Study on Calculation Method for Heat Transfer of Cooling Pipe in Pressurizer Relief Tank

In the design of the improved nuclear power plants, there are many changes in the system parameters of the pressurizer relief tank. As an important component for the heat transfer system in the pressurizer relief tank, the cooling pipe must be redesigned based on the heat transfer calculation. This paper analyzes the complexity of the heat transfer calculation, and gives a simplified model and relevant calculation method.
