The UK government has selected the Wylfa site in North Wales as the location for the country’s first small modular reactor (SMR) power plant. According to calculations, the new plant will generate enough electricity for the equivalent of about three million homes, enhancing the nuclear generation’s contribution to the nation’s climate and energy goals. The project will be carried out by the state-owned company Great British Energy-Nuclear (GBE-N) using UK-developed Rolls-Royce SMR reactors-subject to final contract agreements.
“The announcement concerning Wylfa represents the first step in a 100-year commitment to clean energy, innovation, and partnership with the local community,” said Rolls-Royce SMR CEO Chris Chuter.
The main feature of this approach is modularity: station elements are to be delivered on-site for assembly. Unlike large traditional nuclear power plants, which are almost entirely built on location, this setup aims to simplify and expedite construction, reduce costs, and avoid the lengthy delays characteristic of large projects like Hinkley Point C.
Each Rolls-Royce SMR reactor is designed to produce 470 megawatts of low-carbon electricity. For comparison, this is equivalent to more than 150 land-based wind turbines of similar total power output. The initial phase of the project involves installing three such modules, and according to GBE-N estimates, the Wylfa site could eventually accommodate up to eight small reactors. Wylfa has a nuclear history dating back to the 1960s, and the new project is set to restore the region’s role as a major nuclear energy center. It is expected that at the peak of construction, the station will create up to 3,000 jobs.
The SMR program is supported by government investments exceeding $3 billion in the development of small modular technologies in the country. According to plans, GBE-N will begin active site work in 2026. The goal is to commission the SMRs and connect them to the grid by the mid-2030s. The government emphasizes that the current decision “corrects past failures” to strengthen energy independence and develop a domestic technological base in the nuclear sector.
The Wylfa project is part of a broader strategy. The UK is advancing the export potential of its SMRs and has already signed a civil nuclear cooperation agreement with the Czech Republic, following a partnership between Rolls-Royce SMR and the Czech state company CEZ. In parallel, the government has tasked GBE-N with identifying potential sites for a future large nuclear power plant by the fall of 2026, which is estimated to supply electricity to up to six million homes.
Recent advancements in the UK’s SMR strategies include developing international collaborations aimed at sharing technical expertise and strengthening supply chains, as well as increased research into next-generation nuclear reactors. The UK government continues to prioritize nuclear power within its strategic energy independence framework, factoring SMRs as crucial components in reducing carbon footprints and securing reliable energy sources for the future.
