During Octcbor 1991, whilo TM1-1 was uhut-down for Hofueling. Outage 9R, GPUN performod Eddy Current (ECT) examinations of tho once Through Stoam Generators (OTSGs). The Lcope of tho examinations includod tubing, plugs and sloovos.

Tho tubing examinations woro required by Technical Specification 4.19 (Referenco 1), and CPUN ongincoring requirements.

During Outage 9R, a total of 1792 cxaminations woro performed on 1243 tubos in j

OTSG A and 1519 oxaminations woro performed on 966 tubos in OTSG D.

Based on thoso examinations, one tube in OTSG A and two tubes in OTSG D were removed from service by plugging.

This brings the total number of plugged tubos to 1268 in OTSG A and 372 in OTSG B.

This report was prepared to satisfy the reporting requirements of Technical _

specification 4.19,5.b (Reference 1)..The data was extracted from GPUN TDR 1068 (Referenco 10)

The Eddy Current (ECT) Examinations woro performed using the Zotoc M11-18, Digital Multi-Frequency Eddy Current System. The data was recorded on digital tapo and later coplod to optical discs for data analysis.

The examinations woro performed remotoly using D&W " ROGER" in-head fixturos and Zotoc Model 4D probo puchots.

During thin outago, "ROGTR" fixturos were installed in all four OTSG heads permitting the examinacion of plugs in both the uppor and lower tuboshoots and allowing the examination of tubing from either head.

This arrangement also.

permitted the examination of tubos from tho. lower head while tubo sleovos woro being installed in the upper head.

This is the first time ECT oxaminations have been dono from the lower head at TMI-1.

The ECT examinations utilized a variety of techniques and probos which wore tailored to the specific area being examined. The examinations woro performed under GPUN surveillanco procedure 1300-4B (Reference 5) and are discussed in the following section.

The specific probo models used aro. listed on Tablo II-1, l

Revision 0 page 5-A.1 Epy ral Tube Examinations The general examination of the tubing material is performed from the inside of the tubos using the bobbin coil probo, This prebo is the noct durable probe available and permits examining the tubos at speeds up to 24 inches por second.

The data from the bobbin coil probes is used for the detection of most types of degradation including ICA, ICSCC, tube to support plate wear and can also be used to measure tubo diameters and profilos.

In the case of tubes with no previous degradation, the examination is-performed using a.510" diamotor probe with an examination speed of 24 inchos por second.

For tubes with previous _ indications, the examination is performed using a.540" diameter probo at a speed of 12 inches per second,_ This.540" diameter probo is also used to disposition indications recorded as 30% through wall or greater using tho.510" dianctor probo.

Following the bobbin coil examinations, tubes with indications 40%

througn wall or greater are examined using an 8x1-ADS probo.

This probo has eight independent coils, referred to as pancake coils, which are especially suited for the detection of circumferentially oriented degradation.

The 8x1-ABS probe is less durable than the bobbin probo and also requires a slower speed of 6 inches por second during data acquisition.

The data from the 8x1-ABS probe is evaluated to confirm the relevancy of the bobbin coil indications and is also used to determino the circumferential extent of the degradction.

(Referenco 8)

The !inal disposition of the tubes is based on the eddy curront results (bobbin coil and 8x1-ABS), tho axial location of the degradation, and the location of the tube within the tubo bundle.

Tho eddy current input is based on the percent throuch wall as determined by the bobbin coil probe and the circumferential_ extent as determined by the 8x3-ABS probe.

1 A.2 Lano/Wedae Examinati2HE The tubes in_the lane / wedge region of the OTSGs are subject to high cycle f atigue f ailures at the 14";and 35" tube support plates and at the secondary face of the upper tube sheet. These failures occur very rapidly during OTSG operation and_the detection'of part through wall,-

high cycle fatigue is considered unlikely; however, the significance of a high cycle fatigue. failure warrants performing specialized examinations which are designed to detect-both high' cycle fatigue and-its precursors.

The fat. ares typically occur at the edges of_the support. structures _and--

are circumferentially oriented ~hich limits the sensitivity of the w

bobbin coil probe in this area. To overcome the limitations of the-bobbin coil probe, those arcas are examined using a pancake coil probe.

