English Abstract
The National Institute of Public Health and Environmental Protection (RIVM) in The Netherlands is participating in the INTRAVAL project for validation of groundwater transport models, used in safety assessment studies on geological disposal of radioactive wastes. One of the testcases tackled by the RIVM project-team is test-case 8 on the Alligator Rivers Koongarra Ore Deposits. The aim of studying this test-case is to increase confidence in the ability of the METROPOL-code, developed by RIVM, to simulate groundwater flow and radionuclide migration in an inhomogeneous and anisotropic, porous system. Within phase 1 of the INTRAVAL project only a preliminary attempt was made to model the complex situation represented in this test-case. Geohydrological data have been analysed and construction of a three-dimensional geohydrological model of Ore Body 1 has been started. Modelling of the geohydrology of the site and, depending on time and manpower available, also transport of radionuclides as well as geochemical processes will be continued in phase 2 of the INTRAVAL project in close cooperation with the Alligator Rivers Analogue Project.
