Pegasus: scalable, versatile and engineered for the next era of nuclear fuel transport
As the new age of nuclear power emerges, next-generation reactors demand modern fuels that can be moved safely, reliably and at scale. Meeting that challenge sits at the heart of Pegasus, the package leading the way in future fuel transport.
PEGASUS, THE NEW ADVANCED transport package developed by Nuclear Transport Solutions (NTS), is set to redefine how the global industry moves next generation nuclear fuels. Its design reflects a future in which fuel types will diversify, reactor technologies will advance, and the energy system will demand ever-greater reliability. Built for scalability, versatility and engineered assurance,
Pegasus is positioned to become a foundational element of the supply chains needed to support the future of nuclear energy. Such is the uniqueness of Pegasus’ design, Westinghouse recently signed a Heads of Terms agreement with NTS to share information between the companies to accelerate its development for deployment. The signing of the agreement marks a significant moment
in UK–US collaboration on advanced nuclear fuel transport. The partnership formalises how the two organisations will share engineering expertise, regulatory insight and specialist knowledge to accelerate the development of Pegasus for deployment on both sides of the Atlantic. Pegasus has been designed as a world leading transport solution capable of supporting a diverse range of advanced fuel types, including HALEU, UF6 and TRISO, reflecting the reality that future reactor programmes will not rely on a single fuel form. This versatility, combined with NTS’s long operational history and global reputation for safe, secure and reliable nuclear movements, provides a strong foundation for scaling future fuel supply chains. As part of the Nuclear Decommissioning Authority
group, NTS benefits from deep technical capability, further strengthened by the UK government’s 2024 award of £10.5 million to develop national HALEU transport infrastructure. The agreement with Westinghouse sits within a wider
shared ambition between the UK and the United States to enhance energy security, accelerate new nuclear deployment and build resilient, modern fuel logistics. It represents an important milestone in the collective effort to ensure that advanced reactors are supported by transport systems that meet the highest standards of safety, assurance and long- term strategic value.
A scalable transport platform for a rapidly evolving sector Scalability is central to Pegasus. The design anticipates a future where fuel volumes may increase, reactor types may diversify and supply chains may span multiple countries. Rather than a single-purpose container, Pegasus is an adaptable platform engineered to accommodate a range of payload configurations. By adopting a modular internal architecture, NTS has created a system that can support new fuel types – Pegasus can transport front-end HALEU products

in different forms, such as uranium oxide, uranium metal and uranium hexafluoride, it can also be configured to transport finished TRISO fuel. Sean Perry, lead technical designer at NTS, said:
“Pegasus is designed to be a versatile solution to the new generation of nuclear fuel. It can transport HALEU in all forms as well as the other fuels being explored for the incoming nuclear reactors.” This approach gives operators and fuel developers
confidence that their evolving requirements can be met by a single, certifiable transport solution. It also reduces the engineering burden on future reactor programmes, which can align their fuel handling frameworks directly with an established package already progressing through the regulatory process.
Versatility designed into the core The versatility of Pegasus lies not only in what it can carry, but in how it has been designed to operate across multiple regulatory areas, modes of transport and security environments. NTS has used decades of practical experience in international nuclear logistics to shape the package’s configuration, handling characteristics and operational safety capabilities. Its design also supports deployment across multimodal routes, including road and international shipping. By combining scalability, versatility and rigorous engineering, Pegasus is more than a transport package: it is a strategic enabler for the next generation of nuclear energy. ■
