ARC Clean Technology ("ARC"), a developer of advanced small modular reactors (aSMRs), announced the successful closing of its Series B financing round. The round attracted a diverse group of new and existing investors from the energy, infrastructure, and technology sectors, including the corporate venture capital arm of a major energy company, multiple venture capital funds, strategic investors, existing investors, and large family offices. Participants include Xplor Ventures, Hennessy Capital Group, Cleantech Ventures, Core Synergy, and Banpu Ventures.
The proceeds will be used to advance commercialization programs for the ARC-100, a 100 MWe advanced sodium-cooled fast reactor. The funding will support ARC's ongoing work with the U.S. Department of Energy (DOE), its collaboration agreement with Korea Hydro & Nuclear Power (KHNP) for global aSMR fleet deployment, and continuation of its Canadian project development supported by strategic partner Hatch.
"Hatch has been working closely with ARC since 2022, and we are pleased to see the significant progress the company has made toward deploying the ARC-100," said Amar Jolly, Managing Director, Power at Hatch. "Its high-temperature, zero-emission design is ideally suited to power hyperscale data centers and heavy industry, and we look forward to continuing our partnership as ARC advances toward commercial deployment."
As the company moves into the next phase of commercialization, James Wolf has been appointed CEO, while Bob Braun will continue to lead ARC operations in Canada. "This investment reflects strong confidence in ARC's progress and the capability of the ARC-100 to deliver reliable, clean heat and power for energy-intensive industries and next-generation data centers," said James Wolf, CEO of ARC Clean Technology. "The financing enables us to accelerate our deployment with our partners in the United States, Canada, and internationally."
ARC's simple advanced reactor design using proven sodium-cooled fast reactor technology, combined with recent commercialization milestones, is generating strong interest from multiple jurisdictions and project developers looking to aSMR technology for reliable, clean energy to support AI data centers, as well as industrial and on-grid applications. In the United States, ARC is a grant funding awardee of the DOE's Advanced Reactor Demonstration Program to develop and deploy the ARC-100. In Canada, ARC has been working with New Brunswick Power on a commercial demonstration of the ARC-100 at the Point Lepreau site. In 2023, New Brunswick Power submitted a License to Prepare Site application to the Canadian Nuclear Safety Commission (CNSC) for the ARC-100 project, and in 2025 ARC successfully completed Phase 2 of the CNSC's rigorous Vendor Design Review process. ARC is the only advanced reactor technology in Canada to have achieved both milestones. In 2025, ARC announced the formation of NuARC, a partnership entity with Calgary-based Nucleon Energy to develop and deploy the ARC-100 starting in Alberta, Canada, with evaluation of potential sites in progress.
The implications of this announcement are significant for the clean energy sector. The successful Series B financing indicates strong investor confidence in ARC's technology and its potential to provide reliable, carbon-free power for energy-intensive applications such as AI data centers and heavy industry. With regulatory milestones achieved in Canada and ongoing collaboration with the DOE, ARC is positioned to advance toward commercial deployment, potentially contributing to global efforts to decarbonize power generation.
