Hiroaki Koide, Kyoto University Reactor Research Institute: You should think robot can’t do anything basically. It has nothing to do with settling the situation. [...] They can’t be a help at all. [...] Japan hasn’t developed a robot for nuclear emergency at all on the assumption that nuclear accident can never happen. However, some European nations and US have such robots indeed, but their capacity is very limited regardless of remote controlling technology. After all, it must be done by human.

    I would go… To supervise pouring enough concrete around and on Good Fortune Island that it would make the Donner Pass look like a step stool.

    ‘decommission’ Makes it sound like a simple stroke of the pen.

    The cost of decommissioning a working nuclear plant is many times that of a plant's construction, modification, and maintenance costs put together. The cost of decommissioning a triple wreck will bankrupt Japan. It can be done, though the number of copies of remote equipment needed to do the work (and to retrieve the long string of radioactive failures) will be frightful.

    It can be done if the people of Japan decide to bite the bullet and clean it up.

      From what we have seen at Fukushima Daiichi, it is impossible to decommission that particular disaster in this decade, maybe not even for a century or more assuming anybody is still alive in Japan by then.

      Far beyond human and robotic capablities to perform decommission in the traditional sense. The geographic conditions and amount of fuel lost underground makes it a situation a few nuclear scientists theorized might happen, but the rest of the nucleocrats dismissed it as fanciful predictions.

      The only option they will soon discover is to forget any idea of fuel retrieval and work out a method to encase the entire island in concrete and steel.

      It will cost ten trillion dollars to properly accomplish that task. Listening up nucleocrats? The bankers already know it.

      All that's left is half a dozen dry casks with spent fuel.

    There is no option to not 'decommission' (empty word that it is).

    The silence from the USA and the upcoming elections shows the level of corrupt silence engulfing this disaster.

    After the election, there is a likelihood more noise will finally be made, but leading into the election the friggin nukers have got hold of the party tongues .. they haven't mentioned nukes once in all this friggin disaster. HOW CORRUPT IS THIS WORLD!

    Anyone one who has profitted from Fukushima needs to be sent in there. Yes, they will most likely die there. But the process needed to begin nearly two years ago!

    Deplorable. Gutless. Corrupt.

    These mongrels are killing the world and no one is doing jack shyte. No wonder I get pissed off. It's so gut-wrenchingly painful watching the pathetic death of Earth occur. And the pathetic politicians and 'authorities' need to be thrown into the coriums.

    Stop Fukukuku. Stop Nukes. Stop Uranium mining.
    But it's all too late. This poor planet has been irreversibly corrupted. So deeply sad. So sad.

  • But the positive is that even though its not reported, the business people look at TEPCO and see the model of financial disaster. Even the Economist did an article last March stating that no nukes were being built in USA because they are not financially viable therefore there are no investors for nukes.

    It may take longer then we want but the writing is on the wall. Nuclear power is dead. As far as decommisioning Fuku, I think really what the prof is saying is it can't be done. The radiation is too powerful for robots so what can a human do? Run in and turn the wrench once and get a lifetime exposure of radiation. So no work can be done just hope the blob gets absorbed by this planet somehow.

    This site might be able to be decommissioned in 300 years or more if current technology continues to develop making it possible. We have no technology, equipment, or engineering, no materials, physics or capacity of any kind to decommission melt-through coriums. We don't even have the metals that could withstand the radiation to dig them out. We can dig under to mine and fill a trench, collect the fuel rods from the pools, shut off the power, and entomb the entire site. Those are and always have been since 3/11, the only options. But, to do the only thing that may save some lives would deal a death blow to the nuclear industry once people see concrete being poured over another reactor. No pro-nuker is going to push for that.

      "to mine and fill a trench, collect the fuel rods from the pools,"

      SP: Some of the pools might be in removable status by the end of 2014 namely the pools at Units 5, 6, and the CSFP. It remains unclear whether the spent fuel assemblies in ponds at Units 1, 2, 3, and 4 are removable because of issues with their structural integrity affecting removal tools.

      Current removal tools are useless if the fuel assemblies melted together from fires or became bent from falling debris inflicted by the Great Eastern Earthquake of March 11, 2011 and the resulting explosions at Units 1-4. I think Tepkill knows quite a bit about this issue from crane-lowered cameras into the pools, but they haven't shared much other than some murky video footage.

