United Cleanup Oak Ridge LLC (UCOR)

UCOR is an Amentum-led partnership with Honeywell. We are the lead environmental cleanup contractor on the Oak Ridge Reservation (ORR) working under contract with the Department of Energy (DOE) Oak Ridge Office of Environmental Management. In May 2022, UCOR began a 15-year contract to clean up contaminated, unused facilities on the ORR. The current contract follows our successful completion of cleanup of the gaseous diffusion plant at the East Tennessee Technology Park (ETTP) in 2020.
Today, we are cleaning up Manhattan Project-era facilities at the Oak Ridge National Laboratory and the Y-12 National Security Complex. We are also remediating soil and groundwater at ETTP. UCOR also maintains ORR facilities that are waiting for disposition and provides critical, life-extending upgrades to active, aging facilities. All of our cleanup work support efforts to unleash commercial nuclear energy in the Oak Ridge region.

Purpose

We are in the business of safely cleaning up contaminated and often dilapidated facilities for DOE. Because this is high-hazard work, we make safety a prerequisite to everything we do.

As we clean up these old, World War II facilities, we remove both the industrial hazards from decaying structures as well as the potential for remaining contaminants (uranium, mercury, beryllium, asbestos, etc.) to leak into the environment.

Doing this work both safely and expediently is beneficial not only to our workforce and the community, it also is a tremendous savings to taxpayers. Our work goes one step further. Not only do we remove the facilities, we also prepare the land for reuse. At ETTP, our cleanup has enabled DOE to turn over 1,700 acres of land to the community for a variety of uses—economic development, conservation, and historic preservation. In fact, some of the remediated land is planned to be used for a new Oak Ridge airport.

As we remove old facilities at ORNL and Y-12, we are making space for them to modernize in support of their national science and defense missions.

Additional Culture Details

Safety and workforce development are two key pieces of UCOR's culture. We have won numerous national safety awards, including being recognized with the DOE Voluntary Protection Program (VPP) Star of Excellence multiple times and being named to EHS Today's "Safest Companies in America" list.

Our workforce development efforts resulted in UCOR twice winning the Top Workplaces Culture Excellence Award for our Compensation and Benefits program, as well as Culture Excellence Awards for Professional Development and Work-Life Flexibility. We have a number of ongoing workforce development initiatives to ensure that we recruit and retain skilled nuclear cleanup workers. Our new Total Career Management Services program offers our workforce support throughout their time at UCOR. Our certified career counselors deploy resources that support career growth, skill building, and more.

We have a strong summer intern program and anticipate more than 40 interns for our 2025 class. Many of our interns ultimately become full-time employees. UCOR has a University Consortium that includes community colleges and larger universities. As part of our partnership with the University of Tennessee, we developed the nation's first minor in nuclear decommissioning and environmental management.

For our efforts, UCOR received the Tennessee Board of Regents SOAR Partnership Award for our work with Roane State Community College in their chemical operators and environmental health and safety programs.

Values

Make safety a prerequisite to all work
Because we do high hazard work, everyone from the top leadership team to the front line worker is focused on safety and ensuring that our workers are empowered to stop work if there are safety concerns or questions.
