The bonding strength and the residual stresses in HIP clad LEU fuel plate were investigated experimentally. Controlled-bulge tests were conducted to observe and determine the interfacial delamination and the associated energy-release rate between HIP-clad Al and Al, and Al and Zr. Mini-cantilever beams, measuring approximately 700×100×100 microns in dimensions, were used to investigate the fracture behavior of Al-Zr interfaces, as well as pure Al cantilevers. Deformation was carried out in-situ in the SEM, and the load-displacement data was correlated to the observed fracture event. Through-thickness profiles of the longitudinal residual stress were measured with the incremental slitting (crack compliance) method in two clad fuel plates with DU-10Mo elements sandwiched between layers of Al 6061. High-energy synchrotron x-ray diffraction was used to profile the residual stresses in HIP'd plate with 0.1mm resolution in the U-Mo foil. The magnitude and location of the largest stress were determined.
