Japan Times, Oct. 19, 2013: [...] The government has been notably slow to act on several occasions, which has even left pro-nuclear advocates scratching their heads in bewilderment. [...] Presuming Tepco is able to control the spread of contamination beyond 2015, it would still have only scratched the surface of the issue. The mammoth task of removing the melted nuclear fuel and debris from the reactors lies ahead. [...] removing the spent fuel rods from the reactor 4 cooling pool [...] merely puts Tepco and the government on a collision course with the hitherto great unknown: finding the melted nuclear fuel [...] Nuclear fuel inside reactors 1, 2 and 3 is believed to have breached the inner containment vessels and accumulated in the outer steel containment vessels — what experts describe as a “melt-through.” Assuming the reactor pressure vessels are submerged [it] still won’t help much in figuring out where the nuclear fuel is located. [...]

Michio Ishikawa, president of the Association for Nuclear Decommissioning Study: “On a scale of zero to 10, I’d say the decommissioning process has advanced by about 0.1 [...] I think the prime minister was right in saying that things are under control now [but] predicting what the situation will be in 2020 is still very difficult.” [...] “[Melted nuclear fuel] could be mixed with other metal, it could be as hard as iron or as breakable as a concrete block [...] There is no way to know such factors and, without them, removal isn’t a possibility.” Ishikawa believes that designing a specialized robot to locate the melted fuel is probably going to be required. If that doesn’t work, easing the upper limit of radiation exposure for decontamination workers at the Fukushima No. 1 power plant is going to be essential [...]

    for real ?
    you mean there is no technology in existence that can pinpoint the location undersground ? this does not pass the smell test.

    how about they start by looking for hotspots emitting high rad readings. thats a good clue.

    am I missing something ?

    If he is right and it has taken tepco two and a half years to decommission 0.01 percent of the accident, I don't know what we are worried about, that means at that rate in 2250 years of continues leaks into the environment, they will have solved the problems associated with decommissioning, sounds about right to me.
    Only problem I see, will there be anybody left to clean up after 100 years?
    If you want to know we're corium is, send in the A team from tepco, that is all the members of the board of directors of tepco and Abe can be the supreme leader, follow me boys, be happy and keep smiling and you will be fully protected, as per minister of propaganda?

      I remember they stuck an endoscope inside a reactor a year or so ago but it didn't reveal very much. Too much steam to see anything clearly. Finding, extracting the melted fuel maybe too difficult as even robots might not be effective. To protect the electronics of the robot so much shielding maybe necessary the robot will be to big and heavy to manoeuver to where the melted fuel is or, if the fuel is still inside the containment vessels breaching them to get at it would so contaminate the site it would be better to just leave it there and entomb the entire structure if they can solve the ground water problem.

        Of course its a fair bet either through rising sea levels ( leave global warming out of the discussion because we are talking thousands of years here or longer than the Great Lakes have been around in their present state) and coastal erosion the whole site will end up in the Pacific one way of the other but it at least it will be contained for all those alive today.

    • Meltdown of a GE BWR of these designs (Mark I & II, slightly different primary containments [drywells] has been gamed more than once. Oak Ridge melted a mockup on purpose some years ago, and TEPCO even had an animated feature used in training describing the course of events well before 2011.

      It takes 16 hours from loss of feedwater with no restoration (complete LOCA) for the reactor core to melt all the way down and start going through the sizable holes in the bottom of the vessel to collect on the drywell floor. Where it goes from there is uncertain, but concrete isn't that difficult to melt. Unit-2's corium (or a hefty part of it) went down the vent conduit(s) to the torus and hit water during that first week. Units 1 and 3 took longer if they went straight down into the basement instead of into the torus, but if they're in the basement (which is actually in the first basement level), they're in water.

