     In order to give our readers an insight into the problems associated with the nuclear disaster at Fukushima;  a little background is required.  Radiation exposure safety levels are not just a function of the intensity of the radiation that a person is exposed to.  It is also a function of the length of time a person was exposed.  Previously we used this analogy.  The person being exposed is like a large sponge in a empty sink.  The water is like the radiation.   A spigot on full force for a brief time will saturate less than a slow steady stream over a much longer time.  Continue reading

As we have discussed here before, The GE Mark 1 BWR (Boiling Water Reactor) has its root in the 1950,s.  Back then the engineers could not have imagined supporting this design in the year 2011.  It is sort of like trying to get a 1955 Chevy to meet all of todays safety and crash standards.  In fact GE has done a remarkable job.  It is also a testament to the sheer robustness of the design.
