Steam turbine solutions for nuclear power plants

Advanced steam turbines, generators, and control systems for both large scale nuclear plants and innovative Small Modular Reactors (SMRs).

As electricity demand continues to rise and power systems decarbonize, nuclear energy provides large scale, low carbon, dispatchable power that supports grid stability and energy security. Around the world, existing and new nuclear power plants play a critical role in delivering reliable electricity, day and night, in all seasons.

Siemens Energy supports this role by enabling nuclear power plants to perform safely, efficiently, and economically over decades of operation. Its nuclear power solutions focus on the steam side of the plant, where thermal energy is converted into electricity, and long term performance is determined.

Drawing on decades of nuclear experience, Siemens Energy is a trusted, technology-agnostic partner to nuclear operators worldwide. Its expertise lies in the conventional island, the systems that convert nuclear heat into usable electricity and determine how a nuclear plant performs over its lifetime.

The conventional island directly influences:

• Electrical efficiency and output
• Operational flexibility and grid interaction
• Long/term reliability, availability, and lifecycle cost

Siemens Energy focuses on the components that make up the conventional power island and supports reactor developers with power plant design, backed by the extensive nuclear heritage of Siemens KWU, Westinghouse, and Parsons. This rich legacy of more than 60 years enables providing tailor-made solutions that cater to the distinctive needs of nuclear power plants.

This expertise helps ensure efficient, reliable, and safe power generation, playing a key role in the global energy transition toward cleaner electricity. The collaboration with Rolls-Royce SMR highlights the commitment to the future of nuclear energy as a flexible and sustainable solution. 

Siemens Energy offers tailored steam turbine portfolio, which is designed to meet the unique demands of the nuclear sector.  Turbine island solutions offer steam turbine generator trains ranging from 2 MW to 1900 MW for nuclear power plants. These trains offer solutions from half speed applications with high power outputs, to turbines for small modular reactors (SMRs) recognized for their efficiency, reliability and availability. 

The comprehensive instrumentation and control systems are designed to monitor plant performance with precision and reliability. The expertise in extended water-steam cycle solutions helps promote an efficient and reliable plant operation. With a global supply chain and customized solutions, Siemens Energy can adeptly address local requirements, drawing upon substantial experience and flexibility.
