Who we are

Rolls-Royce SMR’s small modular reactor (SMR) programme is the first of its kind in the UK.

A Rolls-Royce SMR power station will have the capacity to generate 470mw of low-carbon energy, equivalent to more than 150 onshore wind turbines. It will provide consistent baseload generation for at least 60 years, helping achieve the Government’s target of 24GW of nuclear energy by 2050.

In addition to stable base load power, Rolls-Royce SMRs will be able to provide energy for the manufacture of green hydrogen and synthetic fuels, to support the path to Net Zero and the decarbonisation of transport.

Out technology is based upon well-established Pressurised Water Reactor (PWR) technology, in use all over the world, but Rolls-Royce SMR’s unique approach will see the reactor components built in factory conditions and assembled on site.

Our factory-built model is entirely scalable, as demand increases, we invest in further factories using the same design and management systems used for all our SMRs.


When fully operational the Rolls-Royce SMR programme is forecast to create 40,000 regional UK jobs by 2050 and generate £52bn in economic benefit.  

Having begun the design assessment process with the UK regulators, the organisation is at a point where it needs to significantly increase its workforce, offering candidates the opportunity to work with cutting edge technology within a world-class team.
