WebHigh-temperature gas-cooled reactors (HTGRs or simply HTRs) are helium-cooled graphite-moderated nuclear fission reactors utilizing fully ceramic fuel (Fig. 2).They are characterized by inherent safety features, excellent fission-product retention in the fuel, and high-temperature operation suitable for the delivery of industrial process heat. Web25 mrt. 2024 · Designs that use a range of different fuel designs, such as solid balls moving through the reactor core like sand, or molten materials flowing through the core; moderators such as graphite; and coolants such as helium, liquid sodium or molten salts. On both counts, the prospects for SMRs are poor. Here’s why. Economics and scale
WebUranium fuel is inserted into the reactor through channels in the graphite core. Control rods, containing boron, are also inserted through other channels to control the reaction and to shut down the reactor. We have around 80 control rods in each reactor but we only need 12 to shut it down. What does graphite do in Advanced Gas-cooled Reactors?
