High radiation bars decommissioning of Fukushima plant

Preparations for the mammoth task of decommissioning crippled reactors at the Fukushima No. 1 nuclear power plant are being stymied by continued high levels of radiation from the triple meltdowns there two years ago. [...]

“We have yet to identify all hotspots, where radiation levels are locally high,” [Atsuhiko Kosaka, chief of the Nuclear Regulation Office responsible for the Fukushima No. 1 plant] said. [...]

Fuel is believed to be scattered within the pressure vessels, containment vessels or piping systems, but exact locations remain unclear. [...]

    They can't fix it. This is just a tiny portion of WHY they can't fix it. But they can evacuate people. They can stop lying. They can have their medical community stop acting like Nazi monsters experimenting on kids.

    "Fuel is believed to be scattered within the pressure vessels, containment vessels or piping systems, but exact locations remain unclear." Fuel is actually in blobs surrounded by sandstone and ground water under Building1,2,&3. The corium ceased to be "fuel" in the days right after 3/11/2011. This is what IS clear.

    TEPCO will muck about at Fuku for some years to come, and will admit, finally, that Fukushima Diiachi is beyond their ability to "decommission". The only thing that can be done, is to try to fill as much of the buildings as possible with borated sand, and try to stop some of the outgassing radiation with a concrete sarcophagus.

    But ground water will flow past the 3 Rogue Nuclear Reactors forever, and high levels of contamination will disperse throughout the Pacific Ocean, bringing ruin to the Pacific Rim. If there is something that can be done at this point, TEPCO and Japan will not do it. :(

      and the tidy manufacturer of this failed design, giant, world-class GE, despite Anne's protestations to the contrary, has nothing to say about this calamity …. nothing …. nada … zilch … it is beyond their apparently minimal comprehension that something so awful, something so horrible could go wrong with one (or more) of their nifty machines … and so they say "NOTHING!" Nothing at all … isn't it curious. Rich and powerful Jeffrey Immelt and all his henchmen at Giant GE Corp have nothing to say … how humbling … if they were human …

      and brilliant legal mind, J. Garvan Murtha, of Second District US Court reminds us that nuclear power is so safe … SO FRICKIN' SAFE !!!! DUH!!! I'm a Judge!!! so Gosh-darned SAFE … THAT WE'RE NOT EVEN ALLOWED TO TALK ABOUT IT!!! How smart is that GAR??? Gardy har har!!!

      peace …

  • A friend confirmed that he encountered a hot spot in Japan with readings of 500 microsievert an hour (read from inside his car).

    That is 4380 millisievert a year

    or 4.38 sieverts a year.

    Nucleocrats: One side of the mouth muttering "The second largest nuclear complex in the world is still out of control and we don't have any human means to contain the runaway fuel!" while the other side of their mouth says "Nuclear radiation does not hurt you and we would love to build a new reactor for your naive country!"

    Life in Japan is turned upside down. The inhabitants know it, the nucleocrats know it, and a few outsiders know it. Gamma radiation is not the worst threat now…it's the invisible particles all across Japan in the food, the water, and the air they breathe.

    The same fate awaits everyone on the planet as nuclear disasters continue to mutanize, kill and shorten the lives of billions of innocent victims.

    Move the Doomsday Clock to 1 minute before midnight.

    IMO, the biggest engineering success at Chernobyl was the sand filled rooms which existed beneath the reactor prior to the accident.

      Agreed, FA.
      Sand may yet play a large part as the Fuku-drama plays out:
      Sand can be blown into Reactors1,2,3,&4 via plumbing (without removing the plugs from 1,2,&3.)
      Sand can be dumped into SFP1,2,3,&4 on top of piles of fuel pellets spilled as damaged fuel assemblies are removed.
      Sand can be blown into hallways, such as those seen in this video.
      Sand can be blown into the Torus basements, to cover melted fuel that dripped from failed down pipes.
      Criticalities will become deposits of black glass.
      Sand can settle to fill any voids.
      Sand can help soak up radiation, stopping some of the rays from exiting the buildings.
      Sand will play an important part in what follows after TEPCO admits that the plants are too contaminated to "decommission".

        Sand would also help keep small radioactive particles from circulating in the wind all around the facility.

            16Penny, read "The Wars Of Gods And Men" by Zecharia Sitchin, Fig. 106. The Sinai Peninsula is still covered with pieces of black rock or glass left over from an ancient atomic war amongst the Anunnaki, left in charge of Earth by their unwise fathers, Enki and Enlil, who used to fight with each other for Earth using more peaceful means. I ran into Zitchen in 1978, when "The 12th Planet" came out. Read all his wonderful books. Big fan of pre-history. Will the Anunnaki be allowed to return to Earth? No, not if they are still the backward race they were when they created humans to be their slaves.

      Finally someone brings up sand. All the time I have that picture of an artificial sand dune on top of Fukushima-Daiichi or Chernobyl in my head.

