Nuclear power was once the fasted growing energy producer in world history. Adoption happened faster then coal, faster then oil or pretty much anything else.
The world was on track to essentially replace fossil fuels with nuclear on a pace that was outside of human experience.
Humanity was quickly entering a new age. But then a small number of accidents lead to a political change, witch lead to regulatory changes that essentially killed nuclear power in most places.
Since the US regulatory system changed the amount of new plants built has essentially gone to 0, far below replacement. And many of the same effects were mirrored in most of the west with the US taking the lead.
The worst thing is that the new regulatory system not only killed the building of new plants, but essentially ended any hope of getting new reactor types into commercial use. No new reactor type have been licensed since then.
This seems rather strange because in the 60-70 new reactor-types were build at a rapid rate, constant innovation even with relatively small amounts of money. All of this was destroyed. Even in places where nuclear power is so clearly a huge win like NASA.
Nuclear fuel storage issues has entered into a political limbo where anti-nuclear lobby has essentially managed to deadlock the whole process and can since claim that nuclear storage issues can't be solved. At the same time the government collects money from nuclear power stations to handle the waste issue.
This is one of the saddest and most depressing stories in human history if you ask me. There is 0 scientific or technical reason why shouldn't have cheap nuclear power even in remote places, even in space.