The coil orientation and surface riding design of the pancake coil probe improve.the sensitivity for detecting circumferential flaws and minimize 1068ATT1.TDR d'.

a e

4 Revision 0 Page 6 the negativo offects of the support structures or any denting which may be present.

At present, thoro are two basAc designs of pancake coil probes available for this examination, tho 8x1-ADS probe and the Motorigod Rotating Pancake Coil (MRPC) probo.

The 8x1-ADS probo has been used for.this examination sinco 1988-7R and was used for the majority of those examinations during Outage 1991-9R.

The 8x1-ADS probo has always been prona-to mechanical failure and has inheront limitations in the extent of coverago around the tube's circumferenco.

Those shortcomings have lod to an industry wide phane out of the Bx1-ABS probo and its replacement with the MRPC probo.

The MRPC probe is designed to be more durable than the 8x1-ADS probe, provides completo coverago of the tube's circumferenco and provides the best data analysis capabilitics of the available probos.

The MRPC probo's data acquisition process is more complex and slower than the 8x1-ABS probe (0.2"/sec versus 6"/soe) which requires a chango in the data acquisition motnods.

In recognition of this, the HRPC probe was used to examine about 40 lano/ wedge tubos in cach OTSG to determine the feasibility of replacing the 8x1-ADS probe with the MRPC probo.

A.3 Dimp,1.f111 red Tube Examinations During the conduct of examination using both the bobbin coil and Ux1-ABS probos, ambiguous indications aro detected and require further ovaluations.

Those indications are resolved by examining tho suspect area using tho MRPC probo and correlating the results of the various examinations to determine the disposition of the tubo.

A.4

'Lybe Slarve Exantinationi During Outage 9R, GPUN installed tube sleeves in 125 tubes in each OTSG, In support of the 81covo installation, eddy current examinations woro performed both prior to and after sloovo installation.

Sinco all of the tubes to be sleeved were part of the lano/ wedge region, no. additional examinations were required prior-to alcoving; however, additional data analysis was required.

The additional data analysis consisted of measuring the diamotor of the tube in the locations where the sleevo roll expansions are to be placed',

This process, referred to as " Bobbin-Profilometry" was performed using the data from tho.510" bobbin coil probe, Following the sleeve installation, tho.431 inch innor diameter sleeves were examined using a 400 inch diamotor combination bobbin coil and cross axis coil probo with a fill factor of 86%.

This probo.was used to examino both the parent tubing and the sleeve material for degradation.

In addition, the data was evaluated to measure the diamotor of the roll l

expansions-using the " Bobbin-Profilometry" process.

DATA _ ANALYSIS PROCESS The data emalysis process is baJed on the recommendations of the EPRI

/WR Steam Generator Inspection Guidelines (Reference 6).

The process included the use of written interpretation guidelines, which are filed with the examination data site specific training and testing and independent two party analysis of the data.

B1 Data Analyst oualifications The data analysis process was performed by a combination of B&W and Conam Huclear personnel qualified and certified to at least Level IIA, in accordance with their approved programs. As a supplement to this qualification, site specific indoctrination and training was attended by all data analyst personnel.

The program included both classroom Icetures and hands on practice using oddy current data and experience from both TMI and another B&W designed plant.

The training covered generic OTSG degradation mechanisms and examination methods and aleo specifically addressed both the Bobbin Coil and 8x1 Absolute methods which aro used at TMI.

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 the designated lead analyst.

At the completion of the indoctrination, each data analyst was required to pass a performance demonstration for each method to be analyzed. Appendix VI is an outline of the program.

B.2 Data Analysis Secuence The data analysis procons was performed in accordance with the same s

guidelines used for the data analyst indoctrination and training.

The process was performed-in three (3) parts with at least'two-(2)' separate-data analysts evaluating 100% of the data for each examination.

The only exception to this was the tube profilometry examinations, performed for tube sleeving, which received only a single analysis.

The data analysis process included:

1.

Primary Aanlygla:

The primary analysis-included a 100%

evaluation of the ECT data and the recording of all attributes identified in_ Appendix I.

