l-l I INTRODUCTION This report a srunmary of the Beaver Valley Unit 2 steam generator (SG) bobbin and probe inspections at tube $ryport plate (TSP) intersections from the Spring 2017, 2Rl9 outage, together with postulated Steam Line Break (SLB) leak rate and tube burst probability analyses. The 2Rl9 outage represenE the fourth application of the Generic Letter (GL) 95-05 (Reference l) voltage based repair criteria, snd implementation of its requirements, to the Beaver Valley Unit 2 Model 5lM SGs. The critsia were implemented during the 2Rl6 outage. Information requird by the GL 95-05 is provided in this report, including SLB leak rates and tube brust probabilities calculated using the end-of-cycle (EOC) conditions for the recently completed Cycle 19, re.presenting a condition monitoring assessment of bobbin coil sisnal arrplitudes for observed possible indications. In addition, a projection of EOC-20 bobbin coil volage disfiibutions, as well as the associated SG tube leak rates and burst probabilities through EOC-20 conditions is provided-The conditiou monitoring analysis at End-of-Cycle 19 (EOC-lg) was carried out using the actual bobbin coil voltage distributions measured during the 2Rl9 outage. These results show that the zRtg condition monitoring leak rates and conditional burst probabilities for all three SGs are well within their respective allowable limits. A comparison with the projections made in the previous 90-Day Report at the 2Rl8 outage (Reference 2) shows that the predictions were very conservative. These evaluations utilized the Westinghouse generic methodology that uses Monte Carlo analysis techniques (Reference 3). The operational assmsment analysis was performed to project leak rates and tube burst probahilities for postulated SLB conditions at the end of the upcoming cycle (EOC-20) based on the 2.0 volt repeir criteria for 7/8-inch diameter tubes. These analyses utilized bobbin voltage disnibutions measured during the recent (2R19) inspection and a growth rate distibution bounding the last trno irspections (2R18 and 2Rl9). Iak and burst qnelyses for the operational assessment were performed using the Reference 4 defrult value primary-to-secondary prcssure differential of 2560 psi" The Cycle 20 operational nssessment predicts that SG-B urill be the limiting SG for projected leakage. With a Cycle 20 period of operation estimated at 525 effective firll power days (EFPD), the limiting EOC-20 maximnm leak rate for SG-B is projected to be 0.220 H)m (room temperature), which is well below the allowable limit of 2.2 gpm for the faulted SG. The corresponding maximum tube burst probability for the limiting SG (SG.B) of 2.67 x l0-5 is well below the GL 95-05 limit of 1.0 x 102. Thus, the GL 95-05 requirements are predicted to be satisfied at the EOC-20. l +POINT is a tradentark of futec, Inc., in the llnited .Slates andlor olher counties.

2-l 2 STIMII{ARY AI{D CONCLUSIONS A total of 1098 distortd support indications (DSD in all three SGs combined were reported &ring the Beaver Valley Power Smtion Unit 2 (BVPS2) 2Rl9 bobbin coil inspection. Per GL 95-05, orly those DSI signals with a bobbin coil signal amplitude of 2.0 volts or greater are required to be i.spected using a +POINT (or equivalent) probe. AII DSI signals reported during 2Rl9 were less then 2.0 volts, so no indications were required to be tested with the +POINT probe. However, some indications were tested with the +POINT probe to confirm the minimal botrbin coil voltage grourth condition. These indications u/ere confirmed as axial outside diameter stress corrosion cracking (ODSCC) usine the +POINT probe during the 2Rl6 and have been inspected with a +POINT probe at each successive outage. In addition, in response to a prior Nuclear Regulatory Commission (NRC) question all DSIs greater than one (l) volt were inspected with a +POINT probe. The murimum bobbh coil volage indication in all three SGs was 1.45 volts on R2l C54 at the 02H tube support plate in SG-B. SLB leak rate and tube hurst probability analyses were performed using the actual 2Rl9 bobbin voltage distributions (condition monitoring analysis) as well as the projected EOC-20 bobbin voltage distributions (operational assessment). The SLB leak rates from the condition monitoring analysis show significant margins relative to the faulted SG allowable limit of 2.2 gpm (room temperature), Reference I l. The corresponding condition monitoring tube burst probability 2. values are well below the allowabte limit of I .0 x l0 At 2R19, the largest SLB leak rate in the condition monitoring analysis is calculatd for SGB, with a magnitude of 0.067 gpm, which is well below the allowahle SLB leakage limit of 2.2 Hlm in the faulted SG. All leak rate values Eroted are equivalent