Irradiation-induced growth in Zirconium alloys produced by the anisotropic formation of interstitial and vacancy dislocation loops has primarily been studied in neutron-irradiated reactor core materials, however proton-irradiation offers greater control over the irradiation and environmental parameters. Diffraction Peak Profile Analysis (DPPA) of proton-irradiated Zircaloy-2 samples have been investigated at the Diamond Light Source and the data have been evaluated via whole profile peak broadening analysis using the extended Convolutional Multiple Whole Profile (eCMWP) fitting software. The dislocation loop density has been shown to increase with dose, however the diffraction analysis has revealed the contribution of broad scattering components in the tails of the diffraction peaks. The X-ray diffraction profiles have been compared to computer-simulated patterns of defect containing crystals in order to elucidate the origin of the broad scattering component.
