Global nuclear reactor power output 2024, by reactor type
As of December 31, 2024, all operational pressurized water reactors (PWR) worldwide achieved a net electrical power output of Ìý²µ¾±²µ²¹·É²¹³Ù³Ù²õ. PWRs are the most common type of nuclear reactor used in nuclear power plants, with *** in operation at that time. Boiling water reactors (BWR) were the second most used reactor type, with a net electrical power of approximately **Ìý²µ¾±²µ²¹·É²¹³Ù³Ù²õ.
