NHK: The leaked water contains more than 100 million becquerels per liter of strontium and other radioactive matters, enough to cause burns if in contact with it for long enough.

At 5:00 in

Tepco: The design was meant to prevent leakage completely. We believed the facility would never cause any leaks.

At 7:15 in

Expert: This sheet made of bentonite is 6.4 mm thick, that’s the same Tepco used outside the reservoirs. The tests show a water leak occurring on the 8th day.

At 12:00 in

NHK anchor: As we saw in the report, the polyethylene sheet was thought to be leak proof but it wasn’t. The bentonite sheet was only 6 mm thick so it leaked after only 8 days […]

NHK reporter: In a nutshell it was over confidence.

    TEPCO continues to rely on standard industrial materials and systems. The materials and systems used by TEPCO have, for the most part, been designed without "must stand up to intense radiation" being used as a design criteria. If you use the ability to stand up to high radiation as a design criteria, you will find very few standard industrial materials up to the job. 99/100 of the highly radioactive water that has been used at, or has flowed under, the Fukushima Diiachi NPP flows right on into the Pacific Ocean, where it will remain potent virtually forever. Who are you kidding, TEPCO?

    • Jay

      But Philip , look at what Asahi dug from Geneva to show us that the 62.7 % of Japanese voters did bring in a nuclear-friendly government , who now says This :

      From Asahi :

      " … GENEVA — Despite being the only nation to have suffered atomic bombing, Japan has again refused to sign a document that describes nuclear weapons as inhumane … " .

      The only reason why they would say that is if Japan has being building nuclear weapons in secret …
      Philip , what do you think : all that polution from just three coriums ? Do the nubers add up ? Thanks !

      • PhilipUpNorth PhilipUpNorth

        Good point, Jay.
        However, Tame Nuclear Reactors are built to boil water at relatively low temperatures.
        Rogue Nuclear Reactors begin at 3,200C during meltdown. Criticalities can drive their temperatures even higher during plant melt-through. You have brought this up before, Jay. So I ask you: Do the math to calculate the energy in MW of Corium1,2,&3(MOX). (Warning: The figure for MW of electricity generated by three fuel loads in 3 nuclear reactors over one fuel cycle is not the correct answer.) My guess is that the numbers do add up to what we see in the NOAA SST Anomaly maps.

        Your guess, I take it, is that Japan lost a lot of its secret nuclear bomb making materials at Fukushima, Diiachi, and that these additional non-power nuclear materials are what is flooding the Pacific Ocean with heat and radiation?

        So, I offer my time for this project. Let's capture some data, and come up with a number for the energy observed as the ocean heat anomaly. (Or use the criteria of your choice.) We can then work backwards to the energy potential of the fuel in the reactors on 3/11. Posts should be on General Discussion Thread (Nuclear Issues.) I can begin Monday.

        • fireguyjeff fireguyjeff

          What is missed by most people is that the reactors were running around 35% efficiency ON A GOOD DAY.

          And that is just operating….not accounting for the energy spent mining and processing all of the fuel and infrastructure!

          Some one correct me if I am wrong on this one.
          The cooling towers are needed for a reason!…..a lot of waste heat.

        • Jay

          Philip , you're right on ! I rely on your greater ability for scientific calculation by far as you demonstrated already , so I am all for the ocean heat anomaly esstimation to help establish the real nuclear 'load' that it is Washed by the ground water .

          Caution , dear Philip : 'they' already manipulate and 'fudge' the current maps by pretending to do Data Correction . The AMSU web site carrying the best algorithm to display microwave emmission was closed a month ago !

          Our Public scientific resources are taken away from us or rendered unusable , a Disgrace to certain 'scientists' !

          Back to the Mistery nuclear load , let's read between the lines here : if there is indeed such a secret stash it means that the engineers will not alow the ground water to be interupted from cooling that stash , Otherway the nuclear fuel will ignite with Both eye site and instrument obtainable visibility , which of course will raise questions .
          So not diverting the ground water OR replacing it , it should be a very serious indication …. what do you think ?

