AtkinsRéalis to Submit Notice for CANDU Reactor Licensing
AtkinsRéalis Group Inc. (TSX: ATRL), a globally recognized engineering services and nuclear technology firm, has taken a significant step in the field of nuclear energy by formally notifying the U.S. Nuclear Regulatory Commission (NRC) of its intent to license its CANDU® reactor technology in the United States. This initiative is part of a broader strategy to address the escalating power demands driven by high energy consumers such as data centers and advanced manufacturing.
A Pioneering Move in Nuclear Energy
On June 24, 2026, AtkinsRéalis announced this pivotal filing, marking the beginning of a structured engagement process with the NRC. Ian L. Edwards, President and CEO of AtkinsRéalis, expressed optimism about this milestone, noting that it is crucial for contributing to U.S. energy security through reliable and cost-effective nuclear power solutions. He emphasized that the company, as the steward of CANDU technology, is well-equipped to support the U.S. in its ambitious energy goals.
The CANDU® reactor, an established platform worldwide with over 34 operational units and nearly 1,000 reactor-years of experience, positions AtkinsRéalis favorably in the nuclear sector. The Enhanced CANDU®6, a 700+ MW-class pressurized heavy water reactor, uniquely utilizes natural uranium fuel and is designed for online refueling, allowing for uninterrupted power generation.
Proven Track Record and Safety
CANDU reactors have proven their reliability through decades of operation across various countries, including Canada, Romania, Argentina, Korea, and China. Their design is fortified with two independent, fast-acting shutdown systems, which have consistently demonstrated exceptional operational safety and performance internationally.
Another compelling aspect of CANDU technology is its co-production of medical-grade isotopes essential for cancer treatment and medical sterilization globally. In fact, CANDU reactors in Canada are responsible for 50% of the world's supply of the essential Cobalt-60 isotope.
Engaging with U.S. Power Market
To facilitate the successful deployment of CANDU reactors, AtkinsRéalis is actively engaging U.S. utilities, state governments, and large-scale energy consumers, particularly hyperscale data center operators. The focus is on sites with existing nuclear infrastructure and favorable regulatory environments, aiming to minimize risks associated with siting and expedite project timelines.
Joe St. Julian, President of Nuclear at AtkinsRéalis, highlighted how CANDU reactors can reinforce U.S. energy independence by utilizing natural uranium without requiring enrichment. This approach not only reduces reliance on foreign enrichment services but also strengthens the domestic nuclear fuel supply chain, which is vital given today’s geopolitical climate.
The Future of CANDU Technology in the U.S.
AtkinsRéalis boasts a workforce of over 40,000 employees worldwide, with 7,000 specialists dedicated to its nuclear operations. They provide comprehensive services throughout the nuclear lifecycle, from construction and refurbishment to operational support and waste management. The Canadian nuclear supply chain includes over 250 companies, employing around 90,000 individuals, all contributing to a robust industry focused on sustainable energy.
As the company embarks on this licensing journey, expectations are high that CANDU reactors will play a crucial role in enhancing U.S. energy capacity. With commitment to innovation and a proven track record, AtkinsRéalis is poised to transform the landscape of nuclear energy in America and beyond. For more information, visit
