Irradiation Test HT-31: High Temperature Irradiation Behavior of LASL-Made Extruded Fuel Rods and LASL-Made Coated Particles

摘要

Three LASL-made extruded graphite and coated particle fuel rods have been irradiat¬ed in the Oak Ridge National Laboratory High Fluence Isotope Reactor test HT-31. Test conditions were about 9 × 1021 nvt(E >.18 MeV) at 1250°C. The graphite matrix showed little or no effect of the irradiation. LASL-made ZrC containing coated particles with ZrC coats and ZrC-doped pyrolytic carbon coats showed no observable effects of the irradiation.
