Report released on Fukushima 3

[cloa]

A new very detailed report on the Fukushima nuclear power accident and events is available online from the Japan Nuclear Technology Institute.

But, seeing that we've had local blackouts combined with (lengthy!) area blackouts and major destruction at a couple of US nuclear sites (Browns Ferry, for example, had its transformer yard wiped out during a tornado), how will the lessons learned be applied?

More accurately, will the correct lessons learned be correctly applied, or will they be layered on more layers with only more layers of band-aids?

The source organisation is totally Japan nuclear industry funded organisation. It gives the lying sorry the disaster was unexpected line even though even internal TEPCO reports from last year predicted a higher tsunami than the their original limited analysis which seismologists warned as an insufficient consideration of history.

So, do you consider this report an attempt at a political whitewash?

The first few pages smell of whitewash, Foggy Bottom style.

I gave up around page 36 because I couldn't make sense of it.

Bottom Line [carefully not mentioned in report]: When the only viable source of water became seawater [via firetruck or other engine-powered pump], nobody would take responsibility/authority and use the seawater to cool the reactor cores and spent fuel pools.

The chlorides in the seawater would irreparably ruin the stainless steel system. The system was going to be irreparably ruined by a partial meltdown of the fuel elements anyway, without cooling. Then seawater would be required to stop the burning of the Zircalloy fuel rod tubes, that cought fire due to being uncovered.

The Japanese method of making major decisions is to hold meetings, discuss it at bars, and hold more meetings until a consensus is achieved. Time ran out before any consensus could be reached, and Fukushima got the worst of all the possible outcomes -- fire, hydrogen explosions, radiological release into the groundwater and seawater, and chloride contamination of their entire plant.
