Abstract: Fretting wear failure of cladding is the main cause of fuel failure of pressurized water reactor in the world,
thus understanding the fretting wear behavior of fuel cladding in nuclear reactor is very important to the safe operation
of nuclear reactor. The zirconium alloy cladding used in the primary circuit of nuclear fission reactor not only bears the
erosion of high temperature and high pressure coolant, but also faces the harsh environment such as corrosion, strong
irradiation. This paper summarizes the influence of service environment on fretting wear behavior of cladding from the
aspects of mechanical factors, hydraulic conditions, irradiation and corrosion, and expounds the research progress of
accident-tolerant zirconium alloy cladding coating material and its influence on fretting wear between grid to rod fretting
in the future. Finally, the future research direction of fretting wear and corrosion wear of nuclear reactor cladding is
prospected.
Key words: cladding material; accident tolerant fuel cladding coating; irradiation; fretting wear; corrosive wear
