INTRODUCTION On September 8,1995, TMI-l was shut down for Refueling Outage llR. During this refueling outage, GPUN performed Eddy Current (ECT) examinations of the Once Through Steam Generators (OTSGs).
The scope of the examinations included tubing and sleeves. The exanunations were required by TMI-l Technical Specification 4.19 (Reference 1), commitments to NRC Generic Letter 95-03 "Circumferential Cracking of Steam Generator Tubes" (References 2 and 3) and GPUN engineering requirements The sleeve examinations were performed in response to Generic Letter 95 03 and to obtam baseline information with the plus point probe.
During Outage 11R 3791 examinations were performed on 3671 tubes and 232 examinations were performed on 128 sleeves in OTSG-A. In OTSG-B,3783 exanunations were performed on 3665 tubes and 256 exanunations were performed on 128 sleeves. As a result of eddy current indications evaluated during these examinations one (1) tube in OTSG A and five (5) tubes in OTSG B were plugged. These tubes included:
OTSG/ ROW / TUBE Reason Plassed A-66-1 This previously identified (ISI) degraded tube (which had been previously sleeved) had an inside diameter (l.D.) indication that increased from 37%
through wall (T.W.) in Outage 10R to 43% T.W. in Outage 11R. The location of the indication was 27.5 inches above the 4th support plate (which is outside the installed sleeve area).
B-7-42 This previously identified (ISI) tube had an I.D. indication that increased from 37% T.W. to 40% T.W. between Outages 10R and !!R. The location of the indication was 11.4 inches above the 13th support plate.
B-45-118 This tube was identified dunng a bounding erammanon in the 12%
Technical Specification Sample Set. A 44% T.W. defect from tube to tube
~
support plate wear was found at the 14th support plate.
B-46-117
. This tube was identified during the 12% Technical Specification Sample Set.
A 42% T.W. defect from tube to tube support plate wear was found at the 12th =>aaaet plate.
B-120-42 This previo asty identified (ISI) degraded tube had an outside diameter (O.D.) volumetric type indication that increased from 35% T.W. in Outage 10R. 'to 44% T.W. in Outage llR. The location of the indication was 14.5 inches above the 4th support plate.
B-126-58 This tube was identified during the 12% Technical Specification Sample Set.
A 43% T.W.1.D. defect was found at a location 29 inches above the 15th support plate.
This brings the total number of tubes plugged in OTSG-A to 1269 and the total number of plugged tubes in OTSG-B is now 378.
Prior to Outage 11R alllower tubesheet active B&W Mark-3 explosive plugs were scheduled to be removed from service during Outage 11R. These plugs were all removed from service by welded plugs.
prip tests performed during the outage identified additional lower tubesheet plugs which required repair.
No unplugged tubes leaked on these leakage tests. In OTSG-A one B&W Mark 1 explosive plug was repaired by installing a RWP behind it. In OTSG-B one B&W rolled plug was replaced with a RWP and a Westinghouse plug was replaced with a B&W Inconel 690 rolled plug.
. Attachmenf 1 REVISION 0 PAGES IL METHODS A.-
DATA ACOUISITION The Eddy Current (ECT) Examinations were performed using the Zetec Miz-30-4 Digital Multi-Frequency Eddy Current System with Eddynet 95 Software. The data was directly recorded to hard disks located in the site analysis area and then spooled to the Benicia Cahfornia and Lynchburg, Virginia off-site analysis locations for primary and secondary analysis, respectively.
The ECT raw data and analysis were then transferred to optical disks for site storage.
Data acquisition was performed remotely using the B&W " ROGER" in head manipulators and
' Zetec Model 10D probe pushers. Dual guide tubes were used to the extent practical, however, they were not as productive as had been planned Noise introduced while running two probes simultaneously prevente1 consistent use of the two probe system in order to maintain the high data quality standards desired. The dual guide tube also experienced snorkel problems in the upper head similar to those -~od with single guide tubes. Exanunations were performed from all four (two simultaneously) heads in order to support reqdred examinations. The bulk of L
examinations were performed from the upper heads so as to not interfere with plug repairs being l
simultaneously performed in the lower heads.
I The ECT exanunations were performed using a variety of techniques and probes which were tailored to address the specific area ofinterest being examined. The examinations were i
performed under GPUN survedlance procedure 1300-4B (Reference 4) and are further discussed l
in the following sections. The specific probe models used are listed on Table 11-1.
j A.1 Tube Bobbtn Coal Exanunations The general tube exammatiore of tubing material was performed from the inside diameter of the j
