In this study, a hydrodynamic plume model and the best-known k-epsilon two-equation turbulence model of Launder et al. are employed with a computer program, which was developed to solve the unsteady, three-dimensional, coupled partial differential equations of mass, momentum, energy, mass fraction, and turbulent properties. The initial conditions and the relevant boundary conditions of complex topography are supplied by numerical models. The flow fields and the concentrations of the radioactive gases can be obtained in detail. The major focus of this work is on the effects of the complex terrain, in particular the rugged terrain surrounding Kuosheng Nuclear Power Plant. This plant is next to the very populated city of Taipei, and the local topography and surface changes tend to produce considerable distortions in the transport, diffusion, deposition, and accumulation of plume materials. The present study suggests that this model is a candidate for assessing environmental effects and preparing an emergency plan for the future reactor site. Its application to the complex terrain is very successful and provides valuable information.
