| 摘 要： | 高放废物地质处置系统核素迁移研究是高放废物安全处理和处置的重要内容.从整个系统的角度出发,把高放废物地质处置系统核素迁移过程分为三种模式:工程屏障中的释放-扩散模型;地质屏障中的对流-弥散模型和在生物圈中的分区传递模型.在分区传递模型中利用转移系数描述核素在各分区之间的迁移.通过对每种模型核素迁移机理的分析得出概化模型,并给出了相应的数学描述.

| Abstract: | Study of nuclide transport is an important subject in deep geological disposal system of high-level radioactive waste.From the perspective of the whole system,the processes of nuclide transport in deep geological disposal system of high-level radioactive waste are divided into 3 different patterns,including a release-diffusion model in engineering barrier system,an advection-dispersion model in geological barrier system and a compartment-transfer model in biosphere.In the compartment-transfer model,transfer coefficient is used to describe the number of nuclide transport in different compartments.The corresponding mathematic models are also established based on their own conceptual models. |