tube using a bobbin coil probe. This probe is the most durable and efHeient probe available and, when used with the proper ECT instrument, allows examination speeds in excess of 40 inches per second. The data from this probe was used to detect tube wall degradation from such mechanisms as Intergranular Attack (IGA), Intergranular Stress Conosion Crackmg (IGSCC),
tube to tube support plate wear and other general degradation. The data was also used to measure tubesheet profiles of tubes which were shop rolled after stress relief and tubes which were known to have gaps (areas of exposed carbon steel tubesheet ligament) in the upper tubesheet above the load beartag portion of the tube in the kinetic expansion All bobbin coil.
examinations were fulllength,unless otherwise noted. For the purpose of this report, fulllength is from the kinetic expansion transition in the upper tubesheet to the roll expansion tninsition in the lower tubesheet.
All examinations were performed with a speed not to exceed 42.6" per second. The.540" diameter probe was used to exanune previously degraded tubes while the.510" probe was used for initial examination of all other tubes. A.490" diameter probe was used to examine areas of two tubes in OTSG-B which would not pass a.510" probe.
I Tubes with indications screened dunng the bobbin coil exammations were re-examined using the logic shown on Figures II-l and 11-2. In summary, this evaluation process ensured that each previously unidentified indication was examined using both a bobbin coil and pancake coil probe (3 Coil MRPC) to characterize the extent of degradation. The basis for this process has been previously documented in References 5,6,7,8 and 9. For previously identified indications, previous 8xl or MRPC exanunations are considered valid unless the bobbin coil indication had changed significantly or a tube to tube support plate wear indication was being evaluated. For ID indications, a change was considered a change in indication classification (i.e., change from
REVISION 0 PAGE6 BVC to assigned percent through wall,' change from degraded tube to a defective tube, etc.) For OD indications, a change was considered to be an increase of g 10% through wall or an increase of t i volt. All flaw like "I" code indications were also examined with the MRPC probe unless side by side comparison of bobt,in coil signals with past indications indicated that the signal had not chang'ed. The combined information from these probes was then factored into the disposition of the tube.
t A.2 Sleeve Bobbin Coil Examinations The unexpanded portion of sleeves and underlying parent tube were exanuned with a1.400" bobbin coil probe to detect degradation mechanisms such as IGA, IGSCC, tube to tube support plate wcar and other general degradation.~ This probe was used for examinations because ofits durability and higher examination speed. The exammations were performed at a speed not to exceed 12" per second because of the probe's tight fit in the sleeves. All examinations were performed from the lower sleeve end to the upper sleeve end unless otherwise noted.
A3 Motorized Rotatmg Pancake Coal (MRPC) Tube Exanunations MRPC exanunations of tubes were performed as diagnostic examinations following bobbin coil examinations or for detection of speciAc degradation types in areas where the higher sensitivity and additional information were desired. Due to the much slower examination speed of the MRPC probe the exanunations were limited to specific areas of the tube (such as the 15th support plate, upper tubesheet secondary face, and kinetic expansion transition for lane / wedge tubes, or a specific support for follow-up exammations due to bobbin coil examination results).
s A.4 Plus Potat Exanunation of Sleeves The expansions (including expansion transitions) of sleeves were examined using a Plus Point rotating probe. The exammations were generally performed from the lower sleeve end to the 15th support plate (which includes the two lower expansions) and an area in the upper tubesheet which included the upper expansion. This technique is required for erammarinn of the lower sleeve end and roll expansion regions only however, all acquired data was evaluated by the data analysts. See Figure II 3 for sleeve configuration.
A.5 8 Coal Profilometiv Examinations Several tubes were examinevi yith 8 coil profilometry to provide additional information on lower tubesheet dents detected during bobbin coil exanunations. This examination was performed using the tubesheet profile bobbin coil calibration standard, which somewhat limited, diameter j
measurement accuracy, but provided excellent information about the profile of the dents B.
DATA ANALYSIS PROCESS I
- The eddy current data analysis was performed using GPUN Procedure 5361-NDE 7209.63, Revision 0 (Reference 10). This procedure is based on the recommendations of the EPRI PWR Steam Generator Inspection CMdelines (Reference 11) and also meets the requirements of the TMI-l Technical Specifications (Reference 1) and the ASME Boiler and Pressure Vessel Code (Reference 12).

