    Comparative modeling of an in situ diffusion experiment in granite at the Grimsel Test Site

  • Original language description

    An in situ diffusion experiment was performed at the Grimsel Test Site (Switzerland). Several tracers (H-3 as HTO, Na-22(+), Cs-134(+), I-131(-) with stable I- as carrier) were continuously circulated through a packed-off borehole and the decrease in tracer concentrations in the liquid phase was monitored for a period of about 2 years. Subsequently, the borehole section was overcored and the tracer profiles in the rock analyzed (H-3, Na-22(+), Cs-134(+)) H-3 and Na-22(+) showed a similar decrease in activity in the circulation system (slightly larger drop for H-3). The drop in activity for Cs-134(+) was much more pronounced. Transport distances in the rock were about 20 cm for H-3, 10 cm for Na-22(+), and 1 cm for Cs-134(+). The dataset (except for I-131(-) because of complete decay at the end of the experiment) was analyzed with different diffusion-sorption models by different teams (IDAEA-CSIC, UJV-Rez, JAEA) using different codes, with the goal of obtaining effective diffusion coefficients (D-e) and porosity (phi) or rock capacity (alpha) values.
