Abstract: This paper is about the high temperature gas cooled reactor (HTGR-10) of China which is an experimental reactor. The thermo-fluid-solid coupling analysis for the steam generator of HTGR is performed in which the steam generator is modelled and then tested for some boundary conditions. The analysis is of key importance as Steam generator is very crucial component of a power plant system that ensures the safety and efficiency of a plant. To predict the thermal distribution in the tubes of a steam generator the coupled heat transfer between the primary and secondary sides must be considered. ANSYS Fluent is used for analysis that employs finite element method to achieve the task. The temperature distribution within the steam generator is analysed. The resulting temperature profile, pressure profile and the velocity profile for the coolant and feedwater is determined. In static structural analysis equivalent stress, equivalent elastic strain and the total deformation produced in the tube under such conditions is calculated. We see that the temperature of feedwater increases continuously as it moves upward in the tube while the coolant (He gas) temperature decreases as it goes down through the shell. The pressure of a coolant decreases as it flows downwards in the shell and consequently its velocity increases in the said direction. The velocity of a feedwater increases gradually as it rises up in the tube due to gradual decrease in its pressure. The equivalent stress, equivalent elastic strain and the total deformation produced in a tube are highly dependent on system temperature, tube material and the geometric configuration of tube.
