Abstract: Glass is the most potential solid phase for high level waste (HLW) immobilization in the deep geological repository conditions. Chemical durability is the key character of nuclear waste glasses, as it directly results in the leaching rate and total dissolved amount of radioactive nuclides containing in the glasses. In order to offer special reference for our nuclear disposal engineering, the dissolution behaviors of nuclear waste glasses, including kinetic regimes, relative controlling mechanisms and influencing factors, were reviewed in this paper. -
