Description

A simple vibration model of a pressurized water reactor has been established and studied. It takes into account the effect of fluid-structure interaction on the coupled system pressure vessel - core barrel. The equations of motion are derived, and both the frequencies and the amplitude ratios of the natural system are calculated and discussed using the WWER-440 data. (author)
