At 45:00 in

Gregory Jaczko, Former Chairman of the U.S. Nuclear Regulatory Commission: There’s very risk significant activities happening in the next several months with the attempt to remove fuel from the Unit 4 spent fuel pool.

That’s a very significant activity, and it’s also unprecedented.

There’s significant structural damage to the Unit 4 spent fuel pool. New structures had to be created.

They’re going to have to lift significant debris from the pools.

These are all very, very unprecedented activities.

    What if most of what was in #4 melted and welded itself to the sides and bottom?

    I think Jaczkos' opening remarks make his position fairly clear;
    (haha, as clear as they can be from someone taking a "nuanced" – read "hedge your bets" – position).

    He is not anti-nuclear. He is not a nuclear abolitionist.
    He wants nuclear that is safe. He wants a degree of safety that in my opinion is not possible in the real world.

    If he speaks against restarts of any current reactor in Japan, well and good. But there are more risks than seismicity.

        at the link it's discussed how he made mention of other nuclear tech such as modular nukes.
        In any case, his remarks at the press club do not suggest he is now categorically opposed to nuclear power. I wish he were.

        I will try and find a transcript of his address.

          Right on there or-well…
          “In any case, his remarks at the press club do not suggest he is now categorically opposed to nuclear power.” Just another shill making the rounds, prostituting his resume.

          Following are some of Gregory Jaczko remarks during Q&A at The Foreign Correspondents’ Club of Japan.
          “In terms of the overall question of impact of the accident. Ultimately it becomes a question of resources. In principle you can clean up and decontaminate and decommission everything essentially back to the reactor buildings, predominantly. It simply becomes a question of cost.”

          “You can re mediate soil, you can move soil, and you can clean decontaminate buildings, you can remove all this material. So, it just becomes a question of how much cost you want to incur and how much dose you want to incur.”

          Fukushima Daiichi assessment: “It’s an ongoing challenge, it is not an ongoing crisis and it will be an ongoing challenge for decades to come. In terms of the reactor safety itself, there does appear to be sufficient cooling. Re-criticality does not appear to be a problem, or an issue of concern.”

          Later and the best yet, “These are all very, very unprecedented activities.” That's code for… ‘we’re/you're fu#ked’.

          I hope Dr. Jaczko feasts on those highly prized fresh vegetables and meat from Fukushima. And, I hope he has some good long runs in Tokyo, in the morning.

    I don´t understand… (or maybe I do and I don´t want it to be true)… There´s the possibility of the end of all Japan, and maybe the entire northern hemisphere, and the whole Earth biosphere… and they DO WANT to remove it piece by piece…

    Do they want the rods that much? Do they cost that much? Are they willing to risk the entire planet just to not to have to dump those rods below a sea of concrete?

    Let´s not forget that the term "SPENT FUEL POOL" is WRONG. The ENTIRE 4th reactor is there… There´s nothing "spend" in that pool…

      Unfortunately they can't just dump the contents of SFP4 beneath a sea of concrete. SFP4 contains not only spent fuel but also fresh new fuel AND the fuel contents of reactor 4 which were removed prior to 3/11 in order for the PCV shroud to be replaced.

      By the grace of god there has been enough physical separation between the rods and fuel debris that criticality has been kept at bay (not counting the SFP 'fire' just after 3/11. If those rods were simply dumped into, for instance, a hole in the ground 100 metres deep (and that is almost unthinkable given the hydrology of the terrain) and then this hole were filled with, let's say a million tons of concrete, the rods would continue to heat up (as they still have much decay heat) then melt and either fission or possibly go prompt critical, and would simply burn their way out or blow the whole shebang sky high showering huge areas with radioisotopes. The contamination released thusfar would be as nothing compared to the contamination released by the contents of SFP4.

      There unfortunately is no simple solution. If SFP4 is left 'as is' it is inevitable that an earthquake will collapse the structure with effect as per above.

      The rods and fuel fragments MUST be removed.

      The risks of removing the rods are HUGE, but not as great as the risk of doing nothing.

      I don't see jaczko as an alarmist. When he talks about 'VERY risk significant activities' the wise might do well to pay attention.

        Believe me, I´m thinking the same as you. I follow this amazing site everyday and I know about the possibility of recriticality in the SFP4. And that´s what gives me nightmares.