volumetric rates flt room temperaflre. The Iimitine conditional tube bunt probability from the condition monitoring analysis, l.44xl0'5 also predicted for SG-8, is well below the Nuclear Regulatory Commission (NRC) reportine guideline of 1.0 x l0-2. Thus, the condition monitoring results are well within the allowable limiilreporting guideline. SLB leak rate and tuhe burst probahility projections at the EOC-20 conditions were performed using the latest alternate repair criteria (ARC) database available for 7/8 inch outside diameter (OD) tubing (Addenduur 7 update), which is docrunented in Reference 4. Leak snd burst analyses for the Cycle 20 operational assessment were performed rsing the Reference 4 default primary+o-secondary pressure differential of 2560 psi. SG-B is predicted to be the limiting SG. For a projected Cycle 20 duration of 525 EFPD, the EOC-20 leak rate projected for SG-B using the GL 95-05 constant probability of detection (POD) of 0.6 is 0.220 H)m (at room temperature), which is less than the current limit of 2.2 g1)m in the faulted SG. This leak rate projection utilized the leak rate calculation methodology of References 5 and 6. The limiting EOC-20 burst probability of 2.67 x 105 is calculated for SG-B and is well below the allowable limit of 1.0 x l0-2. Therefore, all acceptance criteria of Reference I will be satisfied throughout Cycle 20. I SG.SGMP-17-21 July 2017 Revision 0
3-l 3 2RTg INSPECTION RESI]LTS AND VOLTAGE GROWTII RATES 3.1 2Rfg Inspection Results For outages prior to 2R16, the alternate repair criterion per GL 95-05 had been approved for BVPS2, but was not implemented. FirstEnergy Nuclear Operating Company (FENOC) had not implemented the criterion due to the small number of bobbin indications at TSP intersections which were confirmed to contain axial outside diameter stress corrosion cracking (ODSCC) using a +POINT probe. The criterion was implemented at 2Rl6 due to an increase in the number of DSIs confirmed to contain axial ODSCC from +POINT probe exaurination. It should he noted, for 2Rl6 and prior outages, the bobbin probe analysis utilized the guidance and requirements of GL 95-05. Since the initial 2Rl6 (and prior outages) inspection plan did not assume that GL 95-05 would be implemented, all bobbin coil DSIs were inspected using a +POINT probe. Note that under GL 95-05, only DSI signals with a 400/100 mix (hereafter referred to simply as the mix channel) signal amplirude of greater than 2.0 volts are required to be inspected using a +POINT probe. In accordance urith the guidance provided by GL 95-05, the 2Rl9 inspection of the Beaver Valley Unit 2 SGs consisted of a 100% eddy current (EC) bobbinprobe full length examination of the tube bundles in all three SGs. All hot and cold leg TSP intersections were inspected using 0.720 inch diarneter bobbin probes, with the exception of those hot leg TSP intersections in Rows 3 and 4 which contain SG tube sleeves at the hot leg top-of-tubesheet. In these two (2) tubes, a 0.630 inch diameter wide groove bobbin prohe was used for DSI detection. If a DSI was ohserved using the 0.630 inch wide groove bobbin probe, an attempt was made to obtain an inspection of these locations using a0.720 inch diameter bobbin probe from the cold leg side. tf this prohe could not pass over the U-bend, the tube was to be plugged as FENOC has not received NRC approval to utilize the reduced diameter probe results in the analysis. Prior evaluation of DSIs from other plants, which were inspected using both the 0.640 inch wide groove and 0.720 standard bobbin probe show that the voltage response from the 0.640 inch wide groove, is conservative comparedto the voltage response of the 0.720 inch staldflrdbobbin probe. A 0.630 diameter wide groove bobbin probe was used at 2Rl7 thru 2R19. The performance characteristics of the 0.630 and 0.640 inch wide groove probe were reviewed and confirmed to be consistent- During the 2R17 outage only one such indicatiotr was reported, and during the 2Rl8 and 2Rl9 outage Rone were reported using the 0.630 inch wide groove probe. To assess depth growth, the 2Rl8 DSIs with +POINT probe eonfirmation were also inspected at 2R19, even though none were required to be inspected with a +POINT probe due to the low bohbin amplitudes. This inspection showed little or no change in the +POtrNT probe signal character was observe{ thus implying little or no depth grourth of the indication. The largest
+POINT probe sigual amplitude in the 300 kHz channel from the confirmed DSI indications is only 0.2 volt, which represents a depth of 51% through-wall (TW) uslng the sizing protocol of Electric Power Research Instirute (EPRI) Examination Technique Specification Sheet (ETSS)
