Abstract Scope Non-oxide uranium fuels such as U3Si2 and UN are being considered for use in accident tolerant cladding because of their high fuel density and superior thermal conductivity. However, it is reported that these fuels have a higher reaction rate with water when the fuel cladding is breached. The high-density fuels are prone to mechanical break-down due to hydride formation during the corrosion reaction. To address this limitation, tests to determine the efficacy of coating pellets with a hydrothermal barrier coating to minimize the degradation of the fuel pellets are being carried out. Several coating options have been investigated including oxidation-resistant glass coatings, ceramic coatings, and metallic coatings. The coatings have been applied to surrogate substrates using methods including dip coating, PVD, and CVD methods. Testing and evaluation of these corrosion barrier coatings will be discussed.
