Dissolution rate of HLW glass changes depending on environmental conditions such as pH and groundwater composition. In this study, we measured dissolution rate of international simple glass (ISG) as a function of dissolved silica concentration under various pH conditions by using a Micro-Channel Flow-Through test method with Si-29 enriched silica solution.
