NSUF 24-4892: In-situ irradiation of ZrC and ZrN above 800 C

ZrC and ZrN are promising materials as components in nuclear fuels, like TRISO fuels or surrogate materials for UC and UN, respectively. Therefore, understanding the radiation damage in ZrC and ZrN at their application temperatures is of significance. In the past two decades, the radiation damage of ZrC and ZrN has been performed at intermediate temperatures up to 800oC, which only covers part of their application temperature range. Here, we propose to study the defect generation and evolution in both ZrC and ZrN under Xr or Kr ion irradiation at higher temperatures from 800 to 1200oC. The generation and evolution of gas bubbles and dislocation loops under irradiation at high temperatures will be visualized using in situ transmission electron microscopy (TEM). This rapid turnaround project includes a 2-week in situ TEM observation using the IVEM-Tandem facility at Argonne National Laboratory, experimental data analysis, and a final report, which will take about 9 months in total.
