The nuclear power station needs to drain a mass of cooling water to the near-sea area during its operation. Its influence on surrounding environments and the running of the station itself needs further research on the distribution and the features of the sea surface temperature field in different seasons and under different tide conditions. The research can also validate the effect of the cooling water and the Temperature Drainage Mathematic Model as well as the Physical Analogue Model. The authors carried out airborne thermal remote sensing survey of the temperature field near the nuclear power station in the belief that airborne thermal remote sensing survey has the advantage that it can obtain high resolution sea surface temperature under different tide conditions. Data processing was carried out, and the result can provide reference and ideas for thermal drainage remote sensing survey of the nuclear power station.