B.1 Data Analyst 0=1%%a=
The data analysis process was performed by Rockridge Technologies and BWNT personnel I
qual.fied and certified to at least Level llA, in accordance with their approved program. In addition, these personnel were recognized as Quahfied Data Analysts (QDA) as defined in the l
EPRI PWR Steam Generator Inspection Guidelines, Appendix G. As a supplement to these qualifications, site specific indoctrination and training was attended by all data analyst personnel.
The program included both classroom lectures and hands on pmcuce using eddy current data and experience from both TMI and another B&W designed plant. The training covered generic OTSG degradation mechanisms and examination methods and also epen ally addressed both the bobbin coil and rotating probe methods used at TMI.
l The total indoctrination process encompassed approximately 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> and was conducted by a GPUN Authorized analyst.

]
data. The bobbin coil probe and MRPC tests were considered separate tests and a satisfactory I
score was required for both methods Appendix I is an outline of the~ program.
B.2 Data Analysis Sequence The data analysis process was performed in accordance with the same procedures used for the data analyst indoctrinanon and traimag. The process was performed in three (3) parts with at least two (2) separate data analysts evaluating 100% of the data for each examinauon The only I
excepuon to this was the " profilometry" portion of the examinations (provided for engineering information only). This portaon of the data received only a single analysis with graphic printouts provided. The data analysis process included:
l 1.
Engiary Analvs s The primary analysis included a 100% evaluation of the ECT data (for tubes,100% length is the unexpanded portion of tube from the lower tubesheet roll expansion transition to the upper tubesheet kinetic expansion transition) and the recording of all attributes identified in Appendix II. For rotating probes, such as MRPC, this included evaluation of the examined area using strip chart displays, lissapus displays and terrain plots. This analysis included recording the phase angle, percent through wall, voltage, circumferential extent and locauon of any indications.
2.
Secondary Analysas This analysis was performed in the same manner as the primary analysis.
3.
Resoluuon Analysas To complete the analysis process, the results of both the primary and secondary analyses are reviewed by the designated lead analyst. This review combines the primary and secondary analyses results and also resolves any diseg+=W For this outage this function was performed by a Level III QDA. In the case of indicauons which are reported as pluggable by at least one analyst, but resolved as being non-pluggable, a Level III QDA from both Rockndse Technologies and BWNT were required to concur that the indicanon was not pluggable in nature This concurrence is documented using a "Overruhng Pluggable Indication" report form.
B.3 Data Analysis Software The data for all exammadons was evaluated using Zetec Eddynet Analysis software, Version 27,
[
for primary and secondary analysis because it was most familiar to the production analysts and provided all the required routines necessary for production analysis. Resolution analysis was performed using Zetec Eddynet 95 software, Version 1 because it provided the potential for

