NHK, Nov. 18, 2013: The operator of the Fukushima Daiichi nuclear power plant has begun removing nuclear fuel from a storage pool at a damaged reactor building. Workers placed a special fuel transport container in the storage pool [...] At around 3PM on Monday, the workers started to hoist the unused fuel units into the steel container [...] debris in the pool of the Number 4 reactor building could obstruct the work. [...] The removal work requires extreme caution, as any damage to the units could release high-level radiation.

WSJ, Nov. 18, 2013: “We plan to begin the removal process from around 3 pm today, and work until around 7 pm,” said Tepco spokesman Tsuyoshi Numajiri. [...] The units are kept in a pool of cool water to prevent exposure to air, which can cause the radioactive material to heat up and could trigger a sustained nuclear reaction.

BBC, Nov. 18, 2013: [It's a critical issue] whether the casks remain watertight so the rods have no contact with air.

AFP, Nov. 18, 2013: Each rod contains uranium and a small amount of plutonium. If they are exposed to the air [...] they would start to heat up, a process that, left unchecked, could lead to a self-sustaining nuclear reaction – known as “criticality”. [...] Sceptics say with so many unknowables in an operation that has never been attempted under these conditions, there is potential for a catastrophe. Government modelling in the immediate aftermath of the Fukushima disaster [...] suggested that an uncontrolled nuclear conflagration at Fukushima could start a chain reaction in other nearby nuclear plants. That worst-case scenario said a huge evacuation area could encompass a large part of greater Tokyo [...]

AP, Nov.18, 2013: [...] [Experts] raised concern about a major earthquake hitting during the removal work. Japanese nuclear engineers were on Monday preparing to move uranium and plutonium fuel rods at Fukushima [...] Experts have warned that slip-ups could quickly cause the situation to deteriorate. [...]

Kyodo News, Nov. 18, 2013: Nuclear Regulation Authority Chairman Shunichi Tanaka has said the work requires “great prudence” because the pools are strewn with small pieces of rubble [...] “The fuel has to be handled very carefully. There is a need to make sure that a fuel assembly is not pulled out (from the fuel rack) by force when it gets stuck because of the rubble,” he said.

    the BBC do not say the casks are not watertight….

    quote "experts say it it vital that the casks are watertight so the rods have no contact with air – which risks overheating and possible contamination."-

    Wow. Several news agencies report the same confused bullshit.

    No, the lack of cooling or contact to air _won't_ start any criticality in the uranium. Without cooling the already used and radiated fuel might just heat up until meltdown, releasing it radioactive contents into atmosphere.

    Criticality can happen, if fuel assemblies get deformed and the contained fuel rods get too close to each other.

    Same might happen, if the fuel should melt due to a lack of cooling – the melted blob is just another variant of fuel getting to close and therefore critical.

    Both issues are completely separate issues.

    Mass media seems to report either bullshit or nothing at all.

      What I want to know is what is the time required from removal to cask to placement into the spent fuel pool that could cause nuclear fission to begin. Are we talking about right away or is there a window of between 10-15 mintues to get these fuel rods back into the water? I assume that there is some sort of a time gap here that were not being made aware of.

    The part that worries me is the severe deterioration of the boron sheets between the assemblies. I'm not as worried about the new (cold) assemblies that haven't been radiated yet. I figured they would be the first to be removed, and it seems that they are. The ones that worry me the most are the hot, fresh ones that were active in the reactor before it was shut down.

      Japan in fact had a nuclear weapons program during WW II. At the close of the war, a German sub delivered more uranium, although uranium mining was prevalent in Japan.

      Immediately after WW II, most Japanese abhorred nuclear activities of any kind. There were certain individuals who still embraced a militaristic stance, including nuclear-based ambitions.

      Japan's culture as well as its peoples' attitudes values, and beliefs must be understood by knowing of the Samuri class of warriors in the context of the Meiji Restoration.

      The Atoms for Peace program emcouraged the use of nuclear energy to supply Japan(s needs.

      Today, Japan has one of the largest military budgets. Japan is expected to play a pivotal role in confronting China. Japan was an ally during.WW I.

      There is no intention to abandon nuclear energy at present in many quarters.