      A giant sand dune instead of a Chernobyl-style sarcophagus wouldn't develop cracks and remain always tight. But the outer layers, where wind and water are trying to reshape it, would need constant replenishment. That could keep some humans busy for the next million years (if there are any left.)

        Cover Fuku with a giant sand dune? Not a bad idea notion, maxli. Suck the sand from the Harbor or Pacific Ocean bottom (it is contaminated anyway) and pipe it to completely cover the Fuku NPPs. Spray concrete over the surface of the dune to encase it. Would take a century to crack and rupture. Then, do it again. Some humans might still be up to this, in the 22nd Century, if we leave them videoplayers (and the dredging and concrete spraying equipment) to show them how to do it. But not any Japanese, as Japan has made quite certain that there will be no Japanese peope around in the future by incinerating nuclear waste, and spreading radiation all over Japan.

          Why spray concrete over the surface? A top layer of dirt and vegetation will help to keep it in place and reduce erosion – better than concrete could, I imagine.

          What I am not clear about is the role of (rain) water seeping into the sand. Will it sicker out of the bottom of the dune, transporting contaminants with it? Will it be heated up, making a sort of geyser out of the dune.

          The good thing is: A heap of sand is earthquake-proof and more or less tsunami-proof, if sufficiently big. It will never fail as a whole, but only needs replenishment from time to time.

        Maxli,
        "But the outer layers, where wind and water are trying to reshape it, would need constant replenishment."

        They could use compaction methods similar to what was used in Dubai to build sand islands in the sea, then apply several top coat layers with a binder. Maybe the good folks from Texas Brine could spare some of their swamp crudes to spray over it. That is the same as how they treated dirt roads in the past to reduce erosion and wash out. On the top layer I would not use an oil product. Using a clay layer impregnated with (if there is one) a compound that would reflect any radiation.

    The last paragraph is the saddest, no practical application of technology apart from Fukushima, so no investment in technology to fix, no money to be made in other words.
    That sums up mankind, mine for me and no one else.
    Japan you have some of the most high tech people and organizations in the world and your prime minister and emperor need to step to the plate and declare a state of impending doom and that all resources available be brought action at all costs or perish trying.

    16pny, sand…
    "Hotspots around Plant",should be "I.D. hotspots around Planet".
    Adepts, "rishis" witness humanity go up and down x2?x3? since Pangea.. extra normal intervention before… what about now??? no filter for radiation. we filter disinformation here..we're toast !!!

      Not sure where you were headed with that, not trying to offend. The post about using sand outside was to provide a temporary cover while hot spots were identified and with the hope of trapping any tiny radioactive particles on the ground, keeping them out of circulation and possibly damping down the radiation levels as the work was carried out. I admit I am WAAAAYYY out of my expertise here and I try to convey that when I go spouting off.

  • The facts on #1 reactor @ Fuku…
    LOOK!.. they have steam pouring out every vertical travel-type pipe, the torus has water in it, but funny, it's not even close to boiling. There is a steam volcano going-on in the center portion under the former reactor core… where the corium exited the building. The steam volcanic action is pushing up sand… SO much so… that's now filtering-down and out to the sides… and then sliding down the connecting pipes and starting to fill up the torus! THIS IS WHAT VIDS they just did SHOW US!

    Japan is ruined and they know it.. It has to be hard to admit that more than likely, your whole country must be evacuated.. That there is nothing you can do to make this go away.
    But to continue to expose humans , the ocean, the world to this danger, because you refuse to admit this is beyond being solved.. Is insanity.
    Saving these plants appears to be impossible.. So why continue to try?
    Russia buried theirs ASAP..
    Japan continues to prattle about, as if pretending this just can't be as bad as it is, will fix this….
    Insanity..

    Please spout!!. Not discrediting sand moderation.. When you mused ancient Afrcan sandbox, I kicked in with 'far back" history…irrelevent to Fuku.. Emotional rant!! .. I actually can stay on topic!! Is philosophy going to be whats left to discuss?? WoW I'm being a bummer…I'm in a bad mood cause we're screwed….

    All the taxpayers money these nuketards have wasted over this entire BS could have gone to make a worldwide force of workers to prepare the world’s spent fuel into pods and use magnetic rail guns to fire the payloads out into a parking orbit near the asteroid belt. It then could be used later in the century for energy to power mining equipment and then shelter making, as they hollow the bigger ones out. Life inside an asteroid could actually be very comfortable, and safe. I have seen proposals of millions of people using them for shelter as the Human race acquires vast amounts of gold, and rare earth materials for construction of interstellar ships to be used for our inevitable adventure to the stars. Who the hell is blocking this kind of technology and WHY? This is genocide, and there is NO excuse for it! Here is a major option to get the economies of the world back on track, and make the world a beautiful and safe place once again. World governments need to get off their ass, pull their heads out of the sand, tell the plutonium mongers FU, and get this nuclear waste OFF our world!

      I hope for the day when we can use magnetic rail guns to launch politicians into a parking lot orbit. Hollowing out the bigger ones seems kind of extreme, though.

      Oh, sorry. I guess you meant hollow out the bigger *asteroids*.
