Effect of bending on the geometry and collapse pressure of helical steam generator tubes: Numerical study

This study investigates the effects of bending processes on the geometry and collapse pressure of helical steam generator tubes used in Small Modular Reactors (SMRs). The bending process induces geometric imperfections such as ovality and eccentricity, as well as work hardening, which significantly...