          • Jay

            … so , eventhough I am not an engineer , I see the solution to the mistery nuclear load ( if exists , which I don't know so don't shoot me , Mr. Mossad ) , as both Covering it to eliminate Air radiation dissipation , And , no choice , to use the ground water Near By ( the Plant is built ON it ) to cool the stash , NO CHOICE !!

            So , the Big So , WHICH nuclear reactor ARE THEY COVERING RIGHT NOW ? Lucky guess , No. 4 … just as , by coincidence , most of the ground water is flowing under it , 'Cough' ….

      There really wasn't an effort to deceive anyone, Philip. The design criteria was "must stand up to intense bonuses for directors".

      Now – I'm no clay engineer – but it looks like the performance was outstanding and well within specs. Remediation contractors in the U.S. are intensely interested in the leaky clay and plastic sheeting technology. They believe it may offer an extremely profitable Hanford solution. Samples have been delivered to Sandia National Labs for analysis and Obama has already pledged over $3B of taxpayers' retirement accounts to fund clay jobs.

      Bechtel already owns IP rights in the U.S. for it's Plastwich Sieves – gigantic in-ground bathtubs for storing nuclear waste. Bechtel's Plastwich Sieves use layers of clay and leaky blue plastic. They are suing TEPCO for misappropriating Plastwich, claiming that TEPCO's use of leaky black plastic is essentially the same product.

      In a related lawsuit, Bayer A.G. is seeking the recovery of billions in royalty fees from clay users like Bechtel and TEPCO. Bayer owns the rights to all naturally-occurring clay compositions and requires anyone who uses clay for any purpose to pay an annual maintenance and support fee. It is watching the Bayou Corne situation closely and expects to file suit against Louisiana soon.

      • PavewayIII

        It is astonishing that Bayer owns the right to all naturally-occurring clay compositions!!!!

        Can you please provide me a source for that?

        • Sickputer

          Friday Follies…Paveway is just joking… 🙂 All of the post was pretty detailed nucleocrat satire.

          • PavewayIII PavewayIII

            I was kind of waiting for someone else to watch the video and point out the TEPCO's latest con. Am I really the only cranky skeptic left here?

            I don't have particularly high expectations of NHK anymore, but they actually did some critical reporting this time. No journalists here noticed that? Maybe Quill is the only thing reading ENENews today. I may was well just post insanity until the admin boots me.

            OK, pay attention tin-foil hat nutters: watch the video and pause around 20:33 where they're showing the groundwater plume's path. Daiichi was build on a fluvial fan (the mouth or delta) of an ancient river. Dig down and there's sand and clay layers deposited there millions of years ago. That's bad for so many reasons, but let's consider the groundwater problem.

            The reason the reactor and turbine buildings are filling with 400 tonnes of groundwater a day is because that's how much water was always flowing through that section of the aquifer at that level. They knew how much and which direction.

            Look at the plume path and monitoring wells. Notice how many are upstream? Notice how many see the plume?

            Follow were the radioactive plume is emptying into the ocean. Hint: it's off-site.

            NHK is trying to show you that this was all an elaborate ruse to build leaky reservoirs that WOULD dispose of all that untreated water through the aquifer and directly into the Pacific Ocean.

          majia: The clay rights reference was mocking the way corporations have twisted the legal system to own everything. I was looking for a link to offer as an example, like owning air or water. Google was kind enough to return this link:

          Privatization of municipal water supplies isn't the exact same thing because there are alternatives. It's next to impossible to use those alternatives if you live in a city of any size.

          Fukushima Diary has a post today about a Japanese Blogger having their blog taken down by the provider. The censorship is related to posts critical of water privatization in Japan. Two weeks ago, Deputy Prime Minister Taro Azo (mini-Abe) reiterated a desire to do so at a Center for International and Strategic Studies conference.

          There's also Bechtel's failed attempt to extort a few pennies from the poorest Bolivians a decade ago. After jack-booted thugs killed some protesters, Bechtel gave up and left. But not before suing Bolivia for tens of millions.

          How far away are we away from something like Bayer's clay user fees? It's only satire *today*.

