Radioactive waste piles up at Fukushima nuclear plant as disposal method remains in limbo, Mainichi, October 3, 2011:

[... A]t the crippled Fukushima No. 1 Nuclear Power Plant, high-level radioactive waste has kept piling up amid no clear indications of its final disposal destination.

[...] 4,700 drums of radioactive waste after three months of cesium decontamination [...]

TEPCO has been unable to fully grasp the details such as the types and the concentration of nuclear materials.

Professor Akio Koyama at Kyoto University Research Reactor Institute says, “The density of high-level decontaminated water is believed to be a maximum 10 billion becquerels per liter, but if it is condensed to polluted sludge and zeolites, its density sometimes increases by 10,000 times [100 trillion Bq/L]. The density cannot be dealt with through conventional systems.”

    I first saw this and thought it must be a misprint!

    Theses #’s are astounding!!! What will they do with all this poison?!!!!!

    10.000.000.000.000 Bequerel…how high can this go until it is saturated?
    10.000 times higher
    100.000.000.000.000.000 = 100x10e15!!!!or 10x10e16!

    INCREDIBLE!

    Their solution is to burn it in the middle of Tokyo so people living in Tokyo and everywhere downwind (US, Canada), will be strongly affected in the long term.

    What are they going to do with it???
    Nothing!
    Nothing can be done with this crap. That’s what makes nuclear power sooooooooooooooooooooooooooooo
    absurd!
    It creates lots of toxic waste….that needs to be cared for forever!
    TEPCO will have to pull out their well hidden wallet and pay for the building of recepticles for this crap….and pay for the technology to figure out a way to get the toxic shit into the containers!

    “TEPCO has been unable to fully grasp the details such as the types and the concentration of nuclear materials.”

    This line REALLY pisses me off! TEPCO fully grasped,…you MORON,…they only failed to DISCLOSE it! Talk about giving them ALL an out! Just like Steven’s take on Soldiers,…they’re NOT to blame,…they didn’t know! I’m outta here!

    Off to the clinic to help the walking dead!

    • StillJill, Calm down girly, We know they knew from the beginning, they they almost abandoned the plant in first days !
      Gotta keep on a face so the powerful can get out quietly !

      LOL StillJill anyone reading that might think the military guys were swaggering around with nukes in their ammo belts looking for babies to incinerate. That kind of wholesale thinking has been responsible for more misery throughout the ages than all the other sins combined. No doubt there are members of the military who sign up specifically for the promise of violence, but you might first direct your focus on street gangs, organised crime, and the most dangerous of all, the mass murderers in positions of power who either by their sociopathy or stupidity currently threaten all life on this planet.

      Like MOST ordinary folk, MOST of the military are decent and good natured, with a visible commitment to keeping the peace. How they are used by TPTB is another matter, and most often beyond their control (once you sign up you are bound by law and duty to follow any ‘legal command’ regardless of whether you understand the reason/s behind it). It therefore does pay to have a basic grasp of what constitutes a ‘legal command’ just in case you are unlucky enough to find yourself under a ‘rogue’ commander.

      As I mentioned to someone else here, the fact that we can discuss such matters freely is owed in no small part to the sacrifices of those who served when democracy found itself in the long dark shadow of fascism. What we have allowed democracy to become since then is no fault of those who saved it, neither are they (or their kind) to blame for the multitude of problems facing society today.

    in case anyone asking where the corium or “the metal formerly known as fuelrods” actually is: more or less is in the sludge.

    maybe it could be reprocessed to nice little warheads or just fuelrods…..

    Then they better get busy trying Brown’s Gas flame as a deradiation method.

    One would think that with all the technology and industry which Japan has, they’d have done this by now, and have it ramped up to an industrial scale.

    Even secretly, if necessary, since the technology threatens the nuclear waste storage industry, and possibly the energy production industry itself.

    I hope the professional didn’t speak in “billion”, instead he should use GBq (Background: Europeans count “Million, Millard, Billion, Billard, …” while in US there is “Million, Billion, …”

    So the activity of the water is 10GBq/l, and the higher-active, concentrated sludge has 100TBq/l

    Maybe I am missing the obvious. If the sludge is 100 Trillion becquerels, doesn’t that mean it would kill you instantly if you even stood beside it – or within 100 feet etc? I mean when I heard the ocean contamination measured at 10 million becquerels was extreme and dangerous, 100 Trillion takes even that to a whole other level. So since no one was *vaporized* to death by the 10 million figure and no one has died instantly ( to my knowledge) being beside and handling this 100 trillion level sludge, aren’t the facts starting to suggest radiation isn’t as lethal as we believe?

    Keep in mind I am just focusing on instant death by radiation. Until 311 I had always believed radiation was a lethal force – period. The facts no one is perishing left and right in the face of these huge numbers has me perplexed and open to changing my understanding of the situation. This openness and pondering in no way diminishes the reality of the long term damage and ultimately death that unchecked radiation presents.

    Perhaps the radiation expelled in a bomb explosion is profoundly higher than the 100 trillion being reported in this sludge? Maybe 100 trillion becquerels is considered low level?

  • Anthony, people aren’t taking their coffee break next to the nuclear sludge. If work needs to be done around that area people are paid a months salary for a couple of hours work as they reach the limit of exposure that quickly. Tepco subcontracts workers through temp agencies based in sketchy Japanese neighborhoods. They hire drug addicts drunks and criminals who are uneducated and desperate for a quick fix of cash. Look to older enenews articles to confirm. Those workers will crawl back into the wood work to die a painful cancer death which will not make the evening news.

    Green tea anyone? While your gardening?

    Cesium-tainted Japanese Green Tea & Gardening Soil Being Sold By Lowering Levels

    Japanese green tea and gardening soil with high radioactive cesium content are reportedly being sold, mixed with non-tainted ones to reduce their overall cesium level.
    The Japanese daily, Tokyo Shimbun revealed in its own study on Monday, that some retailers are mixing green tea and gardening soil produced near Fukushima Prefecture, with products that originate FAR from the quake-striken region.
    This comes as the Japanese government is restricting sales of products that contain cesium exceeding the safety limit.
    However, the newpaper says currently there are no regulations banning the mixture of tainted products with non-tainted ones.
    Meanwhile, Japan is about to add a new political party to its parliament next month tentatively named the Green Party which supports abolishing nuclear power plants.

    There’s hope in that last sentence though…

    Exodus of Doctors, Nurses adds to Fukushima Prefecture Woes:

    http://www.yomiuri.co.jp/dy/national/T111003004497.htm

    Since the start of the crisis at Tokyo Electric Power Co.’s Fukushima No. 1 nuclear power plant, hundreds of doctors and nurses have resigned from nearby facilities, according to a survey by an association of Fukushima Prefecture hospitals.

    Their departures have resulted in some hospitals in the prefecture suspending nighttime emergency care and other treatment services, the association said.

    The survey found that 125 full-time doctors had resigned from 24 hospitals in the prefecture, or 12 percent of all doctors working at those institutions.
