The performance of metallic fuel in a fast reactor is known to be depended on several factors including fuel composition, microstructural changes in fuels, fission products distribution, and fuel-cladding chemical interactions (FCCI). Study on evolution of microstructural changes in FCCI layer is highly desirable for a greater phenomenological understanding of FCCI and fuel constituent redistribution. To that end, we investigated HT-9 cladding on U-10Zr fuel subjected to a local burnup of 5.7 atom percent and a local inner cladding temperature of 615 °C. Atom Probe Tomography (APT) and Transmission Electron Microscopy (TEM) is employed to investigate the distribution of fission products and microstructural changes in HT-9. Specimens for TEM and APT were prepared from different part of FCCI to elucidate chemical distribution of fission products and microchemical changes in HT-9.