ETSS 128431. Long term Eending of the Unit 2 DSI population has shown a limited growth potential. For Cycles l0 through 19, the mean DSI voltage grorvth has been essentially zero. Additionally, the +POINT probe amplitrrdes for DSI signals confirmed as axial ODSCC have sG-sGMP-t7-2t Iuly 2017 Revision 0
3-2 been much less than 1.0 volt, suggesting that a shallow depth of penetration exists. This in turn suggests the DSI volage grourth will remain minimal and not move to "exteme" over the next operating cycle. Thus, it can be concluded that, the character of DSI indications reported to date has been associated with a depth of penetration well below 100% TItr In addition, the EOC-19 eddy current inspection plan included 100% +POINT probe inspectiou of all hot leg and cold leg dents >5 volts (as measured from the bobbin probe), which exceeds the GL 95-05 requirement for testing of said dents of dourn to the lowest cold leg TSP with DSI reports. The 2Rl9 eddy current inspection plan also included 100% +POINT probe inqpection of dents with indication (DNI) and 25% of support plate residuals (SPR). The DNI call can be generated by manual analysis or hy using a tertiary auto analysis. As can be seen in the table below, 1,223 total DNI indications were tested using RPC; however, neither P\ilSCC nor ODSCC was detected during any of these tests. SPRs are defined as bohbin coil signals which do not contain flaw-like compotrents but have a signal amplitude of >1.5 volts and phase angles >55 degrees. Axial ODSCC indications were not reported in these populations based on the +POINT probe analysis. No axial P1VSCC or circumferential stress corrosion eracking (SCC) was neported at any TSP intersection. The +POINT probe inspection program for den*, DMs, and SPRs was extensive. The follouring table provides the number of +POINT probe exams perfonned at TSP intersections during 2R19.

3-3 The requirements of the GL 95-05 methodology in Section l.b of Reference I are all satisfied. Tube intersections with the flow distribution baffle are exeluded from this GL 95-05 analysis. There are no other excluded tube support plate intersections (Reference 7). None of the indications included in this analysis were detected in dents >5.0 volts, as measured by bobbin. Atl SPR indications >2V were tested with the +POINT probe so that no ODSCC indications >1.0 volt would be missed or misread, as discussed earlier No copper signal interference was detected. Thbles 3-l through 3-3 present the 2Rl9 bobbin voltage data for the TSP intersections in the three SGs with distorted support indications (DSIs). A total of 1098 TSP locatious had DSI indications in all three SGs combined, of which only 19 indications had arnplitudes g[eater than 1.0 volt and no indications were greater than 1.5 volts. Note that the numeric value of the bin represents the upper range of the bin. That is, the 1.0 volt hiu contains DSI voltages from 0.91 to 1.00 volt- No DSI voltage exceeded the GL 95-05 lower volage repair limit of 2.0 volts. For 2R19, all DSIs with a voltage amplitude greater than or equal to 1.0 volt were automatically tested using +POINT probe, which exceeds the requirement by GL 95-05 to test all DSIs with a voltage amplitude greater thm or equal to 2.0 volts. Comparing the inspection results from 2Rl8 to 2R19, there were eight (8) new SAUMAI indications. Of those eight (8) new indications, none had a voltage arnplitude greater than or equal to 1.0 vslt. Tables 3-l through 3-3 tabulate the number of field bobbin indications, the number of those indications that were +POINT probe RPC inspected, the nurnber of +POINT probe RPC confimred indications, and the number of indications removed from service. No tubes were deplugged in the current inspection with the intent of retuming them to service after inspection in accordance with the alternate repair eriteria. The distribution of 2Rl9 indieations is alss shown in Figures 3-1 ,3-2, and 3-3 for SG-4" SG-B, and SG-C, respectively. The distribution of 2Rl9 indications as a function of support plate location is summarized in Table 3-4 and shown in Figure 3r4. The data show a strong predisposition of ODSCC to occur in the first few hst leg TSPs although the mechanism extended to higher TSPs. Only 17 indications were detected on the cold leg side; four (a) of these exceeded 0.5 volt, but do not exceed 0.75 volt. This distribution is consistent with that obsenred at other plants and is commonly attrihuted to the temperature dependence of ODSCC. Appendix A provides a listing of all DSIs reported at the BVPS 2R I 9 outage in the fonn of tables (Tables A-1, A-2, and A-3), rvhether axial ODSCC was confirmed (SAI/I{AI in Comment column), whether the tube containing the indication(s) was plugged (Comment column), and whether the indication was tested and no defect was found INDF in Comment column). 3.2 Voltage Growth Rates For projection of leak rates and tube burst prohabilities at EOC-20, voltage gpurth rates were developed from the 2R18 and 2R19 inqpection bobbin data. Grourth is determined when the same indication can be identified in nvo successive inspeetions. Since there can be new indications in one outage, the number of indications for which a growth can be defined is less than the number of indications detected- Table 34 shows a distribution of grourth as a function of TSP number. sG,sGMP-17-2t July 2017 Revision 0
