+POINT' 1 probe inspections at tube support plate (TSP) intersections from the Fall 2020, U2R3 outage, together with postulated Steam Line Break (SLB) leak rate and tube burst probability analyses. The U2R3 outage represents the first application of the Generic Letter (GL) 95-05 (Reference 1) voltage-based repair criteria, and implementation of its requirements, to the Watts Bar Unit 2 SGs. Information required by the GL 95-05 and by WBN Technical Specification 5.9.9 is provided in this report, including steam line break (SLB) leak rates and tube burst probabilities calculated using the end-of-cycle (EOC) conditions for the recently completed Cycle 3, representing a Condition Monitoring (CM) assessment of bobbin coil signal amplitudes for observed possible indications. In addition, a projection of EOC-4a bobbin coil voltage distributions, as well as the associated SG tube leak rates and burst probabilities through EOC-4a conditions, is provided. An itemized list of the TS reporting requirements and location of the information within this report is contained in Section 2. The evaluation is performed for a partial duration of Cycle 4 because the conditional probability of burst would not be satisfied for an entire cycle due to the flaw population observed during U2R3, particularly in SG-3. This will require a mid-cycle inspection to be performed in Cycle 4, which is referred to as U2R4a in this report. The SG inspection to occur during the fourth refueling outage for Watts Bar 2 is referred to as U2R4b in this report.
INTRODUCTION This report provides a summary of the Watts Bar Unit 2 steam generator (SG) bobbin and  
+POINT'1 probe inspections at tube support plate (TSP) intersections from the Fall 2020, U2R3 outage, together with postulated Steam Line Break (SLB) leak rate and tube burst probability analyses.

The SG inspection to occur during the fourth refueling outage for Watts Bar 2 is referred to as U2R4b in this report.
The condition monitoring analysis at EOC-3 was carried out using the actual bobbin coil voltage distributions measured during the U2R3 outage. These results show that the U2R3 condition monitoring leak rates and conditional burst probabilities for all four SGs are within their respective allowable limits with the exception of conditional probability of burst for SG-3. This calculated value exceeds the acceptance criteria value of 1 x 10-2 and a subsequent notification to the Nuclear Regulatory Commission (NRC) was made (Reference 14). These evaluations were performed according to the methodology of WCAP-14277 (Reference 3).

These evaluations were performed according to the methodology of WCAP-14277 (Reference 3).
The Operational Assessment (OA) analysis was performed to project leak rates and tube burst probabilities for postulated SLB conditions at the end of the next inspection interval (EOC-4a). These analyses utilized bobbin voltage distributions measured during the recent (U2R3) inspection and a growth rate distribution bounding the last two inspections (U2R2 and U2R3), with U2R2 bobbin measurements determined from lookbacks to U2R2 data. Leak and burst analyses for the operational assessment were performed using the Reference 4 primary-to-secondary pressure differential of 2405 psi, which credits power-operated relief valve (PORV) actuation.

==SUMMARY==
==SUMMARY==
AND CONCLUSIONS A total of 1240 distorted support indications (DSI and DSV) in all four SGs combined were reported during the Watts Bar Unit 2 (WB2) U2R3 bobbin coil inspection. Per GL 95-05, only those DSI and DSV signals with a bobbin coil signal amplitude of 1.0 volts (lower repair limit) or greater are required to be inspected using a +POINT (or equivalent) probe. However, all indications with bobbin voltage between 0.75V and 1.0V were tested with the +POINT probe to generate data for confirmation rate of bobbin indications. Tubes with indications measured at 1.0V or greater and confirmed by +POINT probe were plugged. Tubes with indications measured at 2.85V or greater (upper repair limit for indications at TSP locations) by bobbin were plugged. Only one indication at a FDB location was found to exceed the upper repair limit for indications at FDB locations of 1.82V, and the tube was also plugged. A total of 199 DSI indications were removed from service by plugging. The maximum bobbin coil voltage indication in all SGs was 9.35 volts on R17 C54 at the flow distribution baffle (FDB) in SG-3.
AND CONCLUSIONS A total of 1240 distorted support indications (DSI and DSV) in all four SGs combined were reported during the Watts Bar Unit 2 (WB2) U2R3 bobbin coil inspection. Per GL 95-05, only those DSI and DSV signals with a bobbin coil signal amplitude of 1.0 volts (lower repair limit) or greater are required to be inspected using a +POINT (or equivalent) probe. However, all indications with bobbin voltage between 0.75V and 1.0V were tested with the +POINT probe to generate data for confirmation rate of bobbin indications. Tubes with indications measured at 1.0V or greater and confirmed by +POINT probe were plugged. Tubes with indications measured at 2.85V or greater (upper repair limit for indications at TSP locations) by bobbin were plugged. Only one indication at a FDB location was found to exceed the upper repair limit for indications at FDB locations of 1.82V, and the tube was also plugged. A total of 199 DSI indications were removed from service by plugging. The maximum bobbin coil voltage indication in all SGs was 9.35 volts on R17 C54 at the flow distribution baffle (FDB) in SG-3.

This conclusion was reported to the NRC during U2R3 (Reference 14).
At U2R3, the largest SLB leak rate in the condition monitoring analysis is calculated for SG-3, with a magnitude of 1.09 gpm, which is below the allowable SLB leakage limit of 3.0 gpm in the faulted SG. All leak rate values quoted are equivalent volumetric rates at room temperature. The limiting conditional tube burst probability from the condition monitoring analysis, 3.005 x 10-2 calculated for SG-3, exceeds the NRC reporting guideline of 1.0 x 10-2. The condition monitoring results for all other SGs are within the allowable limit.

