Nuclear is one of the cleanest sources of power, if not the cleanest period.

It requires least mining and materials over lifecycle vs any alternative per KWh. It requires least land. It's final waste volume is similar to renewables while both sectors do create toxic waste that must be stored forever (used fuel in case of nuclear and forever toxic chemicals like arsenic/lead in case of renewables)

Saying nuclear is dirty as hell means you either are ill informed or spreading lies on purpose

To give an example with Germany, probably being outpaced only by Austria in hate for nuclear power. Germans are concerned about small amounts of nuclear waste that will be stored in deep geo stable facilities (just like onkalo, soon fosmark, terradura and alikes) but germans are perfectly fine having the biggest near surface facility for storing forever toxic and dangerous chemicals on the planet, Herfa Neurode.

Not just that, many are unaware that having a repository longterm is still a must even if they don't have nuclear power at all, due to medical and research sectors
