Jiji Tsushin report from Sept. 22, 2012 translated by EXSKF:

TEPCO announced on September 22 that a steel frame weighing about 470 kilograms dropped into the Spent Fuel Pool of Reactor 3 during the debris removal operation of the Reactor 3 building […] So far, there is no major increase in radiation levels nearby, TEPCO says.

According to TEPCO, the accident happened at 11:05AM on September 22 when [EXSKF: the crane operator] tried to grab a piece of debris, an H steel lying next to the Spent Fuel Pool on the 5th floor of Reactor 3 building and failed. The H steel slid into the Spent Fuel Pool.

­A huge metal beam was dropped into a spent fuel pond at the Fukushima Daiichi nuclear plant. Workers were trying to extract cement wreckage […] The crane boom accidentally pushed a metal beam into the pool from its casing, reports ITAR-TASS news agency. [Tepco] says the metal construction, 7.3 meters [~25 feet] in length and weighing 470kg, did not cause any breach in the cooling system, but could complicate further retrieve of spent nuclear rods.

        Hey GreenRoad: tell me, how do you expect ENE readers to respond to your 'super-solar-storm' piece:

        http://agreenroad.blogspot.com/2012/03/super-solar-storm-predicted-to-hit-2013.html#!/2012/03/super-solar-storm-predicted-to-hit-2013.html

        whenit asks "Did you know that an extreme solar storm hit Earth in the late 1890’s?", and "that this super solar storm (Carrington Effect) has been extensively studied"?

        Your extensive studies have missed the actual Sept. 1-2, 1859 date by only 40 years or so, and nowhere is it refered to as the Carrington "Effect", but rather the Carrington Event.

        Many of us know that passing on mis-information, is a component of
        passing on dis-information, and your 'super-solar-storm' piece, with flagrant, easily recognized factual errors and mis-labels, isn't passing the smell test…

          I'm going to pass the hookah over to you, jump-ball, and say that AGreenRoad has given so much to this community that two errors do not add up to disinformation, we all make mistakes, especially journalists, at places like the NY Times.

        • Dr. Anne Lee Tomlinson Maziar anne

          Posting links to informational articles is quite different from spreading mis-information. Links to articles informs readers as to what is being said. Writing the articles themselves may be mistakes or disinformation. Your jumping on the mistakes in an article and blaming AGreenRoad looks like you may be pro-nuclear.

        • jump-ball jump-ball

          'Extensive research' on ice-cores by other scientists indicates that 1959 Carrington-strength solar events have occurred on 500 year averages, while lower strength solar events such as the May 13, 1921 flare that burned the New York Central Railroad signal and switching lines and equipment in N.Y.C., and burned down the central control building, show up in the ice-core samples at 75 year intervals.

          I think that being as specific and as accurate as possible in describing past events, is essential to any discussion or supposition of future recurrences.

    As I understand it, fuel rods are extremely fragile, requiring specially trained personnel just to handle them. From that, I would expect anything heavier than a brick to cause major damage.

    • AGreenRoad AGreenRoad

      What fuel rods?

      Something happened to the fuel rods after the four part explosion, which emptied both the fuel pool and the reactor… and that is not a nice something, or a little something.

    How much coolant would be displaced by something weighing that much?

  • Can to remove scrap metal from the reactor 3 can use these electromagnetic grippers?
    Also for attaching various devices and cameras probably would be useful..

    What happens after the drop/slip?

    TEPCO will just obfuscate any events by giving out incomplete information, you'll never no whats going on by TEPCO reports. In fact, I am surprised they release anything about this mishandling of debris.

    I would like to know if riggers are on floor of Unit 3 connecting cable for the crane hookup. I understand the cranes are operated remotely: Does the crane operator have a remote control to use while standing somewhere in the area being worked on to control the crane boom or are cameras mounted on the cranes to operate from video screen shots or both?

    Some outside help and advice would not hurt from world class construction companies. You would think TEPCO could secure all the loose or questionable beams and rubble with cables, at least connect the rubble to itself before attempting to move something.

    It's only remnants of deadly nuclear fuel and contaminated debris being worked on or around like a game of radioactive pickup sticks.

    Still would like to know if they pulled the green refueling machine that had one leg in the pool out yet.

      Razz,

      I saw a video or some pictures of the operators at work.
      They are operating remotely from a bunker using live video feeds. They are using hydraulic demolition shears and clamshell buckets to shear and grab the materials because they require no human presence in the work area. I do not believe that any riggers are in the work area to coordinate the picks, it would be too dangerous to be present for several reasons. Having riggers would be the ideal way to cut and lift the debris, but at great risk for the workers doing the work.

      Like you said, at this point it's a deadly game of pickup sticks. Tepco knows how high the risk is, so they are hinting at the difficulties now. Literally every piece you pick will alter the center of gravity of the remaining debris pile. Removing all of the debris without dropping any is virtually impossible.

    BTW, magnetic pickup is hard to control and is going to attract anything metallic in the immediate area. The magnet head would soon become overly radioactive from contamination just like most of the machinery and tools (and workers) will become dangerously useless.

    • It's dangerous, it's like that big steel thing is free on the edge of the pool and gently hit falls into it, which can cause large and dangerous consequences …
      It is an electromagnet, you can easily control, adding, or removing current when raising should not be continued for various reasons. But surely all these things that are loose, this can be easily collected.
      Head, may be radioactive, because no one does not have to operate in close proximity to, and besides, you do not need so much, and you can save some of these heads have to use any … But you have to know something about collecting scrap metal, not just the cleavage atom …

    IF there is water on the camera lens then we can all just call it what it is, intentional disregard, stupidity, or outright laziness. Pick one or more of the above.

    A camera could easily be sheltered from the environment and still be positioned to do it's job. The information that camera provides is a critical link to the reality of what is happening there, but they don't seem to give two shits about providing accurate information.

    There should be more than one camera, focused on various viewpoints, from various elevations. The entire thing is a shoestring operation.

    Another thing, where the F is the US Government? They've spent a national treasure and destroyed the Constitution to "protect" us from "Terrorism", but imo Fukushima just shows how that is all just a bullshit, nothing more than a self serving bureaucracy. Call it the military industrial complex. They have no intention of protecting or informing us, or even treating us like adult equals. It's about the money. Not you, not me, not the children, not the future. Money, power, and control.

      "I was honored when you asked me to join in celebrating Howard Zinn’s life and legacy. I was also surprised. I am a journalist, not a historian. The difference between a journalist and an historian is that the historian knows the difference. George Bernard Shaw once complained that journalists are seemingly unable to discriminate between a bicycle accident and the collapse of civilization… "

    "7m and 470kg of steel frame dropped into the SFP of reactor3, “566 fuel assemblies are in the pool”

    Posted by Mochizuki on September 22nd, 2012 · No Comments

    About 11:05 of 9/22/2012, Tepco dropped a steel frame of 7m long and 470kg into the SFP of reactor3. 514 assemblies of spent fuel and 52 fuel assemblies are kept in the pool.

    Tepco was removing debris by the remote controlling crane and dropped it into the pool mistakenly.

    The steel frame was 30cm×20cm×7m, 470kg. It was dropped from South-East side.

    Tepco states the radiation level did not change, the dosimeter set 2m above the pool did not measure any change in radiation level either. Water level and the temperature did not change.

    It hasn’t happened that such a large material dropped into the pool.
