Objetivo

IN ORDER TO ASSESS THE SAFETY ANALYSIS OF AN UNDERGROUND REPOSITORY, WE HAVE TO MODEL THE TRANSPORT OF RADIOELEMENTS IN GROUNDWATER AND THEIR INTERACTIONS WITH THE GEOLOGICAL MEDIUM. SO THE OBJECTIVE OF THIS STUDY IS THE ELABORATION AND EXPERIMENTAL VALIDATION OF THE COUPLING OF A GEOCHEMICAL MODEL WITH A TRANSPORT MODEL OF DISSOLVED ELEMENT.
IN THIS CASE, IT IS NECESSARY TO LINK A WORK OF MATHEMATICAL MODELISATION ON SIMPLE LABORATORY EXPERIMENTS WHERE GEOCHEMICAL PHENOMENA ARE WELL IDENTIFIED; THAT IS THE GOAL OF THE PRESENT STUDY.
Having defined the conditions where a geothermic transfer coupling is necessary, the principles proposed for carrying this out are described. The general STELE model has been constructed from an existing transfer model of METIS and from a speculative model of CHIMERE conceived specifically for coupling and the idea of base compounds.
1. DIMENSIONING OF A LABORATORY EXPERIMENT, ON THE BASIS OF A SIMPLE MODELISATION OF THE TRANSPORT AND GEOCHEMICAL PHENOMENA.

2. FLOW-THROUGH EXPERIMENTS ON CRUSHED LIMESTONE.
2.1 INFLUENCE OF THE VARIATION OF TEMPERATURE OF THE WATER : 40 OR 25 CELSIUS DEGREES.
2.2 INFLUENCE OF THE PRESENCE OF A POLLUTANT LIKE STRONTIUM CHLORURE AT DIFFERENT CONCENTRATIONS.
2.3 INFLUENCE OF THE PREESTABLISHED, EQUILIBRIUM BETWEEN WATER AND CRUSHED LIMESTONE.

3. INTERPRETATION OF THE RESULTS OF THE EXPERIENCES IN THE PERSPECTIVE OF THE MODELISATION DEVELOPED IN ITEM 1.
