Inside Fukushima, PBS Newshour, Feb. 28, 2014: [Fukushima Daiichi’s] nuclear cores are between 600 and 800 feet from the harbor. Three of those cores are now melted down, still steaming hot, their steel containment structures breached. Engineers believe some of the nuclear fuel has melted right through the steel containment vessels on to a concrete basement floor, where it is exposed to groundwater. As the ground water passes through the pump, it gets mixed in with the contaminated water that is used to cool the melted-down cores. […] Each and every day, about 100,000 gallons of fresh groundwater seeps into the basements of the plant, where it becomes contaminated with a witch’s brew of radionuclide. […] no one disputes the plant is steadily leaking radiation-tainted water into the sea. […] There are many things that will have to be done here that have never been done before in order to decommission this plant. […] the crisis has not ended here. In some ways, it is still unfolding.

Interview with Dr. Gordon Edwards, nuclear expert and president of the Canadian Coalition for Nuclear Responsibility, Feb. 23, 2014: At 31:45 in — When the nuclear core melts down, it goes right down into the ground, right down to the bottom of the reactor, sometimes right through the floor of the reactor into the ground below […] At 34:30 in — The fuel [at Fukushima] that melted down into the ground, that’s very, very — so radioactive that no worker can look at it.

  • Some of melted through completely, some of it resting below the reactor vessel, a little is within reactor vessels, but rest assured, a

    Massive amount went into the air, say 50 tons to 150 tons. For those who haven't seen it, here is the proof.

    • john dpugh

      Stock Exactly stock , that is the best guess till now. A lot of it gone into the air is the worst part , as we all know .
      Thanks .

    • We Not They Finally

      AND have always wondered: then WHAT are they cooling? Since all or most of the fuel has already exited out of containment? They're "pumping" water in there? Or the water is just rushing in uncontrollably, mixing with coriums here and there, and then gushing out into the sea? Why would they be "pumping in" water at all since they already have a problem of 1,000 tons of incoming water each day, then uncontrollably gushing out into the sea??

      • they dont give a shit about the water going into ground or into ocean, dilution is solution in their view. Yes they were cooling the reactor remnants, the basement remnants, and the excursion ball o' fun.

        Notice they never were putting water onto No 3….nothing left to cool

        • StPaulScout StPaulScout

          stock – Correct. When 3 exploded virtually the entire contents of the primary containment went straight up.

          • WRONG! The primary containment had gone south into ground.. caused hydrogen eruption, that ignited and slammed-together the breeder plutonium rods in the pool.. they went super-crit due to pressing 6.5 kilos together inside the rods… and exploded.

            • StPaulScout StPaulScout

              PattieB – Based on the fact that the explosion at 3 appears to go straight up, and very large hunks of shit can be seen falling back to earth, I will risk it and believe my lying eyes……

              • Problem is, no hole through roof trusses over the core. The nuclear criticality was rods in the pool that blasted straight up.. and that's where the blast-hole in roof structure is… the center of the spent pool..

              • Also, the entire deck around the PCV and such got blasted south by hydrogen ignited blast.. then the nuclear blast from the pool. The PCV still there in the photos post-blast.

                • PhilipUpNorth PhilipUpNorth

                  PattieB: Yes, photos show plug still in place.
                  Showing also damage from falling crane.
                  Damage from above.
                  Had an explosion this size occurred within containment, the plugs would have gone up into the air, leaving an open containment with no plug.
                  Not what we see.

                  • Can anyone provide a single piece of proof that what TEPCO (and Enformable) has presented as Reactor 3 with bent concrete cap in place, is ACTUALLY reactor 3?

                    Just saying, I have been of the opinion the 3 pool went criticial AND/OR reactor 3 vessel went critical.
                    1) I have searched and NOT FOUND any credible plueprint layout of the Reactor 3 building. The general assumption is that the vessel is dead center from side to side. That may not be the case. A blueprint would clear this up enough.
                    2) proof that what TEPCO now presents at Reactor 3 building really is so. Lots of rabbit holes at Fuku, like to close this one up.
                    3) what the hell where those HUGE multiple chunks of debris flying up after R3 explosions

        Maybe they are secretly pumpin water into the ground, trying to jack up the east side of Japan, so the mountain water will drain the other way. At least they are thinking…

      Oh and "it's in the bag." I do not watch television…PERIOD!

