I have one question which somehow during this whole thing seems unasked by the news outlets and thus unanswered by the nuclear energy proponents and experts: If there weren't already(and it appears as if there weren't), why weren't there permanent backup fossil fuel powered generators built at these plants which after the loss of main power could have kicked in and continued to pump cooling water into the cores?
I mean, once again, IF these backup generators weren't built at these plants, that would seem a pretty dumb design to me!
And, IF there WERE these types of generators at these plants, then WHY didn't the process work?
