Gundersen: At this point my mind is changing, and I think perhaps on Units 1, 2, 3, and 4 the best thing to do is to keep them cool for a couple more years and then entomb them for 300 and come back. Unit 4 is a different story, we’ve got to get the fuel out…

    Pretty obvious that there will never be any decommissioning nor clean up of any units, it is just physically impossible. The 300 year figure is 10 half lives of cesium, so when all that decays off one could approach the problem from a radioactive standpoint. But once it is buried in concrete no one will ever go back and clean up the uranium or other isotopes that last forever. It will become a nuclear waste site that slowly oozes some level of radioactivity forever.
    But it is not just unit #4 that needs to have it's fuel pool emptied. All the fuel pools need to be emptied for many reasons, most of all they are balanced 100 feet off the ground in buildings that are lucky to be standing.

      Hi chrisk9, I saw a graph which said the Pu-239 decay line is incredibly dangerous and reaches its peak activity in around 30000 years.

      Hi Chris- I have to agree with you on your points. I also figured that once they admitted it was unmanageable and Arnie had come to this conclusion that they would opt for entombment for an indefinite period-likely eternity?! During the next couple years that it takes them to offload the SFP's they should put together a sensible plan that includes layers of material including absorbents,high PF-rated materials for extra shielding,boron,etc. that might help with some of the "oozing"radioactivity you mentioned would be likely and with the right materials layered in between hardened concrete walls of the proposed "containment" that might also fill cracks in the hardened structure that form due to seismic activity,age and the effect of high radiation causing premature degradation of construction materials. It "could" work to at least give us all a break from the constant release levels,whatever they "really are"(?) for only as long as the amount of resources spent to ensure an immense & more than adequate structure, with the highest quality and engineering corps used for what is arguably the most imortant(& tricky) construction/engineering feat EVER with the most at stake for Earth's life forms as well! Just my 2 cents…Take Care-Be Well

      what they need to do is build large " Hot Cells " around each reactor building. inside cranes can dissasemble the reactor buildings bit by bit and remove all of the melted fuel in the process.
      this will be crazy expensive and tepco knows this. what they are doing is trying to figure out the cheapest possible way to get this job done. problem is they will pay out more in compensation from lawsuits than they will save.

      this mess could be contained enough and real work towards cleaning up could start if they would quit screwing around and just do what needs to be done. its amazing how bad the management is here. i mean how hard is it to figure out a game plan for 1-stop emissions and 2-clean up?

    Even if you do entomb you have to stop the leaks or the pacific ocean is toast and their goes the ecosystem and food for one third of the plant.
    They will entomb only because it is the cheapest solution and we all know how cheap they are.

    If you look at the entombment efforts done at Chernobyl, the concrete tomb is breaking down now, cracking and leaking. It seems like a big band aid fix and won't really solve the problem.

      There is no 'entombing' anything at Fukushima. With the constant liquefaction of the underlying geology, no structure can be built that will be light enough to not send the whole site into the sea prematurely. Unless this is the 'final' plan, which it very well may be. Out of sight, out of mind. That always works on the ignorant masses.

      Yes the dome at Chernobyl need replacing. And that dome hasn't been subjected to daily injections of tons of corrosive salt water.

      The Japanese are planning for abandonment. Pulling the fuel out of SFP #4 would be nice, but it will probably just go into the ocean anyway. The US is planning for martial law, as a reaction to planned economic collapse and the inability to hide the real threats from Fukushima.

      Tell 130 million Americans their benefits are cut off, they've lost all their money, there's no more health care and their children are going to die from lethally radiated food, water and air, which they created in the first place.

      Good luck with that, Mr. Next President.

        Arnie was still pushing for a boron filled trench, just like a large bowl, excavated under the entire site as the most minimal step not long ago. I think he is coming to see that neither the technology nor the will exists by TEPCO to solve this with effective, expensive measures. The point of 300 years is in hoping some new and affordable technology has emerged by then to help. His public acknowledgment that everyone has so far failed, including international pressure to accept technical help beyond a small advisory team from Britain and the US, may spark some serious debate. TEPCO may find itself having to show a viable alternative to entombment. Entombment would mean that the nuke industry is batting 0 to 3. Every serious accident results in entombment.

    What a FukuSarcophagus will look like:

    Foundation: Pound in twin steel cofferdams 100' apart and 100' deep into bedrock. Run this around Buildings1,2,3,&4. Excavate material from between cofferdams. Fill with reinforced borated concrete, following markww ideas. Remove from site all spent fuel from Common SFP; and remove fuel assemblies from SFP4, (and from SFP1,2,&3 if possible). Bore slant holes under Coriums1,2,&3. Inject boron to moderate coriums, and to keep them where they are in the bedrock. Fill reactor buildings, reactors, and containments with borated sand, to extent possible. Super heavy structures can be built even on sand or sandstone foundations, as was the Burj Khalifa in Dubai.
    http://en.wikipedia.org/wiki/Burj_Khalifa#Architecture_and_design

    Walls: Install a wall 300' high and 100' thick on the foundation. Reinforced concrete. Build in butresses to keep weight of concrete the structure from tipping or sinking. Fill area between walls with reinforced concrete to complete the 300' tall sarcophagus. Perhaps build in membranes to capture and keep in vapors or smoke. Use Japan Armed Forces to do the work. Come back after 300 years to see what more needs to be done. Thanks Arnie. What we're doing at Fuku ain't working.

