SG-SGDA-03-55, Rev. 0 Page 4 of 95 1.O Introduction Sequoyah Unit 2 completed the twelfth cycle of operation and subsequent steam generator tube inspection in November 2003. 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) has been implemented at Sequoyah Unit 2 for several operational cycles (References 2, 3, 4, 5, 6).

This report provides a condition monitoring assessment that demonstrates that the GL 95-05 acceptance criteria are satisfied at the end of operational cycle 12 (EOC-12), and an operational assessment that demonstrates that the GL-95-05 acceptance criteria is expected to continue to be satisfied throughout operational cycle 13.

The operation cycle just completed, cycle 12, was 501.6 Effective Full Power Days (EFPD). The next cycle, cycle 13, is estimated to be 498.0 EFPD (Reference 7).

SG-SGDA-03-55, Rev. 0 Page 5 of 95 2.0 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 References 1 and 8 and the correlation data of Reference 9, 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-12 was performed. The acceptance criteria on POB and leakage are satisfied with significant margin. The number of indications detected was greater than predicted in the three SGs with the smaller number of indications, and the number of indications detected was less than predicted in the SG with the largest number of indications. The total number of indications was conservatively predicted. One large voltage indication of 9.76 volts in SG 3 exceeded the predicted maximum voltage. The maximum was conservatively predicted in the other three SGs. The probability of burst computed for all SGs was greater than the prediction, but still below the allowable value. This is due in large measure to the change in burst correlation used in the current analysis from the correlation used in the prediction. The leakage was conservatively predicted. The leakage results remain well within allowable limits.

For each indication detected, the change in voltage from the previous inspection was determined by historical review. The apparent growth rate per EFPY was determined for each steam generator, and was not significantly different from the apparent growth during cycle 11 except for the long tail caused by the growth of the 9.76 volt indication.

Since there were not significant differences in the voltage growth rates among the steam generators, except for the tail due to the one large indication, a bounding growth rate was selected to be used for all SGs which envelopes the growth used for the predictions for cycle 12 and the growth measured in cycle 12 for the operational assessment prediction for EOC-13. The prediction of the PO6 and leakage at steam line break conditions at EOC-13 was performed. The results indicate that the acceptance criteria of Reference 1 on POB and leakage at EOC-13 will continue to be satisfied.

SG-SGDA-03-55, Rev. 0 Page 6 of 95 3.0 EOC-12 Inspection Results 3.1 Voltage Distributions at EOC-12 A summary of eddy current signal voltage distributions at the drilled support plates for all steam generators is shown in Tables 3.1 through 3.4 for steam generators 1 through 4 respectively. The full EOC-12 indication list is provided in Appendix A. These tables show the number of indications in each voltage range detected at EOC-12, 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 13 is the difference between the number detected and the ones removed from service. No tubes were unplugged with the intent to return them to service after in specti on.

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

0 A total of 1545 bobbin signals were identified as TSP indications during the inspection which were called DSls.

0 Of the 1545 DSls, six (6) were equal to or greater than 2 volts.

0 The tubes with indications greater than 2 volts were plugged due to ODSCC at the support plates.

26 other indications were plugged preventatively or for reasons other than ODSCC at the support plates.

Figures 3.1 through 3.4 show the voltage distribution of indications returned to service. Figure 3.5 shows the voltage distribution of the indications repaired.

SG-SGDA-03-55, Rev. 0 Page 16 of 95 3.2 Voltage Growth Rates for Cycle 12 The voltage growth for each indication detected at EOC-12 was determined by identifying the corresponding voltage at the previous inspection, EOC-11. The following process was used to determine the EOC-11 voltage:

0 If the indication was called a DSI at EOC-11, then the reported voltage is used.

0 If the indication was not called a DSI at EOC-11, then a re-evaluation of the historical data of the corresponding EOC-11 inspection result was made, 0

If the re-evaluation of the historical data did not detect an indication, then the previous cycle voltage was assumed to be 0.0 volts.

The distribution of voltage differences over the entire 501.6 EFPD cycle is shown in Table 3.5 for all four steam generators. A comparison of the growth rates for each steam generator on an EFPY basis is determined by dividing by the EFPY of Cycle 12. This comparison is shown in Figure 3.6a in the range of volts per EFPY <I.O in order to see the small differences. The extended tail of the growth for SG3 and SG4 due to the two largest voltage indications is shown in Figure 3.6b Also shown in Figures 3.6a and b is the Cycle 12 bounding curve, which bounds the growth for all four steam generators.

