- Abstract
- The SMART (System-integrated Modular Advanced ReacTor) is an integral-type small modular reactordeveloped by KAERI (Korea Atomic Energy Research Institute). This paper discusses the feasibility andapplicability of a 3D-based equivalent model using dynamic condensation method for seismic analysis ofa SMART control rod drive mechanism. The equivalent model is utilized for complicated seismic analysisduring the design of the SMART. While the 1D-based beamemass equivalent model is widely used in thenuclear industry for its calculation efficiency, the 3D-based equivalent model is suggested for the seismicanalysis of SMART to enhance the analysis accuracy of the 1D-based equivalent model while maintainingits analysis efficiency. To verify the suggested model, acceleration response spectra from seismic analysisbased on the 3D-based equivalent model are compared to those from the 1D-based beamemassequivalent model and experiments. The accuracy and efficiency of the dynamic condensation methodare investigated by comparison to analysis results based on the conventional modeling methodologyused for seismic analysis
