A study on flow-induced vibration of fuel rods in a reactor was first reported by Bergreen in 1958. Since then theoretical and experimental researches have been made by many investigators.
This is a review of the studies on vibration of the fuel rod excited by axial flow. The fuel rod vibration is understood to be caused by the self-excited vibration of the rod and the random vibration of the fluid. Some parameters which influence the fuel rod vibration, such as velocity, fluid properties, rod conditions etc. are also discussed.
