Hydrogen Density of Primary Containment Vessel at Reactor No. 2:

  • March 11 @ 0.06%*
  • March 16 @ 0.11%
  • March 22 @ 0.18%
  • March 24 @ 0.25%
  • March 26 @ 0.30%

*Hydrogen density before the recent rise remained relatively consistent for months, ranging between 0.04% and 0.08%

Via Scientific American: The high temperatures that the fuel rods create boil water and continually turn it into steam. If no fresh water is introduced to cool the rods then they continue to heat up. Once the rods reach more than 1200 degrees Celsius, the zirconium will interact with the steam and split the hydrogen from the water. That hydrogen can then be released from the reactor core and containment vessel and, if it accumulates in sufficient quantities—concentrations of 4 percent or more in the air—it can explode, as has apparently occurred at reactors No. 1 and 3, and possibly No. 2 as well.

    Note that the hydrogen levels are currently at .30%, and the danger of explosion occurs at 4%. We still have a long way to go before an explosion, but the data above clearly show that coriums 2 & 3 are still producing hydrogen and thus, are still melting. It also seems logical to assume from this data, that if hydrogen is released at 1200 degrees, and reactor vessel bottom #2 is showing only 49.3 degrees, then the melting corium producing this hydrogen must not be near the temperature gauge. (I know, old argument. This just seems like more data to back it up.)

    Hydrogen levels are likely to actually be a lot higher, as the corium/fuel is already out of the building, but steaming up.. Therefore giving a reading of some sort.. Obviously has tempco very worried, considering there doing further endoscopies,, just when they thought they would find "more" with a longer instrument, peace of mind was denied, there coriums are a roaring menace and with no technology to fix them.

    Can't they just burn the hydrogen off as it's being produced?
    Or at least use some damn engineering controls to collect the explosive gases out of the "PCV".
    That technology does exist…

    It's a shame all the "operator" can do here is look at bogus spreadsheets, produced by bogus data, produced by bogus instruments, produced by bogus sensors, etc etc. I have a feeling these press releases are just buttering us all up for the bogus story that will blame the next massive radiological release (which may have already happened) on a new "hydrogen explosion" that levels the entire complex.

    Then TEPCO will ask the world
    "WHY DIDN'T YOU HELP US?"
    "YOU ALL KNEW WHAT WAS GOING ON HERE"

    The video recorders (TEPCOCAM and TBS) are obviously bogus, edited clips, photo shopped images with video backgrounds, with bogus timestamps edited to the released videos.

    …90 US military..done deal a long time ago…

  • Oh yeah and they were disappointed to find water levels low in #2.

    Somewhere below the complex molten fuel rods are at temperatures above 1200 degrees…. And since the water is leaking out such that the height is only 60 cm…….nothing can really be done, thats why they ain't saying anything…..nothing to do with Japanese stoicism, more to do with greedy idiots who screwed up. Interesting an American company has the contract to clean up…..
    Waiting for Superman or 007 to save the day.

    If Jesus turned water into wine would he come down one last time to turn nuclear waste into flowers? How long will that miracle take?

    • Unfortunately it takes millennia for radioactive waste to turn to flowers…

      He just might. He said "ask and it shall be given, seek and ye shall find, knock and the door shall be opened unto you." He could do it with a word. Or He could provide believing people with the discoveries and ideas for remediation.

      Some truths:
      1) Jesus is the Creator.
      2) Jesus is the Redeemer.
      3) Jesus loves Japanese people with unconditional love.

      Japan as a nation has been very resistant to the Good News. According to one evangelist, Japanese culture makes an idol of relationships, valuing them above truth.

      We are in end times, maybe many Japanese people will be saved as a result of the Fukushima disaster, and thus more Japanese will be saved, because the Bible says there will be people saved out of all nations. This life is not all there is. This world is becoming full of evil and violence, like the Bible says it was before the Flood judgment.

      After the Flood, God reduced man's lifespan to limit all that. So man invented the corporation. And multinational corporations have become the antichrist tool for evil, almost evil incarnate.

      And maybe Jesus will not, maybe this is part of the beginning of the Tribulation. Maybe this is just a foreshadow of Wormwood.

    Truth is, the world's top nuclear scientists can't repair a troubled reactor. It's "so" beyond their capabilities.

      Then they shouldn't be operating.

      Maybe the world's top nuclear scientists can't.

      But I'd bet Joe Blow could put together a robot and arm it with a Brown's Gas flamethrower, and make some serious headway.

      It's such a mess over there, they ought to try this on an actual fuel rod piece.

      If Brown's Gas can treat and neutralize a Cobalt 60 pellet, it could neutralize an extremely radioactive surface or material.

      They've got fuel rods all over the place there, if they haven't tried it yet, they need to get Joe Blow to do it.

        Joe Blow would't repair the place, though. He'd thoroughly dismantle it.

          Apparently, American nuclear industry owners, officials, engineers, and workers are making an idol out of their jobs, and/or their professional reputations, valuing them above truth and what is right. That is, unless this technology is being used secretly right now.

    As Ronald Reagan was fond of saying to his rivals at the debates: "There you go again!" ;-)

    It's ok though… I have no burning historical urge tonight to debunk Ilya Velbov.

    I think they will be using a gas though… Probably pumping in a hellacious amount of nitrogen as you are reading this. Inert nitrogen was one of their remedies of choice last April, but we shall see if they do any good. The proof is in the pudding as my friend Chris in England always says.
