摘要
Abstract
The radiation impact of radioactive pollutant dispersion at a representative inland site was evaluated using the CFD numerical simulation method.First,wind tunnel experiments were employed for validation,confirming that CFD simulations can accurately reflect the pollutant distribution characteristics at the site.On this basis,combined with observations from the on-site meteorological station,radiation impact assessments under key wind directions were carried out,and the corresponding radiation dose levels were analyzed.The results show that significant differences exist in radiation dose levels within the plant area under different wind directions.For instance,under NE and N wind directions,the maximum external effective radiation dose to personnel occurs at 460 and 650 m downwind of the stack outlet,whereas the E wind direction corresponds to the lowest radiation level for on-site personnel.It is recommended that additional radiation monitoring facilities be installed in high-dose areas to monitor pollutant concentration and dose variations in real time,and that personnel residence time be controlled to reduce the risk of external exposure.This study can provide a scientific basis for the optimization of radiation protection,personnel safety,and environmental risk assessment at the plant.关键词
