Rolls-Royce SMR

Rolls-Royce SMR

Our origins are deeply embedded in Rolls-Royce and their world-class nuclear and manufacturing heritage.  Our Intellectual Property and resource expertise is built on the foundations of a company that has over seven decades of experience in designing and delivering nuclear solutions.

Our nuclear experience is complemented by our unique aerospace know-how of manufacturing, supply chain management and logistics. Together, that heritage and experience is at the core of our SMR program.

Designed and built in the UK

During our early stages of development we established a Consortium of industry partners to support the development of a fully integrated nuclear power plant solutions. Those Consortium partners will now work with us as supply chain partners, committed to continuing to support our program with their power plant, engineering, civils design, fuel, advanced manufacturing, project delivery and nuclear technology expertise.

Creation of a new company

The next phase of our development has begun with the creation of a new company, Rolls-Royce SMR Ltd, created specifically to deliver our innovative SMR solution and establish a new relationship with our shareholders who have invested equity alongside Rolls-Royce, to support the growth and development of our new business.


Rolls-Royce SMR uses established nuclear technology and know-how to offer a low cost, deliverable, global & scalable and investable solution, that can be rolled out around the world.

What they are saying

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

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.

Rolls-Royce is a great British company, which is why we previously made up to £210 million available from the advanced nuclear fund to Rolls-Royce SMR Ltd to support the development of its small modular reactor design.

Parliamentary Under Secretary of State (Minister for Nuclear and Networks), Andrew Bowie MP

SMRs are one of the most advanced nuclear power technologies in the world. Rather than having to be built on site, they're smaller and can be made in factories, transforming how power stations are built by making construction faster and less expensive. This tech could result in billions of pounds of public and private sector investment.
