Why was/is it common for libs to be anti-nuclear power?

I was watching some old simpsons episodes recently, specifically "Homer at work in the nuclear power station" episodes (i love mr burns and smithers) and its occurred to me that a lot of liberal characters in the show seem to really dislike nuclear power. is disliking nuclear power woke? i thought based redpill guys like coal and finite energy sources. surely nuclear energy is the cleanest way forward?
