MD3309 and MD3310), "dated January 30, 2008.2.) Email, D. L. Filchner (PPL) to R. V Guzman (NRC), "Susquehanna Unit 1 Dryer Report Ready for Download from PPL File Transfer Center ", dated May 31, 2010.3.) Email, R. V. Guzman (NRC) to D. L. Filchner (PPL), "Susquehanna Unit 1 EPU Power Ascension, Review of Data Package re: Steam Dryer Performance at 107 and 110.5%", dated June 3, 2010.The purpose of this letter is to provide notification that Susquehanna Steam Electric Station (SSES) Unit 1 license conditions 2.C.(36)(a)3, 2.C.(36)(b)7, and 2.C.(36)(f), established in Reference 1, have been met.On May 31, 2010 PPL Susquehanna, LLC (PPL) submitted the SSES Unit 1 Steam Dryer Report for NRC evaluation of steam dryer performance (Reference

2) based on data collected at the 3.5% power ascension step corresponding to 110.5% CLTP, as required by license condition 2.C.(36)(a)(3).

NRC review of this information (Reference 3)concluded that ascension to the full EPU power level (3952 MWt) was acceptable.

Accordingly, license condition 2.C.(36)(a)3 has been met.Enclosure 1 contains the PPL proprietary version of "SSES Replacement Steam Dryer and Flow Induced Vibration Report -Unit 1 Start-Up 114% Power Test Plateau" which is the written evaluation of steam dryer performance.

This evaluation is based on data collected during SSES Unit 1 power ascension to the full Extended Power Uprate (EPU)operating conditions at 3952 MWt (114% CLTP), in accordance with SSES Unit 1 license condition 2.C.(36)(b)7. DocumentControl Desk PLA-6633 The evaluation of data collected demonstrates that the new SSES steam dryer design possesses sufficient structural margin to the steam dryer ASME endurance limit of 13,600 PSI for continued power operation at 3952 MWt and therefore license condition 2.C.(36)(b)7 has been met.The report also includes a summary of the results of piping and component walk down results. General vibration levels increased during power ascension as expected, and the overall response of piping and components remained within established criteria.Enclosure 2 contains the non-proprietary version of the "SSES Replacement Steam Dryer and Flow Induced Vibration Report -Unit 1 Start-Up 114% Power Test Plateau" evaluation results discussed above.Enclosure 3 provides the results of the steam dryer visual inspections conducted during the SSES Unit 1 16th Refueling and Inspection outage. These results meet the intent of SSES Unit 1 license condition 2.C.(36)f.

Additionally, SSES Unit 1 license condition 2.C.(36)(e) requires that visual inspections be conducted of all accessible, susceptible locations of the steam dryer. These future inspections will be performed in each of the next two SSES Unit 1 refueling outages in 2012 and 2014 in accordance with this license condition.

Summary This report provides a summary of the SSES Unit 1 replacement steam dryer monitoring instrumentation (Main Steam Line Strain Gage) and flow induced vibration (FIV)measurements at the targeted 114.0% CLTP test plateau (3952 MWth). This data was collected at the actual power levels and core flows indicated in Table 1: Table 1: Power/Core Flow Data Collection Conditions Test Point Thermal Power MWth Core Flow (Mlbm/hrl 1 3948 102.0 2 3948 99.8 3 3916 106.3 The main steam line (MSL) strain gage locations are documented in Reference

1. Plant data log sheets for each Table 1 test point is contained in Appendix A. The data log sheets provide a record of plant conditions at these power conditions.

The MSL strain gage data indicates that sufficient steam dryer margin (2)} to the ASME endurance limit of 13,600 PSI exists. This data supports and validates the final steam dryer stress assessment documented in Reference

2. The analysis of the piping accelerometer FIV data confirms that there is adequate margin{{{ (2)} } } to the ASME limits in the SSES main steam, feed water, extraction steam, and HPCI steam supply system piping. The reactor recirculation, RHR, and RWCU system piping also are within ASME limits.2.0 Main Steam Line Strain Gage Data Analysis 2.1 Power Spectral Density Figures 1 through 32 provide power spectral density (PSD) plots of MSL strain gage readings.

The level 1 and level 2 monitoring curves for each strain gage location are also plotted on Figures 1 through 24. 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 band-pass 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 data collected at the respective test points are identified in Tables 2, 3 and 4 below: Page 1 Table 2: PSD Notch Filter Specifications for 102.0 Mlbm/hr Data (Test Point 1)Table 3: PSD Notch Filter Specifications for 99.8 Mlbm/hr Data (Test Point 2)M{I* I Table 4: PSD Notch Filter Specifications for 106.3 Mlbm/hr Data (Test Point 3)+ 4 2)}} }-t 4+ 4 4 Page 2 A noise peak at approximately 136 HZ was noted during the primary system hydrostatic test prior to plant start-up. This is a condition where systems are pressurized, to operating levels but no steam flow exists. As Unit 1 ascended in power, this noise peak did not increase in proportion to the power increase. Minor random amplitude and frequency fluctuations were observed. The source of this noise could not be determined but it has been conclusively shown that it is not related to power and/or steam flow and therefore a filter has been applied to eliminate it.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 32.This method of data processing was used to provide the results in a format consistent with the processing used to develop the monitoring curves.There are also two monitoring (limit) 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 of the limit curves and how they are generated is included in Reference 3 and Reference

4. These monitoring curves provide guidance for evaluating the measured dryer response with respect to the structural analysis results.Table 5 below shows the maximum strain gage reading for 3948 MWth and 102 Mlbm/hr (Test Point 1) as a percent of monitoring limits generated in accordance with Reference 4 using a baseline data set from Unit 1 collected at 3850 MWth (110.5% CLTP) @ 99.4 Mlbm/hr. All values of strain were below the level 1 and level 2 monitoring limits. The data is plotted with the monitoring limits in Figures 1 through 8.Table 5: Maximum MSL Strain Gage Readings @ 3948 MWth and 102.0 Mlbm/hr Expressed as a Ratio of the Monitoring Limits (Test Point 1)Table 6 below shows the maximum strain gage reading for 3948 MWth and 99.8 Mlbm./hr (Test Point 2) as a percent of monitoring limits generated in accordance with Reference 4 using a baseline data set from Unit 1 collected at 3850 MWth @ 99.4 Mlbm/hr (114%CLTP). { {{Page 3

4. The results of that analysis are documented in Section 2.3 below and in Tables 8 through 10. {{{(2)}}}Page 4

2.2 Trending

For trending purposes, filtered MSL strain gage PSDs for powers up to 114.0% of CLTP (3952 MWth) have been plotted in a waterfall format and are presented in Figures 25 through 32. Figure 33 is a trend plot of the RMS value of the sample time histories plotted against total steam flow. Figures 25 through 33 show that MSL strains are M{ .12)}}}MSL strain gages mounted on the A and D steam lines have the highest magnitude readings. This is attributed to the 15 Hz peak being reinforced by the safety relief valve (SRV) dead-legs on these two steam lines, as discussed in References 5 and Reference 6.The Unit 1 MSL strain gage PSDs measured at 3948 MWth are similar to the PSDs measured on Unit 1 3733 MWth in frequency content and with the anticipated magnitude increase. Figures 34 through 41 show Unit 1 data plotted at 3733 MWth and 3948 MWth.An examination of Figures 34 through 41 demonstrates that the acoustic signatures are similar.2.3 Unit 1 Steam Dryer Stress Estimates As an additional analysis of the acoustic data generated by Unit 1, an F-Factor and RMS analyses (as described in Reference 3 and Reference

4) was conducted on a set of MSL strain gage data. This analyses generated estimates of dryer stresses at the current operating plateau. Data was taken on Unit 1 at Test Point 1 (3948 MWth and a core flow of 102 Mlbm/hr).As described in Reference 3 and Reference 4, three separate analyses were performed on the data set. Filtering of the data sets removed the recirculation system pump vane passing peaks. The results presented below exclude estimates of stresses that result from pump vane passing peaks. The effects of the vane passing peaks on total steam dryer stresses are discussed in Reference

2. Tables 8 through 10 contain the results of the analyses.Page 5 Table 8: Adjusted Stress with Bias and Uncertainty and LCF ACM Analysis F-Factor Method i 2)1 } }Table 9: Adjusted Stress with Bias and Uncertainty and LCF Supplemental Analysis F-Factor Method I.(2)} } }Page 6 Table 10: Adjusted Stress with Bias and Uncertainty and LCF Supplemental Analysis RMS Method++-I--I-+-1-(2)},}An examination of Tables 8 through 10 further demonstrates that {Template:(2)2.4 Steam Dryer Evaluation Summary The stress values presented in Tables 8 through 10 are bounded by the benchmarked stress and margin values contained in Table 7 of Reference 2 (Susquehanna Replacement Steam Dryer Updated Stress Analysis At Extended Power Uprate Conditions).

Based on the current margins indicated by the stress values in Tables 8 through 10 and in Figures 1 through 33, there is adequate projected margin {{{ (2)}}} to the steam dryer ASME endurance limit of 13,600 PSI for continued power operation at 3952 MWth.3.0 Piping Flow Induced Vibration 3.1 Introduction Piping accelerometers on the main steam, feed water, reactor recirculation, residual heat removal (RHR), reactor water cleanup (RWCU), extraction steam and HPCI piping systems were monitored during start-up. Key locations were selected based on geometry and the expected potential for vibration-related problems or maximum pipe stress. For main steam, the accelerometers were located on the "B" and "C" lines, since these are expected to be the most active. These steam lines have active flow under the SRV branch lines, as well as the HPCI and RCIC system steam supply branch connections. Accelerometers were also located at, or near, the above mentioned branch lines of interest. In all, 87 accelerometers at 36 locations were monitored during power ascension. Page 7 Prior to the start-up, two RMS acceptance levels were calculated for each accelerometer on the main steam, feed water, extraction steam, and HPCI piping systems. A level 1 value was determined based on vibration calculations using ASME OM-3 (Reference 7)allowable stresses. A level 2 value was conservatively established for each accelerometer at 80% of level 1. The accelerations used in the vibration analyses were "zero to peak" values (consistent with ASME OM-3) and conservative factors were used to determine equivalent RMS values.The Reactor Recirculation/RHR/RWCU system accelerometers were assigned only conservative level 2 RMS and "zero-to-peak" allowable values, since these systems were negligibly affected by EPU. If both criteria (i.e., RMS and "zero-to-peak") were exceeded for a given instrument, then a more detailed engineering evaluation was performed. 3.2 Data Collection Scope Data collection commenced with background data collection during the operational hydro before the Unit 1 was at power. Formal power ascension monitoring for the effects of FIV on piping initiated at the target test point of 2569 MWth (-65% full EPU power).Data was also collected and analyzed at targeted test points of 3293 MWth (OLTP), 3733 MWth (107% CLTP), 3864 MWth (- 10% CLTP) and for several core flow conditions at 3952 MWth (-114% CLTP), as described in Table 1 above. In addition, piping FIV was monitored on an hourly basis, and general plant walk downs were continuously performed during power ascension from 3733 MWth to 3864 MWth, as well as from 3864 MWth to 3952 MWth.Detailed plant walk downs of piping and components were performed for most systems affected by Extended Power Uprate located outside the drywell. These walk downs were performed at the targeted test points 3293 MWth, 3733 MWth, 3864 MWth, and 3952 MWth. The walk downs were performed for piping and components located in accessible and inaccessible (high radiation) areas. A remote controlled, mobile camera was used to observe the vibration in the inaccessible areas.3.3 Data Analysis Methodology Spectral analyses for each accelerometer were performed at each of the test points for a time period of 160 seconds. The data was evaluated based on 4 second blocks of data and to increase the number of spectral averages, the data blocks were overlapped by 50%.The data was band-pass filtered between 2 Hz and 250 Hz, with a 0.25 Hz bin size to provide for consistency with the method used to develop the acceptance criteria for the accelerometers. Significant electrical noise occurred on the extraction steam system piping at the 60 Hz multiples of the power supply frequencies. The application of notch filters was required.Multiples of the reactor recirculation pump vane passing frequency (VPF) were observed;however, the VPF frequencies were not filtered, since they represent true mechanical vibration (i.e., displacement/stress). Page 8

3.4 Results

Throughout power ascension no accelerometers degraded to the point where their output was judged to be questionable (i.e., a "near zero" output). Figures 42 through 44 indicate the percent of allowable RMS acceleration versus total main steam flow/feed water flow trends during the power ascension to 3952 MWth. In addition, Figures 45 through 49 indicate the percent of allowable RMS acceleration versus core flow trends for the Reactor Recirculation, RHR, and RWCU system instruments. The walk downs were performed for piping and components located in accessible and inaccessible (i.e., high radiation) areas. As expected, the vibration observed increased with power ascension. All observed vibration was within previously established acceptance criteria.At the 106.3 Mlbm/hr core flow (Test Point 3) one accelerometer on the Reactor Recirculation system and 2 accelerometers on the RHR system (see Figures 45 and 49)exceeded their conservative Level 2 RMS limits but were within the Zero-to-Peak pre-established Level 2 limits. This ensures that the ASME OM-3 allowable stresses for vibration were met.A second accelerometer on the Reactor Recirculation system exceeded both its Level 2 RMS allowable and its Level 2 Zero-to-Peak allowable values (see VE16730 on Figure 45). The increase in steam and feed water flows does not affect the Reactor Recirculation and RHR system piping vibration but Reactor core flow rates do directly affect vibration levels on these systems. There was no Level 1 piping vibration limits for these piping systems. A condition report in the Susquehanna corrective action program evaluated and tracked this condition. Condition Report 1270880 determined that the measured acceleration at this location resulted in stresses that were less than ASME OM-3 allowable.

3.5 Piping

Summary During the Unit 1 power ascension to 3952 MWth, piping vibration levels were monitored to assess effects of flow-induced vibration (FIV). Trending was performed, and all accelerations/displacements were within pre-established limits, based on ASME OM-3 allowable stresses with the exception of the one Reactor Recirculation instrument at a core flow of 106.3 Mlbm/hr mentioned above. After additional analysis, the measured acceleration at this location resulted in stresses that were less than ASME OM-3 allowable by 31%.The piping/components walks down results were as expected; general vibration levels increased during power ascension but the overall response of piping and components were within established criteria.Page 9 4.0

Summary of Results: The Unit 1 steam dryer was inspected in accordance with the requirements of BWRVIP-139 and recommendations from General Electric, the steam dryer manufacturer. The examination consisted of 406 separate welds and components with the following non-conforming conditions identified:

• Cracks were discovered in non-structural tack welds on all four lifting eye anti-rotation set screws. The tack weld cracks were functionally repaired by a modification in which additional weld metal was added between the lifting eye and lifting rod. These new welds have been included in the steam dryer inspection program and will be inspected during the next Unit 1 refueling outage." Three small cracks were discovered in the Heat Affected Zone (HAZ) of one drain channel weld. The cracks in the drain channel Heat Affected Zone were concluded to be Intergranular Stress Corrosion Cracking (IGSCC) and the disposition was use-as-is.

