I do kind of wonder about one thing, though... why are the engineers who designed that beast not being indicted? After all, nearly all of the vital pumps and generators were in the basements of both the Daiichi and Daini sites, with much of the critical equipment right next to the water, instead of uphill where they should have been (and at least not in basements... WTH, people?)
The Daini site lucked out big-time, with a monumental effort by the crews there to run enough cable from the few generators they still had working to the pumps which needed the juice - something like 2 miles of cable had to be scrounged and tied together.
BTW, props to the operators and supervisors onsite - for instance, the idea of scrounging car batteries and tying them together with inverters so that they could get the control panels back up was pretty genius. Same with having a special firefighting team from Tokyo come in to keep the storage pools full of water. At both sites they were stuck with having to come up with creative ways to avoid things from getting as bad as they could have.
I think that with a couple of design changes (both to the reactors and to the rest of the plant) they could have survived much better off than they were.
All that said, I don't think anyone could have predicted the size and scope of the tsunami that hit them. The TEPCO execs should still have to face a bit of music though (for instance, one site operator asking for 4,000 liters of water for a cooling pool and getting 4,000 bottles of drinking water instead? Damn, y'all...)
