Advanced Gas-cooled Reactor (AGR)

An Advanced Gas-cooled Reactor (AGR) is a type of nuclear power plant that generates electricity using nuclear fission. It relies on carbon dioxide gas as a coolant to transfer heat from uranium fuel to produce steam, which drives turbines. AGRs use graphite as a moderator to slow down neutrons, enhancing the fission process. They operate at higher temperatures than earlier reactors, improving efficiency. AGRs are primarily used in the UK, offering a reliable, low-carbon energy source while maintaining safety through multiple containment and safety systems.
