I have not followed this thread from the beginning but want to make a comment.

my background includes MS in solid state and nuclear physics so i do understand the process.

this accident was entirely preventable and the engineering staff had tried to prevent it from happening over the previous 10 years.

they knew that a tsunami would over-top to the sea wall and flood the generators in the likely event of another earthquake.

the engineering staff had recommended to management that a new generator be installed higher up the cliff above the facility.

they had also requested that the power switching station which connected the generators to the coolant pumps be raised above the flood level also.

management finally approved and installed another generator higher up on the cliff.

management refused for another 2-3 years to move the power switching substation because they said they were afraid to provoke the antinuclear protesters who would block them.

so when the tsunami over-topped the sea wall and flooded the generators, the power switching substation was also flooded and rendered useless.

that was why the generator which had been installed to save the plant in this very event was not not able to provide power for the coolant pumps.

also, the plant manager decided, too late, to flood the reactors with sea water in spite of efforts by the president of TEPCO to prevent him from flooding it with sea water.

if he had not done this the meltdown would have been catastrophic and could have involved a criticality event as at Chernobyl.

there was never evidence to support management's contention that they could not get a move of the power switching station approved.

it appears they just refused to accept the engineering staff's recommendation. that is the general nature of management structure in japan imo.