The condition monitoring results for all other SGs are within the allowable limit.
The operational assessment for Cycle 4 was performed for 285 calendar days which was determined to be the maximum operating time for the conditional probability of burst criteria to be satisfied for SG-3. The operational assessment utilized DSI growth which credited lookback to bobbin data from U2R2 for the DSIs detected during U2R3. SLB leak rate and tube burst probability projections at the EOC-4a conditions were performed using the latest alternate repair criteria (ARC) database available for 3/4-inch outside diameter (OD) tubing which is documented in Reference 4. Leak and burst analyses for the Cycle 4 operational assessment were performed using the Reference 4 primary-to-secondary pressure differential of 2405 psi, which credits PORV actuation. SG-3 is predicted to be the limiting SG for leakage and probability of burst. For a projected Cycle 4a duration of 285 calendar days, the EOC-4a leak rate projected for SG-3, when applying the NRC approved alternate POD discussed in Section 6.2, is 0.479 gpm (at room temperature), which is less than the current limit of 3.0 gpm in the faulted SG. This leak rate projection utilized the leak rate calculation methodology of References 5 and 6. The limiting EOC-4a burst probability of 9.812 x 10-3 is calculated for SG-3 and is below the allowable limit of 1.0 x 10-2. Therefore, all acceptance criteria of Reference 1 will be satisfied throughout for 285 calendar days of operation.

In accordance with the guidance provided by GL 95-05, the U2R3 inspection of the Watts Bar Unit 2 SGs consisted of a 100% eddy current (EC) bobbin probe full length examination of the tube bundles in all four SGs.
Tube-to-TSP intersections where the tubes with degradation may potentially collapse or deform as a result of the combined postulated loss-of-coolant accident (LOCA) and safe shutdown earthquake loadings were excluded from the ARC per Reference 7. The EOC-3 eddy current inspection plan included 100% +POINT probe inspection of all hot leg and cold leg dents >2 volts (as measured from the bobbin probe), which exceeds the requirement that the GL 95-05 ARC does not apply to intersections with dents greater than 5 volts. The EOC-3 eddy current inspection plan included 100% +POINT inspection of TSP mix residual signals that could cause a 1.0-volt bobbin signal to be missed or misread, as required by GL 95-05. There were no intersections identified with copper deposits which could interfere with the signal. Therefore, the requirements of the GL 95-05 methodology in Section 1.b of Reference 1 are satisfied.

For the purpose of this report, the three-letter code DSI also includes indications which exceed the upper voltage repair limit and therefore includes those indications which were reported during U2R3 with the three-letter code DSV. DSI indications detected on tubes excluded from application of GL 95-05, as documented in Reference 7, were reported as DSE during the U2R3 inspections. DSE indications are not included in the GL 95-05 assessment and those indications are addressed through standard SG tube integrity assessments.

3.2       Voltage Growth Rates For projection of leak rates and tube burst probabilities at EOC-3, voltage growth rates were developed from the U2R2 and U2R3 inspection bobbin data. Growth is determined when the same indication can be identified in two successive inspections. For the U2R3 preliminary GL 95-05 OA evaluation, there were a total of 155 growth data points used for all four SGs combined. In order to ensure that sufficient and accurate point-to-point growth values were used in the growth projections in this report, the U2R2 historical data was reviewed for all locations where DSIs and DSVs were reported in U2R3, resulting in a point-to-point growth value for each DSI reported at U2R3. Table 3-6, Table 3-7, Table 3-8, Table 3-9, and Table 3-10 show the largest and average DSI voltage growth for each TSP in each SG, and for each TSP in all SGs combined. Table 3-11, Table 3-12, Table 3-13, and Table 3-14, and Table 3-15 show the frequency and cumulative probability distribution of growth as a function of voltage change in each WB2 steam generator during Cycle 3.

To determine if WB2 growth rates exhibited a potential dependency on the beginning of cycle (BOC) voltage, the growth rate data for Cycle 3 was plotted against BOC voltage, and the resulting plot is shown in Figure 3-8. It should be noted that growth data exceeding 5V is not displayed in the figure in order to better display the majority of the data. There were a total of 4 indications with growth exceeding 5V and all had BOC voltages of 0.26V or less. The Cycle 3 growth data, based on bobbin lookups from U2R2, do not show any tendency to increase with the BOC voltage; if at all, the growth seems to decrease with increasing BOC voltage. Therefore, for the purposes of this evaluation, growth can be assumed independent of voltage in the Monte Carlo analysis for the operational assessment.
To determine if WB2 growth rates exhibited a potential dependency on the beginning of cycle (BOC) voltage, the growth rate data for Cycle 3 was plotted against BOC voltage, and the resulting plot is shown in Figure 3-8.

3.3       Probe Wear Criteria The probe wear criterion approved by the NRC (Reference 8) was applied during the U2R3 inspection. When a probe does not pass the 15% wear limit, this alternate criterion requires that only tubes with indications above 75% of the repair limit inspected since the last successful probe wear check be re-inspected with a good probe. As the lower repair limit for Watts Bar Unit 2 is 1.00 volts, all tubes containing indications for which the worn probe voltage is above 0.75 volts are to be inspected with a new probe.

4.2       Burst Correlation The burst pressure, Pb, is normalized to a material with a flow stress of 71.565 ksi, which is the mean of the Westinghouse 3/4-inch tube data. This aligns with the flow stress values used in the burst pressure analysis. The correlation parameters used in the analysis are taken from Table 6-1 in Reference 4.

Therefore, the SLB primary-to-secondary pressure differential was selected as 2405 psi for the leak correlation per Reference 13 which is used for the leakage predictions in this analysis. The parameters used in the analysis are taken from Table 6-3 in Reference 4. The leak rate criterion is given in terms of gallons per minute as condensed liquid at room temperature.

