Introduction  The application of arial surveying on heat disposal to the ocean from nuclear power plants involves multiple issues.

  Method  The article introduced the issues include surveying technics, characteristics of survey area, surveying situations, and safety control, then summarized the measure by four sections which were the drone system applied, how to gather maritime temperature data around the nuclear power plants, how to monitor the fluctuation of maritime temperature with arial spectral instruments in summer tides; analysis of heat expansion in different tide conditions based on the data gathered. Finally, the results based on the measured data were summed up in the paper.

  Result  The practice shows that the procedure is approved reliable and can precisely gather information of temperature increment from power plant heat disposal in this task.

  Conclusion  The arial surveying on heat disposal to the ocean from nuclear power plants has many advantages over manual surveying.It can provide powerful reference for future research in how heat disposal affect the environment.
