Steam turbine components for Rolls-Royce SMR to be manufactured in the UK

Key steam turbine components for Rolls-Royce SMR’s first three small modular reactors at the Gwyndod project, on Anglesey in North Wales, will be manufactured at Siemens Energy’s Newcastle site – including high-pressure turbines and valve casings. This marks the first time such components will be produced for a small modular reactor anywhere in Europe.

The Newcastle facility is also planned to become the service hub for Siemens Energy’s key components for the Rolls-Royce SMR UK fleet. The historic CA Parsons Works site builds on the legacy of Sir Charles Parsons’ turbine works and has been a critical part of the UK’s energy infrastructure since 1889 – including building the steam turbine for Calder Hall in West Cumbria, the World’s first commercial nuclear power station which began generating in 1956.

Miatta Fahnbulleh, Secretary of State for Energy Security and Net Zero, said: "This is what our golden age of nuclear looks like in practice: skilled jobs in Newcastle, stronger British manufacturing and a more secure energy future.

"Producing these components here in the UK will help strengthen our energy security, reduce our exposure to volatile international gas markets, create new export opportunities for British industry, and reindustrialise the UK."

Secretary of State for Business, Innovation, Science and Trade, Jonathan Reynolds, said: "When the Prime Minister promised growth in every postcode, this is what he meant. This investment will support more than 550 good jobs for people in Newcastle and delivers on our pledge to reindustrialise Britain. Building small modular reactors here in the UK presents huge benefits for us, from more export opportunities to more jobs on the ground at home.

"Through our Modern Industrial Strategy, we are creating the conditions for businesses to invest in high-skilled jobs, strengthen supply chains and back the industries that can put more money in people’s pockets."

Simon Roddy, CEO of Great British Energy – Nuclear, said: “I’m delighted to welcome Siemens to the team delivering the UK’s first SMRs. Manufacturing these major components in Newcastle for our flagship project in North Wales demonstrates that every corner of the UK has a role to play in this programme. I’m particularly proud that we’re sustaining such a vital strategic capability, strengthening both our industrial base and the UK supply chain."

Rolls-Royce SMR selected Siemens Energy, a world leader in steam turbine technology, as its global turbine systems partner in February 2025, recognising the partnership’s potential to unlock UK jobs and significant manufacturing opportunities. The former Parsons site will, therefore, produce vital components for the Gwyndod project in the UK and for the growing SMR export market. Today’s announcement will support more than 550 jobs and create new opportunities in Newcastle.

Rolls-Royce SMR CEO, Chris Cholerton, said: "I’m proud of today’s announcement which clearly demonstrates how Rolls-Royce SMR is delivering its commitment to localisation, driving investment and reshoring work that would have taken place overseas.

"By working with Siemens Energy in Newcastle, we are building on a remarkable industrial legacy while creating and sustaining the skills and supply chain needed to deliver clean, secure and affordable energy for decades to come."

Darren Davidson, UK Vice President for Siemens Energy, said: "This is a significant moment for Siemens Energy and our Newcastle facility, for UK manufacturing and for Britain’s nuclear future. Building on a site with a world-class engineering legacy, we're preparing to manufacture the next generation of steam turbines for small modular reactors, supporting energy security, creating skilled jobs and helping power the UK’s future energy mix."
