Failure mechanism of nuclear power pant steam generator tubes inspection crawler gripper petal is analysed in this paper, through macroscopic, chemical composition, metallographic, hardness, scanning electron microscope and energy-spectrum examination, fracture mechanism of the gripper petal is revealed to be brittle rupture. To avoid analogous failure in the future, fatigue test and precautions are presented.
