1. INTRODUCTION On October 9, 2001, TMI-1 was shut down for Refueling Outage 1R14. During this refueling outage, TMI-1 performed Eddy Current (ECT) examinations of the Once Through Steam Generators (OTSGs). The scope of the examinations includdtubig,,l.S d plug.Te exam-inations were required b) 141- ......... Spcciiaton

.. . fence 1). Technical Specification License Amendment #237 (Reference 2), and TMI-1 engineering requirements.

During Outage lRl4 all. in-service tubes were cxamined with a bobbin coil probe and approximately 39% of the upper tubesheet kinetic expansions were examined with a rotating probe. In OTSG-A, eddy current examinations were performed on 14,195 in-service tubes, 82 sleeves, and 157 installed plugs. In OTSG-B, eddy current examinations were performed on 15,127 in-service tubes, on 85 sleeves, and 88 installed plugs. The examinations determined that previously plugged tube B66-130 became severed and impacted adjacent tubes. This finding was the subject of Licensee Event Report (LER) Number 2001-003-00 (Reference 14) and NRC Information Notice 2002-02 (Reference 24). As part of the investigation and corrective actions for this finding 647 previously plugged tubes were examined in OTSG-A, and 223 previously plugged tubes were examined in OTSG-B.

IL METHODS A. DATA ACQUISITION The Eddy Current (ECT) Examinations were performed using the Zetec Miz-30 Digital Multi-Frequency Eddy Current System with Eddynet 98 Software. The data was directly recorded to hard disks located on site and then spooled to the remote analysis locations for primary and secondary analysis. The ECT raw data and analysis results were then transferred to optical disks for site storage.

Data acquisition was performed remotely using the Framatome "ROGER:' in head manipulators and Zetec Model 1OD probe pushers. Dual guide tubes were used to the extent practical. Examinations were performed at all four heads in order to support the required examination schedule.

The ECT examinations were performed using a variety of techniques and probes that were tailored to address the specific areas of interest being examined. The teclmiques used for exanmination were based on industry qualified techniques which were site qualified or were plant specific qualified techniques (where industry qualified techniques did not exist or were not applicable). The active and potential damage mechanisms were documented in the "TMI-1 Outage 1R14 Degradation Assessment & Condition Monitoring Checklist, Revision 0". Memorandum TMI-NOB-3, 5973-2001-009 (Reference 16). Table ri-1 provides a listing of the specific Appendix H qualification applicable for each damage mechanism. Framatome Technologies report 51 5005406-01, "Qualified ET Exam Techniques for Three Mile Island 1R14" (Reference 17) provides further details on site applicability for each examination technique. The examinations were performed under TMI-1 Surveillance Procedure 1300-4B (Reference 4) and Framatome Techmologies Procedure 54-ISI-400-11 (Reference 5) and are further discussed in the following sections.

1. The EPRI Appendix H bobbin technique is qualified for depth sizing; however, that method is not presently used in OTSG's. TSP wear depth sizing is based on rotating probe data or on the bobbin coil probe data.

Reference 20 provides guidance for each technique when to be used for determining depth measurement. See Reference 21 for additional information on bobbin coil examination for TSP wear.

2. This technique is qualified for sizing by length or depth percent through-wall of circumferential PWSCC at expansion transitions.
3. This technique is qualified for sizing by length or depth percent through-wall of axial PWSCC at dents.
4. This document provides the results of studies performed for TMI-1 to determine the expected depth and length sizing errors expected for various rotating coil eddy current probe examination teclmiques. As a result of this study. TMI has chosen to use the mid-frequency plus point coil for depth sizing ID IGA/SCC and length sizing crack-like indications. The 0.080" high frequency pancake coil was chosen to provide axial and circumferential length dimension for ID IGA volumetric indications. Based on this report., TMVII has chosen to assign a potential 32.6% TW undermeasurement to percent through-wall measurements made on ID indications with the plus point coil in the kinetically expanded region (an indication measured as >67% TW is considered 100% TW for flaw leakage evaluation). The study also concluded that axial and circumferential length measurements are expected to be conservative (i.e.., measured length is greater than actual flaw length) for both crack-like and ID volumetric indications. Pulled tube exams for the 12R outage confirmed that length measurements are conservative for the ID volumetric indications.
5. This examination technique has been retired by EPRI. It is used for exaunination of the active explosive plugs (85 total remaining at TMI-1). The qualification for this technique is considered valid because the qualification was simply retired by EPRI because of perceived lack of industry use and not because of poor flaw detection capabilirv.

TR-15 1, Revision 0 A. I Tube Bobbin Coil Examinations The general examination of tubing material was performed from the inside diameter of the tube using a bobbin coil probe. This probe is the most durable and efficient probe available and, when used with tie proper ECT instnrwentation. allows en.as--At a,--t,, v- s inhexcess o401 speeeds ahsprecn.E I 4 inches minations were performed per second. Exarru with a probe speed that did not exceed 40", per second. The data from this probe was used to detect tube wall degradation from such mechanisms as Intergranular Attack (IGA), Intergranular Stress Corrosion Cracking (IGSCC) tube-wto-tube support plate wear, and impingent. The data acquired was also used to assure all tube support plates were present at their expected locations. All bobbin coil examinations were full length unless otherwise noted. For the purpose of this report, a full-length bobbin coil examination is from the kinetic expansion transition in the upper tubesheet to the roll expansion transition in the lower tubesheet. The 0.540" diameter probe was used to examine tubes with previously identified bobbin coil ID indications while the 0.510" probe was used for initial examination of all other tubes. A 0.480" diameter bobbin coil probe was used to examine the region of three tubes that would not pass a 0.5 10" diameter bobbin coil probe.

Tubes with indications of suspected degradation found during the bobbin coil examinations were re-examined using an MRPC probe.

A.2 Sleeve Bobbin Coil Examinations The unexpanded sections of sleeves were examined with a .400" bobbin coil probe to detect degradation mechanisms such as OD IGA, OD IGSCC, or tube-to-tube support plate wear. This probe was used for these examinations because of its durability and higher examination speed. The examinations were performed at a speed less than 12" per second because of the probe's tight fit in the sleeves.

A.3 Motorized Rotating Pancake Coil (MNRPC) Tube Examinations IMRPC examinations of tubes were performed as diagnostic examinations following bobbin coil examinations or for detection of specific degradation in areas where higher sensitivity and additional information were desired (e.g. kinetic expansions, lower tubesheet crevice, dented regions, and shop re-rolled tubes). The MRPC probe examinations were typically limited to specific lengths of tubes.

A.4 Plus Point Examination of Sleeves All of the TMI-l sleeves are 80" long Inconel 690 sleeves that are installed at the upper end of the parent tube.

The expansions (including expansion transitions) of sleeves were examined using a Plus Point rotating probe.

The examinations were generally performed from approximately 3 inches below the lower sleeve end to the 15th tube support plate (which includes the two lower expansions) and an area in the upper tubesheet which included the upper expansion. This techmique is required for examination of the parent tube below the lower sleeve end, the lower sleeve end, and roll expansion regions only: however, all acquired data was evaluated by the data analysts. See Figure II-1 for TMI-I's sleeve configuration.

A.5 B&W Rolled Plug ECT Examinations B&W rolled plugs were examined using a rotating pancake coil probe. The examinations were performed on the "'push" or the "pull" and data was recorded as the probe was being inserted or retracted at 0.1 inches per second. The examinations were performed primarily to detect primary water stress corrosion cracking (PWSCC) in the roll transition regions. This cracking has typically been identified as axially oriented in the toe region, and circunmferentially-oriented or axially-oriented in the heel region.