~
BA Recording ofIndications Eddy current indications were recorded to permit dispositioning the examination results and to facilitate monitoring the tubes during future exammations. The recorded indications fall into two basic groups. " indications from Tube Wall Degradation" (indications assigned a percent through wall, "BVC" code or an "I" code) and " indications from Possible Damage Precursors" (indications assigned other three letter codes). The specific criteria used to record the indications is dependent upon the type of probe being used. A complete list of all abbreviations and definitions used to classify indications is included as Appendix II.
Indi+ ions from Tube Wall Degradation
+
Generally indications of tube wall degradation are initially recorded during the analysis of the bobbin coil data. When practical, t'ae indications are assigned a " percent through wall" value based on the phase angle of the indications. When the indication cannot be accurately assigned a through wall value, it is assigned a three letter code such as BVC, DNI, DSI, DRI, DTI or NQ1 which indicates the presence of a possible flaw. *In either case, the indication's location, amplitude, signal phase angle and " percent through wall" or three letter code are recorded to permit further evaluation of the tube.
Once the initial screening of the indications is completed, supplemental examinations are performed using the pancake coil probes (3-coil MRPC) if previous data is not available or if the l
indications have changed. For ID indications, a change was considered a change in indication classification (i.e., change from BVC to assigned percent through wall, change from degraded tube to a defective tube, etc.). For OD indications, a change was considered to be an increase of 210% through wall or an increase of 21 volt. All bobbin coil flaw like "I" code indications were also examined with the MRPC probe unless side by side comparison of bobbin coil signals with past indications indicated that the signal had not changed The data from examinations is analyzed and indications are recorded using three letter codes which indicate the approximate i
geometry of degradation or, for tube to tube support plate wear indications only, a percent through wall'is assigned. In general, indntions are recorded as SAI, SCI, MCI, MAI, SVI, or
[
MVI. These codes indicate whether the indication is single (S) or multiple (M), circumferential l
(C) or axial (A), and whether or not a volumetric (V) condition is present. Like the bobbin coil indications, these codes are recorded along with the locations, amplitude and phase angle of the signal.
An exception to the above flow can occur when only a MRPC examination is sch'eduled for a tube and an indication is identified by this exanunation. A bobbin coil exammation is then scheduled for those areas where degradation history indicates an accurate through wall measurement can be made with the bobbin coil probe. The actual analysis process is performed in the same manner as described above.
inAintons from Paesih!* Da===* Precursors i
The analysis of eddy current data also identifies indications which are not 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. These indications are recorded for information only and do not necessarily require follow-up examinations.

REVISION 0 PAGE 9 Indications Recorded Durina Snecialtzed Examinations I
The data analysis for specialized examinations such as MRPC probes requires a process which is I
different than the bobbin coil examinations. In the case of many of these examinations, the data l
is evaluated to confirm a previously recorded indication. As such, the data is recorded to support j
dispositioning a given indication by length, size, depth or location on a case by case basis in accordance with the analysis procedure (Reference 10).
I t
Indication Locations The locations of the ECT indications are recorded to identify their " elevation" or " axial location"
[
in the OTSG tubes. For free span indications, the locations are recorded in inches almve "+" the tubesheet surfaces or tube support plate center. For indications located within or adjacent to the tube support plates, the indications are recorded as "+" or " " from the tube support plate center.
i The relative location of the tubesheets and tube support plates are shown in Figure 114.
B.5 Data Management Two separate data management systems were used to assure all indications were documented and dispos.tioned appropriately. The examination results were obtained from the Eddynet report files and loaded into the data management systems used during the outat,e. The Rockridge Data l
Management system was updated by Rockridge personnel while the ISIS Data Management system was updated by GPUN personnel. Final results reports from the two systems were then compared to address any inconsistencies betweers the two systems.
B.6 Dispositsomag of Results Generally the combined results of the bobbin coil and rotating probe examinations are used to disposition the individual tubes. This dispositioning process may involve data which was analyzed by several different data analysts. Since the various techniques are complimentary and do not necessarily supersede one another', the individual evaluations of each technique are not changed to reflat the disposition of the tube.

