Siemens Energy and Rolls-Royce SMR have entered into a partnership agreement that is expected to lead to the exclusive supply of conventional technology for future small modular reactors (SMRs). Under this agreement, Siemens Energy is to be the sole supplier of steam turbines, generators, and other auxiliary systems for the British manufacturer’s planned Generation III+ modular nuclear power plants. The final contract, detailing all specifics, is expected to be completed by the end of 2025.
SMRs are considered a promising technology for the future of nuclear energy and a key factor in the success of the energy transition. They are more compact, safer, and more cost-efficient than conventional nuclear power plants. Rolls-Royce SMR is currently developing a “mini nuclear power plant” that can be operational much faster than traditionally built plants, thanks to its standardized, modular design. Rolls-Royce SMR’s pressurized water reactors are designed to achieve an electrical output of up to 470 MW, enough to supply approximately 1.1 million households with electricity.
For decades, Siemens Energy has been a supplier and service provider of components for the so-called “power island,” the non-nuclear part of the power plant. The company’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.
Karim Amin, a member of the Siemens Energy Executive Board, commented: “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. We are very pleased to be working with Rolls-Royce SMR on this exciting project.”
