Introduction  The development of nuclear power is an important measure to build a new low-carbon power system with clean energy as the main body in China. The research and development of super-large seawater cooling towers suitable for nuclear power plants can greatly expand the site resources of nuclear power plants.

  Method  The super large seawater cooling tower of nuclear power plant was a special structure, and its stress calculation belonged to three-dimensional space curved surface structure, and the section control was usually performed by the combination of wind loads. The maximum wind speed and design wind pressure of super-large seawater cooling tower in nuclear power plant were studied based on the engineering example of cooling tower design in nuclear power plant.

  Result  The suggestion and analysis method of design wind pressure value of cooling tower in nuclear power plants are put forward.

  Conclusion  The research can expand the resource reserve of nuclear power plant site.
