与环境相关的水文条件在核电厂厂址比选中的考虑

参照国内外核电厂厂址选择的相关法规和标准的要求,从洪水、取水、排水和地下水等与环境相关的水文条件中选取相关的特征参数,并分别从厂址安全、建造投资、环境辐射影响等角度进行了优劣比较。厂址洪水条件主要考虑了核电厂厂坪标高和厂址设计基准洪水水位的差值;取水条件主要考虑了岸滩稳定性、水深条件、水量、输水干线长度、水体平均含沙量和水资源分配等指标;排水条件主要考虑了水弥散特征和受纳水体的规模;地下水条件主要考虑水文地质单元独立性和地下水开发利用程度。

Consideration on hydrological conditions related to environment for sitting of nuclear power plants

With reference to relevant requirements of regulations and standards for domestic and foreign nuclear power plant siting, the hydrological parameters related to environment were selected from the flood, water intake, drainage and groundwater.The advantages and disadvantages were compared respectively in terms of site security, construction investment and environmental radiation effects.In flood, the difference between NPP floor elevation and DBF level was considered.In water intake conditions, the stability...
