The aim of this contract was to build and use an experimental drilling probe, the AUTOLAB probe, to measure the diffusion into clay of radioactive pollutants originating from a high activity waste storage. The measurement was carried out in situ during drilling. The probe is equipped with a new operating mode which involves using the pressure of the drilling water as its source of energy. The probe is autonomous and can stay in the bore hole for an extensive period of time without requiring any monitoring and without introducing any pollution.
