The world's nuclear fleet in 1969
In 1969, 83 nuclear reactors were operating in 15 countries, 11.3 GWe net, with 99 under construction. 9 of those units are not included in the net capacity because no net figure has been published for them.
Compared with 1968, the operating fleet grew by 11 reactors. 9 reactors were connected to the grid that year, 3,523 MWe, mostly in United States (3), India (2) and France (1). 1 unit was permanently shut down, 6 MWe. India connected its first nuclear reactor in 1969. The countries with the most operating capacity were United Kingdom (3,505 MWe), United States (3,190 MWe) and France (1,454 MWe).