3-4 Table 3-5 shows the frequency and cumulative probahility distrihution of grourth as a function of voltage change in each BYPSZ steam generator during Cycle 19 on a per EFPY basis. The average bobbin coil voltage grourth rates for each SG during Cycle 19 are grven in Tahle 3-6. The average grourth rates over the entire voltage range are negative indicating essentially no voltage growth. The Cycle 19 growth rates on an EFPY basis for each SC are shown in Figure 3-5. A magnification of the upper tail of this grourth distribution is shorrm in Figure 3-6. Also shown in Figure 3-5 and in Figure 3-6 is a flrrve which bounds all of the grouth curves for both Cycle 19 and Cycle l8 (Reference 2). Thble 3-7 lists the top 15 indications based on Cycle 19 growth rate in descending order. The average glourth rates over the entire voltage mnge for Cycle lg are negative indicating essentially no voltage grourth, but Table 3-7 shows that in cases of positive growth rates, that Cycle 19 had only modest grourth. The growth during Cycle 19 for all indications was under 0.5 volts. To determine if BVPS2 growth rates exhibitd a potential de,pendency on the BOC voltage, the growth rate data for Cycle 19 was plotted against BOC voltage, and the resulting plot is shown in Figrue 3-7. The Cycle 19 grourth daa do not show any tendency to increase with the BOC voltage; if at all, the grourth seertrs to decrease with increasing Bffi volt4ge. Thereforg grourth can be assumed independent of voltage in the Monte Carlo analysis for the operational assessment. 3J Prcbe Wear Criteria The probe wear criteria approved hy the NRC (Reference 8) was applied during the 2Rl9 inspection. When a prohe does not pass the lSols wear limit, this altemate criteria requires ttrat only tubes with indications ahove 75% of the repair limit inspected since the last successful probe wear check be r+inspected with a good probe. As the repair limit for Beaver Valley Unit 2 is 2 vole, all tubes containing indications for which the wom proh voltage is above 1.5 volts are to be inspected with a new probe. Since no indications had aurplinrdes over 1.5 vole no tubes were retested due to the probe we&r criteria being exceeded-3.4 NDE Uncertrinties The NDE uncertainties applied for the Cycle 19 voltage distributions in the Monte Carlo analyses for leak rate and burst probabilities are the same as those in the NRC Generic Lefier 95-05 (Reference U. The probe wear uncertainty has a strndard deviation of 7 .0% about a mean of zero and has a cut-offat 15% based on implementation of the probe wear standard. If the random sample of probe wear selected during the Monte Carlo simulations exceeds l5o/0, sampling of the probe wear distribution is continued until a value less than 15% is pickd. The analyst variability uncertainty has a standard deviation of 10.3% about a mear of zero with no cut-off. These nondestuctive examination [NDE) ucrtainty distributions are included in the Monte Carlo aualyses for SLB leak rates and tube burst probabilities based on the 2Rl9 acnral volage distrihutions as well as for the EOC-20 projections. sG-sGMP-t7-21 July 2017 Revision 0

4-l 4 IiATABASE APPLMD FOR LEAK AND BTIRTT CORRELATIONS 4.1 Thbe Material Properties The ruhe material properties are provided in Table 4- l of Reference 4 for 718-inch diameter tubes at 650"F. The parameters used in the analysis are the flow stress mean (sum of yield and ultimate sfiengths divided by 2) of 68.78 ksi and the flow stress standard deviation of 3.1725 ksi. 4.2 Burst Corrrclation The burst pressure, P5, is normalized to a material with a flow sffess of 68.78 ksi, which is the mean of the Westinghouse 7/8-inch tube data. The actual material propertry values for Beaver Valley Unit 2 we slightly higher than the average of all Westinghouse data. The correlation parameters shown in Table 4-l are taken from Reference 4. 43 Leak Rnte Correletion The steam line break pressure to be applied is 2560 psi unless a lower pressure can be justified. Therefore, the leak correlation for pressure of 2560 psi from Reference 4 is used for the leakage predictions. The parameters are shown in Thble 4-2. The leak rate criterion is given in terms of gallons per minute as condensed liquid at room temperature. 