      • JoyB, no doubt they must have some idea, some educated guess as to where the coriums are. I don't believe they have no equipment that could help them find a heat or radiation signature. Not that I'm well versed in the technology required just a personal hunch. They are somewhere in the ground below the plant not boring a hole to the earths crust. I read somewhere that the ground itself would act as a heat sink. Also read elsewhere as you suggested melted corium would pick up melted concrete and steel it melted through diluting the mess.
        Sadly although not a dramatic explosion or china syndrome groundwater is carrying massive radiation to the ocean. Even Gunderson says they don't want to fix the problem. They are not asking for international help. Japan wont spend the trillions required to fix or remediate as best they can as it would bankrupt the country. Its sad.

        When you say they're in water. You mean the top part of the blob would have been exposed to water until the water boiled off, or a thick enough crust of salt formed to insulate the blob from the cooling effects of the water.

        We know they had to use sea water on them. Enough heat energy will cause the salt to decompose and form the outer crust. The inner crust would be the concrete, boron, zirconium, misc. metal, etc.

        As the energy increases, the poor old basement floor gets tore a new one. Blobs on the floor are just not in the proper geometric configuration for today's MOX fuel.

  • The above article is a classic example of spin or as this unrefined politically incorrect Canadian prefers to call it "Bullshit". Perhaps propaganda is a more technical term. The picture of the Olympic logo crap behind PM Obe's ugly face and the question headline "Fukushima 2020: Will Japan be able to keep the nuclear situation under control?" What a way to frame a corporate agenda. They even as you may notice report in "fiscal" years which is March to March. Talk about a corporate agenda.

    “I think the prime minister was right in saying that things are under control now,” Ishikawa said, but “predicting what the situation will be in 2020 is still very difficult.” That part is true. We can only hope enough people wake up. Who knows? Perhaps some deserving corporate types will receive a bullet through their liver. One can always hope.

    Yeah if your talking about the spin, the bullshit, managing the situation, however which way you want to frame it, if newspapers can get away printing this drivel things are well under control.

  • And I can smell the bullshit right across the irradiated Pacific ocean. Don't know where the corium is. Come on. Don't want to say sounds more like it. Don't know what to do? They know what to do but they looked at the price tag and said "Fuck it, we'll just pour water on it and hope for the best". No way they will put out the 20 trillion needed, why that would bankrupt Japan and spiral their precious world economy (that most folk are brainwashed into thinking they need) into a huge recession. We need clean water, clean air and a clean food supply not more money. Obummer and the other world bleeders are suspiciously silent on Fuku Die-ichy dont you think?

    I think it is pretty clear that the coriums are in vertical line down from each reactors, just not sure how many meters..

    How about this method, look at this monster drill:

    http://www.jotocorp.com/images/tbm.jpg

    They have these day those monster drills ,and some are actually robots if i understand right, so how about getting that kind of drill or maybe some smaller robot drill to few kilometers from the plant ,then start drilling the tunnel that would be in same line with the all reactors 50-100 meters down from ground.If they could measure the precise location horisontally of the coriums they could drill the tunnel like 10 meters down from them ??

    Dont know is the tunnel robots that could drill vertical , so how to get the final meters to reach the coriums ??

    But if the tunel would be there, they could fist make it stronger with pillars etc….then set up a freezing system down there with cooler equipment, if that would succeed it would give time for the issue what to do and keep keep the coriums cooled…

    They do drill those tunnels in very hard conditions like under the seas so i would like to think it is possible…

    • Corium, like any other liquid, will tend to follow the path of least resistance. For unit-1, that is likely straight down through the drywell pad into the basement levels. For unit-2, it apparently went through an open vent conduit to the torus. For unit-3, what didn't get blown out is 'somewhere else'. If any of the flows made it out of the basements it's probably following the groundwater toward the ocean (path of least resistance). If it's still viscous enough to be moving, and if it's in water that isn't likely.

      They need to divert the groundwater 'river' away by installing a cofferdam uphill of the reservation. Once that is done, some kind of concrete/resin mixture could be injected into the corium 'lava' tubes to immobilize and further insulate the masses. Leave them in the ground or basements, there's no need to dig it out if it isn't in water flowing to the sea.

