Does anyone here know to what extent the nuclear power industry or the feds have planned for the possibility of a prolonged widespread grid-down scenario? My understanding is that all nuke plants have emergency generators with fuel on site to last anywhere from a few days to a few weeks. To what extent the containment vessel might protect us from a core meltdown I don’t know but for sure the spent fuel pools are not so well secured. They will meltdown catastrophically very quickly if we can’t keep cold water circulating. Just look at what happened in Japan. An EMP, terrorism, cyberwar, or even major pandemic can bring the grid down.
It seems that all disaster planning scenarios assume regional events in which help can come from elsewhere. They don’t ever talk about what happens if the grid goes down nationwide. I’m guessing that’s because they don’t have a plant to keep the nuke plants from melting down.
Am I misunderstanding something?
