Disposition of the high-level radwaste repository of the RRC Kurchatov Institute

Paper deals with the peculiar features of the efforts to ensure abandonment of the high-active radwaste repository located at the Kurchatov Research Institute site. The radwaste bulk containing both the low-, the medium active waste and the high-active waste in metal containers was encapsulated in concrete. Paper describes the peculiar features of the radiation protection structure around the repository and of the processes used to break the concreted monolith to extract the radwaste. To detect the high-active radwaste or debris within the concreted monolith and to ensure application of the remote control manipulators one made use of the video-cameras and the gamma-visor. Paper dwells upon the peculiar features of the radiation situation on-line monitoring within the active area by means of the gamma-locator the information from which has been transmitted on-line to the PC to be processed and used in the course of the efforts
