Oklo Ohio Campus

Executive Overview

The Oklo Ohio Campus is a planned 1.2 GW advanced nuclear power campus under development on 206 acres in Pike County, Ohio, by Oklo Inc., with Meta as the anchor customer and funding partner. The agreement — announced in January 2026 — provides for Meta to prepay for power and fund early procurement and development activities, with pre-construction and site characterisation scheduled to begin in 2026. The first phase is targeted to come online as early as 2030, with the full 1.2 GW capacity expected by 2034. The site is located within the PJM interconnection, one of the largest grid systems in the United States, and forms part of the broader redevelopment of the former Portsmouth Gaseous Diffusion Plant site in southern Ohio. Third Way has described Meta's broader nuclear investment — of which Oklo Ohio is the centrepiece — as the largest corporate investment in nuclear energy in U.S. history.

How It Works & Differentiation

The campus will be built from multiple Oklo Aurora powerhouses, each a compact fast fission reactor fuelled by HALEU recovered from used nuclear fuel, including material from the EBR-II. The Aurora design uses advanced fuel recycling technology, reducing long-lived waste relative to conventional light-water reactors, and is engineered for passive safety without requiring active cooling systems. Oklo was the first company to receive a DOE site-use permit at Idaho National Laboratory for a commercial advanced fission plant, and the first to submit a custom combined license application to the NRC. The campus's modular structure — scaling incrementally from first phase to 1.2 GW — allows for phased capital deployment and risk management in a way that single-unit large reactor projects cannot replicate.

Commercialization & Traction

Meta's agreement includes a mechanism to prepay for power, providing Oklo with development capital at an early stage when the company has yet to generate revenues or build a commercially operating reactor. The Pike County site was formerly owned by the Department of Energy, reducing land acquisition complexity, and is close to Meta's existing data centre infrastructure in the region. Oklo went public via a SPAC merger in May 2024 and reached a market capitalisation of tens of billions of dollars in 2025, reflecting investor confidence in the Meta agreement and the broader advanced nuclear pipeline. The project is expected to create thousands of construction and long-term operations jobs and generate new local tax revenue for Pike County.

Scalability & Strategic Context

The Oklo Ohio Campus is the largest advanced nuclear project announced to date by a technology company, and its 1.2 GW scale would, if delivered, represent a meaningful contribution to PJM's clean firm capacity. The phased build-out — from first phase online by 2030 to full capacity by 2034 — is designed to validate the Aurora platform at increasing scale, with each phase informing the next. HALEU supply remains a constraint: the only current commercial vendors are in Russia and China, with U.S. domestic HALEU infrastructure still being developed. Oklo's fuel fabrication facility at INL, which received DOE approval of its Preliminary Documented Safety Analysis in late 2025, is the critical upstream dependency for the Aurora platform's commercial viability at Ohio scale and beyond.
