摘　　要：本文采用Infoworks CS软件对某建筑物地下排水管网中的239PuO2的输运和沉积规律进行了数值模拟。计算出含239PuO2低浓度废水在不同管段中的输运和沉积量以及由总排放口排出的239PuO2总量。239Pu is an extremely toxic group radionuclide. The study on the migratory pattern of Pu has always been a hot topic in the research of radionuclide migratory. In this article, Infoworks CS software is used to conduct numerical simulation on the pattern of Pu migration and sedimentation in the underground drain lines in a certain building. The amount of migration and sedimentation of low-concentration waste water with Pu element in different pipe sections and the gross amount of Pu discharged from the main discharge outlet are calculated and the internal radiation dose, through the drainage channels into the receiving water body, to the public is also estimated.
