| 摘 要： | 本文以秦山核电工程多堆厂址为例,当正常运行工况下年均气态放射性污染物浓度分布采用极坐标方式表示时,提出了2种多源时污染物浓度迭加的计算方法。方法1是直接根据各污染源对网络点浓度贡献进行迭加,具有可靠的精度。方法2是建立一个等效源,适合于污染源相对集中的情形。

| Abstract: | As an example of multi reactor sites of Qinshan nuclear power project, two methods are developed for overlapping concentrations caused by normal emission of multi source when concentrations of airborne radioactive contaminants expressed in polar coordinate.The first method is to calculate concentrations according to the concentration contribution of various sources to grids,with good accuracy.The second method supposes that concentration distribution would be caused by an equivalent source in the case of centralized distribution of sources. |
