LO I~IDODO TIOD

The following is a summary report of the results of the multifrequency eddy

current examination performed during the 1995 Annual Refueling and

Maintenance Outage at the R. E. Ginna Nuclear Power Station in Ontario,

New York. The examinations were performed in both the "A" and "B"

recirculating steam generators which are Westinghouse Series-44 design.

Each generator contains 3260 Inconel 600 MillAnnealed U-Bend tubes having

an outside diameter of 0.875" and a nominal wall thickness of 0.050".

The purpose of the eddy current examination was to assess any corrosion or

mechanical damage that may have occurred during the cycle since the 1994

examination. Particular attention was given to the detection of:

1) Intergranular attack (IGA)and intergranular stress corrosion cracking

(IGSCC) within the inlet tubesheet crevice region.

2)

3)

Intergranular attack (IGA)and intergranular stress corrosion cracking

(IGSCC) within the outlet tubesheet crevice region (none detected).

Primary water stress corrosion cracking (PWSCC) at the inlet "

tubesheet roll transition.

4) Primary water stress corrosion cracking (PWSCC) at the outlet

tubesheet roll transition (none detected).

5) Pitting and wastage between the tubesheet and first support plate.

6) Wear at the antivibration bar to tube intersections in the U-bend

region.

7) Denting at tube support intersections.

8) Primary water stress corrosion cracking (PWSCC) in the Row 1 and

Row 2 V-bend area (none detected).

9) Intergranular attack (IGA)and intergranularstress corrosion cracking

(IGSCC) at hot leg support plate intersections (none detected).

The examination was performed by personnel from Rochester Gas and

Electric (RG&E) and ABB-Combustion Engineering (ABB-CE). All

personnel were trained and qualified in the eddy current examination method

and have been certified to a minimum of Level I for data acquisition and

Level H for data analysis. All examination activities were performed in

accordance with MEIS NDE-500-17. In addition, all acquisition personnel

were trained and qualified to site specific procedures and all analysis

personnel were trained and qualified to the site specific "Steam Generator

Data Analysis Guidelines - RG&E Ginna Station". These analysis guidelines

were prepared in accordance with Revision 3 of the Electric Power Research

Institutes (EPRI) "PWR Steam Generator Inspection Guidelines".

The data analysis was performed by two independent teams. For bobbin

data evaluation, the primary analysis was performed manually utilizing the

2 of 66

Zetec EDDYNET Data Analysis System and the secondary analysis was,

performed utilizing the Computer Data Screening (CDS) capability of the

EDDYNET system. Primary and secondary analysis of all other data (i.e.,

MRPC, Rotating Crosswound, Plus-Point, etc.) was performed. manually

utilizing the EDDYNET Data Analysis System. The results of all primary

and secondary analyses were compared for discrepancies using the

EDDYNET compare program. The typical data flow chart is shown on

Figure 1 (Page 5). The following list describes some typical discrepancies

between analysis teams requiring resolution by the Level IIIresolvers.

Any indication that is reported as >20% by either analyst and is not

reported by the other or is sized at >10% difference.

Any indication spanning the repair limit, (39% vs. 41%).

Any difference of > 1 inch in the axial location of a flaw.

Any tube which was analyzed by one analyst but not the other (may

have been missed or improperly entered by one analyst).

Any difference in the reported test extent.

o All indications identified as IGA and/or SCC regardless of whether

one or both parties have reported it.

Any tube reported as restricted by one analyst but not the other (may

have been missed or improperly entered by one analyst).

o Any tube for which a retest was requested by one analyst but not the

other.

o All Roll Transition Indications reported by one analyst but not the

other.

In addition to the above, gll tubes requiring repair whether reported by one

or both analysts were reviewed by the resolvers. In all cases, the removal of

a repairable indication from the data base received the concurrence of two

'Lead Analyst personnel.

2.0 DATA A SITI N PR RAM

The initial eddy current examination of the "A" and "B" steam generators

was performed utilizing a standard bobbin coil technique with data

acquisition being performed with the EDDYNET Acquisition System. The "

frequencies selected were 400, 200, 100 and 25 kHz. The examination was

performed primarily from the 1st tube support through the tubesheet region

to examine open crevice, roll transition regions, and the area between the

top of the inlet tubesheet to the 1st tube support plate. 20% of all open

tubes were also examined throughout the full length of tubing.

