Abstract	This paper provides a combined thermal hydraulic and vibration analysis of the Yonggang Nuclear (YGN) 3/4 steam generators using a developed ATHOS3 code model to calculate the multi-dimensional two-phase flow distribution, and ANSYS code to calculate the free and forced responses of a specific U-tube. The local porosity idea has been used for the ATHOS3 step 1 model development and the flow-induced vibration. The step 2 model development in the tube lane region was carried out to change into rectangular modes which separated the hot and cold sides of inverted U-tubes and to enhance understanding of the difference between ATHOS3 and Flow 3 modeling. Stability ratios for the tube vibration has been calculated using the developed ATHOS3 model and ANSYS code. The results of this analysis for YGN3/4 steam generators show that the design goals were met for all three critical regions of cross flow, with the stability ratios much less than 1.0.
