TWO FIELD PROGRAMMES ARE CONTAINED WITHIN THIS TASK. THEIR OBJECTIVES ARE TO INVESTIGATE MASS TRANSFER IN CLAY-RICH GEOLOGICAL MATERIALS.
THE PRINCIPAL INVESTIGATION IS AT CULHAM LABORATORY, WHERE IT IS PROPOSED THAT WATER FLOW WITHIN THE KIMMERIDGE CLAY IS MEASURED. THE OBJECTIVE IS TO DETERMINE IF STILT-RICH OR CARBONATE-RICH HORIZONS WITHIN THE KIMMERIDGE CLAY ACT TO PROVIDE FAST TRANSPORT PATHS FOR WATER FLOW THROUGH THIS UNIT.
A SUBSIDIARY INVESTIGATION IS TO BE UNDERTAKEN AT SCK/CEN MOL, BELGIUM, WHERE AN IN-SITU MEASUREMENT OF SOLUTE TRANSPORT BY DIFFUSION WILL BE MADE.
CULHAM:
1. GEOLOGICAL CHARACTERISATION OF KIMMERIDGE CLAY UNIT, USING CORES RECOVERED FROM BOREHOLES.
2. DEVELOPMENT OF SUITABLE TECHNIQUES FOR MEASURING WATER FLOW IN THE KIMMERIDGE CLAY.
3. MEASUREMENT OF HYDRAULIC CONDUCTIVITY AT DIFFERENT HORIZONS IN THE KIMMERIDGE CLAY, IN ORDER TO INVESTIGATE POTENTIAL FAST FLOW HORIZONS.
4. COMPARISON OF IN-SITU AND LABORATORY MEASUREMENTS OF HYDRAULIC CONDUCTIVITY.
MOL:
1. DESIGN AND MANUFACTURE OF SUITABLE APPARATUS TO INSTALL IN PORT B, UNDERGROUND RESEARCH LABORATORY.
2. DESIGN AND MANUFACTURE OF AUTOMATED, COMPUTER CONTROLLED COLLIMATED RADIATION DETECTION APPARATUS.
3. INSTALLATION OF APPARATUS IN PORT B, UNDERGROUND RESEARCH LABORATORY.
4. LABORATORY-SCALE TRIAL TESTS TO PROVIDE DATA FOR COMPARISON WITH IN-SITU TEST.
5. IN-SITU TEST TO MEASURE DIFFUSIVITY OF BOOM CLAY USING I-131 TRACER.
