Ziel

PREVIOUS WORK AT UTRECHT HAS SHOWN THAT SMALL AMOUNTS OF INHERENT OR ADDED BRINE CAN STRONGLY INFLUENCE THE LONG-TERM RHEOLOGICAL AND TRANSPORT PROPERTIES OF SALT ROCK VIA PROCESSES SUCH AS FLUID-ASSISTED DIFFUSIONAL CREEP AND RECRYSTALLISATION /1,2/. FLUID-ASSISTED RECRYSTALLISATION HAS ALSO BEEN SHOWN TO BE CAPABLE OF STRONGLY REDUCING ("ANNEALING OUT") RADIATION DAMAGE IN SALT /3/. THE OBJECTIVES OF THE PRESENT PROGRAMME ARE AS FOLLOWED :

1) CHARACTERIZATION OF THE LONG-TERM CONSTITUTIVE BEHAVIOUR OF SALT ROCK, TAKING INTO ACCOUNT SUCH PARAMETERS AS FLUID CONTENT, FLUID PRESSURE, GRAIN SIZE AND CONFINING PRESSURE.

2) FURTHER CHARACTERIZATION OF THE DEPENDENCE OF CREEP-INDUCED DILATANCY AND PERMEABILITY IN SALT ROCK ON PARAMETERS SUCH AS PRESSURE, TEMPERATURE, FLUID PRESSURE, AND DEVIATORIC STRESS.

3) DETERMINATION OF THE TIME-DEPENDENT COMPACTION CREEP AND PERMEABILITY CHARACTERISTICS OF DILATED SALT ROCK, GRANULAR SALT (BACKFILL), AND ANHYDRITE ROCK, UNDER DRY AND WET CONDITIONS. SPECIAL ATTENTION WILL BE GIVEN TO THE DETERMINATION OF AN OPTIMAL (I.E. FAST COMPACTION/RECRYSTALLIZING/SEALING) "RECIPE" FOR GRANULAR SALT BACKFILL.

4) PRELIMINARY DETERMINATION OF THE RATE OF RECRYSTALLISATION (HENCE STORED ENERGY REDUCTION) OF Y-IRRADIATED SALT ROCK AS A FUNCTION OF PARAMETERS SUCH AS SPECIFIC STORED ENERGY, TEMPERATURE, BRINE CONTENT, AND BRINE IMPURITY (FE3+) CONTENT.
