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.

Before the sparks fly this holiday, let’s make sure we’re keeping our loved ones and neighbors safe. 🇺🇸✨
Keep these essential safety habits in mind:
• Never re-light duds: Soak failed fireworks in water—never try to relight them.
• Stay sober: Keep the designated firework shooter completely sober.
• Keep a safe distance: Spectators should stand far back, and shooters should wear eye protection.
• Know your laws: Only use legal consumer fireworks.
Our safety commitment doesn't end when the workday does. UCOR reminds you to take safety home with you. Have a fun, safe holiday!

Big progress at Oak Ridge National Laboratory! UCOR crews have finished deactivating the 10 facilities known as "Isotope Row." These buildings supported medical and scientific research for decades but required a major, complex cleanup. Thanks to our workers' expertise, we have removed hazards and safely prepped the site for demolition, which will begin this July. We are proud to help modernize the campus for the next generation of scientific discovery!

The Waste Management team at the Oak Ridge Reservation Landfill recently finished a major maintenance project at Pond 2.
The crew cleans the pond every few years to keep it working properly. This time, workers removed 85 truckloads of soil. Instead of throwing it away, the team is drying the soil to reuse as landfill cover. This step saves clean soil and reduces waste.
After the cleanout, the crew used 73 truckloads of clean soil to rebuild the floor. They also placed about 200 tons of stones to rebuild the wall and stop erosion.
Pond 2 is now filtering water exactly as planned! Great job to everyone who helped keep our facility running smoothly and sustainably.

ORNL’s Isotope Row is Ready for Demolition Following Deactivation Work
Oak Ridge Office of Environmental Management (OREM) crews have prepared a cluster of highly contaminated buildings for teardown on one of the most challenging footprints at Oak Ridge National Laboratory (ORNL) after finishing deactivation work there. Located in the ORNL’s central campus, Isotope Row consists of 10 facilities constructed between the late 1940s and early 1960s that previously supported the laboratory’s isotopes program.

Cleanup Efforts Expand Across Oak Ridge National Laboratory’s Central Campus
Cleanup progress continues across Oak Ridge National Laboratory (ORNL), where workers recently began preparing another facility for demolition as they remove hazards and pave the way for the next chapter of scientific discovery and innovation at the site. The Oak Ridge Office of Environmental Management (OREM) and contractor United Cleanup Oak Ridge (UCOR) are characterizing and deactivating Building 3544, a former waste treatment plant, along with other infrastructure on the building’s footprint, including a wastewater plant.

Oak Ridge Exceeds First-Year Goal for Legacy Oxide Waste Processing
The Oak Ridge Office of Environmental Management (OREM) and contractor United Cleanup Oak Ridge (UCOR) have achieved the first-year goal for processing oxide waste at the Transuranic Waste Processing Center (TWPC) months ahead of schedule, progressing toward the removal of this legacy material from the Oak Ridge Reservation. Typical transuranic waste, such as equipment, tools or protective materials, contains low levels of radioactive contamination.

UCOR Wins National Awards for Demolition Project, Safety Performance
United Cleanup Oak Ridge LLC’s (UCOR) successful teardown of a massive, Manhattan Project-era facility has earned national recognition for project execution and safety excellence. UCOR recently won the “2026 Union Project of the Year Award” from The Association of Union Constructors (TAUC), which represents over 1,800 companies that use union labor. Presented at TAUC’s Annual Meeting, the award recognizes the skilled UCOR workforce for demolishing the Alpha-2 Complex, a 2.5-acre former uranium enrichment facility at the Y-12 National Security Complex.
