    Well that sucks. They are injecting around 40,000 gallons of water a day into Unit 1 and we can see a sizable portion is boiling into radioactive steam. Then out the top of Unit 1 it blows and rises into the lower winds and the hottest particles make it into the jetstream. The rest of the toxic water flows down into the ground, hits more loose nuclear fuel, gets even more toxic, then flows unimpeded into the Pacific Ocean.

    Soon to hit 600 straight days of nuclear fallout. Imagine what the bioaccumulation for the world will be in 6,000 days (16 years from now).

      I think your injection numbers are too high. Also, they say that they are in a circulation loop now. The question you would need to have answered is "how much additional water are they adding to the loop?" That would tell you how much of the water vapor is being lost to the outside. I haven't seen any mention of adding water to the loop.

    Outstanding video. Some random notes:
    Shows uranium precipitate has coated everything, and is flaking off the steel components.
    Uranium vapors were created during meltdown, and coated every surface inside the Containment when they condensed.
    Explosion may have been from a mixture of zirconium and cesium, as has been discussed previously on ENEnews.
    If they got past the grate into the water, the footage hasn't been released yet.
    Steam may show that water is boiling somewhere.

      Obviously it is still quite hot and the corium just slipped into the ground very rapidly. I'm surprised the grate is still there which I find confusing but perhaps we are only seeing the side of the grate? Excuse my ignorance. Thanks PhilipUpNorth for your analysis which is always insightful.

    Moonshellblue: Begin with the TEPCO drawing, released yesterday:
    Look at the drawing. See the grate level, just above the water level? This is what you are seeing in the video, from the top side of the grate. You can even see the light reflecting off the water in the video. The melted corium fell onto the floor of the Containment, right from the reactor in the middle of the Containment. It missed the grate, which runs around the outside of the Containment.
    Perhaps this blueprint will help, too. You can see the reactor in the middle of the containment.
    More random thoughts:
    The corrosion from salt water isn't as bad as I'd have expected. It looks like the metal will last a bit longer. The blackened steel pipes show evidence of fire.

    Maybe we are looking at oxides of boron? Boric acid disolves in water at high temperatures and we know a lot of the water that was pumped in there was borated. Would it bond to the metal or fuel splatters? I don't know.

    As I didn't get a chance to watch the video yet since today's priority was getting my wife to her last (uggh)radiation therapy treatment session for the stage 3B I.B.C. that she's so far been winning her battle against( πŸ™‚ ) -but from what I've seen and read so far,it looks like the possibility that the #1 corium is closer to the surface than the 100 meters someone else recently "guesstimated" most or all of the molten coriums to be located by now?!! I'm assuming that the findings of the above posted video & summary are a "good" thing-if there's any news or status updates available to date that can be described as "good" that is??!! When reports of low or no temperature readings being displayed to TEPCO had been consistently reported I assumed the corium had left the building and burned it's way back to Hell where it came from,making efforts to contain & clean up the ongoing mess more daunting as a result of not knowing where the molten blobs of crap actually are. So would the steam being present and lack of expected corrosion damage be considered "good" news or at least offer some optimism for those tasked with the job(s) at hand and the rest of us in the "captive" audience of the world stage? Despite being known for my negative outlook for the future of humanity & the planet-I do look for the "light at the end of the tunnel" offering hope??!! Have a great day ALL!! πŸ™‚


      our thoughts of better days go out to you and yours, Johnny Blade…

      Johnny Blade: Your optimism is appreciated, but your normal negative outlook would be more appropriate in light of the evidence in this video. πŸ™
      Note that the steam vapors are very whispy, meaning that the heat source is far away. Note the camera light reflecting off the water below the grate in the video. The water is still. It is not agitated or boiling. Conclusion: There is little corium left in Containment1.
      Where is Corium1? It was perhaps 2,500 F or more when it quickly ate through the concrete and steel base of Containment1, and ate into the fill and mudrock below Building1 in March of 2011. Corium1 has now become Rogue Nuclear Reactor1, a nuclear reactor "contained" by mudrock, a molten nuclear lava which includes the control rods used to shut the chain reactions down, cooled now only by the continuous flow of ground water (which picks up a high radiation load, then exits directly into the Pacific Ocean, which is dying as a result). The inflow of ground water is the only control, so TEPCO has abandoned plans to use wells to lower the water table and build a cofferdam to keep the water from killing the Pacific Ocean Fishery. It will soon be discovered that the Pacific Seafood Industry is a total loss, along with the fishing fleets, factory ships, harbors, and canneries throughout the Pacific Ocean basin. (I won't eat the cesium and other contamination they are selling as Pacific Seafood, will you?)
      And still, there is no coverage of this…

    is it just me or does the gold material look like some sort of fungus or lichen?