4.4 Pnobahility of Leak Correlation The probability of leak as a function of indication voltage is taken from Reference 4. The parameters are shown in Table 4-3. In the Monte Carlo analysis, leakage is quantified only if the indication is computed to be a leaker, based on the probability of leak correlation. 4.5 NDE Uncertainties The NDE uncertainties applied for the EOC-lg and EOC-20 voltage projections are described in Reference 1. The probe wear uncertsinty has a standard deviation of 7To about a mean of zero and has a cut-off at 15% based on implementation of the probe wear standard. The enalyst variability uncertainty has a standard deviation of 10.3% about a mean of zero with no cut-off. These NDE uncertainty distributions are used in the Monte Carlo analysis to predict the brrst probabilities and accideut leak rates at EOC-19 and EOC-20. The voltages reported were adjusted to account for differences between the laboratory standard and the standard used in the field. 4.6 Upper Voltage Repair Limit Per Table 5.4-20 of Reference 12, the BVPSZ Updated Final Safety Analysis Report (UFSAR), the pressurizer safety relief valves have a nominal setting of 2485 psig, or the Reactor Coolant System (RCS) design pressrue. Applying a 3% allowance for accumulation per Section 2 of I Attachment to GL 95-05, the applicahle SLB conditions pressure differential across the SG tubes is then 2560 psig, which is the traditional pressure differential used for prior GL 95-05 sG-sGMP-r7-2r July 2017 Revision 0
4-2 analyses. The upper voltage repair limit of 4.57 volts is based on the structural limit in lhble 4-1 for a pressure differential of 2560 psi with a safety factor of 1.4 applied to the differential pressure. The upper voltage repair limit considers the projected voltage gowth during the next cycle and NDE uncertainty. The maximum average percentage gowth rate as a percentage of BOC voltage values for any steam generator is seen from Thble 3-6 to be very small. According to Reference l, the mininurm growth adjustrnent is 30% per EFPY (43.2% per cycle for the bounding 525 EFPD Cycle 20). Therefore, the specific murimum growth value of 43.2% and 20o/o for NDE uncertainty was used to estimate the upper voltage repair limit. This results in an upper voltage repair limit of 7.51 / (l + 0.432 + 0.20):4.60 volts. No indications greater than this voltage were left in service; the largest DSI voltage reported at 2R I 9 was I .45 volts. The analysis takes no credit for power operated relief valve (PORV) actuation even though the power operated relief valves (PORVs), block valves, and associated testing programs have been shown to satisfu the requirements of GL 90-06, as indicated in the NRC Safety Evaluation Report dated May 15, 1995. Crediting the PORVs would effectively increase the upper voltage repair limit by limiting the maximum pressure differential during a postulated SLB event and would reduce the calculated SLB conditions by limiting the maximum pressure differential. Considering the inspection history of the BVPS2 SGs, it is unlikely that a bobbin coil DSI voltage of >4.5 volts will be observed within the BVPS2 SGs. sG-sGMP-t7-2t Iuly 2017 Revision 0

5-l 5 SLB AT,IALYSIS METHOI}S A Monte Carlo analysis technique is used to calculate the SLB leak rates and nrbe burst probabilities for both actual 2Rl9 and projected EOC-20 volage distributions. The Monte Carlo analysis accounts for parameter uncertainty. The analysis methodology is described in the Westinghouse generic methods report of Reference 4 as supplemented by References 5 and 6. The Monte Cado computer program used to implement this method is documented in Reference 9. Essentially the same methodology was applied to leak and burst qnalyses performed for the original Beaver Valley Unit I SCrs, Referenoe l0-In general, the methodology involves application of conelatiors for burst pressure, probability of leakage and leak rate to a measured or calculated EOC voltage distibution to estimate the likelihood of tube burst and primary-to-secondary leakage during a posf,rlated SLB event. Uncertainties associated udth burst pressure, leak rate probability and leak rate correlations parameters are e4plicitly included by sampling distributions for the parameter uncertainties through the Monte Carlo sampling prccess. NDE uncertainties are also included- The voltage distributions used in the leak and burst projetions for the next operating cycle are obained by applying growth data to the BOC disnibution. The probahility of detection (POD) used to generate the BOC voltage distibutions considers both detmtion uncertainty and the likely occrurence of new indications. Comparisons of projected EOC voltage distributions with acfual distributions after a cycle of operation for a number of plants have shown that the Monte Carlo analysis technique yields consenrative estimates for EOC voltage distribution as well as leak and burst results based on those distributions. sG-sGMP-17-2r July 2017 Revision 0
