| Abstract: | In this paper, thermal stress of SG lower plenum in typical load disturbance is analysed by finite element method. According to the thermal stress amplitude calculated and the design curve of low cycle fatigue, low cycle fatigue of the structure is assessed by ASME code.It can be concluded that no obvious low cycle fatigue of SG lower plenum occurs in typical load cycle. |
