.' I INTRODUCTION During the scheduled Sequoyah Nuclear Plant (SON) Unit 2 Cycle 9 refueling outage (U2C9 RFO) extensive inservice inspections were conducted in all four steam generators (SGs) to address all active and potential damage mechanisms identified in the Unit 2 Degradation Assessment. The results of the inspections were classified as follows:
SG1 SG2 SG3 SG4 Full Length Bobbin Coil C-2 C-2 C-2 C-2 U-Bend + Point C-2 C-3 C-1 C-1 TTS RPC C-2 C-2 C-2 C-2 Dented Plus Point C-1 C-1 C-1 C-1 Freespan Ding + Point C-1 C-1 C-1 C-1 ARC implementation continued during this inspection due to the detection of '
outside diameter stress corrosion cracking (ODSCC) at tube support plate (TSP) intersections. A report with details of this implementation is enclosed as an Attachment.
This report fulfills the reporting requirements of_ SON Technical Specification section 4.4.5.5.b for reporti ig results of SG inservice inspection, section 4.4.5.5.c for C-3 reporting, and the Generic Letter 95-05 required 90-day report I for voltage-based repair criteria.

.y SG TUBE INSERVICE INSPECTION SCOPE The SON SG tube inservice inspection (ISI) initial sample and expansion for all SGs and all damage mechanisms was as follows:
100% full-length bobbin examination in all 4 SGs Following the Unit 2 Cycle 9 outage, during review of data, it was L discovered that the bobbin coil data for one tube, SG3 R7 C14, was l missing one support plate signal. The partial tube test occurred when an L operator inadvertently. stopped and restarted the eddy current tester while the probe continued to be pulled from the tube. The section of tube not -
recorded was the 4* hot leg support plate and a portion of the freespan
, tubing between the 3'd and 5* hot leg supports. One analyst identified the l problem, and recorded it as "RBD," retest bad data. The resolution analyst changed the call to "NDD," no degradation detected. The
- resolution analyst failed to notice the unusual event of a missing support.
L l The problem was entered into the Sequoyah Corrective Actions Program l
and the following corrective actions were completed:
- 1. Steam generator 3 data was reviewed for other retests identified by l either the primary or secondary analysts which were not kept as retests by the resolution analysts.
- 2. Twenty percent of the other steam generators' data was reviewed for L retests identified by primary or secondary analysts and not kept as retests by the resolution analysts.
- 3. Westinghouse was notified and instructed to alert acquisition operators and analysts of the potential for this problem.
l
- 4. SG3 R7 C14 data from the previous outage, Cycle 8, was reviewed to l
ensure no indication of degradation exists which could affect the I operability of the plant.
l l 5. The potential for this problem will be raised in future training of analysts.
1 Upon review of the 20% of the other steam generators, one additional L tube, SG2 R27 C57 was found to be missing the 1*' hot let support plate and a portion of tubing between the top of the tubesheet and the 2"'
l support plate.
Ilsglsqntu2ct/u2c8 nrc report 4 E
y After this finding, the remaining 80% of all steam generators' retest data was reviewed. No additional tubes were identified with missing portions of data. SG2 R27 C57 data from the previous outage, Cycle 8, was reviewed to ensure no indication of degradation exists which could affect the operability of the plant.
100% hot leg top of tubesheet (TTS) (WEXTEX transition region) examination in all 4 SGs with plus point probe.
100% Row 1 and 2 U-Bend examinations in all 4 SGs with magnetic biased ZETEC plus point Row 1&2 U-Bend RPC probe.
100% hot leg freespan dents from the top of the tubesheet to H02 with plus point probe.
100% >=5 volt dented TSP intersections from H01 to H07 in all 4 SGs with plus point probe.
100% < 5 volt dented TSP intersections from H01 to H03 and a 20% random sample of H04 in all 4 SGs with plus point probe.
100% of <2 volt dented TSP intersections were examined during the bobbin coil examination utilizing the qualified technique for detection of primary water stress corrosion cracking (PWSCC). This requires an additional two days of extensive analyst training and testing.
The inspection of dented TSPs is performed to envelop the highest TSP with identified PWSCC indications based on unit 1. experience since the PWSCC degradation mechanism is strongly temperature dependent.
All test techniques used for detection were EPRI Appendix H qualified examination techniques and validated for use at SON. Sizing techniques )
were also Appendix H qualified where available. If qualified sizing techniques did not exist, the best available technique was used.
No expansions were necessary, ling /sqntu2ctlu2c8 nrc report 5 ,