The drain channel IGSCC cracks will be inspected during the next Unit 1 refueling outage to determine if any crack growth has occurred.There were no other non-conforming conditions identified during the inspection process.This complete inspection scope will be repeated in each of the next two refueling outages (2012 and 2014). the inspection scope beyond these outages will consist of a sampling program.Inspection Methods Used: The VT-i visual examination was utilized to visually determine the condition of a part, component or surface and to reveal such conditions as cracks, wear, corrosion, erosion and/or physical damage to such parts, especially welded joints.The VT-3 visual examination was utilized to determine structural integrity, the measurement of clearances, detection of physical displacement, determination of the structural adequacy of supporting elements, the soundness of connections between load carrying structural members, and tightness of bolting.Inspection Results Identification: NRI -No Recordable Indication. The weld or component was in compliance with the inspection acceptance criteria, no cracks or deformation during inspection was discovered. No further actions were required.RI -Recordable Indication. The weld or component contained a defect such as a crack or deformation that resulted in further evaluation and disposition in the Corrective Action Program.Page 1 of 17 Unit 1 License Condition 2.C(36)(f) Steam Dryer Inspection Results DRYER 140-DEG LIFT ANCHOR WELDS 3/11/2010 vF-r-NRIJ .....Repair -Add additional weld material between lifting eye and lifting rod DRYER 140-DEG LIFTING EYE TACK WELDS Cracked tack weld 3/6/2010 VT-3 RI 1240628 DRYER 220-DEG LIFT ANCHOR WELDS DRYER 220-DEG LIFT ANCHOR WELDS 3/6/2010 VT-1 NRI 3/11/2010 VT-1 NRI Repair -Add additional weld material between lifting eye and lifting rod DRYER 220-DEG LIFTING EYE TACK WELDS DRYER 320-DEG LIFT.ANCHOR WELDS DRYER 320-DEG LIFT.ANCHO_9R WELDDS.3/6/2010 VT-3 RI Cracked tack weld 1239962..3/1-2/20-1.0 -I....N !RI.....NRI 3/14/2010 VTI-I................ .~ ~ ~~~............ ................. i Repair -Add additional weld material.between lifting eye d I and lifting.I.d rod DRYER 320-DEG LIFTING EYETACK WELDS 3/6/2010 VT-3 RI I IDRYER 40-DEG LIFT ANCHOR WELDS -P 311/ 1-1 NRI DRYER 40-DEG LIFTING I EYE TACK WELDS _ 3/9/2010 -VT-3 NRI _Crackec tack we 241230 Page 2 of 17 Unit 1 License Condition 2.C(36)(f) Steam Dryer Inspection Results Add additional weld material between lifting eye Cracked and lifting tack weld rod DRYER 40-DEG LIFTING EYE TACK WELDS DRYER COVER PLATE WELDS 270 DEG 3/13/2010 3/17/2010 VT-3 RI 1243888 VT-1 NRI DRYER COVER PLATE WELDS 90 DEG DRYER HOOD A 3/20/2010 VT-1 NRI 3/19/2010 Iv-r-3 INRI DRYER HOOD A 0 DEG HOOD SUPPORT 3/11/2010 VT-1 NRI DRYER HOOD A 0 DEG I HOOD SUPPORT 3/12/2010 VT-I .NRI .DRYER HOOD A 180 DEG HOOD SUPPORT 3/11/2010 VT-1 NRI ___DRYER HOOD A 180 DEG SEAM WELD I DRYER HOOD A 180 DEG SEAM WELD DRYER HOOD A DIVIDER 11PLATE .. 0 DEG DRYER HOOD A DIVIDER IPLATE 180 DEG DRYER HOOD A P6 PLUG DRYER HOOD A UPPER HORIZONTAL WELD DRYER HOOD B DRYER HOOD B 0 DEG HOOD SUPPORT DRYER HOOD B 0 DEG I SEAM WELD 3/9/2010 VT-1 NRI 3/11/2010 VT:ijNF~.3/1, 11/2-0-10 VT-i 3/11/2010 VT-i 3/16/2010 1 VT-3 NRI NRI NRI NRI 3/16/2010 3/21/20 10 3/11/2010 3/10/2010 VT-1 VT-3 VT-1 NRI NRI.......... ...VT-1 NRI DRYER HOOD B 180 DEG[HOOD SUPPORT I DRYER HOOD B 180 DEG..SEAM WELD 1 DRYER HOOD B CENTER S E A.M W E LD........................... ........................