f REVISION 0 PAGE 15 UL OUTAGE 11R EXAMINATION CATEGORIES AND RESULTS The location of the tubes and sleeves examined during Outage 11R are shown on Figures 111-1 through 111-4. The examinations were performed in three major groups, based on the examination requirement:
A.'
Examinations required by Technical Specification 4.19 or Generic Letter 95 03.
B.
GPUN elective exanunations The groups are further divided into specific categories. When classifying the tubes by examination category, some tubes may satisfy the criteria for more than one category and may need to be examined with more than one probe (in which case the tube will appear in more than one category). If the tube meets the criteria for multiple categories requiring examination with the same probe, the tube is placed into a category which gives precedence to the Technical Specification required examinations. Previously degraded tubes have the highest priority followed by Technical Specification required samples followed by GPUN elective exanunations. This section defines the examination scope, purpose, selection criteria, and examinations results by category.
. A.
SCOPE SELECTION During Outage 11R GPUN chose to initially perform bobbin coil exanunations on 21% of the total number of tubes in each OTSG. In order to define an examination results classification in accordance with Techmcal Specification 4.19 GPUN assigned tubes to techacal specification samples or other groups prior to the Outage. Sample expansion was then based on the results of each examination using Technical Srineation laterpretation 4.19 (Reference 1).
Tables III-l through III-4 provide the examination categories, quantities, probe size and reason for examination.

DEGRADED TUBE EXAMINATIONS DATA SETS: ISI,ISI-10R. ISI-UNSLV i
I TRENDING OF ID INDICATIONS i
To monitor for evidence of continuing degradatiun ofidentified indications, the 1995 11R exanunation results were compared to the 1993-10R exanunation results. The indications included in this comparison l
were previously recorded indications with through wall values of 16% or greater (see note on Table III-6) l l.
in both 1995-11R and 1993-10R. A siimmary and a complete listing of the indications are shown in Table III-5 and Appendix III respectively.
in OTSG-A.168 indications met the above criteria. The mean change in the indscations was +0.80% of +
l wall thickness between 10R and 11R (eenadard deviation 6.31% of wall). The amplitude of these l
indications showed a mean change of 0.30 volts (standard deviation 0.40 volts). During Outage llR a new calibration standard was introduced into the examination system to accommadate newer examination equipment. This standard affected voltage measurements when compared to the standard used during l
Outage 10R. The mean change in voltage, when using a voltage correction to compare Outages 10R to l
ilR more correctly is 0.15 volts. 'Ihe correction factor was established by incasunng the voltage differences between the old and new standard for ten different cal groups The conection factor for each cal group was determined by the formula (correction factor = old standard voltage /new standard voltage).
l The mean for these corrections was used to establish the correction factor to be used for statistical purposes A 1.41 volts correction factor (Outage !1R voltage x 1.41 = 11R corrected voltage) was applied l
for those indications affected.
In OTSG-B,29 indications met the criteria. The mean change in the indications was +1.72% of wall thickness between 10R and llR (standard deviation 6.80% of wall). The amplitude of these inviratians showed a mean change of-0.05 volts (standard deviation 0.19 volts). A new cahbration standard was also introduced into the examinarian system for OTSG-B also, but voltage comparisons between the new and old standards revealed that no corrections for data comparison were required.
When combined, the average change ger indication for both OTSGs was +0.93% of wall (ainadard deviation 6.39% of wall). The mean amplitude change was -0.26 volts (standard deviation 0.40 volts).
To determine the significance of these changes, the data was compared to similar evaluations performed during previous examinations. Based on this comparison (see Table III 6), in which the mean change has been both positive (apparent increase in the depth of the indications) and negative (apparent decrease in,
the depth of the indications), the identified changes are considered to be within the qualified repeatability of the ECT process, and do not indicate a trend of ongoing degradation. This variability is discussed in l
, Reference 6.

The results of the llR examinatian, of the " Degraded" tubes were consistent with previous examination t
results. The majority of the previously identi6ed indicanians showed no evidence of change from previous examinations. In three cases (oos in OTSG A and two in OTSG-B), the reported percent through wall values exceeded the established plugging criteria. All three tubes were removed from service by plugging.

l One (1) sleeved tube (66-1) had an inner diameter initiated indicanian of 43% through wall located 27.5 inches above the 4th support plate (outside the sleeved portion of the tube). The indication was noted as 37% through wall with a slightly larget voltage during Outage 10R so, in accordance with Technical i
Specification 4.19, is.not considered in the inspection results count of defective tubes for results i
categorization (less than 10% through wall growth). One tube (67 130) had a dent at the 15th support plate which was examined with MRPC and dispositioned as no detectable degradation. One tube had a less than 40 volt dent at the lower tubesheet. Indications identified during Outage 11R but not presiously recorded are detailed in Table III-7.

