Scenarios for groundwater flow and radionuclide migration of concern for the TVO-92 safety analysis.

摘要

The project aims at formulating different scenarios relevant to performance assessment of radioactive waste repositories in a crystalline rock formation. The scenarios studied range from a repository located in virgin rock to more complex situations with the potential repository located in the rock but being intersected by fracture zones with different inclinations and strikes relative to the prevailing gradient. The project comprises a study of regional flow and migration systems, and also involves discussions on local scale phenomena such as release from the canisters to the near-field barrier, and phenomena related to the disturbed zone around the repository tunnels.
