Four days before March 11 quake, Japan gov’t told that 30+ ft tsunami could hit Fukushima plant

Japan utility knew of tsunami threat: government, AP, August 24, 2011:

Japan’s nuclear regulator says the operator of a damaged nuclear plant knew it might be hit by a far bigger tsunami than it was designed to withstand.

The Nuclear and Industrial Safety Agency says the operator informed it just four days before Japan’s massive March 11 earthquake and tsunami that waves exceeding 10 meters (33 feet) could hit the Fukushima Dai-ichi nuclear plant. […]

The tsunami that hit the plant had 15+ meter waves

    It was the quake that broke the pipes and lost the coolant!

    Or am I missing something here?

    There is probably no way of knowing for sure if it was the quake, tsunami, or combination that did it. The stories have been all over the place. I dont think they even know for sure, its definately hard to know what u can believe or not when coming from the japanese goverment.I just hope they get what is coming to them, even the american and canadian goverments should be held responsible for not warning thier own people of the radiation levels and dangers. Would love to hear of some of these people being sent to prison where they belong.

    Remember that the workers may have manually shutdown the cooling system for Reactor #1 BEFORE the tsunami hit. Could it have survived both the quake and tsunami if this was not done? Human error may be the important factor with this disaster.

    ●Nuclear plant cooling system manually shut down
    The operator of the Fukushima Daiichi nuclear power plant says workers may have manually shut down the No.1 reactor’s emergency cooling system in order to prevent damage to the reactor. It says pressure inside the reactor had dropped sharply after the earthquake struck the plant on March 11th. Tokyo Electric Power Company on Monday disclosed records of its operations at the plant. They show that the reactor automatically halted operations after the earthquake. The emergency cooling system was automatically activated but stopped about 10 minutes later and remained off for about 3 hours until after the tsunami arrived. TEPCO says plant workers may have manually shut down the cooling system
    because pressure inside the reactor had dropped sharply from 70 to 45
    atmospheres. The system is designed to cool the reactor even if all external sources of power are lost, but the move to shut it down temporarily means that it did not fully
    function. TEPCO says the decision may have been made based on a manual to prevent
    damage to the reactor. It says if the system had worked, it may have had more time until the meltdown, so it will investigate developments leading up to the decision to turn it off and whether the move was correct.

      Probably beyond DBE. How do you design for a 8.9? However, even if DBE was 9, there is a likelihood some
      multitude of things failed. Offsite power is gone for the forseeable future as the grid is down. I think the weak
      link is the “median fragility of ceramic insulators in the electrical grid” NUREG CR 4910 (I have a copy from the
      old days from somewhere).
      With an 8.9, if a pipe support or snubber fails, pipe whip would probably cause a LOCA. EDGs must function.
      With 8.9 they may not for a whole lot of reasons. I have a hard time believing we are transporting water in to a
      facility on the coast. I hope the news article is wrong. I saw the story on MSNBC website and I know how
      accurate their US political reporting of our beloved President is.

      Japan Earthquake and Fakushima plants seismic design basis
      All: FYI
      The earthquake that hit Japan last Friday resulted in the ground shift of 8 ft ; i.e., roughly the site PGA of
      2.67g. The site experienced a peak ground acceleration that was more than 2.5 times the upgraded PGA
      capacity of the Fukushima units.
      In March 2008 TEPCO upgraded its estimates of likely peak ground acceleration (PGA) for Fukushima to 0
      .61g, and other operators have adopted the same figure. In October 2008 TEPCO accepted 1.02g PGA as the
      new seismic design basis for Kashiwazaki Kariwa, following the July 2007 earthquake there. Reportedly, the
      Fukushima units were upgraded to 1.02 PGA in 2009.
      By comparison, the certified designs of new reactors in the US are based on PGA of 0.3g.

      Jebus > The pressure dropped because the pipes broke from the 9.0 earthquake, 8 ft ground shift, and 2.67g PGA, causing a loss of coolant. The emergency cooling kicked in and pressure did not come up. They shut down the emergency cooling so that it would not pump all the coolant out of the reactor exposing the cores. Then the tsunami hit.
      Think about it…

      • Jebus Jebus

        Another thing to remember is you can have a 9.0 earthquake and only .5g PGA. A slow roller.
        And you can have a 5.9 earthquake and a PGA of 1.0g. A short sharp quake.
        There are many factors that seperate the two…

    remember what Benjamin Fulford said…

    he said the Japanese were threatened with a tsunami.

    he even said it in a scary very-serious; bat-shit-crazy way

    and he said it before the shit even came close to hitting the fan.

    you know it’s true but it went into the back of your mind where you had forgotten it.

    • larry-andrew-nils

      and the messiah, so i have heard, will have the name ben.

      so it’s all a big play-act, just like ron-paul who named his son after the rand corperation…; to laugh at us daily in secret.

      rand corperation who has engineered the next “final solution”

      ron paul is groomed to play savior of usa and i wonder if they are going to have much trouble making it happen.

      even this nuclear show could be all purposefully set up for us… i know this but don’t know if want to meditate on this hyper-level of crazy.

      alex jones ruined ron paul but that is good they are all in secret club against us. alex eats dinner with rockerfeller. yup

      remember on alexes show when rockerfeller said, “bring me some food” to alex closing the interview out with that line?… “bring me some food”

      and this is why jesse ventura is afraid to live in usa for the time when people find out he was in on a bad thing against the big population.

      remember “MEL FABRIGAS” was “george noory” in disguise reporting about the oil spill.
      …cause he’s cia, remember… duh

      also jeff rense is cia

      once cia always cia

      and all these nuke things everywhere are manipulation by these ones who think they have right over others to do their evil will.

      has to be manipulation. look how ridiculous/.

  • larry-andrew-nils

    yes rense you are so cia. you may have been hypnotised to think otherwise, but even you know, and even you have said, “once CIA always CIA”.

    xdrfox, I think it was you who posted a video which shows the seismic shock wave moving through the country?

    @ Darth….sorry lost your post.
    This is the La Garita Caldera..
    The volcanic/earthquake action all around the world is being looked at.
    The Psgah action is still on the board..especially when looking at the effect the Virginia quake had on Southern Cal…sorry but it is.
    PS. Not that any one cares but …I, in southern Colorado….just sayin…

    @StillJill..YES..the foundation of my house moved back and forth..the 5.3 was longer than the Virginia quake.