          The liquidated blog was on a Japanese site called Ameba. It's nearly all in Japanese, but I dug up one English blogger that explains the site better:

          Fukushima Diary's brief summary of the situation is linked as usual at the bottom of this ENENews page. Direct link:

          Everyone here should be worried about the situation. The internet is a threat to governments if they can't totally control the content. The U.S. only blocks a few dozen overseas sites last I heard. They'll settle today for CISPA – unfettered access to any kind of private account you have anywhere and logs of all your browsing activity.

          Tomorrow, it will only be web sites they permit to exist if they publish 'approved' content. And that will only be *if* you get permission from the government first because they'll claim internet access is a privilege, not a right.

          DHS Internet Cop (on your screen): "Citizen browser: Pull over and go offline! Where are you linking to in such a hurry? Let me see your Browsing License and Computer Registration, please. Wait in front of your keyboard while I check this out…"

    I'll just dig a deep hole and line it will plastic garbage bags then fill it with water. What could possibly go wrong?

    All 7 liner pools are now considered unusable. Test/monitoring wells drilled by TEPCO are located in areas that favor not finding radioactive contaminated water leaking from the failed pools, outside experts claim the need for new well in other locations nearer underground water flows and exiting water tables.

    The bypass idea to sink wells upstream and pump groundwater up and discharge away from the site is estimated to only remove 1/4 of the groundwater contacting the melted cores.

    The bottom of the failed ponds were built 3 feet below groundwater level (#2 pond was used as the example), a direct leak path into the water table.

    I am not sure how the situation could get much worse unless a large earthquake leveled the entire site…which could still happen anytime during TEPCO's 40 year cleanup plan.

    "In a nutshell it was over confidence."

    That pretty much summarizes the entire industry.

    Shut the Nuclear Reactors down today!

  • dosdos dosdos

    It's actually a pretty good technique for sealing a pond in porous sandy soil areas where there are no earthquakes. I think the salesman who sold TEPCO on the idea forgot to mention how earthquakes don't sit well with the liners.

    • moonshellblue moonshellblue

      Radioactive isotopes I'm sure can wreak havoc on these liners and the harsh climate due to the location. Could they use a closed loop system thus recycling the water? A foolish question but i always wondered why they have not used such a system to limit the massive amounts of water used to cool the corium. Ahh, I guess it could cause fissioning? Not sure if they could filter it somehow or even if that is feasible. They claimed Areva developed a method for removing some of the contamination from the water. It just seems like such a waste of water as it is just leaking into the ground and ocean thus causing even more problems.

  • moonshellblue moonshellblue

    Good explanation about current system being used and reasons why leaks occurred.

  • jec jec

    I am sure if we used this technology to prevent septic tank leaks..we would STILL be in jail..but let a big company or a government trying to save face or hide its activities..thats just fine..go ahead..

    What might make a difference is to ID radiation from a human body..and request safe removal of the product. In other words, TEPCO has to fund the de-contamination of their victims..something no one has done yet..

    • jakester1972

      Yeah, If my 275 gallon oil tank in my basement leaks, I have to pay 200 grand to excavate all the soil around my house. But it is OK to dump Fukushima water on the ground and in the ocean. I would rather eat oil, thank you very much.

  • TheBigPicture TheBigPicture

    Scientists and engineers of the world must try to save that island.

  • Ancient Voices

    This 40 year plan is plain idiocy. Of course anything could happen to make things worse, indeed they already are. What a joke.

  • wetpwcas1 wetpwcas1

    Insane is a light word to call these ppl!

  • The Blue Light.

    No Surprise's here. Job, get rid of the contaminated water. Job done, we'll let it leak into the ground, success. The thing that leaps out at me from this article is the usual one, MONEY. These reservoirs have been built on the cheap.
    On another matter, I think Japan, South Korea and several other developed countries can claim, with a straight face, that they have no nuclear weapons. If you change the question to "do you have a stockpile of components that could be assembled into working warheads" then I think the straight faces would be gone. Few people know this, but I was involved and can guarantee it has the truth. Even peace loving Sweden handed over 20+ warheads (fission, boosted fission and boosted fission/fusion) to the UK and USA after the end of the cold war.
