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 | ETTP Centrifuge Complex #UCORTODAY #TEAMUCOR #UCOR #satisfying
UCOR crews completed the four‑stage demolition project of the ETTP Centrifuge Reactor, one of the most challenging cleanup projects at the East Tennessee Technology Park. This former enrichment-era facility required extensive planning, specialized equipment, and carefully sequenced teardown activities to safely remove contaminated systems and structural components. The successful completion of all four stages cleared another key legacy structure from ETTP and was a critical step toward clearing 44 acres to be given back to the community for economic development.
Through innovation and efficiency, UCOR saved millions of taxpayer dollars in fiscal year 2026. Our cleanup mission is moving ahead faster and smarter than ever before thanks to cost savings and avoidances. 💸💰
