This document provides a summary of the inspection results and findings from the Salem 1R20 SG Inspection.

==2.0 INTRODUCTION==

In 1998 Salem Unit 1 commenced operating cycle 13 with the newly replaced SG from the canceled Seabrook-2 plant. Salem Unit 1 is a four (4) loop Westinghouse Pressurized Water Reactor (PWR) with Model F SGs that incorporate thermally treated Inconel 600 U-tubes. The tube bundle consists of 5,626 tubes with an outside diameter (OD) of 0.688 inches and a nominal tube wall thickness of 0.040 inches. During SG fabrication, the tubes were hydraulically expanded over the full tubesheet depth and the first ten tube rows were thermally stress relieved after U-bend formation.
The seven (7) tube support plates (TSP) are fabricated from 405 stainless steel (SS) and have broached "quatrefoil" tube holes. A flow distribution baffle (FDB) plate, also 405SS, between the secondary face of the tubesheet and the first tube support plate, provides top-of-tubesheet (TTS) sludge pile control. Tube support within the U-bend region is provided by three V-shaped chrome-plated Inconel 600 antivibration bars (AVB's). Attachment 2 provides a general summary of the Salem Unit 1 Model F SG Tube Support Arrangement and Terminology.
Consistent with Technical Specification (TS) 6.9.1.10, this report is being submitted within 180 days after the initial entry into HOT SHUTDOWN following completion of inspection performed in accordance with the Specification 6.8.4.i, "Steam Generator Program".This report includes: a. The scope of inspections performed on each SG, b. Active degradation mechanisms found, c. Nondestructive examination techniques (NDE) utilized for each degradation mechanism, d. Location, orientation (if linear), and measured sizes (if available) of service induced indications, e. Number of tubes plugged during the inspection outage for each active degradation mechanism, f. Total number and percentage of tubes plugged to date, and g. The results of condition monitoring, including the results of tube pulls and in-situ testing.Reporting requirements h, i and j are applicable for Refueling Outage 1 R20 through the subsequent operating cycles until the next scheduled SG tube inspection.

These exams differ from those exams performed for Existing or Potential Degradation in that they do not fall within the periodicity sample. Proactive inspections can provide useful information to both the utility and the industry.
They are typically performed to challenge engineering assumptions.
4.2 Tech Spec 6.9.1.10.b Active degradation mechanisms found: The active degradation mechanisms found during outage 1 R20 were AVB wear, TSP wear, and FO wear (synonymous with Loose Part Wear). A summary table of the wear indications found during the inspection outage is provided in Attachment 
: 3. A list of the AVB wear indications are provided in Attachment 7, the TSP wear indications in Attachment 8 and the FO wear indications in Attachment 9.4.3 Tech Spec 6.9.1.10.c Nondestructive examination techniques utilized for each degradation mechanism:
In accordance with Revision 7 of the EPRI PWR Steam Generator Examination Guidelines, a documented review of EPRI Qualified techniques was performed to ensure application of these techniques is pertinent to site-specific SG conditions.
Attachment 6 provides the NDE techniques utilized for each degradation mechanism.
4.4 Tech Spec 6.9.1.10.d Location, orientation (if linear), and measured sizes (if available) of service induced indications:
The only service induced indications detected during outage 1 R20 were due to AVB wear, TSP wear, and FO wear. Attachments 7, 8, and 9 provide information for the AVB, TSP, and FO wear found during 1 R20 inspection outage. The TW sizing in Attachment 7 for AVB wear and Attachment 8 for TSP wear is based on EPRI ETSS 96004.1 (bobbin coil).Four tubes had FO wear indications.
In SG 12, tube 3-3 had a possible FO wear indication reported in the freespan region above the cold leg top of tubesheet detected during the peripheral rotating coil examination.
The maximum depth was 25% TW using EPRI ETSS 27903.1. Visual inspections did not confirm a FO at this location.
It is possible that the object was removed by sludge lancing. This tube was returned to service. The surrounding tubes were rotating coil examined in the same area (Cold leg top of tubesheet) with no anomalies or degradation reported.Page 5 of 9 Attachment 1 Document Control Desk LR-N10-0365 STEAM GENERATOR TUBE INSPECTION REPORT TS 6.9.1.10* In SG13, tube 36-15, a possible FO wear indication was detected with bobbin located just below the bottom surfaces of the cold leg flow baffle. The maximum depth was determined to be 7% TW with EPRI ETSS 96004.1 (bobbin) and 15% TW with EPRI ETSS 96910.1 (+ Point). Visual inspection of the area was performed from the top surface of the baffle plate. The presence or absence of a FO could not be confirmed from the top surface. This tube was preventatively plugged and stabilized.
