Recording and Assessment of Structural Vibrations Recent Case Studies in Beznau NPP

摘要

The two presented case studies illustrate recent experience with the experimental approach to solve structural dynamic problems at the Beznau nuclear power plant. The experimetnal assessment of operational floor vibrations investigates the transfer path of the structural vibrations caused by the main steam line MSL and the feedwater line FWL. The measurements provide a data basis to assess equipment failures and to specify vibration requirements for new installations.
