V GLOSSARY OF ACRONYMS BOC - Beginning of operation cycle. The current inspection is just prior to BOC-15.

EOC - End of operation cycle. The current inspection is at EOC-14. The end of the next cycle is EOC-15.

NODP - Normal operating differential pressure.

MRPC - Motorized rotating pancake coil. Also refers to the Plus-Point coil.

ODSCC - Outside diameter stress corrosion cracking.

POD - Probability of detection. This value is set equal to 0.60 for the GL-95-05 predictive analysis for the condition of the steam generators at the end of the next cycle.

SG - Steam generator identifier. Specifically SG 1, SG 2, SG 3 and SG 4.

TSP - Tube support plate. The generic letter 95-05 alternate repair criterion applies to ODSCC in the tubes at the TSPs.

1.0 INTRODUCTION

Sequoyah Unit 2 completed its Cycle 14 of operation and subsequent steam generator tube inspection in December 2006. Axial ODSCC has been confirmed within the TSP regions of the steam generators and is a current degradation mechanism at Sequoyah Unit 2. The alternate repair criterion (ARC) defined in NRC Generic Letter 95-05 (Reference 1) is implemented at Sequoyah Unit 2. This report provides a condition monitoring assessment that demonstrates that the GL-95-05 acceptance criteria were satisfied at the end of operational Cycle 14 (EOC-14), and an operational assessment that demonstrates that the GL 95-05 acceptance criteria will continue to be satisfied throughout operational Cycle 15. A Sequoyah-2 specific voltage growth rate was used in the EOC-15 prediction.

The operation cycle just completed, Cycle 14, was 537.1 Effective Full Power Days (EFPD). The next cycle, Cycle 15 is estimated to be 481 EFPD (Reference 2).

SUMMARY

AND CONCLUSIONS Bobbin voltage indications of ODSCC at the tube support plates were detected and measured in all four steam generators. Based on this voltage distribution, using the methodology of Reference 1 and Reference 3, a Condition Monitoring evaluation including the computation of the probability of tube burst (POB) and the amount of leakage predicted for steam line break conditions at EOC-14 was performed. The acceptance criteria on POB and leakage are satisfied with significant margin.

The change in voltage from the previous inspection was determined by historical review for each indication detected. The apparent voltage growth rate during Cycle 14 was based on the historic review of 2747 DSI indications identified during the Sequoyah Unit 2 EOC-14 inspection. An operational assessment prediction of the POB and leakage at steam line break conditions at EOC-15 was performed using a site specific bounding growth rate. The results indicate that the acceptance criteria on POB and leakage at EOC- 15 will be satisfied with acceptable margin.

Therefore the Reference 1 acceptance criteria will be satisfied throughout Cycle 15.

Summary and Conclusions March 2007 SG-CDME-07-7 Revision 1 9

3-1 3.0 EOC-14 INSPECTION RESULTS 3.1 VOLTAGE DISTRIBUTIONS AT EOC-14 Summaries of eddy current signal voltage distributions at the drilled support plates, for each steam generator, are shown in Table 3-1 through Table 3-4. Also shown are the number of indications in each voltage range detected at EOC- 14 and the number of indications removed from service due to tube repairs for any reason. The number of indications that remain in service for Cycle 15 is the difference between the number of indications detected and the number of indications removed from service. No tubes were unplugged with the intent to return them to service after inspection.

Appendix A contains a listing of all DSI indications and their repair status. All DSI indications with an EOC-14 voltage greater to or equal to 2 volts were subject to Plus Point inspections, in accordance with Reference 1 requirements for 7/8-inch diameter tubing. Plugging repaired indications confirmed as being present by the Plus Point inspection.

The summary of all four-steam generators shows the following:

" A total of 2747 TSP regions were identified as having ODSCC bobbin signal indications (DSIs) during the inspection. This includes four TSP regions identified as having ODSCC by MRPC (but without a bobbin DSI) whose DSI voltage was imputed by statistical means.

• As noted in Reference 4, Sequoyah-2 does not have intersections that are excluded from the voltage-based repair criteria (Section 1.b. 1 of Reference 1). None of these 2747 indications were associated with a dent signal greater than 5 volts, copper deposits, or mixed residuals of sufficient magnitude to cause a 1.0 volt ODSCC indication to be missed or misread

• Of the 2747 TSP regions, 11 had DSI indications above 2 volts.

