Global nuclear power operating capacity reached 392.1GW(e) at the end of 2019, according to the International Atomic Energy Agency’s (IAEA). Data collected by collected by the Power Reactor Information System (PRIS) show this consisted of 443 operational nuclear power reactors in 30 countries.
Since 2011, the overall nuclear power capacity has shown a gradual growth trend, with 23.2 GW(e) of new capacity in newly connected units or upgrades to existing reactors.
However, global capacity fell by around 4.5 GW(e) compared in 2019 compared to 2018, because of Japan’s decision to permanently shut down five reactors that have not produced power since 2011.
At the end of last year, 54 reactors with a capacity of more than 57.4 GW(e) were under construction in 19 countries. This includes four countries building their first reactor.
