1.0 INTRODUCTION

The following is a sumniary repoit of the results of the multifrequency eddy

current examination performed during the 1992 Annual Refueling and

Maintenance Outage at the R. E. Ginna Nuclear'ower 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 cur rent examination was to assess any corrosion or

mechanical damage that may have occurred during the cycle since the 1991

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) Intergranular attack (IGA)and intergranularstress corrosion cracking

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

3) Primary water stress corrosion cracking (PWSCC) at. the inlet

tubesheet roll transition.

Page 1 of 72

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 V-bend

region.

7) Denting at tube support intersections.

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

Row 2 U-bend area (none detected).

9) Intergranular attack (IGA)and intergranularstress corrosion cracking

(IGSCC) at the ¹1 tube support plate region on the inlet side (none

detected).

10) Stress corrosion cracking (SCC) at the ¹6 tube support plate region

with dents (none detected).

The examination was performed by personnel from Rochester Gas and

Electric (RG&E) and Allen Nuclear Associates, Inc. (ANA). 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 II for

data analysis. 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-

Page 2 of 72

RG&E,Ginna Station". These analysis guidelines were prepared in

accordance with Revision 2 of the Electric Power Research Institutes (EPRI)

"PWR Steam Generator Inspection Guidelines".

The data analysis was performed by two independent teams. Both teams

performed their analysis manually utilizing the Zetec Digital Data Analysis

(DDA-4) System. The results of these two analyses were compared for

discrepancies using the ISIS-TVBE computerized data management system.

The typical data flow chart is shown on Figure 1 (). The following list

describes some typical discrepancies between analysis teams requiring

resolution by the Level III resolution team.

o Any indication that is reported as )20% by either team and is not

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

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

o Any difference of ) 1 inch in the axial location of a fiaw.

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

have been missed or improperly entered by one analysis team).

Any difference in the repo«ed test extent.

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

one or both parties have reported it.

Page 3 of 72

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

have been missed or improperly entered by one analysis team).

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

other.

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

other.

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

or both teams were reviewed by the resolution team (usually consisting of two

Level III individuals). In ~ll cases; the removal of a repairable indication

from the data base required the concurrence of two Resolution personnel.

2.0 DATA AC UISITION PROGRAM

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

ivas performed utilizing the Zetec 3-coil Motorized Rotating Pancake Probe

(MRPC) and the Zetec Miz-18 Digital Data Acquisition System. The

frequencies selected iver e 400, 300, 100 and 25 kHz. The examination was

performed primarily through the full length of the tube sheet region to

examine the open crevice and roll transition regions.

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

were performed utilizing the standard 0.740" or 0.720" O.D. bobbin coil

probe. The frequencies selected were 400, 200, 100 and 25 kHz. Smaller

diameter probes were used to traverse the smaller radius U-bends and dented

regions.

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 to the top of the tube sheet with MRPC, along with

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

Page 6 of 72

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. AllRow

I and Row 2 U-bend regions selected as part of the 20% random sample were

examined with the Motorized Rotating Pancake Coil (MRPC) between the

06H and 06C from the cold leg side.

A number of supplemental examinations were also performed to assist in fiaw

characterization and confirmation and to continue to monitor for the onset

of new damage mechanisms.

Table 1 is a breakdown, by steam generator, of all tubes programmed for

examination, numbers examined and the extent examined.

3.0 DATA ANALYSIS RESULTS SUMMARY

The data analysis was performed using the Zetec DDA-4 Digital Data

Analysis System with Edition 18.6 Revision 5.2 software and MRPC (Revision

14) supplements.

For the MRPC evaminations, all data was reviewed by displaying the 400

kHz or 300 kHz pancake coil data on the CRT 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 data. Any tube

containing a flaw detected by the MRPC examination was repaired.

For the bobbin coil exainination, all data was reviewed by displaying the

400 kHz data on the CRT 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.

Allrecordable indications were logged into the computer and stored on floppy

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 Table 2. An explanation of the abbreviations and

nomenclature used on these lists has been compiled for ease of interpretation.

4.II O~SK VAT NS

The 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 118 new crevice indications reported. In the "A"

steam generator, 34 new crevice indications were reported.

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

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

increase in PWSCC at the roll transition during the last operating cycle.

This mechanism was first addressed in 1989 and this year there were 63 Roll

Transition (PWSCC) indications in "B" steam generator and 189 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 the tubes, generally toward the center of the bundle, have this condition.

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

showed an increase in the growth rate for several cycles. Three tubes in the

"A" steam generator were listed for corrective action from this condition.

These tubes were essentially unchanged from prior inspections but were

repaired as a preventative measure. It is believed that these 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.

Page 49 of 72

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 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 wer e seen.

The denting phenomenon and n>inor distortions at the tubesheet and support

plates can be attributed to secondary side corrosion product buildup in the

annularregion between the tube outside surface and the carbon steel support

member. Comparisons with previous data indicates that a small increase in

the extent or magnitude of denting has occurred from what has been detected

by previous inspections.

Indications were detected at the support plates in per iphery tubes on the cold

leg of the "8" steam generator. These indications were present and recorded

in previous years a»d wer e progr amined as par t of the ) 20% TW

examination. Two tubes were listed for cor rective action from this condition.

These tubes were essentially unchanged from prior inspections but were

repaired as a preventative measure.

Page 50 of 72

MRPC at the PI tube support plate intersections in the Hot Leg of both

steam generators showed no indications ivithin the support plates. This

sample included tubes with and without denting at the support intersection.

MRPC at //6 tube support plate intersections with dents in the Cold Leg of

both steam generators showed no indications in or near the support plates.

The eight (8) tubes in the "A" Steain Generator recorded with indications at

the anti-vibration bar intersections iver e examined again to monitor growth

rates. These indications are less than the repair limit. Many of them were

recorded in earlier outages and have not changed significantly since previous

examinations. In light of the fact that only a small number of tubes exhibit

these indications and no measurable groivth has been noted, AVB fretting

wear is not considered to be an active damage mechanism or major concern

at this time but will be periodically tnonitored for any growth.

In summary, the "A" Steam Generator had 223 tubes that ivere found to

have "new" tubesheet crevice indications (34 IGA/SCC and 189 roll

transitions). The "B" Steam Generator had 181 "new" tubesheet crevice

indications (118 IGA/SCC and 63 roll transitions).

Page 51 of 72

5.0 CORRECTIVE ACTION

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) an absolute drift signal (ADS) of the Mix-2 Channel

b) quantifiable IGSCC indications on the 400 kIIz data

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

examination

There were 16 tubes deplugged in the "A" generator and 30 tubes deplugged

in the "B" generator in an effor t to return them to service by sleeving. These

tubes were recorded with repairable indications in earlier outages. A full

length examination was performed after deplugging to insure no indications

existed that would prevent theln fronl being returned to service.

Page 52 of 72

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

The A steam generator had a total of 226 tubes with indications identified by

eddy current. Sixteen (l6) deplugged tubes were returned to service by

sleeving. Two (2) tubes were stabilized for AVB concerns. A total of 244

repairs.

The B steam generator had a total of 183 tubes with indications identified by

eddy current. Three (3) B8c>V evplosive plugs 'were repaired. Of the 30

deplugged tubes, 29 tubes were returned to service by sleeving (1 deplugged

tube was re-plugged). Two (2) tubes were stabilized for AVB concerns. A

total of 218 repairs.

A Ginna Steam Generator Tube lnspectio» and Corrective Action History has

been tabulated or> page 68 as Table 5.
