Title: Measurement and reduction of flow-induced vibration of a fuel element and rig in the HIFAR reactor.
Authors: Holland, PG
Issue Date: May-1975
Publisher: Australian Nuclear Science and Technology Organisation
Abstract: Flow-induced vibrations in the fuel element assembly of a research reactor were monitored and it was established that long-term monitoring of liner plug vibration can be used to indicate the mechanical integrity of a fuel element if a sufficient case history is established. The vibrational behaviour of a number if fuel elements with different integral modifications were examined but only a relatively small change in vibration levels was obtained. The overall vibration levels were most effectively decreased by installing flow straighteners in the exit nozzles of the plenum chamber.
