1-1 1 BACKGROUND AND PURPOSE rad In order to uprate the plant power, the United States Nuclear Regulatory Commission (NRC) requires that the structural integrity of the steam dryer be evaluated with regard to possible acoustic pressure loads.
This requirement is detailed in Reference 2. In order to evaluate the structural integrity of the steam dryer,

Averaging was used, and the number of points selected for each ensemble were selected to yield a frequency resolution of 1 Hz (full scale). A Harming window was used to reduce spectral leakage, and 50 percent overlap was used to increase the number of averages.