6-t 6 BOBBIN VOLTAGE DISTRIBUTIONS This section describes the input data usd to calculate EOC bobbin voltage distibutions and presents results of calculations to project EOC-20 voltage distributions. 6.1 Calculation of Voltage llistributions The analysis for EOC-20 voltage distribution starts with an initial voltage distribution which is projected to the end-of-rycle conditions based on the grourth rate and the anticipated cycle operating duration. The number of indications assumed in the analysis to project EOC voltage distributions, SLB leak rates and tube burst probabilities is obained hy adjusting the number of reported indications using a POD, which accounts for both the detection uneertainty and the development of new indications over the projection period- This is accomplished by using a probability of detection (POD) fuctor, which is defined as the ratio of the actual number of indications detected to toal number of indications present. A conservative value is assigned to POD based on historical data, and the value used herein is discussed in Section 6.2. The calculation of projected bobbin voltage frequency distribution is based on a net total number of indications retumed to service, defined as follows. Nro,nrs: N/ POD - N'"p";.u + N*pr,ggeu

There are no deplugged tubes returned to service at the beginnhg of Cycle 20 (BOC-20); therefore, Na.pm,"a : 0. Seven (7) tuhes with seven (7) indications at the TSPs were plugged, therefore, Nrq**a: These tubes were plugged for reasons other tlun the presence of the DSI signal. 2Rl9 7. RPC "no degradstion found" tItIDF) indications were included in establishing the BOC-20 indication distibutions shown in Table 6-1. During the Monte Carlo simulations, voltages for bins with several indications are selected by randomly sampling the volage bins. For a few higher voltage indications in each SG, each indication is considerd to be in a separate bin, and the actual indication voltage is utilized in the calculations.

6-2 The methodology used in the projection of EOC-20 bobbin volage frequency disributions is described in Reference 3, and it is essentially the same as that used in the original Beaver Valley Unit I SGs, Reference I0. 6.2 Probebility of lletection (POD) The Generic Letter 95-05 (Referenc.e l) requires the application of a constant POD value of 0.6 to define the BOC distribution for EOC volage projections unless an alternate POD is approved by the NRC. A POD value of 1.0 represents the ideal situation where all indications are detected. In this report the Reference I POD value of 0.6 is used for the EOC-20 projection. 63 Limiting Growth Rate llistribution As discussed in Section 3.2, the NRC guidelines in Generic Letter 95-05 stipulate that the more conservative growth rate distihutions from the past trro inspections should be utilized for projecting EOC distributions for the next cycle. For conserratisrn, a grourth rate cunre which bounded the growth rates of both cycles was used. Grourth distributious used in the Monte Carlo calculations are specified in the form of a histograrn, so no interpolation is performed between grourth bins. This assures that the largest grourth value in the distribution is utilized in the Monte Carlo simulations. 6.4 Cycle Operating Period The operating perids used in the grourth rate/EFPY calculations and voltage projections are a$ follows. Cycle 19 524.7 EFPD or 1.436 EFPY (actual) Cycle 20* 525 EFPD or 1.437 EFPY (projected)
*The crurent maximum fuel burn up that Cycle 20 is analyzed for is 517 EFPD 6.5 Prcjected EOC-20 Voltage Distribution Calculations for the EOC-20 bobbin voltage projections were perforrred for all three SGs hased on the 2Rl9 distributions shown in Table 6-1. The BOC-20 distributions were adusted to account for probabiliry of detection as described above, and the adjusted number of indications at BOG20 is also shown in Table 6-1. Calculations were performedusing a constant POD of 0.6 and 1,000,000 Monte Carlo rials. The distribution of indications at BOC-20 and the distribution of indications projected to EOC-20 are shown in Figures 6-1, 62, and 6-3 for SG-A, SG-B, ard SG-C, respectively. SG-B has the largest nurnber of indications at BOC-20. Reporting the maximum predicted voltage is not required by GL 95-05, but it is artitarily chosen to be the voltage where the integration of the upper tail of the voltage distribution reaches a 0.3 fractional indication.