_This analysis included recording the phase angle, percent through. wall, voltage,-

circumferential extent and' location of the indications.

2.

Sgpondarv Analysis: The secondary analysis also included a 100% review of the ECT_ data for the attributes identified in Appendix I.

This analysis, performed as a blind review, was performed in the same manner as the orimary analysis.

1068ATTI.TDR.

Attachm nt 1 Revision O' Page 8 3.

Ensolutl.on Analysis: To completo the analycia procese, the results of both the primary and secondary analyses are reviewed by the designated lead afinlyst.

This review combines the primary and secondary analyses results and niso resolves any discrepancies.

For Outago 1991-9R, this function was perforned by a Level III Data Analyst.

B.3 pata Analysis Software The dats from the tubing examinations was ovaluated using the Tetec Eddynet Analysis software, Version 2-Revision 1, for the primary, secondary and resolution anslysis.

The pre-sleeving and post-eleeving tubo diameter checks Woro evaluated using the Zetec DDA-4, Fevision 12, Tube Sheet Profilometry software.

D.4 ggcordina of Indications when analyzing the oddy current data, various indications are recorded by the data analyst.

These indications fall into two basic groupL,

" Indications from Tube Wall Degradation" and " Indications from Possible Damage Precursors". A complete list of all abbreviations and definitions used to classify indications is included as Appendix I.

Indications from Tube Wall Dearadation During the evaluation of the ECT data from bobbin coil examinations, indications of tube wall degradation are recorded by "porcent through wall" or by a throo letter code to indicato a probable flaw.

Indications which are recorded as 40% T.W. or greator, DNI, DSI, DRI, DTI or NQI are all re-examined using a pancake coil probo (8xl-ADS or MRPC).

The indication la then dispositioned based on the combined results of the two probes.

Indications which are from 20-39% through wall are. recorded for monitoring during future examinations.

In addition, a one volt recording threshold has been established'for inner diameter initiated indications.

Indications below this threshold are recorded as "BVC" and are monitored during subsequent examinations.

In the case of outor diameter-indications of less than one volt, a pancake coil examination is performed following the initial dotection of the ind! cation.

If the indication is determined to be acceptable based on the combined results of the bobbin coil and pancake coil examinations, the tube remains in service and can be monitored as a

'BVC", using the bobbin coil probe, during subsequent oxaminations.

1068ATT1.TDR

,.__-..u_

L Revision 0 Page 9 Indications from Possible Damaae Recursors l

The analysis of the eddy current data also identifica indications which are not attributed to tube wall degradation.

These indications may be i

the results of irregularitics in-the tube wall profilo (IDC), changes in the magnetic permeability (PVH), denting (DNT) or other changes not related to tube wall degradation. These indications are recorded ~for information only and do not require follow-up examinations.

Indications Recorded durina Snocialized Examinations The data analysis for specialized examinations such as 8x1-ABS or MRPC probos requires a process which is different-than the bobbin coil examinatione.

In the case of these examinations, the data is typically.

ovaluated to confirm a previously recorded indication.

As such, the data is recorded to support dispositioning a given indication by length, size, depth or location on a case by case basis.

Indication Locations:

The locations of the ECT indications are recorded to identify their "olevation* or ' axial location" in tho OTSGs.

_For-free span indications the locations are recorded in inchos above "+' the tuboshoo; surfaces or tube support plato center.

For-indications located within or adjacent to the tube support plates, the indications are recorded as *+" or * " from the center of the T.S.P.

The.relativo locations of the tubesheets and tubo support plates (T.S.P.) are shown in Figuro II-1.

The locations of the tubes and plugs examined during Outago 9R are shown on Figures III-1 through III-4.

The examinations were performed in two major groups, based on the examination requirement.

A.

Examinations Roquired by Technical Specification 4.19 D.

GPUN Electivo Examinations These groups aro further divided into specific categories of tubes.

This section definos the examination scopo, purpose and examination results by category. When classifying the tubes by examination category, some tubos may satisfy the criteria for more than one category and may need to be examined with more than one probe.

