The article focuses on the topical problem concerned with disposal and isolation of radioactive waste (RAW), namely, the theoretical and experimental validation of suitability of geological formations to be a barrier for deep disposal of high-level waste. The authors display the complex and diversified nature of characteristics, events and processes that influence underground isolation facilities for RAW. Objectives and methods of the research to find values of the initial data for the prediction of safety of geological RAW disposal are identified. The article presents the substantiated design of a set of studies into properties and condition of rock mass intended for RAW disposal, the related procedures and instrumentation, and the problems to be solved to predict and ensure safety at all stages of lifecycle of geological RAW disposal and isolation facility. The research used the many-years experience of control over crystalline rock mass with analogous geological conditions, in the present authors’ opinion, to the facility planned for RAW disposal in Nizhnekansky Granitoid Massif.
