GEN IV Webinar Series: Scale Effects Analysis on the Thermal Hydraulic Behavior of Impinging Jets in Sodium Fast Reactors, March 23, 2022, 8:30 am EDT

Body

In the industry and especially in the nuclear field, simulation software plays an important part on the study of new prototypes, as building scale 1 prototype is both complex and expensive. To assess new design options and validate associated simulation software, most experiments are performed on small-scale mock-ups. However, distortions of a studied phenomenon can occur from a small-scale model to a prototype: this is known as scale effects. Without understanding of these effects, results from models cannot be transposed to the prototype scale and numerical results cannot be validate either. In the French SFR project, an important problematic is the raise of the core jets in the upper plenum for specific operating conditions. When these jets raise, the flow pattern in the vessel is modified and leads to thermal fluctuations reducing the lifetime of the reactor’s components because of thermal fatigue. While this raise can be observed on small-scale mock-up, it is important to be able to characterize both this phenomenon and its transposition. For this purpose, Benjamin Jourdy works on a methodology based on bibliography synthesis and experimental results, leading to the conception of a new mock-up dedicated to this study.