      • AFTERSHOCK AFTERSHOCK

        I did watch the first episode, Ontological. It was doubtless what we'd all expect of MSM's (PBS in this case) treatment of Fukushima. They opened with the usual, "Though most might think otherwise, they're still having troubles at that Japanese nuclear power plant." [paraphrasing] Then, they went on to extol the virtues of TEPCO's undying attempts to address the 'issues'. They interviewed several mid-level managers on what they were doing. One was happy enough to inform us that it will take many decades to address the technical 'problems'. Most would come away thinking a commuter train derailed and someone bumped their head on a window! It's was a total downplay of the ongoing horrors…

    • 21stCentury 21stCentury

      Funny One Ontological 🙂

    • Hehehe.. no, more like old-style light bulb… just jar it once too hard and the filament falls off one of the posts inside and so get your BOOM ! 😉

      • Ontological Ontological

        I always wondered what happens at that moment a standard bulb filament flashes like that. I have observed molten bits on the glass inside, and sometimes there is a partially melted filament coil remaining suspended on the post. Perhaps vaporization, and immediate electrical arcing for a split second. Some flashes are very bright. Do they even make the Edison bulb anymore?

        • unincredulous unincredulous

          I think it's illegal to manufacture them in US now. Probably make them in China all day and sell them here, just a guess.

          No we have to use energy saving bulbs, the kind that uses mercury, I read.

          💡 If that's true, I guess it saves the industrial complex the expense of having to dispose of the mercury legally.

    Fukushima is practically an eternal source of a variety of radioactive materials. If the latter were beneficial we could celebrate the great achievement of TEPCO and the Japanese people! Even the Pacific Ocean would manage a smile. However, we have now sufficiently verified that the opposite is true. What is the contrary of a celebration? Prepare for a long one.
    I do wonder what the eventual goal of ENEnews is? Hopefully it will push on MSM and politicians to take some remedial actions. In the meantime it is a source of information. The best comments from the past three years could by some industrious and clever persons be compiled into a book. With essays by various interested and knowledgeable persons like Gudnersen, Caldicott, etc. As a paperback it might make it to the NYT Best Seller List–non-fiction. And provide thereby some funds for ENEnews.

        WNTF…it's a small world…New Mexico and Japan have more in common that they realized…just ignore the plutonium, radiation, etc. and it will go away…you can always tell the people who don't seem to care much about being exposed to plutonium, or get annoyed by your warnings, that if they smile they will be protected.

    NO check for PU or other alpha radiation! No, they can not check for alpha radiation in those scans we see. Fake courage for the filmakers. The stuff from the fuel in Reactor 3, the MOX..with its PU payload. They can only check some minor amounts of gamma from AM241 the daughter isotope of PU…go figure. The most wicked radiation isotope..PU..an alpha emission..when inhaled or ingested or eaten in food. They (TEPCO, Japan, USA, anyone!) can not tell you if you have been exposed.

  • Hi All! Let me start by saying that this is an amazing site and has been my go-to spot for information regarding this disaster that us still unfolding. I am not sure how I came across it but I have been coming in daily (sometimes multiple times a day) since I discovered it's existence. From day 1 I have been very worried about what we are not being told and like a lot of people on here when I try to talk to people about it I get the feeling they are imagining a tinfoil hat on my head but whatever 🙂 I am no where near educated on nuclear science; can anyone answer a few questions for me?

    1 – What is MOX ? I have seen it referenced in the comments quite a bit and it sound pretty bad.
    2 – I live in Ontario Canada; can anyone direct me to where I would find what the background level of radiation is for my area and/or a site that lists what the current readings are (If they have been testing them)
    3 – I know that I have already been exposed to the crap wafting through the air since 3/11 but could anyone hazard a guess as to how long it will be before this planet is uninhabitable?

