Centrus's Piketon enrichment plant, Oklo's planned Aurora reactors, construction firm Kiewit, and Meta's power demand all point to Pike County, but the fuel letter is nonbinding and 2029 delivery is contingent on a production ramp.
In a single southern Ohio county, the pieces of America's advanced nuclear comeback are starting to click together. The latest thread is a nonbinding letter of intent under which Centrus Energy would supply enough high-assay low-enriched uranium (HALEU), a higher-enrichment form of reactor fuel the U.S. has historically struggled to produce at commercial scale, for up to five of Oklo's planned Aurora reactors, with deliveries scheduled to begin in 2029 (Centrus and Oklo press release, June 18, 2026).
The fuel would come from Centrus's American Centrifuge Plant in Piketon, Ohio, the same Pike County facility where the company is already scaling HALEU production under a previously announced U.S. Department of Energy task order (PR Newswire, June 18, 2026). Oklo, a publicly traded advanced reactor developer, says the fuel is intended for its planned 1.2 gigawatt "Clean Energy Campus" of small Aurora powerhouses in southern Ohio, a separate project from the Aurora-INL combined license application Oklo has pending with the U.S. Nuclear Regulatory Commission.
What makes the announcement more than a single fuel deal is what is converging around it. On June 18, 2026, Oklo and Centrus signed the fuel letter of intent. The same day, Oklo and Kiewit Nuclear Solutions, a unit of construction firm Kiewit, signed a separate memorandum of understanding covering engineering, procurement, and construction planning for initial Aurora deployments. And in January 2026, Oklo announced a power purchase agreement with Meta under which Meta would prepay for electricity from Aurora plants, the kind of customer-side financing structure the press release says the Centrus letter "could include" as well (PR Newswire, June 18, 2026).
For years the dominant constraint on U.S. advanced nuclear has been supply: whether the country could produce HALEU at all, in the right quantities, on the right timeline. The Centrus letter does not resolve that question, but it does signal that the constraint is shifting from "is there domestic fuel?" toward "can the supply chain be financed, sequenced, and built on schedule?" A 2029 first-delivery date assumes the Piketon centrifuge cascade continues to ramp. Centrus's own public statements about the plant's production trajectory, and any independent read of whether that ramp supports the volumes the Oklo letter anticipates, are the open question the press release does not answer.
Two caveats belong in the reader's hands. The Centrus letter is a letter of intent, not a definitive contract, and the press release says the companies "anticipate" a future definitive agreement, so the deal could still shift in price, volume, or timing. The release also frames the broader project as a "multi-billion-dollar private clean energy investment" creating "hundreds of jobs" in southern Ohio, but those numbers are company-stated projections, not independently validated outcomes.
What to watch next: whether Centrus and Oklo convert the letter into a signed, priced contract; whether the Piketon cascade hits the production volumes needed for a 2029 first delivery; whether Oklo's Kiewit MOU produces a fixed-price engineering, procurement, and construction agreement; and whether the Aurora-INL license application, the regulatory permission that is the closest thing to a hard gate on the whole pipeline, advances on a schedule that lines up with the fuel deliveries.
