STUDY OF THE POSSIBILITY OF STORING RADIOACTIVE WASTE IN CRYSTALLIZED TERRAINS. INVESTIGATIONS OF GRANITE FORMATIONS AT GREAT DEPTH
Various and complex scientific problems are raised in many areas by the disposal of radioactive waste in geological formations. Research works are therefore numerous, and are carried out in four basic areas: - improvement of the knowledge of geological media - characterization of their behaviour vis a vis radioactive waste - design of deep repositories - long-term safety assessment of the selected disposal strategies. Aim of the present research is to develop a methodology for investigating granite formations at great depth, in order to characterize their internal structure, and to acquire data about the various physical properties of granite. This research therefore covers the first basic aspect. These goals were obtained by continuous core drilling of two vertical boreholes at 10 m pitch. The main borehole was drilled down to 1003.15 m deep, the second one was stopped at 504.40 m deep.
