities across ORR that are waiting for disposition. We also provide critical upgrades to extend the life of active, but aging, facilities. This continues the same work done by the former UCOR from 2011 to 2022.
