根据国际上推荐多重地质屏障体系作为高放废物地质处置方案,本工作实验研究了模拟高放玻璃固化体在5种地质介质(由花岗岩、膨润土、水泥、Fe3O4组成)中两年内的浸出行为。实验结果显示,玻璃固化体在花岗岩介质中的质量损失最小,在膨润土介质中的质量损失最大。扫描电镜分析结果 According to the internationally recommended multi-geological barrier system as a geological disposal program for high level radioactive waste, this work experimentally studied the leaching behavior of simulated high-rate glass solidification bodies in five geological media (consisting of granite, bentonite, cement and Fe3O4) for two years. The experimental results show that the mass loss of glass solidified body in granite medium is the smallest, and the mass loss in bentonite medium is the largest.
