The world's nuclear fleet in 1967
In 1967, 67 nuclear reactors were operating in 12 countries, 6.6 GWe net, with 68 under construction. 9 of those units are not included in the net capacity because no net figure has been published for them.
Compared with 1966, the operating fleet grew by 1 reactor. 11 reactors were connected to the grid that year, 2,088 MWe, mostly in United States (4), France (2) and United Kingdom (2). 3 units were permanently shut down, 81 MWe. The countries with the most operating capacity were United Kingdom (3,196 MWe), France (994 MWe) and United States (936 MWe).