4.4       Probability of Leak Correlation The probability of leak as a function of indication voltage parameters are taken from Table 6-2 of Reference 4. 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-3 and EOC-4a voltage projections are described in Reference 1. The probe wear uncertainty has a standard deviation of 7% about a mean of zero and has a cut-off at 15% based on implementation of the probe wear standard. The analyst 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 burst probabilities and accident leak rates at EOC-3 and EOC-4a.

WESTINGHOUSE NON-PROPRIETARY CLASS 3                                                   5-1 5         SLB ANALYSIS METHODS A Monte Carlo analysis technique is used to calculate the SLB leak rates and tube burst probabilities for both actual U2R3 and projected EOC-4a voltage 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 Carlo computer program used to implement this method is documented in Reference 9.
WESTINGHOUSE NON-PROPRIETARY CLASS 3 5-1 SG-CDMP-21-1-NP February 2021 Revision 0 5
In general, the methodology involves application of correlations for burst pressure, probability of leakage and leak rate to a measured or calculated EOC voltage distribution to estimate the likelihood of tube burst and primary-to-secondary leakage during a postulated SLB event. Uncertainties associated with burst pressure, leak rate probability and leak rate correlation parameters are explicitly included by sampling distributions for the parameter uncertainties through the Monte Carlo sampling process. NDE uncertainties are also included. The voltage distributions used in the leak and burst projections for the next operating cycle are obtained by applying growth data to the BOC distribution.

6.1       Calculation of Voltage Distributions An initial voltage distribution for BOC-4a is determined based on the EOC-3 voltage distribution and the POD. The BOC-4a voltage distribution is projected to the end-of-cycle conditions based on the growth rate and the anticipated cycle operating duration. The POD applied was specifically developed for Watts Bar Unit 2 for use in GL 95-05 calculations for Cycle 4 and is discussed in greater detail in Section 6.2. The calculation of projected bobbin voltage frequency distribution is based on a net total number of indications returned to service, defined as follows.

There are no deplugged tubes returned to service at the beginning of Cycle 4a (BOC-4a); therefore, Ndeplugged = 0. Several tubes were plugged due to DSI exceeding the upper repair limit, RPC confirmed above the lower repair limit, or for other degradation mechanisms. During the Monte Carlo simulations, voltages for bins with several indications are selected by randomly sampling the voltage bins.

The POD is a step function where the default value of 0.6 is used up to an indication size of 3.2V at which point the POD increases to 0.9. A POD of 0.9 is maintained up to an indication size of 6.0V, at which point the POD increases to 0.95. The POD is developed based on the inspection technique implemented at U2R3 as well as WB2 plant-specific noise. The POD is applied to all four SGs for determination of BOC-4a flaw distributions. NRC approval of the alternate POD is documented in Reference 12.

6.3       Limiting Growth Rate Distribution As discussed in Section 3.2, the NRC guidelines in Generic Letter 95-05 stipulate that the more conservative growth rate distributions from the past two inspections should be utilized for projecting EOC distributions for the next cycle. Since EOC-3 is the first application of GL 95-05 at Watts Bar Unit 2 and relatively few DSI indications were recorded during EOC-2 inspections, the Cycle 3 growth is limiting. The Cycle 3 growth distributions were determined utilizing bobbin lookbacks of U2R2 eddy current testing (ECT) data to develop meaningful growth distributions which contain at least 200 growth points. Growth distributions were determined for each individual SG and can be seen in Figure 6-3. Performing the lookbacks and creating distributions for each SG provides a more comprehensive and accurate look at the voltage growth that has occurred over the past cycle. For conservatism, the bounding growth curve (SG-3) was used as input for the operational assessment performed individually for each SG. Growth distributions used in the Monte Carlo calculations are specified in the form of a histogram, so no interpolation is performed between growth bins. This assures that the largest growth value in the distribution is utilized in the Monte Carlo simulations.

power and it is unknown at the time of this report whether that power level will be maintained or adjusted prior to the planned mid-cycle outage. The use of EFPD in tube integrity calculations is intended to account for startups, cooldowns and downpowers; it is not intended for use in extension of the cycle length due to operating at a lower power. Therefore, although the reported value is EFPD, in this circumstance that value should be considered to be calendar days of operation without adjustment for operating power levels.

The BOC-4a distributions were adjusted to account for probability of detection as described above, and the adjusted number of indications at BOC-4a is also shown in Table 6-1. Calculations were performed using the alternate POD described in Section 6.2 and 1,000,000 Monte Carlo trials. The distribution of indications at BOC-4a and the distribution of indications projected at EOC-4a are shown in Figure 6-1, Figure 6-2, Figure 6-3, and Figure 6-4 for SG-1, SG-2, SG-3 and SG-4, respectively. SG-3 has the largest number of indications at BOC-4a. For clarity, fractional EOC voltage predictions below 1.0 are not shown in Figure 6-1, Figure 6-2, Figure 6-3, and Figure 6-4. Therefore, higher voltage bins are not displayed in these figures. The maximum voltage where a fractional number of indications are projected at EOC-4a is displayed in Table 7-2 for each SG.

7.1       U2R3 Condition Monitoring Leak Rate and Tube Burst Probability Analyses to calculate the U2R3 SLB leak rates and tube burst probabilities were performed using the actual bobbin voltage distributions presented in Table 3-2,Table 3-3,Table 3-4, and Table 3-5. The results of the Monte Carlo calculations are summarized in Table 7-1. As a result, the OA produces conservative results for leak rate and burst probability by the end of the next operating cycle.

