A large award for a project with a long past
In January 2026, the Department of Energy selected American Centrifuge Operating for a $900 million award to develop domestic production capacity for high-assay low-enriched uranium, known as HALEU. The recipient is a Centrus Energy subsidiary working at Piketon, Ohio. DOE placed the award inside a broader $2.7 billion enrichment program and said payments would follow milestones. The announcement financed work toward new capacity; it did not mean a large new plant was already producing fuel. [1]
Piketon’s importance preceded the latest nuclear revival. The federal government built enrichment infrastructure there decades earlier, and the American Centrifuge project tried to turn that inheritance into a commercially viable successor. Its history includes a licensed plant, an uncompleted financing plan, corporate bankruptcy, a smaller demonstration and a renewed expansion. The same location and related technology appear across those stages, but their financial arrangements and intended outputs changed. [2] [3]
What enrichment adds to uranium
Nuclear fuel depends on more than mining uranium. Enrichment increases the proportion of uranium-235, the isotope useful for sustaining the reactor’s chain reaction. Existing power reactors typically use fuel enriched to roughly 3%–5%; HALEU is above 5% and below 20%. Many advanced designs seek that higher concentration to support smaller cores or longer operating cycles. The extra enrichment must occur before the material can be made into finished reactor fuel. [4]
At Piketon, centrifuges handle uranium hexafluoride, or UF6. The machines are connected in a cascade that progressively changes the isotopic composition. This creates two distinct measures: the enrichment percentage and the amount of material produced. There is also a mass distinction. GAO explains that 900 kilograms of HALEU UF6 includes fluorine and corresponds to about 600 kilograms of uranium after that fluorine is removed. A shipment of UF6 is not the same weight of fabricated nuclear fuel. [2]
The original commercial plan depended on financing
The Nuclear Regulatory Commission received the American Centrifuge Plant application in 2004 and issued its license in 2007. The proposal used existing federal buildings at Piketon. A license authorized a facility within regulatory conditions; it did not supply construction money or ensure favorable market prices. The NRC’s project history distinguishes the proposed commercial plant from the smaller lead cascade used to test the technology. [5]
USEC, the company later renamed Centrus, sought a $2 billion federal loan guarantee to support commercialization. Its 2013 annual report says prevailing market conditions meant that even the requested guarantee would not, by itself, make the project economically viable without further government support. USEC filed for Chapter 11 on March 5, 2014. That corporate restructuring was part of a wider business transition, including the end of enrichment at its older gaseous-diffusion operation; it was not proof that every centrifuge at Piketon had technically failed. [3]
Government support bought development time
The public role was already substantial. In March 2010, DOE announced a $90 million cost-shared demonstration agreement. Its $45 million contribution used an unusual mechanism: the department would take title to depleted uranium material, permitting USEC to release funds previously tied up for that material’s eventual disposal. The support therefore was not simply an ordinary cash grant for a completed commercial factory. [6]
DOE’s inspector general later reported approximately $397 million of federal support for centrifuge research, development and demonstration from June 2012 through September 2015. When that support ended, Centrus could not continue operating the demonstration plant without further assistance and announced demobilization plans in 2016. The earlier project left technology and experience, but not the self-funding commercial facility originally envisioned. [7]
HALEU gave the project a different job
In 2019, DOE contracted with American Centrifuge Operating to assemble a 16-machine cascade demonstrating HALEU production. Rather than immediately building the original large plant for ordinary reactor fuel, the new effort targeted a smaller quantity of a more highly enriched product needed by emerging reactor designs. A later contract shifted the work from assembly toward startup and continued operation. [8]
DOE’s February 2023 explanation set out the intended sequence: initial production of 20 kilograms, followed by an annual production rate described as 900 kilograms. The federal purpose included fuel qualification, testing and early advanced-reactor needs. Those targets were the bridge between a working enrichment process and a future supply chain, not a declaration that all proposed reactors already had commercial fuel available. [8]
Real production, with a precise unit
DOE reported in June 2025 that the first 900-kilogram milestone had been achieved and that another year of production had been commissioned. It said the material would support its allocation process for advanced-reactor fuel qualification and testing. GAO’s later account clarifies that this milestone was 900 kilograms of HALEU in UF6 compound form, approximately 600 kilograms of contained uranium. The distinction matters when comparing the demonstration with reactor demand stated in tonnes of uranium. [9] [2]
Centrus then reported on July 1, 2026 that it had completed the final additional 900 kilograms of HALEU UF6 in mid-June, two weeks ahead of schedule. It put cumulative production over the contract’s life above 1,900 kilograms of the compound. The July announcement was the reporting date; mid-June was the stated completion period. This was measured demonstration production, distinct from the substantially larger capacity the company was preparing to build. [10]
Procurement success and procurement scrutiny coexist
The demonstration’s output did not erase questions about how its original contract had been awarded. In a July 2, 2025 audit, DOE’s inspector general found that restrictive requirements had limited competition for the 2019 sole-source award and identified financial risks at the selected contractor. The report questioned whether the government had obtained best value. These were procurement findings concerning the award process, not a finding that the later reported fuel output was fictitious. [7]
The audit made no recommendations because more than six years had passed since the procurement decision. Departmental management chose not to provide official comments, the report says. The distinction is important in a long-running industrial program: producing the intended material and demonstrating that an award was competitively and financially well structured are separate questions. [7]
The next stage combines public money and commercial commitments
On July 1, 2026, Centrus said it had signed the contract finalizing its $900 million award. The new fixed-price arrangement supported commercial-scale capacity and included discretionary DOE purchase options worth up to another $170 million. Centrus expected first new capacity in 2029 and intended to operate the existing demonstration cascade commercially in the meantime, subject to enabling agreements, including a longer-term site lease. These remained company plans, not completed operating milestones. [10]
Its August results showed how customer promises fit the financing. Centrus reported $3 billion of contingent LEU and HALEU sales commitments, including $2.4 billion under definitive agreements, supporting potential Piketon construction. The commitments remained linked to operating milestones. The same report said the older demonstration-contract backlog included unexercised options that DOE did not then intend to exercise. A large backlog could therefore combine very different kinds of future revenue. [11]
Capital raised today, capacity expected later
Private financing also expanded. A September 9, 2026 securities-offering announcement priced shares and warrants with approximately $500 million in expected gross proceeds, before expenses. The release separately identified possible future proceeds from common-warrant exercises and did not include them in that $500 million. It described broad corporate uses, including technology deployment and capital spending; the announcement was not a claim that the entire amount had already been spent in Ohio. [12]
Piketon had consequently reached a different position from the stalled project of the previous decade: it had demonstrated HALEU output, a new federal capacity contract and prospective commercial customers. Yet industrial-scale supply still required new equipment, construction, operating approvals and performance under contracts. The story’s financial turning point is the attempt to connect those stages with milestone payments and private capital, while the larger production outcome remains ahead. [1] [10] [11]
