Description
Thermal shock behavior was compared among the UO2-5wt%CeO2 pellets doped with various additives (0.1wt% Li2O, SiO2 , Al2O3 and 0.2wt% Cr2O3), sintered in H2 atmosphere at 1700 .deg. C for 6h, in terms of the microstructure characteristics, quenching atmosphere Ar and 93N2+7H2 and temperature difference (ΔT=200∼1400 .deg. C). Vickers hardness was not affected by ΔT and thermal shock atmosphere. Fracture toughness (KIC) of the doped pellets was nearly same as that of none-doped pellet in the ΔT range 200 to 800 .deg. C. The increase of KIC value started at ΔT≥1200 in Ar and at ΔT≥1000 in reducing atmosphere
