Abstract

As part of the long-term diffusion project a 780 days long in situ diffusion experiment was performed at the Grimsel Test Site where several radionuclides and inactive iodine were circulated in the packered interval in granodiorite. This paper presents in situ diffusion profiles for tritiated water and iodine acquired from overcored sections of the circulation interval by out-leaching.
