What are Small Modular Reactors (SMRs)?
Small Modular Reactors (SMRs) are advanced nuclear reactors. They have a power capacity up to 300 MW(e) per unit, much smaller than conventional nuclear plants. They are used for factory fabrication, easier transport, and flexible deployment. SMRs are suitable for remote areas, industrial sites, and grid support applications.
How Modular Nuclear Reactors Work
Modular nuclear reactors operate using the same basic principle as traditional nuclear plants. Nuclear fission generates heat. It produces steam to drive turbines and generate electricity. Their modular design enables major components to be pre-built in factories and assembled on-site. It reduces construction time, costs, and operational complexity.
Key Benefits of Small Modular Reactors
- Faster construction and deployment due to factory-built modules
- Improved safety features with passive cooling and simplified designs
- Flexible scalability by adding multiple modules based on demand
- Reliable low-carbon electricity generation for clean energy transition
- Suitable for remote locations, industrial zones, and off-grid applications
- Potential integration with hydrogen production and district heating
