摘　　要：滨海核电厂海域水下地形及水动力条件复杂多变,温排水与液态流出物的输移扩散受潮流及温差异重流影响较大。本文简要介绍了我国滨海核电厂温排水和液态流出物研究方法;分别就理论分析、数学模型计算、物理模型试验、原型观测及后评估等研究手段进行系统评述,阐明各研究手段的研究进展及优缺点,并结合温排水数学模型和物理模型各自特点和工程运行实际,得出在核电厂冷却水研究过程中物理模型和数学模拟应相互结合、互为补充,最终给出在排水口近区海域宜采用物理模型模拟其水力热力特性,远区海域宜采用数值计算的结论。为进一步提高工程安全性及满足生态环境的保护要求,应加强原型观测及工程后评估等工作。The underwater topography and hydrodynamic conditions of the coastal nuclear power plant area are complex and changeable,and the transport and diffusion of thermal discharge and liquid effluent are affected by the current flow and temperature difference reflow.This paper briefly introduced the research methods of thermal discharge and liquid effluent of coastal nuclear power plants in China.The research methods such as theoretical analysis,numerical simulation,physical testing,prototype observation and post-evaluation were systematically reviewed.The research progress of various research methods was given,and their advantages and disadvantages were analyzed.Combined with the respective characteristics of the mathematical model and physical model of thermal discharge and the actual operation of the project,it is preliminarily discussed that the physical model and mathematical simulation should be combined and complement each other.The physical model should be used to simulate its hydraulic and thermal characteristics in the sea area near the drainage outlet,and the numerical calculation should be used in the distant sea area.In order to further improve the safety of the project and to meet the protection requirements of the ecological environment,the work of prototype observation and post-engineering evaluation should be strengthened.
