We stand at a pivotal moment in energy transition. The nuclear industry is tasked with a challenge that is both daunting and exhilarating: to triple global nuclear capacity by 2050. This means constructing hundreds of new reactors fi an ambitious target that will require not just technological innovation, but a rethinking of regulatory frameworks, supply chain integration and workforce development.

For nuclear to fulfil its potential in the energy transition, innovation must extend beyond reactor design to encompass the entire ecosystem of nuclear development. The UK is one of many nations that is already taking bold steps to enable this change. Early in 2024 the country launched its Civil Nuclear Roadmap and announced reforms designed to streamline regulatory processes and encourage international collaboration. Bold action now will determine whether nuclear can truly deliver on its promise as a cornerstone of the global energy transition.

Nuclear energy’s unique attributes make it indispensable in the journey to net zero and a versatile contributor to the low-carbon economy. It also represents an opportunity for economic growth. Nuclear new build projects are set to create thousands of jobs while revitalising domestic supply chains. However, scaling up to meet future energy needs will require significant investment in both infrastructure and regulatory support.

Ambitious targets for growth in nuclear generation will require a substantial acceleration in the pace of development fi far exceeding the timelines we’ve seen in the past. To put it in perspective, the construction of even a single reactor can currently take far more than a decade, and the industry also faces the challenge of scaling a supply chain that has seen limited activity for years.

Regulatory reform will be key to achieving this acceleration. Streamlining planning approvals, introducing more flexible financing mechanisms like the Regulated Asset Base (RAB) model, and adopting international standards for reactor design certification could dramatically reduce project timelines and costs. But regulatory reform and better decision making must go beyond the nuclear island if nuclear is to play its role in a low carbon future. 

Embracing supply chain innovation

The nuclear supply chain has been in a state of managed decline for decades. While global interest in nuclear energy is now surging, the industry must reckon with a stark reality: the infrastructure and expertise needed to meet ambitious targets have not been adequately sustained. Developing a robust supply chain that can handle the scale of demand is critical.

Decades of underinvestment and limited development have left critical gaps in infrastructure, expertise and manufacturing capacity. The industry now faces the monumental task of rebuilding its supply chain to meet unprecedented demand.

This isn’t just about ramping up production; it’s about rethinking how projects are delivered. One of the key challenges is transitioning from a reactive approach to a proactive one, where inefficiencies are addressed holistically. This means creating systems that don’t rely on single suppliers or outdated methodologies. 

Beyond technological innovation, a focus on collaboration and diversification is critical. Developers must ensure the supply chain is resilient by engaging multiple suppliers and leveraging expertise from consultancies and subject matter experts. This approach not only mitigates risk but also encourages competition and innovation within the supply chain, fostering a more dynamic and capable ecosystem.

Collaboration between regulators, industry stakeholders and supply chain partners can create a framework that balances safety, efficiency and growth

Rebuilding the nuclear supply chain is no small feat, but with the right combination of innovation, collaboration and strategic investment, the industry can position itself to deliver on its ambitious targets.

Beyond the nuclear island

While attention often centres on advanced reactors like Small Modular Reactors (SMRs), equal emphasis is needed on the systems supporting these technologies. Innovations inside and outside the nuclear island are pivotal for safety and operational resilience.

An example of one of the many areas that should be subject to regulatory reform is the fire safety sector. As reactors evolve to become more compact and efficient, so too must fire safety systems, for example. SMRs often feature integrated designs that reduce plant footprints but pose unique fire safety challenges. Traditional fire containment methods may not align seamlessly with these configurations, necessitating advanced solutions. However, innovations in materials science and engineering can enhance fire safety without adding unnecessary complexity. Lightweight, heat-resistant materials and real-time monitoring technologies offer dynamic fire management capabilities tailored to modern reactors. These advancements require a parallel evolution in supply chains, regulatory frameworks and workforce training to ensure their seamless integration.

Fire safety innovations must also extend beyond plant boundaries. Systems that integrate with external infrastructure, such as emergency responders and grid operations, enhance resilience and minimise the cascading effects of incidents. Robust data-sharing technologies can facilitate coordinated responses, safeguarding communities and grid reliability.

Progress in fire safety exemplifies how advancements in supporting systems amplify the benefits of new nuclear projects. Alongside improvements in grid integration and cooling systems, such innovations are vital to making nuclear a cornerstone of the low-carbon energy transition.

Building a diversified, resilient supply chain

The risks of relying on incumbent OEMs to drive supply chain development are clear and have plagued the nuclear sector for some time. A diversification of the traditional supply chain will be needed to avoid bottlenecks, limits on innovation and increased project vulnerability. Nuclear developers must cultivate a diversified supply chain that draws on skilled subject matter experts including those from outside of the traditional supply chain, to improve challenges found in today’s supply chain. 

When considering fire safety systems, this approach reduces risk while fostering innovation in critical areas such as fire safety and grid integration, while bringing in tried and tested methods, equipment and solutions proven in other high hazard sectors. Regulatory support for this collaborative model is essential to align contributions with nuclear safety standards.

Regulatory reform and supply chain development must go hand in hand. A streamlined, transparent regulatory environment not only builds confidence among suppliers but also accelerates the deployment of technologies critical to achieving net zero ambitions. Simultaneously, a robust and resilient supply chain enhances the industry’s ability to meet stringent regulatory standards, creating a virtuous cycle that supports the rapid expansion of nuclear energy.

By fostering collaboration between regulators, industry stakeholders and supply chain partners, nations can create a framework that balances safety, efficiency and growth. This alignment is essential to unlocking the full potential of nuclear energy, ensuring it not only plays a central role in the energy transition but also strengthens energy security.
