A Germany-based world leader in nuclear steam turbine technology is set to bolster Rolls-Royce’ small reactor reactors (SMR). Siemens Energy has collaborated with Rolls-Royce SMR to supply steam turbines, generators, and other auxiliary systems for the British manufacturer’s planned Generation 3+ modular nuclear power plants.
Considered a promising technology for the future of nuclear energy, the SMRs can play a key role in the success of the energy transition as they are more compact, safer, and more cost-efficient than conventional nuclear power plants.
Currently, Rolls-Royce SMR is developing a “mini nuclear power plant” that can be operational much faster than traditionally built plants, thanks to its standardized, modular design.
Electrical output of up to 470 megawatts
The company has revealed that its pressurized water reactors are designed to achieve an electrical output of up to 470 megawatts, enough to supply approximately 1.1 million households with electricity.
“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,” said Karim Amin, a member of the Siemens Energy Executive Board.
“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. We are very pleased to be working with Rolls-Royce SMR on this exciting project.”
Steam turbines and generators
The company has revealed that it has been a supplier and service provider of components for the so-called “power island,” the non-nuclear part of the power plant. Siemens Energy’s solutions for nuclear power plants include steam turbines and generators with outputs ranging from 20 MW to 1,900 MW, as well as operational control technology and control systems.
With this new deal, Rolls-Royce SMR and Siemens Energy bring together their expertise to provide the complete turbine systems package covering design, manufacture, installation, and commissioning for a global fleet of ‘factory-built’ small modular reactor (SMR) power plants.
Rolls-Royce has maintained that forming an enduring partnership to deliver this key package of work significantly de-risks the programme and strengthens its ability to deliver SMR. This agreement will leverage Siemens Energy UK’s existing manufacturing base, and their global presence will ensure they are able to deliver in multiple countries.
Proven track record in nuclear steam turbines
“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,” said Rolls-Royce SMR chief executive.
“This partnership will unlock UK jobs and a range of manufacturing opportunities and further cements our position as Europe’s leading SMR technology. We are delighted that Siemens Energy will support our capability and enhance our ability to deliver a global fleet of Rolls-Royce SMRs.”
Rolls-Royce SMR maintains that it offers a radically different approach to delivering new nuclear power, with each plant providing enough low-carbon electricity to power a million homes for more than 60 years.
The company has been selected to deploy SMR units in the Czech Republic and down-selected for potential projects in the UK and Sweden. Success in these markets will create and sustain thousands of jobs, unlocking export potential and delivering a transformative effect on growth and the wider UK economy, according to a press release.
