Clean, affordable energy for all

Our approach
Different, designed for delivery

Rolls-Royce SMR

The Rolls-Royce Small Modular Reactor (SMR) - the UK’s first domestic nuclear technology in more than 20 years - providing a British solution to a global energy crisis.

Drawing on more than half a century of Rolls-Royce engineering heritage, this technology has been developed by a team with an unrivalled track record in nuclear design, regulatory engagement, manufacturing and assembly.

Each Rolls-Royce SMR power station will produce enough stable, affordable and low carbon energy to power a million homes for at least 60 years – more than any other SMR.

Energy security and net zero are key priorities for countries across the world, there is a global upsurge in demand for nuclear power with a host of nations – including the US, Canada, France, Japan and Sweden – pledging to triple nuclear capacity by 2050.

Rolls-Royce SMR is up to eighteen months ahead of competitors in any European regulatory process and, with this first mover advantage, is in pole position to become a world leader in SMR technology and the UK’s premier green export technology.

470 Megawatts

Each Rolls-Royce SMR will generate 470 megawatts of low carbon energy, equivalent to more than 150 onshore wind turbines

1,000,000 Homes

Each Rolls-Royce SMR will create enough low carbon energy to power one million homes for 60 years

£54 Billion

A fleet of Rolls-Royce SMRs could result in a contribution of up to £54 billion to the UK economy between 2025 and 2105

1358 MWth

Each Rolls-Royce SMR will generate 1358MWth, equivalent to more than 45,000 domestic boilers

Our progress

  • Great British Energy - Nuclear

    Rolls-Royce SMR will build Britain’s next generation of nuclear power plants

    Rolls-Royce SMR has been named as the selected technology in the Great British Nuclear (GBE-N) small modular reactor (SMR) competition. The UK’s next generation of nuclear power stations will be designed and built by a British company, creating thousands of jobs, boosting the supply chain and creating growth for the economy.

    January

    Team of 15 engineers within Rolls-Royce come together with the challenge of developing an SMR that is low cost, deliverable, scalable and investable.

  • New nuclear is an essential part of the clean energy system we are building, but it’s also an essential part of the kind of economy we are trying to build.

    Ed Miliband, Secretary of State for Energy Security and Net Zero

  • SMRs can be a cornerstone of the long-term, secure and low-cost decarbonised energy system that can power the future economy.

    Tony Blair Institute for Global Change

  • Energy security, decarbonisation and electrification are fundamental to the growth and success of modern economies and the health of the planet, and have led to a significant and inevitable growth in the demand for new nuclear power.

    I am honoured to have the opportunity to contribute to Rolls-Royce SMR and the deployment of the UK's vital and deliverable solution to the global energy security challenge.

    Sir Stephen Lovegrove GCMG KCB, Rolls-Royce SMR Chair

  • Next generation technologies such as Small and Advanced Modular Reactors, new nuclear will both produce low carbon power and create jobs and growth across the UK.
