Vitrification(solidification) and store safely underground somewhere with smaller risks of earthquakes. Ideally you would want the fuel to be reprocessed(like France did it) or to be used by a breeding reactor, this way the waste will be more dangerous only for about 300 years(it'll still be radioactive after but much less compared to waste that wasn't reprocessed or used by a breeding reactor. Why it's not done? It costs more money and most countries decided for now it's ok without these steps and breeding reactors kinda exist but are too few and not very well studied to build more

Thank you.

I mentioned risk models in another comment. In your opinion, is nuclear energy safe from irrational (state) actors? For clarification, note that even hydroelectric energy has a risk factor that it can not be protected against irrational state actors. Recent events in Ukraine a case in point. And that ‘system failure’ did have environmental impact.

The point I am trying to make regarding nuclear (fission) energy is that hazard and catastrophe are a continual concern, and will remain so long after we are gone. Unquestionably, nuclear fission is far less damaging than many other energy systems but on the hazard side of the equation it stands alone. We rely on various wishful thoughts, such as assured grasp of human competence, greed, rationality, to say nothing of failures in other systems (such as software guidance for missiles) and also acts of God such as geological events. And for how long? For the lifetime of the existence of the hazardous material and processes.

I'm not an expert, just an anon)) but with current new reactor designs and if at least vitrification is done, I don't think there's too much danger(I mean Fukushima lvl, Chernobyl imo is not possible at all), it's just storing some solid rock underground(or export that rock to countries like sweeden that do have storage space). Again, if planing longterm is too risky, reprocessing and storing for 300 yrs should be ok, there are enough geologically stable regions for such small timeframes. Reprocessing is also nice bc with it you get extra fuel called MOL that can be reused in classic reactors and that fuel can be reprocessed again.
