I report was to derive the scaling spectra to predict EPU acoustic signature based on the CLTP plant data with the RSD dryer. The updated document eliminates sections that compared the two different dryer geometries and provides an in-depth review of the RSD subscale data analysis.2 The scaling spectra in Rev I version were calculated based on dynamic pressure See EDMS scaling which is a function of the velocity squared. The scaling spectra calculated based on the subscale testing are included in Rev 2 version.All of the figures were updated to reflect the 15 percent increase based on the mass flow rate increase, instead of power increase.The change bars were not included.WCAP-1725 1-NP August 2013 WCAP- 17251-NP August 2013 Revision 2 iii TABLE OF CONTENTS R E C O R D O F RE V ISIO N S ..........................................................................................................................

[]a.C 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
- 1. In order to evaluate the structural integrity of the steam dryer,]a In summer 2009, a four-line subscale model test was performed through a range of Mach numbers encompassing all planned operating conditions.
The main purpose of the four-line subscale model testing]a The subscale test data were evaluated to establish whether or not the plant is operating in an acoustically benign region through the range of planned operating conditions.
