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.

Throwback Thursday | ORNL Low Intensity Test Reactor #UCORTODAY #TEAMUCOR #UCOR #drone
In 2023, UCOR crews safely demolished and removed the three-story tall Low Intensity Test Reactor at Oak Ridge National Laboratory. This 20,000-lb reactor took precision and meticulous training to safely tear down and remove. By April of 2024, the reactor was successfully removed, and the site was cleared for future science missions.
Congrats to Mel McKenzie, a safety specialist with our teaming partner Strata-G, LLC, for receiving the 2026 VPPPA Emerging Safety Leadership Excellence Award! 🏆
Mel was recognized for her worker-centric initiatives that helped UCOR surpass 8 million consecutive work hours without a lost-workday injury.

Our crews are preparing Y-12 National Security Complex’s Beta-4 facility for future deactivation by isolating utilities and removing hazards from the aging-era infrastructure.
We are working alongside Consolidated Nuclear Security to identify and recover more than 550 reusable items that will be repurposed as spare parts and supplies for 76 National Nuclear Security Administration facilities at Y-12. This collaborative effort is reducing environmental risks, protecting ongoing operations, and clearing land to support future national security needs.

EM, NNSA Recover Equipment in Oak Ridge Cleanup for National Security Missions
A partnership between the U.S. Department of Energy’s Oak Ridge Office of Environmental Management (OREM) and the National Nuclear Security Administration (NNSA) is advancing preparations for future demolition of a legacy facility while recovering valuable equipment for national security missions. CNS, Y-12’s management and operating contractor , and UCOR are working together to safely deactivate Beta-4, a 313,000-square-foot former uranium enrichment and weapons production facility at Y-12, for teardown.

Momentum Builds as Crews Take on 2 Demolitions in 1 Year at Y-12 — a First
In a first, the Oak Ridge Office of Environmental Management (OREM) and cleanup contractor United Cleanup Oak Ridge (UCOR) have conducted demolition on two facilities at the Y-12 National Security Complex in a single fiscal year. This project continues to transform and modernize Y-12, highlighting the impact of thoughtful planning and sequencing. UCOR recently began demolishing the 13,000-square-foot Old Steam Plant, also known as Building 9401-1.

Innovative approaches fuel UCOR’s national safety award streak
UCOR has earned its seventh consecutive national innovation award, continuing a multi-year record of improving workplace practices while safely advancing environmental cleanup across the Oak Ridge Reservation (ORR). UCOR President and Program Manager Jim Blankenhorn accepted the Innovation Award at the annual Voluntary Protection Programs Participants’ Association (VPPPA) national conference. VPPPA represents 300,000 workers across the United States and helps worksites improve safety and health practices.

EM Upgrades Ensure ORNL’s Crucial Missions Continue Uninterrupted
The Oak Ridge Office of Environmental Management (OREM) finished a 2.5-year piping replacement project that is crucial to maintain ongoing missions and daily operations at Oak Ridge National Laboratory (ORNL). This life-extension effort involved replacing all above-ground piping for the Liquid and Gaseous Waste Operations (LGWO) system’s Process Waste Facility. The upgrades significantly reduce the risk of outages that would pause operations at the site and the need for frequent maintenance and repairs on the aging infrastructure.
