As the US scrambles to replace Russian nuclear fuel and feed an energy-hungry digital economy, France’s Orano has just been handed a pivotal role: building a brand-new uranium enrichment plant on American soil, backed by hundreds of millions of US federal dollars.
France’s Orano lands a $900 million bet from Washington
The US Department of Energy (DOE) has approved up to $900 million in funding for Orano to launch a new uranium enrichment capacity in the United States.
This public support forms part of a far larger industrial package worth close to $5 billion, centred on a planned plant in Oak Ridge, Tennessee.
The project represents a concrete step in Washington’s effort to rebuild a full domestic nuclear fuel cycle after decades of outsourcing key stages, including to Russia.
The US is paying France’s Orano to help restore a fuel-making capability that underpins both its energy security and its geopolitical leverage.
The timing is not accidental. From 2028, US law will ban imports of Russian enriched uranium, currently a major source for American reactors. That looming cut-off date acts as a ticking clock for utilities and policymakers alike.
Why uranium enrichment suddenly matters again
Nuclear reactors do not run on raw uranium dug straight from the ground.
They need fuel in which the proportion of uranium-235 — the fissile isotope — has been increased through a tightly controlled process called enrichment.
That enrichment step sits between uranium mining and fuel fabrication. It is highly technical, heavily regulated and strategically sensitive, because the same technologies can, in principle, be used to produce weapons-grade material.

France, through Orano, has spent decades refining centrifuge technologies and operating large-scale enrichment plants. That expertise is now being tapped by Washington at a moment when the US finds itself short on domestic capacity.
For years, American utilities relied on a mix of domestic facilities, European suppliers and Russian state company Rosatom. The war in Ukraine, sanctions policy and growing bipartisan concern about dependence on Moscow have turned that model into a liability.
By 2028, US utilities will have to run nuclear fleets without Russian enriched uranium, forcing a rapid reshaping of global fuel supply chains.
The IKE project: symbolism meets hard industry
A name with a Cold War echo
The DOE-backed scheme carries a deliberate name: IKE, a nod to former US president Dwight D. Eisenhower and his 1953 “Atoms for Peace” speech.
The message is straightforward. The US wants to re-anchor a complete civilian nuclear capability on its own territory, from enriched fuel to kilowatt-hours on the grid, in partnership with allies.
The choice of Oak Ridge also sends a signal. The Tennessee site is one of the cradles of the US nuclear programme, dating back to the Manhattan Project. Today, it hosts labs, regulators and industrial players, creating an environment where a complex facility like an enrichment plant can plug into existing expertise and oversight.
How Orano’s technology fits in
Orano plans to deploy its ultracentrifuge technology, proven for more than forty years in France.
- It uses fast-spinning centrifuges to separate uranium isotopes.
- It consumes far less electricity than the old gaseous diffusion process.
- It allows fine control over enrichment levels, crucial for modern reactor designs.
While the details of the IKE plant’s capacity remain under wraps, the goal is clear: create a large, flexible source of low-enriched uranium (LEU) and advanced fuels that US reactors — existing and future — can rely on without political drama.
Licences, timelines and regulatory shortcuts
The DOE money does not mean shovels hit the ground tomorrow. Orano first needs to finalise its contractual arrangements and secure authorisation from the US Nuclear Regulatory Commission (NRC).
The company aims to wrap up the federal contract and file its licence application in the first half of 2026.
Nuclear licensing in the US remains demanding, with extensive safety, environmental and non-proliferation reviews. Even with political support, every stage requires detailed technical justification and public scrutiny.
The targeted start of production sits around the early 2030s, with a gradual ramp-up to serve both today’s large reactors and emerging designs like small modular reactors (SMRs).
| Key step | Target period |
| Federal contract finalised | 1st half of 2026 |
| Licence application filed with NRC | 2026 |
| Construction and commissioning | Late 2020s |
| Start of production | Early 2030s |
Why AI and data centres are pushing nuclear back into the limelight
The IKE project is not only about disentangling supply chains from Russia.
It also rides a deeper structural shift in US power demand.
Data centres and artificial intelligence workloads are driving steady, round-the-clock electricity consumption across the country. These facilities cannot easily adapt to swings in output from solar or wind farms. They need stable, dispatchable power.
Nuclear fits that bill. Reactors run 24/7, produce very low carbon emissions and occupy relatively small land areas compared with large renewable installations.
In a grid reshaped by AI and cloud computing, reliable baseload power becomes a strategic asset, not just an engineering detail.
Recent US administrations, particularly since Donald Trump’s second term and subsequent policy shifts, have leaned into that logic. A presidential order in May 2025 simplified certain licensing procedures for nuclear projects, gave the federal government tighter steering over the NRC and eased some radiological norms for reactors sponsored by the Department of Energy or the Pentagon.
