【摘要】 本研究根据重庆涪陵核电厂厂址附近长江段水文资料、三峡库区的生态环境现状和温排水温度场预测结果,借鉴国外核电厂温排水的相关标准和国内水生生物的热影响指标,进行综合评价,分析拟建重庆涪陵核电厂温排水对三峡库区水生生物的影响。分析结果表明在最不利工况条件下,排水口附近表层温升不超过1℃,核电厂温排水温度没有超过鱼类繁殖和鱼苗阶段的适宜温度范围、鱼类生长适宜温度范围和回避温度,远达不到鱼类的起始致死温度,温排水不会对三峡库区中淡水经济鱼类的繁殖、育苗及生长产生影响。核电厂温排水的长期排放可能对排水口附近的浮游生物产生影响,但对整个三峡库区的浮游生物无影响。温排水对底栖生物的影响将比表层浮游生物的影响小,对整个三峡库区的底栖生物无影响。更多还原

【Abstract】 This study is based on the hydrological data near Chongqing Fuling Nuclear Power Plant along the Yangtze River,the present situation of the ecological environment of the Three Gorges Reservoir and the predicted results of thermal effluents from Chongqing Fuling Nuclear Power Plant.The standards of cooling water and the thermal tolerances indexes of aquatic organizms were investigated.The effects of thermal effluents on aquatic organizms were analyzed. The potential impact of Chongqing Fuling nuclear power plant to the Three Gorges Reservoir was explained.The results show that in the most adverse working conditions,the surface temperature near the outfall area is not more than 1℃,the temperature of thermal effluents do not exceed the suitable thermal range of fish breeding,growth and other thermal tolerances indexes.Thermal effluents from nuclear power plant have no influence about fish,plankton and benthic organisms in the Three Gorges Reservoir.更多还原
