Why China is betting on big nuclear reactors

China is rapidly expanding its nuclear power capacity with large gigawatt-scale pressurized-water reactors, nearly doubling its fleet since 2016. The U.S. and France, traditional nuclear leaders, have struggled to add new reactors, with the U.S. only completing two units at Plant Vogtle. Smaller reactors, including microreactors like Antares' sodium-cooled Mark-0, are gaining attention in the U.S. as potential solutions for faster deployment and lower costs.
