Energy storage power station seismic isolation

Why do nuclear power plants need seismic isolation?

Since the environment and functions of nuclear power plants are more complex than normal architecture and nuclear power plants require much higher safety and reliability than other projects, seismic isolation of nuclear power plants needs particular designs.

Does a three-dimensional isolation nuclear power plant containment structure respond to seismic waves?

From Table 15 and Table 16, it can be seen that under different seismic waves, the displacement response of the three-dimensional isolation nuclear power plant containment structure is much greater than that of the non-isolation structure.

How base isolation technology can improve the safety of nuclear power plants?

Base isolation technology can make the seismic design of nuclear power plants not stick to the level of design ground motion and implement standardized operation, so as to improve the overall reliability and safety of nuclear power plant.

Which countries have developed seismic isolation specifications for nuclear power plants?

Many countries including Japan, the United States and France have made relevant specifications for seismic isolation design of nuclear power plants, among which the specifications of Japan and the United States have developed for a long time and are mature.

How to design a nuclear power plant in isolation design?

In isolation design, it is necessary to focus on analyzing the site environment of the nuclear power plant containment structure and select seismic waves that are more in line with the actual environment to make the results of structural elastic-plastic time history analysis more accurate.

What is seismic isolation technology?

Over recent past decades, seismic isolation technology has significantly advanced and has been extensively employed in infrastructures , . Base isolation is a type of passive control that is an effective method for achieving a resilient structure.