" All indication with voltages greater than or equal to 2 volts, were subjected to an inspection with a Plus Point probe. Indications that confirmed during the Plus Point inspection were removed from service by plugging.

" All but one of the 11 TSP regions with indications above 2 volts was repaired by plugging. The one that was not plugged was not confirmed by MRPC examination. The tubes associated with these TSP regions were plugged because of MRPC-confirmed ODSCC at that particular support plate.

" A total of 17 of the 2747 TSP regions were removed from service for reasons other than MRPC-confirmed ODSCC at a support plate within the same tube.

Figure 3-1 through Figure 3-12 illustrate the voltage distribution in each steam generator. Figure 3-1 through Figure 3-4 show the detected voltage distribution compared to the predicted distribution which was developed in the previous 90-day report, Reference 5. Figure 3-5 through Figure 3-8 show the distribution of repaired indications, and Figure 3-9 through Figure 3-12 show the distribution of indications that remain in service for the next operating cycle.

EOC-14 Inspection Results March 2007 SG-CDMIE-07-7 Revision 1 10

3-2 As mentioned previously, the data includes 4 imputed voltages; these were cases where a bobbin indication was not identified, but a +Point indication was. The bobbin voltage, in these cases, was imputed by a comparison of bobbin and +Point voltages in intersections where a dent was not present. This comparison is provided in Figure 3-13. The upper 95% prediction bound was used to impute bobbin voltages from SAI +Point voltages. The 4 cases included one from SG 1, two from SG 2 and one from SG 3. All had imputed bobbin voltages between 1.53 V and 1.61 V.

3-20 3.2 VOLTAGE GROWTH RATES FOR CYCLE 14 Voltage growth was determined by the difference between the EOC-14 and EOC-13 voltages for each indication. The EOC- 13 voltages were determined by historical reviews of the prior cycle data base and were established using the same techniques as used to analyze the EOC- 14 data.

The voltage change is for the 537.1 EFPD cycle length of Cycle 14. The voltage at EOC-13 is provided for indications detected at EOC-14 in Appendix A.

The procedure for computing the voltage change and binning the values is described in Reference 3. Negative voltage changes are included in the 0 change bin. Voltage change distributions for each steam generator are included in Table 3-5 through Table 3-8. These tables also include the average percent change in voltage, obtained for each steam generator by dividing the average change in volts (from EOC-13 to EOC-14) by the average EOC-13 voltage.

A bounding EOC-14 specific growth rate distribution was used as defined in Table 3-9. A comparison of the steam generator specific growth rates and the EOC- 14 bounding growth rate is shown in Figure 3-14 and the tail end is shown in detail in Figure 3-15.

Figure 3-16 presents a comparison of the bounding growth rates from Cycle 13 with that from Cycle 14. The data has been normalized to a 1 EFPY basis (365.25 EFPD). Figure 3-17 provides a detailed view of the tail of the curve. From these figures it is shown that the growth rate in Cycle 14 bounds that from Cycle 13, thus the Cycle 14 growth rate is used in the projections.

Figure 3-18 presents a plot of the voltage growth as a function of the BOC voltage. A regression line of the data is also included. The R 2 value for the regression (0.0046) indicates that growth is not dependent on BOC voltage.

4-1 4.0 ANALYSIS METHODS AND DATA BASE FOR ARC CORRELATIONS A Monte Carlo based computer program was used to perform the calculations prescribed in GL 95-05 (Reference 1). The methodology for predicting the EOC voltage distribution and computing the probability of burst and leakage at accident conditions is based on the Westinghouse Topical Report, WCAP-14277, Revision 1 (Reference 3) supplemented by recent changes in the leakage computation process, discussed in Reference 8 as amended in Reference

9. The EOC voltage distribution, probability of burst and the leakage are computed using the Cyclesim3.1 program, Reference 10.

The predictions for EOC-14 recorded in Reference 5 used the tube burst and leakage correlations of Addendum 6 to EPRI Report NP-7480-L modified according to References 8 and 9. Both the condition monitoring assessment for EOC- 14 and the operational assessment predicting the EOC-15 voltage distribution are also performed using the Addendum 6 database (Reference 6).

