摘要：

A computer code FEFLOW 5.0 was applied for simulating transport of the most mobile radionuclides (H-3, C-14, and I-129) with groundwater from the designed low and intermediate level radioactive waste near-surface repository at Stabatiske site. An analysis of the variability of the model parameters of hydrogeological system such as dispersivity, hydraulic conductivity, porosity, and radionuclide solid/ liquid distribution coefficient (K-d) has been made. The obtained results show that the activity concentration of the most mobile radionuclides in aquifer will remain low for a long time after the repository closure and the conservatively predicted maximal annual effective dose (8.9. 10(-3) mSv/y) to the inhabitant will be much lower than the dose constraint (0.2 mSv/y).