      " is covering the coria (corium is a latinism, so coria seems to me as the correct plural)"
      In latin language ending "a" is mainly female.
      Plural of a word ending with "-um" is always "i".
      So plural of corium is corii.

      After gathering many details about melted core research, for me it seems pretty possible, corii sink/melt down straight vertically.
      They do not stop fissioning and nothing can cause their temperature to sink as they don't mix with anything on their way down. Corii are untouchable as everything is vapor before contact at those incredible high temperatures of about 5500°C.
      They will meet magma in about 7 years. The tubes corii melted down
      are glassified and are a perfect way for magma and corrii coming
      back to surface then.
      Tepco and Abe seem to rely on that imho.

          at what temperature does hydrogen separate from oxygen ?

          perhaps this explains the burners visable on the cams

          notice there are more burners. that means more hydrogen

          the corium is in the water and they know it. everyone else just need to connect the dots.

          this explains the very high radiation levels, steam and need to burn off the H

          just my 2 cents

    But just you try to sell beer on the beach or in your basement and see how long that free enterprise will last.
    The choice is to spend trillions or allow the ocean to be radiated.
    We have Japan Times giving voice to Michio Ishikawa who's the type to say "An environment with strong radiation is a nuisance for the general public". No doubt they have no intention of fixing this.

      Tepco gets to keep destroyed reactors on the books as assets. WTF?
      The idea of a "good" and "bad", or solvent and insolvent Tepco is growing.
      As I pointed out once, Fuku is only about 20% of Tepco's total electrical output. So there are assets.
      No one should expect anything but the most minimal compensation they can get away with.
      I really think the decontamination work will be "scaled back" after a time, but the Fuku ghost towns will remain just that.
      It's the rest of the contaminated areas that will be "gamed".

          • Physics of reality does not have these corium lavas still hot enough to actively melt what they are in contact with. Thus they are in the basements or just below. May still be technically molten – like the largest flow at Chernobyl, that made it through the piping to the lowest level and then 3 meters into the granite bedrock before cooling enough to stop – but it's not on the move.

            The issue is that the groundwater is picking up gross contamination from the surface of the coriums and taking it to the ocean. Both inside the lagoon and beyond the seawall. This needs to be stopped, but it's unlikely TEPCO/Japan have any plans to do so.

              • Sorry, soern. Reactor cores (or fuel assemblies in spent fuel pools) don't fission into molten lava when there's no water. They melt down via decay heat.

                Yes, uranium and plutonium fuel isotopes decay by fission a certain percentage of events, but that is not a chain reaction either controlled or explosive (like a bomb). It is spontaneous, just like the myriad of other decay events that caused the fuel to melt and serve to keep it molten. A corium mass that encounters water will have 'flash' fission reactions on the presented surface, but it lasts mere fractions of a second and involves only the fissile fuel isotopes that are at that moment on the surface of the mass and in contact with the water. 5% or less of the uranium and plutonium isotopes in the entire tonnage of reactor fuel are fissile.

                You can find this information for yourself if you don't believe me as some anonymous pseud on the internet. I'd encourage you to do just that. The laws of physics are not suspended or abrogated on human command, no matter what anyone wishes them to be.

    Rainwater Flows over Tank Barriers at Fukushima Plant
    Tokyo, Oct. 20 (Jiji Press)–
    Tokyo Electric said Sunday rainwater flowed over the barriers around storage tanks containing radioactive water in a total of 11 tank areas of Fukushima plant the same day.
    Simultaneous overflows had not previously taken place at so many tank areas at Fukushima plant.
    In the past, at least eight of the 11 tank areas, radioactive materials in excess of the provisional limits set by Tokyo Electric have been detected in water inside the tank-surrounding barriers.

