摘要

1. The experimental facility enables us to study the thermal creep behavior of the ceramic breeder pebbles, and gives the deformation magnitudes from interaction between the structure and pebble bed at different temperatures. 2. The numerical simulation by DEM using effective Macro-model is able to capture the "trend" of the experimental data concerning thermal creep characteristics, however the absolute values still need to be resolved by finding the correct material properties. 3. According to the numerical results and experimental data, it shows that in a ceramic breeder pebble bed, it is not dominated by a single creep model, the creep model should be determined according to the contact forces.