The SLB leak rates and tube burst probabilities, calculated using the actual measured U2R3 voltage distributions using 1,000,000 Monte Carlo trials, are shown in Table 7-1. The methodology used for these calculations is documented in WCAP-14277, Revision 1 (Reference 3). The probability of leak, leak rate, and burst pressure correlations for 3/4-inch tubes presented in the latest addendum to the Electric Power Research Institute (EPRI) Alternate Repair Criteria (ARC)

Database, Reference 4, were used. The SLB primary-to-secondary pressure differential applied in the analysis is 2405 psi (Reference 13). While the leak rate and conditional burst probability acceptance criteria are met for SGs 1, 2 and 4, SG-3 did not meet condition monitoring criteria with a conditional burst probability of 3.005 x 10-2. This conclusion was reported to the NRC during U2R3 (Reference 14).

While the leak rate and conditional burst probability acceptance criteria are met for SGs 1, 2 and 4, SG-3 did not meet condition monitoring criteria with a conditional burst probability of 3.005 x 10-2. This conclusion was reported to the NRC during U2R3 (Reference 14).
7.2       EOC-4a Operational Assessment Leak Rate and Tube Burst Probability The SLB leak rate and tube burst probability projections for the Cycle 4 Operational Assessment were performed using the latest update to the ARC database documented in Reference 4, the NRC approved alternate POD described in Section 6.2, and 1,000,000 Monte Carlo trials. The EOC-4a leak and burst analyses were performed using a primary-to-secondary pressure differential of 2405 psi, which credits PORV actuation prior to the pressurizer safety relief valve lift setting (Reference 13).

The EOC-4a leak and burst analyses were performed using a primary-to-secondary pressure differential of 2405 psi, which credits PORV actuation prior to the pressurizer safety relief valve lift setting (Reference 13).
The EOC-4a projections considering a 285 calendar day operation cycle and using the alternate POD discussed in Section 6.2 are displayed in Table 7-2. Both the maximum projected EOC-4a leak rate of 0.47 gpm and the maximum conditional burst probability of 9.610 x 10-3 are below the allowable limits (3.0 gpm and 1.0 x 10-2, respectively). Therefore, the operational assessment performance criteria for the U2R3 flaw distribution are satisfied for 285 calendar days of operation into Cycle 4.

INTRODUCTION This report provides a summary of the Watts Bar Unit 2 steam generator (SG) bobbin and

+POINT'1 probe inspections at tube support plate (TSP) intersections from the Fall 2020, U2R3 outage, together with postulated Steam Line Break (SLB) leak rate and tube burst probability analyses. The U2R3 outage represents the first application of the Generic Letter (GL) 95-05 (Reference 1) voltage-based repair criteria, and implementation of its requirements, to the Watts Bar Unit 2 SGs. Information required by the GL 95-05 and by WBN Technical Specification 5.9.9 is provided in this report, including steam line break (SLB) leak rates and tube burst probabilities calculated using the end-of-cycle (EOC) conditions for the recently completed Cycle 3, representing a Condition Monitoring (CM) assessment of bobbin coil signal amplitudes for observed possible indications. In addition, a projection of EOC-4a bobbin coil voltage distributions, as well as the associated SG tube leak rates and burst probabilities through EOC-4a conditions, is provided. An itemized list of the TS reporting requirements and location of the information within this report is contained in Section 2. The evaluation is performed for a partial duration of Cycle 4 because the conditional probability of burst would not be satisfied for an entire cycle due to the flaw population observed during U2R3, particularly in SG-3. This will require a mid-cycle inspection to be performed in Cycle 4, which is referred to as U2R4a in this report. The SG inspection to occur during the fourth refueling outage for Watts Bar 2 is referred to as U2R4b in this report.

The condition monitoring analysis at EOC-3 was carried out using the actual bobbin coil voltage distributions measured during the U2R3 outage. These results show that the U2R3 condition monitoring leak rates and conditional burst probabilities for all four SGs are within their respective allowable limits with the exception of conditional probability of burst for SG-3. This calculated value exceeds the acceptance criteria value of 1 x 10-2 and a subsequent notification to the Nuclear Regulatory Commission (NRC) was made (Reference 14). These evaluations were performed according to the methodology of WCAP-14277 (Reference 3).

The Operational Assessment (OA) analysis was performed to project leak rates and tube burst probabilities for postulated SLB conditions at the end of the next inspection interval (EOC-4a). These analyses utilized bobbin voltage distributions measured during the recent (U2R3) inspection and a growth rate distribution bounding the last two inspections (U2R2 and U2R3), with U2R2 bobbin measurements determined from lookbacks to U2R2 data. Leak and burst analyses for the operational assessment were performed using the Reference 4 primary-to-secondary pressure differential of 2405 psi, which credits power-operated relief valve (PORV) actuation.

SUMMARY

AND CONCLUSIONS A total of 1240 distorted support indications (DSI and DSV) in all four SGs combined were reported during the Watts Bar Unit 2 (WB2) U2R3 bobbin coil inspection. Per GL 95-05, only those DSI and DSV signals with a bobbin coil signal amplitude of 1.0 volts (lower repair limit) or greater are required to be inspected using a +POINT (or equivalent) probe. However, all indications with bobbin voltage between 0.75V and 1.0V were tested with the +POINT probe to generate data for confirmation rate of bobbin indications. Tubes with indications measured at 1.0V or greater and confirmed by +POINT probe were plugged. Tubes with indications measured at 2.85V or greater (upper repair limit for indications at TSP locations) by bobbin were plugged. Only one indication at a FDB location was found to exceed the upper repair limit for indications at FDB locations of 1.82V, and the tube was also plugged. A total of 199 DSI indications were removed from service by plugging. The maximum bobbin coil voltage indication in all SGs was 9.35 volts on R17 C54 at the flow distribution baffle (FDB) in SG-3.