INTEGRITY ASSESSMENT CRITERIA All crack-like indications were screened for in-situ pressure testing using I~
guidance from the Draft EPRI in-Situ Guidelines and using critical flaw
, parameters developed specifically for Sequoyah by Westinghouse. Both L documents support a three-step process for screening for structural and for leakage integrity, beginning with . length for structural integrity and voltage for leakage integrity.
The screening values for 3 times normal operating delta pressure are as follows.
Uncertainties are accounted for in the screening criteria where applicable:

PWSCC U-Bend i l
A low occurrence of PWSCC in the Row 1 U-bend area was predicted in the {
degradation assessment. Axial PWSCC was detected in 4 tubes. J l
C-3 Reportina Reauirement i
SG 2 had three tubes with U-Bend PWSCC. Since the inspection scope for Row j 1 and 2 U-Bends in SG 2 was only 157 tubes, this inspection was categorized j as C-3. However, since 100% inspection of Rows 1 and 2 was performed and J since all indications were in Row 1 tubes, no further investigation was necessary. PWSCC at inner radius U-Bends is directly related to cold work and residual stresses associated with the tubing manufacturing technique. The Unit 2 U-Bends operated in this condition for multiple cycles and subsequently were in situ stress relieved as a corrective measure. Cracking initiated prior to stress relief and continues to grow to detectable levels. Also, continually improving i detection techniques are being utilized. The U-Bends were inspected with I magnetic bias plus point for the first time this inspection. The 100% inspection {
ensures that significant flaws are removed from service.

Operational Assessment for U-Bend PWSCC For axial U-Bend PWSCC, using the worst growth from the last three outages at Sequoyah determined by the largest growth minus the smallest detected flaw, the largest growth in length is 0.33". Using the smallest indication detected in the EOC-9 inspection,0.16", the worst SON growth rate,0.33", and the sizing uncertainty from ETSS 96703,0.13", an indication left undetected BOC-10 would grow to 0.62" axial length, which is less than the 0.714" structural length criteria.
Assuming the undetected crack grew to 100% this indication would not challenge structural integrity. The largest voltage growth was 2.04 volts. With detection capabilities as low as 0.57 volts EOC-9, a missed indication could grow to 2.61 volts. Assuming the undetected crack grew to 100%, this indication would be bound by prior in situ testing and would not compromis6 'eakage integrity. Typical PWSCC indications at U-Bends at SQN are short (iess than 0.5") with one point at maximum depth. Typical average depths are less than 60% and voltagn are less than 2 volis.
The U-Bend inspection at EOC-9 included 100% of Row 1 and 2 U-Bends with a magnetic bias plus point probe. Given the 100% RPC inspection at EOC-9, the potential undetected indications left in service for Cycle 10 can be expected to be equal to or smaller than that for Cycle 9. Since operating conditions are essentially the same between Cycles 9 and 10 and all EOC-9 indications satisfied tube integrity requirements, it can be expected that all U-Bend indications found at EOC-10 will also satisfy performance criteria. I PWSCC TTS l
Twenty-six tubes were predicted to be plugged for PWSCC at TTS based on SON and industry experience. Sixteen PWSCC indications were identified during this inspection. Ten were identified during the U2C8 inspection. These indications are primarily in the central region of the tube bundle as predicted for WEXTEX c,acking.

