Base isolation can be used to reduce seismic response of structure and protect the structure from damage subjected to earthquake.
To study the isolation effect of new PWR nuclear power plant with a base isolation system, considering FSI (fluid-structure interaction) effect by the simplified model, two 3D numerical models (one nonisolated model and one isolated model) were established.
After natural frequency analysis, one artificial ground motion was chosen to analyze isolation effect qualitatively.
Based on the results, the accelerations and relative displacements of nuclear island building under ten natural ground motions were statistically analyzed to evaluate the isolation effect quantitatively.
The results show that the base isolation system can reduce the natural frequencies of nuclear island building.
Horizontal accelerations can be reduced effectively, but the isolation effect is not obvious in vertical direction.
The acceleration reduction ratio of the top is about 70%–90%, and the acceleration reduction ratio of the lower part is about 20%–60%.
Horizontal displacement of the isolated model is far larger than that of the nonisolated model, and horizontal displacement will become larger considering FSI effect.
These conclusions could provide some references for studies on the isolation system of nuclear island building.
