As of recent data, the United States leads the world in nuclear power generation by a significant margin. The second-largest producer of nuclear power is France.
Here’s a bit more detail:
- **United States:** The U.S. has the highest number of operational nuclear reactors and generates the most nuclear electricity overall. The country has around 93 reactors in operation, contributing a substantial portion of its electricity from nuclear energy.
- **France:** France is notable for its heavy reliance on nuclear energy. About 70% of France’s electricity is generated from nuclear power, which is the highest percentage of any country. France operates approximately 56 reactors, and its nuclear power plants are among the most efficient in the world.
The position of these countries in nuclear power generation can change over time as new plants are built or decommissioned, and as energy policies evolve.