OTSG-B The 12% random sample of tube crapunations identified three degraded tubes due to tube to tube support plate wear. The 12% random sample of tube examinatians in OTSG B, also initially identified two defective tubes so this sample was categorized as C-2 per Technical Specification 4.19. The required actions required for a C-2 categori7mtian were completed (bounding tube examinations and plugging of defective tubes was completed). The initial 3%,6% and 12% samples complied with the sample requirements for a C-2 categornation except for bounding examinations. Boundmg examinations performed around one tube (46-117) identified one additional defective tube (45-118) which was counted towards the total count of defective tubes in the 12% sample per Technical Specification Interpretation 4.19 (Reference 1). Bounding examinations around tube 45-118 identified no newly degraded or defective tubes. Seventy-four tubes had recordsbic lower tubesheet dents with no evidecce of degradation. Twenty-seven of these dents were examined with MRPC and no degradation was detected. These twenty seven dents were comprised of all dents > 40 volts and an additional 18 dents less than 40 volts.

LANFJWEDGE EXAMINATIONS DATA SETS:
LANE / WEDGE, BORDER-SLV BES.ULTS The examinations identified no evidence of high cycle fatigue or precursors to high cycle fatigue. These examinations completed commitments in the GPUN response to Generic Letter 95-03 (Reference 3).
During examinations in both OTSGs very smallinside diameter initiated indications were identified with the MRPC examinations. These were single volumetric indications (not crack like) with sizes consistent with IGA identified duringprevious tube pull specimen analysis (Reference 14). Subsequent examinations with the.540" bobbin coil probe determined they were not of a significant nature, not crack i
like based on MRPC and because they were either not detectable or were classified as BVC indications (small amplitude indications with low signal to noise ratio). Tables III-16 and III 17 below detail the results of these examinations for OTSG-A and OTSG-B, respectively.

No degradation was identified in the tubes examined. These tubes were also examined full length with bobbin coil probes and no degradation was identified.
The shop manufacturing records are not clear on the exact location for some of these tubes so all insenice tubes where shop records indicated a reroll could likely exist were examined. One reroll was positively identified with both MRPC and bobbin coil tubesheet profile techniques. Two additional tubes exhibited MRPC data indicative of an additional rolling process.

DISCUSSION OF RESULTS
- 1. Inner Dinaa*ar Tube f adiraniane Since 1981, GPUN has characterized the location and distribution ofindications in the OTSGs by a bulk comparison of the recorded indications. This characterization includes both newly detected and preiously detected indications and is intended to confirm that the population of indications is stable and the condition of the OTSGs has not changed significantly since the previous examination. The data from the 1982 examinations is presented to show the contrast between the examination prior to and after the 1982 repairs See Figures III-5 to III-8.
The breakdown of the indications shows they are located towards the top of the tube bundle in Loth OTSG-A and OTSG-B. In OTSG-A, the indication rates are higher towards the periphery of the tube bundle, while in OTSG-B the distribution is more uniform.
A characterization of the size of the indications shows the relative amplitude continues to remain small, with 88 percent of the indications less than 2.0 volts. The indications continue to be part through wall with 260 of the 263 indications, which could be assigned through wall values, recorded as less than 40 percent through wall.
The circumferential extent was recorded with respect to the orientation of the indication. Of the 72 indications recorded with the MRPC probe, all were recorded as single volumetric (i.e. not
" crack like") indications (SVI) indicating there was no significant axial or circumferential extent.
During this outage bobbin coil erammations, in tubes not considered proiously degraded, identified 4 inside diameter indications in 4 tubes. A comparison of these indications to proiously identified indications shows they are consistent in both size d location to indications identified in other tubes..
During this outage, MRPC examinations were performed on the Lane / Wedge tubes instead of the previously used 8x! array probe. The MRPC probe uses a 0.115" diameter coil instead of a 0.187" diameter coil plus provides essentially 360 degree circumferential coverage with rnore
]
consistent sensitivity than the 8xl probe. The smaller coil design prmides a slightly improved j
response to very small indications. Improved uniform sensitivity increases the chance that very small indications will be detected. These two improvements significantly increase the probability
)
of detection of very small volumetric indications that were not proiously detected. During Outage 11R MRPC examinations of the Lane / Wedge and Sleeve Border tubes identified 34 SVI indications in 27 tubes. All of these indications were examined with a 0.540" bobbin coil probe and evaluated as no detectable degradation or BVC (less than 1 volt and less than 3 to 1 signal to noise ratio). Based on these factors and results from previous tube pulls, these werejudged to be a result of the 1981 sulfur intrusion and not an indication of a new or continuing degradation.
The reason for identification during Outage 11R is the result of the improved examination technique. This conclusion is further supported by the rate of occurrence in the OTSGs (OTSG-A has a higher rate of occurrence than OTSG-B).

