The world's nuclear fleet in 1985
In 1985, 353 nuclear reactors were operating in 31 countries, 242.9 GWe net, with 132 under construction. 6 of those units are not included in the net capacity because no net figure has been published for them.
Compared with 1984, the operating fleet grew by 39 reactors. 34 reactors were connected to the grid that year, 32,226 MWe, mostly in United States (8), France (4) and Russia (3). 3 units were permanently shut down, 265 MWe. the Czech Republic and North Korea connected their first nuclear reactor in 1985. The countries with the most operating capacity were United States (79,399 MWe), France (33,810 MWe) and Japan (23,613 MWe).
