As a candidate for accident tolerant fuel (ATF) cladding tubes, chromium (Cr) coated Zry cladding is being developed. In this study, the ion irradiation tests were conducted to investigate the effect of irradiation on Cr layer and interface between Cr layer and Zry substrate. The presentation will discuss the results of these experiments.