In those cases, the tube is placed into the first category which applies following the sequence of this report.

As a result of this sequence, some tubes may appear to be missing from a catoe,ary because they were previously examined.

For examsdo, a lano/ wedge tube may.have been examined as r

'SI tube and will not be re-examined as a lano/ wedge tubo.

EXAMINATIONS _BEOUIRED BY TECHNICAL SPECIFICATION 4ill A-1 PREVIOUSLY DEGRADED TUDES Data Sets:

ISI, ISI-8R Probo:

.540" - Bobbin Ext =at:

Full Length SCOPE In OTSG "A", 286 tubes were examined.

In OTSG "B", 39 tubes were examined.

REASON FOR EXAMINATION The examination of the "Dograded" tubes serves a dual purpose.

First, new examination results are compared to the results of previous examinations to determine if there is evidence of an active degradation mechanism occurring in the OTSGs.

Second, the examination provides assurance that no tubes with indications exceeding the plugging criteria remain in service.

Revision 0 pago 13

,gCTION CRIT.EElh The 'Dograded Tube

incorvice tubos which have previously identified tube wall degradation of 20%

T.W. or greator.

During the period of loS1 to 1988-7R, tubos were scrooned with the bobbin coil probo nd all indications woro then oxamined using the 8x1-ADS probo.

Tubos with. dications a20% T.W. which woro confirmed by the ax1-ADS probo were then cor::dorod to be degradod and woro included in this population. Those tubos a identified as the sub group of *ISI".

one of the inhoront limitations of tho 8x1-ADS probe is the variability of the oddy current field based on the coil to discontinuity orientation.

This variability is most pronounced for small discontinuities and using tho above=

method, tubos with small indications tended to drop in and out of the "Dograded ';ubo" population.

To reduce this variability, starting with the 1990-8R examinations, all insarvice tubos with bobbin coil indications of 20-39% through wall are included in this category.

RCSULTS The results of the 9R exmainations of the "Dograded* tubos. wore consistent with previous examination results.

The majority of the previously identified indications showed no evidence of change from previous examinations, In two j

casos however, the reported t through wall values excooded tho.catablished plutging critoria and the tubos wero-romoved from service.

OTSG A ono (1) tubo (A-95-126) had an indication of >40% through wall in the froospan portion of the tubo and was removed from service by plugging.- The indicatien in this tubo was 1-coll in circumferential extent.

CTSG D Ono (1) tubo (D-24-63) had an indication of >40% through wall in the freospan portion of the tuba and was removed from service by plugging.

The indication in this tube was 1-coil in circumferential extent.

To monitor for evidence of continulug dogradation of identified indications, t,1 1991*9R oxamination results woro compared to the 1990-8R results. =The indications included in this comparison were previously recorded indications with through wall values of 16% lor greator in both 1991-9R and 1990-8R.

The breakdown o' the indications is shown in Table 1 and Appendix II.-

In "A" OTSG, 190 indications mot the above critoria.

The mean chango in the indications was -2.2% of wall thickness betwoon 8R and 9R (standard deviation 7.28% of wall).

The average change in the indications was -0.8% of wa?1 thickness between BR and 9R (standard deviation 5.02% of wall).

The amplitude of those indicatione showed a mean change of

-0.01 volta (standard deviation 0.07 volts).

When combined, the averago chant,, por indication for both OTSGw was -2.0% of wall (standard deviation 6.96% of wall). The mean amplitude change was 0.07 volts (standard deviation 0.31 volts).

To determino the significance of those changes, the data was compared to similar ovaluations performed during previous examinations.

Dased on this comparison (see Table 2) in which the mean chane,e has been both positivo (apparent increase in the depth of the indicatAons) and negative (apparent decrease in the depth of the indications), ths identified changes are considered to be within the qualified repeattbility of the CCT process, and do not indicato a trend of ongoing degradation This variability is discussed in Reference 3.

FVASGN FOR EXAtilNATION The tubci. in this sample have no history of degradation below the kinetic expansion, They are examined to monitor the overall condition of the steam genetator tubing.

%$CTION CRITERIA nitial sample included at least 3% of all the tubes in each OTSG.

