I think storing nuclear waste was decided to be a bad idea a long time ago.
I'm not a nuclear scientist, but I was under the impression that if something is radioactive enough to be a hazard then it's radioactive enough to generate power.
Is that not the case?

Only under certain circumstances is it financially worth harnessing this power. I think of space probes and their RTGs. They use alpha emitters like Pu-238, to minimize the shielding requirements.
As for the rest of the stuff, dry casks are good enough. Reprocessing isn’t currently economical while uranium is so cheap, although the vitrification of the fission products can help immobilize the worst radiation emitters, but really the UO2 structure does a decent job of keeping things put.
A brand new Uranium fuel pellet is often safe to hold with gloved hands for a moment.
Spent fuel with complex decay isotopes must be kept under deep cooling pools with criticality control precautions. From a chemistry perspective, complex isotope products like Plutonium are more obscure to evolutionary biology, so it is often much more dangerous even in accidental trace exposures.
