Research and Development Road Map for Decommissioning Units 1-4 at TEPCO’s Fukushima Daiichi Nuclear Power Plant, July 30, 2012: Removing fuel from spent fuel pools is possible […] However, the spent fuel has been exposed to seawater and maybe deformed or damaged […] it is assumed that most of the fuel is intact […] As fuel assemblies in spent fuel pools were exposed to seawater and possibly damaged, assessment of the impact of safe and long-term storage is required. […] Fuel assemblies (Units 2-4) stored in spent fuel pools were exposed to seawater, and those at Units 1, 3, and 4 are possibly damaged due to falling debris. […] Investigating the impact of spent fuel that was damaged or exposed to seawater on the chemical treatment, waste treatment, and product collection processes. […] Future processing and storage methods for spent fuel removed from the spent fuel pools will be decided on the basis of assessment of its long-term soundness and the results of research and development […]

Examination of Methods for Processing Damaged Fuel, etc. Removed from the Spent Fuel Pool, Page 22: Fuel in the nuclear reactor building pool is thought to be contaminated with saline from seawater, and part of the fuel may even be damaged or leaking due to the collapse of concrete fragments. […] Specific actions 1. Study of past cases related to damaged fuel, etc. […] 2. Examination of the impacts of damaged fuel, etc. […] The impacts of impurities (saline from seawater, etc.) absorbed to damaged fuel […] 3. Examination regarding the handling of damaged fuel • For fuel that is severely damaged and cannot be handled by existing reprocessing facilities, methods for their acceptance, storage, and shear treatment will be examined [...]

    The good news here is that Arnie Gundersen was right on the money. I feel better now knowing that there is a plan, and the Japanese seem confident of some success.

    TEPCO have failed spectacularly at every single thing that they have done, no matter how minor. I have no faith in their ability to extract the fuel from SP4, which is an incredibly difficult task and a source of acute immediate peril for the whole planet.
    I wish that I could share your optimism.

  • The picture in Enenews's summary is from the docstoc document. This 92 page document is a provisional translation from Japanese.

    The blue arrows in the picture are incorrect. The sequence is,
    -upper left
    -lower left
    -lower right
    -upper right

    With this adjustment, the picture now makes sense.

      Either that, or it's a grade-schooler's plan on how to pack a school lunch. If we could just find the sandwich and the apple and the cookie, we would put it in a paper bag, and then into a knapsack, then store the knapsack in the coat closet. Well, that's IF we can even find the apple and the sandwich and the cookie. If the rats didn't chew through the paper bag or the rain turn the lunch into mush or if the coat closet hasn't already fallen apart and washed into the bay.

      What bother even publishing this? To infuriate people?

    I have a sense that many great minds are at work on this (probably on their own and somewhat independently) and probably from many different countries too, and this does give some hope. However, charlie3 is right. TEPCO is not competent enough to be in charge of all of this mess. It must be taken over by some new body of scientists/nuke folks/governments or whatever to handle all of this from start to end. The only way that I will have any faith is if Arnie Gundersen personally works side by side with them — although not on-site, obviously. But I almost believe that any plans put together should have his okay or approval regarding the process that will take place. (Guess Mr. Gundersen has earned my trust).

    I don't think anything is going to improve until:

    1. A group of world leaders get in front of cameras and admit just how bad things are.

    2. A bunch of scientists and engineers that were ditched from nuclear corps and universities for telling the truth, are put in charge of the shutdown.

    THEN where do they store the fuel containers? Are they going to be on land storage??…or dumped offshore from barges? Noted the number of barges with fuel containers processed from Fukushima at the harbor..even to photographs of robots to pull out rods from water storage. So where are the fuel rods after they are containerized..going to be stored? They will need monitoring…or do I have that wrong?

