Conditioning of radioactive ash residue in a wave of solid-phase exothermal reactions

The possibility is studied of using the hear of exothermal reactions in the solid phase for conditioning the ash residue produced when solid radioacti ve wastes are burned. It is shown that solidifcation of the ash wastes can be performed without input of energy from external heat sources with the fi nal glassy product containing 50-60 mass % ash residue and meeting the requ irements for solidified radioactive wastes. The conditioning is performed i n a special crucible-container intended not only for performing the process but also for subsequent storage or burial of the final product. 5 figures, 2 tables, 10 references.