        What I do think is that the entire effort is not to protect the planet (and all of us in it) but to retrieve the rods for economic purpouses.

        I know it sounds far fetched, but I don´t think TEPCO is doing anything at all thinking in our safety.

        And, btw, I´m way far south in the world… And I´m as concerned as you are.

        Thanks for the reply. I think you´re 100% right

          Depending on perspective, SFP4 rods are either worthless without very significant amounts of expense in reprocessing, or are priceless as hugely radioactive resources that terrorists would do much to possess.

          Ignoring for moment the terrorist aspect, the amount of expense required to remove, transport and reprocess the rods would likely be so far in excess of the cost of manufacturing new rods as to be economically unviable.

          The rods have to be removed because much, much worse things can yet happen if they are left in place.

        • We Not They Finally

          PB, I don't think the worth of the rods is at issue here! It is spent fuel, more radioactive even than when it was fresh, and in a horrendous state apparently — twisted, melted, fused. They don't want to HAVE the rods. They want them to just go away!!

          The issue isn't that they "want the rods back" — it's that the structure they are in, on the fifth floor of a disastrously damaged, tilted, sinking building, could collapse at any time, and the cooling water run out like through a sieve. That could set off massive new criticalities, as well as start a forever nuclear fire that could also spread to other parts of the plant.


          Report comment

          • We Not They Finally

            P.S. to PB: They cannot just "dump the rods under a sea of concrete" ANYWAY. They can't just dump anything under anything over there. Many parts of the site by now are too radioactive to even get near without dying quickly. And they don't see to have a clue about the CORIUMS sunk beneath the ground or what to do about them. They may well be the source of astronomically escalating radiation pouring daily into the ocean.

            And yes, it's very hard to wrap one's head around!!

            so you're saying the lack of water due to it being sieved out is what will cause criticality?

    Removing spent fuel rods has never been attempted manually, it was always done by computer, however all the computer systems were destroyed 3/12. The Japanese stack their rods differently making them even more difficult to remove without inducing criticality. If humans get close to this area , they are only able to stay a few moments, unless they are suicidal, and there will probably be casualties like the workers at Chernobyl.

    I have been having nightmares about the soggy ground around #4. Whenever the crane gets near the pool to pull out the rods, the soil collapses.

      "NRC Head Jaczko Satisfied With Response to Fukushima Crisis"

      Gregory is a hypocrite. He is yappin too much and placing the blame on Tepco. He may be out of the NRC, but he is pitching the words for the nuclear industry. NDA's and a handsome income have corrupted his thought process. There was a moment in time, just after he was group canned, that he reflected upon his mantra. That has been muddied with money now. He has taken the path most traveled.

      Ex-US Nuke Regulator: Japan Slow on Fukushima Leak

      When the plant was in critical condition with three reactor cores melted and in dire need of cooling water, Jaczko said, Japanese and U.S. officials disputed how much water should be put in because of the imminent leaks of radiation contaminated water and measures needed to contain that problem.

      He said the Japanese government was concerned that the flooding those reactor vessels and reactor buildings with cooling water "would lead to greater leakage of ground water," whereas the NRC emphasized the need to keep reactors cool and under control to minimize airborne contamination.

      Jack and Tom are classmates in fifth grade. Both dream of becoming engineers. They learn from their teacher Keza that plutonium is the most poisonous material in the universe and you cant even stand next to high level radioactive waste without getting killed.

      But Jack has a dream of powering his train set and other gadgets and begins collecting radioactive bits from old smoke alarms and lantern mantels. Finally he has enough to kill everyone in the house many times over and has contrived a device that may blow up and he has no idea how to store the toxic stuff. Tom tells Jack this is not such a good idea.

      The two boys grow up, learn about responsibility, risks, value of life, etc and graduate with high degrees. Tom designs solar but Jack…get this…Jack designs plants that use the most toxic material in the universe that nobody has figured out how to safely dispose of, the contraptions may blow up, killing millions of people…and he goes through with this idea against the protests of his friend Tom and millions of concerned people.

      Clearly, Jack does not have the right kind of brain for engineering and should not be trusted either as a kid or adult, and needs psychological treatment.

      All nuclear engineers are like Jack. Even Arnie was making those things, when a child of twelve with common sense could see the utter foolishness and irresponsibility of playing with uncontainable, uncontrollable, super deadly, destroy the world explosive poison.