Since Sequoyah Unit 2 can take credit for PORV actuation, the condition monitoring and operational assessments are performed using the leakage correlation for 2405 psi (Reference 2).

The specific parameters used in the correlations are provided in Sections 4.1 through 4.4.

4.1 TUBE MATERIAL PROPERTIES The tube material properties are provided in Table 4-1 of Reference 3 for 7/8-inch diameter tubes at 650'F. The parameters used in the analysis are the flow stress mean of 68.78 ksi and the flow stress standard deviation of 3.1725 ksi.

Analysis Methods and Data Base for ARC Correlations March 2007 SG-CDME-07-7 Revision I 40

4-2 4.2 BURST CORRELATION The burst pressure, Pb, is normalized to a material with a flow stress of 68.78 ksi, which is the mean of the 7/8-inch tube data appropriate for Sequoyah Unit 2. The correlation parameters shown in Table 4-1 below are taken from Reference 6.

Notes: (1) Values reported correspond to applying a safety factor of 1.4 on the differential pressure associated with a postulated SLB event.

(2) Numerical values are reported only to demonstrate compliance with the requirement that the value be less than 0.05.

(3) This is the flow stress value to which all data were normalized prior to performing the regression analysis. This affects the coefficient and standard error values. The corresponding values for a flow stress of 75.0 ksi can be obtained from the above values by multiplying by 1.0904.

4.3 LEAK RATE CORRELATION The leak rate correlation as a function of indication voltage is taken from Reference 6. The steam line break pressure is given as 2405 psi in Reference 2. Therefore the leak correlation for pressure of 2405 psi from Reference 6 is used for the leakage predictions. The parameters are shown in Table 4-2.

4.5 NDE UNCERTAINTIES The NDE uncertainties applied for the EOC-14 and EOC-15 voltage projections are the same as used in the previous 90-day report, Reference 5, and described in Reference 3. The probe wear uncertainty has a standard deviation of 7% about a mean of zero and has a cutoff 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 cutoff. These NDE uncertainty distributions are used in the Monte Carlo analysis to predict the burst probabilities and accident leak rates at EOC-14, and EOC-15. 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 The upper voltage repair limit is based on the structural limit in Table 4-1 of 7.51 volts for an accident pressure of 2560 psi. It must be reduced by considering the projected voltage growth during the next cycle and NDE uncertainty. The maximum average percentage growth rate for any steam generator is seen from Table 3-8 (SG 4) to be 21.2% for the 537.1 EFPD Cycle 14, which would project to 21.2% x (481/537.1) = 19% for the anticipated 481 EFPD Cycle 15.

According to Reference 1, the minimum growth adjustment is 30% per EFPY (39.5% per cycle for the anticipated 481 EFPD Cycle 15). Therefore the specific maximum growth value of 39.5%

Analysis Methods and Data Base for ARC Correlations March 2007 SG-CDME-07-7 Revision 1 43

4-5 and 20% for NDE uncertainty was used to estimate the voltage repair limit. This results in an upper voltage repair limit of 7.51 / (1 + 0.395 + 0.20) = 4.71 volts. No indications equal to or greater than this voltage were left in service.

4.7 PROBE WEAR An alternate probe wear criteria, approved by the NRC (Reference 7), was applied during the EOC-14 inspection. When a probe does not satisfy the +/-15% voltage variability criteria for wear, this alternate criteria requires that all tubes that have indications above 75% of the repair limit inspected since the last successful probe wear check be reinspected with a good probe. All probes that failed the wear check were immediately replaced with a new probe. In accordance with this alternate probe wear criteria, the whole tube was re-inspected with a good probe when any part of the tube exceeded 75% of the repair limit. As the repair limit for Sequoyah-2 is 2 volts, all tubes that contained worn probe indications above 1.5 volts were re-inspected with a new probe. In the cases where the original call made with the worn probe was greater than 1.5 volts, the signal amplitude obtained with the new probe was used in these analyses.

A total of 12 indications (in 11 tubes) with a bobbin DSI voltage above 1.5 volts were found in the calibration groups that failed the probe wear check (these indications were called as 'RPW'),

and the tubes containing those indications were reinspected with a new probe. The tubes and the RPW and subsequent DSI voltage are shown in Table 4-4. Some of these retested tubes also had indications with DSI volts less than 1.5, and the retest values of those is also shown in the table.

