| 摘 要： | 应用美国环保局的复杂地形扩散模式(CTDM)预测了我国秦山核电站(QNPP)1,2,3期的空气污染物地面轴线浓度.计算结果与风洞模拟实验测量结果和少量现场监测数据进行了对比.对CTDM理论做了进一步研究,对模式上升分量的计算方法做了一些改进尝试,提出两种修正方案.模式有效性检验表明,修正后模式计算结果更接近风洞实验结果和现场监测数据,计算值与实测值的比值落在1/3.5~3.5范围内的数据百分率分别是:CTDM为54.4%,修正方案1为72.9%,修正方案2为58.6%.另外,文中还做了模式灵敏度分析.

| Abstract: | The Complex Terrain Dispersion Model (CTDM) developed by the American Environmental Protection Agency (EPA) is applied to Qinshan Nuclear Power Plant (QNPP) in China.The ground plume centerline concentrations of atmospheric pollutant in PhaseⅠ,Ⅱ and Ⅲ are calculated.The results are compared with that of wind tunnel experiments and a few field data.Two revising methods for LIFT are put forward.Model reliability test shows that the revising methods are more accurate.The ratios of calculated result to the measurement in the domain of 1/3.5~3.5 are:54.4% in CTDM,72.9% in revision A, 58.6% in revision B.In addition,the model sensitivity is analyzed. |
