摘要
Abstract
A fast open reactor design methods which involves flat cover,clamp and the end of cylinder were introduced.Comparing the results of GB 150 appendix C.7 and finite element method(FEM),it shows great differences between them.As for the third and forth equivalent stress at the end of clamp ring section,calculation based on appendix C.7 accounts for 51% ~56% of FEM,which errors from inhomo-geneous distribution of cross section shear stress,approximately the stress concentration factor is 2.In terms of the third and forth equivalent stress at the end of clamp and cylinder section,calculation in ac-cordance with appendix C.7 accounts for 1.41 ~1.96 times of FEM,the reason is stress in three dimen-sional tension,the third and forth equivalent stress is much less than axial stress.The sum of three princi-pal stress should less than quadruple design stress intensity values to prevent brittle fracture.Clamp fast open reactor belongs to fatigue vessel,in order to prevent stress concentration that exists in flat cover, clamp,end of cylinder,transition arc should be applied,transition arc radius will be one of the crucial fac-tors in fatigue vessel design.This paper investigates the effect of transition radius on the critical section equivalent stress and the relationship between transition arc radius and stress concentration factor.关键词
