It then extrapolates to a prediction that the whole world could be on 100 % nuclear power within 25 - 34 years. This must assume that the rest of the world has similar government support and cooperation, similar stable, honest leadership, sound economies, industrial capabilities, education systems, etc. and that the construction companies and nuclear fuel demands for France and Sweden can be quickly increased to those of the whole world. It assumes that the world will use the same nuclear technology as the Swedish and French programs of the 1970s to 90s. In reality, it may take several hundred years to replace 50% of fossil fuels with advanced nuclear technologies that still need development and testing.
