核电厂水文地质概念模型与地下水监测井布设

为了做好核电厂附近地下水放射性监测，首先必须在分析厂址附近地形地貌、水文地质条件的基础上，初步确定厂址所在水文地质单元的边界条件和补、径、蓄、排关系，然后概化水文地质条件并建立水文地质概念模型，最后模糊判别地下水径流带，并以此指导厂址附近地下水找水方向和地下水放射性监测井位的布设。按上述思路，结合某核电厂址的水文地质条件，详述了水文地质概念模型的建立和地下水放射性监测井井位的布设原则及具体方案。

Hydro-geological conceptual model of nuclear power plant and layout of groundwater monitoring well

For better radioactivity monitoring of groundwater nearby nuclear power plants, firstly, the relationship of supplement, flowing, storage and discharge of runoff in the site area of nuclear power plant must be preliminarily determined, on the basis of the analysis on topography and hydro-geological conditions. The hydro-geological conditions are generalized and the hydro-geology conceptual model is established. The groundwater runoff belt is identified to guide the searching direction of groundwater and the layout of monitoring well of groundwater radioactivity. According to the above mentioned thoughts and in combination with the hydro-geological conditions around a nuclear power plant, a detailed presentation to the establishment of hydro-geology conceptual model, the layout principle and concrete layout scheme of monitoring well for groundwater radioactivity are introduced.
