Advanced reactors help pave the way for nuclear power to meet climate goals

Advanced reactors are helping to make nuclear power a more accessible, sustainable and affordable low carbon energy option. With enhanced safety features and designs optimized for cost-effectiveness, these reactors are expected to open the door to better economics, streamlined licensing processes and greater public acceptance, ultimately helping countries to consider nuclear power towards achieving their climate goals. Advanced reactors and associated fuel and fuel cycles represent the cutting edge of nuclear power technology. Their designs build on over six decades of research, development and lessons learned in nuclear power. The IAEA works together with countries to identify and address challenges associated with the development of advanced reactors, such as technological innovation and safety design criteria. This support includes collaborative research projects and activities such as workshops with international experts, as well as cooperation with the Generation IV International Forum (GIF), an international cooperative endeavour that now includes 13 countries. Since its establishment in 2000, GIF has been carrying out research and development activities to support next generation nuclear energy systems. Some distinguishing features of advanced reactors include enhanced thermal efficiency, waste minimization, optimized use of natural resources and the ability to address both electricity production and non-electric applications of nuclear power, such as hydrogen production. These features expand operating potential and vastly improve nuclear power plant economics.