TR-151, Revision 0 A.6 Explosively Welded Plug ECT Examinations B&W explosively welded plugs were also examined using an MIRPC probe. The examinations were performed on the "push" or the "pull" and data was recorded as the probe was being inserted or retracted at 0.1 inches per second. These examinations were performed primarily to detect PWSCC in the expanded regions and tapered portion of the p hased on at oher '

The examinations were performed on the "push" or the "pull" and data was recorded as the probe was being inserted or retracted at 0.1 inches per second. The examinations were performed primarily to detect PWSCC in the roll transition regions.

B. DATA ANALYSIS PROCESS Eddy current data analysis was performed using Exelon Procedure ER-AP-33 5-040, Revision 0 (Reference 8) and Exelon T&RM ER-TM-335-1005, Revision 0 (Reference 20). These documents are based on the recommendations of the EPRI PWR Steam Generator Inspection Guidelines (Reference 9) and also meet the requirements of the TMI-1 Technical Specifications (Reference 1) and the ASME Boiler and Pressure Vessel Code (Reference 10).

B. I Data Analyst Qualifications The data analysis process was performed by Framatome ANP (FRA-ANP) and Duke Engineering and Services (DE & S) using personnel quahfied and certified to at least Level IIA in accordance with the employers' approved QAlTraming programs. In addition, these personnel were recognized as Qualified Data Analysts (QDA) as defined in the EPRI PWR Steam Generator Inspection Guidelines, Appendix G. As a supplement to these qualifications, all data analyst personnel received site-specific indoctrination and training. The program included both classroom lectures and "hands on" practice, using eddy current data and experience from TMI and other B&W-designed plants. The training covered generic OTSG degradation mechanisms and examination methods, and specifically addressed the bobbin coil and rotating probe methods used at TMI.

The total site-specific indoctrination/exanmination process encompassed approximately 36 working hours per analyst and was conducted by a TMI-1 Authorized Level III Analyst. At the completion of the indoctrination each data analyst was required to pass a performance demonstration prior to analyzing bobbin coil or rotating probe data for detection of flaws. The test was generated by the EPRI Site Specific Performance Demonstration (SSPD) program or, for methods that are not supported by the EPRI SSPD program, a pre designed test.

B.2 Data Analysis Sequence The data analysis process was perfonned in accordance with the same procedures referenced in the above section on data analyst indoctrination and training. The process was performed in four (4) steps with at least two (2) separate data analysts evaluating the data from each examination. The data analysis process included:

1. Primary Analysis: The primary analysis included an evaluation of the ECT data and the recording of attributes identified in Appendix I over the full length of the exam. As stated previously, for bobbin coil examination of tubes. full length is the unexpanded portion of tube from the lower tubesheet roll expansion transition to the upper tubesheet kinetic expansion transition. For MiRPC examinations of the upper tubesheet expansion transitions and kinetic expansions. full length included the examined region of unexpanded tubing, the expansion transition, and a pre-defined length of expanded tube above the transition. The pre-defined length was displayed to the analyst and was based on required expansion leng-th as defined in the plant's kinetic expansion acceptance criteria. If indications were recorded in the transition or expanded region of the kinetic expansions, an additional 2.0" of expanded 9

TR-151, Revision 0 region was evaluated. Some tubes required evaluation beyond the minimum required length plus 2.0" to determine the acceptabilit, of the expansion for continued service. In these cases the analyst recorded the actual expanded region examination length as part of the reported results.

2. Secondary Analysis: This analysis was performed in the same manner as the primary analysis described above. The secondary analysis was performed by a different QDA than the QDA that performed the primary analysis.
3. Resolution Analysis: The results of both the primary and secondary analyses were reviewed by designated resolution analyst(s). This review combined the primary and secondary analyses results, resolved any discrepancies, and assigned final dimensions to any indications requiting length. width, and/or depth sizing. For this outage personnel qualified to Level III QDA performed this function. In the case of indications which were initially reported as exceeding the repair criteria by any analyst, but resolved as not requiring repair, a Level III QDA from both FRA-ANP and DE & S were required to concur that the indication did not exceed the repair criteria.
4. Designated ODA: A designated QDA reviewed the resolution analysis results. This review included reviewing all repairable indications overruled by resolution analysis, reviewing a sample of indications recorded during the analysis process, and reviewing indications as requested for reconsideration (by any primary or secondary analyst who may have disagreed with, or questioned, a resolution analysis evaluation).

B.3 Data Analysis Software The data for examinations was evaluated using Zetec Eddynet 98 Analysis software, Version 2.20.

B.4 Recording of Indications Eddy current indications were recorded to permit dispositioning the examination results and to facilitate monitoring the tubes during future examinations. The recorded indications fall into two basic groups, "indications from Tube Wall Degradation" (e.g., indications assigned a "VOL" code or "I" code); and "indications from Possible Damage Precursors" (e.g., indications assigned other three letter codes such as "DNT"). The specific criteria used to record the indications were dependent upon the type of probe being used. A complete list of abbreviations and definitions used to classify, indications is included as Appendix I to this report.

Indications from Tube Wall Degradation Generally indications of tube wall degradation were initially recorded during the primary and secondary analysis of the bobbin coil data. Some indications were assigned a "percent through wall" value based on the phase angle of the indications (if they were ID-initiated by bobbin coil examination) or based on flaw amplitude (ifthey were unchanged and previously dispositioned as tube-to-tube support plate wear that had not changed). When the indication could not be accurately assigned a through wall value using bobbin coil examination data, it was assigned a three letter code such as BVC, ADI. or NQI to indicate the presence of a possible flaw. In these cases. the indication's location- amplitude, signal phase angle and three-letter code were recorded to permit further evaluation of the tube.

Once the initial screening of bobbin coil indications was completed, supplemental examninations wxere performed using rotating coil probes (generally 3-coil MNRPC with +Point coil. 0. 115" pancake coil. and 0.080"'

10

TR- 151, Revision 0 shielded high frequency pancake coil). The data from the rotating probe examinations was analyzed and indications were recorded using three letter codes to indicate the morphology of degradation and." in some cases, a percent through wall was assigned. hi general, indications were recorded as SAL, MAI, SCI, MCI, SVI, MVI, or VOL. These codes indicate whether the indication is single (S) or multiple (M), circumferential (C) or axial (A). and whether or not a volumetric (V) condition is present. The "VOL" code signified that -an

. ya....

v insiucdujarieteu.....

-:*n . ... the bobb ii..... ii.- lcatiu nature. Like. U U-were recorded along with the location, amplitude, and phase angle of the signal. Additional line entries were also included for some MRPC indications to record indication circumnferential extent and axial extent.

An exception to the above procedure occurred when an MRPC examination was pre-scheduled for a specific region such as the kinetic expansion region. In this case only the MRPC data was used for dispositioning the tube. (The bobbin coil is not used in the expanded region.) The actual analysis process was performed in the same manner as described above.

Indications from Possible Damage Precursors The analysis of eddy current data may also identify indications that are not specifically attributed to tube wall degradation. These indications may be the result of irregularities in the tube wall profile (IDC), changes in the magnetic permeability (PVN), denting (DNT), or other changes in the electrical impedance of the tube not related to tube wall degradation. All recorded bobbin coil probe "IDC" and "PVN" indications were examined with an MRPC probe.

Approximately 33% of the dent indications located above the lower tubesheet, 100% of the upper tubesheet secondary face dents, and dents >16 volts by bobbin coil probe at the lower tubesheet secondary face or below and not inside the defined kidney region, were examined with an MRPC probe. Dents inside the lower tubesheet defined kidney region were examined with an MRPC probe as part of the kidney region exanmination sample.

