WebThe VHTR is a helium-gas-cooled, graphite-moderated, thermal-neutron-spectrum reactor with a core outlet temperature > 900°C, and a goal of 1000°C, sufficient to support high-temperature processes such as production of hydrogen through thermochemical processes. WebAnother potential issue with using graphite as a moderator is its ability to oxidize in the presence of air, and its low strength and density which could cause it to change dimensions in the reactor. Reactors that use … WebJan 23, 2024 · The Chernobyl reactor used a graphite moderator and water coolant without a containment structure. Although some of the design flaws were corrected after this accident, RMBKs are considered to be the most dangerous reactors.
