Abstract

Abstract

The adverse conditions in a severe accident,such as repeated alternation of cold and hot conditions or the pressure difference between RCS（Reactor Coolant System） and the secondary side,may induce the creep rupture of steam generator tubes.Based on the typical accident sequences defined by level 1 PSA analysis,this study identifies the effect of thickness reduction of steam generator tubes on inducing SGTR and analyzes the effectiveness of severe accidents mitigation measures,such as RCS depressurization and recovery of feedwater to SG.