7-l 7 SLB I,EAK RATE AND TUBE BTIRST PROBABILITY ANALYSES This section presents the results of the analyses carried out to predict leak rates and tube burst probabilities at the postulated SLB conditions using the actual voltage disrihutions ftom the 2Rl9 inspection (condition monitoring assessment) as well as for the projected EOC-20 voltage distributions (operational assessment). The methodology used in these analyses is described in Section 6. 7.1 2R19 Condition Monitoring Leak Rate and ltrbe Burst Prubability Analyses to calculate the 2Rl9 SLB leak rates and tr,rbe brust probabilities were perfonned using the actual bobbin voltage disrihutions presented in Tables 3-l to 3-3. The resule of the Monte Carlo calculations are sunmarized in Table 7-1. The SLB leak rates and tube burst probabilities, calculated using the actual measured 2Rl9 voltage distributions using 1,000,000 Monte Carlo trials, are shown in Thble 7- l. The methodology used for these calculations is documented iu WCAP-14277, Rev. l. The probability of leak, leak rate, ffid burst pressure correlations for 7/8 inch tubes presented iu the latest addendum to the EPRI Altemate Repair Criteria (ARC) Database, Reference 3, were used. The SLB primary-to-secondary pressure differential applied in the analysis is 2560 psi. The maximum 2Rl9 leak rate of 0.067 gpm and the maximum conditional burst probability of I.44 x l0'5 are well below their respective allowable limits (2.2 gpm per Reference ll, and 1.0 x 10-2 per Reference l, respectively). Therefore, the condition monitoring performance criteria are satisfied. 7.2 Cycle 20 Operational Asscasment L,eak Rate and Ttrbe Burst Prohability The SLB leak rate and tube burst probability projection for the Cycle 20 operational assessment was carried out usrng the latest update to the ARC database documented in Refuence 4, the POD of 0.60, and 1,000,000 Monte Carlo tials. The EOC-20 leak and burst analyses were performed using a primary-to-secondary presilre diffterential of 2560 psi, even though it is likely that PORV actuation will occur prior to the pressurizer safety relief valve lift seting. The EOC-20 projections, considering a 525 EFPD operation cycle, using POD : 0.6 are shown in Table 7-2. Both the maximum projected EOC-20 leak rate of 0.220 $)m and the manimum conditional burst probability of 2.67 x l0'5 are well below their respective allowable limits (2.2 gpmand 1.0 x l0'2, respectively). Therefore, the operational assessmentperformance criteria for the DSI indications are satisfied for Cyele 20. SG.SGMP.LT-21 July 2017 Revision 0

uNlT#2 -2R19 STEAM GENERATOR p (F STAR) REPORT Technical Specification 5.6.6.2.4 Equirs that a report be submitH b the Nudear Regulatory Commbsion (NRC) wilhin 90 days after the initial 6ntry into MODE 4 foilowing an outage in $fiich the F. (F Star) mBthodology was utilized during steam genorator (SG) inspeclions. For fte spring 2017 refueling 6utage (2R19), the inilial entry into MODE 4 occuned on inay 1@,2011. Per Tecfinical Specification 5.6.6.2.4, the follovying information is to be submittd to thE NRC: (a) Totel number of indications, loBtion of each indication, orientation of eaoh indication, sewrity of each indication, and whether the indications iniliatsd fom the inside or outsiie surface. This information can be found in Tables 2RCSSG21A, 2RCS-SG21B and 2RCS-SG2.lC. (b) The cumulative number of indications detected in the tubeshet reglon as e func{ion of eleveton within the tubesheet. This information can be found in Atlachmer A: "Unil 2 - cumulative Listing of Tubesheet lndicdions (All Outages)". (c) The projected end-of+l/cle accr'dant-induced leakago frcm tubesheet indicafions. This information can be found in the right-hand column of Tables 2RCSG2iA 2RCSG21B and 2RCSG21C. lt is also oelained in lEm 4 under lnformation for All Tables on page 3. Discussion: During 2R19, the Ptus Point probe wa8 utilized to inspect