While I agree that there is a lot of information being lost in the media grinder, and that the handling of Fukushima should be made into the poster child for clusterfuckitude, I would say that this is an example of (some) Japanese politicians taking some of the more rigid aspects of Japanese culture to task.
Also, contrary to what the GP is trying to say, this is not about making the technology appear safe and blaming human error. It even says this in the summary, "We cannot rule out the possibility that a small-scale LOCA (loss-of-coolant accident) occurred at the reactor No 1 in particular."
This reaction is the opposite of what has historically happened in Japan when this sort of issue arises. The ex-TEPCO execs and their government cronies are being lambasted in the press and on the net for being given cushy jobs and TEPCO is being nationalized. Hopefully, harsher measures will be applied (if the furor doesn't die down).
Hopefully, those responsible for the human errors will be made to pay for their mistakes, and those technological shortfalls will be shored up. If they can't be fixed, we'll have to find a new way of getting power.
