Study of the performance of geological isolation systems for radioactive waste disposal : Burial in granite formations
As part of the PAGIS project, a study of the performance of geological burial systems for vitrified high level waste in granite was carried out at three sites: Auriat with an efflorescent granite (reference), Barfleur on the Cotentin coast, and a site in the United Kingdom with granite covered by sedimentary rock (other systems). Two types of deposit were studied, with configurations corresponding to two hypotheses: that the waste is cooled for 30 and 100 years prior to storage. The report describes the methodology (including an approach based on cause and effect and one based on chance) and gives the selected basic data and the models used. There was a parametric study of subsystems (rock field, distant field and biosphere) using the AQUARIUS, DIMITRO and BIOS models respectively. The results show the importance of the parameters characteristic of the geosphere and the effects of dilution in surface water. There is also a 3D representation of the run off, which seems indispensable. The report concludes with the results of analysing a human intrusion scenario and a study of uncertainties.
