Obiettivo TRANSPORT OF RADIONUCLIDES, POSSIBLY RELEASED FROM A SALT DOME REPOSITORY TO THE SURROUNDING AQUIFERS, IS A KEY PROBLEM IN THE SAFETY ANALYSIS OF WASTE DISPOSAL IN SALT. FOR THE NUMERICAL SOLUTION OF THE SET OF EQUATIONS (DARCY'S, FICK'S LAW AND EXTENSIONS OF THESE LAWS FOR HIGH DENSITY BRINES) WHICH DESCRIBE THE TRANSPORT, A FAMILY OF COMPUTER CODES, CALLED METROPOL, HAS BEEN DEVELOPED. SO FAR, METROPOL-1, 2 AND 3 HAVE BEEN DEVELOPED. THEY DEAL, RESPECTIVELY, WITH STEADY STATE 3D FLOW, TRANSIENT 3D FLOW AND TRANSIENT 3D FLOW OF FLUID WITH HIGH DENSITY DIFFERENCES. THE OBJECTIVE OF THE PRESENT CONTRACT IS TO COMPLETE THE DEVELOPMENT OF THE COMPUTER CODE METROPOL-4 WHICH STIMULATES THE TRANSPORT OF LOW CONCENTRATION DISSOLVED SPECIES, INCLUDING SUCH PROCESSES AS ADSORPTION AND DECAY. IN ORDER TO MAKE METROPOL EASILY ACCESSIBLE TO OTHER USERS DOCUMENTATION WILL HAVE TO BE WRITTEN. ALSO FAR AN EASY INTERPRETATION OF CALCULATED RESULTS MUCH EFFORT WILL HAVE TO BE PUT INTO THE DEVELOPMENT OF POST-PROCESSING FACILITIES. 1. INCLUSION OF PHYSICO-CHEMICAL PROCESSES, SUCH AS DISPERSION, DIFFUSION, ADSORPTION, DESORPTION, DECAY, DISSOLUTION/PRECIPITATION OF SALT, CHEMICAL REACTIONS, IN THE METROPOL-CODE. 2. INCLUSION OF THERMAL EFFECTS. 3. CODE DEVELOPMENT. NEW NUMERICAL TECHNIQUES SHOULD BE STUDIED FOR THE SOLVING OF LARGE SETS OF LINEAR EQUATIONS AS WELL AS FOR THE INTEGRATION IN TIME (ADAPTIVE TIME INTEGRATION SCHEME). 4. TESTING AND VALIDATING THE METROPOL-3 CODE FOR THE CASE OF THE FLOW OF HIGH-DENSITY BRINE. 5. PREPARING USER MANUALS FOR METROPOL. 6. DEVELOPMENT OF POST-PROCESSING FACILITIES SUCH AS PARTICLE TRACKING, CONTOUR PLOTTING.
