[Abstract]:The foggy plume diffusion of mechanical ventilation cooling tower is an important issue in environmental impact assessment of important plant water system in inland nuclear power plant. The atmospheric environment near the mechanical ventilation cooling tower of the nuclear power plant is directly affected. Taking the inland nuclear power plant sites of Pengze and Jingyu in Jiangxi Province as the research object, the environmental impact assessment model of the cooling tower SACTI is used to simulate and predict the different sites. The characteristics of spray plume diffusion of mechanical ventilation cooling tower under different cooling tower design and different layout scenarios were determined to determine the environmental characteristics of different plant sites and the possible influence of cooling tower design on the spray plume diffusion of mechanical ventilation cooling tower. In different design scenarios of mechanical ventilation cooling tower, the influence range of foggy plume diffusion environment caused by one machine's four towers is wider than that of one machine's two towers, and the length range of fog plume is about 2.1 times that of the former. The range of fog plume height is about 1.3 times of that of the former. Under different cooling tower layout scenarios, the linear arrangement and parallel arrangement in one and two tower scenarios mainly affect the distribution of the length of fog plume and the height of fog plume in the near field. Under one and four tower scenarios, two kinds of arrangement schemes mainly affect the distribution of far field fog plume length and low site fog plume height. Under different plant site scenarios, the difference of fog plume diffusion between one tower and two tower schemes is the greatest. The difference of foggy plume diffusion between two plant sites is the least.
