I live ~30km from a nuclear plant, that was closed ~20 years ago due to that referendum.
I still remember it being built in the early 1970s (my best friend's dad was part of construction crew) and back then (cheap oil) they said there was no point in using the excess heat, and instead just heat up the ocean, rather than hot water pipes to the nearby towns, which today would have been a massive benefit (district heating networks exist in all towns).
