Title: Assessment of Te as a U-Zr fuel additive to mitigate fuel-cladding chemical interactions

Journal Article · · Journal of Nuclear Materials

Tellurium was investigated as a potential additive to metallic fuel (e.g. U-10Zr) to mitigate fuel-cladding chemical interaction (FCCI). A primary cause of FCCI is the lanthanide fission products migrating to the fuel periphery and interacting with cladding, Te therefore was used to bind the lanthanides into stable compounds in the U-10Zr. The present work investigates the microstructures of as-cast and annealed U-10Zr-4Te and U-10Zr-4Te-4Ce alloys (weight percent) with scanning electron microscope and transmission electron microscopy. In conclusion, tellurium was found to bind Ce and form CeTe compound, which will mitigate lanthanides migration to the cladding.
