滨海核电厂温排水相关若干问题研究

温排水是核电厂环境影响评价、取排水工程方案确定及工程可行性论证中需考虑的重要因素。本文针对核电厂取排水工程中与温排水散热特性相关的若干重要问题进行了研究和论述。结合海南昌江核电厂取排水工程设计、温排水模拟和温度场原型观测成果，对取排水明渠或管道中的水温沿程变化、取排水岸上回流时间迟滞、海域水面散热计算、淹没深层排水的三维水力热力特性等问题进行了论述，总结了当前研究中需要改进的内容，并给出了进一步优化与水温相关的设计、科研等方面的方法。

Study on several issues related to thermal discharge of coastal NPPs

Thermal discharge is an important factor to be considered in the environmental impact assessment, the determination of water intake and discharge projects and the feasibility study of the nuclear power plant projects.In this paper, several important issues related to the heat dissipation characteristics of thermal discharge in water intake and discharge engineering of coastal NPPs are studied and discussed.Combined with the design of water intake and drainage engineering, the simulation of temperature and drainage and the prototype observation of temperature field in some coastal NPPs in China, the changes of water temperature along the open channel or tunnel, the delay of recirculation on the shore, the calculation of sea surface heat dissipation, and the submerged deep drainage are discussed.The article also summarizes the contents that need to be improved in the current research, and gives some methods to further optimize the design and scientific research related to thermal discharge.
