ANNOTATION:

The conditions in the crystalline geological massif, which determine the long-term safety of radioactive waste disposal, are reduced to two fundamental factors - the features of the host rocks and the fracture network inherent in the studied area of the massif [3]. Refinement of the parameters identified at the early stages of geological study of cracks is one of the highest priority tasks in the safety assessments of the radioactive waste disposal. These parameters should also be taken into account in the formation of requirements for the composition and structure of the system of engineering barriers preventing the release of radionuclides outside the disposal. The presented material contains a description of the work and the approaches applied in processing the results of borehole surveys of the prospecting and appraisal stages of geological exploration of the Yeniseisky area, performed using the specialized probe with video logging equipment.

Keywords: radioactive waste, radioactive waste disposal, underground research laboratory, rock mass characterization, studies of the near-wellbore zone, video survey of wells, identification of the main fracture systems.
