What are Nuclear Steam Turbines?
Nuclear steam turbines are mechanical devices designed to convert high-pressure steam, generated in nuclear reactors, into mechanical energy that drives electricity generators. They are typically designed to handle unique requirements of nuclear power plants, such as:
- High thermal efficiency and long operating cycles
- Safety and reliability in harsh environments
- Compatibility with pressurized water reactors (PWRs), boiling water reactors (BWRs), and advanced reactors
- Low vibration and noise for long-term operational stability
These turbines are critical components in ensuring continuous, safe, and efficient energy generation.
Market Drivers
Rising Global Demand for Clean Energy
As countries seek to reduce carbon emissions, nuclear energy offers a reliable alternative to fossil fuels. This is driving investments in new nuclear power plants and upgrades to existing ones.
Modernization of Aging Nuclear Infrastructure
Many reactors built in the 1970s and 1980s require modernization. Replacing or upgrading steam turbines is central to extending plant life and improving efficiency.
