Seismic Response Analysis

Aiming at the nuclear power plant structure and adopting time domain analysis approach, the seismic analysis of an intake tunnel for nuclear power plant is performed with FLAC3D in this paper. Contraposing the characters of the field rock of the nuclear plant, the internal force distribution of the tunnel under different wall rocks is researched and analysed, and the envelope diagram of inner force in the lining of the tunnel is drawn. The obtained law can provide the basis for the seismic response analysis of tunnels.

The reactor coolant pump in nuclear power plant is the only revolving equipment in the nuclear power plant. Its functional stability will directly affect the security of nuclear power plant. The coolant pump of a very nuclear plant is examined by using response spectrum analysis to analysis dynamic characteristics and responses aiming at finding the natural frequencies of vibration, modes of vibration and seismic responses, and any possible step which may cause damage of the whole system. The favorable spectrum and unfavorable one are investigated as well. The paper focuses on avoiding the detrimental effects caused by earthquakes, therefore may lay down a theoretical foundation for structural design and installation.

In this paper, the behavior of the structure of a pressurized water reactor (PWR) nuclear power plant (NPP) in China, is taken into consideration during a great earthquake especially beyond the design benchmark. The effects of earthquake energy absorption are analyzed using simplified multi-lumped mass system. The effects of site conditions, post yield stiffness, yield force on isolated reactor structure (IRS) are also discussed. The results show that isolation technology can significantly reduce seismic response of the reactor structure and achieve preferable earthquake energy absorption of the IRS beyond the design benchmark during a great earthquake. Earthquake wave characteristics and isolation layer parameters have direct effects on seismic response and the results of parameter analysis can provide reference for a correct and logical design of IRS.