As ved by *.S.

4.19.2.a.2, at least 50% of the tubes were located in the m.

perip.e ar of the OTSG which is an area where experience has indicated cial problems.

(The outer periphery is defined as the tubes located

.s

e the radius of the outer support rods).

The remaining tubes wero eted to provido a representative sample of the tube bundle.

As directed by Engineering, the samples were selected to include tubes which have not been examined since the 1984 examinations (65%) and tubes which had bef. examined since 1984 (35%).

ECB]lV20 QISG A In OTSG A, the examination of the 3% T.S.

samplo revealed indications exceeding 20% through wall in two 'ubes (A-1-14 and A-49-110).

The indications in both of theta cubos woro recorded as 23% through wall and the tubos will be added to the degraded tube population of the next examination, QTSC D In OTSG B, the examination of the 3% samplo did not reveal any indicat. tons exceeding 20% through wall. One tube (B-121-7) had a small amplitude I.D.

BEASQN,_IOR EXN11 NATION O

This tube was examined to continue monitoring the status of the previously recorded indications.

EFU CTION CRITERIA Since 1981, GPUN has used a two step process to identify and disposition indications.

In this precess, indications are screened using ths bobbin coil probe and are confirmed usi ug the Ex1-ABS probe.

Indications which are screened by the bobbin probe but are not confirmed by the 8x1-ABS probe are considered to be either relevant indications which are below the required threshold of detection or non-relavant indications caused by something other than tube wall degredatian.

The tubes with these indications are placed in this category until additional data becomes available and the tubes are either repaired, moved to other categories or returned to the general tube population.

This tube has an indication which appears as 40% through wall or greater using the borbin coil probe, but appears to be non-relevant using the 8x1-ABS probe.

In the future, only tubes with indications which appear 240% through wall by bobbin probe, but are determined to be tci-relevant by other orober,, will be included in this category.

Tubes with indications <40% through wall will be examined as "ISI" tubes.

RESULTS OTSG A In OTSG A, the indication being monitored in tube A-36 103 continues to appear as a non-relevant indication based on the 8xl-ABS probe. This tube will be monitored during the next examination.

OTSG B There are no tubes in this ca.cgory in OTSG B.

In-consideration of possible accelerated degradation in this area, GPUN clected to examine all of-the lane / wedge tubes in accordance with Paragraph 4.19.2.a.4(1) of the TMI-1 Technical Specifications (Reference 1).

In addition to the regular flaw analysis, the bobbin coil data from the "SLEEVEBASE" data set was also-analyzed to metsure the tubo diameters in support of the sleeve installation task.

The 8x1-ABS'and hRPC examinations were performed to examine.the tubing at the-14* and 15" tube support plates and at the f ace of the upper tubesheet. The examinatient1were originally scheduled to be performed from the upper head q

using the 8x1-ABS probot however, the tubes located under the indexing fixture-

=

were cy'imined from the lower head using the MRPCiprobe, The MRPC~ probe is considered equivalent to-the'8x1-ABS probe and was used to compare the-'apeed' and durability of using the MRPC probe in place of the Bx1-ABS probe.

ELECTION CRITERIA This examination included all incorvice tubes in the Lane and Wedge area

Revision 01 Pace-20 BESULTS OTsc A-In OTSO A, the defect analysis identified a 37% through wall indication in one tube (A-66-1).

This tube had previously been examined as an ISI tube (Section A-1); therefo:0, no additional action was required.

In addition, two other tubes (A-74-23 and A-75-26) had indications (BVC and DST) recorded.. Normally these indications would require follow-up examinations; however, since both indications were repaired through the normally planned sleeving, no additional actions were taken, i

The evaluation of the tube diameters for the "SLEEVEBASE" tubes revealed no unacceptable conditions and the data was turned over to the Sleeving Task l

Manager.

l OTSG B In OTsG B, suspected tube wall degradation was identified in four'of the tubes. This degradation included tube support plate to tube wear in two tubes (B-75-2 and B-75-4).

