You’re referencing an undergraduate memo. I’m sure you could find something more authoritative if you want to try and convince people nuclear waste is an insoluble problem.

Nuclear waste is a political problem not a technical one. It’s either still hot and could be used for fuel or not and relatively safe. The hot stuff can be burned in reactors; we don’t because that requires plutonium cycle with the obvious weapons uses. Cold waste can be allowed to decay for a few decades, vitrified by mixing with molten glass so it’s chemically inert and stored in a geologically inactive area, anywhere far from continental plate boundaries deep in the ground[1]. It could also be dumped in deep marine trenches at subduction boundaries where it would eventually be returned to the earth’s core. If you want to get it off Earth altogether I’m sure we could get it to the moon if we really wanted.
