[Cthulhu_]

An accident with spent fuel rods / nuclear waste will happen in our lifetimes, and probably in the US; the US does not have proper nuclear waste disposal because nobody wants to host it. Earlier they'd just dump it in the ocean, but now, it's stashed in the nuclear plants' spent fuel rod basins, waiting (for decades now) for the country to build a proper disposal facility. IIRC the last one was a huge project inside a mountain somewhere.
