铀在花岗岩介质中的迁移预测
Prediction of uranium migration in granite media
摘要
Abstract
Choosing a preselected high level radioactive waste disposal site as study area, a hydrogeo-logic migration function is constructed. Several hydrogeologic parameters such as vertical dispersity, diffusion coefficient, flow velocity, simulated groundwater concentrations are discussed,and distribution coefficient of granites particles in the study area was measured by using batch method. Meanwhile the conditions after the uranium entered into the groundwater were simulated and predicted by using American hydrologic modeling software PHREEQC- Ⅱ.The different roles of the various influential factors such as the pH values, dispersity and diffusion coefficient in the simulation are analyzed. The results show that pH values, dispersity and diffusion coefficient have an important influence on the nuclide migration in the groundwater of study area.关键词
