Cardiff (The Wales Times) February 26, 2026 – The Welsh Government has pledged to ensure Wales maximises every opportunity from modern nuclear generation at Wylfa in North Wales, as announced by Cabinet Secretary for Economy, Energy and Planning, Rebecca Evans, during a speech at a Nuclear Industry Association event today. The event, held in Cardiff, spotlighted a pivotal year for the UK’s civil nuclear industry and received support from the Wales Nuclear Forum, with sponsorship from Rolls-Royce SMR, the firm designing the UK’s inaugural three small modular reactors (SMRs) at Wylfa. Evans emphasised Wales’ long-term backing for the project as a key low-carbon initiative poised to deliver enduring industrial benefits.

Rebecca Evans outlined the Welsh Government’s vision for Wales not only to host nuclear facilities but also to play a central role in their construction, maintenance, and supply chains. This commitment builds on years of support for nuclear development at Wylfa, positioning it as a cornerstone of low-carbon energy infrastructure. The announcement underscores a strategic push to harness nuclear advancements for economic growth across North Wales and beyond.

What Did Rebecca Evans Say in Her Speech?

As reported directly from the event coverage, Cabinet Secretary Rebecca Evans stated:

“The Welsh Government and I have supported new nuclear at Wylfa for many years – we regard it as a major low-carbon infrastructure project and as a long-term industrial opportunity.”

She further elaborated:

“We want Wales to reap all the benefits that modern nuclear can bring, and intend for Wales not only to host nuclear generation, but to help build it, maintain it and supply it for decades to come.”

These remarks, delivered at the Nuclear Industry Association gathering in Cardiff, reflect a consistent policy stance aimed at integrating nuclear energy into Wales’ sustainable development framework.

Evans’ speech highlighted the broader implications for job creation, skills development, and energy security. By framing Wylfa as more than a power site, she positioned it as a catalyst for industrial renaissance in a region with historical ties to energy projects. The event’s focus on a “monumental year” for UK civil nuclear underscores the timely nature of these declarations amid national pushes for net-zero goals.

Why Is Wylfa a Focus for Modern Nuclear in Wales?

Wylfa, located on Anglesey in North Wales, emerges as a prime site due to its established nuclear legacy and suitable infrastructure. The Welsh Government views modern nuclear generation here as pivotal for low-carbon electricity production, aligning with UK-wide decarbonisation efforts. Rolls-Royce SMR’s involvement in designing three small modular reactors marks a shift towards innovative, scalable technology that promises faster deployment and lower costs compared to traditional large-scale plants.

The site’s selection ties into Wales’ geography and energy needs, with proximity to population centres and grid connections facilitating efficient power distribution. Historical operations at Wylfa Newydd, previously planned but stalled, have paved the way for renewed momentum under SMR designs. This development positions North Wales at the forefront of Britain’s nuclear revival, potentially generating thousands of high-skilled jobs.

What Is the Proposed Manufacturing Facility in Deeside?

In a key announcement at the Cardiff event, Cabinet Secretary Rebecca Evans revealed that the Welsh Government is preparing a proposal for Rolls-Royce SMR to establish a modular manufacturing facility in Deeside, Flintshire. As per her direct statement:

“Deeside is recognised as an advanced manufacturing cluster with established heavy industry, logistics connectivity, a skilled workforce and supporting infrastructure, further strengthened by its designation within a £160 million investment zone.”

She added:

“An SMR factory in Deeside would not simply support one site – it would anchor a repeatable build programme and a long-term supply chain for many decades to come.”

Deeside’s credentials as a manufacturing hub stem from its industrial heritage, including aerospace and automotive sectors, bolstered by excellent transport links via road, rail, and proximity to ports. The £160 million investment zone designation enhances its appeal through tax incentives and infrastructure upgrades. This facility would produce SMR components, enabling modular construction that reduces on-site assembly time and costs, while fostering a domestic supply chain resilient to global disruptions.

How Does This Benefit Wales’ Economy and Energy Sector?

The initiative promises multifaceted economic gains, from direct employment in construction and operations to indirect jobs in supply chains. By localising manufacturing in Deeside, Wales could export nuclear expertise nationwide and internationally, mirroring successes in wind energy. Rebecca Evans’ vision extends to skills training, with partnerships likely involving local colleges and universities to upskill workers in advanced engineering.

Energy security bolsters the case, as SMRs offer reliable baseload power amid intermittent renewables. Low-carbon credentials support Wales’ 2035 clean power target, reducing reliance on fossil fuels. Long-term, this could stabilise energy prices and attract further investment, revitalising post-industrial communities in Flintshire and Anglesey.

What Role Does Rolls-Royce SMR Play?

Rolls-Royce SMR, sponsor of the Cardiff event, leads the design of the UK’s first three small modular reactors destined for Wylfa. Their factory-ready modules promise 470 megawatts per unit, with scalability for fleet deployment. The Deeside proposal aligns with their strategy for UK-based production, leveraging Wales’ industrial base.

Collaboration with the Welsh Government signals strong public-private synergy. Rolls-Royce SMR’s track record in defence and marine engineering instils confidence in delivery timelines, potentially operational by the early 2030s.

Who Supports This Nuclear Push?

The Wales Nuclear Forum co-supported the event, advocating for the sector’s growth. Industry bodies like the Nuclear Industry Association frame 2026 as transformative, with policy alignment from Westminster. Community backing in Anglesey, tempered by past consultations, remains crucial, with assurances on safety and decommissioning.

What Are the Environmental and Safety Considerations?

Modern SMRs prioritise passive safety systems, minimising meltdown risks through gravity-driven cooling. Wales’ stringent regulations ensure compliance, with the Office for Nuclear Regulation overseeing standards. Low-carbon output aids biodiversity goals, contrasting fossil alternatives.

How Does This Fit UK Nuclear Ambitions?

This aligns with Great Britain’s 24 gigawatts nuclear target by 2050, complementing Hinkley Point C and Sizewell. Wales’ contribution via Wylfa enhances national resilience. Deeside’s supply chain could serve multiple sites, amplifying impact.

What Challenges Lie Ahead?

Planning approvals, funding, and skilled labour shortages pose hurdles. Public engagement addresses concerns over waste and traffic. Geopolitical supply chain risks necessitate domestic focus, as in Deeside.

Broader Implications for Welsh Industry

Beyond energy, nuclear spurs innovation in materials and robotics. Investment zones like Deeside’s attract ancillary firms, boosting GDP. Rebecca Evans’ proactive stance positions Wales as a nuclear leader.
