"The biggest issue with nuclear is that all current practical economics models emphasise short-term outcomes"
No, the biggest issue is that the public hate them, since they all grew up reading comic books about multi-tentacled super-mutants and nuclear meltdowns that turn the planet into Mad Max World. The reality of nuclear power is basically irrelevant as long as the general population has effectively zero understanding of them, and zero interest in learning about them.