The wear in tube B-75-2 was located at the 4",

5",

and 6" tube support plates and, based on follow-up MRPC examinations, was L

determined to have a maximum depth of 28% through wall at the 5" tube support plate.

Since this area could not bo repeired by existing sleeving methods, the tube was preventively plugged.

In tube B-75-4, the wear w(s located at the 15" tube support plate and based on the MRPC, the wear was determined to be 37%-through wall. This tube was sleeved as part of the original sleeving scope, which repaired this area of the tube.

One tube (B-75-23) had a-distorted tubesheet indication reported at tne face of the upper tube sheet.

This indication was not confirmed by either the 8x1-ABS or MRPC probes and the tube was preventively sleeved as part of the original sleeving scope.

The fourth tube with an indication was tube D-74-43.

This tube had a 1-coil 8x1-ABS indication ' recorded at the 15" tube support plate.

This indication was not confirmed by the MRPC probe; however,.the suspect area was preventively l

sleeved.

The evaluation of the profilometry data for the "SLEEVEDASE" tubes and tube B-l 74-43 revealed no unacceptable conditions and the data was turned over'to.the L

Sleeving Task Manager.

COMPARISON OF 8x1-ABS AND MRPC L

The comparison of the 8x1-ABS and MRPC prutes indicated the overall exami.ation speed was the same for both probes. The 8x1-ABS required-a longer set-up time with a faster examination rate than the MRPC.

The tube sample size was not large enough to evaluate the probe durability.

B-4 TUBES WITH PREVIOUS SHALL AMPLITUDE INDICATIONS Data Set:

S/N-OLD, S/N, Probe:

.540" Bobbin,.510" Dobbin Extentt-Full iength SCOPE In OTSG

'A", 71 tubes were examined.

In OT3G "B",

26 tubes wc;c examined.

REASON FOR EXAMINATION These the tubes were examined to verify the minor nature of the indications.

SELECTION CRITERIA During OTSG examinations performed during 1986-5M through 1990-8R, poor._ signal to noise ratio (S/N) indications of less than 1.0 volt have-been detected and evaluated using the bobbin coil probe.

During the examinations performed in outages 1986-SM, 1986-6R and 1988-7R, these S/N indications were also examined using the 8x1-ABS probe and any tubes with indications confirmed by the-8x1-ABS probe were re-examined during the subsequent outage.

Those tubes with indications not confirmed by the 8x1-ABS probe were returned to the general sample.

Starting with the 1990-8R outage and continuing this outage (1991-9R), GPUN no longer.uses-the 8x1-ABS probe to confirm these less than 1.0 volt indications.

Instead, all less than 1.0 vo.it indications, with phase angles of;6' to 110*

and a signal to noise ratio of less than 3:1, are recorded as "BVC" (Below Voltage Critoria) for monitoring'during future-examinations.

These indications are considered relevant indications; however, the amplitude and signal to. noise ratio prevents assigning an accurate through wall depth, The inclusion of all indications, whether or not they were confirmed by the ax1-ABS probe, is intended to improve the repeatability of the examination process by eliminating the variabllity in the discontinuity to' coil orientation, which is an-inherent limitation of the 8x1-ABS probe.

This variability is significantly less of a factor with the bobbin probe thereby improving-the repeatability of the examination.

JAs=a result of the above changes, the data set of tubes-called S/N-OLD was

. examined in: addition to the S/N' data set.

The S/N-OLD data set contains-tubes with previously recorded S/N indicationsi which have;not been confirmed byithe+

8x1-ABS probe, and have not been monitored during subsequent outages. -With the inclusion of this data set,.all tubes with previouslyLrecorded indications, which-are considered relevant based on the signal-amplitude-and phase angle, were scheduled for examinations.

1068ATTI.TDR-

Attachmsnt 1 Revision 0 Page 23 BESULTS OTSG A The indications in 25 of the 71 tubes continued to appear as relevant indications but are below the threshold for evaluating the percent through wall depth and the indications were recorded as "BVC" (Delow Voltage Critoria). The indications in these 25 tubes will centinue to be-roonitored during the next examination.

In 16 of the 71 tubes, the-indications were outside the recording criteria, but, the tubes will be re-examined during the next outage based on the 1988-7R or 1990-BR examination results.

