Yokogawa will supply controls for Rolls-Royce’s small modular reactors
3 February 2026 
Rolls-Royce SMR has formed a strategic relationship with Yokogawa Electric to deliver the data processing and control systems (DPCS) for the Rolls’ planned fleet of small modular reactors (SMRs). Under the agreement, Yokogawa will develop and deliver the main control system, including design engineering, validation and qualification, product hardware, building and testing the system, installation and commissioning.
The project will be delivered and supported from Yokogawa’s UK office and design facility in Runcorn, Cheshire, working with teams in the Czech Republic and the Netherlands. Yokogawa has committed to making “considerable” investments, helping to secure jobs and strengthening the UK’s nuclear supply chain.
“This agreement to provide the power station’s ‘central nervous system’ marks another significant milestone as we accelerate towards delivering the first in a global fleet of Rolls-Royce SMRs,” says Rolls-Royce SMR’s operations and supply chain director, Ruth Todd. “We’re proud that a substantial portion of this work will be carried out in the UK and the Czech Republic – creating jobs, developing skills, and driving growth in the regions where our first plants will be built.”
Koji Nakaoka, executive vice-president and executive officer in Yokogawa’s Energy & Sustainability business, adds that his company “will deliver reliable, high-performance control systems to enable the safe, efficient, and sustainable deployment of nuclear power worldwide.”
The Rolls-Royce SMR is the UK’s first domestic nuclear technology in more than 20 years. Each small modular reactor will produce enough “affordable” emission-free energy to power a million homes for at least 60 years.
Rolls-Royce SMR has been selected as the preferred bidder by Great British Energy – Nuclear to build the UK’s first SMRs at Wylfa on Anglesey. The site will be capable of delivering up to 1.5GW of low-carbon energy, supporting the UK’s net-zero goals and creating 8,000 long-term jobs in the UK.
In 2024, the Czech utility ČEZ formed a partnership with Rolls-Royce SMR and is planning to build up to 3GW of new nuclear power in the Czech Republic. It is also one of two companies to reach the final stage of a process to identify a nuclear technology partner for Sweden.
