Safely Reducing Environmental Risks. 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.

Cleanup crews in the Oak Ridge National Laboratory (ORNL) central campus have filled 120 feet of underground ductwork connecting multiple facilities with a cement mixture to isolate them for safe demolition and avoid potential impacts to neighboring buildings. The Oak Ridge Office of Environmental Management and cleanup contractor United Cleanup Oak Ridge (UCOR) completed the project to prepare for demolition of Building 3002, a former filter house used to clean exhaust from the nearby historic Graphite Reactor.

What's New
Oak Ridge crews are deactivating Beta-4, which spans the equivalent of nearly seven football fields, as similar preparations for demolition draw to a close at another former Manhattan Project-era uranium enrichment facility, Beta-1, at the Y-12 National Security Complex. This marks a significant step forward in the Oak Ridge Office of Environmental Management’s (OREM) effort to remove legacy hazards, enable modernization and open space for important national security missions at Y-12.

What's New
A detailed data-gathering process known as characterization is helping the Oak Ridge Office of Environmental Management (OREM) advance cleanup at one of the nation’s most important national security sites. Teams are characterizing land, buildings and slabs to identify contamination at the Y-12 National Security Complex. Field work underway by contractor United Cleanup Oak Ridge (UCOR) and subcontractor RSI EnTech is paving the way for upcoming demolition and land reuse at Y-12.

What's New
A demonstration of an innovative technology has proved successful in safely treating and permanently disposing of a complex legacy waste stored at Oak Ridge National Laboratory (ORNL) for the past 50 years, reducing significant risk. “This effort demonstrates how innovation and strong partnerships can solve some of the most complex cleanup challenges,” said Steve Clemons, ORNL portfolio federal project director for the Oak Ridge Office of Environmental Management (OREM).
