The application of SACTI model in environmental impact forecast of cooling tower in nuclear power plant

The principle and calculation procedures of SACTI model are described. And the environmental impacts from the cooling towers in a nuclear power plant inland are assessed. The results show that visible plume, plume shadowing, solar energy loss, water deposition and salt deposition mainly distribute within a few hundred meters downwind to the study plant site. The adverse environmental effects gradually decrease with the increasing of distance, but the maximum value of salt deposit appears at the distance of 300 m. More research is required to determine evaluation criteria and to improve prediction models to better understand the adverse environmental effects. (authors)
