Rolls-Royce Small Modular Reactors:
clean affordable energy for all

We are faced with an unprecedented demand for clean energy as global markets seek solutions on their journey to Net Zero. The demand is for energy that is always on and which generates no emissions. Nuclear energy is the most powerful source of always on clean energy, however, it must be deliverable, scalable and cost competitive for it to be widely embraced.  

At Rolls-Royce SMR Ltd we have designed a factory built nuclear power plant that will offer clean affordable energy for all.

About us

One clear vision

Rolls-Royce SMR has been established with a clear vision – to deliver clean, affordable energy for all

To achieve this goal, speed and certainty are critical. Because Rolls-Royce SMR is able to produce a repeatable factory-built power station, that relies on tried and tested nuclear technology, it can be constructed and made operational far more quickly than conventional bespoke nuclear design and build technology.

The Rolls-Royce SMR approach lowers cost, reduces uncertainty and risk for developers and crucially, allows countries around the world to address their urgent need for low carbon energy.

Our Vision

Proven technology,
innovative delivery

Rolls-Royce brings together global industry leaders in energy generation and engineering, who will harness the potential of this ground-breaking approach to sustainable nuclear power.

Rolls-Royce SMR uses established nuclear technology and knowhow, to offer a sustainable, low cost, repeatable and scalable product, that can be rolled out around the world.

What they are saying

We have 60 years of experience of producing small reactors for submarines, and we believe we can produce energy from SMRs at a cost at least comparable with renewables such as wind.

Warren East, CEO, Rolls-Royce

Nuclear power is central to tackling climate change, securing economic recovery and strengthening energy security. To do this it must be affordable, reliable and investable and the way we manufacture and assemble our power station brings down its cost to be comparable with offshore wind at around £50 per megawatt-hour.

Tom Samson, CEO, Rolls-Royce SMR

The UK SMR heralds a new approach to the cost of nuclear power by broadly rethinking the manufacturing and construction methods and by the extensive use of digital twinning whilst keeping the physics package exactly the same. This is a pressurised water reactor of a type we know and love.

Paul Stein, Rolls-Royce Chief Technology Officer

Small modular reactor technology is very much at the centre of what the Prime Minister outlined in the 10-point plan; in fact, the nuclear segment of that plan was the third item on the agenda and is extremely important. SMRs will certainly play a part in our nuclear future.

Rt Hon. Kwasi Kwarteng, Secretary of State for Business, Energy and Industrial Strategy

One of the benefits of the SMR approach, is it becomes quite a low-cost source of energy for other parts of the decarbonisation scene, such as hydrogen and synthetic fuel.

Paul Stein, Rolls-Royce Chief Technology Officer

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.

The Ten Point Plan for a Green Industrial Revolution, HM Government

SMRs represent a huge opportunity…they are flexible and one can operate them in lots of geographical areas. We will undertake a comprehensive assessment of the siting requirements for SMRs and advanced modular reactors so that we can develop this exciting technology.

Rt Hon. Kwasi Kwarteng, Secretary of State for Business, Energy and Industrial Strategy
