【摘要】 利用CALPUFF高斯烟团大气扩散模型,以放射性核素131I为例对大亚湾核电站一旦发生冷端双端断裂事故源项可能出现的大气扩散进行模拟,模拟放射性核素131I在典型气象条件下的空气时间积分浓度和地面沉积浓度分布,可以为核电站事故的环境影响评价方法提供参考。更多还原

【Abstract】 This paper presents the time integrated 131I nuclide concentration in air and deposition concentration on the ground distribution under typical meteorologic conditions.During the calculation,the atmospheric dispersion model CALPUFF model is selected to predict the performance of Daya Bay nuclear power plant under severe accidents.The results can provide reference information for environment consequence assessment in case of nuclear power plant accidents.更多还原
