[…] The outcome of the 70-minute survey into the No. 2 reactor is expected to be announced later in the day. Confirming the state of the melted fuel is likely to be difficult through the investigation, but the utility may be able to gather more information on the reactor’s conditions. […]

the industrial endoscope, 8.5 millimeters in diameter, was to have been inserted into the reactor’s primary container through a hole located about 2.5 meters from the floor of the building housing the reactor.

The fuel inside the Nos. 1 to 3 reactors is believed to have melted through the pressure vessels and been accumulating in the outer primary containers […]

    Well, I am not sure where the fuel is but I think I know which direction to look:


    What are they going to do when they “find” it? Ask it, “Hey, how’s it going? Can you stop that whole melting thing. It’s so upsetting to our shareholders.”

    • BreadAndButter BreadAndButter

      Thanks for the laugh.
      Like someone earlier said, “I need to laugh to not start crying”

      The whole situation is beyond absurd.

        Tepco has anounced rate hikes to cover new cost of generating power. Imo all of the execs should go unpaid. This is the same b. S. they are trying to pull with Vermont Yankee. They say if they close the plant, rates will need to go up. What a crock, i say let the share holders eat the cost of making a bad and risky bet on these old dangerous plants.

          I agree let the shareholders take the hit. Wish I could vote on which way I want my tax dollars spent, I would put it all in wind, solar, geothermal. Wish I had an anti-nuke candidate to vote for also.

        I said that B&B. If I don’t laugh, I’ll just cry. Miss you from back at the FOSL boards!

      loled too!

      This waiting is bad,
      i really wish that they will see the Corium
      and i want to see h3r (him?) too!

    • I think that they will interview the corium and ask it some questions..

      Why are you so upset?

      How much do we have to pay you, to go back inside the reactor?

      Why did you run away from home?

      If this does not work to get the melted corium back into the reactor vessel, maybe they can try threats and intimidation.

    Let’s hope doctors are more proficient with use of the endoscope..when it’s colon screening time.
    TEPCO might want to look up their own behinds….

  • Of course, the fiber optic camera didn’t work due to “radiation”, uh-huh. Like the fiber is affected by radiation, like they didn’t expect radiation.

    Uh-huh, guess the bottom line is that the corium has left the building.

  • farawayfan farawayfan

    So they put the camera in, take a few blurry shots of some pipes and walls, a temp measurement from up high, and job well done! arrrgh.

    Tokyo Electric Power Co. (Tepco) said it had managed to derive some new information from the first images taken by the endoscope in the survey at the Fukushima Daiichi nuclear power plant.

    “The visual artifacts provoked by the high level of radiation and other leaks inside are a viewing obstacle, but nevertheless the images are of relatively good quality in some areas,” Tepco official Junichi Matsumoto said.

    From the story: “The tip of the endoscope is equipped with a 360-degree-view camera and a thermometer to measure the temperature inside the reactor, and possibly the temperature of the water filling the vessel.”

    Do we believe that the vessel is full of water? I’ve lost track of the details, but I had the impression it was breached long ago.

    The article does not hint at the nature of the camera. Anyone know whether it is natural light (how?), infra-red, or some other technology?

    • Unit 2 is the first to have ‘blown’ containment, originally suggested to have been one of the connections between CV and torus. So why didn’t they drill into the torus, if they wanted to follow the corium trail?

  • jackassrig

    If the corium is gone the water is gone unless the water can levitate.

    • Maybe that is what the company told them to do….

      1. Find out where the water levitated to…

      2. Find out where Scottie beamed the melted corium to, on the Starship Enterprise

  • Hey, I am getting thirsty, can you dip me some water from in there?

    Hmmmmm, I do not seem to see any H2O anywhere in the pictures..

    I wonder where it went?

    Maybe Waldo drank it?

    Lots of non information, minutia, and useless trivia..

    Other than the fact that they sound like they don’t know what they are doing, well, well, ok, they got some grainy pictures… full of radiation specks..

    OK, Waldo, now where did you put all of that water and the melted corium? You are in big trouble, mister… Don’t you try to hide from me, mister.

    I see you peeking over the top of the melted corium blob at me.. Now come over here and get your punishment…

    Bad nuclear boy, bad nuclear boy… I am going to have to punish you…

    This is going to hurt me worse than it will hurt you.
