Or toss the stuff just in front of a subduction zone.
For quite a while I've wondered whether it would be possible to put all our truly unrecyclable waste, nuclear and otherwise, into the mantle for very-long-term recycling. I'm glad someone else is thinking about geological solutions too.
It's been talked about for a while in places where you can find people who understand nuclear waste isn't magical, and that given where these zones are even if the waste dissolves and floats away it will have no impact on the ocean whatsoever. As you might imagine, there aren't many places where this gets talked about.
One fun number to tell people is that there are 4.5 billion tons of uranium in seawater [1]. Does it really matter if we toss a few tons of waste in to somewhere that is hundreds of miles from any significant life anyhow? (The ocean is not uniformly alive, the deeps are not very alive at all.) We can pack it up in ways that won't leak anyhow, like the well-known technique of embedding it in glass.
