SiC-SiCf composites are being investigated as fuel cladding materials for the next generation light water reactors (LWR) due to their high temperature stability and resistance to irradiation. SiC-SiCf cladding offers excellent safety performance in a loss-of-coolant accident compared to current zirconium-alloy claddings. One challenge in the implementation of this composite for LWR cladding application is the hydrothermal corrosion of SiC at normal reactor operating conditions. In this work, a variety of environmental barrier coatings and coating technologies are being investigated to mitigate the corrosion of SiC. A wide range of coating technologies with candidate coating materials has been developed and evaluated. The near-surface microstructural developments and mechanical properties, and preliminary results of hydrothermal corrosion tests of candidate coating materials will be presented.
