The world's nuclear fleet in 1980
In 1980, 237 nuclear reactors were operating in 24 countries, 129.9 GWe net, with 199 under construction. 6 of those units are not included in the net capacity because no net figure has been published for them.
Compared with 1979, the operating fleet grew by 12 reactors. 21 reactors were connected to the grid that year, 15,857 MWe, mostly in France (7), Finland (2) and Russia (2). 1 unit was permanently shut down, 39 MWe. The countries with the most operating capacity were United States (54,333 MWe), Japan (14,428 MWe) and France (12,360 MWe).