Indication Locations The locations of the ECT indications were recorded to identify their "elevation" or "axial location" in the OTSG tubes. For free span indications, the locations were generally recorded in inches above "+" the tubesheet surfaces or tube support plate centers. For indications located within or adjacent to the tube support plates, the indications are recorded as "+" or "-" from the tube support plate center. The relative location of the tubesheets and tube support plates is shown in Figure 11-2.

B.5 Data Management Two separate data management systems were used to assure indications were documented and dispositioned appropriately. The examination results were obtained from the Eddynet report files and loaded into the data management systems used during the outage. The FTI FDMS and Zetec Data Management Systems were used independently to track eddy current examination results. Final results reports from the two systems were then compared to address any, inconsistencies between the two systems. The overall generator examination was considered completed when both systems produced the same results and indicated that the required examinations were complete. After completion of the lR14 Outage the FDMS System results were used to load data into the TMI-I data management system.

C. DISPOSITION OF RESULTS C. I Inside Diameter IGA Inside diameter (ID) IGA eddy current indications in unexpanded tubing were dispositioned in accordance with the TMI-1 Tectmical Specifications (License Amendment No. 237). In accordance with the amendment. all ID IGA indications that were detected during the bobbin coil eddy current examinations were subsequently 11

TR-151, Revision 0 examined with MRPC probes. The length and width of the indications (as discerned by MRPC extent calls) were compared to the repair limits stipulated in the Technical Specification. In addition, the MIPRPC examinations were used to conlirm that the indications were volumetric in morphology (in order to prevent crack-like indications from remaining in service.) The surface of origin (i.e. inside surface) was also confirmed for all ID IGA indications. ID IGA indications with sufficient bobbin coil signal-to-noise ratio and bobbin, were also g-.en a per.cent "u-... . e I U"- on W-'"V uidniaete bobbia

In addition, the remaining ID IGA indications were verified for serviceability by in-situ pressure testing selected tubes [See Sections II.D and III.C of this report] and a growth evaluation, in accordance with the Technical Specification. [See Section III.B. 1]

Appendix HIprovides a list of tubes, sleeves, and plugs containing indications as a result of eddy current examinations. The 3-letter code "VOL" was used to delineate ID IGA indications in tubing. [Note that some of the indications listed in the Appendix were removed from service as a result of the tube plugging. The data for tubes plugged due to eddy current indications has been identified by use of bold print.] At the end of the 1R14 Outage 992 recorded IMIGA indications in 554 OTSG "A" tubes, and 49 recorded ID IGA indications in 33 OTSG "B" tubes, remain in service in the TMI-1 generators. These indications are located below the kinetically expanded region (below ETL+0.0 inches). The ETL (Expansion Transition Location) is the location in the upper tubesheet where the tube changes in diameter from fully expanded tubing to the expansion transition).

C.2 Kinetic Expansion Region TMI-I 's OTSG tubes have 17" or 22" long kinetic expansions within the generators' upper tubesheets. During the 1R14 Outage, approximately 38.9% of the unsleeved/unplugged tubes with 17" kinetic expansions and approximately 20.4% of the unsleeved/unplugged tubes with 22" kinetic expansions were inspected with a rotating probe (i.e. MIRPC). The Outage 1R14 samples included all tubes identified as "Potential Leakage Contributors" during Outage 13R.

Analysis Process Each tube examined with the rotating probe in the kinetic expansion region was analyzed to determine if the tube was a structural and/or leakage concern. There are many factors which were used in addressing the structural and leakage issues associated with any indication that was found. These are:

I) the axial and/or circum-ferential extent of the indication.

2) the estimated depth of the indication,
3) the proximity and type of other indications in the expansion,.
4) the radial distance of the tube from the center of the tube bundle.
5) whether the kinetic expansion was 17" or 22" in length. and
6) the nminimum required axial kinetic expansion length (AKELU) to ensure structural integrity in the event of a MSLB.

The mininmumn required axial kinetic expansion length (AKEL1 ,13 is based on the radial distance of the tube from the center of the tube bundle and also on whether the tube has a 17-inch or a 22-inch expansion.

The determination of the structural adequacy of the tube was based on the measured axial and circumferential extents of the indications. The volumetric indications had both axial and circumferential measurements 12

TR- 151, Revision 0 assigned and were consenratively treated as separate axial and circumferential crack-like indications.

Some tubes had multiple indications in the kinetic expansion region. For tubes with multiple circumferential and/or volumetric indications, the circumferential extents were combined if the indications were located within 1.00" axially of one another. For tubes with multiple axial and/or volumetric indications, the axial extents ibit,.ad u 0en compard ti?

The leakage calculations were based on the estimated depth of the flaws, the axial and circumferential extents of the flaws. and the radial is*t-ncc of t., tUb fro the center of the bundle. An indication was considered to be a leakage contributor only if its estimated depth was >67 percent through wall, as estimated by a plus point probe, and it was located within a certain distance above the Expansion Transition Location (ETL). This distance was based on the AKEL,,J, value as well as the number of flaws and the axial extent of these flaws in the kinetic expansion. If a flaw between ETL + 0" and ETL + 0.25" was detem~ined to be a leakage contributor, then freespan leakage values were used. For the 17" expansions, if a flaw above ETL + 0.25" was determined to be a leakage contributor, then a leakage reduction factor of 25 was applied to the freespan leakage value, (i.e., the freespan leakage values were divided by 25 to obtain the estimated leak rate.) This leakage reduction factor corrects the leakage to account for the reduction in leak rate provided by the presence of the tubesheet. The axial location at which the leakage reduction factor could be applied to flaws in 22" expansions was a function of the radial location of the tube in the tubesheet and the axial location of the indication within the expansion.

The derivation of this kinetic expansion indication evaluation was provided to the NRC in Reference 13. NRC questions on this submittal were responded to in a GPU Nuclear letter to the NRC (Reference 18).

C.3 Other Indications All crack-like indications detected in the freespan, detected in the expansion transition, detected in the first 0.50" of expanded tubing in the upper tubesheet of the 17" kinetic expansions, or the first 5" of expanded tubing in the upper tubesheet of the 22" kinetic expansions were removed from service.

Tube-to-tube support plate wear indications were dispositioned by evaluating their through-wall extent using an Appendix H-qualified technique. There were no tube-to-tube support plate wear marks >40% through wall detected during Outage 1R14.

All manufacturing/burnish mark (MBM) eddy current calls were reviewed from a historical basis before dispositioning.

TMI-1 did not have qualified techniques for evaluating the through wall extent of OD-surface initiating degradation indications other than tube-to-tube support plate wear. Thus, OD indications resulting from tube wall degradation other than tube-to-tube support plate wear (e.g. OD "groov'e IGA. OD volumetric IGA) were "plugged on detection".

D. IN-SITU PRESSURE TESTING D. 1 Pressure Test Process In-situ pressure testing was conducted during the 1R14 Outage to assess the ability of the flaws to withstand a postulated main steam line break (MSLB) event on the last day of the just-completed operating cycle. In addition. in situ testing was perfonned on a large sample of voluhmetric ID IGA flaws in order to assess this flaw population in accordance with the Teclmical Specifications. The tubing was subjected to differential pressure equivalent to normal operating, main steam line break, and Regulator. Guide 1.121 (Reference 11) prescribed differential pressures.

13

TR-151, Revision 0 The testing was conducted using localized area hydraulic pressure tooling to pressurize a specific tube region.

The localized testing is performed through a chamber created by two independent probes that lock into the tube and seal from opposite directions.

All tubes that wr hi situ pressure tested were subscquently plugged.

