Flow-induced piping vibration problems are common occurrences in power plants. Both nuclear and fossil plants experience similar types of vibration problems. However, most of the published results relate to nuclear plants.

In view of the large number of piping component and support failures reported in the literature due to flow-induced vibration problems, the lack of industry guidance and regulatory requirements on piping design to limit or reduce such vibration problems is a significant deficiency, one which requires prompt industry action. This bulletin, produced from the reports written under the grants PVRC 94-04 and 95-11 (Fluid Flow in Pipes), is intended to fulfill such a need.

This bulletin identifies the extent of industry problems and reveals the types of sources through an industry survey and a literature review. A list of references has been developed. Most of the useful references have been retrieved and reviewed. The abstracts of the references reviewed are compiled as an appendix and attached to the report (Appendix B) for easy reference by others. See more
