Abstract: Pipeline is the main component of nuclear power plants. Pipeline vibration can induce fatigue and fracture of the pipeline. Accumulation of the cracks of the pipeline can cause the power plant to shut down, maintenance, and even catastrophic accidents. In this paper, the main reasons inducing the vibration of the pipeline in nuclear power plants, such as the vibration of rotating equipment, hydraulic hammering action, fluid pulsation, cavitation corrosion, gas liquid two-phase flow, wind, earthquake and artificial error were summarized. Some accident cases and common improvement schemes were introducd. This work may provide some necessary references for pipeline design, construction, maintenance and overhaul in nuclear power plants.
