Temporal-spatial characteristics of thermal discharge from Liaoning Hongyanhe Nuclear Power Plant in summer based on aerial remote sensing data
摘要
Abstract
Based on aerial remote sensing data and field observation data,we analyzed the temporal-spatial char-acteristics of thermal discharge from Liaoning Hongyanhe Nuclear Power Plant in summer.Results show that the temperature retrieved from aerial remote sensing data are strongly correlated with the field observation temperat-ure and thereby are reliable.There is a similar spatial distribution of thermal discharge under the same tide state from spring to neap tide.Water depth and tidal current are important factors on the diffusion range and the direc-tion of thermal discharge high-temperature area.Once the thermal discharge spreads offshore to a certain distance,the water velocity and depth are significantly higher than those in nearshore area,which is conducive to the rapid mixing of thermal discharge with cold water,prompting the rapid diffusion of heat with a sharp drop in temperat-ure.Meanwhile,the periodic variation in water velocity(flood and ebb tides)determines directly the diffusion dir-ection of thermal discharge.Drone remote sensing monitoring by unmanned aerial vehicle can effectively com-pensate for the inherent limitations of temporal-spatial resolution of satellite remote sensing monitoring,and has higher accuracy.It can be used as the core technical means for the dynamic monitoring of thermal discharge from nuclear power plant in the future.关键词