D.2 Candidate Selection The eddy current test results were reviewed to select flaws for in situ pressure testing from a leakage and structural integrity perspective. To avoid complete reliance on depth sizing by bobbin and MRPC eddy current, other parameters such as voltage response and axial and circumferential lengths were also considered to select flaws for in situ testing.

The EPRI In Situ Guidelines (Reference 19) were used to determine which tubes required in situ pressure or leak testing. The EPRI Guidelines use sequential screening criteria. Sequential screening means that only indications which exceed a threshold value for the first screening parameter are evaluated against the second screening parameter threshold, and only indications that exceed the thresholds for the first two screening parameters are evaluated against the third screening parameter, and so on.

Tables 11-2 and 11-3 show the indications that were selected for in situ testing and the results of the tests.

There were a total of 21 tubes with flaws that were in situ tested (9 in SGA and 12 in SGB) plus tube B65-130 was pressure tested under laboratory conditions (See Table 11-4) and is further discussed in Section III.B.5.

It should be noted that the majority of these tubes did not require testing under the EPRI guidelines and that all tubes screened as requiring pressure testing were pressure tested. Seven of the 21 tubes in situ pressure tested contained indications that exceeded the EPRI screening criteria. The 14 additional tubes were tested to provide a tested population of ID IGA volumetric indications in accordance with the Technical Specifications and its referenced documents (References 1 and 22), or to provide additional assurance that sufficient flaws were tested. The indications that were tested can be divided into five basic categories as follows:

OD Axial Indications Two tubes with axial indications indicative of OD "Groove" IGA were in situ pressure tested (398-1 and B119-2). Both of these tubes had multiple indications located in upper freespan regions. One additional tube (B133-1) had two signals detected at the 12th support plate from the Plus Point inspection. Although the indications in B133-1 were not likely due to tube wall degradation the signals were dispositioned as axial indications as a conservative measure. The +Point coil through wall estimates of tube B133-1 indications were relatively deep, so this tube was pressure tested. Section III.B. 1 provides additional information about tube B133-1.

ID Circumrferential Indications A total of six tubes with ID circumferential indications were in situ pressure tested (3 in SGA and 3 in SGB).

Since all of these flaws were confined within the upper tubesheet. these tests were basically for leakage purposes only.

14

TR-15 1, Revision 0 Mechanical Wear Damage Related to Severed Tube Four tubes were identified in SGB to have wear indications related to severed tube B66-130. Tube B66-130 was severed at the upper tubesheet of the secondary face and had subsequently impacted four adjacent tubes.

Three of these adjacent tubes were in situ pressure tested (B65-129, B66-131, and B67-130). The fourth tube was harvested from theseconda,. side and wa. teted in a laboratory enviroment"(Scc Table 11-4 ad Section III.B.5).

OD Volumetric Indication Tube 59-72 in SGA was in situ pressure tested due to an OD volumetric indication that exceeded the depth threshold for pressure testing.

ID Volumetric Indications Eight tubes were in situ tested due to ID volumetric indications. These tests were performed in accordance with the Management Program for the ID IGA degradation (Reference 22) as referenced in the Technical Specifications. These eight tubes contained 68 volumetric ID IGA indications. One other ID IGA indication was also tested in tube B149-1 although this was not the reason for testing this tube, therefore a total of 69 ID IGA indications were tested. (This tube was tested due to an ID circumferential indication at the kinetic expansion transition.) The main criterion that was used for selecting these tubes was the axial extent of the volumetric indications. The circumferential extents and voltages were also considered in some cases. Two tubes in SGB (B44-75 and B143-43) were selected solely based on the large quantity of indications within the tube. None of the indications in these two tubes required plugging. Based on the large number of indications, however, these two tubes were in situ pressure tested and were subsequently plugged.

A. SCOPE SELECTION During Outage 1R14 TMI-1 chose to initially perform bobbin coil examinations on 100% of the in-service tubes in each OTSG. In addition to the bobbin coil examinations, approximately 39% of the tubes in each OTSG were scheduled for MIRPC examination of the kinetic expansion transition and kinetically expanded region. In order to define a kinetic expansion examination results classification, TMI-1 assigned tubes to groups prior to the Outage. Sample expansion, for the kinetic expansion examinations was then based on the results of each examination group. No sample expansion was possible for the bobbin coil examinations since all of the in-service tubes were examined.

Tables III-1 through 111-4 provide the examination categories, quantities, and reasons for examination. Figures III-1 through 111-6 provide tubesheet plots of the kinetic expansion, lower tubesheet., and sleeve examination locations.

TR-151, Revision 0 B. EXAMINATION RESULTS B. I Tube Examinations (unexpanded Region)

Appendix II of this report provides a listing of detected indications in tubes, sleeves, and plugs that were in service during Cycle 13. The examination results were reviewed to determine Technical Specification classification requireccnts pcr Technical Speclifcatiuon 4.19 and to deternine whether other conditions were present which could be indicators of other damage. Volumetric ID IGA indications were evaluated for signs of growth as required by the Plant Technical Specifications and AmerGen Energy Report TM 01-00328 (Reference 22). No secondary side miscellaneous damage such as missing support plates was observed.

It should be noted that previously plugged tube B66-130 failed at the upper tubesheet secondary face and caused significant damage to adjacent in-service tubes. The tube B66-130 condition is discussed later in this report.

Since the bobbin inspection sample included 100% of the in-service tubes in each generator, the category classification is for documentation and notification purposes only and could not affect further bobbin coil inspection sample expansion criteria. The three categories are as follows:

C-1 Less than 5% of tubes inspected are degraded and none are defective C-2 One or more but not greater than 1% of tubes inspected are defective or between 5-10% are degraded C-3 More than 10% of tubes inspected are degraded or more than 1% are defective The results of the 1R14 bobbin inspection at TMI-1 are classified as C-2 for each steam generator based on having one or more but not greater than 1% defective tubes. For purposes of this classification, the following limits applied:

A tube was classified as defective, degraded, or imperfection in accordance with the TMI-1 Technical Specifications. Every tube with indications confirmed by MRPC was reviewed and assigned a classification.

For tubes with multiple indications, the tube was classified based on the most limiting indication detected in that tube.

TRENDING OF ID INDICATIONS During the 1R14 inspection, a new Technical Specification Amendment No. 237 (Reference

2) was implemented to address the volumetric ID IGA indications located in the non-expanded sections of tubing.

In accordance with the Teclmical Specification, two different statistical tests must be performed on three different eddy current parameters. If all of these tests are passed, then the assumption of no growth is considered valid and can be used in the performance of the operational assessment. If any of these tests are unsuccessful, then a cycle-specific growth model must be developed and used for the operational assessment.

The three eddy current parameters that must be evaluated are the bobbin coil estimated depths, the bobbin coil voltages, and the circumferential extents from the MRPC inspection. The two tests that must be performed are the Sign Test and the Paired t-Test. For each of these tests, the growth is evaluated against a small positive change for the three eddy current paranmeters. (The use of small positive values reduces the possibility that random process error alone could result in mistakenly concluding that actual physical growth has occurred.)

These small positive reference values are lTW estimated bobbin depth. 0.05 bobbin volts, and 0.01 circumferential extent.

In addition to the Sign Test and the Paired t-Test, the Extreme Value Test was used to help identify outliers in the data. The main purpose of this test is to identify indications that: 1) exhibited abnormal growthi during the previous cycle of operation, or 2) may have been mis-analyzed or mis-characterized in either the current or the previous outage.

The results of the Sign Test and the Paired t-Test are shown in Table 111-5. This table shows the results for both steam generators combined. As shown in the table, the Sign Test and the Paired t-Test were passed for all 31

TR-151,, Revision 0 three of the eddy current parameters. Per Reference 22, the data from both steam generators should be combined prior to performing the tests.