Additional eddy current examinations of the "A" and "B" steam generators

were performed utilizing the Zetec 3-coil Motorized Rotating Pancake Coil

(MRPC) probe to examine the roll transition region, and selected crevices.

The frequencies used for these examinations were 400, 300, 100, and 25

kHz. All row 1 and 2 U-bends were also examined with MRPC. Allsleeve

examinations (except for the B&W brazed and old style explosive sleeves)

were performed using the Zetec "Plus-Point" probe. The B&W brazed

sleeves and the old style explosive sleeves were examined using a saturation

bobbin technique due to the magnetic permeability of the sleeve material.

Prior to examination of the steam generators, an inspection program was

established for the inlet and outlet sides of both the "A" and "B" steam

generators. The inlet or hot leg examination program plan was generated to

provide the examination of 100% of each, open unsleeved steam generator

tube from the tube end through the. first tube support plate, along with 20%r

of these tubes being selected and examined for their full length (20% random

sample as recommended in the Electric Power Research Institute (EPRI)

guidelines) with the bobbin coil. In addition, 20% of each type of sleeve was

examined'and the remaining tube examined full length. All Row 1 and

Row 2 U-bend regions were examined with the Motorized Rotating Pancake

Coil (MRPC) between the 06H and 06C from the cold leg side.

A number ofsupplemental examinations were also performed to assist in flaw

characterization and confirmation and to continue to monitor for the onset

of new damage mechanisms.

Tables 1-A and 1-B are breakdowns, by steam generator, of all tubes

programmed for, examination, numbers examined and the extent examined.

3.0 DATA ANALYSISR TS UIVIMARY

The data analysis was performed using the Zetec EDDYNET System

(Version 27).

For the MRPC examinations, all data was reviewed by displaying the

400 kHz or 300 kHz pancake coil data in the lissajous dsiplay along with the

vertical component of the pancake and axial sensitive coils in strip chart

form. Other frequencies and coils were selected as necessary for the

evaluation of indications. No depth sizing was performed with the MRPC'ata.Any tube containing a fiaw detected by the MRPC examination was

repaired.

For the bobbin coil examination,'ll data was reviewed by displaying the 400

kHz in the lissajous display along with the vertical component of the

differential and absolute mix outputs in strip chart form (where applicable).

Other frequencies and their components were selected as necessary for the

evaluation of indications.

All recordable indications were logged into the computer and stored on

optical disk. The final report form summarizing all indications ) 20% TW

(including IGA and PWSCC which is assumed to be >20%) for each

generator can be found in Tables 2-A and 2-B. An explanation of the

abbreviations and nomenclature used on these lists has been compiled. for

ease of interpretation.

N'he

results of the examination indicate that IGA and IGSCC continue to be

active within the tubesheet crevice region on the inlet side of'each steam

generator. As in the past, IGA/SCC is much more prevalent in the "B" steam

generator with 80 new crevice indications reported. In the "A" steam

generator, 35 new crevice indications were reported,

The majority of the inlet tubesheet crevice corrosion indications are IGA/SCCI

'I

of the Mill Annealed Inconel 600 tube material. This form of corrosion is

believed to be the result of an alkaline environment forming in the tubesheet

crevices. This environment has developed over the years as deposits and active

species such as sodium and phosphate, have reacted, changing a neutral or

inhibited crevice into the aggressive environment that presently exists. Table

3 shows the steam generator IGA/SCC history.

Along with IGA/SCC in the crevices, there appears to have been a slight

decrease in PWSCC at the roll transition during the last operating cycle. This

mechanism was first addressed in 1989 and this year there were 32 Roll

Transition (PWSCC) indications in "B" steam generator and 60 Roll

Transition (PWSCC) indications in "A" steam generator. These numbers

include tubes that may have PWSCC in combination with IGA or SCC in the „

crevice.

A large volume, typically (20% TW, wastage type condition exists just above

the tubesheet secondary face of both generators. A small percentage of theI

tubes, generally toward the center of the bundle, have this condition. A

number of these tubes did have penetrations )20% TW but have not shown

an increase in the growth rate for several cycles. It is believed that th'ese

wastage indications were caused by the original water chemistry when

phosphate was used as a buffering medium.

Small indications of probable copper deposits were also found in the tubesheet

crevice region randomly located throughout each steam generator.

