摘要
本文叙述了核废物地质处置研究领域中涉及天然和人为类似物研究中的一些矿物学问题。在自然界的天然玻璃、膨润土、晶质铀矿等分别作为高放废物玻璃固化体、高放废物处置库的缓冲 /回填材料和乏燃料的天然类似物 ,考古遗址中的玻璃和青铜器文物作为人为类似物。通过这些天然非晶质结晶物质和人造制品的稳定性研究来预测未来 10 0 0 0~ 10 0 0 0 0a间处置库中废物和缓冲 /回填物质的变化、放射性核素迁移规律 ,为高放废物处置库的设计和建造提供重要科学依据 ,提高公众对高放废物安全处置的信心。
Some mineralogical problems involving in natural and anthropogenic analogues studies in the field of nuclear waste disposal are described in this paper. Natural glass, bentonite and uraninite are present as natural analogues of vitrified waste for high-level radioactive waste, buffer/backfill material and spent fuel respectively; glass in archeological monuments and bronze relics as anthropogenic analogues respectively. Through stability studies of natural non-crystalline and crystalline materials and artificial artifacts, changes of wastes and buffer/backfill materials and migration behavior of radioactive nuclides can be predicted in repository during forth-coming 10 000~100 000 years. Scientific evidence for the design and construction of repository and confidence to public for safe disposal of nuclear wastes can be provided.
