102992-PPL-381591 -C-004 Non-proprietary Version 1.0 DISCUSSION This report provides a summary of the SSES Unit 1 flow induced vibration (FJV) monitoring program through 3733 Megawatt Thermal Power (MWth). 3733 MWt, is 94.4% of the licensed Extended Power Uprate (EPU) power level and 113.4% of the Original Licensed Thermal Power (OLTP) level. Section 2 presents the results of the Main Steam Line (MSL) strain gage monitoring program. Section 3 provides the results of the piping and components flow induced vibration monitoring program.

The locations of MSL strain gages are contained in References 1 and 2. A summary of test conditions along with pertinent plant data during the test are summarized in Appendix A.

Section 2.1 presents those results and compares them to the Level 1 and Level 2 monitoring curves contained in Reference 3. MSIV slow closures were performed to simulate steam flows at the full EPU power level. A benchmark MSIV closure case also was performed to simulate steam flows at the 3733 MWth power level. The results from the MSIV closure tests are presented below in Section 2.2. MSL strains were also recorded at varying core flows to determine the effects of recirculation flow and associated pump speed on piping accelerations and strains. The results of the core flow sweep testing are presented in Section 2.3.

Piping vibration levels were monitored to assure that the effects of FIV would not result in unacceptable wear and degradation of plant piping and components. Except for lower power levels (<50%), piping acceleration data was collected at the same test points as when MSL strain gauge data was obtained. Instrumented data from a total of eighty-four (84) accelerometers at thirty-six (36) locations were collected and analyzed. The systems monitored by this remote instrumentation were main steam, feedwater, reactor recirculation, residual heat removal (RHR), and extraction steam.

In addition to fixed monitoring, the vibration test plan also included local monitoring and plant walk downs at key points during the power ascension evolution. Walk downs of piping and components were performed to monitor F1V for systems affected by Extended Power Uprate that were located outside the drywell. Systems which were monitored with local instruments or via walk downs included condensate, high pressure coolant injection (HPCI) steam supply, feedwater, extraction steam, main steam, electro-hydraulic control (EHC), and the feedwater heater drains. Section 3.1 presents those results and compares them to pre-determined Level 1 and Level 2 acceptance criteria.

The piping and component FIV results from the MSIV closure tests are presented below in Section 3.2. Vibration levels were also trended at varying core flows to determine the effects of the recirculation pump speed (i.e., vane passing frequency) on piping and component vibration. The results of the core flow sweep testing are presented in Section 3.3.

102992-PPL-38159 1-C-004 Non-proprietary Version 2.0 MAIN STEAM LINE STRAIN GAGES 2.1 Start-up Data The MSL strain gages were monitored for increasing pressure fluctuations in the steam lines above 3489 MWth. Figures 1 through 16 provide power spectral density (PSD) plots for the MSL strain gages at the previous licensed thermal power level (3489 MWth ) and 3733 MWth.

There are four strain gages installed at each piping location spaced around the circumference of the pipe approximately 90' apart. The four strain gage readings were summed and averaged to form a virtual strain gage at that pipe location. PSD plots represent average values for a time period of approximately 3 minutes. A data sample rate of 2500 Hertz (HZ) was used in the data processing. The test data was band pass filtered between 2 and 250 HZ. There was significant electrical noise at 60 HZ, 180 HZ and the recirculation pump motor frequency.

Piping accelerometers also indicated the presence of a significant mechanical vibration at recirculation pump vane passing frequencies. Notch filters were applied at these frequencies.

Tables 1 and 2 provide a list of the notch frequencies applied. The PSDs were calculated using a Hanning window and a 0.5-HZ bin size.

102992-PPL-381591 -C-004 Non-proprietary Version criteria. Data from the instrumented steam dryer and the benchmarked structural analysis will be used to re-establish the MSL limit curves. The re-established limit curves will be used as acceptance criteria of subsequent power ascensions.

Reviews of Figures 1 through 16 indicate that measured MSL strains remained below the Level 1 monitoring curve except for two occurrences. MSL B upper strain gage exceeded the Level 1 curve at approximately 230 HZ (See Figure 5). And the MSL D upper strain gage exceeded the Level 1 curve at approximately 31 HZ (See Figure 14). In both cases, a slight frequency shift would have brought the measured strain back under the Level 1 curve.

2.2 MSIV Slow Closure Tests The design basis pressure loading used in the steam dryer structural analysis was developed using MSL pressure data (derived from MSL strain) for the 3733 MWth power condition. The 3733 MWth steam flows in each steam line were simulated by slowly closing one MSIV at a lower power level (2873 MWth) and forcing steam through the remaining three steam lines at flow rates equivalent to 3733 MWth. The purpose of the testing was to benchmark the MSL pressure data resulting from the MSIV closures against the MSL pressures with all four MSIVs open at 3733 MWth. MSL strain gage readings for the steam lines opposite the closed MSIV are plotted against data from 3733 MWth with all four MSIVs open. This data is presented in Figures 17 through 24.

