NuScale in the UK

NuScale Power in UK

NuScale Power is changing the power that changes the world. To do so, we’re expanding our reach across the globe. We’re exploring potential opportunities to enter into partnerships to bring our small modular reactor to the UK market. The UK has a strong nuclear heritage and has for many decades been a leader in developing new technologies and bringing them to the market. Powered by the NuScale Power Module™, our VOYGR™ power plants can help the UK meet its energy targets through the generation of smarter, cleaner, safer, and cost-competitive electricity.

The vision is to see NuScale Power Modules being built in the UK for use in the domestic and European market.

Compatibility with UK Energy Policy

NuScale VOYGR power plants have the potential to deliver on three aspects of the UK’s energy policy:

  • Security of supply: The NuScale Power Module would deliver homegrown energy, reducing the UK’s dependence on imported fossil fuels.
  • Carbon emissions reduction: The technology would be a valuable addition to a low carbon energy mix, helping the UK to meet its legally-binding target of cutting carbon emissions by 32% by 2025.
  • Affordability: The estimated levelized cost of generating electricity from a VOYGR power plant is competitive with other forms of low carbon electricity generation being pursued in the UK.

Collaboration With Government

The recently released British government’s Energy Security Strategy outlined a plan to accelerate the use of nuclear energy as the single most effective way to achieve comprehensive energy independence in Great Britain. As described, Small Modular Reactors (SMR’s) will form an integral part of the nuclear project pipeline and we look forward to continued discussions and engagement with the UK government and with potential customers and developers to contribute to the success of the Energy Security Strategy.

For the past several years, NuScale Power has participated in many discussions on advancing the UK’s ability to build and deploy new sources of clean energy. NuScale’s groundbreaking SMR technology is well-positioned to play an indispensable role due to the following key factors.

Near-term ability to deploy

The NuScale plant is the only near-term deployable SMR technology, investing over $1.4 billion to develop our technology and prepare for deployment. We’ve completed 15 years of technology development resulting in the completion of critical testing programs, design validation, and are the first and only SMR design in the world to be approved in 2020 by the U.S. Nuclear Regulatory Commission (NRC). We have strong financial backing from the U.S. Department of Energy and are credible for deployment in Great Britain by 2029. This timeline is significantly earlier than any other supplier currently active in the industry.

Established strategic partnerships with world-class suppliers

Starting with a supplier day event back in 2016, NuScale has examined and conducted outreach with key UK suppliers like Sheffield Forgemasters, Peter Brotherhood, Doosan-Babcock and many other companies across the UK nuclear supply chain to develop strategic relationships that will enable the delivery of NuScale plants in the UK on time and on budget.

NuScale also has secured Fluor Corporation, an engineering, procurement and constructions partner, and has benefitted from their 60 years of experience in the UK nuclear market and in-depth understanding of the UK supply chain. Our strategic supplier relationships will evolve as UK customer project definition increases with the aim to maximize the local economic impact and job availability thereby making a significant contribution to the UK government’s Levelling Up Agenda.

Unmatched scalability and flexibility

To meet project economics and changing capacity needs, NuScale’s VOYGR power plants are scalable from 4-module (308 MWe) to 12-module (924 MWe) configurations that can maximize the generation of carbon-free energy at the UK’s available and approved sites. In addition, our SMR-powered generating facilities can provide process heat for multiple applications to develop a clean energy platform and thus support decarbonizing multiple sectors within the UK’s economy.

The competitive economics of NuScale’s VOYGR power plants and our ever-growing partnerships with companies across the British supply chain makes our technology a vital part of this strategy and the UK’s clean energy future. We applaud the UK’s leadership on this bold initiative and are committed to making our technology a vital part of its success.

Industrial Benefits

The prospect of a purpose-built manufacturing facility based in Britain would establish the UK as a leading player at the inception of a global small modular reactor market estimated to be worth up to £400 billion by 2035.

Development and deployment of the NuScale Power Module has the potential to generate significant opportunities for UK partner companies and wider economy.

NuScale Activities in the UK

NuScale Power is working with the UK government, various companies of strategic importance within the UK supply chain, universities and other institutions, to explore potential for the development, fabrication and deployment of the NuScale Power Module.


One example is Shearwater Energy, Ltd., a UK-based hybrid energy developer. In January 2021, Shearwater announced NuScale as the leading technology to provide carbon-free baseload and load-following energy to its planned wind-SMR hydrogen production project.

Under a Memorandum of Understanding, Shearwater and NuScale will generally explore opportunities for the combined generation of nuclear power based on NuScale’s leading SMR technology, offshore wind energy and hydrogen production at sites in the UK. NuScale will also specifically support Shearwater as it continues to develop the project, including conducting project-specific engineering, planning, and licensing activities for their SMR technology.

The wind-nuclear hybrid plant is expected to provide up to 3 GWe of offshore wind and SMR based carbon-free electricity at a significantly lower cost than conventional gigawatt size nuclear power plants. Surplus energy generation will focus on the production of hydrogen, supporting UK’s hydrogen goal of generating 5GW of low-carbon hydrogen production capacity by 2030 for industry, transport, power, and homes— aiming to develop the first town heated entirely by hydrogen by the end of the decade.