Minor denting has been detected at the tubesheet secondary face for many

years in both steam generators, primarily on the inlet side. Denting was also

detected at the 1st, 2nd and 6th tube support plates randomly throughout the

Page 42 of 66

generator, and in most cases was of greater magnitude in size than that at the

tubesheet secondary side face. In general, minor distortions of most of the

tube support signals were seen.

The denting phenomenon and minor distortions at the tubesheet and support

plates can be attributed to secondary'ide corrosion product buildup in the

annular region between the tube outside surface and the carbon steel support

member. Comparison with previous data indicates no changes in the denting

have been observed since previous inspections.

Eleven (11) indications in the CE welded sleeves (1 in S/G "A" and 10 in S/G

"B") were reported as a consequence of the use of the Zetec, Inc. "Plus-Point"

probe. This probe provides improved resolution characteristics which enable

the data analysis personnel. the capability of readily determining the existence

of degradation in either the parent tube or the sleeve. The indications in

question resembled blowhole type indications which had been previously

reported at Zion during early 1995. Subsequent visual examination of the

indications verified two (2) blowholes, one of which (the indication in S/G "A")

was left in service due to the fact that it was located in the upper region of the

weld. Eight (8) of the remaining indications in S/G "B" were determined to

be a result of "weld tail-off" when examined visually. The indication in Row

34, Column 40 was found to be a result of an "arc strike" and an incomplete

Page 43 of 66

weld in the upper expansion zone. (Subsequent review of the "Plus-Point"

)eddy current data confirmed the absence of a heat affected zone). As a result

of the discovery of the incomplete weld in Row 34, Column 40, additional

visual and ultrasonic examinations were performed on an expanded sample of

CE welded sleeves. One (1) additional sleeve (Row 41, Col 42) was found with

an incomplete weld and six (6) sleeves were determined by ultrasonics to

contain welds with incomplete fusion. The result of the expanded inspections

was that a total of ten (10) CE welded sleeves were plugged. In addition, two

(2) B&W brazed sleeves were repored with PWSCC indications at the lower

joint and one (1) BLW brazed sleeve was found to be without a braze in the

upper joint.

In summary, the "A" Steam Generator had 88.tubes that were found to have

"new" tubesheet crevice'indications (60 PWSCC, 35 IGA/SCC, 7 both

IGA/SCC and PWSCC). The "B" Steam Generator had 106 "new" tubesheet

crevice indications (32 PWSCC, 80 IGA/SCC, 6 both IGA/SCC and PWSCC).

Additionally 14 sleeved tubes were plugged (3 obstructed, 2 with PWSCC, 1

"blowhole", 2 unwelded and 6 unfused), accounting for a total of 120 repairs

in the "B" Steam Generator.

A Non-Conformance Report (NCR) was written on the ABB-CE.sleeves

containing incomplete welds or incomplete fusion and a 10CFR50.59 Safety

Page 44 of 66

Evaluation was performed. This evaluation coupled with structural analysis

and mechanical testing data provided by ABB-CE determined that the absence

of a complete weld or complete fusion in the subject sleeves did not constitute

a substantial safety hazard and did not require reporting pursuant to

10CFR50.72. Additional information regarding this condition is contained in

NCR's 95-029 dated 4/15/95.

Table 4 has been generated to identify tubes with crevice indications or with

indications which exceed the repair criteria. This table also shows the axial

location of the indication and what corrective action was taken on these tubes.

Tubes requiring repair due to hot leg tubesheet crevice indications were

identified by the appropriate codes:

a) quantifiable and non-quantifiable IGSCC indications on the 400/100

kHz differential mix data

b) roll transition or crevice indications as identified from the MRPC

examination

The breakdown of corrective action (repairs) performed are as follows:

The A steam generator had a total of 88 tubes with indications identified by

eddy current, providing a total of 88 repairs.

The B steam generator had a total of 106 tubes with indications identified by

eddy current. Three (3) sleeved tubes were obstructed, two (2) sleeved tubes

had eddy current indications representative of PWSCC, one (1) sleeved tubes

had a blowhole indication in the lower portion of the weld, two (2) sleeved

Page 46 of 66

t

tubes had incomplete welds and six (6) sleeved tubes had welds with incomplete

fusion and all were subsequently plugged. A total of 120 repairs were made

in B steam generator.

A Ginna Steam Generator Tube Inspection and Corrective Action History has

been tabulated on page 68 as Table 5.