      Sounds like you've put together the best plan so far, pn. I remember several decades ago a TV science program about symbols and whether future generations could understand current day symbols. The show especially focused on nuclear radiation. The rad symbol along with the skull and crossbones painted on all the walls was the program's conclusion. Something like that could complete your idea of how Fukushima could be entombed.

      The FukuSarcophagus will cost plenty. Big Brutus power shovels digging sandstone out of the ground. http://en.wikipedia.org/wiki/Big_Brutus.
      Think in terms of using an Army of workers. A dozen onsite concrete plants pumping concrete into the worksite through pipes.
      http://en.wikipedia.org/wiki/Concrete_plant
      Barges of sand and reinforcing steel queued up off shore from the harbor entrance. Since this is affecting the entire world, the entire world will have to pay. (Except for the nuclear industry, which will be hard at work to decommission over 400 reactors worldwide). Fleets of heavy trucks hauling containers of spent fuel assemblies away. 24/7/365 shifts working round the clock. Will take a year (maybe two) to complete.

      Cost? The thing I liked about the way the Soviet Union responded to Chernobyl was that nobody seemed to concerned about the cost of the Sarcophagus. They knew the nature of the emergency, and knew that time was not on their side. They just did what was necessary to get this job accomplished. Fast.

      What has happened so far in Japan? TEP.gov gives priority to readying other nukes to go back on line. Their plan was to take 30 years to deal with Fuku. They are taking weekends off. They say they can't send in more workers because the site is too contaminated. Time to hire the Russians and Americans to get this job done. Invade Japan and get to work. Japan will be ever so happy to turn Fuku over to any who would take it on.

    Is Gundersen having a break down and not able to see the reality of not just the Fukushima Nuclear Plant crisis, but all the nuclear energy plants? These poorly designed, poorly placed, poorly maintained plants are world wide and without the solution when a crisis hits. If tomorrow, we are faced with more leaking, leaching plants, what do we do? The damage has already begun and continues in Fukushima and we have a government more concerned with profit vs people. For goodness sakes they are purposely marketing contaminated food to their own people and other nations.

    In Louisiana, we have discovered that with the blessings of the government, a salt cavern has been used to store petroleum products and RADIOACTIVE debris. The government and the company knew for at least a year that there were problems which eventually became evident when the cavern began to develop into a massive sinkhole. The gulf states are known as Cancer Alley because of petroleum industry caused cancers. This is another fine mess that was caused without the knowledge of the residents. Would Gundersen have the same advice to simply fill them and abandon them for a future time? We do not know all the secret hiding places around the world that have been used to store nuclear debris with no concern for the environment or people.

      @ Michele- If you want to call facing reality as having a breakdown, then i guess Arnie is. He's probably pretty tired by now running all over hell and back trying to get the industry and the world to take this crisis seriously. The fact is, no technology has been developed so far to fix this and the engineering solutions to have properly contained this, such as boron trenches, were not forthcoming since TEPCO has been allowed to choose the course we all must follow. Entombment, at least, may buy us some needed time. It might even get us out from underneath TEPCO since they would, then, likely have to surrender the plant.

    Michele,
    I read an article on the poor crop of cherries this year from your area. I was shocked when I read that producers in the region were planning on importing cherries from Poland to make cherry preserves for various restaurant chains and store shelves.
    http://m.startribune.com/business/?id=162410096
    Recall that Japan received a shipment of 1,000 cases of blueberry preserves from Poland – tested them and found they exceeded their very high safe radiation limits (from Chernobyl) of 100 Bq/kg.

    http://ex-skf.blogspot.com/2012/04/blueberry-jam-from-poland-with-220-bqkg.html

    You can bet that cherries from Poland are also highly radioactive from Cs-137 uptake because plants accept it like they do potassium since the valance electrons in these two elements are the same.
    The global economy is going to kill us all. There is no way to tell where your food is really coming from anymore.

    Honestly if you look at "cancer" as a whole it really is attributable to the nuclear industry and weapons programs. The cancer rates have sky rocketed since we have done all the open air tests and "Power Plants" have been built to feed the nuclear arms industry.

    We have for over half a century been told nothing but lies by our elected officials and the nuclear industries they protect about the need and safety of nuclear.

    If you haven't noticed as bad as Japan and Fukushima truly are we should ALL be worried about a real nuclear war and its more than likely going to start with western intervention into Iran's nuclear program.

    There have been a lot of reports that aren't even being commented on by the west about nuclear missiles being supplied by Putin to Cuba. This has gone completely ignored by the western media and "officials". In my opinion if they aren't talking about it, it is more than likely the truth and they don't want to scare us like the original cuban missle crisis.

    We are going to ALL be killed by nuclear in one form or another whether its fallout from Fukushima or a nuclear missle landing in time square or breathing depleted uranium munitions. Everyone in the world should be begging their elected "officials" to end this madness and bring us away from minutes to midnight.

    I sincerely apologize to the admin if this goes to far off topic, however I personally feel like screaming and this seemed to be a relevant place to do it.

    A very serious entombment plan needs to begin now because any clean-up plan will inevitably fail. One doesn't clean up a nuclear spill. The cores cannot be approached by any technology we currently have for another few hundred years. Without a boron bowl trench underneath and around the site, entombment is fruitless. We simply may not be able to wait around until a better option becomes available to us. Nuclear energy production exceeds our ability to cope with it. So, good answers are going to be hard to come by.
