Reuters, September 5, 2013: Tepco also said on Thursday that the arm of a crane snapped while removing debris from the building housing the damaged No.3 reactor at the Fukushima plant. There were no injuries or damage to the building.

Tepco Handout translated by Fukushima Diary, September 5, 2013: the operator observed the crane gradually leaned. It is located on the west side of reactor3 building. A crack was found on the joint part for the main mast and jib.

  • We Not They Finally

    Is this how they plan on handling their insane Hail Mary of removing deadly fuel rods from no. 3 in November? Can't find a sturdy enough ordinary construction crane and we all die?

  • omniversling

    Just sucker-punch one of those spent fuel pools and kablooey…too too too too too too hard to believe, yet there it is…

    The parade of fools continue to march at Fukushima. A lone helicopter dumping a bucket of water into the wind a half a mile above three meltdowns , mud pies on the ocean floor to hold back the radiation, holding tanks on concrete slabs poured with no re-enforcing rod, duct tape to stop leaks, a statement by the government that "smiling people don't get radiation poisoning", beauty pageant for little girls who would promise to continue eating irradiated produce, building the plant on a porous unstable sandstone in the first place and now a crane being pushed beyond it's weight limit. If we had world leaders they would lead. Japan must hand over the planning and execution of stabilization and cleanup to more capable powers and stick to making pokemon purses. C'mon Obama, c'mon Putin, show your stuff. And get some American crane operators over there before they start moving spent fuel in November.

    • This would make a great reality TV show. The only problem is, it is way worse than any reality we would bother putting on TV, and those reality TV shows are all FAKE anyway, so it will never be seen there, or shown to the public.

      It is weird when reality is much worse than a fake reality TV show with people eating bugs, lying in a box with snakes, and doing some pretty bad stuff just for the chance for a little money.

      When will people wake up from this nightmare?

    • papacares papacares

      @jack – kwel avatar – you must have inside knowledge by your statement "now a crane being pushed beyond it's weight limit"

      please explain

      thanks

        papacares, here is how to calculate the load it can take. Fuku crane 600 ton

        • papacares papacares

          thanks n appreciate that – in the video it was impossible to see what the hook was trying to lift – jack had indicated the crane was being pushed beyond it's load limit – either the crane was making a pick it should not have been attempting or
          there was a structural failure in the metal of the crane – of course the metal making up the crane could be so compromised by radiation exposure now that any pick would be outside of the crane's ability to complete the operation – either way an engineer somewhere is not getting any sleep trying to determine what goes next

          • papacares papacares

            ok, now understand jack's comment, this is very strange – watching the crane collapse in real time it appears the operator was trying to make a very heavy pick far beyond the range capacity of the crane – but this is fuzzy because on the real time video the crane to the right does not move any at all while on the speeded up video the crane on the right is moving before, during and after the collapse – something is not right with these videos

            • papacares papacares

              last post – clearly after watching both vids several times this was either operator error or a hydraulic run-a-way on the cable drive – watching the workers scurry from the crane on the right means there must have been lots of noise and shaking – the crane must have bent earthward for 40 feet or more b4 collapsing and only then did it slowly fall appearing to be somewhat restrained on it's journey earthward

  • SteveMT

    TEPCO could have been removing this debris for years. They could have also developed a method to safely remove the spent cores from the storage pools in an organized and systemic way. The denial mode continue at TEPCO but now it's too late. Time's up. Unfortunately for us, from their denial shall come our demise.

  • DeSwiss DeSwiss

    Three words you never want to hear while you're moving things with a crane around nuclear fuel rods is: ''crane arm snaps.''

    Three words you are bound to hear from TEPCO eventually: ''we're deeply sorry.''

    :-/

    • weeman

      They better have back up systems on top of back up systems or leave them in place untill another method is developed and concentrate on shoring up building.
      Every task has to have three redundancy, just like space shuttle, that is common practice in extreme engineering.

      • THREE? backup systems? You have got to be kidding.. right?

        Well, let's see… let us look around. those backup systems have got to be around here someplace…. Yea, found them…

        Duct tape… check

        Baling wire…. check

        Garden water hoses…. check

        Chewing gum….. check

        See, we have FOUR backup systems, not just three.

        Happy now?

        • norbu norbu

          DR. – 1 more backup system FOR Tepco – #1 LIE ALOT.

