From Remediation to Renaissance: EM Builds Foundation for New Nuclear Era

The U.S. Department of Energy’s Idaho Cleanup Project hosted an industry day for companies responding to a request for applications to build a commercial-scale recycling plant at an Office of Environmental Management facility at the Idaho National Laboratory Site.

The U.S. Department of Energy's (DOE) Office of Environmental Management (EM) mission is expanding from legacy cleanup to laying the foundation for America’s new nuclear energy era.

This enhanced mission reflects Energy Secretary Chris Wright's agenda: ensure nuclear deterrence, position the United States as the global leader in science and innovation, and drive American energy dominance to keep consumer prices low and competitive with industry.

"We aren't just managing the past; we are powering the future," Assistant Secretary of Environmental Management Tim Walsh told attendees of the Waste Management Symposia in March.

He outlined the transformation potential of each EM cleanup site by 2040, accelerating remediation while converting former weapons production facilities into hubs for nuclear energy, advanced manufacturing and artificial intelligence (AI) infrastructure.

Across the EM complex, the transition from environmental remediation to a nuclear renaissance is already taking shape, marked by major operational milestones transforming former weapons facilities into vital energy assets.

A Year of Milestones

At the Idaho Cleanup Project, the team made 40 transfers of used nuclear fuel bundles from aging first-generation storage vaults to new, second-generation vaults — finishing months ahead of schedule. This effort ensures the used fuel is in protective storage and stable condition awaiting opportunities for recycling.

In addition, the Integrated Waste Treatment Unit (IWTU) has converted over 375,000 gallons of liquid sodium-bearing waste into a safer, solid form, reducing risk to the underlying Snake River Plain Aquifer from a liquid by-product. As IWTU crews continue waste treatment, the Idaho National Laboratory (INL) is enabled to receive additional research quantities of commercial used nuclear fuel for advanced energy research under the 1995 Idaho Settlement Agreement.

Last year, the state of Idaho signed a waiver to that agreement, clearing the way for INL to receive a research cask containing used nuclear fuel from the North Anna Generating Station in Virginia. EM crews at the site are also preparing for a used nuclear fuel shipment from a research reactor at Penn State University this year for the first time in decades.

At the Savannah River Site (SRS) in South Carolina, a historic pivot is underway to fuel America’s nuclear future. EM announced the decisions to restart uranium recovery operations at H Canyon, the only chemical separations facility of its kind in the U.S., and bring the adjacent HB-Line facility back online. Rather than preparing legacy used nuclear fuel and surplus plutonium for permanent disposal, SRS is restoring its one-of-a-kind capabilities to recycle these materials. EM will transform legacy nuclear materials into valuable assets to fuel next-generation advanced nuclear reactors.

At Oak Ridge, where EM has transferred more than 2,500 acres of federal land for community reuse, the company Kairos Power is constructing a $100 million demonstration reactor. Orano USA has selected the site for a new multibillion-dollar uranium enrichment facility, and Triso-X broke ground on a fuel fabrication plant that will be the first of its kind in the U.S. Together, more than two dozen businesses have announced $10 billion in capital investments at Oak Ridge.

Opening the Door to Private-Sector Used Fuel Recycling

EM and DOE's Offices of Nuclear Energy concurrently issued two requests for applications (RFA) seeking private-sector partners to design, build and operate used nuclear fuel recycling and conditioning facilities in the U.S.

EM's RFA offers a selected private partner a long-term lease of prime federal land at the Idaho Nuclear Technology and Engineering Center (INTEC) at the INL Site. The RFA also offers access to Advanced Test Reactor used nuclear fuel currently stored at the INL Site. This provides a direct, highly valuable feedstock for recycling, allowing private industry to transform this used nuclear fuel to power the next-generation advanced reactors.

"This initiative is a testament to President Trump's bold vision for American energy independence and our commitment to an unmatched national security posture," Walsh said.

EM’s recent, highly successful Industry Day event drew strong commercial interest and fostered collaborative discussions, setting the stage for private sector ingenuity to officially power America's nuclear renaissance. Final applications are due June 19. Contact Aaron S. Nebeker at nebekeas@id.doe.gov for more information on EM’s RFA.

Building for What Comes Next

EM is investing in infrastructure for the future. In May, DOE approved the conceptual design for a new 15,000-square-foot used nuclear fuel staging facility at INTEC. And across the DOE complex, new reactors, enrichment facilities, recycling capabilities and AI infrastructure are being built on land and using materials that EM has spent 35 years making safe.
