What We Do

UCOR’s workforce is conducting major cleanup activities at the Oak Ridge National Laboratory and the Y-12 National Security Complex as well as remedial activities at the East Tennessee Technology Park (ETTP). We also operate the Transuranic Waste Processing Center and are constructing the Outfall 200 Mercury Treatment Facility. Under the previous contract, UCOR was DOE’s prime contractor for environmental cleanup at ETTP, where we completed a first-in-the-world cleanup of a gaseous diffusion plant. As a DOE Voluntary Protection Star site—the highest safety designation for a DOE site—we make safety a prerequisite to all that we do.

Cleaning up the Oak Ridge Reservation

Cleanup missions on the Oak Ridge Reservation (ORR) focus on protecting people and the environment from industrial and chemical hazards while enabling current and future science and national security programs. We achieve these goals by working safely, maintaining strong partnerships, and always finishing what we start.

Specific Tasks

Our work scope on the ORR includes demolition, remediation, and operational support.

Demolition

Utility Isolations (also known as Cold and Dark)

Disconnecting the building or structure from all utility sources
(e.g., electricity, water, gas, alarms)

Deactivation

Identifying hazards (e.g., structural deterioration, contamination) and removing hazardous and radioactive materials, equipment, piping, universal waste (e.g., light bulbs, batteries, circuit boards), asbestos, and other items prior to demolition.

Demolition

Destruction and removal of physical facilities and structures, usually accomplished with heavy and/or high-reach equipment

Waste Management & Disposal

Packaging, loading, shipping, and disposing of all waste (e.g., equipment, construction debris, soil) from deactivation, demolition, and remediation activities

Remediation

Identifying the extent of contamination of soil, groundwater, sediment, or surface water around the demolition area through sampling (characterization) and removing those contaminants through excavation or treatment (remedial actions)

Operational Support Tasks

Nuclear Operations

Ensuring 24/7 operations of the Liquid & Gaseous Waste Operations (LGWO) facility, which treats contaminated waste from cleanup activities and mission-critical science programs

Surveillance and Maintenance

Providing surveillance and maintenance services for nuclear facilities awaiting demolition, including periodic inspections and maintenance of structures, systems, and equipment to ensure hazards are contained.
