Because of the stability, corrosion resistance and other good mechanical properties, zirconium and its alloys with niobium have extensive applications in nuclear industry, especially in fuel cladding. In this study, we have considered the micro-structural evolution of this alloy when it is subjected to energetic irradiation. Lattice parameters and other mechanical properties have been calculated and there was a good conformation with experimental results. It has been shown that the maximum damage depth of defect production in this alloy is highly correlated to the direction of irradiation and the average is changed nearly linear with Primary Knocked-on Atom (PKA) energy. Also the collision cascade phenomenon in this alloy has been studied and analyzed to produce defects.
