摘要: 为了计算低、中放固体废物处置场关闭后,放射性核素在孔隙介质中迁移行为以及对公众造成的照射,应用随机数学理论,将处置场岩土体孔隙-裂隙双重介质视为一个随机场,依据流体渗流力学理论基础形成的二维定向渗流理论,建立了反映放射性核素在处置场岩土体中迁移规律的数学模型。结合计算技术,进一步建立可对放射性核素在处置场岩土体中迁移规律进行仿真分析的系统,并可以用于放射性核素在处置场岩土体中迁移规律模拟研究与预测分析,以及对公众所致辐射剂量计算。通过算例重复仿真实验分析,最后进行统计平均得出放射性核素在处置场岩土体中迁移的规律性认识,验证了所建模型是可行的、有效的。

Abstract: Stochastic simulation theories were used to calculate the radionuclide migration in groundwater at low and intermediate level solid radioactive waste(ILRW) disposal facility. To better understand about the dangers of public for radiation and the radionuclide migration in fractured rock masses at low and intermediate level solid radioactive waste disposal, the paper builds two dimensional stochastic seepage grid model to describe radionuclide migration in fractured rock masses, sets up a rigorous computer simulating system to simulate the law of migration in the disposal field of low and intermediate level solid radioactive wastes based on computing technology. Finally, To illustrate the precision and validity of this model that is built into the stochastic mathematical theories and computing technology, the simulation experiments are carried out to understand law of radionuclide migration in the disposal field of low and intermediate level solid radioactive wastes.

Key words: low and intermediate level radioactive waste (ILRW) disposal field, radionuclide migration, stochastic process, porous medium, simulation
