摘要
简要介绍了某极低放填埋场的场址特征、核素迁移预测主要参数的选取和使用的模型,重点介绍了极低放废物填埋场主要放射性核素3 H、90Sr在包气带和含水层的迁移情况,通过对3 H、90Sr的模拟迁移预测分析,基本掌握了3 H、90Sr在特定场址的迁移规律,为场址的安全评价提供了参考。
Based on the brief introduction to the characteristics of the site of a very low level waste landfill,the main parameters selected as well as the model for the prediction of radionuclide migration,this paper focused on the migration of 3 H,90 Sr in both aquifer flow water and flow aeration in the landfill.Through the simulated migration prediction and analysis,the migration pattern of 3 H,90 Sr in a specific site was revealed,which provided the basis for the safety assessment of a site.
