Dan from Squirrel Hill's Blog Vermont just replaced its only only nuclear reactor (which had accounted for 71.8% of the state’s electricity production) with fossil fuels obtained from fracking For the past 42 years, Vermont’s only nuclear power plant was responsible for 71.8% of the state’s electricity production. This huge amount of electricity was generated by a single nuclear reactor.Vermont has just shut down this reactor.The replacement energy source for this shut down reactor is shale gas, a fossil fuel whose combustion causes global warming, and which is obtained from fracking.And all this time, I had thought that liberals in Vermont...

The discovery of a new type of fission turns a tenet of nuclear theory on its head. The observation of an unexpected nuclear reaction by an unstable isotope of the element mercury has thrown up a rare puzzle. The enigma is helping theorists to tackle one of the trickiest problems in physics: developing a more complete model of the atomic nucleus. Nuclear fission, the process in which a nucleus heavier than that of iron breaks into pieces, is generally observed to be symmetric, with the resulting fragments being roughly equal in size. Although instances of asymmetric fission are known, they...

U.S. Department of Energy scientists say they've created a computer algorithm that allows a substantially enhanced view of nuclear fission. The Argonne National Laboratory scientists said the algorithm, known as the neutron transport code, enables researchers for the first time to obtain a highly detailed description of a nuclear reactor core. "The code could prove crucial in the development of nuclear reactors that are safe, affordable and environmentally friendly," laboratory officials said in a statement. To model the complex geometry of a reactor core currently requires billions of spatial elements, hundreds of angles and thousands of energy groups -- all...