Volts per EFPY The voltage growth rates in volts per EFPY for all of the steam generators are shown in Table 3.6. The average growth rate is developed by computing the average voltage of all indications in a specific SG at BOC-12 and the average voltage of all indications in the same SG at EOC-12. The difference divided by the average at BOC-12 divided by the EFPY of cycle 12 times 100 is the average percent growth per EFPY. The one high voltage growth (change from 1.98 volts to 9.76 volts) indication in SG 3 results in an extended tail to the growth data.

This will be addressed in Section 4.

Steam generators SGI, SG2, and SG3 have more indications than predicted. Steam generator SG4, the SG with the largest number of indications has less than predicted. In all steam generators except SG 3, the maximum measured voltage is lower than the prediction.

Table 6.1 Predicted Results for EOC-12 from Reference 6

  • Note: The maximum voltage is defined as the voltage where the integration of the voltage distribution from the tail reaches 0.3 of an indication.

The Monte Carlo analysis results for each of the steam generators based on the measured voltage distribution at EOC-12 are shown in Table 6.2. Two hundred and fifty thousand Monte Carlo trials were performed for the burst and leakage predictions for each steam generator. The leakage rate is the 9fjth percentile evaluated at 95% confidence. The burst probability is the probability of burst of one or more tubes at 95% confidence based on the number of trials.

Table 6.2 Monte Carlo Analysis Results for Measured EOC-12 Voltage Distributions 6.3 Comparison with Acceptance Criteria The results indicate that the leakage predictions for EOC-12 were conservative for SGI,SG2, and SG4. The leakage result for SG3 was slightly greater (3%)

than predicted. The numbers of indications for SGI, SG2 and SG3 are greater than predicted, and the number of indications for SG4 is less than predicted. The total number of indications detected is less than the total number predicted. The POB for SGI, SG2, and SG4 are slightly higher than predicted, which is expected because of the database changes. The larger than predicted maximum voltage indication of SG3 resulted in a significant increase in POB compared to the prediction, but still less than the allowable value. All steam generators are below the burst acceptance criterion of 1.O x and the Sequoyah Unit 2 leakage criterion of 3.7 gpm. Therefore the acceptance criteria on POB and leakage continue to be satisfied.

SG-SGDA-03-55, Rev. 0 Page 41 of 95 7.0 Operational Assessment:

Tube Leak Rate and Burst Probabilities at EOC-13 7.1 Analysis Approach The BOC-13 voltage distribution is developed from the measured distribution by considering the POD and the indications that are removed from service. The EOC-13 voltage distribution is developed considering the NDE uncertainties and voltage growth during the cycle. The latest burst and leakage correlations, Reference 9, are used for the EOC-I 3 predictions. The burst probabilities and leak rates are computed using the computed EOC-13 voltage predictions to address the acceptance criteria at the end of the cycle. Calculation details are documented in Reference 13.

7.2 BOC Voltage Distribution The BOC-13 voltage distribution for each steam generator is determined from the measured EOC-12 voltage distribution. First, the number of indications potentially missed during the inspection and the number of new indications initiating during the Cycle 13, are considered by dividing the measured number of indications in each voltage range by the assumed POD. From this number of indications in each voltage range is subtracted the number of indications removed from service for any reason. This then gives the BOC-13 voltage distribution.

7.2.1 POD The POD used is the NRC accepted value of 0.6 for all voltages (Reference 1).

7.2.2 Tube Repairs Considering the repaired tubes and the POD, the BOC-13 voltage distribution for each SG is given in Table 7.1

Volts 7.5 Prediction of Tube Leak Rates and Burst Probabilities at EOC-13 The POB and leakage analysis results for predicted EOC-13 voltage distributions are shown in Table 7.4. Two hundred and fifty thousand Monte Carlo trials were performed for the burst and leakage prediction for each steam generator. The leakage rate is the 9!jth percentile evaluated at 95% confidence. The burst probability is the probability of burst of one or more tubes at 95% confidence based on the number of trials. Calculation details are documented in Reference
