Safety Requirements of an Advanced Gas Reactor - Nucleus
WebA gas cooled reactor was first developed in the U.K. which uses CO2 as a coolant instead of water and graphite as a moderator. It is also called a Gas Cooled Graphite Moderated (GCGM) reactor. The basic diagram of the gas-cooled reactor power plant is shown in the figure, Gas Cooled Reactor Power Plant It uses natural uranium as fuel. WebJan 5, 2024 · The reactor core is made of graphite and filled with 15.5% enriched fuel pebbles. Each pebble (roughly the size of a billiard ball) contains thousands of specially coated Tristructural Isotropic (TRISO) … WebAbstract Nuclear graphite has been used as a moderator material in nuclear reactor designs dating back to the first reactor to reach criticality, Chicago Pile 1, in 1942. In addition, it is anticipated to be used in the conceptual Generation four (GenIV) Molten-salt reactors (MSRs) and the High-temperature gas-cooled reactors (HTRs). othmar frei
