I mean, the way we got rid of our military reactor "waste" for decades was selling it to the French, who refined it for their reactors....

Real waste that's an issue is radioactively contaminated steal and the like, we can't use any of that juice, but we can keep refining fuel forever if we wanted to.

It's just a big heavy object, and we need big heavy payloads and an excuse to launch them. So let's take all that real waste and launch it at the sun for the fuck of it.