    I let my nephew and his friends take my boat out a couple of months ago. They forgot to retract the ladder on the swim platform after it had been immersed in salt water. When I saw it the lower portion had salt crystals all over it and the lower portion would not telescope back into the upper portion and fit under the swim platform as it was designed to when not in use. I had to spend an hour cleaning the salt crystals off to get it retract. I assume the same thing has happened to those fuel rod in their racks in the SFP. They are not just going to slide out when they try and remove them ( and they can't scrape the salt crystals off and put some vegetable oil on them to help them slide either as I did). If they have been bent or distorted by falling debris or due to being rattled around during seismic events it will be even more difficult to extract them if not impossible.

    Someone was asking about the ice wall, here's a .pdf document showing the vision. No that it makes any sense (pg.14).

    Can't find the 'Mid and long Term Roadmap towards the Decommissioning of' in the wild, have to pay to see it.

    The other doc for long term decommissioning is a R&D mission because of all the problems involved in dealing with highly radioactive debris removal (melted cores).

    The biggest problem is stopping the saltwater intrusions from corroding the concrete and metal so there is something left to work on in the decades to come. Maybe that is why a seaside chemical seawall is being built first, to block out the saltwater. Later the ice wall is to join the chemical wall to form a perimeter wall.

    After that, everything hinges on the fixing the leaks in the containments so they can hold water right up to the top of the lids. Without shielding water, no work can be preformed.

    The fuel pools, no matter what the troubles, seems like child's play compared to the melts removal.

    Then it is play hide the salami for hundred of years as you move used fuel and melted core pieces around trying to store them safely. Even spent fuel casks can only last about 80 years before having to transfer the contents to new ones (so I read).

    Nuclear power to expensive to deal with, to dangerous to risk.

    My Daiwa fishing reel corroded from sea water. I just tossed it out. This never happened to my fresh water fishing gear.

    When you consider the chemical reactions, the heat, and the radiation, the metal is compromised and the the fact that many rods are deformed, some even vaporized, you have a situation that is well beyond current metallurgical engineering capabilities.

    It would be impossible to improvise a three-hour opera at the performance. This job is impossible without changing the laws of physics and chemistry. Yet, like an abscessed tooth, it has to be extracted one way or the other.

    The fate of the world is in the hands of TEPCO.

    The so-called 'experts' were singing a different story before I published 'Fear and Loathing on Fukushima Unit 4' found here:

    In case you forgot the prepared, orchestrated propaganda of RT, Arnie Gundersen and InfoWars on Unit 4 let me remind you:
    http://hatrickpenryunbound.com/?p=3876

    Also let me remind you that Arnie "I have read the NRC FOIA documents but won't discuss the cover-up within" Gundershill of Scarewinds is NOT the leader of the true Anti-Nuclear movement….Kevin Blanch is AND he talks about Plume-Gate.
    Arnie, Alex Jones, RT and other 'alternative' media outlets won't.

    Search 'controlled opposition' on my website and please read if you do not understand how they operate….hatrickpenryunbound.com

    I want to thank all the REAL anti-nuclear activists that have taken the time to read and understand Plume-Gate, the 'silver bullet' to shut down nuclear power and the world's largest PROVABLE cover-up with 1.3 million estimated US fatalities by the year 2030.

    Plutonium half life of 24 thousand years aprox. is horrible enough on its own. Enter the daughter isotopes it produces U 238 with a half life of 704 million years, and U 235 with a half life of 4.47 billion years. Our Sun will have gone red stage, and swollen large enough to have consumed the Earth by then! So yes it is definite that the effects of this catastrophe will go far beyond our tiny Earthling existence in the grand scheme of the Universe. It is my personal dream to use rail gun tech to launch these fuel rods in metal dry casks, or the baskets they plan to place the broken rods in, and send them out for safe storage in the shadows of certain larger asteroids, or out in the icy realms of the gas giant planets. Then one day when our plasma fusion technology is perfected; use the plutonium to build truly safe thermo couple power plants for automatic, robotic ion/electron wind probe ships designed to prospect the mineral rich asteroids, and outer solar system moons for high tech materials we Humans can use in the future. Alas will mankind survive? This of course would require full planetary co-operation. These days with the carefully programed and paid off muclearcrat shills protecting corrupted governments, this is highly unlikely! Even though the benefits of doing this would be millions of good jobs, and high tech positions, and a decent space program involving all of Earth's most brilliant people, and not just the Elite.