    Many methods have been developed to massively accelerate the conversion or transmutation of radioactive materials to more atomically stable elements. I read over the suggestions here and not one I have seen suggests the most obvious and only possible solution. It appears that real and fundamental permanent solutions have been deliberately suppressed. When they have been presented they are not only denied but in many cases violently denied. A big reason appears to be is that The Powers That Be in the whole field do not want their mega-billion $ troth to end. The other is that it flies in the face of standard junk science thrown in the faces of the public. "Nuclear decay is only stochastic or probabilistic, never deterministic." Different versions of conventional transmutation are known and discussed in the literature: by photons, by neutrons, by charged particles and by scalar fields. Of many solutions, to start: "Brown's Gas" — Proven to reduce nuclear radiation up to 96% within minutes : http://pacenet.homestead.com/Nucwaste.html – Planetary Association for Clean Energy – Commercial availability of the technology here now.

    I would suggest that some contributors here start a new thread or forum site where these solutions can be strategically and powerfully introduced into the mix. If this can be demonstrated at Fukushima then they can be demonstrated wherever nuclear byproducts exist. Those who complain there is nothing to be done, here is a practical approach.

As far as Obummer being black that is of little consequence to me. But just because he's black doesn't mean he's any better or different then all the other ugly white men who have mislead us. I prefer to make my point of view known in other ways besides capitalizing whole words. Everyone is entitled to express themselves how they see fit.

      The link you gave looks very interesting. But there are a lot of technical words to get through. It seems to be based in a process of "transmutation" — like maybe you bombard a dangerous radionuclide with neutrons or protons and it changes it into a less deadly element?

      Something like that was apparently developed by a Dr. Radha Roy a few decades back. Can't google any patents, but maybe his ideas were just stolen?

      If you could break this down into "clear English," that would be much appreciated! Maybe there are methods that could at least be successfully applied to existing nuclear waste. That would be a service. Though as for the stuff already massively being let loose…..?

      Then all the NPP's need to just be SHUT DOWN.

    At the bottom on page 3 of this TEPCO .pdf dated July 2012, the plan is to remove the lids and place a special melted fuel removing machine over the reactors. To do that, the 'leaks' have to be sealed so the containments can be filled with water, before the lids come off, to shield during radioactive debris removal. Right now the containments can't hold water.

        The 'plan' also calls for a special container to place the melted pieces in underwater for removal. If it was made to hold a 100lbs, with about 100 tons of melt needed to be removed from one blown reactor then they only need 2,000 containers, X3 melted reactors. Where do you store 6,000 containers of highly radioactive debris? Hanford?

    • Filling the containments with water was considered early on in the disaster. It was determined that even if they were holding pressure (and none of them are), the water would make them far too unstable on shaky ground. Besides, the coriums are not likely to still be in the drywells – they'd have melted through many months ago (during 2011).

      They had been injecting nitrogen to prevent more hydrogen explosions back out of the blow holes, but stopped that a couple of weeks ago. They're in water, hydrogen from radiolysis is no longer dangerously significant.

      This "corium removal machine" thing is hilarious. Moreover, it doesn't exist. And if it could be made to exist, the corium isn't in those reactors or in those drywells. There is no point trying to dig it out, it's well shielded by the earth if they can stop the groundwater from washing contamination out to sea.

    So the President of the decommissioning study acknowledges that virtually nothing has been done, and that they haven't a clue there the melted-through fuel even IS, and yet "the prime minister is right for saying that things are under control"?

    And how many people have to drop dead right in front of THIS man's face to revise that?? These people want to "save face"? Let them paint the faces of ghouls with skull and crossbones all over their own sorry faces and parade in the public square. It's the only "face" they have left.

    • WNTF, As I pointed out above, Michio Ishikawa is also chief advisor and past President and CEO of Janti, a pro nuclear group. So what do you expect? And PM Abe is right in saying things are under control as no large money is being spent to fix bleeding radiation into the sea, Olympic bid won, Japanese people still fixated on the economy, happy with "Abenomics" even though nothing much has trickled down, Fukuvictims still not paid fairly, public buying into decontamination efforts and no international pressure to do anything and finally besides the few who read this site, the general population of the world is unaware that their health is being compromised to turn a profit so yeah, from a pro business, pro nuclear point of view things are very much under control. Name calling won't help.

