| 摘 要： | 利用某厂址全年逐时的气象观测数据，通过Calpuff模式模拟计算了不同事故工况下核电厂放射性流出物对周边水资源可能造成的污染情况。计算表明:利用真实的风向、降水等气象条件模拟计算结果更加合理，选址假想事故和IC释放类工况造成的水库沉积核素浓度远低于GB 18871-2002规定的食品通用行动水平。尽管采用了更真实的气象条件，BP释放类造成的核素沉积浓度仍高于国标中规定的食品通用行动水平，因此在设计上应避免此类严重事故的发生。

| Abstract: | Using whole year hourly meteorological data of one site, water contamination caused by radioactive plume release after accidents of NPPs was modeled using Calpuff model. The results showed that, it was more reasonable using realistic meteorological data like wind direction and precipitation etc, and concentration of radioactivity in the reservoir caused by postulated accidents for sitting and IC release category was much lower than the genetic action levels for foodstuffs in GB 18871-2002. But the concentration of radioactivity caused by BP release category was still higher than the genetic action levels for foodstuffs in GB18871-2002 despite using realistic meteorological data, so such sever accidents should be avoid in design. |
