Not sure what you mean about risk not equalling outcome. I can understand the cost argument against nuclear power but the only nuclear accident where there was a significant loss of life was Chernobyl and even those deaths were small in number when compared to numerous mining disasters, oil and gas rig disasters and other industrial accidents related to energy generation. The death toll attributable to Three Mile island and Fukushima were zero. I know the clean up costs of Fukushima are huge but I would count that as part of the rebuild following the tsunami.
