it’s not the nuclear waste itself, it’s that a nuclear power plant requires our society to stay in its modern, technologically advanced state, with competent scientists and political leaders at the wheel, forever.
remember when trump fired all the nuclear scientists? yeah.
This argument against nuclear is "Hypothetically in some distant future where society for some reason can't understand why this resource shouldn't be opened, it COULD cause catastrophe" while coal & fossil fuels actively destroys the world with a 100% climate catastrophe rate
