Nuclear power is declining globally.
As of 2019, 417 nuclear reactors were operating in 31 countries. That includes 272 that have been operating for more than 30 years. The nuclear share of global power generation fell from about 17% in 1996 to about 10% in 2018.
As of 2020, 47 nuclear reactors are under construction, but many of them have been under construction for a long time or are expected to be put on hold, so the number is likely to decrease rapidly. To date, 186 reactors have been decommissioned and 93 have had construction put on hold.
