Maintaining the structural integrity of the major devices of a nuclear power plant is perceived
as a particularly important issue in relation to the stability of the structure, and the structural …

To secure the nuclear power plant (NPP) safety, it is essential to improve the seismic
performance of piping systems. Accordingly, to achieve this purpose effectively, applying a …

Isolation design enhances the safety of nuclear islands during earthquakes. Magnification of
isolation layer displacement increases the damage risk of the nuclear pipeline crossing the …

Nuclear power plants are high risk facilities due to the possibility of sudden seismic events,
because any possible failure could initiate catastrophic radioactive contamination. The …

The pipeline connecting the isolated nuclear island and the non-isolated turbine building is
prone to significant relative displacements during intensive earthquakes. Generally, elbows …

This paper presents the second part of a two-part investigation on the seismic performance
limits of nuclear power plant piping systems with seismic isolation systems considering the …

An isolation system installed in a nuclear power plant (NPP) could increase seismic safety
during seismic events. On the other hand, a more significant relative displacement may …

A methodology to evaluate the seismic performance of interface piping systems that cross
the isolation interface in the seismically isolated nuclear power plant (NPP) was developed …

In this study, a steel frame that realized the second floor of a structure was fabricated in
referring to NFPA 13. In addition, a riser pipe system with groove joints was installed, and a …

The interest in the seismic performance of nuclear power plants has increased worldwide
since the Fukushima Daiichi Nuclear Power Plant incident. In Korea, interest in the seismic …
