Abstract	Radionuclide migration in crystalline rocks has been studied for many years because these geological systems present suitable properties to host a deep geological repository of radioactive waste. The performance assessment of a repository needs a detailed understanding of the processes that can affect the contaminant transport to bring them in mathematical models adequately. Retention processes occurring in the rock act as the most important safety function of these repositories so they deserve a special attention. In this work, the main retention mechanisms occurring in crystalline rocks will be described, as well as the most common laboratory methodologies to deduce values for the retention parameters. The degree of application to the performance assessment of these concepts and the new tendencies and experimental methodologies to study retention processes will be highlighted. Some examples will be illustrated by experiments carried out by our group at CIEMAT.
