Creep of Mixed-Oxide Fuel Pellets at High Stress

The rate of steady‐state compressive creep in (U,Pu)O2‐ε was investigated in the power‐law creep region (at a constant stress of 69 MN/m2 between 1600° and 1500°C) as a function of the oxygen‐to‐metal (O/M) ratio (1.88 to 1.995). The creep rate over this range is independent of the starting material...
