Advanced Nuclear Technologies

Building a better world with nuclear power

Since 1958 Rolls-Royce has been the sole custodian of the nuclear reactors that power UK submarines. Today, we have powered nearly 2.5 million hours of critical reactor operation.

That unrivalled expertise has been put to good use, developing innovative ways we can build a better world with nuclear.

Now, with a Nuclear portfolio that includes Advanced Modular Reactors and Small Modular Reactors (SMRs), we can power and connect, as well as protect. No other company in the world can provide that nuclear advantage to both defence and civil markets.

Novel nuclear – powering the future with nuclear

The global demand for clean, safe and reliable power is growing. Our Novel Nuclear programme is developing commercially viable solutions that provide long-term clean and safe power, bringing new energy and power dense technology to industry.

Rolls-Royce is the UK’s only nuclear reactor vendor with full lifecycle experience and end-to-end capability to deliver novel technologies based on proven, reliable power solutions. Our extensive expertise gives us unparalleled access to nuclear capability and a proven supply chain.

The multi-domain applicability of our nuclear technology ensures we can support commercial and defence use cases, creating world-leading power capability for multiple markets and operator needs.

The Rolls-Royce Advanced Modular Reactor (AMR)

The Rolls-Royce AMR is a compact solution to meet increasing demands for energy security. Providing clean, scalable and reliable power across civil, defence and industrial sectors.
