INTRAVAL, Test Case 13: Experimental Study of Brine Transport in Porous Media

摘要

Disposal of radioactive waste in geological formations is seriously beingconsidered in a number of countries. An integral part of the safety assessment of nuclear waste disposal is the study of nuclide transport in the geosphere. This requires a profound understanding of the various processes which take place within soil formations; among them groundwater flow. Such studies are commonly made possible by means of mathematical models. Mathematical models serve as a powerful tool for prediction of release of waste into the geosphere, movement of water and contaminants through the geosphere, and calculation of doses of radioactive material reaching the biosphere. Often such predictions need to be made for thousands of years extended into the future. The question then arises how good such predictions are and how much one can trust the results. Answers to such questions are normally sought by the validation of mathematical models. One of the important aspects of validation exercises is the identification of appropriate processes related to the problem under study.