WBN Technical Specification 5.9.9 specifies that the GL 95-05 90-day report shall include information described in Section 6.b of Attachment 1 to GL 95-05. This information is contained within this report in the location noted next to each item in the table below. No tubes were pulled during U2R3 for metallurgical examination associated with GL 95-05 Item 6.b(a).

WESTINGHOUSE NON-PROPRIETARY CLASS 3 2-3 SG-CDMP-21-1-NP February 2021 Revision 0 voltage distributions (operational assessment). The SLB leak rates from the condition monitoring analysis meet the faulted SG allowable limit of 3.0 gpm (room temperature), Reference 11. The corresponding condition monitoring tube burst probability values are below the allowable limit of 1.0 x 10-2, with the exception of SG-3 which exceeds the conditional probability of burst limit.

This conclusion was reported to the NRC during U2R3 (Reference 14).

At U2R3, the largest SLB leak rate in the condition monitoring analysis is calculated for SG-3, with a magnitude of 1.09 gpm, which is below the allowable SLB leakage limit of 3.0 gpm in the faulted SG. All leak rate values quoted are equivalent volumetric rates at room temperature. The limiting conditional tube burst probability from the condition monitoring analysis, 3.005 x 10-2 calculated for SG-3, exceeds the NRC reporting guideline of 1.0 x 10-2. The condition monitoring results for all other SGs are within the allowable limit.

The operational assessment for Cycle 4 was performed for 285 calendar days which was determined to be the maximum operating time for the conditional probability of burst criteria to be satisfied for SG-3. The operational assessment utilized DSI growth which credited lookback to bobbin data from U2R2 for the DSIs detected during U2R3. SLB leak rate and tube burst probability projections at the EOC-4a conditions were performed using the latest alternate repair criteria (ARC) database available for 3/4-inch outside diameter (OD) tubing which is documented in Reference 4. Leak and burst analyses for the Cycle 4 operational assessment were performed using the Reference 4 primary-to-secondary pressure differential of 2405 psi, which credits PORV actuation. SG-3 is predicted to be the limiting SG for leakage and probability of burst. For a projected Cycle 4a duration of 285 calendar days, the EOC-4a leak rate projected for SG-3, when applying the NRC approved alternate POD discussed in Section 6.2, is 0.479 gpm (at room temperature), which is less than the current limit of 3.0 gpm in the faulted SG. This leak rate projection utilized the leak rate calculation methodology of References 5 and 6. The limiting EOC-4a burst probability of 9.812 x 10-3 is calculated for SG-3 and is below the allowable limit of 1.0 x 10-2. Therefore, all acceptance criteria of Reference 1 will be satisfied throughout for 285 calendar days of operation.

U2R3 INSPECTION RESULTS AND VOLTAGE GROWTH RATES 3.1 U2R3 Inspection Results U2R3 is the first refueling outage for which the alternate repair criterion per GL 95-05 have been approved and implemented for Watts Bar Unit 2. In accordance with the guidance provided by GL 95-05, the U2R3 inspection of the Watts Bar Unit 2 SGs consisted of a 100% eddy current (EC) bobbin probe full length examination of the tube bundles in all four SGs.

Tube-to-TSP intersections where the tubes with degradation may potentially collapse or deform as a result of the combined postulated loss-of-coolant accident (LOCA) and safe shutdown earthquake loadings were excluded from the ARC per Reference 7. The EOC-3 eddy current inspection plan included 100% +POINT probe inspection of all hot leg and cold leg dents >2 volts (as measured from the bobbin probe), which exceeds the requirement that the GL 95-05 ARC does not apply to intersections with dents greater than 5 volts. The EOC-3 eddy current inspection plan included 100% +POINT inspection of TSP mix residual signals that could cause a 1.0-volt bobbin signal to be missed or misread, as required by GL 95-05. There were no intersections identified with copper deposits which could interfere with the signal. Therefore, the requirements of the GL 95-05 methodology in Section 1.b of Reference 1 are satisfied.

All DSI indications which matched or exceeded the lower repair limit of 1.0 volt were subject to

+POINT inspection in accordance with GL 95-05 (Reference 1). All DSI indications which exceeded the upper voltage repair limit of 2.85 volts at tube-TSP intersections and 1.82 volts at FDB intersections were plugged. The upper voltage repair criteria applied to the tube-to-TSP intersections and tube-to-FDB intersections are in accordance with Sections 2.a.2 and 2.a.3 of Reference 1, respectively.

The three-letter code for DSI indications which exceeded the upper voltage repair limit was reported as DSV instead of DSI. For the purpose of this report, the three-letter code DSI also includes indications which exceed the upper voltage repair limit and therefore includes those indications which were reported during U2R3 with the three-letter code DSV. DSI indications detected on tubes excluded from application of GL 95-05, as documented in Reference 7, were reported as DSE during the U2R3 inspections. DSE indications are not included in the GL 95-05 assessment and those indications are addressed through standard SG tube integrity assessments.

Table 3-1 provides a summary of the number of DSI indications reported in U2R3 which were less than the lower voltage repair limit, greater than the lower voltage repair limit but less than the upper voltage repair limit, and greater than the upper voltage repair limit for each SG.

12 Total DSIs 200 314 400 326 1240 Table 3-2, Table 3-3, Table 3-4, and Table 3-5 present the U2R3 bobbin DSI voltage data for the TSP intersections in the four SGs. A total of 1240 DSI indications at TSP locations were detected in all four SGs combined, of which 176 indications had voltage amplitudes greater than 1.0 volt and less than the upper voltage repair limit. A total of 12 indications exceeded the upper voltage repair limit. For the analyses, the DSI indications are binned in 0.1-volt intervals where the numeric value of the bin represents the upper range of the bin. For example, the 1.0-volt bin contains DSI voltages from 0.91 to 1.00 volt. For U2R3, all DSIs with a voltage amplitude greater than or equal to 0.75 volts were tested using the +POINT probe which exceeds the GL 95-05 requirement to RPC test indications that exceed the lower repair limit by bobbin coil.

