DOE official outlines Oak Ridge cleanup goals, disposal plans and land transfers

Summary
Eric Oles, manager of the Department of Energy’s Oak Ridge Office of Environmental Management, told the city council the site has met several cleanup milestones and outlined 2026 priorities: demolitions at Y‑12 and ORNL, completing an on‑site disposal design, processing uranium‑233, pursuing land transfers of roughly 4,000 acres, and exploring expanded transuranic processing and AI data‑center opportunities.
Eric Oles, manager of the Department of Energy’s Oak Ridge Office of Environmental Management, told the Oak Ridge City Council at its March 17 work session that the agency has hit several cleanup milestones and outlined a short list of priorities for 2026 and beyond.
Oles said DOE completed demolition of Alpha‑2 at the Y‑12 National Security Complex and is preparing Beta‑1 and other facilities for demolition. “Disposal is really the engine that drives clean up,” he said, urging timely construction of a next Environmental Management Disposal Facility so the site does not run out of on‑site disposal capacity.
Among the site’s near‑term goals, Oles listed finishing demolition work at both Y‑12 and Oak Ridge National Laboratory (including Isotope Row), reaching the halfway mark on processing and disposing of the site’s uranium‑233 inventory, and beginning support‑facility construction for a new on‑site disposal facility. He also said DOE is pursuing transfers of roughly 4,000 acres to the community, including portions of the Heritage Center/ETTP footprint.
On transuranic (TRU) waste, Oles described Oak Ridge’s Transuranic Waste Processing Center (TWPC) as a rare, mission‑critical facility and said Oak Ridge is discussing agreements to process TRU containers for other sites so the waste can be shipped to the Waste Isolation Pilot Plant (WIPP) in Carlsbad, N.M. He stressed that any processing would be followed by shipment to WIPP, not indefinite storage at Oak Ridge.
Council members pressed Oles about whether state politics in New Mexico — where WIPP is located — could slow shipments. Oles replied that Los Alamos has a standing “ready to ship” agreement with WIPP and that the materials he discussed are already forecasted in WIPP planning, so he did not expect program‑level bottlenecks, though headquarters is actively discussing state concerns.
Oles also confirmed DOE has paused construction of a mercury treatment facility at Y‑12 while a team including ORNL and regulators reviews technologies and remediation approaches. “I have paused construction on the facility,” he said, adding that the work already done will be placed into surveillance and maintenance so it can be resumed if the team recommends moving forward.
On beneficial reuse, Oles highlighted uranium‑233 down‑blending at ORNL that yields thorium and other isotopes; he said a private partner extracts actinium that is moving through clinical trials for cancer treatment. He called the reuse a positive example of extracting value from legacy materials.
Oles said DOE is also revisiting land‑lease opportunities for large AI data centers and coordinating with TVA on power and transmission needs. He encouraged early city involvement in master‑planning for transferred lands so private development and recreational uses can be integrated.
Oles closed by saying his office will return with more detailed options later this year and asked to continue the partnership with the city.
Next steps: DOE will complete groundwater monitoring for the disposal design, the internal team will recommend a path forward for the mercury remedy later this spring, and Oles said he expects to return to council with additional details when more agreements or proposals are finalized.
