Sorry I’m late to this thread, but it seems like the ultimate disposal of nuclear waste would not be to put it underground or in orbit, but shoot it into the sun. Since the sun is a nuclear factory already, it would be sorta like coals to Newcastle, no?

Well, not really. The sun is powered by nuclear fusion of light elements, while our nuclear waste is the leftovers of fission of heavy elements. It’d be kinda like throwing a very tiny amount of sand onto a campfire; not likely to have any noticeable effect but not good for it, either.
