The development of technology and equipment for extracting actinides from radioactive waste reservoirs

Methods of reprocessing the radioactive silt from reservoirs in order to minimize the volume of waste and to fix the radionuclides are investigated. It is shown that it is possible to compact the suspensions into a granulated product, the volume of which is 15–20 times less than the volume of the silt. The process can be realized using different methods of compressing the silt. Preliminary fixing of the radioactive hydroxide suspensions in the form of granulated hydroxides and oxides ensures safe storage of the waste. When analzing methods of dealing with reservoirs it is best to organize silt reprocessing on the spot reliable consolidation and burial. State Scientific Center of the Russian Federation-VNIINM im.
