The current multiple crises in climate change and energy supply have shifted attention back to nuclear power as a candidate for baseline energy production in the UK. This course will look at the principles of nuclear power generation, the different types of historic, current and proposed reactors, safety and environmental concerns, the fuel supply chain, the problems of radwaste storage and disposal, the costs, and the role of nuclear in our current and future energy supply. It will be mainly about nuclear fission, but I will touch on nuclear fusion possibilities as well. I studied a bit of nuclear engineering a long time ago but I'm no expert, so this will be a voyage of discovery, and I will welcome the knowledge and expertise of members of the class.