- 2. WEAR INDICATIONS Eddy current examinations performed during Outage 11R identified 31 (18 in OTSG A and 13 in OTSG B) tubes with tube to tube support plate wear. During Outage 11R all bobbin mil distorted support plate indications were er=inad with the 3 coil MRPC examination technique. Support plate locations with confirmed indications, sutular to wear indications from pulled tubes at other OTSGs.
were sized using a voltage calibration curve from the MRPC probe. Outage 11R was the first outage in which this sizing technique was used at TMI 1. A bobbin mil through wall measurerrr.nt was.
l however, recorded where the signal permitted meanmgful measur==r The more consenative through wall measurement was used for determmmg repair requuements and classificat-of results (classifying the indication as an imperfection or degradation).
4 Exammations in OTSG-A identified three newly degraded tubes due to tube to tube support plate wear (no defective tubes due to wear). Exammations in GTSG-B identified two defective and six newly degraded tubes due to tube to tube support plate wear. Figure III-9 prmides a tubesheet plot of all wear indications recorded in OTSG A durmg Outage 11R and Figure III-10 prmides the same for OTSG B.
Review of the plots shows that the wear is generally limited to the lane / wedge or locations outside the tic-rods. No pattern of tubesheet location relative to support plate elevation muld be established.. Wear indications were identified at support plate tocations as low the 3rd support plate. Table HI 19 below prmides a breakdown of remrded wear indications by support plate elevation. Where more than one elevation exhibited wear, each elevation was counted as a location (two tubes in OTSG B had wear at threc locations and were remmed from senice).

0 Rmiew of the above table indicatesjust mer 25% of the total indications occur at the 14th support plate with no other elevations showing a concentration of any significance. Distnbution througlxnit the elesanons appears to be consistent in both OTSGs The mean through wall loss for these wear tubes, based on MRPC sizing results, in OTSG-A is 13.5%
and 17.5% in OTSG-B. A mean through wall loss for the bobbm coil techmque was not recorded because the majority of these wear indications remain classified as "DSI" signals without an assigned bobbin coil percent through wall (through wall measurement was assigned from the MRPC examination).
InAm'ian History and Growth Rate Eddy current data from prmicus outages was rmicwed to aid in quantifying a growth rate (due to the absence of prmious sizing data using the MRPC probe). Twenty of the 31 indications were evident in proious examinatmns datmg back to as early 1984. Of the eleven tubes not exhibiting prmious indications eight were prmiously exammed in 1984. Tius raiew rmeals a slow growth rate based on thelong cycle of existence.
i
.3. OTHER OUTSIDE DIAMETER INDICATIONS Bobbin coil examinations identified possible outer diameter indications (which were not confirmed as tube to tube support plate wear) in 22 tubes in OTSG-A and 21 tubes in OTSG-B.
These indications were evaluated in a very conservative manner and the subject locations were then examined with the MRPC probe unless comparisons indicated they were unchanged from Outage 10R and were evaluated as no detectable degradation at that time. All these indications were evaluated as no detectable degradation except for one tube (B120-42). Nonc resembled axial groove IGA as seen at another BWOG licensee plant.
Tube B120-42 was a previously degraded tube which was dispositioned as 35% T.W. at 004
+14.4" during Outage 10R. During Outage 11R this indication was dispositioned as 44% T.W.
with a confirmed single volumetric indication by MRPC examination. This tube was removed from service for this indication. Resiew of Outage 10R data showed no change in shape or amplitude for this indication.

