The Effect of Interfacial Material on Tailored Ceramic Nuclear Waste Form Dissolution

摘要: The long radioactive lifetime of the fission products in nuclear wastes requires that material be isolated from biosphere for periods 103 to 105 years. One method accomplishing this is consolidate waste into a chemically stable solid form contained within multiple barrier canister which can transported geologically repository long-term storage. A number candidate forms are being assessed determine their suitability incorporating various compositions. These include current reference (borosilicate glass), ceramics, high silica glasses, and cementitious forms. In laboratory, research currently conducted on immobilizing synthetic alumina content tailored made by temperature pressure consolidation with selected additives produce fully dense, fine grain ceramic.1 specific crystalline phase assemblages produced tailoring sludge provides chemical host sites individual radionuclides ceramic phases closely approximate natural mineral have proven stability over geologic time scales.
