Abstract

The groundwater flow in the nearfield of a large diameter hole simulating a deposition hole for spent nuclear fuel has been examined by using a tracer technique. Radioactive bromine 82Br and inactive sodium fluorescein were used as tracers. The observations indicate sparse and narrow flow channels with dispersion caused by diffusion across the velocity profile in the flow channel, or diffusion out of the flow channel. Drilling the large diameter hole has not changed the flow conditions.
