摘要
岩体适宜性评价工作在高放废物处置工程中扮演重要的角色,其中地下水指标的研究尚需要进一步论证及完善。围岩裂隙水的侵蚀(地下水)会对处置库屏障隔绝性以及核素阻滞性产生影响,进一步整理相关国内外研究成果,并基于处置概念,对处置罐腐蚀和缓冲材料侵蚀的地下水影响因素分类,提出pH值、 Cl~-、 HCO_3~-、 SO_4~(2-)浓度,矿化度TDS值以及离子强度I均为需要重点考虑的指标,且不同处置罐材料类型,指标类型以及最适宜范围均有一定差异。
The work of pluton suitability classification plays a vital role in the construction of high-level radioactive waste disposal. The groundwater chemistry index, as part of classification factors, is need to be disserted and completed. The groundwater make apparent influence on the isolation and retardation of therepository barriers. this paper will classify and analysis the research achievement in canister and bentoniteerosion based on the disposal concept at home and abroad, so as to reconsider the classify the specificfactors such as pH, concentration of Cl~-、 HCO_3~-、 SO_4~(2-), TDS and I strength( ionic strength) and the value change in different canister material condition.
