    Fukushima: Mark 1 Nuclear Reactor Design Caused GE Scientist To Quit In Protest


    March 15, 2011
    Thirty-five years ago, Dale G. Bridenbaugh and two
    of his colleagues at General Electric resigned from
    their jobs after becoming increasingly convinced that
    the nuclear reactor design they were reviewing -- the
    Mark 1 -- was so flawed it could lead to a devastating
    Questions persisted for decades about the ability of
    the Mark 1 to handle the immense pressures that
    would result if the reactor lost cooling power, and
    today that design is being put to the ultimate test in
    Japan. Five of the six reactors at the Fukushima
    Daiichi plant, which has been wracked since Friday's
    earthquake with explosions and radiation leaks, are
    Mark 1s.
    "The problems we identified in 1975 were that, in
    doing the design of the containment, they did not
    take into account the dynamic loads that could be
    experienced with a loss of coolant," Bridenbaugh told
    ABC News in an interview. "The impact loads the
    containment would receive by this very rapid release
    of energy could tear the containment apart and create
    an uncontrolled release."
    So there have been concerns about this reactor model for some time.
    "He who does not think himself worth saving from poverty and ignorance by his own efforts, will hardly be thought worth the efforts of anybody else." -- Frederick Douglass, Self-Made Men (1872)

    The state of the art was antiquated compared to what can be designed today.

    The new designs can operate without outside electric power, making them much safer than anything operating today.

    If what they say is true about the new designs I have no problem with building as many as we need to meet current and future needs.

    It seems there is a new power line about to be hooked up going to the Fukushima plants and if so it will end the drams unless one the containment vessels has been breached. I one has been it's going to be tough to fix.
