WHY NUCLEAR POWER CANNOT BE A MAJOR ENERGY SOURCE

It takes a lot of fossil energy to mine uranium, and then to extract and prepare the right isotope for use in a nuclear reactor. It takes even more fossil energy to build the reactor, and, when its life is over, to decommission it and look after its radioactive waste.

As a result, with current technology, there is only a limited amount of uranium ore in the world that is rich enough to allow more energy to be produced by the whole nuclear process than the process itself consumes. This amount of ore might be enough to supply the world's total current electricity demand for about six years.

Moreover, because of the amount of fossil fuel and fluorine used in the enrichment process, significant quantities of greenhouse gases are released. As a result, nuclear energy is by no means a 'climate-friendly' technology.

This excellent, and extensive article, discusses the reason's why nuclear energy, will only provide a small supplement worldwide, to the losses that will occur with hydrocarbon and gas depletion.
