Abstract

The assembly system consisting of the keyed graphite components, which is employed in the core bottom structure of the HTTR (High Temperature Engineering Test Reactor), has a nonlinear vibrational characteristic. The analytical code was developed to predict the vibrational characteristic, and the validity of the code was verified through seismic model tests.
