Nuclear Engineer: Almost all nuclear engineers have known since early on that the reactors have melted through the core

Published: May 18th, 2011 at 6:24 pm ET


Interview with Akira Tokuhiro, Nuclear Engineer: Fukushima and the Mass Media, Vivian Norris for Hufffington Post, May 17, 2011:

[…] Professor [/Nuclear Engineer Akira Tokuhiro] teaches in Idaho and as an academic he is still free to tell what he believes and believes almost all nuclear engineers following this disaster know, and have known since almost the beginning, that the reactors have melted through the core and that this has not been admitted until just these past few days when access to the computer data from the control rooms was obtained […]

    These kind of articles makes us angry. Anybody want to start an online petition to some senators? How do we do that?

    • Mudge

      I called Senator Dick Durbin’s office and was referred to the EPA
      I called the EPA and was referred to the NEC
      I called the NEC and they require emails only
      I emailed the NEC and they have not responded yet

      I don’t think anyone cares

        These are the same people in offices that invent wars and send your children off to die in for their greed, as in the GOM and other events you will see the same over and over again, they hide behind lies and lawyers advising them, it’s not about you, it’s about them and their plans, they know more then you always and for reasons not disclosed to you. You are the ant they don’t see or care about, now shut up and pay their salaries !

      • Here’s my take down here. One of my senators finally sent a response to my emails going back 3 or more weeks. He suggested I go to the NEI website (Nuclear Energy Institute) the lobbying and PAC funder of politicians for current poop on the Fuku debacle. Not that they would do any massaging, editing or just plain lying in their reporting to protect their footprint in the USA!! Scratch another US Senator for any support in getting straight info. Haven’t had any response from any of the MSM major players yet.

    • Cassie

      I have come to the conclusion, that if by some miracle, this is not a major hit, it is only a matter of time. We are being poisoned via air, food, water. And they took our jobs, houses, pensions. We never had reasonable healthcare.

      The lesson is that blatant and rampant sociopaths in total charge of a planet simply does not bode well for the long term survival of a species.

      • Ashen

        I agree Cassie. It was inevitable.

        Pretty much sums it up. We have work to do.

      • ZombiePlanet

        If you dig deep and study the elitist long term agenda you will find that they want a massive reduction in human population to where there are only 500 million alive.

        At this point they will control these people with their armies, drugs, genetic engineering, etc. to create a massive slave class to keep their (elitist) technologies up and running.

        This will allow them to use this planet any way they want. Everything will be at their finger tips.

        These people believe themselves to be in the long bloodline of the ancient, so termed, gods. It’s ancient Egypt all over again.

        They hate all of us.

        Ecc 1:9 ΒΆ The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun.

        Sorry folks, that’s just the way it is.

        • Ashen

          I’m with you 100% ZombiePlanet. In your opinion what would happen if someone in the elite’s OWN ancient bloodline chose to take a stand against them? Ecclesiastes 3 – there’s a “time” for everything. I believe the time may be now. Any thoughts?

          • ZombiePlanet

            Such an individual would require divine guidance and protection. Such a person will only arrive from the other side of the fence.

        • You really need to see the BBC Horizon documentary “How Many People Can Live On Planet Earth?” with Sir David Attenborough. It is fascinating, utterly logical, and comes to the depressing conclusion that with the resources we have left 500 million is the maximum sustainable.

          David Attenborough, who has devoted his life to studying animals and our environment, virtually ends up in tears when he comes to that conclusion.

          2 unacceptable solutions are war and genocide. I say unacceptable because those remaining would want revenge against the perpetrators. Does it not make sense then to achieve this target via a series of natural catastrophes so that pointing the finger of blame becomes a very difficult task?

          Like everyone, I’m not happy about any of this, nor the way things are going at present but, we have all contributed to the problem so like it or not, none of us has the right to a clear conscience.

  • the sin of omission. we will obviously just have to find out the what damage has been done the hard way.

    Though The POTENTIAL. Is Nuclear.

    • Ashen

      What are we all facing if 4 – 6 reactors meltdown, explode, or whatever? What is the truth and severity of the situation? I want to know. If we all die and nothing can stop it – at least I want to know why. I want to be able to stare “death” in the face rather than kneel down before it. I don’t want to be uninformed.

      • ashen
        Stay informed.
        Educate yourself.

        Watch the movie the road. In all reality this is an event that will unfold.


        In the mean time, find comfort in being prepared as best you can. (be prepared mentally as well). You are already ahead of the curve for paying attention and asking questions…
        Keep calm and remain focused so that, in the event “You do” find yourself living in a post apocalyptic nuclear situation. You have tools and training for survival.

        Learn about the common known types of nuclear radiation such as beta gamma and alpha. Learn how they effect you internally and externally.

