摘　　要：ARCON96是目前NRC推荐用于核电站设计基准情况下主控室可居留性评价的大气弥散因子的计算程序。基于国内某核电站厂址实测气象数据,用ARCON96程序对大气弥散因子进行了计算和分析,并将ARCON96计算结果与国内目前采用的组合尾流模式进行了对比。结果表明,ARCON96程序对于主控室可居留性评价中的大气弥散因子计算具有很好的适用性,其计算结果比组合尾流模式略为保守。ARCON96 is the current NRC-recommended atomospheric dispersion model that may be used to estimate atmospheric relative concentration in assessing the habitability of a NPP control room during design basis radiological events.Based on meteorological data from a NPP site in China,the atmospheric relative concentration was calculated and analyzed using ARCON96,and then compared with calculations by the composite wake model.Results demonstrated that ARCON96 is feasible for atmospheric relative concentration estimation and its estimate is more conservative than the composite wake model.
