      I am interested on the opinion of experts in bomb reconstruction analysis on this theory I saw published by an Engineer in lunaticoutpost Fukushima thread: The explosion in Unit 3 started in the SFP on the right of the image, with the large conflagration that can be seen, the left side of the pool is against the primary containment building, that side of the conflagration ignited the gasses accumulated in the primary containment and created an upgoing “gun barrel” type explosion that moved very large debris several hundreds of meters, as can be seen in the movie of the explosion. Alternatively the spike in temperature created by the conflagration coming from SFP 3 triggered a large criticality in the RPV 3 and blew the RPV.

      Interested in technical criticisms of this…

      All you can see now, when you go to the website you posted, is “live event has ended.” Talk about scary. Is it possible that the 9.0 earthquake was caused by a nuclear accident somewhere in Japan? We are not allowed to see or hear the truth.

      Oil fire

      I read somewhere that the video you posted is not of reactor #4, but is video of the oil refinery in Sendai on Mar. 11. I have quoted two comments below the video on the website you posted and included video of this oil refinery explosion as a result of the tsunam
      • this seems an oil fire to me too, compare this whit the melting down vids off chernobyl!!!

      Btw.

And they that dwell upon the earth shall rejoice over them [MSM], and make merry, and shall send gifts [webshop] one to another; because these two prophets tormented them that dwelt on the earth.

        You just blew your credibility with apocalyptic religious nonsense.
        I appreciate your video, even if it’s highly inconclusive. You jump to conclusions, twisting facts to fit your theories, rather than the other way around.

  • SteveMT

    This is 2-month-old, re-spun news with not much to say about current events. We all know that Japan was lucky with regard to the wind direction. However, the ocean and everything in it was unlucky. Already known fact: the spent cores in Reactor #3 were blown all over. The hydrogen explosion was the minimal and politically expedient answer, so as to ‘not create panic for the entire world’ and keep the sheeple asleep. A better analogy would be to keep the frog happy in the heating pot.

    …WAITING… explanation to four (4) detonations. See the sound video sound – none of my making…

    But not swahili nor japanese, pls.

  • james

    Gundersen is wrong.

    There was too much verticality of the explosion for it to be the spent fuel pool.

    If the explosion occurred in the SPF think about the vectors – the blast would propogate in any direction possible from the point of detotation to the mouth of the pool. Much of that would be vertical, but some of it would be at an angle out the mouth of the pool – dispersing the debris in a much broader fashion.

    No, the explosion of #3 came from the bottom of a “gun barrel” type device, that was able to contain the blast to a almost completely vertical shot.

    Virtually any bomb recronstruction expert (not explosives expert – they just blow things up) would tell you the same thing.

    There are only a couple things in that building that could have created that explosion. The most likely is the Reactor containment. The least likely is an elevator shaft.

    • That’s like saying a bullet, when it reaches the end of the muzzle, suddenly decides it’s not going to go straight out the muzzle, but decides its going to veer off from its straight-forward direction.

      Anything non-vertical would happen after the matter has cleared the [mouth of the ] pool – which happened.

      Like a straight-upwards gun-shot, with smoke around the muzzle right after.

      • james

        Bruce, I must not have described clearly. An explosion generally sends the pressure wave in all directions.

        A mushroom type cloud is formed when the pressure wave is forced vertically either by a particularly violent pressure wave rebounding from the ground into the sky (as in a nuclear detonation) or in the case where the the pressure wave is forced vertically by some type of containing device. Mushroom clouds can form from various kinds of detonations – it depends on how the pressure wave attains it’s verticality.

        Now think of the containment from the spent pool – think of a deep swimming pool. It’s not particularly restrictive, so the pressure wave would travel outward in an increasing arc above the pool. Something like the reactor containment, on the other hand, would send the pressure wave up in a fairly straight vertical fashion.

        Another analogy might be the early “blunderbuss type” guns. They had a bell shaped muzzle and when filled with lead shot would blast a very broad pattern. They weren’t particularly powerful or accurate, but were pretty scary. Subsequently, shotguns were developed with much more restrictive or “choked” muzzles – much harder hitting and much more accurate.

        So there you have it. #3 was either a nuclear explosion (I don’t think it was violent enough for that) or it came out of the reactor core – most likely a steam/hydrogen explosion.

        Of course this means the core is exposed at a minimum, or the RPV was ejected. There are certainly photos existing showing something very large returning almost back down on top of the wreckage, but we don’t have a detailed photo analysis, so it’s very difficult to tell.

  • How “stable” or NOT are reactors 2 and 3 and spent fuel pool #4?

    fuel pool for unit 4 had a big crack supposedly.

    i’ve read that reactors in units 2 and 3 have no cracked containment.

    Rose says all 4 cores on the floor.

    What is the status and what are the real risks? How much radiation continues to be emitted? Are further explosions possible?

    How much radiation is being emitted without explosions?

    Educated guesses?

    Where is the best place to live for the coming collapse? This is a great article and I thank the person who took the time to put my rambling thoughts into print. Now, just add the radioactivity dimension to the possibilities and that brings us to the conclusion that there are zero places for safe living in the USA.

    We should have stayed in Australia. It’s glorious down there even though we almost burned to death every summer.

  • rob

    What was the reason the EPA stopped monitoring?

  • joe schembrie

    Arne, I’ve been learning how virtually all of the reactor plants in the US have cooling pools over their reactor vessels, and how those pools are overfilled with spent fuel rods just like at Fukushima.

    I hope you’ll spend some time in upcoming videos to discuss the probability and potential consequences for a Fukushima-like spent fuel rod catastrophe in America.

  • beachbum

    Got an idea! Why not build 40′ high walls around these plants? Would that keep the tsunami water out or would that keep the cooling salt water in? What would the thickness of these walls be? If they got radioactive, what would their half-life be? And how would we monitor the reactors? I just love monitoring; you know, just sit on your ass and do nothing but monitor. I think that is what the other nuclear plants in Japan are going to do instead of putting them into shut-down. But isn’t that place still rocking from on-going earthquakes? Is this another disaster in the waiting? How about in

    • Anthony

      I agree with your “walls“ idea….I also believe they could have prevented this accident by having the diesel generators COMPLETELY ENCLOSED to protect from tsunamis & other operational interrupters. After Fukushima every backup diesel generator in place should be protected (as suggested above) to prove the industry has learned from this situation.

    • How about build walls, then bring on another tsunami to wash all the radiation away.

      Of course, there are bound to be flaws in this idea …(like, how to bring on a tsunami – use our friendly little HARRPie beams to initiate another massive earthquake, or just wait for the next one …).

      Grabbing at straws …