            You are preaching to the choir about American exceptionalism and Manifest Destiny.

            All of this nuclear stuff is an extension of the desire to create an empire.

            America has encouraged Japan to forego expansion in serch of oil reserves in the Dutch West Indies and in the Pacific area in exchange for the peaceful atom program with reprocessing activities.

            The idea of fighting communism has resulted on restoring power to those in the military class. Germany too has factions who wish to demilitarized.

            My comment was not meant to imply the Japanese people are more militaristic than some Americans.

            The problem is universal and a failing of our species. Many people in all countries abhor violence while others promote it.

            I see the problem in terms of economic anthropology – an obscure but important discipline. The Alpha male phenomenon leads us to our own destruction again and again since people are too often followers and violence carries a.certain.seduction. Combine tthat with technology and the world sits upon a nuclear tinderbox.

          Very top down society. The present government is a coalition of those who want Abe-onomics and those who want to restart nuclear power plants for economic prosperity. The status quo is preserved for the sake of "prosperity."

          They are one big earthquake away from eternity and so are we. That assumes that the NRC documents were wrong, i.e., that the fuel is still in sfp 4. If not, then the worst has happened already. I doubt that is the case.

    I have a question maybe someone here can answer for me. Under a worst-case scenario for someone living in the Northern Hemisphere with no resources for relocation to the Southern Hemisphere, where there is an open-air criticality that causes the abandonment of the entire site, what can a person like me expect to experience? Under a worst-case scenario, how long would it take for the radiation to contaminate North America, to what degree would it be contaminated and how long can we expect to survive? Considering the social breakdown it will incur, and the toxic air and water, how long can we expect to live under those conditions?


    Report comment

      That is a question of degree. In.a worst case scenario, atmospheric contamination takes about eight days for the initial plume to hit. If it is highly radioactive, radiation.sickness would ensue. Probably, the plume would tecircle the globe on the Northern Hemisphere.

      Panic and food and water shortages would immediately follow. Entombment by sarcophagus would likely be the only means of containment.

      The next vector would be by water. Meanwhile, aerosolation of highly radioactive particles would traverse the Pacific Ocean and would be inhaled. Many cancers would form after two years or many decades. Economic collapse would certainly occur. Medical facilities would overflow.

      There would be a rush to the Southern Hemisphere. Precipitation would cause cesium deposition and noble gasses would cross the Pacific Ocean carrying radioactivity. All hell would break loose….

      Many people would not want to survive. This would result in optional euthanasia programs, again depending upon degree. The air would circulate to the Southern Hemisphere inevitably. You would have a chance down under.

        If the recriticalities are of short duration, and there are no prompt criticalities causing detonations, the precautions against iodine 131would provide about 70% protection against tyroid cancer. Have potasium iodine available for those who are not allergic to iodine. Very small children should not be given potassium iodine. Consult a physician in advance.

        Respiratory protection with HEPA or better ratings would protect against a shower of hot particles. Have an emergency radio and supplies of fresh water and food.

        There are other precautions to take. You can find checklists on the web. Avoid milk during criticalities because of the iodine. Cs 144/137 tends to be deposited by rain and precipitation. Stay out of the rain for sure

            Songie,

            At a minimum we are in for a year of rod-pulling drama. We know the fuel rods are damaged and squeezed into the pools with embrittlement of metals and deformations of rods.

            I see no way to avoid some criticities along the course of action planned.

            We are between a rock and a hard place. If the fuel rods are left in place, we risk an earthquake. If the rods are pulled, we risk criticalities or worse.

            Damned if we do, and damned if we don't. Between the devil and the deep blue sea.

            On the horns of a dilemma.

            I wish it were otherwise. Governments do not want panic, but we must take minimal steps to protect ourselves and prepare. I am not a prepper. But had they been truthful about triple melts on 3-11, I would have been in Rio. They even thought there were total burnups of SFPs and they kept that secret, too.

            They cannot afford panic. Fine. But protect yourself in case things get bad. Look into sheltering.

            If I told you to fasten your seatbelt, you would understand that. At least fasten your seatbelt.

              Socrates, thanks so much for the reply! Judging by some of your other posts, you seem familiar with the industry. So, I appreciate your sage counsel without the fear mongering or sensationalism.

