The world's nuclear fleet in 1989
In 1989, 426 nuclear reactors were operating in 31 countries, 325.4 GWe net, with 65 under construction. 6 of those units are not included in the net capacity because no net figure has been published for them.
Compared with 1988, the operating fleet grew by 12 reactors. 12 reactors were connected to the grid that year, 10,792 MWe, mostly in United States (3), Germany (2) and Ukraine (2). 8 units were permanently shut down, 3,241 MWe. Mexico connected its first nuclear reactor in 1989. The countries with the most operating capacity were United States (103,751 MWe), France (52,650 MWe) and Japan (28,183 MWe).
