Abstract Scope Accident tolerant fuel claddings are being developed in order to prevent future accidents like that at Fukushima. In this study, multilayer (TiN, TiAlN) ceramic coating with different compositions deposited on a ZIRLOTM were studied in the Intermediate Voltage Electron Microscopy (IVEM). Preliminary in situ ion irradiation of samples with 1 MeV Kr ions at 300 C and up to 20 dpa on the coatings showed good irradiation resistance of the coatings with the integrity of the coatings remaining after irradiation. No irradiation defects above 1 nm observed during or following irradiation, no obvious change in existing columnar grain structure and size were observed. The ZIRLOTM substrate showed expected defect accumulation under irradiation. Detailed analysis of the ion irradiated samples with different layer architecture and composition will provide a better understanding of the irradiation performance and clearer guidance for further neutron irradiation experiment.
