Great wall of Fukushima?

A government panel has begun studying ways to prevent more radioactive water from accumulating at the Fukushima No. 1 power plant, including a plan to build underground walls around the damaged reactor buildings to stop groundwater from entering. […]

Proposals made by Taisei Corp. and Kajima Corp. Friday included building a subterranean wall around the reactor buildings using a claylike material.

Tepco considered building a wall on the mountain side of the plant after the March 2011 earthquake and tsunami, but abandoned the plan because of the risk that radioactive water flooding the buildings might be leaking into the soil. […]

    Yeah WHEN!!!!!

    • Jay

      Ya , you read my mind !
      And for a good reason : they dug sixty years ago the footing of the Golden gate bridge in the ocean in S.F. and they built the Palm Islands in Dubai but they can't dig regular water-tight Casings around the Plant ? In Two years ? What ? They even DIDN'T START ??

      Why do I hear the boys in the CIA 'coughing' copiously ?

      Did I mentioned they built the Egyptian Pyramids too ? πŸ™‚

      Whoever is at the Helm , he's not here on Earth … and that argument is based solely by one common human reflex factor : Self Preservation , specially of your children …

      • Jay

        … of course , do not pay attention to the basseles 'conspiracy theory' that under reactor # 4 there is a stash of nuclear material Undeclared , possible to built nukes , that;s why they are covering reactor 4 and that's why they need the groundwater to wash and cool the nuclear stush OR it will ignite and became visible …

        A pile of non-sense but makes for an exciting reading just as sci-fi does .

        Now coming back to Philip's Heat Anomaly find coming out of Fukushima since 3/11/11 …

          Points well taken, however…. By now, it does not even matter whatever secret illegal weapons program was going on there. Radioactive hell no longer cares WHY it is radioactive hell. The evil TEPCO people may have no more choices or options than if they were honest or cared whether anyone lived or died. They can neither fix this nor even contain it. This is just posturing. They know that they cannot do this, that it is not possible to do.

          Enough said about that crazy nuke-stash theory , let the Japanese govern-ment have the last argu-ment :

  • soern

    if they build this underground walls and even get Daiichi sealed, waste water levels will rise and rise….
    ….until there is a radiated lake, rising inside crumbling walls.
    There is no sensible long term solution in sight i fear.

    Decomission Spent Fuel and its Pools and forget about that molten cores cooling as those are surely gone already!!!

    • We Not They Finally

      "No sensible long term solution in sight"? There is actually no ANY "long term solution" in sight. Or short term solution! For the spent fuel above-ground either. But one of the more insane angles of this new ploy is, who gets to dig down into that radioactive hell to build ANYTHING? They would be building their own crypts.

      • soern

        they MUST decomission spent fuel at any costs.
        Actally groundwater is cooling those molten cores if at all.
        Japs SHOULD concentrate on ABOVE GROUND in order to prevent that FINAL STRIKE AGAINST ALL LIFE ON EARTH if SFP 4 comes down or starts burning for next 100 000 Years caused by a crack or an EQ.
        All what happened already is sad enough.
        Nucleocrats are maniacs.

        • We Not They Finally

          We also thought that humanity's last hope was for SFP4 to NOT collapse. By now, we are not sure that that has not happened already, or is not imminent, or that there is any chance of them knowing HOW to pull those thousands of fuel rods out "in time." We're still open to being reassured. We just suspect that this has doom written all over it.

    • PavewayIII PavewayIII

      Er… you can't 'decommission' a spent fuel pool, soern. TEPCO is making some kind of marginal effort to empty them for show, but they have no place to put that much spent fuel.

      Besides, it's TEPCO for cryin' out loud. You know they're way too evil and cheap to figure out long-term storage and PAY for it. My guess: They're going to secretly dump most of the spent fuel rods directly into the Japanese Trench 200 miles offshore at night. It's easy and cheap. The Yakuza has been getting rid of unneeded objects like that for years. Who would squeal?

      • jump-ball jump-ball

        Who would squeal?

        Certainly not the u.s. coast guard, who, surrepticiously, but with top-level gov't. approval over 30 years, dumped some 100,000 used batteries into America's bays, rivers and nearby offshore coastal waters, rather than incur the costs of safe battery disposal: THIS IS WHAT GOVT'S DO, WHO THEY REALLY ARE, HOW THEY SCHEME AND LIE, while they then fine you and I $1000 for littering a beer can…

  • We Not They Finally

    Oh, is that "claylike material" they propose for this the same as the clay sheets that were supposed to permanently hold the nuclear waste, but began to leak after just EIGHT DAYS?

  • TheBigPicture TheBigPicture

    They can't build a wall. Meanwhile, the island is being permeated with radiation, and will be for a very long time.

    • jump-ball jump-ball

      They could build more than a wall, namely a coffer dam, around the reactors, then lay a lower new containment floor, as was done under Chernobyl (by digging), then robotically push the corium into the new, watertight, ocean-free containments: it would be a massive, innovative concept, and could be done, as French Novarka showed the affected EU countries how Chernobyl could be contained, and might require 5 or 10 times the $1.4 BIL being spent to build the Novarka Arch over Chernobyl by 2015, to enable the u.s. company to begin the Chernobyl decontamination.

