Keywords: Numerical modelling storm tide particle-tracking entrainment power plant intake
Abstract: The impact of typhoon-induced storm tide on the entrainment at the power plant intake is one of the key issues for the safety of water intake system in coastal nuclear power plants. Evaluation of the entrainment probability at a coastal power plant intake under storm tide has been carried out using numerical modelling in this study. A nested numerical 2D model with a large regional model for storm surge simulation and a local model for simulations of flow and particle transport in the project sea area has been established using MIKE 21 combined with Holland typhoon model. Typhoon Viola have been studied for evaluating the entrainment probability at the power plant intake located in the coast of East China Sea. The transport of particles denoting marine organisms or floating debris in the surrounding sea area of the coastal power plant have been simulated with and without action of the typhoon. The model results indicate that the typhoon generating water level rise causes entrainment probability rise. The entrainment probability of particles from the bay head is much higher than the bay mouth. The maximum typhoon-induced entrainment probability rise is 1.21% during the typhoon period.
