核电厂地下水环境影响评价需关注的几个问题

摘要

基于目前国内核电厂地下水环境影响评价现状,结合水文地质、工程地质、石油地质领域已有研究成果,提出了核电厂在一定尺度时空内进行水文地质建模时,需关注的几个问题:建模范围内涉及岩石的岩性特征、构造特征、储集类型、渗流类型,深化认识地下水蓄水构造类型和地下水类型,应充分考虑建模范围内不整合、风化壳、断层的发育及空间配置关系及其对地下水的输导作用.%Based on the present -day situation of groundwater environment assessment at the site of nuclear power plant in China and combining the research achievements in hydrology geology, engineering geology, oil geology, it is pointed out that when establishing hydrogeology model in a certain range around nuclear power plants,it is necessary to pay attentions on the rock characteristics,geologic structure,water storage condition,seepage type,and to deepen understanding on the groundwater stor-age structure type and groundwater type and give a full consideration on non -integration, weathering crust, fault development and spatial relation and their influence on the underground water transfer.
