Full carbon accounting for nuclear power
In an interesting report, a team of Australian academics created a life-cycle accounting of carbon dioxide emissions from nuclear plants and found them to be higher than previously thought. The main source of the difference is the mining of uranium, which is predicted to become more energy intensive as the high-grade sources diminish. This report is apparently the first to consider the environmental costs throughout the process of creating nuclear power. It is helpful to have a greater accounting of the impacts of nuclear energy, and this report could be used to further illuminate decisions about new electricity plants. However, I would still imagine that the greenhouse gas emissions of these sources are much lower than any fossil fuel source, even including the transportation and sourcing of the uranium.
