The two infographics above visualize the countries around the world that are currently developing small modular reactors (SMR) and the distribution of advanced reactors in development by reactor type. The first graph uses data from the IAEA’s SMR Technology Development report from 2022, while the second graph depicts data from the IAEA’s Advanced Reactors Information System (ARIS) database. Currently, the top five countries developing SMRs are the United States, Russia, China, Japan, and Canada. Additionally, aside from new generation pressurized water reactors, countries have made the most progress in developing sodium-cooled and lead-cooled fast reactors.
