Fusion has a silly-high neutron flux, unfortunately. Aneutronic fusion... good luck with that.
Fission - decent fission cycles, not the silly strawman that people like to bring up ("once-through" and the like) - actually has less byproducts than fusion. It's the 'chop one twig off of a tree and burn it then call the rest waste'-style approaches that are terrible.
Why not just put all the waste into rockets and fire them into the sun? Will just get evaporated
Or just drop it into the Mariana Trench, very low energy expenditure, very solid disposal. But it might kill some super rare creature.
Waste of energy and resources :/
Because rockets have a rather ... troubling safety record?
Also, it takes a lot of thrust to head towards the sun.
Well, fusion has no byproducts to dispose of, and we're officially speaking "really close" to having compact fusion reactors already.
