摘要
以我国高放废物地质处置初步概念设计为背景,分析了高放废物地质处置系统中近场核素迁移的基本途径。初步建立了放射性核素近场迁移的概念模型和数学模型,并采用库室模型方法,利用Goldsim通用软件模拟了在参考景象下放射性核素从近场的释放迁移,给出核素从近场的释放率结果。采用日本的概念设计和参数值,利用建立的模型进行了计算,与日本原子能机构JAEA给出的H12报告(使用MESHNOTE程序计算)的结果进行了比较,两者基本吻合。最后提出了需要进一步研究的内容。
Based on the conceptual design for HLW geological disposal in China, the nuclide transport pathways in the near-field of HLW geological disposal system were analyzed. The conceptual model and the mathematical model of the nuclide migration in the near-field were developed using compartment model. The nuclide release calculation under the reference scenario was implemented in current Goldsim software, with which the release rates of nuclides from near-field were then produced. Calculation was also implemented using the models developed and basing upon the concept design and parameters from Japan. The calculation results are consistent with JAEA＇ s. The problems that need further consideration were suggested at last.
