Cover Story: The high-temperature corrosion of 15-15Ti cladding material in high burn-up situations has been an important topic for lead-cooled Gen-IV reactors. This study aims to examine the simultaneous impact of liquid lead and cesium molybdate on the cladding tube. A capsule was designed and built for exposures between 600 °C and 1000 °C. In order to simulate a cladding breach, a notch design on the cladding tube was introduced. Material thinning by corrosion and leaching at ≥900 °C caused breaches at the notches after 168 h. The temperature-dependent cladding thinning phenomenon was used for kinetic interpretation. As the first of a two-part study, this paper will focus on the capsule performance, including cross-section preparation and preliminary results on the interface chemistry. View this paper