The goal: accelerate advanced reactors and micro-reactors that could power isolated military bases, critical industrial sites or energy-hungry digital hubs.
Other policy texts set a more distant but striking objective — roughly quadrupling installed nuclear capacity over the long term, using SMRs and advanced designs to compete head-on with China and Russia in both technology and exports.
Orano’s journey from quiet supplier to strategic linchpin
For Orano, the US funding crowns almost fifty years of steady, sometimes low-profile work on the nuclear fuel cycle.
The company traces its roots back to Cogema, founded in 1976 to give France control over every stage of nuclear fuel, from uranium mining to reprocessing.
Rebranded as Orano in 2018, the group rode out political swings, public debates over nuclear safety and market downturns. Throughout, it stuck to its core skills: conversion, enrichment, fuel logistics and waste management.
Today, about 16,500 employees generate around €5 billion in annual revenue, supported by flagship facilities such as Georges Besse II at Tricastin. That plant is one of the largest enrichment sites on the planet, serving reactors in over 30 countries.
The Oak Ridge project shifts Orano into a new league. It is no longer simply an export supplier shipping cylinders of enriched uranium from France. It becomes embedded in US infrastructure, under American regulatory scrutiny, supplying a fleet that Washington views as critical for national security and climate goals.
By hosting Orano’s centrifuges, the US effectively shares part of France’s nuclear know-how while anchoring it inside its own borders.
The current US enrichment map — and the gap IKE aims to fill
For a country with the world’s largest commercial nuclear fleet, the United States now has surprisingly few active enrichment facilities.
| Site / plant | State | Main status | Primary technology |
| Urenco USA (Eunice) | New Mexico | In operation (only large-scale active plant) | Gas centrifuges |
| Portsmouth Gaseous Diffusion Plant | Ohio | Shut down, in decommissioning | Historic gaseous diffusion |
| Paducah Gaseous Diffusion Plant | Kentucky | Shut down (2013), storage and cleanup | Historic gaseous diffusion |
| Oak Ridge Y-12 (Centrus Energy) | Tennessee | HALEU demonstrator in operation | Advanced centrifuge demonstration |
| American Centrifuge Plant (Piketon) | Ohio | Project in development | Gas centrifuges |
At scale, Urenco’s plant in New Mexico currently shoulders most of the commercial enrichment burden in the US, and it is owned by European governments and utilities.
Oak Ridge, by contrast, is set to host a large facility controlled by an allied, but non-US, industrial player operating under a US-regulated framework. That diversity reduces supply risk, but also raises questions about long-term contracts, pricing power and how much the US wants to rely on foreign corporations, even friendly ones, for critical fuel-cycle steps.
Risks, benefits and the geopolitics of fuel
Uranium enrichment always carries two parallel narratives: one about electrons on the grid, the other about strategic leverage.
On the positive side, IKE promises skilled jobs in Tennessee, new tax revenue and a boost for local research institutions. It also tightens links between US and French industries at a time when both face competition from Russia’s Rosatom and China’s sprawling state-backed nuclear sector.
On the risk side, large enrichment plants must manage sensitive materials, complex safety systems and strict non-proliferation rules. Any incident, even minor, would quickly turn into a political flashpoint. There is also the financial risk of overbuilding capacity if SMRs or advanced reactors grow more slowly than expected.
For investors and policymakers, one key variable will be fuel diversification. Utilities are likely to juggle contracts with Orano, Urenco and emerging US players to avoid concentration on a single supplier or technology.
Key terms and what they mean in practice
For non-specialists, a few concepts help make sense of the stakes around Oak Ridge.
- LEU (Low-Enriched Uranium): Fuel containing typically 3–5% uranium-235, used in standard commercial reactors.
- HALEU (High-Assay Low-Enriched Uranium): Between 5% and 20% uranium-235, needed for many advanced and micro-reactor designs.
- Gas centrifuge: A tall, spinning cylinder that separates isotopes by mass; thousands are combined in “cascades” to reach the desired enrichment.
- Fuel cycle: The full chain from mining to disposal, including conversion, enrichment, fabrication and sometimes reprocessing.
In practice, if IKE can produce both LEU and, eventually, HALEU, it will give the US and its allies a stronger hand in rolling out new reactor designs at home and abroad. Without reliable suppliers of these fuels, many promising nuclear technologies stay stuck on paper.
The Oak Ridge project, then, sits at an intersection where industrial engineering meets high politics. France brings a mature, tested enrichment toolkit. The US brings market size, regulatory power and geopolitical reach. Together, they are trying to rebuild a part of the nuclear ecosystem that many governments assumed would just keep running quietly in the background — until the geopolitics of uranium snapped into focus again.