    This was Arnie's view on data from the SFP's on August 26 2011.

    http://vimeo.com/28222223

    IMHO, #3 released 100% of the reactor and the SFP in the explosion event and subsequent days after.

    Thats MOX folks…

      Unit 3 reactor and spent fuel pool BOTH went skyward with the big detonation, according to Arnie's video. I remember that he had mispoken himself about the sodium rather than the cloride causing the sulfur. He corrected himself in the video you posted.

      At that time SFP #4 allegedly, at least, was in better shape, according to readings at the time – provided by TEPCO. Those readings were discussed in the video.

      Much MOX fuel must have vaporized on the Ides of March, 2011. The status of SFP rods remain in doubt, except that they are damaged.

      If SFP #3 went up, which I am sure some did, that alone would have aerosolized, while #3 reactor core's contents were blown sky high. I am sure that hot particles are in my lungs.

      The world's economy could crash out if the third largest economy (Japan's) is facing massive contamination. Chunks of plutonium lying around!

      The US has Hanford and others, so we are giving the Fukushima disaster "professional courtesy by keeping quiet.

      Overall, we are toast. My lab guy committed suicide after taking fingernail samples of a child who was exposed in Japan for a year and one-half after the 3-11. He found uranium at high levels. I also take note of the sudden unplanned exodus of certain high level officials and their families to the Southern Hemisphere.

      We are being lied to to protect the guilty – a wink and a nod. I could taste the stuff on the West Coast. It isn't in cold shutdown at all.

          CodeShutdown,

          Sure. I had several professional consultants. For example, a toxicologist, an epidemiologist, a few physicians, and a lab expert. Arnie and others provide nuclear engineering insight.

          My lab expert helped a family to return to the US from Japan. They worried about levels of radiation in their young child. Unfortunately lab results confirmed their worst fears by analyzing levels of uranium in the child's fingernails. The lab expert became depressed. I was notified that he ended his life.

          I have supported epidemiological studies to assess the effects of routine operations of NPP in California. We have reactors that have had periods of shutdown and reopening where incident rates of signatures disease statistics can be compared, notably childhood leukemia. From Chernobyl studies, we know exactly what to look for. These studies used existing government data. You may Google Joseph Mangano's studies and PubMed.

          SONGS was closed in part based on 60 or more European studies. Germany, too. The closer you live to a NPP, the more likely you will sicken.

          All of this is very depressing. I try to deal with issues philosophically to fight another day. I was exposed in Nevada in the 40s and 50s as a child.

    From my understanding of Arnie's position; Unit 3's reactor didn't explode, its internal over-pressure due to melt down lifted the primary containment cap and vented hydrogen into the secondary 'containment' (the tin-shed building).

    I've analysed the sound of the explosion from the video and there are three distinct explosions:
    Starting with a slightly soft-starting Bang! <1.9 seconds later> a really sharp Crack! with the highest sound level of the three then <2 seconds later> Another Crack! which was mixed up with the chaos of the earlier blasts and sound level almost as high as the second. Then starting 3 seconds after that is the sound of all the rubble that had been thrown up into the air crashing back down to earth, back into the building, and the SFP and all around.

    The hydrogen exploded (as it did in 1, 3 and 4) and that explosion jiggled the spent fuel some of which got too close together and created two prompt criticality events within the SFP. Those criticalities wrecked the SFP and blew spent fuel out and all over the place.

