Abstract Scope |
This study aims to investigate the mechanical and corrosion behavior of Accident Tolerant Fuel (ATF) claddings under conditions simulating light water reactors (LWRs). This research focuses on understanding the impact of intentional coating defects on hydrothermal corrosion and mechanical properties. The group utilized a novel mandrel loading setup for in-situ stress application on tubular samples with induced coating defects at high-stress areas in the autoclave. Data collected through Linear Variable Differential Transformer (LVDT) were used to construct stress-strain curves, while Transmission Electron Microscopy (TEM) was employed for coating-substrate interface characterization. The findings from this study will provide critical insights into the performance and safety implications of ATF cladding materials within LWRs. |
