This is exactly what I'm saying - in case of a civilization collapse the safety of nuclear fuel will be the biggest problem. There is no magical way to cool the fuel without power - it produces a huge amount of heat and the only to avoid explosion is active water cooling.

yes but, by far most cooling systems doesn't need electricity after you lower the control rods and shut down the reactor, that was specific to fukushima.. and even if all 400 reactors melted down it would still be the least of our problems in such a scenario.
