To study the irradiation responses of U-Mo/Al dispersion fuel, a heavy ion (84 MeV Xe ions) implementation experiment was conducted in the Argonne Tandem Linac Accelerator System (ATLAS) at Argonne National Laboratory. Dispersion fuels fabricated with ZrN-coated fuel particles were irradiated to various doses at ~ 350°C. The highest dose achieved was 2.9×10^17 ions/cm^2 (~ 1200 displacement per atom (dpa)) After the irradiations, specimens of ~10×10×10 μm^3 were sampled from the fuel particles using focused ion beam (FIB), and were characterized using high-energy synchrotron wide-angle scattering at the Advanced Photon Source (APS).
The X-ray beam with the energy of ~62 keV was focused to ~2μm (vertical) by 20μm (horizontal). This focused X-ray was axially scanned from the top to the bottom of the specimens. All the radiation-impacted regions including the Al-U interdiffusion layer, and the Xe bubble concentration area were characterized.
