Effect of cladding material properties on sealing performance of reactor pressure vessel with spherical head

308 L stainless steel is a commonly used cladding material of reactor pressure vessel. Due to the difference of surfacing process, its performance is quite different from that given in the standard. In this study, based on the stress-strain data of cladding 308 L measured in the laboratory, the elastic-plastic analysis of the sealing performance of the spherical head reactor pressure vessel were carried out by ANSYS finite element software. It...
