ARC Clean Technology Secures Series B Funding to Advance Nuclear Reactor Commercialization

ARC Clean Technology announced the successful closing of its Series B financing round, attracting investors from energy, infrastructure, and technology sectors including Xplor Ventures, Hennessy Capital Group, Cleantech Ventures, Core Synergy and Banpu Ventures. The funding will advance commercialization programs for the ARC-100, a 100 MWe advanced sodium-cooled fast reactor, and support ongoing work with the U.S. Department of Energy (DOE) and collaboration with Korea Hydro & Nuclear Power (KHNP) for global deployment. James Wolf, newly appointed CEO, stated that the investment reflects confidence in the ARC-100's capability to deliver reliable, clean heat and power for energy-intensive industries and next-generation data centers.

The company's progress includes being a grant funding awardee of the US Department of Energy Advanced Reactor Demonstration Program to develop and deploy the ARC-100 in the United States. In Canada, ARC has been working with New Brunswick Power on a commercial demonstration at the Point Lepreau site, where a License to Prepare Site application was submitted to the Canadian Nuclear Safety Commission (CNSC) in 2023. In 2025, ARC successfully completed Phase 2 of the CNSC's rigorous Vendor Design Review process, making it the only advanced reactor technology in Canada to achieve both milestones. Additionally, ARC announced the formation of NuARC, a partnership with Calgary-based Nucleon Energy to develop and deploy the ARC-100 starting in Alberta, with potential site evaluations in progress.

ARC's simple advanced reactor design uses proven sodium-cooled fast reactor technology, generating interest from multiple jurisdictions and project developers seeking reliable, clean energy for AI data centers, industrial applications, and on-grid needs. The company's collaboration with strategic partner Hatch, which has worked closely with ARC since 2022, highlights the reactor's suitability for powering hyperscale data centers and heavy industry due to its high-temperature, zero-emission design. Amar Jolly, Managing Director of Power at Hatch, noted the significant progress toward deployment and expressed anticipation for continued partnership as ARC advances toward commercial deployment.

The financing enables ARC to accelerate deployment with partners in the United States, Canada, and internationally, addressing the growing demand for carbon-free power solutions. The ARC-100's modular design provides 100 megawatts of energy for electricity and industrial applications, leveraging technology from a 30-year prototype performance. This development comes as global energy needs evolve, particularly with the rapid expansion of AI infrastructure requiring substantial, reliable power sources. The Series B round's diverse investor base, including corporate venture capital, venture funds, strategic investors, and family offices, underscores broad market confidence in advanced small modular reactors as a viable clean energy solution.
