Graphite as moderator in nuclear reactor
WebJun 1, 2024 · Abstract. Since its first successful use in the CP-1 nuclear reactor in 1942, nuclear graphite has played an important role in nuclear reactors especially the high temperature gas-cooled type (HTGRs) owing to its outstanding comprehensive nuclear properties. As the most promising candidate for generation IV reactors, HTGRs have … WebThe graphite should absorb as few neutrons as possible during the moderating process because neutrons absorbed in any reactor component other than the fuel (parasitic absorption) are lost from the chain reaction. The typical impurities occurring in graphite have a greater propensity for absorbing neutrons than do the carbon atoms.
