> It’s the other way around. If the money poured into renewables had gone to nuclear there would be no climate crisis.
That's a very bold statement for which I have seen absolutely no proof. Solar and wind do not have the long term waste issues associated with nuclear and cost a small fraction of nuclear per installed Watt of power generation.
There is no significant difference in CO2 output of nuclear vs solar or wind so you'd have a climate crisis just the same. If you're looking to displace fossil fuel with nuclear you're going to have to look much further than just electricity, and solar and wind are just as good or even better at that as nuclear power is. Working fusion would be better than all of these options, but unfortunately we don't have it.
> There are 9 countries with nukes and 31 with nuclear power. The idea that nuclear power plants were build to acquire nukes seems unlikely.
It may seem unlikely to you but it is a well established fact. France, China the United States, Russia and the United Kingdom, some of the earliest nuclear powers all got into the nuclear plant game to make weapons grade material. The power generated was a by-product. Countries that got into the game later and that did not have access to nuclear technology were licensed 'safe' tech that could not be used for enrichment.
Iran and North Korea are only interested in nuclear power for weapons purposes, everything else is just a fig leaf.