In summary, the statistical values observed for the bobbin coil voltage and through wall measurements of volumetric ID IGA are very much in line with similar evaluations performed for prcvious outages and continue to suppoft a no growtih concIusioni.

TR-151, Revision 0 LEAKAGE CALCULATION FOR VOLUMETRIC ID IGA Reference 22 describes the method for estimating the postulated primary-to-secondary leakage for the ID IGA indications located in the non-expanded regions of the tubing. This process uses a hypergeometric distribution to determine the number of indications that must be assumed to leak. It is based on the total number of indications detected, the number of indications Lhat have been in situ leak testcd.

Lile and the number of leaking flaws wit' tested population.

....... n,, 212, dnctce-n volumetric Pr t'.1..hdications had been successfully leak tested prior to the 1R4i outage. However, for this analysis, no credit was taken for these previous leak tests. During 1R14,. a total of 69 volumetric ID IGA indications were leak tested (40 in SGA and 29 in SGB). None of the tested indications showed any signs of leakage. Per Reference 22, the in situ tests performed in one steam generator can also be applied to the other steam generator. This is because both of the steam generators share a common primary coolant system, and they were both damaged simultaneously by the sulfur intrusion into the primary system in 1981. Therefore, 69 successful in situ tests will be credited for both steam generators in the leak rate calculation.

To determine the leakage contribution for the volumetric ID IGA indications, each indication is first assigned a leakage value based on its axial extent as shown in Reference 22. Table 111-6 shows the assumed leakage values as a function of the measured axial extent of the volumetric indication. After determining the leak rate for each indication, the average leak rate per indication was calculated by dividing the total leak rate by the number of detected indications in each steam generator.

Using the number of indications detected and the number of in situ tests performed as inputs to the hypergeometric distribution, the number of assumed leaking indications was adjusted until a minimum confidence level of 95% was obtained. This number of assumed leaking indications in each steam generator was then multiplied by the average leak rate for that steam generator to determine the leak rate due to volumetric ID IGA. Table 111-7 provides a summary of the inputs and results of this calculation. As shown in the table, the calculated leak rates for the as found condition of the tubes were small (<0.047 gpm for SGA; and <0.004 gpm for SGB) due to the extensive in situ leak testing, without leakage, that was performed during the 1R14 outage.

TR-151, Revision 0 TRENDING OF WEAR INDICATIONS During the 1R14 inspection, a new process was implemented where some of the wear indications were depth-sized with the bobbin coil probe. In accordance with the Analysis Guidelines (Reference 20)., all of the following criteria had to be met in order for a bobbin depth to be assigned. if one or more of these five criteria were not

  • 1 ... * .. "iW Tr\-T _ tn,."lT -r.* . , met, thcn the signal was reported as iNQ ad .an....... eai.iiatiion was performed on that location.
1) the bobbin estimated depth must be less than 30TW.
2) the indWcation must bc located at the 01 S through 13) SLPPorI plates,
3) the indication must have been reported as wear during the previous inspection,
4) the change in the phase angle from the previous inspection must be less than 10 degrees, and
5) the change in the voltage from the previous inspection must be less than 0.50 volts.

In the previous 13R inspection, wear indications were depth-sized with MRPC.

Table 111-8 provides a summary of the growth of the wear indications based on the voltages and depth estimates from both the bobbin coil and the MRPC probes. Since bobbin depths were not reported during the 13R examination, the bobbin depths used for this growth analysis were obtained from Reference 23, a study, which looked back at the 13R examination data. As shown in the table, no significant growth of the wear indications has occurred for the operating period listed.

For the bobbin and MRPC depth estimates and the bobbin voltages, no significant differences between the two steam generators were apparent.

Based on the results of this analysis, there was no significant growth of dents during the previous operating cycle.

Tables 111-9 and III-10 show the voltage and voltage growth statistics based on the locations of the dents. As shown in the tables, the average growth was 0.04 volts in OTSG- A and 0.23 volts in OTSG-B. In both steam generators, the largest growth rates occurred in dents at the secondary face of the lower tubesheet. The secondary face of the lower tubesheet, however, is also the location of the largest dents. As a percentage of the dent voltage, the growth of the dents at the lower tubesheet is insignificant.

Three tubes (A59-72. B9-62. and B28

42) had OD volumetric "Patch-Like" IGA typical of OD volumetric IGA found in other OTSG's. Two tubes (B98 1 and BI 19-2) had OD "Groove IGA" typical of other OTSG's and those previously observed at TMI-1. Four tubes (B65-129, B65-130. B66-131, and B67-130) were damaged by previously plugged tube B66-130.

(Conditions surrounding severed plugged tube B66-130 are discussed later in Section III.B.5 of this report.)

Tube B133-1 was plugged for two eddy current indications that were classified as "SAT"at the 12"' tube support plate. The indications were conservatively dispositioned as "'SAI" indications because several of the Resolution Analysts were of the opinion that the ECT signals could be indicative of tube wall degradation. This was an unusual indication that was most likely due to a very shallow tube-to-tube support plate wear indication or a change in secondary side deposit condition. This conclusion is based on the following facts:

"* At 300 kIIz the +Point coil indication phase angle measurements suggest a high through wall flaw

"* The amnplitude of the indication signals do not suggest a deep flaw

"* The signals observed are in the same relative phase plane as "general" tube noise observed at support plates

"* There is no evidence of phase shifi during entry into and exit away from the signal (commonly referred to as "walking" into and away from the flaw)

"* Phase rotation of the 100 kHz signals suggest shallow through wall or possible debris 38

TR-151, Revision 0

"* The location of the signals are slightly off the land contacts

"* Confirmation flaw signals are not evident on the 0.80" high frequency or 0. 115" mid frequency pancake coil probes (high through wall flaws should be easily detectable with these probes)

"* Comparison of the historical bobbin signal response indicates that there has been no significant change in the signal

"* Post in situ eddy current examination results indicated no change The Outage 1R14 Condition Monitoring and Operational Assessments considered the impact of the above described degradation (see Section V of this report).

B.2. Kinetic Expansion Examinations Appendix II includes indications located at ETL (Expansion Transition Location) +0.0" or above as a result of rotating probe examinations.

Structural Integrity The results of the kinetic expansion inspection yielded six tubes that exceeded the conservative criteria for kinetic expansion structural integrity (See Tables 111-15 and lI1-16 that list "Kinetic Expansion Indications" under "Reason For Plugging"). Four of these were in OTSG-A tubes and two of these were in OTSG-B tubes. Thirteen tubes were preventively plugged because they had circumferential indications that were located between ETL +0.0" and ETL +0.50" (ETL is the axial tube location that is identified by the transition from the expansion transition to fully expanded tubing; specifically ETL +0.0" corresponds to that point where the tube is fully in contact with the tubesheet bore.).

Approximately 39% of the in-service kinetic expansions were in the original plan to be inspected. Therefore, there was a possibility of a scope expansion to include the other tubes not examined. The tubes included in the sample were segregated into IS (3%), 2S (6%), and 4S (12%) samples before the outage. In addition, some tubes were scheduled for monitoring of kinetic expansion indications as described in. Tables 111-12 and 111-13, or were required to be examined by the Technical Specifications. These tubes were not part of the iS, 2S, or 4S sample because all tubes meeting the applicable selection criteria were scheduled for examination.

Tables 111-12 and 111-13 show the kinetic expansion examination sanmple results. The "Sanmple Escalation Poinft in the tables is the number of tubes, with defects exceeding the structural criteria, which would have resulted in expanding the inspection to 100% of the in-service tubes. As shown in the tables, six tubes had indications that exceeded the criteria for structural integrity. None of the samples reached the sanmple escalation point. Therefore.,

no increases in examination scope were necessar_,.

