Developing a macro-scale SiC-cladding behavior model based on localized mechanical and thermal property evaluation on pre- and post-irradiation SiC-SiC composites

Silicon carbide is being investigated for accident tolerant fuel cladding applications due to its good neutronic performance, high temperature strength, exceptional stability under irradiation, and reduced oxidation compared to Zircaloy under accident conditions. In collaboration with Pete Hosemann (UC-Berkeley), Julie Tucker and Brian Bay (Oregon State), Steve Roberts and David Armstrong (Oxford), and Christian Deck (General Atomics), we are working to develop and improve upon existing small-scale mechanical and thermal characterization methods, including micro-cantilever bend tests and fiber push-out tests, and time-domain thermoreflectance measurements. These techniques will be applied to evaluate micro-scale properties of SiC-SiC composite constituents (matrix, fibers, interphase).
