Long-range energy transmission was not practical back then, and hydrogen is a terrible storage medium.
As for power stations abroad, quite a few were built. But slow-neutron reactor usage cannot be scaled very much, probably less than order of magnitude. Practical uranium reserves just are not that huge. And fast-neutron reactors produce plutonium in large quantities.
But the main reason is vibes. The non-proliferation regime is maintained mostly not by a threat of force (Israel made nukes and nobody stopped them), but by a widely held opinion that they are only good for a MAD deterrence. Without radiophobia, nukes would be used as tactical weapons, and a lot more countries would want them.
