Flow Induced Vibrations for Reactor Internals of PWR : Less Art, More Science

摘要

This paper aims at illustrating the most salient features of FIV related problems for PWR internals, with an emphasis on Core Support structures vibrations. After having reviewed the possible approaches, from historical to current practices, and from most simple to more sophisticated, the basic ingredients to a meaningful analysis are recognized. Key assumptions and validity are also discussed. Ways and means for desirable advances are listed for more versatile and predictive FIV analysis tools development.
