Here we present structural studies of a simplified glass-matrix, − 55SiO 2♱0B 2O 3♲5Na 2O♵BaO♵ZrO 2 - upon adding lanthanide (Ln-)oxides: CeO 2, Nd 2O 3, Eu 2O 3, in two different concentrations 10% and 30w% each, to investigate the effects of lanthanides (Ln) taken as chemical surrogates for actinides. Understanding the effects of actinide addition to a borosilicate glass matrix is of great importance in view of waste immobilization. Borosilicate glasses are of great potential amongst the candidates of suitable inert materials for radioactive waste immobilization.
High level radioactive actinides are produced as a side product in reprocessing spent nuclear fuel, for which safe long-term-inert immobilizer matrices are needed.