the top of tubesheet region in bottr the hot and cold legs. The 2R19 inspedion scope indudad 100 percent of the inservice hot leg tubes in all three SGs plus a tu/Bnty percent random sample of the insErvice cold leg tubes in 2RCSG21C. The inspectinn distance for either leg was from 6.0 inches above the top of trbesheet to 3.0 indres below the top of tubeshet. This inspedion dislance bounds the required F examination distance (that ie, the expanded porlion of the tube below the bottom of roll expansion transition) of 2.22 inches below the bottom of the mll expansion transition. Thero ar ten tubes looated on the hot leg side of the SGB that have roll expanslon transitions at lorrcr than nominal elevations. Th ten hot leg tubes with the deoper roll hansition locations were inspecled to a depth of S,O t1{eq ltoy the bp of tubesheet to ensurE thc F* dbtance was adequalely examined, ln the cold leg side or 2RCSG21C, there is one lube with a lorer than nominal roll bansition location. This tubB was not included in the 2R19 tlenty percent random sample in8pection because it was previously inspected in the 2R16 tu,enty prcent random samdg. The morphology for the majority of the indications being reported from the hot leg top of tubesheet region is believed to be oulside diameter stress @rro6ion cracking (ODSCC). This is bassd on sbnal nacognition and the location of the reported indications. Both axial and circumferentially orientated indications rvere ob3erved. Circ mferenthl indications located abovts the top of tubesheet remain bounded by thg expansion transilion. None ofthe indications that were reported during the 2R19 SG examinations represented a (Cycle 19) leakage potential at postulated main steam line braak (MSLB) conditions nor did the 2R19 indications cfiallenge th6 - structural integrity perfornance cdteria. The proJected accident induced leakage from all combined sources (steeves, plugs, indications left in-servioe under Generic Letler 95-05 and olher degradation within the tube bundle) remains well below the 2.2 gallons per minute (gpm) per SG allowed by the Technical Specifications. Page 2 of 12
The following information and Tables summarize the degradation observed during lhe 2R19 top of tubEsheet region examinations. lnformation for all Tables:
- 1) Elovation column: TSH - Top of tubesheet (Hd teg). 0.00" is located at the scondary aide tubesheel hce. A negativ measurement is the distance inb the tub$heEt ftom tho secondary side face. All other elevations ar above secondary side tubesheet Ece.
- 2) Orientalion column: SAI - Single axial indication; SCI/MCI - Single or multiple circumferential indications.
- 3) Severitv columns: Thie data hae been le-analyzed utilizing the Plus Point probe 3@ kHz channel. The 300 kHz channel providee the most ac@rate 3izing technique and is used fur assssing thc levcrity ofthe indications. The rsported arc leng fis are taken from the dda reaolulion proccas. Profile analyris shons these measuremenb to be generally conservatiro.
- 4) Prolec{ed EOC Leakaoe column: lndications reportod within th 3.O' (5.0'for particular tube locationa) ircpection distance belo lhe topof-tubsheet urer ither removEd frorn eervice via plugging or repaired with the Alloy 800 sleerre during 2R19. Th projec{ed end of cycle (EOC) accident induced leekage from indicetions lhat were rernored from service via plugging is consftlered zero. See Note I afler each tabls ior informatim on tubes wilh Bleeves installed.
- 5) For tubes w'th multiplo enhiss, th6 data represents (a) the individual crack data for multiple circumftrenthl indications (MCl's) or (b) the individual cmck data for mixed mode indications. Not all MCI'S aru lisbd with individual crack data as lhe profiling of theso indications for the percent of degraded area produced a value less than the condition moniloring limit even when the arc length for both flaws was summod as the totat arc length.
