摘　　要：目的基于AERMOD模型机理,研究其在核设施辐射环境影响评价中的应用。方法根据给定的释放源项和厂址气象数据,模拟获取核设施常规运行时气态放射性核素浓度分布,并进一步定性分析气态流出物浓度峰值落地点和时间分布,研究AERMOD模型在核设施辐射环境影响评价中的适用性和应用前景。结果通过AERMOD模型适用性和应用前景分析,得出该模型总体满足核设施气态流出物浓度分布计算需求,可应用于核设施气态流出物扩散趋势和敏感点分析,并可为核设施常规运行的监测计划提供数据支撑。结论本研究可为今后深入开展AERMOD模型在核设施辐射环境影响评价中的应用提供参考。Objective Based on the mechanism of AERMOD model, to study the application of AERMOD in the radiation environmental impact assessment of nuclear facilities. Methods According to the given release source item and site meteorological data, the concentration distribution of gaseous radionuclides during the normal operation of nuclear facilities was simulated, and the location and time distribution of the peak concentration were further qualitatively analyzed to study the applicability and application prospect of AERMOD model in the radiation environmental impact assessment of nuclear facilities. Results Through the analysis of the applicability and application prospect of AERMOD model, it was concluded that AERMOD can meet the needs of calculating the concentration distribution of gaseous effluents from nuclear facilities,can be applied to the analysis of diffusion trend and sensitive points of gaseous effluent from nuclear facilities, and can also provide data support for the monitoring plan of conventional operation of nuclear facilities. Conclusion This research can provide a reference for further developing the application of AERMOD in the radiation environmental impact assessment of nuclear facilities in the future.
