To understand the structural property of borosilicate glass frit for vitrification of radioactive wastes, we prepared the glass frit samples which coordinated alkaline component and BO amount and measured the Si-O bridge structure of those samples by using Raman spectrometer. Moreover, we made the simulated waste glass samples which added non-radioactive nitrate solution to those frit and observed a change of Raman spectra by glass composition.
