1.0 INTRODUCTION

During the Sequoyah Unit 2 (SQN2) Spring 2011 refueling outage (designated as 2C 17), extensive inspections of the SQN2 steam generators (SGs) were performed. These inspections included eddy current inspections of all in-service tubes as well as secondary side visual inspections.

Numerous acronyms are used throughout this report. Table 1-1 provides a list of these acronyms.

A Document No.: 51-9171130-001 AR EVA Sequoyah 2C17 180-Day Steam Generator Inspection Report 2.0 180-DAY STEAM GENERATOR INSPECTION REPORT In accordance with SQN2 Technical Specification 6.8.4.K, "Steam Generator Program", and Technical Specification 6.9.1.16, "Steam Generator Tube Inspection Report", this report documents the scope and results of the 2C 17 steam generator inspections. This report is required to be submitted to the NRC staff within 180 days after entering Mode 4 following completion of a steam generator inspection.

There are eight specific reporting requirements (labeled "a" through "h" below). Each reporting requirement is followed with the required information based on the inspections performed during the 2C 17 outage.

a. The Scope of the Inspections Performed on Each SG The 2C17 outage included eddy current inspections of all in-service steam generator tubes. All in-service tubing was inspected with the bobbin coil with the exception of the u-bends of Rows 1 through 10. The u-bends of Rows 1 through 10 were inspected with array or +PointTM coils. The hot leg tubesheet region of all in-service tubes was inspected with +PointTM for a minimum inspection extent of HTS +2" to -8". Twenty percent of the in-service tubes were inspected in the cold leg tubesheet region for a minimum inspection extent of CTS +2" to -10.5". Other +PointTM inspections were performed on locations of special interest based on the results of the bobbin inspection. Table 2-1 provides the number of inspections performed for each examination plan.

The 2C 17 steam generator inspection also included visual inspections of all previously installed plugs. This included both mechanical and welded plugs.

Secondary side visual inspections were also performed at the top of the tubesheet. These inspections were focused on investigating locations of previously identified foreign objects left in the steam generators and other locations identified by eddy current during the 2C 17 inspection as having foreign object wear or PLP (Potential Loose Part) signals.

b. Active Degradation Mechanisms Found Based on the inspections performed, several degradation mechanisms were reported. Table 2-2 provides a summary of the degradation mechanisms reported. The numbers in this table indicate the number of indications reported (i.e., not the number of tubes affected).

e. Number of Tubes Plugged During the Inspection Outage for Each Active Degradation Mechanism Table 2-4 below provides the number of tubes plugged for each degradation mechanism. This table also provides the number of tubes plugged prior to and after the 2C 17 outage as well as the percentage of tubes plugged after the 2C 17 outage.

f. Total Number and Percentage of Tubes Plugged to Date Table 2-4 in the previous section provides the number and percentage of tubes plugged to date.

g. The Results of Condition Monitoring, Including the Results of Tube Pulls and In Situ Testing Each degradation mechanism observed during the 2C 17 inspection is discussed below relative to condition monitoring and screening for in situ test candidates. The limiting structural integrity performance criterion for SQN2 is three times the normal operating pressure differential. Based on the normal operating pressure differential of 1397.2 psid, the 3AP value used in the condition monitoring assessment was 4192 psid.

AVB WEAR The Sequoyah Unit 2 Cycle 17 Degradation Assessment predicted, based on past indications and growth rate data, that three tubes would exceed the plugging limit for AVB wear. A total of 93 indications (in 47 tubes) were detected. None exceeded the plugging limit of 40%. The 40% plugging limit is conservative for Sequoyah Unit 2 SGs for both structural integrity and accident induced leakage performance criteria.

Condition monitoring assumed the axial length of the AVB wear indication to be greater than the width of the AVB (i.e., 0.53" vs. actual width of 0.38"). The condition monitoring (CM) limit for an AVB wear flaw with an axial extent of 0.53" is greater than 60%TW. Since the maximum depth reported was 38% throughwall (TW), condition monitoring requirements were met for AVB wear.

