Abstract

Abstract

The ASME B＆PV Code Section Ⅲ– Division 1 – Subsection NB Design-by-Analysis（NB-3200） approach provides stress limits for the design of nuclear components.In the present paper,the failure modes in nuclear components are identified.The characteristic of Design-by-Analysis was presented.Moreover,the technical basis and background on some criteria of NB-3200 is presented.Specifically,shakedown and ratcheting（NB-3222.2）,thermal stress ratcheting（NB-3222.5）,simplified elastic-plastic analysis（NB-3228.3）,Poisson’s ratio correction（NB-3227.6） and fatigue（NB-3222.4）.The author hopes that the above discussion will deepen the analyst’s understanding of the code and help them have better practical application of the code.