Of the three new indications that were detected on retest, only one was a significant voltage (1.03 volts).

4-6 Figure 4-1 shows the good probe voltages plotted against the worn probe voltages for all four SGs. No indication that was measured with a worn probe to have a voltage below the repair limit had its voltage increase above the repair limit when reinspected with a good probe. This observation supports the criterion that says that these indications did not need retesting.

Figure 4-1: Retest Voltage vs. First Test Voltage of Indications Originally Measured with Worn Probe The indications found in the current inspection that were tested with a worn probe in the previous (2005) inspection were identified. A summary of these results are given in Table 4-5 through Table 4-9 and Figure 4-2 through Figure 4-5. The similarity of the distribution of DSI voltages for new indications in tubes tested with worn probes in 2005 and new indications in tubes tested with good probes in 2005 demonstrates that these two groups of indications are from the same population.

4-16 The indications found in the current inspection that were tested with a worn probe in the previous (EOC-13) inspection were identified as seen in the tables above. Of the 586 indications found in the current inspection that were tested with a worn probe in the previous inspection, only two were 2 volts or greater. Of the 1240 indications found in the current inspection that were tested with a good probe in the previous inspection, six were 2 volts or greater. Therefore there is no significant difference in the proportion of repairable indications for tubes previously tested with a worn probe.

As required by the NRC letter to the Nuclear Energy Institute dated February 9, 1996 (Reference 7), the number of new indications detected in the present inspection in tubes that were inspected with a worn probe in the last inspection was also determined. Out of a total of 925 new indications reported in the current inspection, 331 were in tubes inspected with a worn probe during the last inspection. SG 4 has the highest number of indications and the highest ratio of new indications that were identified in tubes tested with a worn probe in EOC- 13 to the number of tubes tested with a worn probe in EOC- 13 of 0.13. The ratio of new indications that were identified in tubes tested with a good probe in EOC- 13 to the number of tubes tested with a good probe in EOC-13 for SG 4 is 0.10. The percentage of new indications equal to or greater than 0.5 V in tubes tested with a worn probe in SG 4 is 5 8.2%, and the percentage of new indications equal to or greater than 0.5 V in tubes tested with good probe in SG 4 is 59%. The similarity of these ratios and percentages indicate that there is no significant difference in the rate of occurrence or magnitude of new indications found in the EOC- 14 inspection due to testing with a worn probe in the EOC- 13 inspection. Thus, the requirements specified for applying the alternate probe wear criteria are met.

5-1 5.0 CONDITION MONITORING: TUBE LEAK RATE AND BURST PROBABILITIES AT EOC-14 5.1 ANALYSIS APPROACH The measured EOC-14 voltage distributions of Table 3-1 through Table 3-4 for each steam generator are used as the basis for the leak rate and burst probability predictions for EOC- 14.

The voltage distributions developed for the computation of POB and leakage consider NDE uncertainty on the measured values, but consider no voltage growth. The resulting voltage distributions used for computation of the probability of burst and leakage are given in Figure 5-1 through Figure 5-4.

5-6 5.2 EOC-14 BURST PROBABILITIES AND LEAK RATES The Monte Carlo analysis results for each of the steam generators based on the measured voltage distribution at EOC- 14 are shown in Table 5-1. One-quarter-million Monte Carlo trials were performed for each steam generator. The leakage rate is the 95th percentile evaluated at 95%

confidence. The burst probability is 95% confidence based on the number of trials. Table 5-2 presents the predicted results from Reference 5.

The acceptance criteria on POB and leakage are satisfied with significant margin.

The predicted values for the probability of burst and leakage are conservative. They are based on the very conservative database provided in Reference 6. The number of indications and maximum voltages were conservatively predicted.

5-7 The total number of measured indications for each steam generator was less than the predicted total number of indications, except for SG2. SG 2 had 507 axial TSP indications compared to a projected number of 501.3 indications. This minor difference between the actual and projected number of indications was not attributable to tubes tested with a worn probe, as was shown in Section 4.7. As Figure 3-1 through Figure 3-4 shows, the quantity of the smaller voltage indications was underestimated but the quantity of larger voltage indications was overestimated.

This is attributable to the 0.6 POD (for all indications, regardless of size) that was used to develop the predictions. The larger voltage indications have a greater impact on the leakage prediction values and the burst probability, thus the leakage and burst values were overestimated.

