UK’s small modular reactors in Wales

by Simon Foulds

The Prime Minister has confirmed that Wylfa on Anglesey will host the UK’s first small modular nuclear reactors (SMRs), marking a major milestone in the nation’s clean energy strategy and the future of nuclear infrastructure. The decision sets the stage for thousands of skilled jobs, billions of pounds in investment, and a new generation of low-carbon energy capacity designed to strengthen the UK’s energy security and industrial resilience.

The project, led by publicly owned Great British Energy-Nuclear (GBE-N) and designed by Rolls-Royce SMR, will make Wylfa the focal point of the UK’s next phase of nuclear development. North Wales will become a hub of technological innovation and digital construction expertise, showcasing how advanced engineering, modular design, and local capability can deliver critical national infrastructure at scale.

A new chapter for North Wales’ nuclear heritage

Sitting on the North Wales coast, Wylfa has a long history of nuclear excellence dating back to the 1960s. The confirmation that it will now host the UK’s first SMR power station signals the revival of that legacy. The project is expected to support up to 3,000 jobs at peak construction and deliver billions of pounds in infrastructure investment extending into the mid-2030s.

Backed by over £2.5 billion in government funding, the initiative forms part of a broader industrial strategy designed to boost clean energy investment, modernise local economies and re-establish Britain’s global leadership in nuclear technology. It also complements other regional initiatives such as the Anglesey Freeport, the North Wales Investment Zone, and planned upgrades to the North Wales Mainline rail corridor, all aimed at supporting long-term regional growth and connectivity.

Delivering the UK’s clean energy mission

The small modular reactors to be built at Wylfa will deliver up to 1.5GW of low-carbon electricity, enough to power approximately three million homes. These reactors are smaller, faster to build, and more cost-effective than traditional large-scale nuclear plants. Their modular design allows for precision manufacturing and digital integration throughout the construction process, driving efficiencies, improving safety, and providing a platform for innovation across the supply chain.

For the digital construction sector, this marks a major opportunity to apply Building Information Modelling (BIM), advanced digital twins, and data-driven asset management to nuclear infrastructure. By embedding digital technologies at every stage, from design through to operation, the Wylfa SMR programme can set a new standard for how the UK delivers complex, safety-critical energy projects.

The SMR initiative aligns with the government’s ambition to make Britain a clean energy superpower, providing home-grown energy that supports the NHS, national security and British industry. With strong public backing through Great British Energy-Nuclear, the project will give the British people a direct stake in a sovereign energy technology with global export potential.

Building a modern industrial base

The Wylfa announcement is part of a broader nuclear revival. Alongside ongoing construction at Hinkley Point C and the newly confirmed Sizewell C, the government is advancing plans for future large-scale nuclear sites, with GBE-N tasked to identify potential locations across the UK by 2026. Together, these projects will play a central role in delivering secure, affordable, and low-carbon power for decades to come.

The government’s latest energy strategy forecasts 400,000 new clean energy jobs by 2030, including 15,000 in Wales alone. Trades such as welding, electrical installation, and precision engineering are in growing demand as part of the nuclear and renewables supply chain. The first phase of construction at Wylfa is expected to begin in 2026, with three SMR units initially planned and the potential for up to eight in the longer term.

Strengthening partnerships and export potential

The UK’s SMR programme also carries significant international potential. The government has recently signed agreements with the United States to streamline cross-border nuclear regulation and accelerate project delivery. Rolls-Royce SMR has also partnered with Czech energy company ČEZ, which has taken a 20% stake in SMR development, positioning the UK as a leading exporter of small modular reactor technology.

GBE-N, which also owns the former Oldbury nuclear site in Gloucestershire, is exploring opportunities for further deployment of SMRs and advanced modular reactors. The goal is to develop a fleet-based approach to new nuclear capacity, driving standardisation, reducing costs, and ensuring the UK builds long-term resilience in domestic energy generation.

A platform for future growth

Simon Bowen, Chair of Great British Energy-Nuclear, described the Wylfa announcement as a “historic moment” for UK energy infrastructure: “These first SMRs at Wylfa will lay the groundwork for a fleet-based approach to nuclear development, strengthening the UK’s energy independence and bringing long-term investment to the local economy. Wylfa has a proud history of nuclear excellence, and we’re excited to build on that foundation to deliver jobs, training, and low-carbon energy for generations to come.”

GBE-N has committed to close engagement with local communities and stakeholders to ensure that development proceeds responsibly and transparently. The project is expected to deliver lasting social and economic value, while supporting the UK’s net zero targets and clean growth ambitions.

A turning point for the UK’s energy future

The decision to bring small modular reactors to Anglesey signals a turning point in the UK’s approach to energy infrastructure and regional development. It represents not only a commitment to clean energy and energy independence but also a broader strategy to revitalise local economies through advanced manufacturing, digital construction, and long-term skills investment.

As the UK enters what many are calling a new ‘golden age of nuclear’, Wylfa could be the cornerstone of that transformation. This project connects innovation, sustainability, and national renewal in one of the most ambitious infrastructure programmes of the decade.
