Abstract

 Small Modular Reactors (SMRs) represent a transformative development in nuclear power technology, offering potential solutions — including electricity generation, district heating, water desalination, hydrogen production, and process heat — to meet the growing demand for clean and sustainable energy. Their smaller size, modular design, improved safety features, flexibility, scalability, and reduced capital costs distinguish them from conventional large-scale nuclear power plants. This review examines the historical background, technological developments, design principles, safety considerations, economic feasibility, and regulatory issues surrounding SMR technology, with attention to its potential to revolutionize the energy sector and contribute to a sustainable, low-carbon future. SMRs are generally defined as reactors with an electrical output of up to 300 MW(e) per unit, compared with 1,000 MW or more for a typical conventional reactor, and are designed with passive and inherent safety features that reduce the likelihood of accidents relative to traditional reactors.