- 4. DENTINGINDICATIONS During Outage 11R dents and dings greater than ten volts were recorded. All recorded dings (tube diameter reductions not attributable to a support structure) were examined with hmPC. All recorded dents above the lower tubesheet were examined with MRPC. At the lower tubesheet secondary face all recorded dents greater than forty volts were examined with MRPC while a sample of dents less than 40 volts were examined with MRPC. None of these MRPC examinations showed evidence of degradation. Table 11120 below details a summary of dent and ding quantities and MRPC examinations performed for both OTSGs.

DUE TO ADJACENT EXPLOSIVE PLUGS The LTS dents due to adjacent explosive plugs are generally midway between the primary and secondary faces of the LTS and are due to distortion of the tubesheet ligament resulting from installation of explosive plugs in adjacent tubes. These dents are small (generally 10 to 15 volts in ampl,itude) and have experienced over a decade of senice with no growth or degradation. The LTS dents at the secondary face are generally located in the OTSG " kidney-shaped" area which is generally an area oflight sludge buildup (2-3"). All of the recorded dings and dents passed a 0.510 bobbin coil probe. One LTS dent (tube B-56-74) did not pass the 0.520 MRPC probe and was examined with a 0.500 MRPC probe.
The Outage llR " Top of LTS Dents" MIZ-30 dent voltages were compared to previous examinations with MlZ-18 acquired data. (Previous data obtained with hEZ 12 instrumentation was excluded because of signal saturation. This exclusion involved all data acquired prior to 1988.) The mean change in voltage in OTSG A was +2.60 volts and in OTSG-B was +0.67 volts. In OTSG-A four dents increased in voltage and four dents decreased in voltage. In OTSG-B nine dents increased in voltage and seven decreased in voltage. The relatively small number of dents related to specific outages does not statistically support a voltage growth per cycle conclusion. The mean voltage change and the fact that all these dents passed a 0.510" bobbin coil probe qualitatively support a slow growth rate, if any.
An Outage 12R examination scope to continue to monitor diameter reductions will be established prior to the Outage.

CONCLUSIONS j
f
^
Based on the results of the 1995, Outage 11R, ECT exanunations and data evaluations, GPUN was able to reach the following conclusions:
4 1.
The examinations of the previously " Degraded Tubes" did not indicate a trend of ongoing degradation.
j 2.
The results of the 21% Technical Speci6 cation sample tubes did not reveal a trend of new damage mechanisms.
[
3.
Tube to tube support plate wear is occurring in relatively low numbers and growth rate j
is considered small based on previous existence. This mechanism will continue to be t
monitored.
4.
Tube denting at the secondary face of the lower tuhesheet. is occurring which is typical of '
j the OTSG kidney shaped sludge pile region. No evidence of cracking was present based l
on MRPC examinations. Continued monitoring of dented tubes will better define rate of 3
increase of diameter reduction and will indiente if cracking would begin to develop.
5.
The results of the " Gap Tube" sample indicate no degradation to the exposed carbon steel tubesheet.
l 6.
The results of the " LANE / WEDGE" and " BORDER /3LV' " erammations identified no presence of high cycle fatigue or cracking in the kinetic expansion transition area.
i 7.
The sleeve exammarians performed indicated that the installed sleeves continue to i
perform without degradation 8.
The examinations performed as comdiitments to Generic Letter 95-03 identified no j
circumferentialcracks
'9.
No freespan " Groove IGA" or axial cracking was identified.
10.
The MIZ-30 eddy current systeni performed equivalent to the MIZ-18A system.
