New methods and approaches to studying the permeability of crystalline rocks based on physical and numerical experiments are considered along with the results obtained by them for rock samples taken from the likely sites of HLW and SNF repositories or depositories, including metavolcanites from the area of PA Mayak and granitoids from the Krasnoyarsk MCC area. The comparative analysis of the obtained results served as a basis for proposing a system of methodological procedures for studying the permeability of crystalline rocks in sections of boreholes drilled in areas of likely allocation of HLW and SNF depositories and repositories.
