Low-enriched uranium (LEU) alloyed with 10 wt% molybdenum (U-10Mo) has been identified as a promising alternative to high-enriched uranium (HEU) for the United States High Performance Research Reactors (USHPRR). The nominal configuration of the U-10Mo plate-type fuel is a metallic U-10Mo fuel foil, the thickness of which varies from 0.6 mm (0.025") to 0.2 mm (0.0085") depending on the reactor; a 25 μm thick Zr interlayer–diffusion barrier on either side, and an outer cladding of 6061 aluminum. The aluminum cladding is usually performed using the HIP process. In the present work, the role of interface microstructure and chemistry on the bond strength of Al-6061 alloy bonded by hot isostatic pressing (HIP) was investigated. The impact of different HIP parameters such as temperature, surface preparation, surface texture and strong-back materials on bond strength was investigated. Interface microstructures were characterized to quantify the oxide layer thickness, Mg2Si fraction and interface recrystallization.