6-1 6.0 OPERATIONAL ASSESSMENT: TUBE LEAK RATE AND BURST PROBABILITIES AT EOC-15 6.1 ANALYSIS APPROACH The BOC- 15 voltage distributions are developed, within the Cyclesim3.1 program, from the measured EOC-14 distribution by considering the POD and the indications that are removed from service. The EOC-15 voltage distribution is developed considering the NDE uncertainties and voltage growth during the cycle. The Cycle 14 growth rate was used in these projections, since it bound the Cycle 13 growth rate. The latest burst and leakage correlations, Reference 6, are used for the EOC-15 predictions. The burst probabilities and leak rates are computed using the computed EOC- 15 voltage predictions to address the acceptance criteria at the end of the cycle.

6.2 POD The POD used is the NRC accepted value of 0.6 for all voltages (Reference 1). The beginning of Cycle 15 (BOC-15) voltage distributions are shown in Table 6-1.

The Cycle 14 growth rate is used in these projections.

6.4 PREDICTION OF VOLTAGE DISTRIBUTIONS AT EOC-15 The prediction of the EOC-15 voltage distributions is based on the BOC-15 indications and the composite growth rate. The length of Cycle 15 is established at 481 effective full power days (EFPD), Reference 2. The EOC-15 predicted voltage distributions (using the Cycle 14 growth rate) are shown in Table 6-2 and in Figure 6-1 through Figure 6-4.

One-quarter-million Monte Carlo trials were performed for each steam generator in this operational assessment. The Cycle 14 growth rate was used for these predictions. The leakage rate is the 95 t percentile evaluated at 95% confidence. The burst probability is 95% confidence based on the number of trials.

All OD indications were either above the top-of-tubesheet and or above the associated Bottom of the Wextex Transition (BWT) and therefore not included.

All indications of Primary Water Stress Corrosion Cracking (PWSCC) at the top-of-tubesheet were included in the Condition Monitoring W* leakage evaluation regardless of whether or not they were above the BWT. The location of upper crack tip was subtracted for the location of the BWT and then this value had the NDE uncertainty subtracted. If the value was negative, it was then assumed to be zero.

The Condition Monitoring assumed leakage was determined for each SG. To determine the Condition Monitoring leakage assumed in the 0" to 8" below the BWT region for each of the SGs, the indications were binned into the following bins; 0 to 1, 1 to 2, 2 to 3, and 3 to 4, etc. The leakage value for each of the bins was obtained from WCAP-14797, Rev 2, Figure 6.4-3. The quantity of indications in each bin was multiplied by the greatest leakage value for the bin (i.e., the 1 to 2 inch bin was multiplied by the 1 inch below the BWT leakage value from the Figure 6.4-3). The leakage value for the bins was summed to obtain the total in the 0" to 8 below the top of tubesheet region. To determine the Condition Monitoring assumed leakage in the 8 inch to 12 inch below the HTS region, the total historical count of indications 0 inches to 8 inches below the TTS from all four SGs plus the number of detected indications 0 inches to 8 inches below the TTS for all four SGs for the present outage were combined and 25% of this total was applied to each of the four SGs to determine the assumed quantity of indications in the 8 inches to 12 inches below the TTS region. This assumed quantity of indications was multiplied by 0.0045 gpm to obtain the 8 inches to 12 inches below the TTS leakage. To determine the Condition Monitoring assumed leakage in the greater than 12 inch below the HTS region, the quantity of tubes in service in the specific SG was used. This quantity of tubes was multiplied by 0.00009 gpm to obtain the W* leakage for the greater than 12 inch below the HTS region for each SG.