    Thanks to everyone for your replies
    Rebeca 🙂

    • Shaker1

      Rebecca, you might begin with http://ccnr.org, the Canadian Coalition for Nuclear Responsibility. You might find that you've been dealing with that 'crap' before 3/11. MOX is a mixed-oxide fuel, an attempt to use plutonium in the reactors that were designed for enriched uranium. Ccnr has information regarding MOX at their site, too. And I'm sure someone can chime in with previous background/current figures here, but besides, I'd look at your provincial government's site as contrast to what is said/you might find regarding whatever actual counts you can be provided by individuals/organizations in your area.

    • Planet took a good size body blow from Fuku, but not a knockout punch.

      1) MOX is the nuke cartels way of trying to get rid of plutonium, it is very dangerous, much more likely to blow sky high

      2) Can't help on that one

      3) This is not an ELE, but 2 or 3 more Fukushimas and I would be ready to throw in the towel.

      ONe of my favorites sites with actionable information and original information, is my own, check it out.

    • fireguyjeff fireguyjeff

      Rebeca:
      MOX is an acronym for Mixed Oxide.
      MOX is a mix of uranium oxide and plutonium oxide.
      It is a newer form of NPP fuel than what was common back in the 60s/70s era.
      What is considered "bad" about it is the plutonium part.
      Plutonium gets more focus as it is considered to be more toxic
      than uranium.
      There is also a bit of confusion in this issue as plutonium is referenced as one of the most poisonous elements, yet many argue it is not. Lots of disinfo out ther on it. And many will confuse the issue of long half life with the poisonous aspect, which is an erroneous assumption.

      A key point here is the idea (I think is true) that 1 microgram of inhaled Pu will kill you pretty quickly from the cancer caused by the Alpha decay.

      There is a paradox of a sort though, in how a lot of people think about Pu. With a half life of about 24000 years (Pu239) and 6563 years (Pu240) nuclear apologists will argue that it is more stable than other radioactive elements, hence safer. The problem of a long half life is that it is harder to detect with conventional (and low cost) detection instruments.

      As far as our safety goes though, I liken it more to making a choice of which type of cancer you want to die from when you are forced to "pick" one.

      Or whether it would matter if the love of your life becomes a full on cocaine addict vs heroin addict.

      The outcome remains the same.

      Personally, I consider the MOX issue a bit of a distraction.
      Even without the MOX…

      • The MOX issue being dangerous takes away the nuker argument of "see, we can get rd of our waste"

        That is the biggest chink in their armor…no solution to the waste, look at WIPP

        • humptydumpty humptydumpty

          Except that now the pro-nukers are claiming the "next generation" thorium reactor will use the PU waste as fuel burning up most of it, it will be carbon free, and it will be totally safe — claims which are patently false and/or untested.

        • Angela_R

          Stock, it appears that not only were they converting the plutonium to plutonium dioxide for use in the MOX fuel plants, in more recent times they may have been adding weapons grade plutonium to the mix.
          Perhaps, I am mistaken and it is my reading that is at fault, here is an extract:

          "MOX fuel has been in use since the 1980s and is widely used in Europe. In September 2000, the United States and the Russian Federation signed a Plutonium Management and Disposition Agreement by which each agreed to dispose of 34 tonnes of weapon grade plutonium. The U.S. Department of Energy plans to dispose of 34 tonnes of weapons grade plutonium in the United States before the end of 2019 by converting the plutonium to a MOX fuel to be used in commercial nuclear power reactors."

          The preceding paragraph is of particular interest:
          "The most common chemical process, PUREX (Plutonium-Uranium Extraction) reprocesses spent nuclear fuel to extract plutonium and uranium which can be used to form a mixed oxide "MOX fuel" for reuse in nuclear reactors. WEAPONS GRADE PLUTONIUM* can be added to the fuel mix."
          * Capitals mine. Check out 2nd and 3rd paragraph under Mixed oxide fuel @ http://en.wikipedia.org/wiki/Plutonium

          Also in this article, attention is drawn to the Flammability, see heading, of metallic plutonium.
