Abstract
One of the essential components in a pressurized water reactor is the steam generator (SG) that has an important role in efficiency of nuclear power plants. In the present work, a horizontal steam generator (HSG) was investigated based on entropy generation as a consequence of second law of thermodynamic. The thermal hydraulic operation parameters were calculated by considering a single-phase model for the primary loop related to the tube and two-phase model for the secondary loop related to steam generator shell. Then, the effect of each parameter against different constraints such as length-to-diameter ratio, mass flow rate, tube diameter, and inlet temperature on the generated entropy was investigated. To validate the physical equations and the framework used in this model, the results of the developed code are compared with the research articles related to enthalpy generation. The results showed that a significant increase in length-to-diameter ratio and tube diameter resulted in a decrease in entropy generation number (EGN). Therefore, it is concluded that decreasing the entropy generation enhances the performance of steam generators as well as their economic efficiency.
