US Nuclear Officials: Fuel fragments were likely ejected from cladding at the 3 Fukushima reactors — Particles of fuel resemble highly radioactive ‘mystery black substance’ often seen in Japan since 3/11 (PHOTOS)

Published: December 10th, 2013 at 1:25 pm ET


Interview with energy and nuclear policy analyst Mycle Schneider, Dec. 9, 2013 (Emphasis Added): Record radiation levels have been detected at the Fukushima nuclear power plant […] Mycle Schneider, an independent analyst on energy and nuclear policy, talked in detail about the situation. […] the latest cases were an indication that “there are many places where there could be very high levels of radiation.” This case, according to Mr Scheider, also indicates that “other places might have received fractions of highly radioactive spent fuel pieces.” […] “it is obvious that we are facing the situation that is completely unprecedented, unprecedented in scope and unprecedented in complexity.” […]


NRC: NUREG-2121 “Fuel Fragmentation, Relocation, and Dispersal During the Loss-of-Coolant Accident”, Published March 2012: In light of recent results from the U.S. Nuclear Regulatory Commission loss-of-coolant accident (LOCA) research program […]  a comprehensive review of past research programs for observations related to the phenomena of fuel fragmentation, relocation, and dispersal [was conducted]. […] Fuel dispersal is the ejection of fuel fragments or particles through a rupture or opening in the cladding. […] Fuel fragmentation—that is, fracture of the fuel pellet into large fragments—appears to occur as soon as any meaningful amount of burnup is accumulated, as low as a few megawatt days per metric ton uranium. Fragmentation in irradiated fuel occurred in all but one case for which it was assessed. The only case in which it did not occur was in an unirradiated fuel rod. […] The review of existing data confirms that fragmentation appears to almost always occur, regardless of burnup and other variables […] Said in another way, the review of existing data confirms that fuel fragmentation and subsequent relocation are real physical phenomena expected under LOCA conditions. Therefore, given that these physical phenomena are expected and with the move to best-estimate methodologies, accounting for the impact of fuel relocation is appropriate. […]


NRC: Generic Issue Proposal — Fuel Dispersal During a LOCA, Oct. 7, 2011: Fuel particles can be expelled from ballooned and ruptured fuel rods during a LOCA. […] the phenomenon can occur well below the regulatory limits […] Potential damages include (but are not limited to) increased radiological activity levels in the coolant and containment, displaced heat load potentially causing flashing of coolant (particularly at pump inlets), erosion of pump components due to entrained fuel particles […] Fuel dispersal is expected to occur in almost every instance where a LOCA results in failed fuel rods […] Fuel dispersal occurred in the TMI-2 accident, and likely occurred in the Fukushima Dai-Ichi accident (based on indications of severe core damage). […] The phenomenon of fuel dispersal is important because of its potential consequences, described above, and because it is currently not taken into account in safety analyses. We believe that fuel dispersal could have a significant impact on debris load, as well as temperature of the coolant, during the reflood and recirculation phases of a LOCA. […]

Could this be why Tepco was required to report that “nuclear fuel material” was in the leaks from the tank farm:

Tepco on August 19, 2013 after a storage tank leaked 100s of tons of water with 80,000,000 Bq/L of strontium-90: “We determined that this incident corresponds to “a case when nuclear fuel material (not in the form of gas) or the like has leaked […] due to an unpredictable event […] per Article 18, item 12 of the regulations concerning the operational safety and the protection of specified nuclear fuel material” (A similar event was reported on October 3, 2013)

Also, the dispersed fuel resembles the mysterious black substance observed in the Tohoku and Kanto regions after the explosions.

    If the problem was just Fukushima, or perhaps even all of Japan, that would be terrible, but not Earth-shattering.
    However, the destruction of life in the Pacific Ocean indicates that we have now passed some sort of tipping point, where the stresses produced by human mis-behavior and natural disaster has overwhelmed an entire ecosystem. The damage is not recoverable. The Pacific Ocean is dying. 🙁

    • We Not They Finally

      I agree with you:The pacific ocean is dying and we lose the ocean we lose life on this planet. We may become the next Mars. Without life and without atmosphere…

  • myau

    On the subject of dying Pacific ocean and slowly but surely of all oceans, I read somewhere that the planktons account for nearly 50% of all the oxygen in the air that we breath, so will this mean that humans will then die of asphyxiation even sooner than dying of developing cancer. How soon will this process take and how does this all work-out physiologically, I shall appreciate any comments from our Enenewsers. Thanks.

    • irhologram

      Myau please see the ongoing discussion of methane/H2S on the nonnuclear thread…including indexing back by one page in the thread. You will see that this process is taking place now. It's not in the future.

    • We Not They Finally

      The process will intensify until what will be will be…Every day that goes bye will lead to the grand finale…Jung many years ago said that man creates his own evil.This is truly creacide.The death of the Creation of this earth.We will progress from Oxygen to methane.Yes and the Satanists will be the last ones standing…

    What Is Happening To Alaska? Is Fukushima Responsible For The Mass Animal Deaths?
    December 10th, 2013

    Why are huge numbers of dead birds dropping dead and washing up along the coastlines of Alaska? Something is causing mass death events among various populations of fish as well. In addition, it has been reported that large numbers of polar bears, seals and walruses in Alaska are being affected by hair loss and “oozing sores”.

