Multiple assemblies ‘deformed’ in Fukushima Unit 4 pool — One “bent at a 90-degree angle” — Tepco: Mistake occurred when handling the fuel… 25 years ago

Published: November 13th, 2013 at 1:56 pm ET


Yomiuri Shimbun translated by EXSKF, Nov. 12, 2013: On November 12, TEPCO disclosed that there were three fuel assemblies […] in the Spent Fuel Pool of Reactor 4 […] that were deformed and would be difficult to remove.

Fukushima Minyu translated by EXSKF, Nov. 13, 2013: According to TEPCO, one of the damaged fuel assemblies is bent at a 90-degree angle [literal meaning: bent in the shape of a Japanese character “く”; actual angle could be less]. It was bent 25 years ago when a mistake occurred in handling the fuel. The other two were found to be damaged 10 years ago; there are small holes on the outside from foreign objects.

Reuters, Nov. 13, 2013: [TEPCO] will as early as this week begin removing 400 tonnes of highly irradiated spent fuel in a hugely delicate and unprecedented operation fraught with risk. Carefully plucking more than 1,500 brittle and potentially damaged fuel assemblies from the plant’s unstable Reactor No. 4 is expected to take about a year […] If the rods – there are 50-70 in each of the assemblies, which weigh around 300 kg (660 pounds) and are 4.5 metres (15 feet) long – are exposed to air or if they break, huge amounts of radioactive gases could be released into the atmosphere. […]

    "It was bent 25 years ago when a mistake occurred in handling the fuel. The other two were found to be damaged 10 years ago; there are small holes on the outside from foreign objects."

    Tepco can't do a damn thing right, can they?!

    • weeman

      I was thinking about that, you had a problem 25 years ago and since then you have done nothing about it and since then no new technology available, if I was a engineer at the premises that would challenge me, it's not going away and if you want to leave your mark, what better way.

    • We Not They Finally

      The only thing I want from TEPCO is ritual suicide.

  • Alpha1

    Please ENOUGH we need to remove TEPCO and Japan needs to be evacuated period this is genocide and what we are doing is a crime against first the Earth and secondly the rest of the earths creatures then man. We need to be removed from this planet if we can not get a grip and do something now then we should become extinct with the already 1000's of species in the pacific ad the planet. We are our own destruction and do not deserve to be the tenders of the earth.

    How can anyone say anything but the truth here we are all dead in a short amount of time our own chromosomes will be so bad that there will be no new generation of man. We can hope that we can turn into X men but be real. We are about to become mush and the earth is going to be alone without anything on her for 1000's of years. ELE yes extinction level event is accurate. The Fuk U Shima facility is leaking 10 Hiroshima's an hour into our atmosphere and the equivalent of 100 Chernobyl's a day at this point and we are still speculating and want to do studies to see the long term affects what are we fucked in the head!!!!

    There has been the equivalent of 1.3 trillion lethal doses of radiation dispersed a day now is like 100 years and soon it will show when we all start collapsing even the draconian lizard pricks in office…

    • We Not They Finally

      Alpha1, am really really depressed reading your probably really really accurate sum-up….

      Three days before this happened in 3-11, husband sitting at kitchen table, just kept saying, "Something terrible is about to happen. It's the beginning of the end." From Day One, we knew it was an ELE. We just could not grasp the real horror of it all at once.

      God help us all. May we be compassionate dignified humans for as many years we are given. In some larger picture, it is perchance the "draconian lizard pricks" (as you put it) who will not be getting the last say. There HAS to be some world better than this one.

        I appreciate you and all that are here, I am and have been a Nuclear engineer. I retired when I got the call from Bachtel Jacobs to go do hot work at Fuk U Shima. I have spent the last 2.7 years working to find alternative technologies to slow down radiation exposures in the home and as well find ways to stop free radical exposures in the blood stream and heavy metal exposures from destroying cell walls. I have found after beating nuclear blushing cancer several recipes that will protect the cell from radiological poisons. I have posted it in many places as I have been looking for like minds that want to [protect their children] so to speak.

        I can tell you we have started several things with coming to our lord. Nothing else exists there is us and the creator whatever you want that to be. So we have things going on that is a cure for the cause. You are welcome to check us out on FB we just opened that up and as well as few other things.

        My spouse said the same thing when he saw the first explosion and he is a chemist so he knows much more than I do but he just said this is really bad and then when the other explosions happened he said we should get ready to head south as we both went through the TMI debacle and were not going to listen to the govt. Once again it's mass confusion and misinformation and Tepco should not be doing this alone, this should be an international mission with the best and brightest our planet has to offer. IMHO

          "Even the very lowest levels of radiation are harmful to life, scientists have concluded in the Cambridge Philosophical Society's journal Biological Reviews."

          • UnclearOptions MaryM

            "Mousseau hopes their results, which are consistent with the "linear-no-threshold" model for radiation effects, will better inform the debate about exposure risks. "With the levels of contamination that we have seen as a result of nuclear power plants, especially in the past, and even as a result of Chernobyl and Fukushima and related accidents, there's an attempt in the industry to downplay the doses that the populations are getting, because maybe it's only one or two times beyond what is thought to be the natural background level," he said. "But they're assuming the natural background levels are fine."

