Can the same not be said of nuclear to a degree? My knowledge may be outdated but afaik proper, long-term nuclear waste storage is still an open question.

Nuclear waste persists and remains dangerous for a long time and it's easy to forget and just burden future generations with it.

I think most jurisdictions have settled on or are settling on long-term underground storage. Usually in areas that are geologically stable, possibly between clay layers in case of leakage.
