| This study compared the neutronic behaviors of the graphite material utilized in standard HTGR reactors to those of yttrium hydride and MgO–BeO moderator materials using the OpenMC and Serpent Monte Carlo codes. keff values for various fuel/moderator ratios in a TRISO particle-embedded moderator matrix were computed. The effect of packing fraction was then investigated, and the keff values for different packing fractions were compared for the MgO–BeO, YH1.85, and C (graphite) moderator matrices in the geometry layout containing randomly placed TRISO particles. In contrast to graphite and MgO–BeO moderators, the keff values for YH1.85 moderator indicated that a very small moderator volume is adequate for thermalization. We also investigated how temperature reactivity feedback impacts different packing fractions. In the temperature reactivity feedback analysis, the overall temperature coefficient was … |