The surrounding tubes were rotating coil examined in the same area (cold leg flow distribution baffle) with no anomalies or degradation reported.* SG 14 had two tubes identified by eddy current with FO wear. During the bobbin coil examination, a NQI was reported 0.42 inches above the FBH in tube 34-109.Subsequent Rotating coil inspection of this location and the surrounding tubes in this region (FBH) of the tube identified three tubes with FO signals on the top of the hot leg flow baffle (Tubes 33-108, 33-109 and 34-109) with associated wear signals on two of the tubes (33-109 and 34-109). Visual inspection revealed a FO wedged between the tubes that was subsequently removed. The two tubes with wear indications were sized (+Point) with EPRI ETSS 27903.1. Tube 34-109 was plugged due to a maximum wear depth of 40%TW. Tube 33-109 was returned to service with a maximum depth of 31%TW. Tube 33-108 remained in service with no associated wear reported.4.5 Tech Spec 6.9.1.10.e Number of tubes plugged during the inspection outage for each active degradation mechanism:
Attachment 4 provides the number of tubes plugged during the inspection outage for each active degradation mechanism (and preventative plugging).
In addition to the Technical Specification criteria for plugging flaws equal to or exceeding 40% of the nominal tube wall thickness, preventative tube plugging was performed for AVB wear, data quality issues (PVN), and FO engineering analysis as described below: " AVB wear that exhibited 
>19% TW change (over previous two cycles, 1 R1 8 to 1 R20)or AVB wear with >35% TW degradation was preventatively plugged. Four tubes with AVB wear met these administrative criteria." One AVB wear location (SG1 1, tube R54-C37 at AV6) was also reported with a dent signal and therefore was depth sized with an extended +Point technique (ETSS 96910.1) at 16% TW; and subsequently the tube was plugged.* One tube in SG13 (tube R55-C82) was preventatively plugged due to data quality issues. During the 1R18 inspection outage, tube R55-C82 had a DNG call reported at 07H + 14.41". During the 1 R20 inspection outage, the bobbin coil exam reported an INR at the 07H + 14.41" location.
A sample of 1 R18 DNG indications was inspected with +Point probes during the 1 R20 inspection outage and tube R55-C82 was spun at the 07H + 14.41" location.
The +Point exam reported a NDF at the 07H+ 14.41" location.
However, a PVN was reported at 07H which was outside of the targeted area of interest (07H was examined as part of the inspection as a means for Page 6 of 9 Attachment 1 Document Control Desk LR-N1 0-0365 STEAM GENERATOR TUBE INSPECTION REPORT TS 6.9.1.10 the analyst to validate proper land marking).
PVN is a condition where the test coil impedance changes due to a change in the tubing material's inherent willingness to conduct magnetic flux lines. PVN signals are not considered to be flaws or degradation.
Rather, the signals are considered potential data quality issues that may be masking degradation.
Salem Unit 1 has not reported ODSCC at TSPs.Other plants have detected ODSCC at TSPs in thermally treated alloy 600 tubing that was detected using the bobbin probe in all cases. Nearly all of the TSP ODSCC identified to-date has occurred in tubes with higher than normal residual stress. A bobbin coil screening technique was developed to identify tubes with larger than normal residual stresses.
As part of a preventative evaluation, Salem Unit 1 conducted a residual stress screening of all SG tubes. During the evaluation, tubes with the potential for higher residual stress were identified for further evaluation.
During this evaluation, tube R55-C82 was not identified for further evaluation and was not considered to have higher residual stresses, therefore, considered to be less susceptible to ODSCC at the TSP. For tube R55-C82, the data from the Tech Spec examination (bobbin coil) at 07H was acceptable with no degradation detected.
In the cases of ODSCC at other plants, the bobbin coil inspection detected the ODSCC indication.
Bobbin is a qualified technique to detect ODSCC and since acceptable full length bobbin coil data was obtained for tube R55-C82, the PVN reported at 07H does not present a concern from a condition monitoring perspective.
However, to remove any potential that this area could result in degradation being masked during future inspections, this tube was preventatively plugged.PSEG's response to TS 6.9.1.1 0.d provides discussion of the FO wear indications and tubes plugged. In addition four (4) tubes, 20-42, 20-43, 21-41, and 21-42, in SG12 were preventatively plugged and stabilized for an irretrievable FO wedged between these tubes on the HL TTS. There was no wear detected on the preventatively plugged tubes.4.6 Tech Spec 6.9.1.10.f Total number and percentage of tubes plugged to date: During 1 R20, a total of 14 tubes were removed from service from all four-steam generators.
