摘　　要：玻璃固化体是高放废物深地质处置场景下最有潜力的固化体形式,其化学稳定性直接决定了核素释放的速率和总量。本文综述了放射性废物玻璃固化体溶解行为和机理的研究进展,主要包括溶解动力学过程、相应控制机理及影响因素,以期为我国放射性废物处置工程安全评价提供参考。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.
