Technically, there appear to be no show stoppers for a considerable expansion of Nuclear Power throughout the world. It is a low carbon energy source with abundant fuel supplies. The technology works and has much potential for improvement. Whether or not a large scale expansion eventuates depends on how it competes with Coal on economic grounds and with the public on political grounds. This in turn will be determined by the performance of the nuclear industry over the next few years as these purportedly cheaper and safer plants are built.
