Abstract:

冷却塔雾羽扩散直接影响冷却塔周围区域居民生活环境,是内陆核电厂散热系统运行环境影响评价时首要考虑的重要问题。应用冷却塔环境影响评价模型(SACTI),针对不同环境温度和风速变化情景下自然通风冷却塔雾羽特征参数进行模拟,以确定不同季节气象要素变化可能对冷却塔雾羽扩散产生的影响。研究表明,SACTI模型预测的不同温度条件下雾羽长度发生频率随温度增高呈下降趋势;雾羽高度发生频率随温度下降呈增加趋势、随温度增高呈减少趋势;雾羽半径发生频率随温度变化呈减少趋势。不同风速条件下,雾羽长度发生频率随风速增加呈增加趋势,雾羽高度发生频率随风速增加呈减少趋势,雾羽半径发生频率随风速增加呈减少趋势。冷却塔雾羽受温度和风速影响显著,直接影响不同季节冷却塔雾羽扩散。