Theoretical MSLB Leakage Calculations Based on conservative criteria used to estimate theoretical MSLB leakage, there were a total of 147 leakage contributing indications (92 in SGA; 55 in SGB). Only 9 of these indications (5 in OTSG-A; 4 in OTSG-B) were "full" leakage contributors. The remaining leakage-contributing indications had the leakage reduction factor applied owing to their locations within the tubeshect expansions. Of the 147 leakage contributors. Il l were in tubes with 17" expansions.

All of the in-service kinetic expansions have now been inspected with Plus Point in one of the last three outages and previous leakage-contributing indications were inspected again in 1R14. In addition, the ID IGAISCC in the kinetic expansions is not growing. Therefore, the indications from the 12R and 13R inspections that were determined to not be leakage contributors can be assiuned to still be in the same condition. (It should also be noted that the ID IGA indications below the kinetic expansion are also not growing. This is supported by the Sign Test and the Paired t-Test results as discussed in Section II.B. 1.)

TR-151, Revision 0 Table 111-14 summarizes the results of the theoretical leakage calculations. This taIble includes an "as-found" leakage value and an "as-left" leakage value for each steam generator. The as-found leakage includes ,all lekage contributors before plugging. The as-left leakage includes all leakage contributors that were returned to senrice for Cycle 14.

  • The "as-found" leakage includes all leakage contributors before plugging. All of the kinetic expansions were examined using eddy current over outages 12R, 13R, and 1R14 and all previous leakage contributors were re-inspected during 1R14. Therefore, no projection of the leakage for the un-inspected tubes is required.
    • The 'as-left" leakage includes all leakage contributors that were returned to service for Cycle 14.

B.3 Lower Tubesheet Examinations No service induced degradation was identified during these examinations.

B.4. Sleeve Examinations No service induced degradation of 1-690 sleeves or of parent tubes with installed sleeves was identified during any of these examinations.

B.5. Severed Tube B66-130 During the 1R14 inspection, four neighboring tubes of tube B66-130 were found to have indications of wear in the upper span just below the upper tubesheet. The four tubes affected were B65-129, B65-130, B66-13 1, and B67 130. These tubes are all adjacent to plugged tube B66-130. Plus Point inspection of the affected tubes confirmned the presence of long wear indications in the upper span just below the tubesheet. The wear indications ranged from about 2.75" to about 8.3" in length.

In order to evaluate the root cause for the wear on the subject tubes, the upper tubesheet plug of tube B66-130 was removed to facilitate bobbin coil eddy current and video examinations. The bobbin coil inspection of the tube produced very noisy data that was later determined to be due to the fact that the tube was expanded significantly (i.e., -swollen" beyond nominal tube dimensions). The video inspection from the upper tube end confinned that the tube was severed 360 degrees at the secondarv face of the tubesheet. Based on the pattern of the affected tubes and subsequent visual examinations, it was confinred that tube B66-130 was severed and had impacted the adjacent tubes listed above.

41

TR-151, Revision 0 An investigation was performed to determine the root cause of the circumferential failure of tube B66-130. The investigation concluded that the circumferential failure of tube B66-130 was a combined result of the following factors.

"* internal pressurization due to mechanical plug "leak-by" caused the tube to swell during plant heat up(s) and become restrained at both the 15"' tube support plate and the secondary face of the upper tubesheet.

"* The upper span region is located in a high secondary steam velocity flow and velocity profile region (i.e., a periphery tube with higher velocity). When the tube became restrained at its upper span, the tube's damping capability was reduced resulting in susceptibility to flow induced vibration (FIV) fatigue.

"* The presence of existing tube degradation (OD IGA) at the secondary face of the upper tubesheet region became an initiating location for FIV fatigue failure.

Based on the finding of a swollen and severed plugged tube during the course of the inspection, a decision was made to deplug additional tubes in both OTSGs. An extensive inspection of hundreds of deplugged tubes identified a total of 28 other tubes that were swollen as a result of the plugged tube over-pressurization effect. Of these 28 additional swollen tubes, one additional deplugged tube (A2-24), was identified with a circumferential severance that was located at the 15'b TSP. Another swollen deplugged tube, B150-14, was identified with an axial burst between the 15"' TSP and the upper tubesheet. Tube B66-130, however, was the only plugged tube found to have damaged its adjacent tubes.

To address the significance of the wear scars in the four adjacent in-service tubes, in situ pressure testing was performed on three of the tubes (365-129, B66-131, and B67-130). The fourth tube, B65-130, had the deepest measured depth and was tested in a laboratory environment. Tubes B65-129 and B67-130 showed no signs of leakage at in situ test pressures up to 4350 psig (3xNOPD). Tube B66-131, however, failed at the 3xNOPD test pressure. During the final test step for B66-13 1, the tube held pressure at 4360 psig for approximately 1 second with no leakage. After this, the pressure dropped to approximately 450 psig (calculated to be less than 100 psig at the defect) with leakage measured at 3.2 gpm. Video inspection of this location after the test verified that the tube had failed (axial fishmouth) in the area of the wear scar.

In addition to the in situ pressure tests. a secondary-side tube harvest of the severed tube B66-130 as well as two of its neighbors (365-130 and B66-13 1) was performed via the secondary-side manway. As mentioned above, tube B65-130 was pressure tested in the laboratory. As the pressure was being increased to the MSLB test pressure (2900 psig) in tube B65-130, the defect opened and the pressure dropped to zero. The maximum pressure observed in B65-130 was 2979 psig.

Corrective actions were taken during 1R14 to mitigate the occurrence of swollen tubes and the effects of swollen tubes during future operation. The investigative evaluations concluded that this failure is not a likely mechanism in the lower tube span of plugged tubes due to reduced FIV loading. The corrective actions taken to prevent recurrence of tube severance in a plugged tube and to mitigate the impacts of the plugged tube over-pressurization effect were:

  • De-watered tubes prior to plugging and re-plugging.

"* Stabilized the upper span region of all tubes that were plugged, or ensured that non-stabilized plugged tubes are surrounded by either stabilized plugged tubes or sleeved tubes.

" Tubes that were swollen as a result of the over-pressurization were plugged and stabilized with full-length stabilizers with the following exceptions: Severed tube B66-130 was not required to be stabilized because the upper span region of the tube was removed and all surrounding tubes were either stabilized and plugged or had the upper span removed in order to access tube B66-130 for removal. Swollen tube B150-14 could not be stabilized over its full length because of an obstruction (stuck eddy current probe) near the 7h'TSP.

42

TR-151, Revision 0 B.6. Plug Examinations The eddy current examinations identified no plug pressure boundary degradation. The eddy current examinations of the upper tubesheet Westinghouse rolled plugs identified 23 plugs in OTSG-A and 19 plugs in OTSG-B that and B)7-5'at reain were obstructed

repair activities performed in the early 1980's. It is acceptable for these plugs to remain in service because there was no degradation identified from any of the Outage 1R14 plug eddy current examinations and the end damage is very minor in nature.

The scheduled plug visual examinations identified three upper tubesheet Westinghouse plugs (A2-1 I, B78-63, and B77-75) that had identified plug end damage. All three of these plugs were removed during Outage 1R14.

