The agreement with Radiant is the first binding commercial contract by a U.S. advanced reactor developer for Western HALEU enrichment services.
Our services will support Radiant to deploy its Kaleidos model microreactor.
Urenco and Radiant took part in a signing event at the US Embassy in London on Monday, September 15, ahead of the U.S. President’s state visit to the UK.
We were part of a wider government announcement on nuclear energy between the two countries, which you can read here.
Urenco Chief Executive, 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.”
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.”
