East Tennessee Technology Park

Since 2011, UCOR has worked to clean up the East Tennessee Technology Park, formerly the Oak Ridge Gaseous Diffusion Plant (K-25), which produced enriched uranium for defense and commercial purposes until being shut down in 1987. The goal for this cleanup has been to create three specific end states for reuse of the land: a multi-use industrial park, national park, and conservation area.

In 2016, UCOR completed DOE's milestone to remove the five gaseous diffusion buildings. In 2020, crews will achieve the next milestone to demolish all remaining unneeded structures and complete critical remedial actions.

Oak Ridge National Laboratory

UCOR is working on the Oak Ridge National Laboratory (ORNL) campus to maintain existing facilities and clear the way for future modernization. Our crews are assisting with surveillance and maintenance operations on the ORNL campus. UCOR is also working to deactivate a number of the site’s excess contaminated facilities to prepare them for eventual demolition.

ORNL operates the largest open science laboratory in the DOE complex. Its mission is to deliver scientific discoveries and technical breakthroughs. UCOR's work will help DOE to continue and expand ORNL's vital mission.

Y-12 National Security Complex

At the Y-12 National Security Complex (Y-12), UCOR is actively working to deactivate and demolish five high-risk excess contaminated facilities, known as the Biology Complex, as well as other excess contaminated facilities. Crews are also supporting the remediation and treatment of mercury that leached into the environment during Y-12 Complex operations during the 1950s and early 1960s.

Y-12 is an active federal facility that maintains the nation’s nuclear stockpile, protects against global security threats, and fuels the U.S. Nuclear Navy. By working with DOE to address these issues, UCOR is helping enable future missions at the site.
