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 … flowey all facesWebThe reactor core is an array of graphite blocks composed of fuel elements, a control rod guide, and replaceable reflector, which provide neutron moderation and heat transfer, and serves for positioning of control and shielding absorber materials.
