Big hole in the side of mountain in a desert, stick the waste in, full it with rubble and concrete, job done. If some primatives in a hundred thousand years stumble across it and dig it out, fuck em, who cares.
The pyramids have chambers that were unopened for over four thousand years, bone dry inside. Pick an area with very little rainfall, surround it with rock and the problem will stop existing on human timescales.
The hole would be 0.5m wide and >1000m deep, backfilled with bentonite clay and concrete. At the bottom, the path curves back upward, so waste is not stored at the bottom.
Even if geology doesn’t collapse the hole, it’s hard to imagine material climbing up through 1000m of clogged pipe.
Launching radioactive waste into space is a terrible idea, because rockets on occasion crash. Once that happens it becomes a nuclear disaster.
Instead we can safely store it in depleted mines.

There is no guarantee of anything.
But if you’re storing it hundreds of miles from the ocean, the risk is minimal.

That is not what I am suggesting.
Sealing a deep narrow borehole isn’t a difficult problem. The Earth has contained oil and gas underground for millions of years.
