Vibration from flow-noise fluctuations and the 0.325 Alert level has resulted in early,                 early, costly and unnecessary RHR pump motor testing and replacement. For example, the testing frequency for RHR pump A motor was doubled in                                              replacement in 2007 in 2005 resulting in a replacement as a corrective action for the several  several instances of flow-noise        induced fluctuations above the flow-noise induced 0.325 Alert level.
