A study on the creep characteristics of simulated DUPIC fuel

Creators

Description

Compression creep test was performed using simulated DUPIC fuel in the temperature range from 1773 to 1973 K under the stress range of 21 - 60 MPa. Creep rate and the activation energy were obtained. The activation energy for creep was 649.35 - 675.94 kJ/mol at the low stress region, where creep mechanism was controlled by diffusion. On the other hand, the activation energy at high stress region was 750.68 - 792.18 kJ/mol, where creep mechanism was controlled by dislocation motion. The activation energy for dislocation creep was higher than that for diffusion creep. The activation energy of reference simulated DUPIC fuel was higher than that of UO2