            "And the truth is, if we see effects at these low levels, then we have to be thinking differently about how we develop regulations for exposures, and especially intentional exposures to populations, like the emissions from nuclear power plants, medical procedures, and even some x-ray machines at airports."

    While we are focused on Fukushima #s 1…2…..3……4 what about 5 and 6 which are in "cold shutdown?"

    What about the other dozens of nuclear plants across Japan and their spent fuel pools?

    Just where IS all this radioactive crap going to end up?

    Moving the fuel rods, bent, mangled, or otherwise, out of SPF#4 means they have to GO somewhere else.

    For that matter can anyone come on this forum and PROVE to me and others that ANY nuclear waste
    is safely stored anywhere?

    I think not. That is the problem. Not just SPF#4 but all of it everywhere.

    To generate toxins that should never ever be released into our fragile biosphere is becoming more and more of a stupid idea.

    The reality is we have poisoned the earth all over.

    If folks realized how dire things are, there truly would be panic.

    It's the technology that needs to go the way of the dinosaurs, not life on earth.

    The hubris of man (not woman!) knows no bounds.

    • DavidStuart DavidStuart

      Well said, Nick. The entire nuclear fuel chain is evil and toxic from beginning to end, but nobody thinks about how and where to store spent fuel and has no consideration for future generations for thousands of years. As long as they don't have to worry about it in their lifetime, then it's out-of-sight, out-of-mind.

      TEPCO started removing fuel from 5 and 6 a while ago. In fact they were in the process of doing that during the last 7.1 earthquake which makes me wonder what the true status of the facility is now. As they always seem to wait until they can no longer hide the truth but truth cannot hidden only delayed.

    • sunpower

      Bingo, Nick. The magnitude of industry stupidity is the elephant in the room.
      Removing fuel rods from one fuel pool to another is not a solution to long term storage at 400 NPPs worldwide or even just at Daiichi. Fuel rod transport schemes solve so little compared to intractable fallout from the Daiichi meltdown/zirc fire plumes registered by NASA or compared to what is always left there on the sites ungrouted, uncovered often, regularly dumping radiation into the ocean spreading it far and wide. I'm not impressed Tepco could fleece the slaves out of another new Hitachi crane, set it up and run off a fuel transport show…all theatre when they nuked Japan and the world and show no sign of ever burying their huge mistake in power grid production.

    • Siouxx Siouxx

      Nick, if one good thing has come out of this disaster, then it must be a better understanding of how our planet has been and is being systematically destroyed by all-consuming greed and corruption and for centuries. A multitude of industries, nuclear included, were conceived with the sole idea of short-term profit and inherent disregard for the impact upon either health, wellbeing or the environment. I just hope people begin to think outside their bank-funded education system and ask themselves what they are doing to remedy this situation by changing their own habits of consumption. It remains to be seen if Unit 4 Fuel pool is/has or will be the finale which brings down the curtain on the arrogant, self-destructive human race. If only the plants and animals, birds and insects et al could continue to survive, they would make so much better and much worthier caretakers.

  • Shaker1

    I would have liked to have seen them make some effort to create an atmosphere controlled enclosure when they built that structure over the building before undertaking this, purging and backfilling with nitrogen. It may have required breathing apparatus for those working inside, but it would greatly lessen the possibility of fire and release into the atmosphere in case of problems. I could also envision an apparatus in conjuction with the crane that could ensure anything lifted into it would never be out of water even free from the pool. Think about a water bottle in a water cooler, how, as long as the bottle doesn't leak, the water in the well beneath keeps it full. Place a small lifting device (could even be simple cable and hook) inside the bottle, and a 'cap' is actuated and held watertight with lifting, by the bottom, of the apparatus from the water by the larger overhead crane.

    The fact that there are compromised assemblies and that some of them have been in there for years without horrible release should tell one that avoiding questionable assemblies would have to be done. But if they aren't lying about the contents, I would be more comfortable with retrieval of the bulk of the contents, if that can be accomplished. Have you ever known when you undertake an action that you're going to get hurt? I have. The choice then is to minimize that hurt. I know I'm talking out my ass, but, damn, sometimes cowering in the corner simply doesn't get it done.

  • amberlight amberlight

    A "mistake" occurred while handling the fuel, but we fixed it by ignoring it. Out of sight, out of mind. Oh, and "foreign objects" fell into the secure, well-protected fuel pools. It's a good thing dead rodents are soft and furry or there would probably be more than a few "poked holes."

    This farce is just about the worst comedy act I have ever been forced to sit through…

  • PhilipUpNorth PhilipUpNorth

    "…exposed to air or if they break…"
    The fuel assemblies in SFP4 are probably not going to be exposed to air.
    But some are likely to break during fuel handling.
    All have been damaged by exposure to seawater.
    Some may have been, we have been told, damaged by fire.
    Some may have been damaged by falling debris.
    Some may have overheated when the water in SFP4 apparently leaked out, or boiled off.
    People of earth, the upcoming months are going to be such fun! 😉

    • Alpha1


      Sincerely honestly salt water does not damage fuel cells they are made from Zirconium and Carbon Fiber in some cases they are made from Alumantium I am sure that no one has heard of this but they are man made alloys that do not rust and are harder by 1000 times that of steel.

