Abstract: 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 storage 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.

Key words: groundwater； environment assessment, rock feature dominated groundwater, tectonic dominated groundwater； nuclear power plant
