Natural analogues for the migration of radioactive elements in granite formations by the study of hydrothermal changes
The document is the final report of the project "Hydrothermal alteration systems as analogues of nuclear waste repositories in granitic rocks", as part of the MIRAGE programme. The data given in this report were obtained from the study of the infilling and hydrothermalised walls of a mineralised vein located in the French Massif Central. A satisfactory model of the processes generated by hydrothermal alteration followed by climatic weathering, such as formation of new minerals, flow of elements and variations in volume, was built. The mobility of elements displaying physical and chemical properties similar to those of radionuclides present in high-level radioactive waste was studied. On the basis of the results obtained, an appraisal was made of the response of a granitic environment which has been disturbed by a hydrothermal system, produced by heat emitted by the storage of high-level radioactive waste, as well as its potential capacities of retention in case of possible leakage.
