高放废物处置库新疆阿奇山预选地段地下水同位素研究

Isotopic Study of Groundwater in Aqishan Preselected Section for China’s High Level Radioactive Waste Disposal Repository

摘要: 本文以我国高放废物处置库预选地段之一的新疆阿奇山地段为例，在野外调查、样品测试基础上，重点讨论了该地段地下水同位素特征及其水文地质意义，并结合地段水文地质条件，识别研究区内地下水的来源及其交替能力。结果表明，阿奇山地区地下水主要源自当地大气降水入渗补给，深部地下水交替能力明显弱于浅部地下水。

Abstract: Taking Aqishan preselected section of high level radioactive waste disposal repository in our country at present stage as an example, based on the field investigation and sample measurement, the isotopic characteristics and its hydrogeological significance were studied. Combined with hydrogeological conditions, the origin and alternation ability of groundwater were recognized. The results show that the groundwater in study area is mainly recharged from infiltration of local rainfall. The alternation ability of deep groundwater is clearly weaker than that of shallow groundwater.
