Mr. Yastel Yamada, a retired engineer and founder of the Fukushima Skilled Veterans Corps: Now this is a simulation carried out by Tepco of what happened in the vessel…

In the case of Fukushima, the fuel has melted down and eroded the concrete. And now Tepco says that there is some room. And they say this depth is 65 centimeters, 25 inches, but this is a simulation. No one has seen inside. Therefore, the shape of the debris is not known. This is just an assumption. And temperature is measured say 4-5 points, but the reliability of the measured temperature is very bad because of the damage inside. And furthermore sand and concrete is not uniform material like steel. It’s a mixture of stone, stand and cement.

Therefore that 65 centimeters must have, say 100 percent error, then if so the vessel bottom might be eroded, or broken.

    Breaking! Okinawa police remove anti-Osprey protesters, dismantle barricades

    Local residents, who are outraged by Monday’s deployment of the aircraft, began barricading one of the base’s gates last Thursday. Over the weekend they were parking their cars near the other two gates as well, effectively stopping all traffic from entering or leaving.

    Okinawa residents are worried the aircraft’s safety is not up to standard as the MV-22 has a troubled history of crashes.
    [...]

    Aircraft will be prohibited from flying over nuclear power plants

    What?! Tepco, 100% wrong. That can't be right.

    Nuclear plant construction to resume in Japan

    A Japanese power company says it will resume the construction of a nuclear power plant. This is the first such move in the country since last year's nuclear accident at Fukushima.

    President Masayoshi Kitamura of the Electric Power Development Company, or J-Power, announced the decision on the Ohma plant in Aomori Prefecture on Monday.

    Kitamura told a special session of the Ohma town assembly that his company decided to restart the project because of the government's recent clarification of its stance on uncompleted nuclear plants.

    The assembly members welcomed the decision.

    J-Power also dispatched officials to Hakodate City in Hokkaido to explain the decision. The city is located about 20 kilometers from the plant and is against the project.

    Hakodate Mayor Toshiki Kudo told the officials that his city will never accept the decision, because the Ohma project received government approval based on criteria set before the Fukushima accident.

    Kudo told reporters that the city will take legal action to stop the project.

    J-Power began building the plant in 2008 but stopped after the Fukushima accident. The facility is nearly 40 percent complete.

    "This is just an assumption." The only melted fuel still inside containment in Units1,2,&3 is a thin layer of residual corium with an inch or two of water flowing over it. There is a big hole in the bottom of the containment, and through the basement floor. There is a tunnel through many feet of mudrock under the buildings to three 65-100 ton globs of melted fuel, which have become Rogue Neclear Reactors.

      Just dump a bunch of Corexit down the hole. That stuff makes *any* problem (or at least the pesky observers) disappear.

      They should also put an ad in the Argentinian newspapers: "LOST: One or more several hundred ton blobs of glowing, smoking corium lost in Japan. Should eventually be surfacing in this area. Reward for return (your choice: Chiba Mushrooms or Bluefin Tuna)

      If corium found, do not eat, use for light source or sell on eBay. Please call TEPCO immediately.

      Please do not contact Westinghouse, GE or Hitachi. The reactor is no longer covered under manufacturers' 1-year parts and labor warranty.

    Look a those high-quality containments.
    They withstand a hydrogen explosion and a core-melt,
    but this damn seawater…
