    What does this mean?
    What are the implications of a completely melted set of rods?

    In terms of information, you can see they are giving us big doses of reality every day now. Someone decided that it was time to start telling us the truth, but they will do it in pieces and on a time line of their making.

    • Discordian

      What I wonder is, How much worse can it be than this? TEPCO is like BP, they will never tell the true extent of the disaster. They are only releasing the information they feel safe releasing, as horrific as that would be. God only knows what’s really going on.

        I think Obama is totally involved with this crisis. I mean he is informed, interactive, having input and making approvals. Seen like that I suggest he probably approved dumping radioactive waters into the Pacific. Or at least knew about it. Given more time at the wheel, scientifically he is proving to be DEADLY to the environment in his decision making. I can accept mistakes but I can`t accept being treated ignorantly. His refusal to talk about this, following how BP was mishandled, drains me of the huge respect I originally held for him, not as a President, but as a fellow human being. His mark is left and I can`t decide if it is better or worse than Hitler`s.

    Truth? Credibility can be lost only once. It’s unrepairable, although same artists can pop out elswhere redressed and singing new songs.

    When 2 monthts on they admit “total meltdowns” and they knew it, I hear “cores in the soil, we don’t know how deep”. But it’s only little me, shaking head what the …. species we are.

    • Cassie

      Govts and corporations lie all the time to us, regularly and with impunity. They do it for a number of reasons, to cover up wrong doing and incompetence, or with a misguided or perhaps reasonable goal of “protecting the public.”

      In this case, some of us knew the truth from the beginning, we saw the pictures, we saw the looks on the faces of the TEPCO and Govt staff, we read the facts as we had them.

      So we knew the truth. And on this site we are working out the details, and putting the puzzle pieces together the best we can. And following the thread out to logical conclusions. Probably some parallel thought process at top levels of govt. Just nothing they would come out and say.

        You have to remember that Japan was dealing with a massive earthquake and tsunami and then a nuclear disaster. I’m not making excuses for them but they were overwhelmed, to say the least and now they have other countries telling them to prop up their stock when they should be focusing on propping up reactor 4, etc. no pun intended. What a species.

  • Steven

    From what I can gather, the reason there was no real cause for alarm earlier (level 5, remember?) was that no criticality (i.e. meltdown) had occurred, whereas Chernobyl was a LEVEL 7 due to meltdown and MASSIVE RELEASE OF RADIOACTIVE ISOTOPES. Then they raised to level 7, due to multiple reactor ‘issues’, but there was still no real cause for alarm because a couple of ‘hydrogen explosions’ and some ‘contaminated water’ was nowhere near as bad as Chernobyl, which if you recall suffered a MASSIVE RELEASE OF RADIOACTIVE ISOTOPES.

    Here now they appear to be saying that all along, there was at least one and probably three meltdowns, and if you recall, some sort of fire in a (dry) spent fuel pond, some sort of exothermic explosion (black smoke) in another (mox) spent fuel pond which apparently flung bits of plutonium etc all over the show, but don’t worry because at no time has there been or will there be a MASSIVE RELEASE OF RADIOACTIVE ISOTOPES.

    • MountainTop

      There was no nuclear explosion like Chernobyl but still enough released for areas NW of Fukushima NPP to have accumulated contamination in the same orders of magnitude as Chernobyl.

      Depending on where you live, this is a cause of concern. There are readers here who may live in the vicinity of Fukushima NPP, albeit a small number.

      • SteveMT

        This prompts the new age-old question:

        If multiple nuclear reactor core meltdowns occurred simultaneously, but no one could hear them because of a tsunami roaring by, did they make a sound?

  • And it is in the initial two months or less that the radiation release from short lived radionuclides is many orders of magnitude higher than the background! And they can be internal and then dose matters not! No wonder many have been rushed to hospitals. Read the chilling account of Yablokov et al(2009) and see that the fools have not learnt. There is nothing more tragic than ignorance in action. And 2009 to 2011 is two years! Of what use is modern civilisation;s progress? Its corrupt to the cores. We must en masse stop nukes before the chromosomes are altered for many generations elsewhere. The tragedy of it all is we will have to experience several Fukushimas soon- please it is the truth. Just see the terrible effects dams are having on modern civilisation: They are heating up the rocks. melting them and creating great earthquakes. 9 MM quake on March 11 2011 was caused, yes caused by dams of the world.

