Analysis of heat treatment effect on fretting fatigue occurrence in Zr-1Nb-1Sn-0.1Fe fuel rods

Nuclear fuel rods prevent the loss of nuclear material to the refrigerant fluid, acting as a first safety barrier. Damage by grid-to-rod fretting remains a significant cause of nuclear fuel element failure in Pressurized Water Reactors (PWR). In this paper fretting-induced friction at the contact in...