Cold Leg Thinning A total of 248 indications (in 237 tubes) of cold leg thinning were detected. Four indications exceeded the repair limit of 40% through wall and were plugged. The 40% repair limit is conservative for SQN Unit 2 SGs for structural and leakage performance criteria. Condition monitoring assumed the axial length of cold leg thinning to be the tube support plate thickness (0.75"). The maximum depth reported for cold leg thinning was 44%TW. The CM limit for a cold leg thinning flaw assuming uniform thinning with a length of 0.75" is greater than 50%TW. Therefore condition monitoring requirements were met for cold leg thinning.

Foreign Obiect Wear No new indications attributed to foreign object wear were detected during the U2C17 inspection. One previously reported indication believed to have been caused by a foreign object was reported again in SG23.

This indication had a voltage of 0.19v and an estimated depth of 32%TW using EPRI ETSS 27903.1. Based on its low voltage response and estimated depth, this indication met the condition monitoring structural and leakage performance criteria.

Due to the facts that 1) this indication has been present since at least 1994 with little change, 2) the foreign object that presumably caused the wear is no longer present, and 3) the indication measured <40%TW with a qualified sizing technique, the tube with this indication (R37-C65) was returned to service for Cycle 18.

A Document No.: 51-9171130-001 AREVA Sequoyah 2C17 180-Day Steam Generator Inspection Report Axial ODSCC in Freespan Regions Nineteen indications of axial ODSCC in freespan regions were identified in six tubes during the 2C 17 inspection. With two exceptions, all indications were at or below the 0.4 volt quick screen for structural or leakage evaluation. The 0.4 quick screen is based on Reference 1 , Section B.3.4, which states that the

+PointTM 0.4 volt quick screen value precludes a tube from bursting at 3 x NOPD and therefore eliminates the need to perform NDE sizing or in situ pressure testing. In addition, Reference 1 says that, to be considered for additional in situ screening, the length of the flaw exceeding 0.4v must be >0.6". Neither of the two indications that exceeded the 0.4v criterion were over 0.4v for a length of >0.6". These indications were also well below the initial voltage threshold (2.21v) for leakage screening. Therefore, the condition monitoring structural and leakage performance criteria were met for axial ODSCC at freespan locations.

All tubes with indications of axial ODSCC at freespan locations were plugged.

Axial ODSCC Near the Top of the Hot Leg Tubesheet A total of six indications in five tubes were identified as axial ODSCC near the top of the hot leg tubesheet.

All but one of these indications were below the 0.4 volt quick screen for performing structural or leakage analysis. As discussed above for axial ODSCC in the freespan, the length of the flaw exceeding 0.4v must be

>0.6" to be considered for additional structural screening. The indication that was greater than 0.4v (SG23 tube Rl19 C48) was only 0.18" long and, therefore, didn't need additional screening based on depth and length. Also, this indication had a maximum voltage of 0.94v, which is below the EPRI voltage threshold of 1.Ov for additional consideration for leak testing for axial ODSCC indications at explosive transitions.

Therefore, all axial ODSCC indications near the top of the hot leg tubesheet met the condition monitoring performance criteria.

All tubes with axial ODSCC near the top of the tubesheet were plugged.

Circumferential ODSCC Near the Top of the Hot Leg Tubesheet A total of ten indications in nine tubes were identified as circumferential ODSCC near the top of the hot leg tubesheet. Each of these indications was below the 0.5 volt quick screen for performing structural or leakage integrity for circumferential indications. The 0.5 quick screen is based on Reference 1, Section B.3.4, which states that the +PointTM 0.5 volt quick screen value precludes a tube from bursting at 3AP and, therefore, eliminates the need to perform NDE sizing or in situ pressure testing. The voltages of these indications were also below the EPRI voltage threshold of 1.33v for additional consideration for leak testing for circumferential ODSCC indications at explosive transitions. Therefore, all circumferential ODSCC indications near the top of the hot leg tubesheet met the condition monitoring performance criteria.

All tubes with circumferential ODSCC indications near the top of the hot leg tubesheet were stabilized and plugged.

