WebNuclear 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). WebDec 4, 2024 · Smith explains that MIT’s subcritical graphite pile originally fell into disuse as the nuclear industry quickly shifted from graphite-based reactor designs to alternatives based on light water, heavy water, or liquid sodium. Experiments with the graphite system were thus seen as less relevant.
