Abstract
Official abstract text for this publication.
This invention relates to the vitrification of radioactive waste products. According to this invention, a glass composition, which is suitable for low-level radioactive waste resins, and a method of vitrifying the low-level radioactive waste resins using the same are provided to significantly reduce the volume of radioactive waste products and to vitrify low-level radioactive waste products using the glass composition, which is suitable for vitrifying the low-level radioactive waste resins, thereby maximally delaying or completely preventing the leakage of radioactive materials from a glass solidified body.
First claim
Opening claim text (preview).
What is claimed is: 1. A glass composition for vitrifying a low-level radioactive waste resin, the glass composition comprising: 30 to 40 wt % of SiO 2 , 6 to 9 wt % of Al 2 O 3 , 9 to 13 wt % of B 2 O 3 , 15 to 22 wt % of CaO, 7 to 9 wt % of K 2 O, 2 to 5 wt % of MgO, 4 to 9 wt % of Na 2 O, 3 to 7 wt % of Li 2 O, and 0.5 to 3 wt % of MnO 2 .
