What ARC Clean Energy does
ARC Clean Technology Inc. is a private advanced nuclear reactor developer commercializing the ARC-100, a 100 MWe sodium-cooled fast reactor using uranium-zirconium metallic fuel. The technology is derived from EBR-II, which operated at Idaho National Laboratory for 30 years (1964-1994) and demonstrated passive safety through natural physics in 1986 loss-of-flow tests. Headquartered in Washington, DC with Canadian operations in Saint John, New Brunswick, the company was founded in 2006 and has 11-50 employees. The ARC-100 delivers 95% capacity factor baseload power with a 20-year fuel cycle, a 510°C sodium outlet temperature (expandable to 850°C) for industrial process heat, and a compact city-block footprint enabling co-location with data centers and industrial facilities.
The company targets four customer segments: AI data center operators needing 24/7 behind-the-meter baseload power, electrical grid utilities replacing retiring coal and gas capacity, heavy industry (steel, cement, petrochemicals) requiring high-temperature process heat, and medical isotope production (Mo-99, Ac-225, Co-60, I-131, Lu-177, Pb-212, Cu-67) as a byproduct of power generation. The business model centers on long-term power purchase agreements with bespoke project-based pricing, supplemented by potential dual-revenue from medical isotope sales. Distribution is exclusively direct enterprise sales, with strategic joint ventures supporting regional deployment.
ARC has raised approximately $66 million across multiple funding rounds since 2021, including a $30 million Series A in 2022 (Province of New Brunswick) and a Series B closed in December 2025 (IC Nuclear & Industry contributed $15 million; YEO Technology invested at a $60.4 million post-money valuation). The company has secured strategic partnerships with NB Power (Point Lepreau), Nucleon Energy (NuARC joint venture for Alberta), KHNP (global deployment), GE Vernova Hitachi, IHI Corporation, and Hatch. It is the only Generation IV aSMR in Canada to complete CNSC Vendor Design Review Phase II and has submitted a License to Prepare Site application. NRC pre-application engagement since 2020 includes 150+ technical documents and 9 formal meetings.

Revenue model
- Electricity Generation Sales: Power purchase agreements for 100 MWe baseload electricity delivery to data centers, utilities, and industrial facilities. 20-year fixed fuel cost locked at commissioning provides price certainty for customers.
- Medical Isotope Production: Production of Mo-99, Ac-225, Co-60, I-131, Lu-177, Pb-212, and Cu-67 as byproduct of normal power generation operations. Dual-purpose revenue stream with minimal marginal cost since reactor capital cost is justified by electricity revenue.
- Industrial Process Heat Sales: Direct thermal energy sales at 510°C sodium outlet temperature (up to 850°C with topping heat) for steel, cement, petrochemical, and chemical industries. Cogeneration capability splits thermal output between direct heat supply and power generation.

Product offeringCore offering
ARC Clean Energy (legally ARC Clean Technology Inc.) is commercializing the ARC-100, a 100 MWe Generation IV sodium-cooled fast reactor using uranium-zirconium metallic fuel. The reactor is the commercial evolution of the EBR-II, which operated for 30 years at Idaho National Laboratory, and is designed to deliver firm, dispatchable 24/7 baseload electricity, 510°C process heat for heavy industry, and medical isotopes as byproducts of normal operation. Customers include hyperscale data center operators, electrical utilities, and heavy industrial facilities.
Product overview
ARC Clean Technology offers a single unified product: the ARC-100 sodium-cooled fast reactor. This 100 MWe small modular reactor (SMR) is designed for multiple applications including AI data centers (dedicated behind-the-meter power), electrical grid (dispatchable baseload for 75,000 households), heavy industry (510°C thermal energy for steel, cement, and petrochemical processes), and medical isotope production (Mo-99, Ac-225, Co-60, I-131, Lu-177, Pb-212, Cu-67 as byproducts of normal operation). The reactor is factory-fabricated, modular, and scalable from 100MWe to 600MWe+ per site.
