 Advanced Gas-cooled Reactor

The Advanced Gas-cooled Reactor (AGR) is a type of nuclear reactor developed in the United Kingdom that uses carbon dioxide as a coolant and graphite as a moderator. AGRs were designed to generate electricity by harnessing the heat produced from nuclear fission in uranium fuel. Key features of AGRs include: 1. **Fuel**: AGRs typically use natural uranium dioxide or slightly enriched uranium fuel in the form of ceramic pellets. The fuel is arranged into fuel assemblies.
