In the past 10 years, more than 34 gigawatts (GW) of nuclear power capacity were added in China, bringing the country’s number of operating nuclear reactors to 55 with a total net capacity of 53.2 GW as of April 2024. An additional 23 reactors are under construction in China. The United States has the largest nuclear fleet, with 94 reactors, but it took nearly 40 years to add the same nuclear power capacity as China added in 10 years.
