Also just a thought re. your eg. on shipping.. I read a random blog a while back that suggested that a couple of large cargo ships go missing every week (sinking or piracy mostly). Not a thing I would like to see with nuclear reactors and material on board.

Just because some use cases are not practical for renewables now doesn’t mean they won’t be in the near future.
Everyone knows the externalities of nuclear power and it gets priced in to any discussion of new plants in 2019. The fear (about meltdowns) and concern (about waste) typically outsizes the actual risk substantially.
But most people don't seem to realize that coal far more produces aerosolized radioactive waste, other carcinogens, and as a result, cancer, per watt, than nuclear. Even if you assume every single nuclear plant melts down. Burnt coal is just absymal for public health, but it doesn't get the scary branding that nuclear power does.

Most of the people in my friend group actually live next to one. Zero issues, and it's an old communist party-built one.
But still, even if we're going to aggressively build out renewables there's still room for a lot more nuclear in the energy mix. There's use-cases for it where solar, wind etc. isn't a substitute, e.g. shipping[1].
