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. WebA liquid metal cooled nuclear reactor, or LMR is a type of nuclear reactor where the primary coolant is a liquid metal. Liquid metal cooled reactors were first adapted for breeder reactor power generation. They have also been used to power nuclear submarines .