          This fiasco couldn't have been dreamed up any better even by Hollywood. Every day now brings so many OMG moments… The entire plant will soon crumble from so many factors. Corrosion from salt water, Gamma ray metal corrosion / fatigue, leaking bolted single wall layer tanks that is radiating everything near it. Even if they weren't leaking they are emitting enough xrays through the thin steel single tank walls to fry your DNA. Feel for the workers killing themselves in vane. All they have done there to date is for not. What a waste. Goodbye Japan, Goodbye Pacific Ocean, Goodbye all things living. Have you seen the video of all the dead whales that just washed up on fukushima beaches. Hundreds and hundreds as far as the eye can see. Nothing of this in the mainstream media yet. Controlled little spurts now that it's really hitting the fan so they can say we told ya so. Here it is incase you have not seen this..

          Or the dead dolphins washing up on the Peru coast where they have already had mass shrimp dye offs by the billions.

  • Anyone want to start a company that will produce a dental device that holds your mouth in a permanent smile while you sleep at night?

    We all want to be protected from radiation, and if this Dr is correct, we must smile 24 hours a day, seven days a week..

    This device will ensure that you keep smiling even if you are sleeping.

    As a matter of fact, this device should be worn 24 hours a day by everyone. The Japanese government could pass a law requiring everyone to wear these and quit talking about Fukushima.

    Wow, it is SO EASY to solve all of these pesky problems…

    No injuries, good. Damage to the building? Seems I remember a pic or 2 that shows massive damage to the building. A bit of crane rubble would hardly make a difference.

  • MaidenHeaven MaidenHeaven

    Now I lay me down to sleep
    While gamma rays nibble at my feet
    Our future is now foretold
    By radiation levels 1000 fold
    In lead-lined beds we will rest
    After crushing our bones for the Strontium test
    So no more worrying about a thing
    For now it is time for the *fat lady to sing

  • The German

    Put a little tape around it and go on with removing the debris ha ha

  • Tape is good, but wrapping it with baling wire on top of that is better!

    Should hold for a year.. plenty of time..

    Move on, nothing to see here.

    Everything is normal and safe.

  • TheBigPicture TheBigPicture

    Very sad for all the workers. They shouldn't work there. It's unnatural, wrong, and not meant to be.

  • bo bo

    Ya… I would be bumbling a lot too if I had to work in a place with radiation that reaches lethal levels within hours… on just 10 $ pet hour…

  • captndano captndano

    oops! I hate it when that happens….

  • TEP-Joke does it again.

    these bufoons need to be removed from the job site. Then make them function as a zombie corporation whose next 50 years of profits go to the government to pay for the cleanup. Yes their stock value would go to nearly zero, no profits, no dividends.

    That is the penalty for effing up the Pacific plus

  • ShutItAllDown

    That'll buff out.

  • jackassrig

    Another thing that's troubling is the wire rope. Rope is made from small stranded wires. This allows the rope to flex as it travels over pulleys and sheaves. Wire rope unless the strands are teflon coated need to be inspected and greased to reduce the friction between the strands as the rope travels over the sheaves. The entire rope should be paid out on the ground and inspected for broken and worn strands. Lack of maintenance on the skeleton buildings and cranes will cause an accident. Salty environment and radiation is slowly weakening the site and machinery. One day TEPCO will try to make a lift and pop the cable breaks and down comes the load.

    Now I am finally register, I have been a lurker since the beginning, but had nothing to add. But now with "the crane broke" I can.

    i am not a crane expert, but do work with cranes.

    A good ref doc http://www.bigge.com/crane-charts/crawler-crane-charts/CK2500-II-Luffing.pdf

    1/ the crane was not lifting at the time, the hook and ball is up near the crane jib at the time.

    2/ The luffing boom fell, being hinged at the its base.

    3/ This means the luffing wire or the back stops have given way for the luffing boom to lower.

    4/ due to the slow speed it feel, it doesn't look like a catastrophic failure, but a slow feed off on the luffing boom line.

    In my opinion, the most likely cause, is the slow release of wire from the luffing boom winch. Why, most likely maintenance on the air or Hyd system of the winch and the locking dogs were not engaged.

    The break that Tepco showed happened after the boom fell, it did not cause it to fall.

    Why did TEPCO show miss information, to save face of its incompetence. But to me it shows the lengths they go to cover the truth.
