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

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 accident.

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.”

The situation on the ground at the Fukushima Daiichi plant is so fluid, and the details of what is unfolding are so murky, that it may be days or even weeks before anyone knows how the Mark 1 containment system performed in the face of a devastating combination of natural disasters.

I wear many hats but history, economics and political observance have always been a passion. I am a graduate of the University of Cincinnati College of Business with a degree in Information Systems and Digital Business with a minor in European History. I work for a small mom-and-pop IT consulting and software design company. We deal in servicing mostly government funded non-profit mental and behavioral health care agencies in the state of Ohio. In this I deal with Medicaid and Medicare funds and have a little insight on the boondoggles of government there. Thankfully the undemanding nature of my daily profession gives me ample time to read and stay aware of our current state of affairs which I find stranger than fiction in many instances. In addition to being in the IT field, I have also been self employed with a small contracting company so I might know a thing or two about the plight of small business that employs 71% of the American workforce. I however don't draw my knowledge from my day jobs, which I have had a few; I draw it from an intense obsession with facts and observation about the world in which I live. I do have formal education in things such as history, economics and finance particularly as it pertains to global issues, but I have come to find much of what I thought I knew from the formalities of a state university I had to unlearn through much time and independent research. I hope you enjoy what I bring you which is not often heard in the mainstream news outlets. I would like to think my own personal editorializing is not only edifying but thought provoking while not at all obnoxious. That last one may be a hard to achieve.
