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.

Advanced Reactors

An advanced reactor is a category of next-generation nuclear reactor that encompasses a wide range of innovative designs and technologies aimed at improving safety, efficiency, and sustainability compared to traditional nuclear reactors. These reactors incorporate cutting-edge materials, advanced cooling systems, and novel fuel types to optimize energy production and minimize waste generation. Advanced reactors often employ passive safety systems, which rely on natural processes, such as convection and gravity, to maintain safe operating conditions without the need for active mechanical components. Some examples of advanced reactors include Small Modular Reactors (SMRs), Generation IV reactors, and molten salt reactors, among others. These reactors are being developed to address the growing demand for clean, reliable, and scalable energy sources while addressing the challenges and concerns associated with conventional nuclear power, such as waste management, proliferation risks, and public perception.