    Clearly something very unusual is happening, and it should not be unreasonable to ask if Fukushima is at least partially responsible for all of this. Without a doubt, the Pacific Ocean appears to be a much different place than it was before the Fukushima disaster. Radiation levels around Fukushima just continue to increase. And every single day, another 400 tons of very highly radioactive water gets released into the Pacific Ocean.

  • myau

    Thank you,irhologram, the methane is surely another life threating mess, but I wish to know more about the dying ocean planktons and the depletion of oxygen, any specific advise? Thanks.

    • We Not They Finally

      I thought the death of the plankton will destroy 70& of our oxygen…That wont leave much oxygen but lots of explosive methane gas.

  • I am become death, killer of nuke

  • Hi, I don't know much about anything, but this has been in my mind for ages. Can someone tell me if the huge amounts of water, billions and billions of gallons of water heated by up to 25 degrees F, which are poured out by nuclear power plants after being sucked in for cooling, day in day out, and which surely must affect the top layers of the sea, … have something to do do with this. I agree that Fukushima is having a nightmare affect, but this was going on before. I wrote a blog about this in 2010! Sorry if this is in the wrong place.

    Undesirable, yes the heating effect of the water would be very undesirable. On rivers it would bring up the temperature of the water to a level that some fish might prosper while others might not. Bacteria and virus would then have the ability to flourish in these warmer contaminated waters. There were reports of flesh eating bacteria the last couple of years in fresh water rivers downstream from nuclear power plant discharges in the southeast. For every action there will be a like kind reaction, positive or negative depending on the initial action taken.

    It would be common sense to understand that using Nuclear to heat water is a very bad move, since all the heat created by the burning sitting star, discharges of warm water and then energy produced in the form of electricity created contributes heat to the environment and immediate surrounding ecosystems. ON the edge of the edges of our oceans these sitting stars would have the same tyoes of effects on the ecosystems and ocean currents passing by. Anne has covered the krypton 85 effects on our ozone and surrounding areas too. None of this is good for the Earth and it (Nuclear Technology) does not belong on this planet. 🙁

    • Thank you, Obewanspeaks, that makes horribly good sense. The other thing that occurred to me was that, according to the report that came from Dalhousie University in 2010, the plankton levels had been going down by about 1% a year since 1950 and in the northern hemisphere they had dropped by about 40% by 2010! Apparently we get half our oxygen from the plankton. The researchers said that they thought that this was because the surface layers of the oceans were where the plankton live, but that these layers were getting warmer. The plankton need nutrients to grow and these come up from deeper water by mixing. However,as the surface layers get warmer, they form layers that don't mix properly with the cold layers and the plankton don't get enough food. What I thought was that the 1950's were perhaps the start of civil nuclear activity and that there have been more plants built in the Northern hemisphere than elsewhere. If you have an artificial temperature increase in one layer, caused by the expelled heated water from the nuclear plants, maybe it dramatically affects the way the cold and warm layers slide over each other and the ocean doesn't adapt to this in the way it would otherwise do. The contamination from Fukushima, on top of this is horrendous. Any ideas?

      • obewanspeaks obewanspeaks

        Well I guess anything is possible regarding water flows in the oceans. I am more concerned with the fact that we really do not know the consequences of the radioactivity released from these plants. We have all heard the banana comparisons and then saying it is natural like the sun and cosmic radiation etc. coming into our environment. Yet what we are releasing is nothing like these sources. These radioactive isotopes have been seen in the snow at both poles and they must have some effect.

        The Earth is a pretty dynamic system that we do not fully understand and there has been an increase in the earthquake activity and volcanoes and the core has been very active. There are plenty of volcanoes being discovered under the oceans and the ice sheets at both poles and they are active too.

        The nuclear power plants throw out Neutrinos and they can be detected by special equipment. The Japanese could identify all the signatures from all sources, sun, cosmic, core, nuclear power plants and the fact that they could identify the false energy source we created has me concerned. These babies have mass, not very much, but they might be causing some commotion with the recent core activity.

        Grampybone knows the reactions of radioactive isotopes and behaviors with other matter where it has a magnification effect on surrounding particles, atoms etc. So these released isotopes may being doing things in the immediate ecosystems that we do not understand.

        But the Sun is the biggest…

        • obewanspeaks obewanspeaks

          ..driver of the world's ocean/air circulation patterns.

          The wobble has changed on the planet and that might account for the wild weather swings and erratic jet stream patterns we are seeing now. As the Earth tries to rebalance it will be a wild ride for awhile and hot/cold transitions in all flows/currents will be even more erratic.

          With all this "Negative Earth Behavior" expected/predicted in the near future and that we can document, it just makes sense to shut down the Nuclear Industry and stop it in its tracks since we have no clue what still comith this way. 🙁

          • Thanks again, Obewanspeaks. Sorry I didn't thank you yesterday. It was global action day against nuclear energy, and for some reason, my computer wouldn't hitch up to the internet until very late evening. It would happen that day.

            • obewanspeaks obewanspeaks

              As this Nuclear Radiation Contamination Disaster continues to unfold, I expect many millions of computers will mysteriously start to act up all around the globe..

              This is very bad news for the human race.. 🙁

          After a year of searching I just found key to everything Fukushima – where the cores went, the plutonium, why certain reactors online others not. I am sharing this with you because I hope you can pass on as people really listen and THIS must be read:
