CONFIDENTIAL INFORMATION SUBMITTED UNDER 10 C.F.R. U2.390 AFFIDAVIT OF RICHARD D. PAGODIN I, Richard D. Pagodin General Manager-Nuclear Engineering PPL Susquehanna, LLC, do hereby affirm and state:

1. I am authorized to execute this affidavit on behalf of PPL Susque-hanna, LLC (hereinafter referred to as "PPL").

2. PPL requests that the information attached and identified by text inside triple brackets (({This sentence is an example.)}) be withheld from public disclosure under the provisions of 10 C.F.R. 2.390(a)(4).

3. The PPL Documents contain confidential commercial information, the disclosure of which would adversely affect PPL.

4. This information has been held in confidence by PPL. To the extent that PPL has shared this information with others, it has done so on a confidential basis.

5. PPL customarily keeps such information in confidence and there is a rational basis for holding such information in confidence.

The information is not available from public sources and could not be gathered readily from other publicly available information.

6. Public disclosure of this information would cause substantial harm to the competitive position of PPL, because such information has significant commercial value to PPL.

7.

The information identified in paragraph (2) above is classified as proprietary because it details the results of test data derived from test instrumentation installed specifically to collect this data. This instrumentation was installed at a significant cost to PPL. The data and the conditions under which it was collected constitute a major PPL asset.

8.

Public disclosure of the information sought to be withheld is likely to cause substantial harm to PPL by foreclosing or reducing the availability of profit-making opportunities. The information is of value to other BWR Licensee's and would support evaluations and analyses associated with extended power uprate license amendment submittals. Making this information available to other BWR Licensee's would represent a windfall and deprive PPL the opportunity to recover a portion of its large investment in the test instrumentation from which this data is derived. -4, PPL SUSQUEHANNA, LLC Richard D.

PPL Susquehanna LLC This report provides a summary of the SSES Unit, 2 replacement steam dryer monitoring instrumentation (Main Steam Line Strain Gage) 'measurements at the 103.5% CLTP test plateau. This data was collected at a power level of 3610 MWth and a core flow of 99.35 M lbm/hr. The main steam line (MSL) strain gage locations are documented in Reference

1. Plant data log sheet for each power step from 3489 MWth to 3610 MWth is contained in Appendix A.

The data log sheets provide a record of plant conditions during the power ascension. Figures 1 through 8 provide power spectral density (PSD) plots of MSL strain gage readings. The Level 1 and Level 2 acceptance curves for each strain gage location are also plotted on each figure. The strain values represent average strain values observed over a 180 second test time period. A data sampling rate of 2500 Hz was used in the data processing. The test data was bandpass filtered between 3 and 250 Hz to be consistent with the load definition used in the replacement dryer structural analysis in Reference 2. There is substantial noise from the 60 Hz alternating current and the recirculation pump power supply, thus filtering of this electrical noise was performed. Also the reactor recirculation pump vane passing frequencies were filtered from the data sets. Testing on the instrumented Unit 1 steam dryer { { { (2)} } } Reference 2 documented that the { (( (2)}}} The filters applied to the 3610 MWth data are contained in Table 1 below: Table 1: PSD Notch Filter Specifications Frequency I Width Origin 4- + i + t + (2)}}} Page 2 of 22

9 PPL Susquehanna LLC PSDs were calculated on 2 second blocks of data from the test time period (180 seconds). In order to increase the number of spectral averages, the data blocks were overlapped by 50%. The PSDs were calculated using a Hanning window and a 0.5 Hz bin size. The resulting PSDs were then linearly averaged and are presented as Figures 1 through 8. This method of data processing was used to provide the results in a format consistent iwith the processing used to develop the monitoring curves. There are also two monitoring curves included with the PSD plots. The Level 1 monitoring curve represents the response of the SSES dryer finite element (FE) model under the design acoustic load conditions factored by the minimum component analysis margin to the endurance limit. The Level 2 monitoring curve is based on 80% of the Level 1 curve. A more complete description is included in Reference 3 and Reference 4. The Limit Curves were generated in accordance with Reference 3 using a baseline data set from Unit 2 collected at 3489 MWth (CLTP). These monitoring curves provide guidance for evaluating the measured dryer response with respect to the structural analysis results and represent the acceptance criteria for the power ascension. Table 2 below shows the maximum strain gage reading as a percent of acceptance limits generated in accordance with Reference 3 using a baseline data set from Unit 2 collected at 3489 MWth (CLTP). All values of strain are below the Level 1 and Level 2 acceptance limits. Table 2: Maximum MSL Strain Gage Readings @ 3610 MWth Expressed as a Ratio of the Acceptance Limits (2) } } For trending purposes, filtered MSL strain gage PSDs for powers up to 103.5% of CLTP (3610 MWth) have been plotted in a waterfall format and are presented in Figures 9 through 16. Figure 17 is a trend plot of the RMS value of the sample time histories plotted against total steam flow. Figures 9 through 17 shows that MSL stress are { { { (2) } } MSL strain gages mounted on the A and D steam lines have the highest magnitude readings. This is attributed to the large 15 HZ peak being generated by the SRV dead-legs on these two steam lines. The magnitude and frequency of the MSL strain gage PSDs is similar to the PSDs measured on Unit 1 in 2008 in both frequency content and magnitude. Page 3 of 22

PPL Susquehanna LLC Summary Based on the current margin to dryer acceptance limits shown in Table 1 and in Figures 1 through 8, there is adequate projected margin to the dryer acceptance limits for continued power ascension to 3733 MWth.
