Global Leaders in Nuclear Energy Generation

Several nations lead in nuclear power, both in terms of operational reactors and the percentage of electricity generated from this low-carbon source.

The top 3

Countries with Most Operational Nuclear Reactors: The United States has the most operational nuclear reactors globally with 94 units, followed by France with 57 and China also with 57 reactors.
Nations with Highest Nuclear Electricity Share: France generates the largest share of its electricity from nuclear power, at about 65%, with Ukraine, Slovakia, and Hungary also relying on nuclear for around half of their electricity.
Emerging Nuclear Reactor Technologies: Advanced Generation IV nuclear reactors, such as Sodium-Cooled Fast Reactors, Very High Temperature Reactors, and Molten Salt Reactors, are being developed by an international cooperation of 14 countries, aiming for deployment as early as 2030, offering improved safety, efficiency, and waste management.
