摘　　要：核电厂对极端降雨的应对能力直接关乎核电厂的安全生产。相较于恒定流推理公式法,数学模型法能够更加直观准确地反映降雨、径流及管网汇流过程。文章以我国某滨海核电厂为例,通过HYSWMM软件利用数学模型法进行极端工况下水淹分析。结果表明,数学模型法可对厂区积水点分布及最大积水深度进行直观展示,发现过流能力及运行负荷出现异常的管道与节点,由此可为厂房防水淹工作提供更为精准的工程指导,提高核电厂应对极端降雨的能力。The ability of coping to extreme rainfall of nuclear power plants is directly related to the safety production of nuclear power plants.Compared to the constant flow inference formula method,the mathematical model method can more intuitively and accurately reflect the rainfall,runoff,and pipe network convergence process.This article takes a coastal nuclear power plant in our country as an example and uses HYSWMM to analyze water flooding under extreme operating conditions using mathematical modeling methods.The results show that the mathematical model method can visually display the distribution of waterlogging points and the maximum depth of waterlogging in the factory area,identify pipelines and nodes with abnormal flow capacity and operating load,and provide more accurate engineering guidance for the waterproofing work of the factory building,improving the ability of nuclear power plants to cope with extreme rainfall.
