Preliminary research work on building of repositories for burial of NPP radioactive waste in loess beds

The choice of a disposal site for burial of intermediate and low-level wastes from the NPS depends on a complex of conditions, requirements and methods resulting from the complex geologo-geographic and demographic conditions in the People's Republic of Bulgaria. The analysis of the geologic conditions shows that the various structures of the rocks, the tectonism, the seismicity in vast regions, the lack of plateau basalts hinder the choice of convenient sites for radioactive waste disposal. In Bulgaria the loess massives are studied and proposals are made to use them as a suitable environment for building of radioactive waste repositories
