, INTRODUCTION i -
During the scheduled Sequoyah Nuclear Plant (SON) Unit 2 Cycle 8 refuefing outage (U2C8 RFO) extensive inservice inspections were conducted in all four steam generators (SGs) to address all active and potentia; damage mechanisms identified in the U2C8 Preoutage Damage Assessment. The results of the inspections were classified as follows:
SG1 392 SG3 SG4 Bobbin C-1 C-2 C-2 C-2 TTS RPC C-2 C-2 C-2 C-2 Dented TSP + Point C-1 C-1 C-1 C-1 U-Bend + Point C-3 C-3 C-3 C-3 Alternate plugging criteria (APC) was implemented during this inspection due to the detection of outside diameter stress corrosion cracking (ODSCC) at tube support plate (TSP) intersections.
A total of 3 tubes were in-situ pressure tested,1 in SG 2 and 2 in SG 4, to support leakage integrity evaluation for U-bend primary water stress corrosion cracking (PWSCC) and top of tuoesheet (TTS) PWSCC.
This report fulfills the reporting requirements of SON Technical Specification section 4.4.5.5 for reporting results of SG inservice inspection.

SG TUBE INSERVICE INSPECTION SCOPE AND RESULTS The SON SG tube Inservice inspection (ISI) initial sample and expansion for all SGs and all damage mechani:ms was as follows:
100% full-length bobbin examination in all 4 SGs for initial screening and detection of indications 100% hot leg TTS (WEXTEX transition region) examination in all 4 SGs with 0.080 mid range /0.080 high frequency / 0.115 mid range rotating pancake coil (RPC) probe.
100% Row 1 U-bend and 20% Row 2 U-Bend examinations in all 4 SGs with a magnetic biased ZETEC Row 1&2 U-Bend + Point probe.
100% >=5 volt dented hot leg TSP intersections in all 4 SGs with + Point probe.
100% < 5 volt dented TSP intersections from H01 to H03 and a 20%
random sample of H04 in all 4 SGs with + Point probe.
All test techniques were EPRI Appendix H Oualified examination techniques.
Due to the detection of axial U-Bend PWSCC in all four SGs, the U-Rend
+ Point examination was expanded to 100% of Row 2 in all four SGs.
Table 1 summarizes the SON U2C8 eddy current testing ISI exams and the results of exams conducted. Table 2 provides a summary of the tube damage detected and a characterization of the damage morphology.

Circa,cfm 'ntial P5NSCC was detected in the U-bend area of 3 tubes. The bouncirig indication, R1 C79 in SG 4, had a crack arc length by plus point of 37*,
maximum depth 100%, average depth 43.84%, and maximum voltage 2.26.
While this tube was below the Regulatory Guide 1.121 structural limit, it was in-situ tested for leakage concerns. At a test pressure of 4728 psi representing 3 detta P, no leakage was identified, i
Axial PWSCC was detected in the U-bend area of 5 tubes. None of the indications exceeded Regulatory Guide 1.121 structural length criteria. The bounding indication for leakage concerns was R1C61 SG 2. Maximum voltage by plus point for this indication was 3.21 volts with maximum depth 100% and j\ds c s\n r c\u l c 8 t p t s\b 0 d a y r p t.d o c 5

psi, and rio leakage was identified.
, Condition Monitorina for U-Bend PWSCC The limiting U-Bend PWSCC indications for condition monitoring were in-situ tested to 3 delta P and both tubes met Regulatory Guide 1,121 structural integrity and leakage integrity. Since these indications bound all U-Bend PWSCC indications, it can be concluded that all U-Bend PWSCC indications satisfy tube integrity requirements for condition monitoring.
Operational Assessment for U-Bend PWSCC The growth rate study performed during the U2C8 outage indicates that average g:owth for axial U-Bend PWSCC is 19% maximum der:h,0.06" axial length, and 21% average depth. Conservatively, with U-Bend eddy current detection capability at 40% through wall and 0.25" length, using growth rates from U2C8, and a 20% uncertainty, an indication left undetected BOC 9 would only grow to 79% maximum depth and 0.31" axial length, which does not exceed RG 1.121 length and aepth criteria of 0.71" for 100% through wall.
The growth rate study performed during the U2C8 outage indicates that average growth for circumferential U-Bend PWSCC is 47% maximum depth,43*
circumferential extent, and 29% average depth. Using the smallest detected circumferential indication from U2C8 as detection capability (36 ), an indication left undetected BOC-9 would only grow to 79", which would not be a leckage or structural concern.
The U-Bend inspection at EOC-8 was more extensive in scope than the EOC-7 inspection, which did not include 100% of Row 1 and 2 U-Bends in all 4 SGs.
Given the 100% inspection with improved + Point detection at EOC-8, the potentially undetected indications left in service for Cycle 9 can be expected to <
be smaller than that for Cycle 8. Since operating conditions are essentially the same between Cycles 8 and 9 and all EOC-8 indications satisfied tube integrity requirements, it can be expected that all U-Bend indications found at EOC-9 will also satisfy Regulatory Guide 1.121 guidelines.
PWSCC TTS A total of 35 tubes was predicted to be plugged for PWSCC at TTS based on SON and industry experience, Actual results of 10 tubes plugged show a decrease in PWSCC at TTS, which is attributed to shotpeening at the cycle 5 refueling outage. The majority of these indications are in the central region of the tube bundle as predicted for WEXTEX cracking.

