Dynamic features of HTR-10 once-through steam generator-an emulation study

Analysis of the dynamic features of steam generators is fundamental to the design and analysis of control systems to improve its performance. A dynamic model of the steam generator in the HTR 10 high temperature gas cooled reactor was developed to accurately model the distributed, non linear, and dynamic features of the once through steam generator running at full power. The results show that static emulation of this model agrees with its static design and experimental results. The dynamic emulation modeled the thermal hydraulic principle. The results well improve design of steam generator control systems.
