摘要：

This work examines secondary phases formed on the surface of radioactive borosilicate glass K-26 during 12 years of testing in the loamy soil. This glass has been produced to immobilise intermediate level operational nuclear power plant (NPP) radioactive waste. An altered layer has been formed at the glass surface that had been contacting with the repository environment. The layer is morphologically following the bulk waste glass. The layer is chemically inhomogeneous and non-uniform in thickness and structure. It contains in addition to the major vitreous phase, alpha quartz, calcite, aluminium hydrochlorides, and molybdenum compounds.
