Sources:
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 2021, reference scenario forecast) – for uranium requirements
Notes:
62,496 tU = 73,698 t U3O8
Operable = Connected to the grid.
Under Construction = First concrete for reactor poured.
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 26.8 TWh from nuclear in 2021 (accounting for 10.8% of Taiwan's total electricity generation). As of March 2023 the island has two operable reactors with a combined net capacity of 1874 MWe.
** International Energy Agency data for year 2019 (latest available).
† Under Construction figures include a number of units where construction is currently suspended: Ohma 1 and Shimane 3 (Japan); Khmelnitski 3&4 (Ukraine).
‡ Baltic 1, a VVER-1200 unit, commenced construction in Kaliningrad in Russia in February 2012. Construction was suspended in July 2013, and in 2017 the RPV made for Baltic 1 was sent to be used in Ostrovets 2 in Belarus. The unit is shown as under construction in PRIS, but was removed from the WNA's database in November 2020.
New plants coming online are largely balanced by old plants being retired. Over the past 20 years (2002-2021), 108 reactors were retired as 97 started operation. However, the reactors grid connected during this period were larger, on average, than those shutdown, so capacity increased by about 10 GW. The reference scenario in the 2021 edition of The Nuclear Fuel Report (Table 2.5) has 123 reactors closing by 2040, and 308 new ones coming online (figures include 28 Japanese reactors online by 2040).
TWh = terawatt hour (billion kilowatt hours); kWh = kilowatt hour; MWe = megawatt (electrical as distinct from thermal).