, 223 structural screening criteria. The largest maximum voltage was 0.9 volts, which is below the 1.5 volt leakage screening criteria. Therefore, no TTS PWSCC circumferential indications challenge structural or leakage integrity. All s circumferential cracks were compared to stabilization criteria, and none exceeded the criteria; therefore, no tubes were stabilized.
' A total of 13 indications were identified as axial PWSCC at TTS. The largest and bounding indication was 0.29", which is below the freespan structural screening criteria. No axial indication exceeded the 2 volt screening criteria for leakage integrity. The largest voltage indication was 1.22 volts.
Condition Monitorina for TTS PWSCC All TTS PWSCC indications were below screening criteria; therefore, all indications met structural and leakage performance criteria for EOC-9.
Operational Assessment for TTS PWSCC The growth rate study performed during the past three SQN outages indicates that the worst growth for axial PWSCC at TTS is 0.17". Using the smallest
. indication detected EOC-9 inspection (0.06") and the sizing uncertainty from ETSS 96703 of 0.13", an indication left undetected 80C-10 would only grow to 0.36". Assuming the indication grew to 100% maximum depth, this indication 4 would still not challenge structural integrity. The worst maximum voltage growth from SQN growth data is 0.89 volts. Using the smallest voltage indication detected EOC-9 (0.4) as the detection threshhold, an indication would grow to j 1.29 volts, which would not challenge leakage integrity even if the indication was l 100% through wall. ,
The growth rate study performed during the past three SQN outages indicates '
that worst growth for circumferential PWSCC at TTS is 13 . Using the smallest detected circumferential indication from U1C9 as detection capability (25 ) and the sizing uncertainty from ETSS 96702 (21.02 ), an indication left undetected BOC-10 would only grow to 59 . Assuming the indication grew to 100% through 1/sglsqnlu2c9/u2cs nre report 10 l
wall, this indication would still not challenge structural integrity. The worst maximum voltage growth from SQN growth data is 0.61 volts. Using the smallest voltage indication detected EOC-9 (0.2 volts) es the detection threshold, an indication left undetected BOC-10 would grow to 0.81 volts, which would not challenge leakage integrity'and would be consistent with EOC-9 data. '
The PWSCC TTS indications from EOC-9 inspection met tube integrity requirements for condition monitoring, and since operation cycle and conditions will be essentially the same for Cycle 10 and given the 100% inspection, it is L
again expected that any axial PWSCC TTS indication identified EOC-10 will L rheet tube integrity requirements.
ODSCC TSP A total of 659 axial ODSCC indications were detected in non-dented intersections during the Unit 2 Cycle 9 outage. Generic Letter 95-05 ARC implementation continued in non-dented tubes and a detailed report is included as Attachment 1.
AVB Wear Based on past indications and growth rate data from past outages, three tubes were predicted to be plugged for AVB wear. A total of 97 indications were detected with only two tubes plugged; SG1 R33 C59 with a 40% through wall indication at AV3+.00 and SG1 R34 C53 with a 40% through wall indication at AV2+.00 Cold Lea Wastaae Three tubes were predicted to be plugged for cold leg wastage. A total of 94 indications were detected with 9 indications exceeding the plugging limit of 40%
through wall and plugged.

1 SECONDARY SIDE INSPECTION SCOPE AND RESULTS Cracked Support Plate Indications Cracked tube support plate indications (CSis) are indications of cracks in the tube support plates and not necessarily indicative of tube degradation. These indications are detected during automated analysis of bobbin coil data. They are traced back to history and all have been tested with rotating coil to ensure that no active damage mechanism exists.
SON unit 2 steam generators do not have extensive support plate cracking.
Therefore, design basis function of the support plate tias not been lost. There is also no evidence of wrapper drop or wrapper degradation.
Upper Internals inspection An upper internals inspection was performed on two steam generators and no degradation was detected.
Sludae Lancina Sludge lancing was performed on all four steam generators: 34 pounds of sludge was removed from SG1,44 pounds frorn SG2,57.5 pounds from SG3, '
and 39 pounds from SG4. A post-lance inspection confirmed that the top of the tubesheet on all generators was clean.
Foreian Obiect Search and Retrieval (FOSAR)
Foreign object search and retrieval was completed on all four steam generators and all identified foreign objects were retrieved.

CONCLUSIONS The NDE testing completed on the SON Unit 2 SGs and plugging of defective tubes met the Technical Specification and ASME Section XI code requirements I
for Inservice inspection; therefore, each SG has been demonstrated operable.
Alternate Plugging Criteria was implemented in accordance with the Unit 2 Technical Specification License Condition 2.C(8)(b). j i
i Based on the criteria of 10 CFR 50.59 and utilizing the criteria of Draft l Regulatory Guide 1.121, TVA concludes that the integrity of the Sequoyah Nuclear Plant Unit 1 steam generato s was maintained during Cycle 9 and will be maintained through full cycle 10, and does not represent an unreviewed safety l question.
