Smaller reactors bring nuclear power closer to fulfilling its promise

Small modular reactors (SMRs) are emerging as a promising alternative to conventional nuclear power plants, with companies like Kairos Power building demonstration units that use innovative fuels and coolants to reduce construction costs and timelines. The U.S. and European governments have committed hundreds of millions in funding to support SMR deployment, driven by growing demand for clean energy from data centers and other sources. However, critics argue that SMRs may not be more economical than larger reactors and could pose safety concerns due to their different fuel and cooling systems.
