ATHOS, exploited based on the porous media model, is a software for three-dimensional analysis of the flow and heat transfer in the steam generator of the nuclear power plant. Presents the application of ATHOS by simulating the complex secondary side heat and mass transfer in the steam generator of the nuclear power plant. Through the simulation, obtains the three-dimensional two-phase flow and the temperature field. The result can be used as the input of other researches, such as the analysis of flow induces vibration of tubes, the analysis of wear, the structure design, and so on. The research work of porous media model has valuable application in the design of steam generators in nuclear plants.
