Title: The problem of burying radioactive wastes containing transplutonium elements (TPE)

Abstract

This paper discusses the problem of burying radioactive wastes containing TPE. The most acceptable and developed method at present is that of disposal into continental, deep-lying, geological formatins. Based on an analysis of estimates of the thermal conditions on burying highly active wastes, including TPE concentrates, data on the filtration and sorption characteristics of rocks, estimates of the diffusion of radionuclide species capable of migrating, and taking into account the retention powers of rocks it is concluded that it is possible to bury such wastes in weakly permeable geological formations possessing shielding characteristics which ensure reliability and safety in burial.

  • This paper addresses the problem of processing and burying radioactive wastes. The vitrification of liquid waste containing large amounts of alpha emitters, e.g., transplutonium elements, is discussed. The authors create a test unit in a hot cave that could operate on actual high activity waste. They studied the digestion of phosphate glass under various conditions to obtain glass blocks of up to 0.5 kg containing fission products, and they studied the behavior of radionuclides in a gas purification to determine its efficiency. The physicochemical properties of the solid product were examined; this included the study of glassy products by differentialmore » thermal analysis and x-ray diffraction. The electrical conductivity of the melt, the retention of radionuclides in the glass, and the hydrolytic stability of the glass were also examined.« less
  • In the USSR, creating reservoirs for liquid radioactive wastes is one of the promising methods of safely disposing of them in deep water tables, in zones with a standing regime or a slow rate of subterranean water exchange. The results of investigations and the practice of burying (the wastes) indicate the reliability and effectiveness of such a method of final waste disposal when the basic requirements of environmental protection are observed. Geological formations and collector strata that guarantee the localization of the liquid radioactive wastes placed in them for many tens and even hundreds of thousands of years can bemore » studied and chosen in different regions. The basic requirements and criteria to which the geological structures and collector strata must correspond for ensuring the safe burial of wastes have been formulated. Wastes are buried only after a comprehensive, scientifically based evaluation of the sanitary-radiation safety for this generation and future ones, taking into account the burial regime and the physico-chemical processes that accompany combining wastes with rocks and stratal waters, as well as the time of holding wastes to maximum permissible concentrations. Positive and negative factors that characterize the method are analyzed. Possible emergency situations with subterranean burial are evaluated. The composition and methods of the geological survey, hydrodynamic, geophysical, physico-chemical and sanitary-radiation investigations; methods of calculating and predicting the movement of wastes underground;methods of preparing wastes for burial and chemical methods of restoring the suitability of wells; design characteristics and conditions of preparing wells for use; methods of estimating heating and processes of radiolysis for a medium containing highly radioactive wastes; methods of operational and remote control of the burial process and the condition of the ambient medium, etc. are briefly examined.« less
  • Within the range of realization of national programs of treatment with radioactive wastes the problems of localization and burial of solid tritium-containing wastes is of great importance. This problem is characterized by a number of peculiarities connected with the localization of tritium-containing wastes on one side and on the other hand, it requires the specific approach connected with the diversity of ways of tritium migration into the environment with its genetic significant, and as a rule, with extremely high waste activity. As a metal-sorbent in given products, titanium is used in a form of thin films sprayed on various metalmore » backings. Mainly, the corrosion-resistant materials are chosen for backing materials such as, molybdenum, copper or stainless steel, made in a form of discs or rectangle plates with thickness from 0.1 to 2 mm and area of 20 cm{sup 2}. The activity of one article may be attained to 100 Ci. Tritium is well sorbed by titanium at the temperature approximately 400 C (its solubility reaches 467 cm per 1 g of titanium) and is relatively well kept by it up to this temperature.« less
