GB ASME & RCCM Analysis of Piping Design Camparison about Class 2 Components

Abstract:

Three primary nuclear technique of RCCM, ASME and the GB50267-97 code of China, have the similar classification of nuclear facility in nuclear power plant, including the code class and security class. The class 2 pressure pipeline design clauses in the 3 codes are similar, but are not identical. The earthquake input and the clauses about the class 2 pressure pipeline are compared. The results show that, when use the alternative damping values for response spectra analysis, GB and ASME are somewhat safer than RCCM in level B criteria, RCCM is somewhat safer than GB and ASME in level D criteria. In class 2 piping design code, RCCM stress assessment focuses more on the pressure, the GB and ASME is more focuses on considering the weight and occasional loads, in the lower pressure and the same stress intensification factor conditions, GB and ASME criteria are conservative than RCCM.