There a total of 289 new DSI indications confirmed by +POINT probe in U2R3. The indications were confirmed as Single Axial Indication (SAI) or Multiple Axial Indications (MAI) after analyst review of the RPC data.

  • 21 SAIs and 3 MAIs in SG-1
  • 41 SAIs and 8 MAIs in SG-2
  • 75 SAIs and 80 MAIs in SG-3
  • 60 SAIs and 1 MAI in SG-4 Table 3-2, Table 3-3, Table 3-4 and Table 3-5 tabulate the number of field bobbin indications, the number of those indications that were +POINT probe rotating pancake coil (RPC) inspected, the number of +POINT probe RPC confirmed indications, the number of indications removed from service, and the number of indications returned to service. The distribution of U2R3 indications is also shown in Figure 3-1, Figure 3-2, Figure 3-3, and Figure 3-4 for SG-1, SG-2, SG-3, and SG-4, respectively.

The distribution of U2R3 indications as a function of support plate location is summarized in Table 3-6, Table 3-7, Table 3-8, Table 3-9 and Table 3-10 and shown in Figure 3-5. This includes the average Cycle 3 growth for each support plate location (calculated with negative growth set to

0) and the total average growth for each generator (calculated with negative growth values). The data indicates that the lower hot leg TSPs have the most ODSCC indications, reducing with TSP elevation after either the first or second TSP. The highest TSP elevation with an RPC confirmed DSI was H06 in SG4 at one location. There were virtually no DSIs reported at the FDB with the exception of 3 reported indications in SG-3. Only 18 indications were detected on the cold leg side; only one of these exceeded 1.0 volt and this location was NDF by +POINT exam. This distribution is consistent with that observed at other plants and is commonly attributed to the temperature dependence of outside diameter stress corrosion cracking (ODSCC).

WESTINGHOUSE NON-PROPRIETARY CLASS 3 3-3 SG-CDMP-21-1-NP February 2021 Revision 0 Appendix A provides a listing of all DSIs and voltages reported at the WBN U2R3 outage in Table A-1, Table A-2, Table A-3, and Table A-4, and includes whether axial ODSCC was confirmed as an SAI or MAI, whether the tube containing the indication(s) was plugged, and whether the indication was tested and no defect was found.

3.2 Voltage Growth Rates For projection of leak rates and tube burst probabilities at EOC-3, voltage growth rates were developed from the U2R2 and U2R3 inspection bobbin data. Growth is determined when the same indication can be identified in two successive inspections. For the U2R3 preliminary GL 95-05 OA evaluation, there were a total of 155 growth data points used for all four SGs combined. In order to ensure that sufficient and accurate point-to-point growth values were used in the growth projections in this report, the U2R2 historical data was reviewed for all locations where DSIs and DSVs were reported in U2R3, resulting in a point-to-point growth value for each DSI reported at U2R3. Table 3-6, Table 3-7, Table 3-8, Table 3-9, and Table 3-10 show the largest and average DSI voltage growth for each TSP in each SG, and for each TSP in all SGs combined. Table 3-11, Table 3-12, Table 3-13, and Table 3-14, and Table 3-15 show the frequency and cumulative probability distribution of growth as a function of voltage change in each WB2 steam generator during Cycle 3.

Table 3-16 lists the top 23 indications based on the Cycle 3 growth rate in descending order.

The Cycle 3 voltage growth distributions for each SG are shown in Figure 3-5 and Figure 3-6.

From the figure, it is understood that SG-3 growth was the highest of the four generators. Figure 3-7 provides a magnified view of the upper 5% tail of the growth curves for all four SGs.

To determine if WB2 growth rates exhibited a potential dependency on the beginning of cycle (BOC) voltage, the growth rate data for Cycle 3 was plotted against BOC voltage, and the resulting plot is shown in Figure 3-8. It should be noted that growth data exceeding 5V is not displayed in the figure in order to better display the majority of the data. There were a total of 4 indications with growth exceeding 5V and all had BOC voltages of 0.26V or less. The Cycle 3 growth data, based on bobbin lookups from U2R2, do not show any tendency to increase with the BOC voltage; if at all, the growth seems to decrease with increasing BOC voltage. Therefore, for the purposes of this evaluation, growth can be assumed independent of voltage in the Monte Carlo analysis for the operational assessment.

3.3 Probe Wear Criteria The probe wear criterion approved by the NRC (Reference 8) was applied during the U2R3 inspection. When a probe does not pass the 15% wear limit, this alternate criterion requires that only tubes with indications above 75% of the repair limit inspected since the last successful probe wear check be re-inspected with a good probe. As the lower repair limit for Watts Bar Unit 2 is 1.00 volts, all tubes containing indications for which the worn probe voltage is above 0.75 volts are to be inspected with a new probe.

3.4 NDE Uncertainties The NDE uncertainties applied for the Cycle 3 voltage distributions in the Monte Carlo analyses for leak rate and burst probabilities are the same as those in the NRC Generic Letter 95-05 (Reference 1).

