  • Time Is Short Time Is Short

    There cannot be a single NPP in Japan that has withstood the shaking of the thousands of quakes they are experiencing.

    The quake energy is quickly wearing down the support structures, brittle and crumbling from decades of ionizing radiation bombardment. How soon before an NPP just shakes itself open to atmosphere? Underground broken pipes leaking into the soil? How soon before an SFP collapes? I would say there's a 90% chance a good number of Spent Fuel Pools, both elevated and in-ground, are leaking thoroughly after two years of intensive earthquake activity, and not a thing anyone can do to fix them.

    While we are all focused on Daiichi . . .

    • We Not They Finally

      How soon before we discover that all of the above plus more has already been happening for a year or two?

    Considerable large activity from the Australian, the Philippine to the Eurasian plates. See here graphically…

    • True, it seems to be rippling all along that whole ridge from Japan down to the Philippines and beyond.

      I'm assuming a piece of the planet is NOT about to break off and drift out into space.

      I was just looking at your map link. Wow. It seems like a lot of earthquakes within such a short amount of time. I don't usually ever pay attention to anything like that. Is that Normal? I mean, are there That Many earthquakes across the globe all the time, or is this a new phenomena?

    Edgar Cayce seems to be correct. "The northern parts of Japan must go into the sea"

    Two of the corium mother lodes may have gone down and released tension in the slipping discs. This trend cannot be prevented. Corium going down 10-20 feet per day for over two years. The amount of tritium leaking from other plants throughout Japan must be gargantuan. The half mile puzzle piece just doesn't fit anymore.

    What are we supposed to do besides kiss r asses good bye when #4 pool hits the ground. Looking for real answers. but to keep the post in the right place. The TBS cam was looking rather dim after the quake now its dark. Sometimes fog can do it. Any news from tepco?

      YR typed these pixels of light: "What are we supposed to do besides kiss r asses good bye when #4 pool hits the ground."

      SP: Some of us think the "pool" at Unit 4 consists mainly of sparse remnants of burned up rods. The many fires at Unit 4 in 2011-2012 quite possibly burned away the bulk of the rods.

      The workers may have concreted the lower floors solid so a collapse is unlikely.

      Who knows for sure? Tepco.

        What water didn't slosh out during the EQ's leaked out like a sieve. And all the sfp and reactor fuel was being air cooled within a very short period of time because the water and electrical transmission lines were damaged. After some time fire trucks arrived (after road repairs and debris removal) and that water went straight down to the basement. Repairs were attempted on leaking pools but by then they were fuelless. Attempts to cool what fuel remained behind was made with ocean water. That fuel solidified into granola in the basements. The bulk of it is in veins that run deep underground and out under the ocean. Causing EQ's now? There you have it. It is hard to dispute the facts.

          How exactly does corium cause earthquakes? (Just curious.)

          • Dr. Anne Lee Tomlinson Maziar anne

            “That whole area is subduction zone. Any coriums will eventually hit it.. and get shifted west..inland once that happens. Reflector (Water) controls when-if-why the coriums cause quakes, venting, steam-out events. That's why I watch the NIED monitors. Can generally know a bit before.. going to lose the TBS cam view to smoke-steam-blackout. Is more than 3 coriums burrowing-in the Japan plate system… they have kept good lid on it. That was just a corium-driven eruption. Fuku had one in Feb. it's was 60+ Km North-west of…

            “Fuku plant.. followed the fissure that runs under the #5 reactor.. look back at epi-center that quake,.. and then track the rad-meters! The high-rads walk right back to fuku.. ORIGINATED at quake epicenter. There will be more of these. They getting random BIG FRACKING HOLES developing all over the place! These are corium vents! Well away from the plants… now that corium is in the subduction zone…

            “Tokai.. was supposed to be closed.. 1998.. only it some-how grew from one reactor… too TWO over the years it's been "so-called" CLOSED ! West one.. not sure if that's old one or the "new"..??? Entire top gone, and robot water cranes were working to cool the mess.!
            “Another is between Daini and tokai. WAS a coal fired plant… originally.. now gained a RAD-scrubber on its stack and also lost it's roof like Fuku-4… and has water crane stuck into the top… fuel-pool! This one went BANG a host of DAYS well after the quake. There was news of folks sheltering in this ones turbine building (Photos) on day of quake. So.. figure lost all cooling power eventually… and so went bad. It and the Tokai line-up well for that vid light-show.. in corium-subduction zone ways. Latest word from geological group said that whole entire tectonic plate is crumbling..! GREAT! NOT!

            “the other two.. the two older Chubu-Hams. Even GOOGLE got in the act of attempting to hide those two! They pasted seriously faked icons over them on map-view. Then there's the one leaking. can't say coriums pulled Elvis on those… but there are remote-controlled cranes and such working on them.. says they pushing-out rads so high people can't do the work.

    PS. Science 2.0.
    Try posting something about Fukushima..see what happens.

  • Whilst they're trying to pull the submerged section of Japan plate back from under the Pacific, these trench quakes could hopefully become plentiful – it means they're winning – and while they happen in the trenches nobody's going to get hurt…
    This 3 eclipse month could give Japan / Eurasia it's future back.

  • WHERE IS the rest of the World? Japan needs help and apparently wont ask for it or allow it. I am not sure what is going on, but this is a world/planet problem. The inevitable is coming.

    • We Not They Finally

      It's also a worldwide, powerful, corrupt, self-protective industry. That's what they do. Protect their own secrets rather than protect human lives or the eco-system. You know, at the time of the Gulf disaster, foreign countries offered help like ships to drain off the excess oil, and U.S. accepted no help. Japan is even more isolated. And our understanding is that customs was not even allowing foreigners with geiger counters into Japan. It's beyond outrageous because it is OUR OCEAN, the entire world's ocean, also the entire world's air that they are destroying. There are also things that might have been done early on — like dropping boron and concrete — how effective? — not sure — but they did not even TRY. This has not just been "mismanaged" — it's crimes against humanity.

  • How they play with the facts.

    I was just browsing on New Scientist and found an article answering the question, "Do earthquakes threaten Iran's nuclear facilities?"

    I remembered reading something about Fukushima having been damaged by the earthquake BEFORE the tsunami struck. I found an article in English on a Japanese newspaper reporting in February 2013 that TEPCO had misled the government. The headline reads: "TEPCO misled Diet panel, averted quake-damage inspection at Fukushima plant"

    Further on it says:

    "If the emergency cooling system was damaged by the magnitude-9.0 earthquake, stricter quake-resistance standards would be required for nuclear power plants, further delaying the restarts of idled reactors around the country. The isolation condensers stopped working soon after the earthquake struck, which is believed to have contributed to the early meltdown of the No. 1 reactor."


    But what NEW SCIENTIST confidently tells us is: "Nuclear power stations generally cope quite well with earthquake. They are built on thick slabs of concrete that cushion them, and backup generators are used to keep the reactors cool in the event of an accident."

    Iran, by the way, sits on major geologic fault lines.

  • Revolutionary technologies are being born that will supersede radioactive fuels faster than might be readily believed.

    Shortly before 3/11 a similar increase in EQ's and magnitudes occurred.
