NSUF 14-507: Atom probe tomography of high burn-up mixed oxide fuel
The researchers propose to use atom probe tomography to study the fission product behavior of high burn-up mixed oxide fuel. The primary objectives of the proposed work are to demonstrate the ability to study irradiated oxide fuel utilizing the state of the art atom probe tomography, and utilized this unique first of a kind data to help increase the fundamental understanding of fission product behavior in oxide fuel. Samples will be collected from three radial locations within the fuel pellet. The samples will be analyzed using TEM prior to and after atom probe analysis to ensure the most accurate microstructure reconstructions. This work will provide key insights in the segregation and interaction of fission products with features such as grain boundaries and precipitates as a function of temperature. The proposed work also takes advantage of already irradiated and prepared parent sample available at the electron microscopy laboratory. The proposed work would be completed within 6 months of being awarded.