    • Cassie

      What is the most upsetting is that we were never given instructions as to how to protect ourselves and children. Nothing at all. We were just thrown under the bus.

    • kx

      never heard water dams could do that lol, some link to read pls

    • SteveMT

      Yep, Darth. That post is the frank truth in a sea of TEPCO lies and those lies were enabled by other world governments who knew the truth from the outset.

  • Don’t ‘they’ call us “useless eaters”?

  • tony wilson

    forget the daily tepco bullshit of old news,they knew meltdown had begun within 5 hours of the earthquake.christospher busby was saying a meltdown had happened within a couple of days.
    what it means is not so much a china syndrome but certainly a movement of core magma downwards.
    a super hot entity that is self sustaining.
    as the core goes down massive radiation release upwards. probably happening in 2 or 3 buildings.
    apart from the never ending release 2 immediate issues need to be addressed.
    how far down is the water table calculations need to be done because when 3 cores hit the water table it will be the biggest bomb in history.
    calculations done at chernobyl suggested that if that 1 smaller reactor core hit the water table,it would destroy minsk 300km away and render europe a wasteland.
    the other issue is 3 super heated reactor cores
    effect on seimic activity as they work down through shifting tectonic plates.
    christopher busby nailed it when he said this was like a bad science fiction movie.
    even jg ballard never came up with this story line and what an ending japan sinks the earth dies.

      “because when 3 cores hit the water table it will be the biggest bomb in history.
      calculations done at chernobyl suggested that if that 1 smaller reactor core hit the water table,it would destroy minsk 300km away and render europe a wasteland.”

      This can not be true. We’d have a steam explosion and a massive release of radioactive isotopes. Only a relatively small explosion. Nevertheless dangerous of course.

      “the other issue is 3 super heated reactor cores effect on seimic activity as they work down through shifting tectonic plates.”

      There won’t be any effect. The cores would never dive this deep into earth and even if they would, they are far to small and weak to trigger anything in tectonical dimensions.

      Don’t get me wrong. We have a deadly catastrophe, but we really should not start telling wierd things.

        Amen to that.

      • tony wilson

        japan is sinking the fukishima site is built next to a massive caldera.
        3 self sustaining melting reactors,your cracked just like the tectonic plate.

        please watch this start at 4.30..
        i think i will believe a russian nuclear physicist.

        • Anthony

          So if Japan is not responding in kind one can assume they have given up averting the outcome? The outcome demonstrated via Chernobyl is intensely a more minor example of the Fukushima potentials, isn’t it? I would think one mega-explosion would trigger other mega-explosions right? What if they don’t stop detonating?

      • Steven

        My understanding (correct me if I’m wrong) is that sudden criticality could occur due to the molten mass being at the centre of a steam explosion (as it penetrates the base concrete) which would then super-compress the radioactive fuel into sudden close proximity, much as the segmented conventional explosive charges function in a nuclear weapon. Again as I understand it, this is a risk not a certainty, but then there are three dice rolling…..

    • Deetu 3

      Correct me if I’m wrong ,but the danger of an epic explosion at the chernobyl accident was from the molten fuel encountering water IN THE BASEMENT OF THE BUILDING,not the water table.Two workers sacrificed their lives to facilitate removal.If reports are to be believed,there is currently 3.000 tons of water sitting in the basement of reactor building1. Either the completely melted fuel load is still in the containment,(no 3 megaton explosion so far) or the building layout is a fortunate one…anybody?

  • mark V

    The Japanese government has revealed it had to learn key developments about the crisis at the Fukushima nuclear plant through media reports… – ABC Radio Australia, just in.

    Oh yeah, carrier-pigeons had all been sent to request escorts, but luckily morning papers arrived in time.

  • mark V

    p.s. I would be very worried, if these Great Leaders got to hold a pen – could swallow and choke.

  • Buck-O

    Take this new information with a grain of salt. TEPCO has proven themselves liars since the beginning. They have lost all trust by the people of Japan.

    • Anthony

      Good because if Japanese citizens address TEPCO`s existence it would be more effective and appropriate than the world`s citizens having to rumble.