        Learn how to protect and shield yourself from it. Mass will stop any radiation. Though the amount of mass in “quantity” must be able to provide enough protection to support a contamination free environment.

        The denser the mass the better. Think lead, Metal, concrete ect. 6ft should be sufficient to stop gamma radiation.

        Download a copy of the following to a laptop charge the battery and keep it in your emergency kit at all times:
        google earth.
        a survival guide.
        A fallout guide.
        A text document from wikipedia Labeling:
        Types of radiation; radiation exposure charts;
        And a radiation converting chart; This way in an emergency you have written material’s and guides, on hand. to help you survive.

        Also it would be helpful to even create a radiation jump suit. so that you can move around freely if you find your self in a dangerous situation.

        Nuclear fallout guide’s are a great place to start btw… I suggest You start your adventure by reading this article… It’s a few pages of everything you really need to know…( print a backup of this one…)
        Call this the new bible:

        The situation; May I remind you; could get very ugly. I assume without a doubt it will. There is no shame in being aware…

        stay alert, and don’t waste time. If you want to be prepared. Do so intelligently. Many of my friends have told me I shouldn’t worry about this situation. They are certainly misinformed.

        I will admit no shame in treating it with the respect it deserves. It truly is thus far the biggest tragedy to ever occur on the planet, in humanities wake.

        I will also remind you:
        TEPCO. <—- Does not have a plan.

        If your toilet was over flowing for hours, and you did not fix it. the situation still gets worse. It rots the floor, then it molds; rots your support beams ect.

        and if you dropped a duece, and everyone would literally faint if they went in to fix it???

        well thats the point, there…

        If you don't fix it, I just demonstrated how the situation will continue to slowly and slowly get worse…

        so here is my point.

        Fukushima is the toilet.
        People are not fainting from the smell. they are dieing. The floor and so on are the walls in which the nuclear fuel will slowly conquer and overcome. Until you lose your house.

        Tepco has demonstrated that there is no sufficient way to end that said "chain reaction"…

        Thus your toilet just totaled your house.

        So its really up to you, on how you "feel" you should be "reacting" right now… before your sitting at home reading and are forced to deal with the !$h!t!.

    Anybody got any informative links in Japanese like that one forum you guys were talking about. ? Thx

  • 1111

    .. a telling statement – hope it is a translation error and not a reflection of the “wisdom” of almost “all” nuclear engineers. Perhaps a re-engineering of this puzzling statement “reactors have melted through the core” ?? is in order. The “reactor does not melt through the core” ??, without cooling circulation, the core bundle fuel overheats, melts, contacts the bottom of the containment vessel and melts through to the outside of the vessel. No sense trying to sugar coat it guys, everyone on the planet knows that that stuff gets REAL HOT – REAL FAST in event of circulation failure. The nuclear science / engineering community needs a credibility boost – suggestion as to how to achieve same – how about some genuine facts – especially – what is the status and near term event forecast for melted fuel external to all containment in reactors 1,2,3,4 and what is the forecast for stored spent fuel that remains in SFP / has not been blow off site ??

    • Rami

      Temperatures of reactors here, 3 has dropped since last week. If this is correct.

      • J1

        Temperature has dropped because the molten fuel is no longer in the pressure vessel but probably seeping through the ground as we speak!

        • 1111

          Finally – accurate information – you must be with the nrc or some other highly vaulted organization that always has the well being of the public in the forefront off all that is said and done by such agencies.

        • mikael

          I think its a technical issue, if the vessel is emty, it reads no heat.
          But reactor 1 showed us that it can rest in a pool under the wessel, and by time, sipp thru the castings, and into what ordinary walls and flooring.
          They are just telling us something, not nessesery meaningfull, but something.

          I dont belive in any Entety or whatever coming down to rescue us, sorry, but this is our mess, and the responsebility rests solely on our own shoulders. It was a an acsident, shitt happens, and the real danger is the afterplay and the blamegame, it all diverts the antetion from the bigg shitt, the meldtdowns that are happening.
          Who is to blame and charge, is matter of its own. But as stated earlyer, the downplaying and lies must end. Its gone beyound Tjernobyl, and the lesson is to know that to do, and if so, by Books, not CDs. Obvous resons.
          Its everyones duty to inform oneselfs and prepare for the woursth case senario.
          It may happen.
          We realy dont know.

      • mark V

        Of course we trust the TEPCO information from day one, but just, just, because this is such unprecedented event, let’s make sure that the Japanese government is saying the same. Appears they indeed are. Hasn’t “core on the floor” become a hit yet?

