Wartime Lands Transformed Into 10 Billion Dollar Nuclear Hub at Oak Ridge Tennessee
ENMG Analysis
Decades of environmental cleanup at Oak Ridge, Tennessee, are opening former Manhattan Project and Cold War lands to a new group of nuclear energy companies. The Department of Energy says businesses on land transferred for economic reuse have announced approximately $10 billion in projected capital investment.
The Oak Ridge nuclear hub is part of DOE’s American Energy Hubs initiative, which seeks to put former federal sites to productive use. As of its August 4, 2026, announcement, DOE’s Office of Environmental Management had transferred more than 2,500 acres in Oak Ridge to the community, with additional transfers expected. The acreage represents transfers made over time; the $10 billion represents investment announced by businesses, not completed construction or a single federal financing award. DOE’s Oak Ridge announcement identifies companies working across uranium enrichment, fuel fabrication, advanced reactors, microreactor manufacturing, and fuel recycling.
From Manhattan Project Site to Nuclear Industry Hub
Oak Ridge’s role in nuclear development began during the Manhattan Project. Its federal facilities later supported uranium enrichment, research, and national security work, leaving a substantial cleanup obligation alongside a concentration of technical expertise.
DOE’s Office of Environmental Management and its contractors have spent decades addressing that legacy. According to DOE, redevelopment of the former uranium enrichment complex involved removing more than 500 facilities and excavating more than 50,000 dump truck loads of soil. The work helped make land available for transfer and commercial reuse.
Speaking at the Nuclear Opportunities Workshop in Knoxville, Assistant Secretary of Environmental Management Tim Walsh described the effort as a way to return former federal sites to economic use while supporting new energy development. The Oak Ridge model connects cleanup, land transfer, state and local development efforts, and private investment. It does not eliminate the separate permitting, construction, and regulatory steps each proposed facility must complete.
Companies Span the Nuclear Fuel Cycle
The range of companies involved is a defining feature of the Oak Ridge nuclear hub. DOE identifies Orano USA as planning a uranium enrichment facility, LIS Technologies as developing laser enrichment technology, and BWXT as enriching fuel for national security missions. TRISO-X is constructing a fuel fabrication facility for advanced reactors.
| Company | Sector / Technology Focus | Operational Role at Oak Ridge Hub |
|---|---|---|
| Orano USA | Uranium Enrichment | Developing advanced centrifuge enrichment capabilities to secure domestic fuel supply chains. |
| BWXT | National Security & Commercial Fuels | Manufacturing high-assay low-enriched uranium (HALEU) and specialized nuclear fuels. |
| LIS Technologies | Laser Isotope Separation | Advancing next-generation laser enrichment techniques for high-efficiency fuel production. |
| TRISO-X | Advanced Reactor Fuel | Constructing commercial-scale fabrication facilities for tristructural-isotropic particle fuel. |
| Radiant Nuclear | Microreactor Manufacturing | Producing portable, factory-fabricated microreactors designed for rapid deployment. |
| Oklo Inc. | Nuclear Fuel Recycling | Developing advanced recycling systems to extract energy value from used nuclear materials. |
The area is also attracting reactor and manufacturing projects. Radiant Nuclear has announced a microreactor factory, while Oklo has announced a nuclear fuel recycling facility. These projects are at different stages; an announced investment or planned facility should not be counted as operating nuclear capacity.
The cluster matters because advanced reactors depend on more than reactor construction. Developers also need enrichment, qualified fuel, manufacturing capacity, licensing, and customers. ENMG’s reporting on the Centrus–Radiant HALEU agreement for Kaleidos microreactors examines one fuel-supply relationship relevant to Radiant’s wider deployment plans. That agreement is distinct from Radiant’s proposed Oak Ridge manufacturing facility.
DOE identifies Oak Ridge National Laboratory, the Tennessee Valley Authority, state agencies, local governments, and economic development organizations among the institutions supporting the region’s wider nuclear ecosystem. Their proximity may help companies access expertise and infrastructure, but it does not guarantee that every project will reach commercial operation.
State and Federal Support
Tennessee has committed state resources to expanding its nuclear industry. DOE reports that Governor Bill Lee launched the state’s Nuclear Energy Fund in 2023 and that Tennessee has since allocated $95 million to support nuclear-related businesses, workforce development, and site infrastructure.
Lee and U.S. Representative Chuck Fleischmann have also publicly supported Oak Ridge’s redevelopment. Their involvement reflects the project’s importance to regional jobs, manufacturing, and national energy supply chains. The investment figures remain projections, however, and employment outcomes will depend on individual companies carrying out their announced plans.
Economic and Grid Implications
If the announced facilities are built and operated, Oak Ridge could expand domestic capacity in several parts of the nuclear industry. Enrichment and fuel fabrication are particularly relevant to advanced reactor developers seeking dependable U.S. fuel supplies. Reactor manufacturing and recycling projects would address different parts of the same supply chain.
The electricity implications require a separate distinction. A fuel plant or microreactor factory does not itself add generating capacity to the grid. A reactor project adds electricity only after it completes the required licensing, construction, testing, and connection steps.
Kairos Power’s planned reactor is one Oak Ridge project directly tied to electricity generation for the TVA grid. ENMG has separately covered the NRC review of TVA’s proposed BWRX-300 reactor at Clinch River. Clinch River is a separate project in the Oak Ridge area, not one of the companies or investments being counted here simply because it shares the location. The link connects related regional nuclear development without treating distinct projects as one.
What to Watch Next
The measure of Oak Ridge’s progress will be how many announced projects move through construction and into operation. Readers should watch for company investment decisions, additional land transfers, facility construction, fuel-production milestones, Nuclear Regulatory Commission proceedings where applicable, and any agreements to deliver electricity to the grid.
The approximately $10 billion figure shows the scale of announced private-sector plans attracted to former federal land. It does not establish that the full amount has been spent or that every proposed facility will be completed.
Oak Ridge demonstrates a practical connection between environmental cleanup and industrial development: land once occupied by federal nuclear facilities can be prepared for new uses. Whether the hub delivers lasting manufacturing capacity, jobs, and electricity will be determined project by project.