  • Re tony wilson’s comment, Nuclear Engineering International had reported that after the Three Mile Island catastrophe at 428 AM on 28 March 1979, by 8 30 AM the same day 53% of the core had melted away. Thats 4 hrs. So the estimates of full core melting in the worst case would be about 8 hrs or so. I remember that in the Sci Am way back in 1982 or so while discussing Pebble Bed Reactors, the full core would begin melting 65 minutes into the loss of cooling….

  • Steven

    NHK reports “The US Nuclear Regulatory Commission says it has halted 24-hour monitoring of Japan’s Fukushima Daiichi nuclear power plant as conditions are slowly stabilizing there.”

    see for full report.

    With the Chernobyl meltdown they apparently scrambled to pump the water out from under the containment vessel and reinforce the concrete base, to avoid a possible 3 to 5 megaton explosion, presumably due to the resultant steam explosion triggering criticality if/when the molten fuel reached the water.

    At Fukushima however, just after discovering one and possibly three meltdowns, they send the night shift home and claim it’s stable. Perhaps there’s something I’m not aware of…. any ideas?

    We must NOT allow another “shock and awe” session to go on without..something productive coming out of it.
    Write, call, email….the MSM,government agencies, etc.
    Truly be active.
    Do not be deterred by the lack of response.
    Pick one like the NYT.
    Swamp them.
    Call Rolling Stone..ask them what the HELL.
    Tear into FOX news.
    The treasonous ways of CNN?..well..the people will have their say through time.
    Strenghten your heart with words of patriotism.

    • oh yeah!

      Even if you don’t get the results you want right away, you will KNOW that you did what you could. We need to do more than whimper!!!
      To do nothing now amounts to committing suicide. Keep fighting!!! Make it public knowledge!!!

  • Heart of the Rose

    “we do not have to be uniformed to be unified”

  • Darth

    Dear Heart of the Rose,

    It is too late for activism. Too much water has gone under the bridge. We are headed into catastrophe that cannot be avoided.

    If the steam bomb goes off in Japan when the cores reach the water table it means all HELL has broken loose. The radioactive fallout will be equivalent to have set off 2,000 nuclear bombs in the atmosphere.

    BTW – how does one “quote” on this forum?

    • Deetu 3

      My thoughts also.too much water has gone under the reactors.
      -quote by copy n paste then add the little decorations according to taste.

    • oh yeah!

      Complacency is what put us in this situation. I think we need to make this crisis public knowledge, at the least!!!! and then force the hand of complicit government…
      It’s not going to be a quick “lights out” for any of us. We still must take responsibility & ACTION to improve the situation for the history books, if nothing more, but I’m sure there will be more!…

  • Heart of the Rose may be too ….but it behooves one to die free….

    • oh yeah!

      I’m with Heart. Go down fighting with all you got and take these insipid, greedy morons down w/ ya!

    Dear all,
    I recently discovered this website (and subsequently fairwinds associates), I am truly amazed to find constantly up-to-date information, this was clearly something I was missing. Thank you all for the unvaluable comments. As a french speaker, I can tell you that french speaking sources of information on Fukushima are even more scarce than english ones, this is frightening that everything goes hidden from most of the people (“Fukushima? It’s done, no?”). I am surprised to read that melted cores, if doing their way up to the water table, can produce a gigantic explosion due to steam production. Anyone has any link about such an hypothesis?

  • youb

    @Jeremie : il y a -en français- le blog de Paul Jorion qui via le travail de François Leclerc a été pour moi une source d’information fiable et de réflexion inestimable sur le sujet (et ceci dès le début de la catastrophe ou presque)… des commentateurs “éclairés” y ont très vite remis en question la “communication” de TEPCO et certains ont apporté des contributions extrêmement secourables aux “nuls en nucléaire” , leur permettant ainsi de saisir au mieu la situation.

    After that smoke was seen coming from them the site showing where the plume would go was taken off line.

    I’m afraid we are in the final throws of china syndrome times the number of fuel rods, in or out of containment will be a Moot Issue once one goes the area will be too hot to work in.
    Listen to Dr. Kaku and wonder why these things were ever let to be in the first place?

    Arnie Gundersen on May 13th}

    Gundersen says Fukushima’s gaseous and liquid releases continue unabated. With a meltdown at Unit 1, Unit 4 leaning and facing possible collapse, several units contaminating ground water, and area school children outside the exclusion zone receiving adult occupational radiation doses, the situation continues to worsen. TEPCO needs a cohesive plan and international support to protect against world-wide contamination