      A huge amount of money, $7 to $14 BIL, but just 1/2 to 1% of GoBombEm's 2013 projected u.s. annual $1.2 TRILLION, fair and balanced, social justice, budget deficit.

      But such an expenditure wouldn't "add to Abe Baby's Japanese "political base" by buying votes, as does Barry's u.s. deficit spending strategy (no-question food stamps for domestic Spanish illegal future voters, for example!), and therefore, at the expense of national and citizen health worldwide, will tragically not be proposed, or undertaken…

  • Jebus Jebus

    I think maybe the translation of Wall got messed up.
    Coudn't it have meant to be, "The Great Coverup of Fukushima"?

    • We Not They Finally

      I'll translate for you: "wall" probably means "crypt" for whoever starts digging. But no one will. This is just to create the illusion that they CAN do something. They can't.

  • Time Is Short Time Is Short

    They want to dig underground walls? The deeper they dig, the closer they are to the coriums, and all the massive amounts of radiation that is steaming up from them, along with getting closer to all the radioactive fresh and sea water flowing from those coriums.

    Not to mention digging large trenches in soft soil that is bombarded with earthquakes daily. The supports necessary just to get to the point where they can start to build forms will be gigantic.

    I can hardly wait for this to start.

    And why build walls anyway? Didn't some 'world class experts' the other day declare that everything held up fine, that there's no problem there? I hope they're the first ones in to measure for digging.

    I wonder: how far down to bed rock

    • Dr. Anne Lee Tomlinson Maziar anne

      There is no bedrock. Only porous sedimentary rock and landfill. Any wall they build will be purely cosmetic–to give the veneer of respectability when underneath is only rot.

  • Sickputer

    Big talk…little action.

    They had a window of opportunity the first six months just like the Russians, but the government of Japan is spineless. Now the three Elvis monsters have left the buildings and are far too deep for human intervention. Mother nature will resolve the radiation in a million years…humans will not survive another 500 years.

    Enjoy life if you're healthy, for tomorrow you may be in a death spiral like 125 million Japanese. They are casualties of technology out of control.

        "On the one hand, this retrofit is more difficult because there is extremely high radiation inside the Unit3 Reactor Building and it has been a very difficult and slow process to even remove rubble, let alonetrying to install adequate internal reinforcements. On the other hand, one might consider installingbuttresses to provide horizontal stability to the outer walls of Units 3 and 4.One might even consider surrounding these two buildings with a specially-designed gravel aggregate.Access to critical entrances could be preserved by laying down large sewer pipes to form tunnels.So the two tasks I need help with is:

        "Finding experts who might consider performing a preliminary assessment of the condition of Reactor Buildings 3 and 4 at Fukushima Daiichi based on ubiquitous internet photos and videoand other publicly-available structural information and seismic data.

        Finding experts who might consider writing a preliminary proposal on how to reinforce thesebuildings from the outside, as soon as possible.

        Finding experts who might consider the merits of filling the buildings with inter-filling, inter-locking pumice gravel or other quickly manipulated materials such as high-strength, highly-rigidfoams, bearing in mind that it only has to last long enough to
        stabilize the building for two or three years…."

  • End of the Road

    They know how to build an underground wall that won't crack when the next big earthquake hits 'em?

  • Cisco Cisco

    I don't think they're going to get a shot at that. Even if such a preposterous idea would work, they don't have to time. The site is rapidly being radiated due to the off gassing of the coriums, the spent fuel pools, and radioactive water containment pools.

    As the wind directions change, the entire site continues to be heavily dosed which exponentially raises the number of radionuclide disintegrations in situ.

    In the not too distant future, many areas of the site will be too hot for humans. I suspect it is now, but nobody told the liquidators.

  • nedlifromvermont

    they can dig down and perhaps even divert the groundwater flow; … with pumping, they may minimize the groundwater entering the basements … a coffer dam or site drainage scheme … they may take steps to minimize the amount of radioactive water stored for later treatment …

    they may do all this …

    but can we ever elevate the insanity of nuclear waste generation to the level of public consciousness …

    the cover up seems system wide …

    the cancers are a profit center for GE and their Medical Diagnostics Division …

    Japan was written off by Lehman Bros. bankers even before the 2007-8 financial meltdown …

    All the original nuclear promoters are long dead …

    Whom are we kidding?

      The boys of big industry, most of them with schemes going and gone way out of human control, remind me of the Keystone Cops. The irony is their creations ultimately take them away from what they set out to accomplish. Its happening in multiple industries and place but the story is the same.

  • ruppert

    I think that we all have to realize that none of the plans that have been proposed were ever seriously going to be implemented as Japan's economy seems to be worse off than the U.S.'s (if that's possible). The money is not and has never been there to do any of it. Japan is toast and is slowly making it's way around the globe. I personally feel that all there is left to do is to make the best of what time is left. We can grind ourselves down with anger or just accept that this can't be fixed and find some way to deal with it. I can't even imagine what anyone with children must be going through.

