OS0806 Study on the Primary Stress Limits of Aseismatic Evaluation for NPP Piping
Details
As the technical background by the domestic and overseas previous studies, only prevention of the fatigue damage was required as permission for the S class piping in the service condition Ds, and the primary stress limit for the purpose of the prevention of the plastic collapse was actually abolished in JEAC4601-2008. The plastic collapse of pipes is undeniable considering the variety of pipings. In this study, the needs was confirmed for stress limit for plastic collapse due to seismic load.
