Change of structure and properties of vitrified radioactive wastes during long-time storage in an experimental repository

Scanning electron microscopy, x-ray phase analysis, and infrared spectroscopy are used to study samples selected from a near-surface zone of glass blocks of vitrified radioactive wastes from nuclear power plants after they have been in storage in an experimental repository for 17 years. It is shown...

Description
Summary:Scanning electron microscopy, x-ray phase analysis, and infrared spectroscopy are used to study samples selected from a near-surface zone of glass blocks of vitrified radioactive wastes from nuclear power plants after they have been in storage in an experimental repository for 17 years. It is shown that only a thin surface layer of the glass blocks undergoes any changes due to environmental factors, and quartz-like and alumosilicate embryos are found on this layer.
