Formation of colloidal vaterite nanoparticles via mixing groundwater and uranyl.
Understanding hydrogeological conditions is crucial for selecting and assessing the long-term safety performance of a high-level radioactive waste (HLW) disposal repository. Utilizing environmental isotopes as effective markers analysing groundwater movement, this study investigates recharge sources, age, renewal rates using multiple in China’s potential HLW repository site, Beishan area. The results indicated deep bedrock primarily derives from ancient precipitation infiltration...
Abstract Heterogeneity is a natural characteristic of aquifers, which has profound influence on groundwater flow and solute transport. However, the heterogeneity in an aquifer difficult to characterize its impact response Earth tides remains insufficiently explored. A common thick aquifers decrease porosity hydraulic conductivity with depth. In present study, we analytical model that includes this particular both unsaturated saturated zones explore tidal response. Our results reveal that, as...
Residence time of deep groundwater is one the most important parameters in safety and performance assessment for high-level radioactive waste geological disposal. In this study, we collected samples Jijicao Gansu Beishan pre-selected region. The residence at two depths estimated by Helium-4 accumulation method were 3.8 ka 5.0 respectively upon measurement calculation, which indicates that not derived from crust circulation process. Hence, featured with long as well slow update rate, such...
Double packer equipment for hydraulic test can be used to measure pressure of zone directly, and it is frequently perform many kinds tests take groundwater sample from borehole. The method this mainly includes the design, implementation, interpretation synthetic analysis. By adopting double test, parameter distribution rock permeability along borehole acquired, as well connectivity, water conductivity bearing capacity disclosed structure chemical characteristics deep groundwater. It a...
摘要: 在核设施场址筛选和长期性能安全评价中,地下水化学特征是最重要的因素之一. 本文采用数理统计、离子比例法、同位素分析法以及水文地球化学模拟等方法,对沿海某核设施场址水化学特征及主要控制因素、地下水补给来源与年龄等进行了分析,并构建了该场址地下水循环演化模式. 研究表明:场址地下水中TDS较低,pH值多呈弱酸性;地下水化学类型主要为HCO3-Na·Ca型和HCO3-Ca·Na型;水化学组分主要受硅酸盐岩风化作用的控制;地下水主径流路径上以钠长石、钙长石的风化溶解为主;地下水来源于当地大气降水入渗补给,硐室深度范围内地下水14C表观年龄为2.08~3.60 ka. 该场址地下水化学特征及水循环交替条件对于保障该核设施的安全性是有利的. 关键词: 水化学 / 离子来源 水文地球化学模拟 同位素 核设施场址 地下水
Abstract As part of the suitability evaluation underground research laboratory (URL) candidate sites, hydrogeological investigation activity was conducted at Xinchang site in Beishan area from 2016 to 2019. A previous study discovered that rock masses URL site, which is surrounded by north–east trend and east–west faults, have low permeability shortage water-bearing structures. This article aimed describe hydraulic properties fault F31, located on west boundary evaluate characterization...
In the exploration and interpretation of extensive or global natural phenomena such as environmental monitoring, climatic analysis, hydrological meteorological service, simulation sea level rise, etc., knowledge about shape properties earth surface terrain features is urgently needed. However, traditional discrete grids (DGG) can not directly provide it are confronted with challenge rapid data volume growth modern surveying technology develops. this paper, a "natural"grid (GNG) model based...
The geological disposal of high-level radioactive waste is concerned with the systematic characteristics long-time scale groundwater. As part china site investigations and research associated waste, paleogroundwater in deep boreholes have been employed order to characterize groundwater flow fractured bedrock at Jijicao preselected site. By obtaining samples from borehole, this study focused on krypton isotope data, mixing relationship were analyzed, dating results corrected. It found that...
Deep geological disposal is internationally accepted as a feasible and safe way to dispose of high-level radioactive waste (HLW). Long-term safety assessment repository vital building confidence in waste. Many countries with nuclear power industries have carried out this work. The aim paper study the influence by fracture intersecting deposition hole or excavation damaged zone at located granite area. Furthermore, it also interest for addressing important aspects internal evolution canister....
Beishan region in Gansu was the preselected area for China’s high-level radioactive waste (HLW) repository. In selecting and evaluating a new dump site, tritium study is of great significance. The Xinchang-Xiangyangshan taken as an example. This paper selects typical unit tries to use distribution characteristics soil atmospheric precipitation infiltration recharge this area. results show: region, spatial variability content surface large; it feasible bound tracer method theory recharge; has...
