  • Simulation of melt-through
  • Experts simulation suggests melted nuclear fuel penetrated the bottom of the reactor at 8:15p on March 14
  • Destruction of the containment vessel was becoming increasingly likely


  • Workers: Radiation at 29 sieverts


  • “The unimaginable was happening”


  • Unidentified Tepco Employee: I thought the situation could end up ruining the whole country


  • All the workers could do was repeat their fruitless efforts to vent the reactor


  • Alarming and no good news…
  • Unidentified Tepco Employee: Total despair
  • Then at 6a March 15, an explosion
  • Check drywell and suppression chambers
  • What’s the pressure?
  • ZERO
  • Front line workers thought part of the containment vessel had been destroyed
  • “We heard a loud bang”


  • What happened? “No one seems to know”

    … that was, when they said to the public: "Everything is under control and no radiation was released so far", right? (Just wanted to mention…) -.-

    Reactors get out of control, as proven by past and present disasters. We need to abandon this failed technology.

    It's a disgrace for the higher powers to sit their and not inform the people, if you can not trust your government to protect you, what is democracy a dream.
    Well let me tell you things are changing, through this Internet we will dispose you.
    I think the government should give everyone a tablet for free and once a week they have to log on and vote on issues, we don't need these leeches on society.
    Our combined knowledge will overwhelm them.
    Power to the people, peace and tranquility, as a collective we have a say.

    Well over a year ago, given how much water was pouring back out of Reactor 2 after it was sprayed in, Arnie Gunderson had estimated that there was a hole in the containment vessel of Reactor 2 about the size of a small house.

    High pressure reading->Bang!->zero pressure. If Newton can reason his way through physics, and Einstein can reason his way through relativity, we need to reason our way out of this failed technology. At least one of these machines fail every 10 years. That is unacceptable.

    One of the interesting points of the video is that the drywell pressure was also very high. Although not stated, that had to mean that the primary containment was already breached. The drywell is the secondary containment, and there is no reason for the pressure to be similar to the primary containment unless there was a large hole. Another clue was the 29 sievert reading inside the drywell, which could only happen with a pressure vessel or main cooling line rupture. Did anyone consider venting the drywell, which has openings and penetrations?
    Another point is that apparently the plant had many of it'd sensors operating. Any time that Tepco claims that they do not know what was happening in any of the plants that is just bullshit. They knew exactly what was going on.
    The explanation at the end of the video about the 12 volt battery fiasco show how incompetent Tepco actually was. After they lost main power the most important need was for more batteries, and they had a stack of them just down the road. But they were not delivered because no one was prioritizing needs. Which just proves that a large part of the problem was probably avoidable if not for human error.

    • Surely one little Honda generator to power 5 KW have been possible … possibly the rectifier.

      able to borrow from the gas station, or from the hypermarket….

    They couldn't stop the meltdowns, and they had no clue which way the plumes were going, as proven by them sending people into the plumes. The giant radiation plumes go where they go. And we only find out after it's too late. Chernobyl, Fukushima …radiation spreads (completely uncontrolled) around the world. The next will be the same, because that's the danger we risk with nuclear power, (risk and loose).