  • Not true, what I saw on the live camera at plugging leaks in the Gulf of Mexico, two kilometers under the water, gives you an idea that we really much … But you have to watch yourself, and not just pornographic films on the Internet, a very successful and take for this money …

      Feliks, How about the blow out 10 miles awayfrom the Macondo Well? The cover up proves that we don't have the technology and never will. How about the melting methane layer which is causing dramatic rise in the ocean floor in the GOM and near Australia caused by rising ocean temperatures and rising oceans due to melt of glaciers and Arctic and Anarctic ice masses and mountain ice caused by Global warming? How about the fractured sea floor in the GOM? How about the massive sinkhole in Louisiana which is growing daily?

      Feliks, There is nothing wonderful about technology that kills everything forever:

      Corexit chemical dispersant used by BP during Gulf oil disaster linked to horrific human injuries

      “But it turns out that this was completely false information, as the Corexit dispersant chemicals sprayed in the Gulf after the disaster began — reports says more than 1.8 million gallons of Corexit were dumped into the Gulf — are known to be severely neurotoxic. But this information was deliberately withheld from Hogan and his team upon inquiry, which reassured them that their several months of diving work was going to be problem-free.
      “In the end, Hogan and his team ended up with permanent injuries that left several of them, including Hogan, completely unable to walk. They also developed neurological problems, as well as vision problems that gradually resulted in permanent blindness. Several members of the team became so injured and hopeless that they actually committed suicide….”

    TEPCO: Ship Unloader Mobile Spent Fuel Crane:
    http://www.crane-manufacturers.com/ship-unloader.html

    TEPCO, have you now abandoned your idea for the Crane Support Structure for SFP4 because the unstable ground under the plant will not support a foundation for the structure?
    http://enenews.com/tepco-will-start-covering-no-4-spent-fuel-pool-tomorrow

    Suggestion, use a modified Boat Hoist or Ship Unloader. Build one, and move it to empty SFP1,2,3,&4. Any Japanese ship unloader manufacturer or ship hoist manufacturer can build what you need. Or modify used equipment, shipped by sea. Get going. TIME is short. Earthquakes are coming soon.

    Some solutions for Fuku do not require hands-on work.
    Construct two parallel Cofferdams 50' apart, and 100' deep. Cofferdams enclose Harbor on three sides, leaving fourth side (the shore) as it is. Cofferdams run uphill from Harbor past Buildings 1,2,3,&4, then complete the rectangle by running on the inland side of Buildings1,2,3,&4. Excavate between Cofferdams, and fill with reinforced concrete. Channel ground water outside of Cofferdam into the Ocean. Between Cofferdam and Buildings1,2,3,&4 sink a series of shallow injection wells to the approximate depth of Coriums1,2,&3 into the mudrock just inland from Buildings. Run pipe from Harbor Bottom to injection wells. Pump sea water from Harbor bottom into injection wells.
    Use Ship Unloader Mobile Spent Fuel Crane to empty spent fuel from SFP1,2,3,&4. Move intact spent fuel assemblies to Common SFP, then (after cooling), to dry cask storage. Fill SFP1,2,3,&4, and Containments1,2,&3 with sand, or with Markwww's 8 element Concrete, and put a lead cover over each pool and reactor. Encase Buildings1,2,3,&4 in reinforced concrete caskets. Cover ground indide Cofferdams with 4' reinforced concrete, cover with roof membrane. Could be done without even 1 worker death. Stops contamination of Pacific Ocean.

    In a nut shell..TEPCO can get more work time out of humans..before they zap out..than robots.
    Robots zap out right away.
    TEPCO considers their workers expendable..they consider all of life on the planet as expendable.

    That is why we need the "Retired Worker's for Fukushima" they are ready to sacrifice all to complete this project. Their president was their in July & said #1,2, and #3 are in worse shape and can topple the fuel pools in the next quake. With #4 sinking 31.5" & leaning, time is running out. We need a boat load of steel supports & a boat load of cement now! Not after the Shawa-Sangri Fault Zone rips these 40-year old 10-story buildings, with 4 million pounds on the 6th floor in 300,000 gallons of water and 500-1534 fuel rods to pieces! Quoting Arnie Gunderson of http://www.fairewinds.org we better have a bag packed if the R-7.0 quake strikes first. Check it out & see the videos & take the radiation protocol on the health page at:
