Research progress on thermal discharge and liquid effluent from coastal nuclear power plants in China
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 efflu-ent 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 obser-vation 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 respec-tive 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 simula-tion 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 calcula-tion 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.
