Siemens Energy has been chosen by Rolls-Royce SMR as its exclusive partner for turbine systems in the development of small modular reactors (SMR).
This collaboration will see Siemens Energy providing steam turbines, generators, and auxiliary systems for Rolls-Royce’s Generation 3+ modular nuclear power plants. The finalisation of the contract is anticipated by the end of this year.
The partnership aims to utilise Siemens Energy UK’s manufacturing capabilities and global reach to support deployment in various countries. It is also expected to reduce risks and enhance the delivery capacity of the SMR programme.
According to Siemens Energy, SMRs are gaining attention as a future-oriented technology in nuclear energy, offering advantages such as compact design, enhanced safety, and cost efficiency compared to traditional nuclear power plants.
Rolls-Royce SMR is developing a standardised modular design that can expedite operational readiness. These pressurised water reactors are designed to generate up to 470MW of electricity, potentially powering approximately 1.1 million households.
Siemens Energy indicated that its longstanding experience in supplying components for the non-nuclear part of power plants positions it well for this venture. The company provides solutions like steam turbines and generators with outputs ranging from 20MW to 1.9GW, along with operational control technologies.
Siemens Energy executive board member Karim Amin said: “We are currently experiencing a global renaissance of nuclear energy. Numerous countries are turning to nuclear technology to produce low-emission electricity, and small modular reactors will play a key role in this.
“Siemens Energy brings decades of experience in conventional equipment, while Rolls-Royce has the necessary implementation expertise. This perfect symbiosis enables us to jointly shape the future of energy supply.”
Rolls-Royce SMR’s approach aims to deliver low-carbon electricity efficiently, with each plant capable of powering a million homes for over six decades.
A single power station will occupy an area equivalent to two football pitches and support both grid-connected and off-grid clean energy solutions. This includes aiding industrial decarbonisation and producing sustainable fuels like green hydrogen and sustainable aviation fuels (SAF).
Rolls-Royce SMR has been chosen for SMR deployment in the Czech Republic and is under consideration for projects in the UK and Sweden. These initiatives are expected to create jobs, enhance export opportunities, and contribute significantly to economic growth in the UK.
Rolls-Royce SMR chief executive Chris Cholerton said: “The turbine systems are a vital part of the Rolls-Royce SMR power plant, and we are delighted to be working with Siemens Energy, a global leader in energy systems who have significant experience and a proven track record in nuclear steam turbines.
“This partnership will unlock UK jobs and a range of manufacturing opportunities and further cements our position as Europe’s leading SMR technology.”