In the 30 remaining tubes, the indications are outside the recording criteria for relevant indications and no indications have been recorded since 1986-6R.

OTSG B In 15 of the 36 tubes, the indications were recorded as "BVC" and will be-monitored during the next examination. The indicatione in 5 of the 36 tubes were outsido the recording critoria but will be monitored during the next examination based on the 1988-7R or 1990-8R examination results.

In the remaining 16 tubes, the indications are outside the recording criteria for relevant indications, and no indications have been recorded since 1986-6R.

7 tubes were examined.

In OTSG "B",

6 tubes were examined.

RJASON FOR EXAMINATION These tubes were examined to confirm there are no relevant indications of 20%

through wall or greater.

SELECTION CRITERIA During previous examinations, indications have been detected and evaluated, using the bobbin coil probe, and determined to be 20% through wall or greater.

Subsequent 8x1-ABS examinations have not confirmed the indications and, therefore, they are considered to be non-relevant indications.

Since the indications were not confirmed by 8x1-ABS, only those indications which measured 40% through wall or greater were monitored as 8x1-ACC tubes during subsequent outages.

Experience has shown, however, that the variability of the 8x1-ABS probe may change the disposition of these tubes from outage to outage. To reduce this variability, all tubes with previously identified indications, evaluated as 20%-39% through wall or greater using the bobbin coil prole, were re-examined during this outage, RESULTS 2

OTSG A In OTSG A, one of the seven tubes had an indicatjon evaluated as 20%-39%

through wa11.

This tube, A-126-1, sill be considered a degraded tube during the next outage. One tube, A-90-118, had an indication of 40% through wall or greater recorded during outage 1988-7R.

This indication has been outside the recording criteria for relevant indications in both outage 1990-8R and 1991-9R, therefore, the tube will be examined ab an 8x1-ACC tube during the next outage.

In three tubes (A-99-62, A-132-7 and A-136-29), the previously recorded indications have been outsids the recording criteria in both outages 1990-8R and 1991-9R.

These tubes will also be re-examined during outage 10R.

In the two remaining tubes, (A-119-94 and A-106-69), the previously recorded indications have been outside the recording criteria for relevant indications for three consecutive examinations.

In OTSG "B",

1 tube was examined.

REASON FOR EXAMIN7sTIOU During Outage 8R, distorted tube support plate (DSS) or distorted tubesheet (DTI) indications were recorded during the bobbin coil examinations. The suspect areas were then examined using an 8x1-ABS probe and the indications were dispositioned as either being flaws or non-relevant indications.

Indications which were determined to be non-relevant are monitored during the next examination.

SILECTION ORITERIA All inservice tubes which had DSS or DTS indications recorded during outage 1990-8R were re-examined during 1991-9R.

BESULTS 9159 h In OTSG A, the distorted support plate signal (7" ar.d 8" T.S.P. ) in three of the tubes are no longer distorted.

This would indicate the probable cause of the distortions was foreign material or deposits on the tube support plate.

The remaining tube (A-150-24) continues to show a distortion at the 10" T.S.P.

The distortion does not appear " defect like" and has not changed since the last outage, so no further actions were taken.

The tube will be re-examined during the next scheduled examination.

OTSG B In OTSG E, the distorted support plate signal (12" T.S.P. ) in tube B-113-114 continues to appear questionable.

This support was examined using the MPPC probe and no degradation was noted.

DISCUSSION OF RESULTS Characterization of Indications The indications reported during 1991-9R were characterized by location, percent through wall, amplitude, and circumferential extent.

(Sco Figures III-5 through III-8).

This charactorization showed that the.

majority of indications are inner diameter initiated and are located.

towards the top of the OTSGs.

In OTSG A, the'irdication rates are higher

= 1 towards the outer periphery while the distribution is more uniform across OTSG D.

This is the same distribution of indications as identified-during the previous examinations.

The amplitudes (voltage) of the 1990-8R indications.were typically small,-

' l

<2.0 volts; The characterization by percent through wall shows most of-the indications are pa).ial through wall with 98.49, of the indications-

- i recorded as <40% through wall.