A Document No.: 51-9171130-001 AREVA Sequoyah 2C17 180-Day Steam Generator Inspection Report Axial ODSCC at TSPs Most axial ODSCC indications at tube support plates (TSPs) are allowed to remain in service under an approved alternate repair criterion (NRC Generic Letter 95-05; Reference 2). Under the alternate repair criterion, TSP intersections with suspected or confirmed ODSCC are allowed to remain in service if the indications meet certain criteria. As required by Reference 2, a detailed condition monitoring and operational assessment was transmitted to the NRC with 90 days of initial entry into Mode 4. This assessment is documented in Reference 3 and was provided to the NRC as an enclosure to Reference 4. The condition monitoring probability of burst in the limiting steam generator at the end of Cycle 17 was 1.42E-4 and the postulated accident induced leakage due to ODSCC at TSPs in the limiting steam generator at the end of Cycle 17 was 0.427 gpm. These values meet the performance criteria as discussed in Reference 3.

During the 2C 17 inspection, the largest bobbin voltage for an axial ODSCC at TSP indication was 3.08v. The upper voltage repair limit (which includes a growth component in addition to eddy current uncertainties) for 2C17 was 5.91v (Reference 3). Therefore, condition monitoring was met.

Fourteen tubes required plugging due to axial ODSCC at TSPs during the 2C17 outage. Per the ARC, bobbin indications greater than 2.0 volts that were confirmed as axial ODSCC with +PointTM were plugged. An additional five tubes with axial ODSCC at TSPs were plugged "preventively" to prevent extreme voltage growth.

Circumferential ODSCC at Dented TSPs During the 2C 17 outage, three indications of circumferential ODSCC at TSPs were detected. These indications were all at the 7 th TSP on the hot leg side in adjacent tubes in SG21. Two of the three indications were below the initial 0.5v screening threshold for circumferential indications. The third indication had a measured voltage of 0.59v. Therefore, additional screening was required for this flaw. Section 4.4.2.2 of Reference 1 provides an initial conservative screen on crack angle for circumferential flaws. Per Reference 1, if the crack angle measures < 180 degrees, a proof test is not required. With a measured crack angle of 134 degrees, this indication also meets the performance criterion for structural integrity.

The EPRI In Situ Guidelines (Reference 1) provide no threshold voltage for leakage screening for circumferential ODSCC at TSPs. However, the maximum voltage reported at 2C 17 (0.59v) is well below any of the voltage thresholds provided (including circumferential ODSCC at other locations with geometric deformation). Based on the circumferential extent and the voltage of this flaw, condition monitoring was considered to be met.

These three tubes were plugged and stabilized.

A AREVA Document No.: 51-9171130-001 Sequoyah 2C17 180-Day Steam Generator Inspection Report Axial PWSCC Near the Top of the Hot Leg Tubesheet One indication of axial PWSCC near the top of the hot leg tubesheet was identified. This indication was less than the quick screen value of 0.4 volts for axial indications. The voltage of this indication was also the initial voltage threshold (2.50v) for leakage screening. Therefore, the condition monitoring structural and leakage performance criteria were met for axial PWSCC near the top of the hot leg tubesheet.

This tube was plugged.

Circumferential PWSCC Near the Top of the Hot Leg Tubesheet One indication of circumferential PWSCC was identified near the top of the hot leg tubesheet. This indication had a +PointTM voltage of 0.83v. This exceeded the 0.5 volt initial screen for circumferential cracking and, therefore, required further evaluation. This flaw was depth and length sized as 49%TW maximum depth and 23 degrees in circumferential extent. Therefore, this flaw is well below the condition monitoring limit of 50.7 PDA (Percent D6graded Area) from the SQN2 Degradation Assessment [5]. The flaw did not exceed the voltage threshold (1.38v) for additional leakage screening. Therefore, this indication met the condition monitoring structural and leakage performance criteria.

This tube was plugged and stabilized.

Axial PWSCC in U-bend Regions Two indications of axial PWSCC in low row u-bends were detected. One of these indications, in SG 22 R1C54, measured 1.37V with +PointTM. This indication passed the structural integrity screening based on its short length (0.18"). However, the voltage exceeded the EPRI leak test screening criterion of 1.31 v and had a maximum measured depth of 99%TW and was, hence, at a small risk for experiencing "pop-through" leakage. Therefore, this flaw was in situ tested per the requirements of Reference 1. The flaw did not leak or burst in situ pressure testing.

