| Abstract Scope |
Annular metallic fuel pins offer numerous advantages over solid fuel pin design from the ability to attain high burnups to easier disposal at the end of the fuel cycle. The performance of annular metallic fuels has been an ongoing discussion. High resolution characterization provides vital information in investigating the fuel performance by studying the microstructure and redistribution of elements. Atom probe tomography and transmission electron microscopy offers extensive capabilities in retrieving information at the nanoscale. Both have become a beneficial tool in correlating different factors while understanding the irradiation effects on a material. A prototype annular U-10Zr metallic fuel pin was irradiated in the facility at Idaho National Laboratory (INL) and characterized to elucidate Zr redistribution as well as burnup measurement using isotopic analysis of 235U,236U, 238U and 239 Pu. Such studies provide correlation between fission product distribution and burnup analysis across fuel pin. |
