Debate

High Temperature Gas-Cooled Reactors

Contribution

My Lords, our much vaunted nuclear revival is based on the deployment of pressurised light-water reactors. These are grossly inefficient in their use of uranium fuels, which will be in short supply within a decade. They will need to be replaced by safer and more efficient reactors, such as thorium reactors and fast-neutron reactors that breed their own fuels. However, within the past 12 months we have seen the departure from the UK or the closure of projects aimed at developing such reactors. Are there any remaining prospects of developing advanced reactors in the UK, or will we be dependent in future on foreign technologies based on technologies pioneered in the UK?
