Can nuclear unlock the UK’s clean energy transformation?

The UK’s energy transition has entered a new phase. The challenge is no longer only how to decarbonise power generation. It’s also about how to build an energy system capable of supporting long-term economic growth, industrial competitiveness and energy security simultaneously. 

As electricity demand accelerates, the need for reliable, low-carbon baseload power is becoming increasingly urgent. This is driven by AI-enabled data centres, electrified manufacturing, hydrogen production and gigafactories. Nuclear energy is uniquely positioned to meet this challenge. 

“This is particularly true for small modular reactors (SMRs).”  

They can support large-scale nuclear power with faster deployment timelines, flexibile sites and a repeatable delivery model.  

Delivering a new generation of nuclear infrastructure at the needed pace and scale will take more than policy ambition. It will require a fundamentally different approach to programme delivery. 

The opportunity is significant, but so is the delivery challenge 

The UK has an opportunity to establish itself as a global leader in nuclear delivery. Continued investment in programmes such as Hinkley Point C, Sizewell C, fusion and SMRs is helping establish the foundations for a long-term nuclear delivery pipeline.  

Yet the scale of ambition now being discussed can’t be delivered through traditional infrastructure models alone. 

Historically, major nuclear programmes were treated as standalone megaprojects. They often used bespoke designs, fragmented supply chains and delivery structures. These factors limited repeatability and learning transfer between projects.  

“While these programmes have developed world-class expertise and maintained exceptional safety standards, they’ve also highlighted the complexity of delivering highly regulated infrastructure at scale.”   

Additionally, siting a nuclear reactor has historically been complex and constrained, whereas SMRs bring a more flexible and agile approach.  

The UK’s next phase of its nuclear journey needs a more integrated, industrialised delivery model. It should improve predictability, accelerate deployment and create long-term value across the entire programme lifecycle. 

Moving from project delivery to programme delivery 

One of the biggest shifts requires a move away from viewing nuclear projects as individual assets. They must be treated as part of a coordinated national programme. 

This shift requires the sector to move beyond traditional project-by-project delivery. 

Creating repeatability across design, governance and supply chains will be essential to improving delivery certainty. This will accelerate deployment and reduce long-term cost and risk across future nuclear programmes. This will: 

• standardise delivery approaches 
• strengthen programme-wide governance 
• create more resilient supply chains 
• enable lessons learnt to transfer rapidly between projects. 

In practice, this means establishing programme-wide standards from the start. This includes aligned governance, shared delivery control and common procurement and supply chain approaches.  

Early contractor involvement and digital programme management tools can help, along with long-term visibility of the project pipeline to improve coordination across multiple delivery partners. They also help transfer lessons learnt more effectively between projects. 

Other sectors have already demonstrated the value of this approach. Offshore wind programmes in the North Sea and hyperscale data centres have successfully used standardised designs, modular construction and repeatable supply chain models to improve delivery speed and cost certainty at scale. 

“For nuclear, adopting similar principles will be essential if the UK is to scale delivery successfully over the coming decades.”  

This will require greater adoption of modern methods of construction, increased off-site manufacturing and innovative logistics. There must also be stronger integration between designers, manufacturers and delivery teams in a variety of locations.  

Embedding design for manufacture and assembly (DFMA) principals earlier in the lifecycle can help reduce on-site complexity, improve quality assurance and create more predictable delivery outcomes. This will become increasingly important as SMR programmes move towards fleet deployment.  

Here, repeatability and transferability of lessons learnt, against a maturing suite of data, will directly influence delivery performance that needs to continually improve. 

Supply chains to evolve alongside ambition 

Evolving supply chains will require earlier and more strategic collaboration between clients, government and industry partners. Providing suppliers with long-term visibility of future demand can help unlock investment in manufacturing capability, workforce development and regional capacity.  

“At the same time, commercial models need to encourage partnership behaviours, moving away from short-term transactional contracting.”  

They must focus on arrangements that support shared planning, innovation and risk management across the programme lifecycle. 

This is particularly important for emerging technologies such as SMRs, where repeatability and manufacturing-led delivery will depend on strong integration between developers, suppliers and programme partners from the earliest stages.  

SMRs could also create opportunities for a more manufacturing-led nuclear supply chain in the UK, supporting regional industrial growth and long-term capability development.  

It’s important to note the wider positive impact SMR technology can bring in terms of the socio-economic impact. This isn’t just about building a skilled workforce for the sector. It also supports regeneration in the areas where the sites will be located. 

The role of the intelligent programme manager  

As nuclear programmes become bigger and more interconnected and increasingly portfolio-driven, the role of the intelligent client becomes even more important. 

Successfully delivering complex infrastructure at scale requires organisations to maintain clear programme oversight, integrated governance and strong interface management across multiple stakeholders and supply chains. 

Digital programme controls, advanced planning capability, data-led decision-making and integrated commercial strategies will all play a critical role in improving certainty and enabling faster, more informed decisions. 

“At the same time, organisations must balance innovation with delivery discipline.” 

Maintaining design maturity, controlling scope change and establishing clear programme standards early will be fundamental to improving long-term outcomes. 

These aren’t simply technical challenges. They’re delivery and organisational challenges that require the right capability, leadership and strategic alignment across the full programme ecosystem. 

Creating long-term value 

The impact of nuclear investment extends far beyond power generation. A successful programme can stimulate regional growth, create high‑value jobs, attract inward investment and strengthen domestic industrial capability across the UK.  

By building long‑term supply chain capacity and investing in future skills, the sector can generate lasting economic and social value. This will position the UK as a global exporter of nuclear expertise and strengthen programme delivery capability.  

“This is an increasingly important advantage as countries accelerate investment in clean energy infrastructure and compete for specialist skills.”  

Against this backdrop, the strategic case for nuclear is becoming clearer. The priority now is how the sector delivers at the scale, pace and consistency required to meet future demand. Success will depend on establishing delivery models that are repeatable, investable and capable of supporting sustained industrial growth.  

SMRs offer a major chance to support this shift, but reaching their full potential needs a more industrial approach. It also needs stronger programme integration and effective supply chain coordination. 

Those organisations that combine technical excellence with scalable delivery and integrated leadership will not only strengthen the UK’s energy system but also help define how complex infrastructure programmes are delivered globally. 

SMRs offer one of the clearest opportunities to industrialise nuclear delivery in the UK. But their success depends on delivery models that are scalable, repeatable and investable over the long term.
