WebThese channels contain the nuclear fuel, the reactor control rods and allow the passage of carbon dioxide coolant gas to remove heat from the reactor fuel and core. The main issue associated with graphite bricks is graphite core ageing (weight-loss and cracking). WebA gas-cooled reactor (GCR) is a nuclear reactor that uses graphite as a neutron moderator and a gas ( carbon dioxide or helium in extant designs) as coolant. Although there are many other types of reactor cooled by gas, the terms GCR and to a lesser extent gas cooled reactor are particularly used to refer to this type of reactor.
