Left: Rolls-Royce’s SMR programme has received an initial commitment for three reactors
from component manufacturers to those who specialise in digital engineering. But, beyond these flagship initiatives, future visibility remains limited. Suppliers are unlikely to commit to large-scale investments for projects that may not materialise for another decade. While modest capacity increases may be feasible, significant scaling demands a critical mass of orders and a clearly articulated roadmap encompassing SMRs, large-scale reactors, and fusion. Without this, the economic case for supply chain investment remains in question.
Consistency is key to supply chain success The UK’s nuclear policy has historically been characterised by a stop-start approach, which has undermined confidence and continuity in the supply chain. To reverse this trend, a clear and predictable cadence of project announcements is needed. More important than fixed targets is the regularity of opportunity – a steady drumbeat of projects that allows suppliers to plan, invest, and grow with confidence. A well-defined civil nuclear roadmap, underpinned by the
government recommitting to the 24 GW target, must outline the next steps. This includes clarity on where Rolls-Royce SMRs will be built, how future awards will be structured, and what role international vendors will play. Modularisation holds significant promise, but its benefits will only be realised through optimisation and standardisation – both of which require long-term planning and coordination.
Innovation beyond technology Innovation in the nuclear sector must extend beyond reactor design. Market structures, skills development, and regulatory frameworks all require modernisation. The UK can draw valuable lessons from sectors such as aerospace and automotive, in adopting lean manufacturing, digital integration, and supply chain agility. Reducing design complexity and avoiding bespoke, one-off solutions will be critical to building a resilient and scalable supply chain. A dynamic, standardised approach to SMR deployment will enable broader participation and reduce barriers to entry for suppliers. When designs are standardised, significant time, cost, and design savings can be achieved. This standardisation also fosters a more competitive and dynamic supplier environment. New entrants can more easily participate, offering more cost-effective solutions. In contrast, bespoke and highly complex designs tend to concentrate supply within a narrow group of providers, limiting flexibility and scalability. Moreover, a coordinated approach to standardisation can
expand the supply chain’s overall capacity without requiring each individual supplier to scale up independently. Simply broadening the pool of qualified suppliers increases national capacity and resilience. To fully realise this
opportunity, the UK must prioritise not just technological innovation, but also systemic innovation in how nuclear projects are designed, procured, and delivered.
Regulatory reform as an enabler The regulatory environment must evolve to support innovation while maintaining the highest safety standards. By collaborating more closely with industry and subject matter experts, the UK’s regulator’s pro-innovation stance can be realised. The British regulatory system, while robust, operates differently from many international counterparts, which can introduce delays, particularly when evaluating technologies not previously deployed in the UK. For example, the UK has never built a boiling water
reactor (BWR), which may have influenced the government’s decision to prioritise proven technologies like pressurised water reactors (PWRs) for early SMR deployment. While this de-risks delivery, it also highlights the need for more agile regulatory processes. GE Hitachi’s BWR-based SMR has already been approved in Canada – a country with a long-standing, highly qualified nuclear regulatory framework. This raises the question: if a design is approved by a credible international regulator, can the UK adopt a translational regulatory approach to accelerate its own approval process? Efforts are underway to explore such harmonisation, but
more must be done to formalise pathways for recognising international certifications and accepting components manufactured for use in other regulatory environments. This would not only reduce duplication but also enable a broader, more flexible supply chain. Ultimately, reform should focus on enabling adaptive
licensing processes, harmonising international standards, and facilitating the deployment of novel technologies without compromising safety. Bridging the gap between the regulator’s openness to innovation and the industry’s need for risk mitigation will require coordinated action across all stakeholders. A clear mechanism is needed to translate regulatory flexibility into tangible supply chain opportunities, ensuring that innovation is not just permitted, but actively enabled.
Looking ahead The UK is now in a strong position, politically, financially, and technologically, to lead in the next generation of nuclear energy. With a clear commitment to SMRs and a growing appetite for innovation, the country has the tools to transform its energy landscape and industrial base. This is a moment of strategic opportunity. With the right
follow-through, clear policy signals, regulatory reform, and industrial coordination, the UK can not only meet its energy goals but also lay the foundation for a new era of economic and technological leadership. ■
