      What we can tell from what we all now know, Is a clear indicator to what we could easily infer. It is a good time to start reading between the lines…

      The situation is as I told you earlier. A slinky.

      At this point in time the chain reaction has just started to begin. The fuel has likely metamorphosised into an evenly distributed pile of molten clots, that have all slowly melted its way through the reactors outer containment, through the reactors turbine room, and now finally is penetrating out into the soil of fukushima, through the freshly melted steel and concrete holes, it ruptured in the reactors core and outer containment.

      Though this is a good thing, as the fuel has not all collected into a molten mass the situation. once again, is a slinky. So what can we infer…

      Well I will now explain nuclear mechanics in another simple antidote…

      Nuclear fuel is much like a basket ball, passing through a large spring. and every time the ball makes its way from start to finish, the spring creates four new basket balls, with four new springs, and this process repeats its self, over and over and over… Googles, upon googles of times, instantly. This process, creates heat. Tons of heat… Don’t think of a bic lighter, or a light bulb for that matter… Think of the sun, and how the nuclear reactions, constantly taking place light the planet earth for thousands of millions of years.

      This is the process that humanity took advantage of to create thermal nuclear electricity. By capturing the nuclear fuel in an active coolant. They were able to harness and power, Massive cities globally.

      The problem now, is quite simple… The basketballs and springs (neutrons and atoms), only fulfill that one function. Now that the active…

  • The problem now, is quite simple… The basketballs and springs (neutrons and atoms), only fulfill that one function. Now that the active coolant, is not containing the fuel, the fuel is reacting. And violently! It is doing what its intended to do, create that 500,000 megawatt power source.

    Meaning each molten mass inside the reactors, are literally, vaporizing any coolant, concrete or mass for that matter; into particles of radioactive isotopes by the trillions… While traveling deeper into the planets crust. And in some time will rest at the zone known as the water table.

    The water table will act react with the nuclear fuel like it is bacon, on a frying pan. And the process will release plumes upon, plumes of radioactive steam… This process will last thousands of years, without any intervention. Though once it begins, as stated previously before. Tepco will be “forced to abandon the restoration efforts at fukushima…
    (FYI: If you covered it, it would explode from the pressure collecting inside).

    So that is in short a china syndrome.

    So infer from what I told you all. The releases of steam will get greater, this is because I said: it is now evenly distributed.
    Then I said its a slinky: Meaning what can go wrong will go wrong. (because you cant intervene).
    Once the fuel is all in the water table. It will do what the sun does, react with its self… Violently. We will have a miniature sun resting in a crater, vaporizing trillions upon trillions of particles into the atmosphere, potentially, for thousands of years.
    Well remember those three options I wrote about earlier… Those were after tepco evacuates, and the mess goes all fooey. Those are the events I predict to come, once the situation grows into a 6 reactor event… Maybe someone could reply with a copy of those…

    The analysis, I did is in fact correct. It has had 16,300 views on god like productions, and 400 views on youtube. No one has debunked it. This article also proves it. Its time to face…

      Sorry Tacoma, I don’t mean to downplay the seriousness of the situation but your continued references to the sun (a fusion process) demonstrates that your knowledge of even basic physics is doubtful. These reactors depend on fissile materials to generate heat, the two processes are completely opposite in nature and this oversight on your part indicates a fundamental flaw in your thinking. As such I suspect you should probably refrain from making such dire predictions.

      There is no question this is a serious situation; nobody seems able to predict what percentage of the radioactive material will eventually end up in our ecosystem, or even has already. Unfortunately this is the nature of the beast, there are no experts beyond meltdown, too many variables.

      What everyone should know, and be concerned about, is that even if the process were contained tomorrow, there has already been a significant release of dangerous radioactive particles, some of which may cause us or our children serious harm in the future.

      Physicists, politicians and power company executives will fall over each other to tell us it’s safe. I wonder how responsive they will be when people start getting sick.

            Test ban graphs updated. Another weeks’ data showed up.

            Magenta shows air in Takasak Japan, 200 Km SW of the plant. Blue is Sacramento U.S.

            My interpretation:

            Cesium 137 – Japan
            Ignoring the peaks from explosions/fire (the earliest up to 1000 times or so higher – 3 log x10 divisions) and other events, the current quieter-period air level is lower than before, but not by very much. I suspect that slowly decreasing levels of steam match the drop.

            I believe the May bumps may be from the unit 1 containment degrading, the period when they were changing the injection amount and location, and possible instability in unit 2. The second peak seems to coincide with a temporarily rising unit 2 radiation curve previously showing on the same site as the temp graphs. If there was any fission at all, it didn’t amount to much or last (boron was obtained around that time). Level bumps/peaks were larger for the iodine 131 than for the CS 137.

