I report is 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.WCAP-1725 I-NP March 2013 Revision I iii TABLE OF CONTENTS RECORD OF REVISIONS

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 was to[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.