    We’re just going through the “motions”, another cycle, etc. There is nothing new under the sun. What is now has already been. The fact is: We’ve all been here before although most don’t remember. Just as the Oracle told Neo in “The Matrix 2”: “You’re not here to make choices, you’ve already made them. You’re here now to understand WHY you made them.” Read Ecclesiastes Chapter 1 in the bible and see if it strikes a chord with you. It talks about everything being “Vanity” and cycles of time. What if we are already dead and this is just a memory? A reliving of WHY we made the choices we made? I’m not attempting to persuade anyone to any belief. For those who have a problem with what I say – get over it. If I’m not being truthful what is there to be upset about? A lie will aways surface sooner or later. “Truth need not scream.”

    • J1

      cycles…yes indeed.

      Interesting how many do not take notice of the many cycles that which the world runs on.

      Electricity = 60hz
      Your car engine = RPM
      Your heartbeat = PPM / Heart Rates
      the weather = 4 seasons
      Music = 4/4 time
      Calendar year = 12 month cycle
      1 day = 24 hour cycle
      fashion trends = too many to list

      Then there’s the larger cycles that appear every 75-100+ years.

      World Wars
      Civil Wars
      Financial Markets
      Volcanic Eruptions
      Fourth Turnings –

      Then there’s the Super Cycle. The mother of all cycles which peoples of centuries past have tried to warn us.

      Time to get right and see the bigger picture.

    Radiation tests lacking / Nuclear plant workers unsure of internal exposure levels
    The Yomiuri Shimbun

    Nearly two months after the start of the crisis at the Fukushima No. 1 nuclear power plant, only 10 percent of workers there had been tested for internal radiation exposure caused by inhalation or ingestion of radioactive substances, due to a shortage of testing equipment available for them.

    Tokyo Electric Power Co., operator of the crippled nuclear compound, is finding it impossible to use testing apparatus set up inside the facility because of high radiation levels recorded near the equipment.

    A number of personnel working to overcome the nuclear crisis at the facility are increasingly alarmed by their lack of internal exposure testing. Some have said they may have to continue to work at the facility without knowing whether their radiation exposure levels have exceeded the upper limit set by the government.

    On Tuesday, the government revealed a timetable for ending the nuclear crisis. The road map called for increased surveillance of the workers’ radiation levels, including a measure requiring TEPCO to periodically report such data to the government.

    Internal exposure is caused by taking radioactive substances into the body via eating, drinking or breathing. Its unit, counts per minute (cpm), indicates the amount of radiation emitted per minute.

    Regulations on preventing health problems caused by ionizing radiation require operators of power plants to conduct internal exposure tests every three months on plant employees who enter areas designated by laws and regulations on radiation-related health problems.

    “My measured value [of radioactive exposure] exceeded the standard value by a double-digit factor. That’s never happened before,” said a plant worker in his 20s, recalling the time he saw the results of a test he took outside Fukushima Prefecture in early May.

    The man, an employee of a company that works with TEPCO, installed power cables near a reactor building at the plant for a month beginning at the end of March.

    The test is conducted by a device called a “whole-body counter.”

    While a normal internal radiation level would range from several hundred cpm to 1,000 cpm, he was told his level was 30,000 cpm.

    High levels of radiation emitted by debris were measured in his work area.

    Although the masks worn by workers are supposed to be changed every three hours, he was told by a management company that he did not have to change his if there was no radioactive contamination.

    He therefore used a single mask for five to six hours.

    He ate in a building that houses an emergency headquarters and accommodates plant workers. At the end of April, he was notified that the building was also radiation-contaminated.

    “I’ve probably taken in radioactivity while eating,” he said.

    After the crisis at the plant began, the central government increased the maximum limit of radiation exposure from 100 millisieverts to 250 millisieverts exclusively for workers at the Fukushima plant.

    However, the amount is a total of internal and external exposure doses. Workers can learn only their external doses via the measurement equipment they carry with them, and it is necessary to also measure their internal exposure level to verify whether their total exposure doses exceed the limit.

    According to TEPCO, there are only three whole-body counters available near the plant. Some workers had to be tested as far away as the Kashiwazaki-Kariwa nuclear plant in Niigata Prefecture.

    As of May 8, 630 workers, or just 10 percent of all workers at the plant, had taken the test.

    The Health, Labor and Welfare Ministry’s Industrial Health Division has advised TEPCO to provide more tests. TEPCO has said it will increase the amount of test equipment on hand to 14 whole-body counters and will also raise the frequency of the test to more than once in three months.

    What don’t they want us to see in it?


    Why are we not seeing ANY of it … TEPCO?

    This is really pretty straight forwards, right?

    Where is it TEPCO? We know you have it, so spit it out already, you are already in deep trouble, and trying to hide this from the world, firstly is not acceptabe, and secondly, it will not work.

      In a statement at about 11:45AM on March 15th on NHK, an official said the No.4 reactor blew up at about 5:45AM and the No.2 reactor popped internally at about 6:14AM (the same dawn and only about 30 mins apart).

      We have no video of either event.

      But we should have video of both