C. IN-SITU PRESSURE TESTING RESULTS As shown in Tables 11-2 and 11-3, two of the tested locations showed leakage. Tube B66-131 was tested due to wear damage associated with severed tube B66-130. During the final test step for tube B66-131, a pressure of 4360 psig was reached and held for approximately one second with no leakage. After this, the pressure dropped to approximately 450 psig (calculated to be less than 100 psig at the defect) with leakage measured at 3.2 gpm. Video inspection of this location after the test verified that the tube had failed (axial fishmouth) in the area of the wear scar. As a result of this failure, tube B65-129 was added to the test list. Tubes B65-129 and B67-130 were both in situ pressure tested with no leakage detected. Tube B65-130, the tube with the worst mechanical wear damage based on ECT, was harvested from the secondary side and was tested in a laboratory environment. As the pressure was being increased to the MSLB test pressure (2900 psig) in tube B65-130, the defect opened and the pressure dropped to zero. The maximum pressure observed in B65-130 was 2979 psig.

One of the circumferential indications (A53-46) leaked slightly at a very high test pressure. The indication in this tube was an ID circumferential indication located at ETL -1.43". This tube has a 17 inch kinetic expansion.

Therefore, the circumferential indication is located more than 5 inches into the tubesheet and is not a concern for burst. The leak rate for this tube was measured as 0.014 gpm based on a two minute hold time, but this was at an extremely high pressure of 6450 psig. This tube, as well as 4 other tubes with circumnferential indications, was tested at pressures significantly above 3xNOPD in order to achieve additional axial load. This was done because the axial pull in situ probe got stuck in tube B80-31 (which was the first circumferential indication that was tested).

The test in tube B80-31 was completed successfully with an applied axial load. However, the probe was found to be stuck in the tube upon completion of the test. Due to this probe getting stuck, it was decided that, for the remaining circumferential indications, the additional axial load would be achieved by over-pressurizing the tubes.

There were tlree tubes with circumferential indications on the original in situ test candidate list. Since the leak rate in tube A53-46 was so small, there was no likelihood of violating the NEI 97-06 performance criteria and, therefore, no requirement to test additional circumferential indications per the EPRI Guidelines. However, as a conservative measure, three additional circumferential indications were added to the test list, giving a total number of six circumnferential indications tested.

The in situ pressure test results are provided in Tables 11-2 and 11-3 of this report.

IV. REPAIRS PERFORMED A. TUBES PLUGGED DUE TO EDDY CURRENT RESULTS As a result of eddy current indications evaluated during Outage 1R14 examinations twenty-seven (27) tubes in OTSG-A and thirty-one (31) tubes in OTSG-B were plugged. These tubes are listed in Tables 111-15 and 111-16 below:

TUBES PLUGGED TO PREVENT SEVERED TUBE FAILURE Plugged tubes that were not previously stabilized were de-plugged and stabilized in order to prevent re-occurrence of tube-to-tube wear similar to that which occurred in the tubes adjacent to plugged tube B66-130. Plugged tubes that could not be stabilized and had not had upper tube sections removed during a tube pull process were "captured" to prevent damage to adjacent in service tubes should a postulated plugged tube severance occur. These tubes were "captured" by plugging and stabilizing tubes adjacent to the non-stabilized plugged tubes. In OTSG-A 149 tubes were plugged and stabilized in order to capture tubes that were plugged but not stabilized. In OTSG-B 117 tubes were plugged and stabilized in order to capture tubes that were plugged but not stabilized. Table 111-17 below provides a listing of tubes that were plugged in order to capture adjacent tubes that were plugged but not stabilized.

TR-151, Revision 0 The total number of tubes plugged in OTSG-A is 1.512 (9.74% of the 15.531 tubes), and the total number of plugged tubes in OTSG-B is 552 (3.55% of the 15.,531 tubes).

The 80" sleeves installed in the TMI-1 OTSG's affect primary coolant flow and alter the effective plugged percentage of tubes. Per Reference 15, 6.7 tubes with 80" sleeves installed are hydraulicalb, equivalent to I plugged tube:

"° The effective plugging percentage of OTSG-A, considering the 1R14 Outage tube plugging and the effect of its 248 in-service sleeves, is now 9.97%. [ (1512 + (248/6.7)) / 15531 = 0.0997 ]

"* The effective plugging percentage of OTSG-B, considering the 1R14 Outage tube plugging and the effect of its 253 in-service sleeves, is now 3.80%. [(552 + (253/6.7)) / 15531 = 0.0380]

C. PLUGGED TUBE REPAIRS Corrective measures were completed in order to prevent future damage to tubes similar to the damage that occurred as a result of the failure in plugged tube B66-130. These corrective measures are summarized below:

  • Deplugged tubes were dewatered prior to their re-plugging. This minimized the water remaining within the plugged tubes that could subsequently over-pressurize the tube.
  • Plugged tubes were stabilized in their upper spans from the upper tubesheet through the 14th tube support plate, or additional tubes were plugged and stabilized to ensure that non-stabilized plugged tubes are surrounded by stabilized, plugged tubes, or sleeved tubes.
  • 27 of 29 swollen tubes were stabilized with full-length stabilizers and plugged. Tube B 150-14 was stabilized only in the upper tube span due to a stuck eddy current probe near the 7h TSP. Severed tube B66-130 was not stabilized because the upper span region of the tube was removed as part of the investigation, and all surrounding tubes were either stabilized and plugged or had the upper span removed in order to access tube B66-130 for removal.

V. CONDITION ASSESSMENTS A. CONDITION MONITORING Condition monitoring evaluations consider the "as found" condition of the steam generators, and the ability of the steam generators to withstand hypothetical plant transients over the course of the operating cycle prior to the outage. The 1R14 Outage exanminations determined that swollen, plugged tube B66-130 became circunmferentially severed and impacted four of its adjacent tubes during the prior cycle. The wear damage on these adjacent tubes was of sufficient extent that two tubes did not satisfy the planfs steam generator program requirements for leak/burst integrity at three time the plant's normal operating differential pressure (i.e., 3NODP). Thus, the tubing failed its condition monitoring requirements. A Licensee Event Report (Reference 14) was submitted as a result of this condition.

Aside from the swollen, plugged tube condition described above, the following items are also pertinent to condition monitoring evaluation:

The primary-to-secondary leakrate from the TMI-1 steam generators during the cycle preceding the 1R14 Outage was very low. During the last week of the operating cycle the calculated leakrate was less than 1.5 gallons per day.

During the outage all of the in-service tubes were inspected using eddy current probes. The eddy current test results were screened in accordance with the EPRI Guidelines to select flaws for in situ pressure testing from a leakage and structural integritý perspective. Successful testing of the screened flaws would then provide assurance that the remaining flaws would maintain structural and leakage integrity during a postulated MSLB, In-situ pressure testing was conducted during the 1R14 outage to assess the ability of the flaws found during the eddy current inspections to withstand a postulated Main Steam Line Break (MSLB) event on the last day of the just completed operating cycle. As described in Section 11 the tubing was subjected to pressure loads corresponding to Normal Operating. Main Steam Line Break. and 3NODP. Tables 11-2 and 11-3 of this document provide detailed 49

TR-151, Revision 0 information on the eddy current results for the tubes and indications selected for in-situ pressure testing. Table III 4 provides information on a tube (B65-130) that was pressure tested under laboratory conditions. Seven (7) in situ pressure tested tubes had indications exceeding the EPRI In Situ Testing Guidelines screening criteria, and a total of 21 tubes were in situ pressure tested. Based on the 1R14 in situ pressure testing and examination results. in service tubes (with the exception of B65-130. which is a tube adjacent to tube B66-1130). would have maintained structura-1 aill lc a'Ke interglity, uLrlin a posUbLIatdLU i.vLB a.JUJCIL Oth UISl Ui I ll cyuci plc~dinig tUh tyua Od outage.

