滨海核电厂液态流出物间歇排放数值模拟分析

Abstract

Abstract: A numerical model for discharge of liquid effluent from a coastal nuclear power plant is established by using MIKE 21 Hydrodynamic model with transport module in an unstructured grid. Numerical simulations of transport and diffusion of liquid effluent with non-decaying nuclide are carried out with different scenarios of the intermittent discharge starting at the four typical tidal moments respectively, in addition to a comparison with continuous discharge under the condition of equal discharge concentration. The mean concentration distribution, impact areas of liquid effluent in the sea water and characteristic values of intake concentration in different scenarios are given. The comparative analysis indicate that the transport and diffusion process of liquid effluent from the coastal nuclear power plant is mainly affected by tidal current. The intermittent discharge starting at the moment of ebb strength has significant advantages in respect of environmental impact and intake concentration. The calculated results can provide technical support for the optimization of liquid effluent discharge mode and marine environmental impact assessment.

Key words: numerical model, liquid effluent, intermittent discharge, continuous discharge, marine environmental impact
