AFP, September 10, 2013: [...] TEPCO’s own estimates suggest the full decommissioning of the site could take up to four decades and that much of the trickier work is yet to be done — notably the removal of reactor cores that have probably melted beyond recognition. According to the utility’s own plan, these reactor cores — which are feared to have seeped into the containment vessels and possibly even eaten through thick concrete — will be removed around summer 2020, just as thousands of athletes descend on Tokyo. [...] In an editorial published Tuesday, the left-leaning Asahi Shimbun said the fact of Shinzo Abe’s having stood on an international stage and promised to resolve the Fukushima crisis was a welcome move. “This is an official pledge made to the world,” it said. “Abe must take action so that he won’t be seen at home and abroad to have just stretched the truth to bring the Olympic Games to Tokyo. His ability to address this issue is now being watched.”

Japan Times, Sept. 9, 2013: [...] the world will be closely watching how Japan confronts the catastrophe at the Fukushima No. 1 nuclear plant, where three melted reactor cores and dangerous spent-fuel pools continue to pose a menace and highly radioactive water is accumulating daily, with some 300 tons of it flowing into the Pacific each day.

    Fukushima for first graders. Why not put out a coloring book while you're at it. Dumbfounding.

      FEARS cores have 'eaten thru'??

      At 2400-2800c corium burns through concrete at the rate of 5cm per hour, and the base of the concrete dry well beneath the pressure vessel is about 8m as far as I can discover (anyone with better knowledge?). The time it would have taken the corium to burn through that thickness is about 160 hours. There are 24 hours in a day so 160 hours is 6.6666 days. There's one for the numerologists amongst us! Debbil's work for sure..

      So let's say that after the fuel to start melting following the main cooling system failure during the earthquake (not tsunami, earthquake that fractured the cooling pipes), within about a week the corium would have been into the ground. Providing of course the thermal power of the corium was not exhausted by the concrete as is passed through.

      Also, Arnie Gundersen puts the temperature of corium closer to 3500C, so could go through even faster, and who knows how fast or far it may have gone through the rubble that FukuSteamer was built on…plus, how many fractures or cracks in the foundations now from hundreds of tremors since…does the rise of the tide now contact the coriums and create all the steam that is rising from the ground and between the reactors now?

        I assume that a fully blobbed blobbium, that had taken the path of least resistance thru the 'control rod' holes in the bottom of the PCV, taking out the control rods (hence the 'cold shut-down 'conditions') and exiting the control rod drive cavity, quite probably enlarging the holes as it flowed. See: http://en.wikipedia.org/wiki/File:Reaktor.svg

        If the blobium stayed blobby and didn't form random elephant foot stylee sculptures as it took the first steps on it's journey to the centre of the earth (remember glasshopper, it's the journey not the destination – unless you're late for the loo!), it COULD by now have:
        5cm per hour x24 = 1.2 meters per day
x 910 days = 1092 meters = 1.092 kilometers (ish)

        Buts that calculation was for concrete, not conglomerate sand/mudstone that has been washed through by, oh, about 1000 tonnes (1000 cubic meters) of ground water and cooling water per day for 910 days….
        So who really knows…

  • We Not They Finally

    Step One: See if they can successfully remove a single fuel rod from SFP4 in November without an arm of the remote crane breaking apart.

    And shame on Asahi Shimbun. It was GOOD that Abe pathologically lied to the whole world to get Japan the Olympics? That NOW they can see "whether or not" he "stretched the truth"?

    It was GOOD that now three times as much money will go to building a stadium than to the entire ongoing effort at Fukushima?

    That's all GOOD?

    Abe did not even "promise to resolve" ANYTHING. He said it was already under control!!

    I know that they are tired and they must be worried. But you reach the point where you are seriously cracked in your own heads to go along with ANY of this.

    Oh, but they are just saying this because they care about Japan? No, they DON'T care about Japan. They don't even seem to care about their own poisoned childhood population. Japan will go down in history (if there ARE any records left) as the worst pack of criminal monsters the world has ever seen. And if the journals there and the university professors cannot get past their own timidity to confront that, then they will just go down as collaborators and complicit in the crimes.

    Sorry folks, your country is rotten to the core. But you still have NO RIGHT to lure athletes there to their deaths.

      Millions of Japanese are completely innocent and have/had nothing to do with any of this mess. The government is corrupt, along with the trans-national corporations. You can't blame the people for being nearly helpless to fight against such powers, especially when many of them were literally born into this world and take it to be the norm.

      Millions of Japanese ARE fighting against this insanity. It just goes to show that an even larger effort is needed.

      When this happens in the U.S. (or any other country), you will see that the exact same "procedures" will be implimented.

    Fuel debris removal BEGINNING in 2020 is based on several best-case scenarios. The info's there @Tepco & METI but it's way too early to make any assumptions.

    So, is the plan to coordinate the removal of the last bits of the melted reactor cores and spent fuel rods with the opening ceremony and the lighting of the olympic torch? Heartwarming indeed!

  • Well again, some of the atom. .. It seems to me that Joseph Rotblat was the inventor of the atomic bomb and the first I became aware of the horrific possibilities. Because even as a foreigner was attached to the project Manchatan, after arranging the required formalities .. The truth value of this claim due to the following publications and videos:

    The bigger question not being asked is this: Can we safely decommission existing plants in operating condition? Some agency should be working to construct and model an effective way of removal of spent fuel from some existing overcrowded spent fuel pool, transporting it to long term storage sites, and seeing what is involved in isolating and cleaning the damage left behind. Until they can effective accomplish this (government regulations etc.) on one of the plants operating beyond it's life expectancy, they will not be able to attempt to attack this out of control situation. Every nuclear plant is another accident waiting to happen – and the solution is to keep increasing the risk, expecting that some future generation will have the will/the resources/and the technology to clean up this mess.

    Japan came very close to evacuating Tokyo, and some experts say that it should still be evacuated, because it was hit hard by radiation right after #3 exploded and released a massive amount of radiation.

  • How can the cores 'eat' through concrete when the whole place is in cold shutdown, according to the 'experts'?


    Report comment

    • omniversling

      Shutdown CONDITION was the official statement doc, be specific…ie control rods inserted between fuel rods, and minimal fission in containment vessel (appendix: control rods inserted between fuel rods as melt factor, and minimal fission in the slag debris remaining after the blobium left the building).

      Yes, the temperature guages, as they failed one after another, showed the temperature on a descending trend…like the blobiums themselves…

    We need a worldwide consortium made up of experts in the field to start brainstorming solutions to what is happening in Fukushima and what can be done to FIX it. We need them NOW. Each country will also need to commit funds to this effort, since it is and will continue to affect the entire planet. The consequences could be the extinction of all life on earth. It is past time to do this. Japan is calling for help and they can not handle it alone.