    Sorry for the fatalism but at some point you just have to acknowledge where this all is all going.

      That's my biggest worry, I have three children. I pray for their health and future constantly. I would do anything in this world for them. I guess that's what's so baffling to me is how anyone with any authority who have children could support this industry. Then again you read about phycos killing their families, same outcome just a different tactic.

      Dear ruppert,
      Agreed. Brilliant suggestions and difficult truths have been discussed here since the beginning. I believe in the importance of ENENews for many reasons, especially for newcomers and young people seeking information. We are here for you.
      Take good care.

    • Anthony Anthony

      That is not fatalism imo. You are absolutely correct in your suggestions and thoughts. Yes, indirectly we may have co-created these situations but we never set out to hurt ourselves and the planet as the people who have -have done. We cannot change the direction this runaway train has taken but we can get right in ourselves about ourselves. I personally think Fukushima is a possible fatal human error but the mercy of it has been that we are still alive. People right around it in Japan are still alive. It has never been more important to feel thanks for our lives and feed our own souls. I work everyday to keep free of heavy and negative thoughts. I wont give TEPCO my happiness. I appreciate your message.

  • jec jec

    Lets see a few TEPCO and Japan whoppers: Fukushima nuclear plant is in cold shutdown, which means plant equipment was functioning during and after 3/11 and is still working. Cold shutdown is a controlled stoppage based on successful insertion of control rods into the fuel cells. The fuel temperature is kept cool via water coolant process. Otherwise the system can not be said to be in cold shutdown..Right?. The fuel is still inside containment vessel, therefore cement still between corium and ground. No holes or the fuel could leak–right?

    So for these systems in cold shutdown, with fuel contained inside and in a stable low temperature, there should be NO WAY the groundwater could FLOW INTO the Fukushima nuclear reactor containment vessel and fuel cell areas–right? Its above the cement barrier..right? So how many rights make a wrong–or how many wrongs can ever make it right? Either way with doublespeak–TEPCO is just spinning words to save face. TEPCO needs to drink the groundwater from Fukushima, and shine with healthy radiation..

  • WindorSolarPlease

    We will see if this gets done, $$$$.
    At this point, what else can they do with this? This is an on going mess, it never stops.

    Not sure it will even work. Is the ground stable enough, what about the soil, can it hold? How are they, going to continually keep it cool without it blowing it's lid off?

  • RJ RJ

    I think they should start digging a football sized hole in the ground, line it with something and liquid nitrogen tubes and freeze the contaminated water. Jeeesh! I'm a mathematical dumbass and I can come up with this simple solution!

  • PhilipUpNorth PhilipUpNorth

    "plan to build underground walls around the damaged reactor buildings to stop groundwater from entering."
    It all depends, you see, on where the coium is.
    This might work well, provided Corium1,2,&3 is inside, or just below, Unit1,2,&3.
    This might not work very well, however, if Corium1,2,&3 are in the seabed, well out under the Pacific Ocean. Slant wells must be driven into the corium to map the location before construction on this project is begun.
    I find it remarkable that such a project is even under consideration at this late date.
    Lots of good ideas in the above discussion, ENEnewsers.
    "Great Wall Of China Syndrome" is just brilliant, lam335.
    Jay, here is the link to the sea surface temperature anomaly:

  • Heart of the Rose Heart of the Rose

    They filled the gashes and cracks inthe earth..running through Fukushima early on..covering the other open areas with steel plates..this however..does not make up for the destruction to the land itself caused by the earthquake..or the damage to the ground below the reactors caused by the original explosion..and the effect on the ground materials as the corium..makes its way downwards.
    Damage..and lots of it..
    A giant wall..in this type of geological situation and condition.
    It is not a viable solution..IMHO.

  • PhilipUpNorth PhilipUpNorth

    TEPCO wants to reduce ground water flow past the "lava tubes" left from the passage of Corium1,2,&3, Heart. The idea was to lower the water table, divert much of the ground water into the ocean, and thereby reduce the flow of contamination into the Pacific. Remember that this plan included the installation of a cofferdam along shore of the Harbor?
    Without building a cofferdam entirely around Unit1,2,3,&4, outside of these extraction wells, I do not think the present plan will be very successful.
    Instead, what we will have is an increase in air contamination through the surface fisures, and perhaps an increase in the instability of any remaining corium, without much of a decrease in groundwater contamination flowing into the Pacific Ocean. IMHO

  • Heart of the Rose Heart of the Rose

    I have dreams of ..lava tubes..not good.
    The cofferdam idea..a bit late..as below surface/off shoreline is also unstable..

  • Heart of the Rose Heart of the Rose

    Believe me..if a viable plan comes around..I'll be right here to promote it.
    Presently..the groundwater is being dumped into the sea..a horrible situation.

  • PhilipUpNorth PhilipUpNorth

    Agreed, Heart.

    Agreed, also, that there can be no workable plan if the corium has escaped under the sea bed.