    In the mean time reactor 3 with its leaking lid and stretched hold-downbolts just quietly went on loosing its coolant, and eventually melted down and out without much more fuss. Any hydrogen (mixed of course with melting fuel products) vented direct to our air supply via steam and gas through holes in the bottom of the containment and drifted out of the wrecked reactor building towards Tokyo and Washington. Like…

      It stuns me that over two years later this page is still debating the explosion at reactor three. I spent an inordinate amount of time here and in many other venues searching for answers in those days. It is apparent to me that they have never come clean on three.

      No doubt that pool went up big time, and the reactor likely as well.

      ITs criminal what has happened here, and shameful that they just plain lie and deceive.

      What about yesterday? How is SFP 4? And whatever is left of three managing after that shake up? "No damage" yeah just like SFP 3 and the reactor was fine after the big EQ.

    from memory: zirc fire in sfp4 on march 15 (reported to IAEA by Tepco, exhaustively discussed by NRC in the ensuing days), first water added march 28 (reported by Tepco, discussed in the NRC transcripts and emails). Now i'm just an old geezer with an old geezer's memory, so maybe i have it arse about face. But how does a spent fuel pool containing an almost new reactor core (100 tonnes or so) survive for 13 days without water being added? The NRC asked Tepco whether the core had been inserted into the pool as a single unit, and was told it had. So this doesnt add up. The NRC said there was no steam coming out of sfp4 for days and days. How did the pool stay cool enough to emit no steam – maybe it was full of very heavy water, ha ha. Now we have pictures of a pool that still exists, (and was not, as the NRC believed for two weeks, obliterated in the blast that wrecked the reactor 4 building). The pool is full of water, with debris on top of the rods. Let's hope we live in the age of miracles and this is true … any opinions? Once again, hats off to hatrickpenry, and won't someone nominate him for a Pulitzer.

  • Fukushima: Questions and Answers
    Q : Why after the accident, all the reactors were not entombed?
    A : Because of the pools fully loaded. There where hope to remove them before entombing the rest.
    Q : Why the pools are not still emptied?
    A: Because ceils and even the cranes had collapsed on them and made it difficult to do it.
    Q: Why does the Pool number 4 in worst state them the others?
    A: Because it was loaded with new, therefore hot rods. The core was emptied and the rods were on the pool, which dried and caught fire, probably melted trough the pool floor after the earthquake and tsunami, destabilized the structure that was not prepared for such a fire.
    Q: So how TEPCO is going to fix this? Are they going to empty that pool?
    A: Difficult to say so! Even the cranes in operation on the site are remotely controlled. Yet with the new structure they built on top of number 4, they will probably have more radioactivity trapped in. It will require a hell of precision to extract these rods which are certainly in a bad shape, and of cause, remotely! Technically impossible, but what choice do they have left if not try…


    Report comment

  • Q: So success is not at sight?
    A: they are very aware of failure. The structure they have built is not unnecessary anyway. It is most probably a beginning of a sarcophagus, and in case things go wrong, they have less than 25% to complete before it start spewing unsupported radiations. They can still also berry the pool with cement since they built an access to it. So the structure is totally independent to the pool, showing that a certainly collapse of that pool will not affect that structure, and still give access to do all the entombing work to contain it.
    New technologies are the most wanted to limit Fukushima consequences.

      "Success" at what?,They've been largely successful re; their "mission to contain the truth from public knowledge.

        A sarcophagus is NOT even feasible,nor does ANY existing or suggested structures CURRENTLY planned or even considered hold ANY value towards stopping or containing the ongoing releases to date. Some of the proposed containment & entombment ideas forwarded by people OTHER than those actually working there or coming up with plans TEPCO & the govt. of Japan on the shoestring budget may have limited potential for some measures of success-but not at the current level of haste & concern displayed by those responsible who wouldn't give up their paychecks or management bonuses or the required level of spending & the huge sums of money necessary to implement anything that "might" work. IMO(and many others)TEPCO EO's & TPTB won't even make anything close to the selfless costs & efforts or personal sacrifices needed until they see their spouses or children die or have their arms or legs fall off as a result of THEIR actions/accidents,etc. first!!