      So how could ocean water ever damage them??? they could not unless they are taken and blown up HMMMMMMM!!!Hydrogen explosion wow!!!

  • Could be classic TepGab way of admitting damage to spent fuel. Next week they will report explosion damaged some rods but there is no cause for immediate concern.

    Dry cask storage parking lots are springing up all over the United States, beginning in 1986.
    There is a plan for just such a parking lot for dry casks at Fukushima.

    • moonshellblue moonshellblue

      Dry casks are to expensive as my spouse has said they should have been dry casking the common spent fuel pool to lessen the damage if reactor 4 goes critical but TEPCO has been busy handling the onslaught of water and shoring up Reactor 4 but why they are trying to decontaminate areas makes no sense to me as every spring pollen will just coat the ground they have removed. So now they have huge areas just covered with green tarp. I can still see that picture it's unreal how much nuclear waste they have accumulated and for what, to do it all over again. It just doesn't make sense to me.

              Thank you VERY much for pursuing this. We hadn't been checking rad readings in our area until recently — Albuquerque — then we discovered that the BASE rad reading is about 100 CPM, but it is continually spiking up. The last spike around October 27th was 500+!

              But then we looked up other cities where the rad monitors were apparently completely turned off — Seattle, Portland, Honolulu, other cities. We could only "guess" that since the rad chart "only" went up to 1000 CPM, that if these recorded higher, that might have activated a shut-off valve.

              Anyway we are about to purchase colloidal zeolite, which was recommended for eliminating free radicals. But if you are developing something more effective, great! Keep at it! We're also into baking soda, which alkalizes the blood, the opposite on what cancer thrives on. And staying away from sugar.

        • Ontological Ontological

          Einstein said "This is one hell of a way to boil water." He meant that sarcastically as he knew Edison had seen Tesla's diagrams he made for the generation of meter free power. Tesla was a humanitarian, and wanted the brightest, best and safest future for mankind. He found out the greed here is too overwhelming. A good read is "The Fantastic Inventions Of Nikola Tesla. By Nikola Tesla. His idea was to use a plutonium thermocouple, made to power a huge Tesla coil tower, that would force great lightening like bolts of electrical energy into the ground. His dream was a world of fluorescent technology and wireless energy transmission for "free". All one would have to buy is materials for building equipment to harness the energy like ground coils and power converters. This along with solar, and hydro power would have made planet Earth a paradise with no ugly electrical transmission lines. Sigh what a grand illusion that was. Issue was Edison only remembered Tesla's way to make the plutonium, the BWR we all know is fatal to life ecosystems. Nightmares like Fukushima, TMI, Yankee, San Onofre Nuclear Generating Station, which btw is owned by Edison of S. Cal. (SONGS) like, "GE we bring good things to life."

Same talking points over and over without room for any sort of talk about radiation poisoning.

    I for some reason do not think this situation is going to end well. I just wish this fuel removal was going to be televised so that once I see one of the fuel rods coming apart upon removal I could book my airline ticket to South America! My question is why cant the fuel pool be removed all at once and placed in concrete or some other containment device? Hopefully the Japanese government is closely monitoring the developments here as I don't trust TEPCO one bit!

    I just want to know when these missing coriums are going to be located and dealt with. I assume that even once they are located that they are just going to remain in place as we currently do not have the technology available to move them anyways…. God help us here!

  • FXofTruth

    So these "deformities" were caused years ago in the BEST technically accurate environment possible. Now, we have the WORST technically accurate environment possible to remove these damaged rods…and some people actually believe that this endeavor is going to work?

    I see MANY, MANY nominees for the latest Darwin Award!

    But this hopeless undertaking qualifies all those involved…for the "Darwin Award of the Millennium"! Only self-destructive men can dream up the most dangerous power source technology and then try to undo the damage using stupidity and fingers crossed.

    This looks like the mine removal method used in India. Hundreds of men in a long dance line, poking the ground with long sticks! Hey, it worked in Iraq…you could always tell immediately when they found a mine, bodies parts went flying through the air. So, poking around the broken nuclear fuel pool is just one giant mine and when they find a problem…everyone will know it immediately!

  • pjrsullivan

    While many seem to ascribe the building of nuclear power plants to greed, might there actually have been other reasons?

    As the world is now facing grave environmental damage and with it, the risk of mass depopulation due to a variety of radiation induced illnesses, might this result not have been planned all along from the earliest days of nuclear energy?

    Rather than an accident, might we be seeing the outcome of a well intended dirty bomb attack designed to remove the mass of the human race from the surface of our planet? Might we be living in the days of a well planned widespread planetary genocide and not have realized it yet? Many commenters on this site have revealed the difficult truth to us.

    Can we not appreciate that we must take the power to issue our money away from the central bankers to fix up our world?

    To get this power of the purse in to our hands, we must STRIKE THEM OUT. Must labor not give us a hand?
