The world's nuclear fleet in 1968
In 1968, 72 nuclear reactors were operating in 12 countries, 8.3 GWe net, with 98 under construction. 9 of those units are not included in the net capacity because no net figure has been published for them.
Compared with 1967, the operating fleet grew by 5 reactors. 8 reactors were connected to the grid that year, 1,000 MWe, mostly in Germany (2), Netherlands (1) and Panama (1). 3 units were permanently shut down, 46 MWe. the Netherlands, Panama, Spain and Switzerland connected their first nuclear reactor in 1968. The countries with the most operating capacity were United Kingdom (3,505 MWe), United States (1,910 MWe) and France (1,064 MWe).
