Objective
CLAY MATERIAL COULD BE USED AS COMPONENTS OF ENGINEERED BARRIERS PUT IN PLACE BETWEEN HIGH LEVEL WASTE CANISTERS AND HOST ROCK.
THE PURPOSE OF THIS WORK IS TO COMPARE THE BEHAVIOUR OF DIFFERENT TYPES OF MATERIALS, HOMOGENEOUS OR MIXED, SIMULTANEOUSLY SUBMIT TO THERMAL AND HUMIDITY GRADIENT. ONLY THE EARLY STAGE OF THE STORAGE, THE SO CALLED "DRIED STAGE" IS SIMULATED IN THIS WORK.
THE INSTRUMENTAL STUDY REQUIRES AT FIRST THE DESIGN AND CONSTRUCTION OF AN EXPERIMENTAL DEVICE TO REPRODUCE THE ACTUAL PHYSICAL CONDITIONS OF THE WASTE DISPOSAL : TEMPERATURE AND WATER CONTENT.} SUBSEQUENTLY, IN COLLABORATION WITH SCK/CEN, AN IN SITU HEAT TRANSFER EXPERIMENT WILL BE CARRIED OUT IN MOL UNDERGROUND EXPERIMENT FACILITY. AN ELECTRICAL HEATER WILL BE SURROUNDED WITH BUFFER AND BACKFILL MATERIALS. THE WHOLE SYSTEM WILL BE INSTRUMENTED WITH TEMPERATURE, MOISTURE AND PRESSURE SENSORS.THE TEST WILL BE SUPPORTED BY HEAT TRANSFER MODELLING.
B1. RESEARCH AND DEVELOPMENT OF WATER CONTENT SENSORS : - THERMAL SENSOR.
- CAPACITANCE SENSOR.
B2. DESIGN AND CONSTRUCTION OF AN EXPERIMENTAL HEAT TRANSFER DEVICE. EXPERIMENTS AND MODELLING.
B3. PROPERTIES OF BACKFILL MATERIALS, DETERMINED IN THE UNDERGROUND EXPERIMENT FACILITY AT MOL (BELGIUM). IN SITU EXPERIMENTS ON HEAT TRANSFER AND MODELLING.