Operational Assessment assumed leakage was determined for a faulted SG. To determine the Operational Assessment assumed leakage in the 0' to 8" below the TTS region, an assumed quantity of undetected indications was determined by utilizing the largest quantity over all four SG of indications in each of the bins (0 to 1", 1" to 2", 2" to 3", and 3" to 4", etc) and dividing that greatest bin quantity by 0.6 (assumed POD) and subtracting the quantity of tubes plugged. The leakage value for each of the bins was obtained from WCAP- 14797, Rev 2, Figure 6.4-3. The quantity of indications in each bin was multiplied by the greatest leakage value for the bin (i.e., the 1 to 2 inch bin was multiplied by the 1 inch below the BWT leakage value from the Figure 6.4-3). The leakage value for the bins was summed to obtain the total in the 0" to 8 below the top of tubesheet region. To determine the Operational Assessment assumed leakage in the 8 inch to 12 inch below the HTS region, the total historical count of indications 0 inches to 8 inches below the "ITSfrom all four SGs plus the number of projected indications 0 inches to 8 inches below the TTS for all four SGs for the upcoming fuel cycle was combined and 25% of this total determined the assumed quantity of indications in the 8 inches to 12 inches below the TTS region for the faulted SG. This assumed quantity of indications was multiplied by 0.0045 gpm to obtain the 8 inches to 12 inches below the TTS leakage. To determine the Operational Assessment assumed leakage in the greater than 12 inch below the HTS region, the quantity of tubes in service in the least plugged SG was used. This quantity of tubes was multiplied by 0.00009 gpm to obtain the W* leakage for the greater than 12 inch below the HTS region for the faulted SG.

The circumferential indication had a Max Volts less than 0.5 which the EPRI In-Situ Pressure Test Guidelines states preclude burst. The two axial indications are so deep with the tubesheet that burst is also precluded.

W* Inspection Assessment W* Alternate Repair Criteria requires an assessment be performed to determine whether the results of the inspection were consistent with the expectations. These expectations are with respect to the number of flaws and flaw severity. The quantity of flaws found in the 4" to 8" regions below the top of the tubesheet is expected to be less than 25% of the total number of flaws. Table 2 is a listing of the PWSCC top-of-tubesheet indications subject to the W* assessment. Also, an assessment is required to be performed for whether W* identified newly initiated severe indications of cracking and if so include their potential leakage rate in the assessment.

Seventeen W* region indications were predicted to be discovered during the U2C14 inspection. A total of three PWSCC top-of-tubesheet indications were detected (in two tubes) in the W* region. Two of the three indications (in tube SG4 R4 C25) are located greater than eight inches below the top of the tubesheet. The other indication is located 0.11 inches below the hot leg top-of-tubesheet and above the Bottom of the WEXTEX Transition (BWT). Zero indications were therefore discovered in the 4" to 8" region. TVA utilized a linear regression of the total quantity of indications since U2C8 and predicts that 25 W* region indications will be detected during the next inspection (U2C1 5).

The following is an assessment of the severity of the flaws. The only PWSCC HTS Circumferential indications detected U2C14 were within an inch of the top-of-tubesheet. Sizing of this indication was not performed because the Max. Volts was less than 0.5 volts (EPRI, Steam Generator In-Situ Pressure Test Guidelines Revision 2, Section B.3.4 states that 0.5 Plus Point volts precludes a tube from bursting at 3mP).

The quantity of circumferential indications (one) detected U2C14 is less than the two circumferential 3

indications detected U2C13, the four circumferential indications detected U2C12 and the six circumferential indications detected U2C 11. There is a definite downward tread in circumferential indications over the last four outages. Also, the fact that the Max. Volts is below the quick screen for In-Situ Pressure Testing indicates that the past detection and/or crack growth rate is acceptably low and therefore flaw severity is acceptably low. The axial indications greater than eight inches below the top-of-tubesheet were also not sized because of their upper most crack tip being greater than eight inches below the top-of-tubesheet.

SQN Unit 2 eddy current examinations of the hot leg top-of-tubesheet had a minimum depth of 8 inches below the top-of-tubesheet. The vendors examined a greater extent (typically one or two inches) in order to ensure the minimum 8 inches was achieved. Because of this, the two axial indications greater than eight inches below the top-of-tubesheet were detected. Because only two indications were identified, TVA believes that this provides some assurance that the methodology for predicting the quantity of indications in the 8" to 12" below the top-of-tubesheet is conservative.

Based on the preceding information, none of the top-of tubesheet indications were categorized as severe and therefore no changes were made to include additional leakage in the leakage model for W*.

Based on the above, it is concluded that the severity of flaws and quantities of flaws are consistent with the expectations for indications within the W* distance.

The SQN Unit 2 primary to secondary leakage limit during the postulated MSLB accident is 3.7 gpm. The Table 1 leakage value is below this limit and therefore acceptable.