            The Iodine 131 graph shows a far more striking decrease, with the last level at the Japan site down to about where Sacramento U.S. was May 4th. It’s surprising to me that the difference between those sites isn’t much larger, but the SW Japan site is likely quieter than some others in Japan.

            The Cesium levels show much more drop off with distance, likely due to the particulate form.

            In general seeing the Iodine 131 falling off so significantly compared to the cesium would point to decay and the time since since fission increasing. It falling off even more than decay alone would account for suggests that the steam share from the reactors is falling compared to that from the fuel ponds. Higher reactor water flow relative to falling thermal power would cause more of the heat to be carried away in the water and less as steam.

Also detail us all in on the political ethics being implored in relation to those physics in a way that nobody here would understand? I am afraid it wouldn’t be helpful at all…

As I also pointed out, here and in other posts, not even the physicists seem able to accurately predict the outcome in a meltdown situation due to all the variables.

        The “official” model of the sun as a fusion reactor is seriouly flawed. Alternative theories such as the plasma model or electric model is more valid although incomplete. In short, the sun is an energy conversion device, like any living entity in the universe. It takes in cosmic energy from our galactic center and gives out lower grade energy to the planets. Our earth takes in this energy to sustain the orbital motion, geological and weather activities. Mother earth also takes this energy to make life-supoorting substances.

    Learn about all the types of radiation, and their effects on health. Make backups, on a laptop that is charged. Find information on survival guides, take screen shots. Have a plan. The situation should pan out rather quickly from here. In all of nuclear physics, there is no viable way to counter react the events, to come.

      It is not possible for this process you cite to last for thousands of years. Most nuclear fuel in a power plant is replaced after about five years because its mostly used up and cannot generate sufficient heat anymore.

      So, why do you say this nuclear magma in the ground water will generate plumes for thousands of years?

      • That would be hard to explain why they are cooled for 100+years after they are depleted. Seeing how they are radioactive, and contaminated for thousands of years, and the particles half life will last thousands of years, the fuel its self will last in respect to these figures. Though it may cool sooner than later, its not the point that I am stressing to argue… Though you raise a valid point. I will admit that the fuel will last for a life time which is bad enough to that regard.

          So, the thousands of years comment was not meant to convey an atmospheric plume radiation dispersal vector. Rather, you meant that the ground water will be receiving radiation for thousands of years from the cooled nuclear magma pile. Perhaps you can make this clearer in your write-up the next time you repeat it elsewhere.

      • We know the explosion is possible (as below). I’m looking for references on the self-sustaining nature of a corium-water interation – i.e. will it [or can it] go on forever.

        http://en.wikipedia.org/wiki/Nuclear_meltdown

        At the point at which the corium relocates to the lower plenum, Haskin, et al relate that the possibility exists for an incident called a fuel-coolant interaction (FCI) to substantially stress or breach the primary pressure boundary when the corium relocates to the lower plenum of the reactor pressure vessel (“RPV”).[8] This is because the lower plenum of the RPV may have a substantial quantity of water – the reactor coolant – in it, and, assuming the primary system has not been depressurized, the water will likely be in the liquid phase, and consequently dense, and at a vastly lower temperature than the corium. Since corium is a liquid metal-ceramic eutectic at temperatures of 2,200 to 3,200 K (3,500 to 5,300 °F), its fall into liquid water at 550 to 600 K (530 to 620 °F) may cause an extremely rapid evolution of steam that could cause a sudden extreme overpressure and consequent gross structural failure of the primary system or RPV.[8] Though most modern studies hold that it is physically infeasible, or at least extraordinarily unlikely, Haskin, et al state that that there exists a remote possibility of an extremely violent FCI leading to something referred to as an alpha-mode failure, or the gross failure of the RPV itself, and subsequent ejection of the upper plenum of the RPV as a missile against the inside of the containment, which would likely lead to the failure of the containment and release of the fission products of the core to the outside environment without any substantial decay having taken place.[9]

          Since the RPVs are breached, and at least some of the corium has fallen to the bottom of the pressure vessels (if TEPCO is to be believed), the chances of an explosion like this is slim.

          Something like this in combination with hydrogen may have occurred on March 12/13 to cause the explosions.

          I suspect that the corium has already reached the water table, and the probability of an apocalyptic event like this is very low. Radioactive steam will continue to be produced for several months, though, hence the need to build a sarcophagus like the one in Chernobyl, as soon as possible.

The Admin is trying to make some improvements to the site, and I fully support him. If not abused, it could be a quick way to gauge whether the contribution has relevant value to the overall discussion, or whether or not the majority agree or disagree with the comment. Given that most peeps contributing to the discussions here appear to be reasonable, chances are it may have some value in influencing positive discussion.
