Development of Thermal-hydraulic Computer Code for Steam Generator

抄録

Understanding of the thermal-hydraulic behavior in the secondary side of the PWR (Pressurized Water Reactor) steam generator was required to improve the reliability of steam generator. Therefore, the thermal-hydraulic computer code FIT-III has been developed to predict the thermal-hydraulic behavior in the secondary side of steam generator. The FIT-III has been verified by using the two-dimensional and three-dimensional thermal-hydraulic test results. The verified FIT-III is used for the modification and design of the steam generator.
