The Research of Seismic Response Analysis of CARR Reactor Complex

摘要

CARR reactor complex includes core vessel, heavy water tank, flow guiding tank, decay tank and reactor pool, etc. There is a lot of light water and heavy water in the complex. A fluid-structure interaction must be simulated in the seismic analysis. The reactor complex is simplified a 3D fluid-solid coupled model which includes fluid elements and solid elements. A modal analysis is performed for the 3D fluid-solid coupled model and obtains natural frequencies and mode shapes under fluid-structure interaction. On the base an equivalent fluid-solid coupled model is built and performed for seismic response analysis.
