Since 1957, around 250 nuclear reactors have been shut down worldwide, representing a total capacity of 136,823 megawatts (MW). Data from Global Energy Monitor tracked these closures by country and territories through to 2025, revealing where the phaseout of nuclear energy has been most pronounced.