    All the books of all librarys of the world full of wisdoms and philosophy…..and we end up in this situation…wtf ??

    Where are the philosphers and teachers leading the decision makers of our time to make the right decisions, i am sure that in ancient Greek, the leaders did listen also the wise man….now in our time the leaders operate solo without any wise man counceling them….

    So ,we have a world that operate only by the prinsible of elected fools, and when the voters are in the dark they can vote what ever idiot to the job that think they can make them more rich….

    This is also a system crysis….the system dont work ,democracy as it seem to is ,wont work….we need a system that secure the situation by getting leaders that are capable for the job, and especially for hard time like now with Fukushima.

    This model of how it is now,is fucking dead! we need intelligent people to be the leaders, and not just people who think only the benefit of corporations…

    Noy saying we should turn to communist, what i am saying is we need a system that secure the the proses where we can get real leaders for he jobs to secucure the world…and thats`a us…

    • Timex, I once had a Professor of Philosophy within my circle of friends and I asked him once to tell me what practicle use philosophy could have. His answer? It gives me a job. None of the world leaders have ever had anything besides power on their minds. Englands old growth forest was cut down centuries ago. North Americas is almost gone and the South American jungle is being burned up as we speak. The Thames was rotten with sewage before the industrial revolution and on and on. Mankind hasn't changed much at all. Is a no brainer to not spend trillions of dollars to fix fukushima for those with the money. Rome fell and so will this present nuclear fuelled economy and mankind will crawl back into the wilderness a bit more mutated and not any wiser.

      "democracy as it seem to is ,wont work"
      well, democracy never worked properly.
      The old Greek's society, which claimed to have invented democracy, were based on slavery.
      Todays democraties have not much to do with ancient direct forms
      of democracy, as today PR is more important than wisdom.
      Further worldwide we have a human population which avoids thinking, reading, education… totally to 99%. So what?
      Nothing to expect at all.
      Todays very most important thing is to go shopping in order to impress the neighbour. Or worse.
      Somewhere above – no it was a comment in that racing boatmans article i read today: God must be pissed off by mankind especially now and since day one. Agreed totally, ME TOO!

      • Well if you read your history. That is if you can believe as many scholars do that the Book of Genesis is a historical narrative handed down through word of mouth long before writing and paper and Christianity. Every religion and civilization has a flood story. The Genesis version, denotes God in the plural, therefore we might well be talking about space aliens and a bar bet. The ancient Greeks thought there were many Gods and earth and humans were made by the Gods to entertain the Gods. God already attempted to destroy us as he already got pissed at us if you remember the story. Nevertheless since God expressed remorse for causing the flood and promised not to do it again I guess he/she/they will just have to let us do it to ourselves. Serves them right for creating us in Their image I guess.

    The drone shuttle, and its "secret" mission told us where the corium is. If that craft indeed does have deep radar sounding tech, that can find deep Uranium deposits like the big one under Milton Vermont, and can locate deep underground oil deposits, the corium location must be easy for that beasty…

    Mark, Wikipedia in the article on Browns Gas made one short opinion comment referencing to an article with a short comment from someone who really did not understand…One positive experiment of many: 1991, China's Baotou Nuclear Institute released a Report #202 , "The Results of Experiments to Dispose of Radiation Materials by Brown's Gas", which establishes that experimentation on Cobalt 60 radiation source decreased radiation by about 50% or half-life of radiation — but sometimes more radiation is decreased which needs investigation of possibilities for decreasing more of the radiation in single treatments of exposure to Brown's Gas flame, lasting only a few minutes, in the samples as described in the table below.