The other flaw, in SG23 R1C37, measured 0.58v with +PointTM. This flaw passed the structural screening based on its measured length (0.22") being less than the allowable length (0.44") for a throughwall axial flaw

[5] and passed leakage screening based on voltage.

Both of the tubes with axial PWSCC in the u-bends were plugged.

Page 16

A Document No.: 51-9171130-001 AREVA Sequoyah 2C17 180-Day Steam Generator Inspection Report Axial ODSCC in U-bend Regions Two indications of axial ODSCC were detected in the u-bend of a Row 12 tube. Both of these indications were detected with bobbin. Both of these indications were below the initial 0.4v screening value for structural integrity. These indications were, therefore, also both below the threshold voltage of 1.0v for leakage screening. Both of these indications met the condition monitoring structural and leakage performance criteria.

This tube was plugged.

Circumferential PWSCC in U-bend Regions One indication of circumferential PWSCC was detected in a Row 6 u-bend. This indication exceeded the initial 0.5v screening for structural integrity and was, therefore, depth and length sized. With a maximum measured depth of 97%TW and a crack angle of only 35 degrees, this flaw is well below the condition monitoring limit of 50.7 PDA (percent degraded area). In addition, the voltage of this flaw is well below the threshold for leakage screening of 1.98v. Therefore, the condition monitoring structural and leakage performance criteria were met for this mechanism.

This tube was plugged and stabilized.

Axial PWSCC at Dented TSPs Four indications of axial PWSCC at dented TSPs were reported during the 2C 17 outage. Three of the four indications exceeded the initial 0.4v screening threshold for axial indications. However, none of the indications exceeded 0.4v over a length >0.6v. Thus, the structural integrity performance criterion was met.

The largest voltage was 1.Iv. This is considerably less than the threshold voltage (2.5v) for leakage screening for this mechanism. Therefore, the leakage integrity performance criterion was also met for this mechanism.

The tubes with these four indications were plugged.

Page 17

A Document No.: 51-9171130-001 AREVA Sequoyah 2C17 180-Day Steam Generator Inspection Report OD Volumetric IGA at TSPs During the 2C 17 outage, four tubes were plugged due to four indications of OD volumetric IGA located within TSP intersections. Three of the four indications were less than the initial voltage screen of 0.5v.

Therefore, no additional screening was required for these indications for condition monitoring or in situ pressure testing purposes. The other indication had a voltage of 0.93v and required additional screening.

This indication was conservatively evaluated as two crack-like indications (axial and circumferential) as allowed by Reference 1. As discussed previously, Reference 1 provides a conservative screen on crack angle for circumferential flaws. Per Reference 1, if the crack angle measures <180 degrees, a proof test is not required. The crack angle for this flaw was measured as 77 degrees. Therefore, this flaw met structural integrity for the circumferential portion of the flaw. The axial extent of this flaw (0.39") is less than the throughwall structural limit of 0.44". Therefore, condition monitoring was also met for the axial portion of this flaw.

All four of the tubes with volumetric IGA at TSPs were plugged.

In Situ Pressure Testing A total of three tubes were in situ pressure tested during the 2C17 outage. As discussed above, one tube was in situ pressure tested due to an axial PWSCC indication in the u-bend that had a small risk of experiencing "pop-through" leakage. In addition to this tube, two other tubes were also in situ pressure tested due to permeability variation (PVN) signals that could not be removed with the use of magnetically biased +PointTM probe. Since these PVN signals could potentially mask a flaw and they were in locations known to be susceptible to cracking at SQN2, these tubes were also in situ pressure tested.

All three tubes were pressure tested over the full length of the tube to a minimum adjusted test pressure of 4900 psi. All three tubes passed in situ leak and proof testing with no leakage.

Tubes Pulled No tube pulls were required or performed during the 2C17 outage.

h. The Effective Plugging Percentage for All Plugging in Each SG There are no sleeves installed in the SQN2 steam generators. Therefore, the effective plugging percentage is the same as the plugging percentage as shown in Table 2-4 in Section (f) above.
