Abstract

The project Mirage is part of the CEC R&D programme on radioactive waste management. This report presents summary reviews of work done in the four research areas of this project during 1986-7. The first area deals with the chemical behaviour of actinides and fission products in natural aquifer systems. Work has covered complexation with natural and man-made organics, colloid generation in groundwater and retention mechanisms in aquifer systems. The second area involves in-situ migration experiments and the development of measuring techniques. Laboratory simulations and geochemical probes are also reported. The third research area, natural analogues, presents reports on nine projects concerned with radionuclide transport and retardation processes, largely at low temperatures. These relate to diffusion and advection processes in sediments, matrix diffusion and elevated temperature elemental migration in granitic rocks, which are of significance in predicting the behaviour of waste repositories. The last area, calculation tools, reports on the improvement and application of existing models of radionuclide migration, development of models of fracture flow and geochemical speciation, and the CHEMVAL validation exercise.