    First Experiment Second Experiment
    Source Intensity 580 millirads/hour 115 – 120 millirads/hour
    After Treatment 220 – 240 millirads/hour 42 millirads/hour

    "In another test conducted by Yull Brown before a public audience including U.S. Congressman Hon. Berkeley Bedell with a committee responsible in this area of concern, the experiment ran as follows as reported by the press: "Using a slice of radioactive Americium … Brown melted it together on a brick with small chunks of steel and Aluminum … After a couple of minutes under the flame, the molten metals sent up an instant flash in what Brown says is the reaction that destroys the radioactivity. 99% readioactive…

    • blessings2all, first you should have replied in the original string above as to not disrupt the conversation which should be around the news article posted by Administration. But obviously you are new here so please take this as a friendly heads up to general practices.

      Secondly I am no rocket scientist but a process that basically uses electricity to split the hydrogen and oxygen contained in water to create a flammable gas, that gas, Browns gas is not going to neutralize the huge radiation that the melted cores are producing. We are talking tens and hundreds of Seiverts worth of radiation which off the top of my head is like billions of atoms disintegrating every second and any man would be dead who walked there and any robot would be rendered useless. Also I remember vaguely over a year ago (two?) someone mentioning Browns gas and it was determined here on enenews that it wouldnt work. Worth a try? Maybe. But there are other things they could do and one thing would be to divert the groundwater high up the mountain somewhere to limit radiated water bleeding into the ocean. A no brainer as I thought about it before I read that Arnie Gunderson, former nuclear power plant operator among other credentials suggested it. But that in of itself would be more money then what they want to spend. So even if your Browns gas was the saving grace they wont do it as they won't spend any money on this as it is a multi-trillion US$ project.

    Fukushima Decommission Plan:
    1. Locate Missing Melted Fuel: It is of vital importance to map the corium lava tubes, and to confirm the whereabouts of the missing 218 tons of nuclear fuel, don't you think? Use modern drilling techniques to locate and follow Corium Lava Tubes1,2,&3 down to the missing corium. Accomplish this task in 2014.
    2. Stop Groundwater Contamination: An Extended Impermeable Wall and/or the Frozen Wall needs to be built to isolate the Fukushima Ruins, surrounding all four reactor buildings with underground walls to stop the flow of groundwater through the Ruins. Accomplish this task by the end of 2014.
    3. End Ocean Contamination: The mouth of the harbor must be sealed with a permanent gate. Accomplish this task in 2014.
    4. End Atmospheric Contamination: Locate melted fuel in the reactor ruins, neutralized with boron and grout to stop the smoke and steam rising from the ruins and from the ground around the plant. Accomplish this task by the end of 2019.
    5. Store Spent Fuel: Put the fuel from SFPs1,2,3,&4, and the Common SFP into permanent dry cask storage. Accomplish this task by 2016, after all fuel at the plant has cooled by at least 5 years, and is ready to go ino Dry Cask Storage.
    6. Fill Reactor Buildings1,2,3&4 with grout. Accomplish this task by the end of 2020.
    7. Treat and Dump Stored Water: All remaining contaminated water stored at the plant should be treated and dumped by the end of 2019.

      TEP.gov must abandon the fiction that Corium1-3 are contained in the Containment Vessels. My guess is that not even one of the three corium blobs, when they are located, will be found to be inside Reactor Buildings1-3.

      The ultra-high rads from groundwater at the site indicate that one or more corium is located underground.

      The wispy steam and still water seen in endoscopic videos of Containment2, along with the low level of water, is proof enough that corium is no longer present.

      The international community must insist that Japan locate Corium1-3, and formulate a plan to recover it.
      The international community must insist that Japan build an Extended Impermeable Wall around Reactor1-4, to stop groundwater from coming into contact with melted nuclear fuel in the ground underneath the three melted reactors.

      Where is the damn corium, eh, Abe?

  • Actually, his feelings are telling him the truth, while his head and ego are telling him to keep going with the 'lie'.

    The journey to the heart and opening it, is a sacred and mysterious one. Not everyone makes that journey during a whole lifetime.

    Keeping the heart closed down and in darkness is what allows the nuclear industry, GMO's, DU, and all of the other death and suffering in the world.