At the completion of 1 R20, the cumulative tube plugging in all four steam generators is 238 tubes or approximately 1.06% of the tubes removed from service. The limiting steam generator is SG 13 with approximately 1.92% of tubes removed from service. Attachment 5 provides a table of total number and percentage of tubes plugged to date.4.7 Tech Spec 6.9.1.10.g The results of condition monitoring, including the results of tube pulls and in-situ testing: A Condition Monitoring (CM) assessment was performed for the Salem Ul SGs following inspections from outage 1 R20 in accordance with NEI 97-06 and EPRI Guidelines (Including the EPRI Steam Generator Integrity Assessment Guidelines, Revision 2). Condition Page 7 of 9 Attachment 1 Document Control Desk LR-N 10-0365 STEAM GENERATOR TUBE INSPECTION REPORT TS 6.9.1.10 monitoring assessment means an evaluation of the 'as found' condition of the tubing with respect to the performance criteria for structural integrity and accident induced leakage. The'as found' condition refers to the condition of the tubing during a SG inspection outage, as determined from the inservice inspection results or by other means, prior to the plugging of the tubes. Condition Monitoring assessments shall be conducted during each outage during which the SG tubes are inspected or plugged to confirm that the performance criteria are being met.The 'as found' condition of the tubing for 1R20 is provided in response to TS 6.9.1.10.d.
The Salem Unit 1 Condition Monitoring Limit (CML) is approximately 62% TW for AVB wear, 52% TW for TSP wear, 46% TW for FO wear when using the applicable EPRI ETSS techniques, and as conservatively calculated using guidance consistent with the EPRI Steam Generator Integrity Assessment Guidelines, Revision 2. All wear measured less than the CML, analytically demonstrates that the structural integrity performance criterion is met. All wear indications detected during 1 R20 were found to be below the NDE analytical CML. The maximum %TW found during 1 R20 for AVB wear was 44% TW, for TSP wear 11% TW, and FO wear was 40% TW. Therefore, the degradation was less than the respective condition monitoring limit, demonstrating that all tubes inspected met the tube integrity performance criteria in TS 6.8.4.i.b.
During the +Point inspection of tube R55-C82 for a freespan ding in the U-bend region (DNG at 07H + 14.71") a PVN was reported at 07H. The PVN at 07H was outside the targeted area of interest of the freespan DNG at 07H + 14.71". No degradation was found at the location of interest during the +Point examination.
During the full length TS bobbin coil examination, the bobbin data for tube R55-C82 was obtained and found acceptable.
However, tube R55-C82 that was preventatively plugged due to the PVN being reported at 07H. Since acceptable full length TS bobbin coil data was obtained, this tube does not present a concern from a condition monitoring perspective No tubes required in-situ pressure testing, and no tube pulls were performed during 1 R20.4.8 Tech Spec 6.9.1.10.h The primary to secondary leakage rate observed in each SG (if it is not practical to assign the leakage to an individual SG, the entire primary to secondary leakage should be conservatively assumed to be from one SG) during the cycle preceding the inspection which is the subject of the report: PSEG did not observe any primary to secondary operational leakage at or greater than the detection threshold of approximately one (1) gallon per day over the cycle preceding the inspection in any of the steam generators at Salem Unit 1.Page 8 of 9 Attachment 1 Document Control Desk LR-N 10-0365 STEAM GENERATOR TUBE INSPECTION REPORT TS 6.9.1.10 4.9 Tech Spec 6.9.1.10.i The calculated accident induced leakage rate from the portion of the tubes below 13.1 inches from the top of the tubesheet for the most limiting accident in the most limiting SG. In addition, if the calculated accident induced leakage rate from the most limiting accident is less than 2.16 times the maximum operational primary to secondary leakage rate, the report should describe how it was determined:
PSEG did not observe any primary to secondary operational leakage at or greater than the detection threshold of approximately one (1) gallon per day over the cycle preceding the inspection in any of the steam generators at Salem Unit 1. Since PSEG did not observe any measurable SG primary to secondary operational leakage, the calculated accident induced leakage rate from the most limiting accident would not be significant.
4.10 Tech Spec 6.9.1.10.j The results of monitoring for tube axial displacement (slippage).
If slippage is discovered, the implications of the discovery and corrective action shall be provided: 100% of all in-service tubes within the tubesheet, both HL and CL, were monitored for tube axial displacement (slippage) using Bobbin coil inspections.
No indications of slippage were detected.Page 9 of 9 Attachment 2 LR-N10-0365 Salem Unit 1 Model F SG Tube Support Arrangement and Terminology Attachment 2 Document Control Desk LR-N 10-0365 SALEM UNIT 1 MODEL F SG TUBE SUPPORT ARRANGEMENT AND TERMINOLOGY AV3 ____AV4 (AVB)-,Anti-Vibration Barit Tube Support Plate (TSP)Suppo.rt -Number Top of Tubesheet (TTS)Flow Distribution Baffle Plate (FDB)FBC TSC TEC Page 1 of 1 Attachment 3 LR-N10-0365 Summary of Salem 1 R20 Wear Indications (Tubes / Indications)
