- Programme of 14 Small Modular Nuclear Reactors could accelerate UK new nuclear and power almost eight million UK homes
- Project represents Britain’s largest privately-led nuclear investment
LONDON, July 2, 2026 /PRNewswire/ — SGE, a European Small Modular Reactor (SMR) development and investment platform, yesterday announced its plans to build fourteen GE Vernova Hitachi BWRX-300 Small Modular Reactors on three sites in the UK. The deployment team includes SGE, GE Vernova Hitachi Nuclear Energy, Samsung C&T, Laing O’Rourke, Aecon Group Inc., Google Cloud, Fermi Development, Etara and an experienced nuclear operator.
The company has submitted an application under the UK’s Advanced Nuclear Framework (ANF) to develop a combined 4.2GW fleet which could deliver enough clean power for 11% of UK power demand or equivalent to an estimated almost eight million homes for at least sixty years. To support this ambition, SGE has established SGE SMR UK Limited as its dedicated UK-based project vehicle.
SGE’s proposal reflects a fleet-based development model, centred on repeatable deployment at scale. The project is targeting three multi-unit sites, the first to host six BWRX-300 units, with two further sites to follow in quick succession. In total, the programme represents a significant addition to the UK’s future nuclear capacity and supports the country’s long-term energy security, clean power and industrial growth ambitions.
The UK project builds on significant regulatory groundwork already in place for the BWRX-300, a tenth generation, proven technology that draws on the experience of 67 successful reactor deployments. The technology is under licensed construction in Canada and is on schedule to be the first SMR to operate in the OECD. In December 2025, the BWRX-300 successfully completed Step 2 of the UK’s Generic Design Assessment.
The partnership brings together proven reactor technology, significant project development experience, industrial capability and supply chain expertise and financing structure experience to support the deployment of the BWRX-300 in the UK. SGE is presenting a privately financed, commercially-led investment, supported by strong delivery partners. SGE plans to deploy under a Contract for Difference framework with National Wealth Fund engagement, meaning there will be no charges to consumers prior to operations.
Michał Sołowow, Founder of SGE, said: “We are focused on delivering efficient, safe, affordable, and clean nuclear energy power at fleet scale. The UK is home to one of the world’s most experienced nuclear workforce and the British Government has provided a clear path to market with the Advanced Nuclear Framework. Because of this, I am confident we will set a new standard for nuclear development by combining our disruptive business model with the BWRX-300’s tenth generation proven technology. We will rely strongly on the UK supply chain; it is a critical element for our project. Our project will create a distinct competitive advantage for UK economy.”
Rafał Kasprów, CEO of SGE, said: “The submission of our application under the Advanced Nuclear Framework marks a major milestone in our ambition to develop a fleet of BWRX-300 small modular reactors across the UK and the European Union. The United Kingdom is one of Europe’s most important and capable nuclear markets, with a highly skilled workforce, a strong industrial base, and a strategic need to lead the next generation of nuclear deployment. With a clear requirement for substantial new nuclear capacity over the coming decades, we believe our approach can make a meaningful contribution at scale. Standardisation, repetition, modularisation, and a fleet deployment strategy are the most effective ways to deliver new nuclear projects successfully, reducing costs, construction risk, and delivery times. We are committed to working with UK partners to provide secure, affordable, and clean electricity to millions of British households for generations to come.”
Jason Cooper, CEO of GE Vernova Hitachi Nuclear Energy, said: “SGE’s vision reflects the growing momentum behind new nuclear across Europe and the critical role SMRs can play in strengthening energy security while delivering reliable, lower-carbon electricity. With construction already underway at the Darlington New Nuclear Project in Ontario, Canada, the first commercial-scale SMR under construction in the Western world, the BWRX-300 offers the confidence that comes from real project execution. We are proud to support SGE as they pursue this important opportunity in the UK.”
John O’Connor, Group Commercial Director of Laing O’Rourke, said: “Laing O’Rourke brings the power of its nuclear experience and pioneering industrialised construction methods to the development of Small Modular Reactors, like this programme, of which we are pleased to play a part. We are applying lessons learned from the use of advanced manufacturing in the construction of large-scale and other complex infrastructure to boost safety and certainty for our partners and clients.”
Aaron Johnson, Senior Vice President, Nuclear, Aecon Group Inc., said: “Aecon is proud to serve as a leading partner on Ontario Power Generation’s Darlington New Nuclear Project, supporting the first-of-a-kind BWRX-300 deployment in Canada. Drawing on deep expertise in construction management, advanced automation, fabrication, and modularization, Aecon is helping to drive meaningful improvements in safety, quality, schedule certainty, and cost efficiency. Early involvement in this landmark project positions Aecon to leverage first-of-a-kind experience and tailor proven approaches for SGE in the UK and in other international markets. We are building capabilities and insights that will enable us to support efficient and scalable deployment across North America and in global markets, including the UK.”
SGE anticipates this project will enter the Advanced Nuclear Pipeline in November 2026, with site selection and government support scheme negotiations completed in the first half of 2027; after which major investment, site preparation and licensing work would begin within approximately a year, with first commercial operation of the first unit targeted for 2034.
