If I understand correctly, building the infrastructure is what makes is so expensive, but long term, the energy output more than makes up for those initial costs (especially if you use bitcoin miners to soak up the excess). I’ve also read that the waste disposal takes up a very small amount of space and there are better methods for disposable now, so compared to other sources the waste isn’t that bad. As for the heat off put, if we subbed nuclear for fossil it would still have a much much much smaller foot print than fossils because there’s no CO2 emissions from nuclear.
Correct me if any of that is wrong, I’m by no means an expert on this.
