Advanced Gas-cooled Reactor
An Advanced Gas-cooled Reactor (AGR) is a type of nuclear power plant that generates electricity using nuclear reactions. It primarily uses carbon dioxide gas as a coolant to transfer heat from the nuclear core, where uranium fuel undergoes fission. The heat produced turns water into steam, which drives turbines to produce electricity. AGRs operate at higher temperatures for improved efficiency and use graphite as a moderator to slow down neutrons, enhancing the fission process. They are considered a mature, reliable technology, mainly used in the UK, designed to safely produce large amounts of electricity with low emissions.
