WebJan 1, 2024 · 14.1. Introduction. Along with the use of carbon-coated uranium oxide fuel articles [1], the use of graphite as a moderator for Generation IV reactors is attractive because it allows a reactor core to be designed in a way which, in fault conditions, can reach high enough temperatures to allow the “Doppler effect” [2] to come into play which … WebThe core also has channels for control rods, composed of boron and tipped with graphite, designed to neutralize the reaction. Water flows through the fuel rod channels and the entire structure...
