Abstract

Extensive research and development work is being conducted at different governmental, university and industrial laboratories for developing accident tolerant fuel-cladding systems for light water reactors. Continuous SiC fiber-reinforced SiC matrix (SiC/SiC) composites is one of the candidate materials for replacing the traditional zirconium alloy cladding due to its high temperature stability, chemical inertness and stability under neutron irradiation. A comprehensive database on the statistics of the mechanical properties of SiC/SiC composite is much needed to estimate the failure probability in evolving thermo-mechanical conditions as well as rigorous analysis of the material’s behavior under normal and off-normal reactor conditions. In addition to the properties database, test standards, which ensure the unbiased characterization of the material, are needed. The mechanical properties database, particularly for tubular SiC/SiC specimens, is limited and standardized test methods are still under development.
