美国内陆核电厂环境特征

Environmental Characteristics of Inland Nuclear Power Plant in the USA

对美国内陆核电厂的环境特征进行了调研。调研结果表明:每个厂址最多建造3台机组,密西西比河流域一共分布20个厂址、31台机组;部分电厂近距离处涉及到生态环境保护区。在水源条件方面,多个电力公司专门筑坝截流为核电厂提供冷却水源,水资源较少的河流也建有滨河核电厂;内陆核电厂址多处于温和气候带,有些厂址尽管年平均相对湿度较大,但是年平均风速较大、年静风频率较小;厂址周围的人口密度小。

Environmental characteristics of inland nuclear power plants in the USA were investigated.The results showed that,no more than 3 units were constructed at each nuclear power plant site for instance.There are 31 units located at 20 sites along Mississippi valley.Some nuclear power plants are near ecological environmental protection area.As for aquatic resources,dams are erected to construct man-made reservoirs and supply cooling water for some nuclear power plants.However,some nuclear power plants were constructed beside rivers with limited aquatic resources.In many inland nuclear power plant sites,climate is mild,with high annual average wind speed,low calm frequencies although high humidity.Generally,population densities were very low around nuclear power plants.
