Nuclear Transport Solutions (NTS) and US nuclear technology giant Westinghouse have signed a major new strategic agreement that strengthens UK–US cooperation in clean energy and nuclear innovation. The partnership will see both companies work together on Pegasus, a groundbreaking transport package designed to safely move the next generation of nuclear fuel.
The agreement was signed at the British Embassy in Washington DC during a high-profile event celebrating the shared commitment of the UK and the United States to advancing nuclear power. For many in the diaspora watching from abroad, the deal highlights how Britain continues to play a central role in shaping the future of global energy security.
Pegasus is being developed as the world’s leading transport solution for High Assay Low Enriched Uranium, known as HALEU. This advanced fuel is expected to power many next-generation nuclear reactors, which are seen as vital to delivering low-carbon, homegrown energy while supporting fast-growing technologies such as artificial intelligence.
By formalising technical cooperation between NTS and Westinghouse, the agreement allows both sides to share safety expertise, engineering knowledge and regulatory insight. This collaboration is designed to speed up the development of Pegasus while ensuring the highest international standards for fuel handling and transport are met in both countries.
Ben Whittard, Co-CEO of Nuclear Transport Solutions, said the partnership places the UK at the heart of the global nuclear future. He explained that the rapid growth of AI and digital infrastructure has increased demand for reliable, ultra-low carbon energy, making nuclear power more important than ever.
NTS brings more than 50 years of international experience to the partnership and is widely recognised as a trusted leader in secure nuclear transport. In 2024, the UK government awarded the company £10.5 million to lead the development of Britain’s HALEU transport capability. As part of the Nuclear Decommissioning Authority, NTS works closely with government and some of the UK’s most respected nuclear experts.
Sophie Lemaire, Interim Co-President of Westinghouse Nuclear Fuel, described the agreement as a crucial step in making HALEU fuel available across both the US and the UK. She said the collaboration would help unlock new opportunities for advanced nuclear projects on both sides of the Atlantic.
The deal also forms part of what officials describe as a new “golden age” of UK–US nuclear cooperation. It supports wider ambitions to expand clean energy generation, reduce dependence on Russian nuclear fuel and strengthen resilient supply chains among allied nations.
UK Minister for Nuclear, Lord Vallance, said developing domestic capability to produce and transport advanced nuclear fuel is critical for Britain’s long-term energy security. He added that the agreement also opens export opportunities that could grow the UK economy while helping allies build reliable energy systems.
David Peattie, Group CEO of the Nuclear Decommissioning Authority, said Pegasus represents a transformative step in advancing the UK’s clean energy ambitions. He noted that the project reinforces Britain’s position as a world leader in nuclear innovation while supporting global decarbonisation goals.
From a diplomatic perspective, the British Embassy in Washington highlighted the partnership as a clear sign that UK–US cooperation on nuclear energy is moving from ambition to delivery. Chargé d’Affaires James Roscoe said the deal brings British and American innovators closer together on engineering excellence, safety standards and regulatory understanding.
For the global diaspora following developments in energy, technology and investment, the NTS–Westinghouse agreement underlines how the UK continues to shape international solutions to climate change, energy security and future economic growth.
