报告题目: Study of SiC coatings and composites for nuclear fuel applications
报告人：Prof. Ping Xiao, The University of Manchester
报告内容：This talk will be focused on presentation on study of SiC coatings for nuclear fuel particle applications and study of SiC/SiC composites for nuclear fuel cladding. To study the coated particle fuel, the mechanisms controlling the fission product release through SiC coatings has been investigated with use of experimental study and thermodynamic calculation. In addition, the mechanical properties of SiC coatings after high temperature treatment including steam oxidation or proton irradiation have also been investigated. For study of SiC/SiC composites, X-ray tomography has been used to examine the crack propagation of the SiC/SiC composites under mechanical loading, which would help to develop the SiC/SiC composites with enhancement of mechanical properties of the composites.
