Tectonic Processes Modeling and Development with Time in the Areas of HLW Disposal
The possibility of using deep geological formations to dispose of high-level radioactive waste (HLW) is a subject raising heated debate among scientists. In Russia, the idea of constructing HLW repository in the Niznekansky granitoid massif (NKM) in Krasnoyarsk area is widely discussed. To solve this problem we are elaborating a technology associated with time - space stability prediction of the geological environment, which is subject to geodynamic processes evolutionary effects. It is based on the prediction of isolation properties stability in a structural tectonic block of the Earths crust for a given time. The danger is in the possibility that the selected structural block may be broken by new tectonic faults or movements on a passive fault may be activated and thus underground water may penetrate to HLW containers.The technology comprises the following complex of research methods.1.Structural geology, engineering geology and geomorphology methods of fault block tectonics.2.Heterogeneous finite-element modeling of stress fields distribution in structural blocks.3.Paleotectonic reconstruction of stress - strain state of the areas under investigation for a period of time of up to 1 million years.4.Zoning of the area and separation of deep linear zones from geological and geophysical data that can be potential zones of tectonic faults on the basis of artificial intelligence methods.5.GPS-observations of modern movements of the Earths crust.6.The method of rock destruction time calculation on the basis of the kinetic theory of solid bodies strength.
