It’s also a bad idea because the “waste” might end up being useful/valuable to future generations. It’s only considered waste right now because we currently have no purpose for it.
As opposed to the raw uranium that we dug out of the ground? I don’t recall nature storing that inside radiation-proof barrels.
Also there’s the pesky fact of half-life. Ignorant anti-nuclear activists seem to think that nuclear waste is extremely dangerous and lasts for centuries. Nope. Nuclear material can either be imminently dangerous or have a centuries long half-life. It can’t be both.