The strain gage data was processed as described in Section 2.1 above. Notch filters were applied to the 3733 MWth data as described in Table 2 above. Notch filters for the MSIV closure cases were as described in Table 3 below:

The MSIV closures were repeated at a higher power level to simulate full EPU steam flow (3952 MWth) in each main steam line. The closures were performed at 3039 MWth. The strain gage data was processed as described in Section 2.1 above. Notch filters for the MSIV closure cases were as described in Table 4 below:

The Level 1 and Level 2 monitoring curves were plotted against the 3039 MWth MSIV closure data. The data from these MSIV closures is presented in Figures 25 through 40. A review of these figures demonstrates that no new frequency content occurred at full EPU steam flows and the strains grew at a predictable rate. Most of the data taken at the simulated full EPU power level was below the Level 1 limit curve. There were four (4) of instances where the Level 1 curve was exceeded. See Figures 26, 28, 29 and 38. As stated previously, these curves were not used as test acceptance criteria. Data from the instrumented steam dryer and the benchmarked structural analysis will be used to re-establish the MSL limit curves. The re-established limit curves will be used as acceptance criteria of subsequent power ascensions.

2.3 Core Flow Sweeps The purpose of the increased core flow sweeps was to determine the effect of mechanical vibration induced by the reactor recirculation pump vane passing pulses on the MSL strain gages.

The core flow sweep test was comprised of fifteen (15) step increases in core flow. These were started at 100 Mlbs/hr and 3535 MWth and finished at 108 Mlbs/hr and 3723 MWth.

Since power increases with core flow, the initial plant power was adjusted to target 3733 MWth at the end of the sweep test. Previous plant testing has shown that maximum plant vibration occurred above 103 Mlbs/hr.

The data was processed as described in Section 2.1. For each sweep point the vane passing frequency (VPF) was calculated and the RMS Fourier coefficient for the VPF and two times the VPF were plotted. These plots are shown in Figures 41 and 42. Figure 41 shows a secondary VPF peak at approximately 105 Mlbs/hr and a primary VPF peak at 107 Mlbs/hr.

((

See Section 1.4 and Figure 21 of GE-NE-0000-0085-2413-P- RO.) Figure 42 shows the RMS value of the 2 X VPF Fourier coefficients. The 2 X VPF response is relatively flat with respect to core flow.

102992-PPL-381591 -C-004 Non-proprietary Version 2.4 Summary The MSL strain gage data exhibited expected frequency content and magnitudes. No unexpected frequencies were observed at 3733 MWth and during the MSIV closure tests to simulate full EPU steam flows. The Level 1 and Level 2 monitoring curves were adequate with four exceptions. See Figures 26, 28, 29 and 38. Revision to the curves is warranted before they can be used as acceptance MSL limit curves. Data from the instrumented steam dryer and the benchmarked structural analysis will be used to re-establish the MSL limit curves. The core flow sweeps did show that there was a MSL strain component at vane passing frequency and at two times vane passing frequency. The VPF magnitudes peaked at approximately 107 Mlbs/hr of core flow. (Note: The MSL data peaked at approximately 107 Mlbs/hr. The steam dryer data peaked at 105 Mlbs/hr.)

3.0 PIPING VIBRATION 3.1 Start-Up Data The piping accelerometers were monitored for vibration changes at fourteen (14) different power levels from 583 MWth to 3733 MWth. A second set of data was taken at fifteen (15) different reactor core flows from 91 Mlbs/hr to 108 Mlbs/hr. Accelerometers were located on the main steam, feedwater, reactor recirculation, residual heat removal (RHR), reactor water cleanup (RWCU) and extraction steam at key locations 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 relief valve branch lines, as well as the HPCI and RCIC branch connections. In addition, accelerometers were also located at, or near, these branch lines of interest.

A spectral analysis was performed for each of the test points for time periods of approximately 3 minutes. A data sample rate of 2048 Hz was used in the data processing. Filtering at 60 Hz was used only in the extraction steam lines, as there was no significant electrical noise at 60 Hz, 120 Hz, or 180 Hz at the other accelerometer locations. The spectral analyses were calculated using a 2 HZ to 250 HZ band pass filter and a 0.25 Hz bin size. Piping accelerometers indicated the presence of a mechanical vibration at the recirculation pump vane passing frequencies. Figure 43 shows the unfiltered response for accelerometers located on the "C" main steam line and illustrates this response at the 118 HZ to 119 Hz range. This figure also demonstrates that there are no significant peaks where the notch filters were applied to the MSL strain gage plots. This response is typical of steam line piping mounted accelerometers.