The probe wear uncertainty has a standard deviation of 7.0% about a mean of zero and has a cut-off at 15% based on implementation of the probe wear standard. If the random sample of probe wear

WESTINGHOUSE NON-PROPRIETARY CLASS 3 3-4 SG-CDMP-21-1-NP February 2021 Revision 0 selected during the Monte Carlo simulations exceeds 15%, sampling of the probe wear distribution is continued until a value less than 15% is picked. The analyst variability uncertainty has a standard deviation of 10.3% about a mean of zero with no cut-off. These nondestructive examination (NDE) uncertainty distributions are included in the Monte Carlo analyses for SLB leak rates and tube burst probabilities based on the U2R3 actual voltage distributions as well as for the EOC-4a projections.

DATABASE APPLIED FOR LEAK AND BURST CORRELATIONS 4.1 Tube Material Properties The tube material properties are provided in Table 4-1 of Reference 2 for the 3/4-inch diameter tubes in the WB2 SGs at 650°F. The normalized mean flow stress (sum of yield and ultimate strengths divided by 2) used in the analysis is 71.565 ksi with a standard deviation of 3.565 ksi.

4.2 Burst Correlation The burst pressure, Pb, is normalized to a material with a flow stress of 71.565 ksi, which is the mean of the Westinghouse 3/4-inch tube data. This aligns with the flow stress values used in the burst pressure analysis. The correlation parameters used in the analysis are taken from Table 6-1 in Reference 4.

4.3 Leak Rate Correlation The steam line break pressure to be applied is typically 2560 psi unless a lower pressure can be justified. At WB2, credit can be taken for operability of the pressurizer PORVs during a SLB event.

Therefore, the SLB primary-to-secondary pressure differential was selected as 2405 psi for the leak correlation per Reference 13 which is used for the leakage predictions in this analysis. The parameters used in the analysis are taken from Table 6-3 in Reference 4. The leak rate criterion is given in terms of gallons per minute as condensed liquid at room temperature.

4.4 Probability of Leak Correlation The probability of leak as a function of indication voltage parameters are taken from Table 6-2 of Reference 4. 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-3 and EOC-4a voltage projections are described in Reference 1. The probe wear uncertainty has a standard deviation of 7% about a mean of zero and has a cut-off at 15% based on implementation of the probe wear standard. The analyst 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 burst probabilities and accident leak rates at EOC-3 and EOC-4a.

SLB ANALYSIS METHODS A Monte Carlo analysis technique is used to calculate the SLB leak rates and tube burst probabilities for both actual U2R3 and projected EOC-4a voltage 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 Carlo computer program used to implement this method is documented in Reference 9.

In general, the methodology involves application of correlations for burst pressure, probability of leakage and leak rate to a measured or calculated EOC voltage distribution to estimate the likelihood of tube burst and primary-to-secondary leakage during a postulated SLB event. Uncertainties associated with burst pressure, leak rate probability and leak rate correlation parameters are explicitly included by sampling distributions for the parameter uncertainties through the Monte Carlo sampling process. NDE uncertainties are also included. The voltage distributions used in the leak and burst projections for the next operating cycle are obtained by applying growth data to the BOC distribution.

BOBBIN VOLTAGE DISTRIBUTIONS This section describes the input data used to calculate EOC bobbin voltage distributions and presents results of calculations to project EOC-4a voltage distributions. The cycle length used to project the EOC condition at the planned mid-cycle outage (EOC-4a) for the operational assessment is 285 days.

6.1 Calculation of Voltage Distributions An initial voltage distribution for BOC-4a is determined based on the EOC-3 voltage distribution and the POD. The BOC-4a voltage distribution is projected to the end-of-cycle conditions based on the growth rate and the anticipated cycle operating duration. The POD applied was specifically developed for Watts Bar Unit 2 for use in GL 95-05 calculations for Cycle 4 and is discussed in greater detail in Section 6.2. The calculation of projected bobbin voltage frequency distribution is based on a net total number of indications returned to service, defined as follows.

NTot RTS = Ni / POD - Nrepaired + Ndeplugged

where, NTot RTS

= Number of bobbin indications being returned to service for the next cycle, Ni

=

Number of bobbin indications (in tubes in service) identified by inspection after the previous cycle, POD =

Probability of detection, Nrepaired

= Number of Ni which are repaired (plugged) after the last cycle, Ndeplugged

= Number of indications in tubes deplugged after the last cycle and returned to service in accordance with voltage-based repair criteria.

There are no deplugged tubes returned to service at the beginning of Cycle 4a (BOC-4a); therefore, Ndeplugged = 0. Several tubes were plugged due to DSI exceeding the upper repair limit, RPC confirmed above the lower repair limit, or for other degradation mechanisms. During the Monte Carlo simulations, voltages for bins with several indications are selected by randomly sampling the voltage bins.

The methodology used in the projection of EOC-4a bobbin voltage frequency distributions is described in Reference 3.

6.2 Probability of Detection (POD)

The Generic Letter 95-05 (Reference 1) requires the application of a constant POD value of 0.6 to define the BOC distribution for EOC voltage 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.

Reference 10 provides the technical basis for the use of an alternate POD at Watts Bar Unit 2 for

      • This record was final approved on 2/10/2021 3:23:04 PM. (This statement was added by the PRIME system upon its validation)

WESTINGHOUSE NON-PROPRIETARY CLASS 3 6-2 SG-CDMP-21-1-NP February 2021 Revision 0 Cycle 4a GL 95-05 ARC calculations. The POD is a step function where the default value of 0.6 is used up to an indication size of 3.2V at which point the POD increases to 0.9. A POD of 0.9 is maintained up to an indication size of 6.0V, at which point the POD increases to 0.95. The POD is developed based on the inspection technique implemented at U2R3 as well as WB2 plant-specific noise. The POD is applied to all four SGs for determination of BOC-4a flaw distributions. NRC approval of the alternate POD is documented in Reference 12.