A total of 3 indications were identified as circumferential P_WSCC at TTS Only
- one circumferential indication was in the transition The other two were below -
4 the top of the tubesheet by at least 1.69", The indication in the transition was
- R12C57 SG 2 at HTS .08. The voltage was 0.52 by + Point, which was well below screening criteria of 1.5 volts for leakage. The maximum depth was only 76% with an average depF of 45.91%. None of the circumferencial PWSCC at TTS caused leakage or structural concern.
, None of these indications were stabilized based on screening critc 'a specifically calculated for SON and WEXTEX expansion transitions. All three tubos are in Zone 3 or 4 and are well below 120 . Since the damage mechanism is ID l initiated and the tubes are taken out of service, these small indications will not
_ grow.
A total of 7 indications were identified as axial PWSCC at TTS. All were less
. - than 0.47" long by + Point and all but one indication were inside the tubesheet.
The indication which was in the tubesheet transition exceeded the 2 volt criteria for leakage concerns (R7C17 SG 4). This indication had a 100% maximum
- depth,0.32" axial length,56.53% average depth, and 3.55 maximum voltage.
[ This was clearly the bounding indication and was in-situ tested to 3 delta P.
5 The tube raet structural integrity and no leakage was identified.
Condition Monitorina for TTS lNSCC
! The limiting axial TTS PWSCC indication (R1C17 SG 4) for condition monitoring
, was in-situ tested to 3 delta P and met Regulatory Guide 1.121 structural i integrity and leakage integrity. Since this indications bound all TTS axial PWSCC indications and no circumferencial TTS PWSCC caused leakage or 4 structural concern, it can be concluded that all axial PWSCC indications satisfy tube integrity requirements for condition monitoring.
Operational Assessment for TTS PWSCC
- The growth rate study performed during the U2C8 outage indicates that average
, growth for axial PWSCC at TTS is 21% maximum depth, 0.05" axial length,12%
[
average depth. Conservatively, if eddy current detection capability is 40%
through wall and 0.25" length, using growth rates from U2C8, and a 20%
uncertainty, an indication left undetected BOC-9 would only grow to 81%
e maximum depth and 0.3" axial length, which does not exceed RG 1.121 length
- and depth criteria of 0.47" for 100% through wall.
The growth rate study performed during the U2C8 outage indicates that average growth for circumferential PWSCC at TTS is 38% maximum depth,26'
- circumferential extent,23% average depth. Using the smaltest detected circumferential indication from U2C8 as detection capability (36'), an indication 4

I;ft und;t:ct;d BOC-9 would only grow to 62*, which would not be a leakage or structural concern.
Given the 100% TTS + Point inspection at EOC-8, the potential undetected indications left in service for Cycle 9 can be expected to be smaller than that for Cycle 8. Since operating conditions are essentially the same between Cycles 8 and 9 and all EOC-8 indications satisfied tube integrity requirements, it can be l expected that all TTS indications found at EOC-9 will also satisfy Regulatory j Guide 1.121 guidelines.
ODSCC TSP A total of 480 axial ODSCC indications was detected in 447 tubes at non-dented intersections during the Unit 2 Cycle 8 outage. APC implementation continued i in non-dented tubes and 478 indications were left in service based on application of APC. This number was less than predicted due to the effectiveness of pressure pulse chemical cleaning and secondary system chemistry. A detailed report containing the 90 day reporting criteria for APC is Attachment 1.
No ODSCC was detected at the top cf the tubesheet.
N_gn Structurally Sionificant Damaae Mechanisms Detected AVB Wear A total of 5 pluggable tubes were predicted for AVB wear. A total of 94 indications in 47 tubes was detected with only one tube p ugged; SG 2 R29 C42 at AV3 .03 with a 43% through wall indication.
Cold Lea Wastaae A total of 5 tubes was predicted to be plugged for cold leg wastage. A total of 52 indications in 51 tubes was detected with 4 tubes plugged:

Loose Parts Damaae Foreign object search and retrieval was performed on all SGs and all but one identified foreign objects were retrieved. The object appears to be a nail on the hot leg, secondary side of SG 2 between Row 33 and 34 with the flat head j\d oc s\n rc\u i c 8 tpt s\90 d a yrpt.d o c 8 1

l'etwssn Columns 37 and 38 and the tip in about Column 40. It appeared to be approximately 1/8" in diameter and 3 % inches long. The tubes surrounding the .,
object were tested with plus point and bobbin coil. No tube wear was identified.
A safety evaluation was performed for Cycle 9 operation with the object remaining in place (Attachment 2).
All potential loose parts identified with eddy current were reviewed and no other loose parts were ' A atified. No tubes were plugged for potential loose parts or loose parts damage.
Cracked Sucoort Plate Indications Cracked tube support plate indications (CSPs) are indications of cracks in the tube support plate and not necessarily indicative of tube degradation. A total of
- 12 CSPs were reported. There were 3 in SG 1,4 in SG 2,2 in SG 3 and 3_in SG
- 4. These were detected during an automated analysis of bobbin data and have been tracked at SON since 1900 and will continue to be tracked. No tube repair action ms required.
SON unit 2 steam generators do not have extensive support plate cracking.
Therefore, design basis function of the support plate has not been lost. There is also no evidence of wrapper drop or wrapper degradation.

l l 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(9)(d).
Based on the criteria of 10 CFR 50.59 and utilizing the criteria of Regulatory Guide 1,121, TVA concludes that the integrity of the Sequoyah Nuclear Plant Unit 2 SGs was maintained during Cycle 8 and will be maintained through full cycle 9, and does not represent an unreviewed safety question.
