First binding commercial contract by a U.S. advanced reactor developer for Western commercial HALEU enrichment services represents a major milestone for the nuclear industry

LONDON, GB / ACCESS Newswire / September 15, 2025 / Today, Radiant and Urenco announced the signing of a first agreement for the supply of High-Assay Low-Enriched Uranium (HALEU) enrichment services to support the deployment of Radiant's Kaleidos microreactors.

This agreement is the first binding commercial contract by a U.S. advanced reactor developer for Western commercial HALEU enrichment services and represents a major milestone for the nuclear industry.

A signing event took place between Radiant and Urenco in London today ahead of the U.S. President's state visit to the UK.

Radiant Chief Nuclear Officer, Dr. Rita Baranwal, said:

"This announcement is a great example of the vital role the United States and United Kingdom jointly play in leading the advancement of the nuclear industry. It is also another step forward in our mission to build mass-produced nuclear reactors - an advancement which will require continued growth of the global supply chain."

Chief Executive Officer for Urenco, Boris Schucht, said:

"Today's announcement reflects the strong global leadership of the United States and the United Kingdom in supporting the deployment of the next generation of reactors and in expanding and strengthening the Western nuclear fuel supply chain.

"The close cooperation and partnership between the U.S. and the UK has and will continue to play a critical role in supporting the demonstration and deployment of advanced nuclear reactors to meet growing energy demands, including for the technology sector, and in strengthening energy security for both countries, as well for allied nations across the world.

"This deal represents a very positive step for the development of small modular reactors (SMRs) in the industry."

U.S. Secretary of Energy, Chris Wright, said:

"With President Trump's leadership, the United States is ushering in a true nuclear renaissance - harnessing the power of commercial nuclear to meet rising energy demand and fuel the AI revolution. Meeting this demand will require strong partnerships with our allies around the world and robust collaboration with private sector innovators. Today's commercial deals set up a framework to unleash commercial access in both the U.S. and UK, enhancing global energy security, strengthening U.S. energy dominance, and securing nuclear supply chains across the Atlantic."

UK Energy Secretary, Ed Miliband, said:

"British business will thrive under the UK-US partnership on nuclear, and this deal between Urenco and Radiant demonstrates just that.

"By working in lockstep with the US, we will reap the benefits of this golden age of nuclear, powering British homes with clean, homegrown energy, delivering well-paid skilled jobs and getting energy bills down for good."