Prior to the start-up, two RMS (Root Mean Square) acceptance levels were calculated for each accelerometer. A Level 1 value was determined based on vibration calculations using ASME OM-3 (see reference 4) allowable stresses; a Level 2 value was simply designated as 50% of Page 11 of 68

102992-PPL-381591 -C-004 Non-proprietary Version 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.

Figures 44 through 46 show the percent of allowable RMS acceleration versus total main steam flow/feed water flow trends during the power increase.

Only 1 accelerometer, on the main steam line B exceeded its Level 2 value (see Figure 44).

This first occurred at the 3733 MWth power level and remained above its Level 2 value during the subsequent core flow tests. The acceleration plotted on Figures 44 and 45 to the right of the 3733 MWth line (Unit l's first phase EPU), are taken from the MSIV slow closure tests that simulated the individual main steam line flow that is expected when at 3952 MWth (full EPU).

Walk downs of piping and components were used to monitor Flow Induced Vibration (FIV) for most systems affected by Extended Power Uprate that were located outside the drywell. These walk downs were performed at the 75% CLTP (65% CPPU), 100% CLTP (83.3% CPPU),

103.5% CLTP (91.3% CPPU), and 107% CLTP (94.4% CPPU) power levels. 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. Experienced piping engineers performed the observations of both the accessible and inaccessible areas. As expected, the general vibration observed increased with power ascension. All observed vibration was within previously established acceptance criteria.

The walk down of the main steam HPCI steam supply to the HPCI turbine observed vibration that warranted additional instrumentation. A tri-axial accelerometer was added at the maximum point of vibration. Preliminary screening of the measured accelerations exceeded the conservative Level 2 acceptance criteria but more detailed computer analysis showed that the maximum vibration was only 41% of the allowable value using ASME-OM3.

3.2 MSIV Slow Closure Tests The EPU effects on piping vibration at the full EPU power level (3952 MWth) were simulated in each main steam line by isolating each line one at a time thus forcing the total steam flow through remaining three lines. These tests were performed at approximately 3039 MWth, to simulate the full 3952 MWth EPU conditions. This data is presented in Figures 44 and 45 (to the right of the 3733 MWth line) for the main steam line piping accelerometers. During these tests, vibration levels on the reactor recirculation system and feedwater systems did not exhibit a significant change when a main steam line was isolated.

3.3 Core Flow Sweeps Figures 47 through 49 show the RMS acceleration trends on the main steam and feedwater during the core flow sweep from 100 Mlbs/hr to 108 Mlbs/hr. Before the core flow tests (see Figure 46) we see that the feed water accelerations are less than 10% of the allowable.

However during the core flow tests they reach values of - 38% and 23% of allowable (see Page 12 of 68

102992-PPL-381591 -C-004 Non-proprietary Version Figure 49). This indicates that higher feedwater flow rates at higher power levels reached by EPU have very little effect on the feedwater system but increased recirculation system flows do. The higher recirculation pump speeds, associated with increased core flows, cause increased vibration through the reactor vessel and platform structures and are measured in the feedwater piping that is attached to each. The higher vibration levels are acceptable because as previously stated they are below allowable levels. The same effects occur on the main steam line C to a lesser extent and even less on main steam line B.

PPL recorded and analyzed the Recirculation and attached Residual Heat Removal (RHR) and Reactor Water Cleanup (RWCU) piping accelerometer data during the EPU power ascension and during the core flow tests. These systems were not affected significantly during the EPU power ascension but were during the increased core flow testing. This was expected since the increased core flow requires increased recirculation pump speeds and previous core flow tests at pre-EPU power levels showed elevated acceleration responses at increased core flows.

Two accelerometers, one on the "A" RHR LPCI injection gate valve (HV151FO15A) and one on the injection drag valve (HV15 1FO17A) operators, exceeded their Level 2 initial RMS acceptance criteria. However, the detailed analyses showed that the "Zero to Peak" recorded accelerations were within the allowables. The RMS values were established based on a method that was more conservative than experienced during the testing.

3.4 Summary During the Unit 1 power ascension to 3733 MWth, piping vibration levels were monitored to assess effects of flow induced vibration (FIV). The data collected during MSIV slow closure tests simulated the 3733 MWth and the full 3952 MWth EPU conditions. Three locations exceeded the conservative Level 2 values. These locations were analyzed for their specific piping geometry and found within allowables. The trend plots indicate that the accelerations at full EPU conditions will be within allowable values.

The core flow sweep test results showed that the main steam, feedwater, extraction steam, and HPCI steam supply systems are within their allowables and projected to be so at full EPU. The acceleration results for the Recirculation/RHR/RWCU were within allowable.

Walk downs of piping and components were used to monitor Flow Induced Vibration (FIV) for most systems affected by Extended Power Uprate that were located outside the drywell. As expected, the general vibration observed increased with power ascension but all observations were within previously established acceptance criteria.