STEAM GENERATORTUBE INSPECTION AND CORRECTIVE ACTION HISTORY

COMMENTS(from TABLE5)

(1) Pulled R15 C55 and R17 C41 from the hot leg and R17 C40 from the cold leg to determine IGAconditions in the "B" steam generator. R17 C41 and ECT indications at all frequencies, R15C44 had only 100 kHz Absolute ECT indication and R17 C40 had no ECT indication. Both hotleg tubes had approximately 50% IGA, R17 C41 had a 60% SCC indication associated with theIGA,.

(2) Manually sleeved 5 tubes with nickel plated Inconel 600 thermally treated sleeves. Three tubeshad IGA indications, two others were preventatively sleeved.

(3) Sleeved 16 tubes with co-extruded sleeves, 13 with defects and 3 preventatively. Pulled Hot Legtubes R21 C46 with a 100 kHz ECT indication, R7 C45 and R28 C45 which were clean tubes.

(4) Recovery from the January 25, 1982 Tube Rupture Event including removing 26 tube sectionsby EDM and ID cutters along with the one tube pulled from the secondary side.

(5) The four tubes identified with IGA in the "A"steam generator were sleeved with 22" tubesheetsleeves. The 78 tubes identified in the "B"steam generator with IGA and/or SCC in the crevicewere repaired as follows:

tubes were sleeved with 36" brazed sleevestubes were sleeved with 28" brazed sleevestubes were sleeved with 22" tubesheet sleevestube and 2 sleeves were pluggedtube R34 C54 was pulled for metallurgical analysis

(6) The two tubes identified with IGA in the crevice in the "A" steam generator inlet were sleevedwith 20" tubesheet sleeves. One indication )40% TWD in the U-bend was permanentlyplugged. The 70 tubes identified in the "B" steam generator were repaired as follows:

561031

tubes were sleeved with 20" tubesheet sleevestubes were sleeved with 36" brazed sleevestubes were mechanically plugged (CE removable)tube was explosively plugged

Page 62 of 66

1 tube was sleeved with a 36" brazed sleeve due to the domino effect.

(7) The five tubes identified with crevice indications in the "A"steam generator inlet were sleevedwith 27" Combustion Engineering (CE) Sleeves. One tube identified ivith an O.D. generalindication above the secondary side tubesheet was also sleeved with a 27" CE sleeve. The 57tubes identified in the "B" steam generator were repaired as follows:

27273

tubes were sleeved with 27" CE sleevestubes were mechanically plugged (CE removable)CE Mechanical Plugs installed in 1985 were removed and sleeved with 27"sleeves

The present sleeve installation status is 83 brazed sleeves, 88 tube sheet sleeves, 30 welded CEsleeves in the "B" steam generator with 6 tubesheet sleeves and 6 welded CE sleeves in the "A"steam generator.

(8) The 34 tubes identified with crevice indications in the "A"steam generator inlet were repairedas follows:

10 tubes were mechanically plugged (CE removable)24 tubes were sleeved with 27" CE welded sleeve

The 153 tubes identified with crevice indications in the "B" steam generator inlet were repairedas follows:

72801

tubes were mechanically plugged (CE removable)tubes were sleeved with 27" CE welded sleevesCE welded sleeve (installed in 1987) was plugged with a CE welded sleeve plugdue to rejection of upper weld.

Other repairs required in the "B" steam generator are as follows:

BOW test brazed sleeves (installed in 1980) were plugged due to the loss ofthe primary to secondary pressure boundary as detected by the Hydro Test.Westinghouse explosive plugs installed prior to 1987 were removed due toleakage and replaced with CE welded plugs,CE Mechanical Plug on the cold leg was removed and replaced with a CEMechanical Plug.CE welded sleeves (installed in 1987), are considered as "leak limiting"due tothe marginal acceptance of the upper welds.

(9) In the "A" steam generator, 15 tubes were plugged as follows:I

7 tubes had tubesheet crevice indications7 tubes for no confirmed AVB support1 CE sleeve for unverified upper expansion

Explosive Plugs were removed and replaced with welded"Top Hat" Plugs

(10) The "B" steam generator had 9 tubes plugged for the following reasons:

tubes had tubesheet crevice indications identified by a review of the February'ata. These were removed from service with CE mechanical plugs.

tubes had signal changes from February to March, The tubes were removedfrom service with CE mechanical plugs.B&W tubesheet sleeve identified by the hydrostatic pressure test was removedfrom service with a B&Wexplosive plug in the hot leg and a CE mechanical inthe cold leg,