The circumferential extent of the 1990-8R-indications was 1 coil for all indications ercept two 2-coil indications.

This characterization in consistent with previous. examination-results.-

In' addition to the inner diameter indications, _ two types ef outer diameter indications were also detected.

In OTSG B, two lanc-tubes (B-75-2 and B-75-4) had indications of tube to tube support plate wear.

These wear indications spanned the entire 1-1/2" thickness of the tube support plate,_and, based on the MRPC probe, are the width of a single broached support plate land.

This wear is typical of wear identified'in other OTSGs and is similar to the wear identified in-_OTSG B during outage 7R, These two tubes were-repaired by the installation of-alloy-690 tube sleeves.

The second_ type"of outer diameter indication-is a[ discrete, small amplitude indication which appears at.a_ tube support plates During this outage a total of seven of'these indications _were recorded-.four-in OTSG A and three in OTSG B.

These indications were' recorded-in' tubes in the-degraded tube populations and in the lane / wedge. tubes.

No indications of this type were recorded in'the 3%-T.S. samples.

In OTSG.B, the three tubes were examined using the MRPC probe to evaluatof the indications.

In one tube (B-82-14), the indication was confirmed as a small rounded indication of about 22% T.W.

at-:the 6" tube support

- plate. In the other two tubes, (B-113-114, B-144-49), no indications; were detected by the MRPC technique.

In OTSG A, the indications were covered by tube-sleeves in two tubes, (A-75-17, A-75-26), therefore no--

additional examinations were performed. :In one of the tubes, (A-70-1),-_-

the-suspect area was examined using the 8x1 probe and-the indication was not confirmed.

In the fourth tube"(A-105-94), the subject-indication has.

~

- been_ monitored since 1984_and.has not shown any change during the seven examinations; therefore, no additional examinations were performed.-

.Pajo 30-r Egy,few of Previous Data j

f

'The ECT-examination' process-included a review of the ECT data from previous outages.

This review was performed to better' characterize and understand apparent changes in the ECT results from previous outages, j

J 1.

Tubes with Inner Diameter Indications

-l I

The previous examination data was reviewed for a total of three tubes with ihner diameter indications. These_ tubes were all ISI

'l tubes which were evaluated as being 240%.through wall during the 9R examinations.

In alli cases, the indications showed no apparent change from the last examinati7n and the change in'the o

assigned percent through wall is attributed to the variability-of the ECT process.

2.

Tubes with Outer Diameter Indications The previous examination data was reviewed for a total of three tubes with outer' diameter (O.D.) initiated indications.

These included one tube (B-82-14) which had a discrete O.D. indication at the 6" tube support plate. This indication-was essentially unchanged from the last examination-(8R)=. No additional' action is required for this tube.

The other two tubes (B-75-2 and B-75-4; had tube to tube support' plate wear. A review of_the past data shows the indications'had~

been present but not recorded during:the previous examination (8R),

Since the-wear-indications span =the entire _ length of the-tube support _ plate, the eddy current' signals tend to'look more' like a rotated tube support plate than a flaw.

The detection of these indications during-outage 19Riis attributed to improvements in.the_ analysis software and to increased analyst awareness for support plate indications.

During this examination, any' questionable indications at support

. plates were' examined using~the KRPC_ probe.

Using this_ approach, the wear-indications can be readily screened with the bobbin probe and-characterized with the MRPC probe. This processLwill~

be continued during future examinations and additional emphasis will be placed on vear indications.during the analyst's F

indoctrination.

CONCLbSIONS Based on the results of the 1941, Outage 9R, ECT examinations and data evaluations, GPUN was able to reach the following conclusions:

1.

The examinations of the previously " Degraded Tubes" did not indicate a trend of ongoing degradation.

2.

The examination results of the Tech. Spec. random samples'did not reveal a trend of new or continuing damage mechanisme.

3 The examination of the lane / wedge region indicates tube to tube support plate wear is occurring in isolated cases.

The current techniques are capable of detecting this wear; however, additional emphasis needs to be placed on this damage mechanism during the analysis procese.
