Project summaryThe Project proposed corresponds to the tasks and the Statute of ISTC in the field of environmental protection, development and safety endurance of nuclear energy.
– scientific substantiation of the choice of a geological formation and a particular block of rooks within the southern end of the Yenisei Ridge for disposal of partitioned high-level wastes (HLW) of the RT-2 plant;
– conduction of complex geological, geophysical and geochemical investigations of rocks to assess the safety of radionuclides long-term isolation;
– working out the basic documents: conception, criteria, analysis of a, geotechnological isolation system and a system of radionuclides migration as applied to Pre-Cambrian granite-gneiss formation of the Yenisei Ridge.
– location of alternative sites for construction of an underground repository in the southern part of the Yenisei Ridge based on the optimization of complex criteria for safe isolation of radioactive wastes in geological formations;
– substantiation of requirements on the choice of a mountain massif for creating a long-term isolation system of solidified HLW;
– a model and structural-functional analysis of radionuclide migration processes in a geotechnological system of waste isolation;
– a regional conception and criteria for underground disposal of solidified HLW in geological formations of the Yenisei Ridge;
– basic principles for the prediction of radionuclide long-term isolation in ancient platform blocks.
Project proposed gives comprehensive geological substantiation of feasibility of solidified HLW safe disposal in structural-tectonic blocks of the Yenisei Ridge near the RT-2 plant. The stage of preliminary designing to create an underground repository for a large Russian radiochemical plant is realized.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
