Abstract

To decide the final fate of high-level radioactive wastes that are in Krasnoyarsk Land, Russia, and, most importantly the wastes from a weapons complex at the Mining-Chemical Combine (MCC, Krasnoyarsk-26), suitable sites for geological disposal of the wastes are being sought in Middle Siberia. The ultimate goal is to select one site for development of a repository for these wastes. As a result of complex geological-geophysical work completed to date, the two most promising sites are in the northern part of the Nizhnekanskiy granitoid massif (the Yenisei Ridge). These sites are approximately 25 km from the MCC. Based on geotectonic analysis and electrical surveying data, these sites are composed of low-permeability biotite granite that extends to relatively great depth. At present, both sites are undergoing more detailed studies to define the most suitable one for detailed geological exploration. Radiogeochemical studies showed that granitoid rock samples from the massif exhibited high retention for major long-lived radionuclides in the wastes. The general results of the investigations are presented.
