Reactor and electricity data: International Atomic Energy Agency Power Reactor Information System (PRIS); US Energy Information Administration; company data; World Nuclear Association estimates
World Nuclear Association, The Nuclear Fuel Report (published September 2023, Reference Scenario) – for uranium requirements
Notes:
68,920 tU = 81,273 tU3O8
Operable = Connected to the grid.
Under Construction = First concrete for reactor poured, keel laying for floating plants.
Planned = Approvals, funding or commitment in place, mostly expected to be in operation within the next 15 years.
Proposed = Specific programme or site proposals; timing very uncertain.
* World figures include Taiwan, which generated a total of 11.7 TWh from nuclear in 2024 (accounting for 4.6% of Taiwan's total electricity generation). The island's last reactor was shut down in May 2025.
† Under Construction figures include a number of units where construction is currently suspended: Angra 3 (Brazil); Ohma 1 and Shimane 3 (Japan); Khmelnitski 3&4 (Ukraine).
‡ Ukraine 2024 electricity generation estimated.
New plants coming online are largely balanced by old plants being retired. Over the past 20 years (2005-2024), 106 reactors were retired as 102 started operation. However, the reactors grid connected during this period were larger, on average, than those shutdown, so capacity increased by about 21 GW.
TWh = terawatt hour (billion kilowatt hours); kWh = kilowatt hour; MWe = megawatt (electrical as distinct from thermal).
