摘　　要：针对内陆核电厂周围人口稠密、濒临大型水体的特点,给出了核电厂严重事故时放射性烟羽释放造成水源污染的可能情景和有关的计算模式,并对假想的位于南方滨湖(库)厂址进行计算。结果表明,事故释放后,干湿沉积和地面径流途径对核电厂周围水体造成的放射性污染短时间的核素浓度远高于GB 18871—2002规定的食品通用行动水平,对公众所致的剂量是不可接受的。In-land nuclear power plant sites of China are usually located in densely populated area and are close to large surface water. This paper proposed scenarios and corresponding calculation models for water contamination caused by radioactive plume release after a severe accident. The models were applied to an imaginary lake （ reservoir） -adjacent site in the south of China. The results showed that, the shorttime concentration of radioactivity in the lake due to dry and wet deposition and runoff was higher than the generic action levels for foodstuffs in GB 18871--2002, and the public dose resulted was unacceptable.