As discussed in Section II.C.2, eddy current indications in the upper tubesheet kinetic expansions were assumed to leak during a postulated MSLB if their through wall extent (as estimated by a Plus-Point coil) was 67% TW or greater. Each of these potential "leakage contributor" indications was conservatively evaluated to determine the volume of primary-to-sccondary lcakage associated with that indication if an MSLB had occurred. These accident induced leakage volumes were summed for each of the indications to predict the hypothetical leakage from all of the expansions. The resulting calculated leakage was considerably less than that allowed by the plant's FSAR.

(See Table 111-14.)

As discussed in Sections II.D and III.C, a large sample of volumetric ID IGA indications was in situ pressure tested, with no leaks, to demonstrate that the remaining population of volumetric ID IGA indications will leak less than a very small amount. This testing was done in accordance with the plant's Technical Specifications to evaluate theoretical leakage of the population of ID IGA indications during accident conditions.

All of the plant's in-service steam generator tubes were inspected. In-situ pressure testing was a primary tool to demonstrate the ability of the freespan tubing to withstand accident-induced loads at the end of the just-completed operating cycle. The kinetically expanded tubing was examined with MIRPC probes and an assessment of the postulated leakage was conservatively developed. The degradation observed during the 1R14 Outage was evaluated in a manner consistent with NEI 97-06 and the EPRI Guidelines. The evaluations indicated that., with the notable exception of the tubes adjacent to plugged tube B66-130, the observed degradation did not present serious challenges to the structural margin requirements at the end of the last cycle of operation, or challenge the plant's leakage integrity limits. The degraded integrity of the tubes adjacent to plugged tube B66-130 is the subject of LER T2001-003-00 (Reference 14).

B. OPERATIONAL ASSESSMENT As described in previous sections, in response to the plugged tube B66-130 severance issue, the TMI-l IR14 Outage resulted in 266 tubes (149 in the "A" OTSG; 117 in the "B" OTSG) plugged in order to surround previously plugged tubes with stabilized plugged tubes. In addition, tubes (4 in the "A" OTSG; 9 in the "B" OTSG) were preventively plugged. Forty-five tubes (23 in the "A" OTSG: 22 in the "B" OTSG) were plugged as a result of the eddy current examination results.

ID-initiated indications were the predominant eddy current examination result for which TMI-1 steam generator tubes were plugged. The I.D. indications are believed to be renmants of the thiosulfate damage that occurred to the ID surfaces of the tubes in 1981. As discussed in Section III.B.1, the growth rate for ID IGA indications/flaws is believed to be zero and the ID IGA indications requiring repair were generally the result of N/vRPC examinations in areas not previously examined or were due to variability in the eddy current examination process.

TMI-1 has now examined all of the steam generators' in-service kinetic expansions over the last 3 outages with MIRPC probes. As reported in Section III.B.2. TMI-1 compared the kinetic expansion inspection results of the last three outages and has concluded that the indications within the kinetic expansions are not growing.

An operational assessment of the 1R14 Outage inspection results was successfully performed using methods consistent with NEI 97-06 and the EPRI Guidelines. The corrective actions undertaken in response to the severed.

plugged tube issue should eliminate the possibility of an in-service tube being similarly impacted during forthcomuing cycles. When considering Outage 1R14 corrective actions, indications detected during Outage 1R14.

and indications assumed to remain in service following the 1R14 Outage. the probability of rupture/burst of a tube under postulated TMI-1 MSLB accident loads supports full cycle operation. The operational assessment report is available at the site for NRC staff inspection, if desired.

TR-151, Revision 0 VI. CONCLUSIONS Based on the results of the 2001, Outage 1R14 ECT examinations, tube pulls, in situ pressure testing, and data evaluations, TMI-1 was able to reach the following conclusions:

1. Evaluation of the ID IGA indications continues to indicate no trend of ongoing degradation.
2. "Groove iGA" is an active damage mechanism at TMI-1. However. the small number of indications and growth rates continue to support full cycle operation.
3. Tube-to-tube support plate wear is not an active damage mechanism.
4. Lower tubesheet OD degradation was not detected during examination of the most susceptible regions with MRPC probes.
5. The installed Inconel 690 sleeves, and parent tubing, continued to perform without degradation.
6. OD volumetric IGA (similar to OD volumetric IGA in other OTSGs) continues to be detected at TMI-1 in small numbers and is not a tube integrity issue based on eddy current examination and in situ pressure testing results.
7. As a result of the plugged tube B66-130 severance, root cause/condition monitoring evaluation determined that OTSG-B did not meet requirements for safety margins against burst during an MSLB during the last several days of Cycle 13. (Refer to Reference 14).
8. Repairs performed during Outage 1R14 eliminated severed plugged tubes as a potential damage mechanism for adjacent in service tubes during future cycles.
9. Operational assessment evaluation determined the steam generators are acceptable for full Cycle 14 operation.

Code Definition indication Not Found -- this designator is used onliy if a previously identified indication is INF not recurring. In this case, a tubing number check shall be performed and tubesheet signature shall be reviewed to verify that the correct tube is being examined.

N indication Not RItportab*le - an iHdicaiun 'uhat has been previously reportLdU .u.t uUh nut meet current reporting criteria.

Irregular Roll - a sleeve roll which displays irregularity not associated with degradation.

IRR An example of this may be a roll with a tapered expansion, a much smaller or larger expansion than normal, a very short expansion, or a case where the two lower expansions overlap resulting in what appears to be one long roll.

LEN Length Measure -- denotes that the measurement in the Volts field is the axial length measurement of an indication in inches.

Loose Part Indication -- used to identify tube wall degradation that is believed to be a LPI result of contact with a loose part. The loose part may or may not be present. Adjacent tubes shall be checked to determine if other tubes have been affected by the loose part.

MAI Multiple Axial Indication -- an MRPC call determiined from indication morphology Machine Burnish Mark (or Manufacturing Buff Mark) -- an indication believed to be MBM produced from a condition resulting from final hand polishing or grinding operations during manufacture to remove imperfections on the tube's outer surface. An indication must have repeatable history to be considered an MBM (MiRPC examinations only).

MCI Multiple Circumferential Indication -- an MRPC call detenmined from indication morphology Mixed Mode Indication -- an MRPC call determined from indication morphology. This code shall only be used if the indication morphology reflects a situation which would lead the analyst to believe that an axial and circumferential indication have linked in some fashion (for example a T or L shaped crack-like indication).

MVI Multiple Volumetric Indication -- an MRPC call determined from indication morphology No Detectable Degradation -- designator used for an examination that indicates that the NDD region inspected is free of detectable degradation. The actual entry of the code is not required.

No Degradation Found -- designator used for a rotating exanmination to disposition an area of interest that another technique has flagged as needing to be inspected, but when NDF inspected with the rotating technique no degradation was identified. The actual ent.' of the code is required along with the location identified by the implementing examination and the actual extent from the rotating techmique.

NEX No Expansion -- no roll or expansion where one should be.

NFC No Final Calibration -- designator used to identify that the calibration run at the end of a calibration group was not perforned.

Non-Quantifiable Indication -- an ET signal identified by the bobbin analyst as possibly containing an indication: however, due to noise, lack of multi-frequency channel NQI correlation, or other signal peculiarities, the analyst cannot sufficiently interpret the signal to draw any conclusion. This is an interim disposition.

NSY Noisy Tube -- An area of the tube that is too noisy to properly evaluate exanination data (MRPC examinations only).

OBS Obstructed Tube -- used only if the acquisition operator has identified the tube as being unable to pass tie probe due to a restriction or blockage.

Prior Bobbin Analysis -- code assigned to a specific data record to provide a means of PBA clearing the record through data management without re-reporting indications already reported during a previous bobbin coil scan of the satme area.

Plug End Anomaly - indications located completely outside the plug pressure boundanr.

For rolled plugs. this area includes only the heel transition and outboard end of the plug.
