A Small Modular Reactor (SMR) is a type of advanced nuclear reactor characterized by its compact size, enhanced safety features, and modularity. SMRs are designed to generate electricity or heat by harnessing the power of nuclear fission, while offering a smaller footprint and lower costs compared to traditional large-scale nuclear reactors. With their modular design, SMRs can be built off-site in factories, allowing for standardized production, faster deployment, and scalability as multiple units can be added or removed depending on energy demand. These reactors are equipped with advanced passive safety systems, which rely on natural processes like convection and gravity, rather than active mechanical components, to ensure the reactor’s safe operation. SMRs are considered a promising option for increasing the share of low-carbon energy in the global energy mix, particularly in regions with limited grid infrastructure or where large-scale reactors are not feasible.
