The gas-cooled fast reactor (GFR) system is a nuclear reactor design which is currently in development. Classed as a Generation IV reactor, it features a fast-neutron spectrum and closed fuel cycle for efficient conversion of fertile uranium and management of actinides. The reference reactor design is a … See more Fast reactors were originally designed to be primarily breeder reactors. This was because of a view at the time of their conception that there was an imminent shortage of uranium fuel for existing reactors. The … See more In a GFR reactor design, the unit operates on fast neutrons; no moderator is needed to slow neutrons down. This means that, apart from nuclear … See more Past pilot and demonstration projects have all used thermal designs with graphite moderators. As such, no true gas-cooled fast reactor design has ever been brought to criticality. The … See more • IAEA Fast Reactors and Accelerator Driven Systems Knowledge Base • INL GFR workshop summary See more The gas used can be many different types, including carbon dioxide or helium. It must be composed of elements with low neutron capture cross sections to prevent positive void coefficient See more • Energy Multiplier Module • Fast breeder reactor • Fast neutron reactor See more WebGas Cooled Fast Reactor (GFR) A mixture of depleted uranium and about 15%—20% plutonium is the fuel for this type of reactor. It is a pin or plate-based fuel with circulating helium. The peak temperature is about 850 °C. There is no breeding envelope: plutonium is produced by neutron capture directly inside the fuel (fast unmoderated ... 馬 ブレワイ
