Abstract

Abstract

The anti-vibration bars are critical to the integrity of tubes for steam generator during operation. Taking the steam generator of Generation 2⁺ for example, the potential effects of anti-vibration bars on the integrity of SG tube is analyzed. It is concluded that the anti-vibration bar twist, the gap between anti-bibration bar and tube, and the insertion depth of the anti-vibration bar are very important to the tube integrity. Based on the conclusions, optimizations are proposed to make the tubes more reliable during operation.
