摘　　要：核电站最终热阱通常指接受核电站排除余热的大气或水体,或两者的结合。由于核电厂的热效率比火电厂低,因此核电厂冷却水量比同样容量的火电厂大。一般核电厂均建在有充分水源的江、河、湖、海边。本研究通过对两个滨海候选核电厂址——广东乌屿和广西防城港历年夏季日最高水温累积频率的分析以及用皮尔逊-Ⅲ型方法对乌屿站30年年最高水温进行频率和重现期分析,最后通过用CCSM3耦合模式对未来70年两站的水温变化进行预估,结果可为核电站最终热阱设计提供输入依据。Ultimate heat sink of nuclear power plant which usually is atmosphere or water or the combination of the two,is used to absorb the heat that nuclear power plant emits.Nuclear power plant＇ s thermal efficiency is lower than thermal power plant＇ s,so the amount of water which nuclear power plant need is more than thermal power plant.Most nuclear power plants are constructed adjacent to rivers,lakes and sea.Through analyzing cumulative frequency of past years＇ summer highest temperature of two seaside nuclear power plants—WuYu,Guangdong and Fangchenggang,Guangxi,as well as through analyzing frequency （return period） of Yunao station using the highest temperature of past 30 years by Pearson-Ⅲ method,finally using CCSM3 coupled model to forecast the SST of the next 70 years,to provide the basis for designing standard of ultimate heat sink of the two nuclear power plants.
