Abstract Scope |
For a systematic understanding of the dependence of radiation tolerance on specific energy loss, yttria stabilized zirconia (YSZ) with different grain sizes (tens of nano-meters to few microns) were irradiated under different conditions (single beam irradiation with high energy (Se>>Sn) ions at 300 K and 1000 K, single beam irradiation with low energy (Sn>>Se) ions at 300 K & simultaneous dual beam irradiation with high and low energy ions at 300 K). The low and high energy ions were chosen to mimic the damage produced by alpha recoils and fission fragments respectively, and thus the irradiations at 1000 K and the dual beam irradiations helped to better simulate typical nuclear reactor environment. The damage for all grain sizes was found to be reduced at 1000 K. This damage reduction was significantly more for the nano-crystalline samples. Results are explained in the framework of thermal spike model.