6.3 Limiting Growth Rate Distribution As discussed in Section 3.2, the NRC guidelines in Generic Letter 95-05 stipulate that the more conservative growth rate distributions from the past two inspections should be utilized for projecting EOC distributions for the next cycle. Since EOC-3 is the first application of GL 95-05 at Watts Bar Unit 2 and relatively few DSI indications were recorded during EOC-2 inspections, the Cycle 3 growth is limiting. The Cycle 3 growth distributions were determined utilizing bobbin lookbacks of U2R2 eddy current testing (ECT) data to develop meaningful growth distributions which contain at least 200 growth points. Growth distributions were determined for each individual SG and can be seen in Figure 6-3. Performing the lookbacks and creating distributions for each SG provides a more comprehensive and accurate look at the voltage growth that has occurred over the past cycle. For conservatism, the bounding growth curve (SG-3) was used as input for the operational assessment performed individually for each SG. Growth distributions used in the Monte Carlo calculations are specified in the form of a histogram, so no interpolation is performed between growth bins. This assures that the largest growth value in the distribution is utilized in the Monte Carlo simulations.

6.4 Cycle Operating Period The operating periods used in the growth rate/EFPY calculations and voltage projections are as follows.

Cycle 3 496.3 EFPD (actual)

Partial Cycle 4 (Cycle 4a) -285 EFPD* (assumed)

  • The cycle length of 285 days which is selected for the OA is calculated to be the maximum amount of days SG-3 could operate into Cycle 4 and meet the acceptance criteria for POB. The OA duration is measured in calendar days since WB2 is currently operating at less than 100%

power and it is unknown at the time of this report whether that power level will be maintained or adjusted prior to the planned mid-cycle outage. The use of EFPD in tube integrity calculations is intended to account for startups, cooldowns and downpowers; it is not intended for use in extension of the cycle length due to operating at a lower power. Therefore, although the reported value is EFPD, in this circumstance that value should be considered to be calendar days of operation without adjustment for operating power levels.

WESTINGHOUSE NON-PROPRIETARY CLASS 3 6-3 SG-CDMP-21-1-NP February 2021 Revision 0 6.5 Projected EOC-4a Voltage Distribution Calculations for the EOC-4a bobbin voltage projections were performed for all four SGs based on the U2R3 distributions shown in Table 6-1. The BOC-4a distributions were adjusted to account for probability of detection as described above, and the adjusted number of indications at BOC-4a is also shown in Table 6-1. Calculations were performed using the alternate POD described in Section 6.2 and 1,000,000 Monte Carlo trials. The distribution of indications at BOC-4a and the distribution of indications projected at EOC-4a are shown in Figure 6-1, Figure 6-2, Figure 6-3, and Figure 6-4 for SG-1, SG-2, SG-3 and SG-4, respectively. SG-3 has the largest number of indications at BOC-4a. For clarity, fractional EOC voltage predictions below 1.0 are not shown in Figure 6-1, Figure 6-2, Figure 6-3, and Figure 6-4. Therefore, higher voltage bins are not displayed in these figures. The maximum voltage where a fractional number of indications are projected at EOC-4a is displayed in Table 7-2 for each SG. Fractional values are considered in the determination of probability of burst and leak rates for the OA calculation.

SLB LEAK RATE AND TUBE BURST 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 distributions from the U2R3 inspection (condition monitoring assessment) as well as for the projected EOC-4a voltage distributions (operational assessment). The methodology used in these analyses is described in Section 6.

7.1 U2R3 Condition Monitoring Leak Rate and Tube Burst Probability Analyses to calculate the U2R3 SLB leak rates and tube burst probabilities were performed using the actual bobbin voltage distributions presented in Table 3-2,Table 3-3,Table 3-4, and Table 3-5. The results of the Monte Carlo calculations are summarized in Table 7-1. As a result, the OA produces conservative results for leak rate and burst probability by the end of the next operating cycle.

The SLB leak rates and tube burst probabilities, calculated using the actual measured U2R3 voltage distributions using 1,000,000 Monte Carlo trials, are shown in Table 7-1. The methodology used for these calculations is documented in WCAP-14277, Revision 1 (Reference 3). The probability of leak, leak rate, and burst pressure correlations for 3/4-inch tubes presented in the latest addendum to the Electric Power Research Institute (EPRI) Alternate Repair Criteria (ARC)

Database, Reference 4, were used. The SLB primary-to-secondary pressure differential applied in the analysis is 2405 psi (Reference 13). While the leak rate and conditional burst probability acceptance criteria are met for SGs 1, 2 and 4, SG-3 did not meet condition monitoring criteria with a conditional burst probability of 3.005 x 10-2. This conclusion was reported to the NRC during U2R3 (Reference 14).

7.2 EOC-4a Operational Assessment Leak Rate and Tube Burst Probability The SLB leak rate and tube burst probability projections for the Cycle 4 Operational Assessment were performed using the latest update to the ARC database documented in Reference 4, the NRC approved alternate POD described in Section 6.2, and 1,000,000 Monte Carlo trials. The EOC-4a leak and burst analyses were performed using a primary-to-secondary pressure differential of 2405 psi, which credits PORV actuation prior to the pressurizer safety relief valve lift setting (Reference 13).

The EOC-4a projections considering a 285 calendar day operation cycle and using the alternate POD discussed in Section 6.2 are displayed in Table 7-2. Both the maximum projected EOC-4a leak rate of 0.47 gpm and the maximum conditional burst probability of 9.610 x 10-3 are below the allowable limits (3.0 gpm and 1.0 x 10-2, respectively). Therefore, the operational assessment performance criteria for the U2R3 flaw distribution are satisfied for 285 calendar days of operation into Cycle 4.
