Kenichi Ohmae, Tepco advisory committee member and designer of Fukushima Daiichi reactor core: After the accident I pointed out the possibility that the bottom of the PCV was damaged in addition to the RPV and have spent a year analyzing the accident.

At 3:00 in

Ohmae: I am not yet sure if it is due to a lack of Tepco’s analytical abilities or their tendency to cover up inconvenient facts, but it is clear that Tepco and I have quite different views on the accident.

Given my past experience in designing the reactor core I believe that it is my duty to analyze the accident in detail…

More from Ohmae regarding the damaged containment vessels:

    "Had the Commission made assumptions about the possible loss of the external electrical supply and ordered the plant to be equipped on site with other external power generation, be that solar, wind, gas turbine or even small LNG power stations to back up the six gigantic reactors, this disaster could have been averted."

    This is still a nuke guy. A better idea would be to have installed wind, solar, and tidal power at Fuku, and forget about putting in the 6 nuke plants.

      didn't Arnie Gundersen tell us many times that in the event of power failure the heat from the reactor itself would drive the pumps?

      wasn't the failure in not getting the water from the damaged inlets?

      more to this than we are told.

      • chrisk9

        Great point Pierre. There is a system (High Pressure Steam Injection= HPSI?) that should work with the remaining steam in the system to pump water for hours. This is a very important piece of the redundant safety systems, and the system failed in units 1-3. I remember it was mentioned in some of the transcripts, but I forget the reason it was not operable in any of the units. Probably damaged in the earthquake. Huge fail, and should impact every BWR's in the world.

        • pierre

          unlike some esteemed colleagues here, I am too lazy to go back to look it up, but I do recall arnie talking about the 80's ? modifications to the torus ? that required some human dude to go down to manually open up some gates. that also excludes electronic failure. it would take minutes ( 15?) for this to occur.
          perhaps it was too late by then.
          that sort of manual powering – from the heat already there – and a manual gate would exclude my pet theories of stuxnet , UNLESS, the operators thought that everything was ok because the instruments lied and until it wasn't safe to go down there (TEPCO wanted to evacuate the site recall). makes sense to me, but I don't expect to read about it this side of the revolution, and when has there ever been a genuine glasnost.

            This would work fine if you don't have to take into consideration that there were huge amounts of radiation from the leaking pipes and torus by then, preventing you from getting close enough to close the valves. No just need several auxiliary backup electrical and hydraulic systems. water or air hydraulic so they can't start on fire.

  • Urban27

    These guys are soo polite and they are offering their aid, and their alternative view. Probably this means they are critical to the way TEPCO is behaving.
    I wonder what the answer was?

    Probably something as polite from Tepco saying: "Thank you for showing interest…"

    • Fury Fury

      even WAAAY back Japan has been a very polite people, on the surface. But watch they'll stab you in the back, very politely ofcourse!! just depends on how ticked of they get or what's in it for them. Remember WWII. They even die politely! Exscuse me sir, let me get my guts out of your way.! But they do get a job done when under stress and usully faster than anyone else.

  • This so-called "independent" commission is clearly just going to be another whitewash that TEPCO wants to slap on top of the problem.

    Here's what MY independent study shows: TEPCO SUCKS, they have no plan and are putting everyone on the planet at risk every day.

    • Sickputer

      +311. Whitewash… Somehow I get that feeling also.

      Smear job might be another term. Somebody is getting set up for the blame (the vaunted "physical causes" versus the natural causes (like the biggest earthquake in 1200 years).

    • Fury Fury

      so what's your solution if you have any. saying everything sucks does'nt solve any problems.

  • Flapdoodle Flapdoodle

    To me, this is an admission that alternative energy is more reliable.

  • AGreenRoad AGreenRoad

    There is green wash and then there is FUKU wash…

    Nothing that happened before holds a candle to what happened at FUKU.

    FUKU is orders of magnitude worse than all that came before it… but it will not be the worst if we do not learn from this and stop playing with nuclear power.

    The video may be looked at as a desperate sales job.. trying to sell a dead, stinking dinosaur to people who have been stomped on and eaten by that dinosaur.

  • weeman

    They seem to be at the end of their rope in dealing with tepco, even they can not get answers to their questions and their proposals seem to be put on back burners, they can only act on the information they are supplied and even they Are kept in dark.

  • TheBigPicture TheBigPicture

    Tepco is like "Fred's Filling Station" and the whole industry wants to blame a corner gas station for the Exxon Valdez oil spill. But nuclear disasters are a million times worse. Millions. So now you and your love one's will die of cancer. You are literally hanging around, hoping that things are "ok", while you are waiting for your cancer. It's what it is.

    Wish is was otherwise.

  • RichardPerry

    Kenichi Ohmae, why did the plant not handle a 8 rated earthquake or a 30 foot tsunami as that would be about the strength that far from the centre of the quake.
