Abstract

The recent advances in HLW partitioning indicate that cesium–137 and strontium–90 can be separated in the form of a pure concentrate. Based on this concentrate the glass RT2–1 containing 4.7 wt.% Cs2O and 2.7 wt.% SrO was selected for more intensive and wider studies to predict long-term performance of this waste form under repository conditions.

Leach tests were made in distilled and mineralized water before and after crystallization at 20, 90 and 130°C.

Fully devitrified glass contained only one crystalline phase corresponding to the pollucite structure.
