A fast reactor core consists of hundreds of core elements, which lengthen due to thermal expansion and swelling. So, the core elements are self-standing on the core support structure and not restrained in the axial direction. The authors carried out vibration tests and verification of analysis code (REVIAN-3) to evaluate 3D core vibration behavior. This report describes the summary of some experimental results and analysis.
