Seismic fragility evaluation of the base-isolated nuclear power plant piping system using the failure criterion based on stress-strain

open access: yesNuclear Engineering and Technology, 2019
In the design criterion for the nuclear power plant piping system, the limit state of the piping against an earthquake is assumed to be plastic collapse. The failure of a common piping system, however, means the leakage caused by the cracks.
