I'm a fan of both, but fully accept that fission is now too late to be useful. We also have fusion right on the tipping point of viability. That could likely fill the use cases of fusion quite well, with far less issues.

FYI, nuclear produces 3 sorts of nuclear waste. High activity is nasty, but short lived. Put it in a pool for a few years and it decays away. Low grade is the stuff like lab waste and contaminated pipes. You don't really want it going in normal landfill, but it's not going to kill anyone with radiation (heavy metal toxicity is another matter). It's only the last type, medium activity that is problematic. It lasts a long time, while still putting out enough radiation to cause potential problems. Unfortunately, older "power" plants, were actually bomb factories. They were intended to make plutonium, and so produce a lot more of the medium activity waste than they could.