              Living in the PNW, it is tough to hear you and others say stay out of the rain. Sometimes it rains for weeks and months at a time. I have my family on vit c and zeolite. have potassium iodide just in case. Bought a geiger counter. If the grown children would go, I'd be in Uraguay by now. Alas, most family and friends think I've gone over the edge.

              It is my understanding that the radioactive isotopes that get aerosolized and swept up into the jet stream go round and round the North Hem every 40 days or so. If sheltering becomes necessary, seems to me that would mean sheltering FOREVER.

                  In exchange, each country who sends its dry-casked nuke waste to contaminated areas of Japan, will accept a certain number (to be determined) of Japanese citizens in need/desire of relocating out of contaminated areas.

                  If/when Tokyo becomes contaminated, that might not be a bad idea……

                  Socrates, do you know anything about the Baser high particle beam that Shui Yin Lo Phd, particle physicist and the University of Melbourne, Australia (joint patent filed) developed? The university withdrew from owning part of the patent and Yin's patent attorney was visited by the Australian Secret Service and was told that the invention had just become "Top Secret" and any disclosure would be a violation of the Australian Treason Act.

                  This particle beam had the potential extreme high energy levels and was invented for the purpose of destroying nuclear waste. When the patent was filed in the USA he also got a visit from the US State Dept. as the project was moved to Pasadena near Caltech. I read this in the book Double Helix Water by Gann and Lo p. 7-8.

                  Lo, besides being a particle physicist, is also a Traditional Chinese Medicine doctor and is currently doing studies on the effects of Double Helix Water, stable water clusters, that he theorizes might be the precursor to DNA. He probably was attracted to the healing field as he strikes me as a brilliant, kind and enlightened person. Probably had a gut full of the secret service crud.

                  Talked to Kevin Kamps (Beyond Nuclear) about using something like the Baser at Fuku but his opinion was a no-go. He knew about transmutation. Expensive and can't remember what else he said- sorry! The point is that there is technology that could get rid of nuclear waste. I wonder why they don't use it.

            • JoyB, seems to be two factions here. I also believe they built a new facility over the old. There are thousands of workers on site. They cleared off the top story or two and had a news conferance on the lowered structure over a year ago. Installed new cranes and foundation and shrinkwrap containment structure so yeah its gonna look new and the event is being reported. Respect Bo and others opinion but must with due respect disagree. But some fuel might be warped or distorted. I predict some fuel will be left behind and buried down the road when its cool enough. Wouldnt be surprised if tepco realizes all fuel wont be moved. Finally salt enteted entire system so I wonder how stable the common spent fuel pool is. That structure Im sure is not earthquake proof and the boron between the plates must also be damaged by salt water. They should be dry casking everything they can now.

    But what is the good if they remove fuel and put in common pool and we have to abandon site, which looks more likely all the time, why are they not moved further from plant? And since criticality is probable, it fails to compute in my meager brain?
    Don't worry the boron wafers were just there for show and not required? Please explain. Ha.

      It is really beyond comprehension.

      It is a known unknown.

      If radiation caused harm immediately in smaller doses.and you could see it like a tornado, then it would be easier to get your head around.

      Small pox and nerve agents seem like a remote thing until the effects manifest.

      Falling out of a building is not so bad until you hit the ground. Our lives depend on TEPCO and chance.

      Ain't globalization grand!

        If radiation were not invisible and a color-like shades of acid purple-the danger would be evident.

        We are visual creatures.

        As it stands now…

    I wonder if it's a 24/7 operation, or if they need daylight.

      It can be a 25/7/365 operation as long as the lighting is there. The pool, from the media aspects, pictures and video, appear clean and ready to go. We just need there to be no serious earthquake activity during this process……GW

    AFP: Tokyo evacuations if uncontrolled nuclear conflagration? >> Not a good situation indeed. Hopefully we have no major earthquakes over 6.0 when the removal process begins. I assume the assemblies are removed via robotics? IMHO, if I was anywhere in Japan right now I would be a the airport waiting to get the hell out of dodge as we all know that something is going to happen here. TEPCO has no way to pull this off without some sort of a hangup or major disaster happening. God help us all!
