Flow-induced vibrations can have devastating consequences. For example, the Tacoma Narrows Bridge in Washington collapsed when strong winds induced vibrations that matched the natural frequency of the bridge. In California, Edison International decided to permanently shut down the nearly new San Onofre Nuclear Generating Station after vibrations in the steam generator caused alloy tubes to rub against each other, resulting in leakage and unsafe operating conditions.

As the world was second-guessing nuclear power, victims, the media, and researchers alike turned to an institution on the forefront of researching the increased dependability and safety of nuclear power: Oregon State University.
