Positronium Study of Structural Nanovoids in Model Glassesfor High-Level Nuclear Wastes

摘要：

High-level radioactive nuclear waste is immobilized by mixing it with glass to be stored safely for a long time more than 1000 years 1. These radioactive nuclides are confined in the intrinsic structural nanovoids of the radioactive waste glasses (RWG), usually SiO2-B2O3 based glasses. Thus it is very important to study how the nanovoids are occupied by the radioactive nuclide atoms (ions) and stable under the irradiation environment during the long-term storage.
