1.0 INTRODUCTION

Unit 2 at Byron Station operates with four Westinghouse Model D-5 recirculating steam generators in the four ;

loop pressurized water reactor system. The steam generators contain thermally treated mill annealed Inconel 600 U-tubes that have a-nominal outside diameter:

of 0.750 inches and a nominal thickness of'0.043 inches.

In compliance with: Byron Station _ Technical Specification 3/4.4.5 and-ASME Section-XI,:IWB 2500,:1983_ Edition through Summer 1983cAddenda,- Steam Generator eddy curront examinations were conducted by Babcock & Wilcox during the Unit 2 cycle-21 refuel-ing. outage ~1n September ,

The scope of examinations of each steam

=

of 1990.

generator consisted of.100%-inspection of;all' hot leg tubes through the U-bend.and approximately 50%-of the-cold leg _ tubes.

2.0

SUMMARY

As a result of the' eddy current inspections-a total of ;

twenty one tubes were-removed from service (plugged) in all four steam generators combined. Refer to Table 2 for a listing,of tubes plugged during this outage.

Twenty of these tubes contained indications lof ;40%

through wall or greater and one tube that-contained an ,

indication less than 40%~through_ wall was preventatively '

plugged due to an- unfavorab: s trend. .

The following is an-examination summary of eachLsteam' generator:

- 3 .1 The examination and evaluation procedures used during the eddy current inspections were approved-by personnel qualified to Level III-in accordance with the 1980 Edition-of SNT-TC-1A. -The procedures were.

approved in accordance with Babcock & Wilcox and-Commonwealth Edison procedures.

3.2 The personnel who performed the eddy current inspections were qualified to Level I and Level II

-in accordance with the 1980 Edition of SNT-TC-1A Babcock & Wilcox Procedures,'and Commonwealth Ed1 son procedures. The Level I personnel-performed the inspections under the direct supervision of Level II personnel.

3.3 The personnel who performed the data analysis were qualified to'a minimum of Level II,-with special analysis training 1(IIA)-in accordance with the 1980; Edition of SNT-TC-1A, Babcock'& Wilcox procedures, and Commonwealth Edison procedures.

O .

3.4- The examinations, equipment, and-personnel-were in compliance with the requirements of the Babcock &

Wilcox SPIS QA manual for Inservice-Inspection,-Byron Station Technical-Specification-4.4.5, the 1983-Edition through Summer 1983 Addenda.of'Section XI ;of the-ASME-Boiler and Pressure Vessel Code, and industry standards.

3.5 Certification packages for examiners, data evaluators, and equipment are available at Byron Station.- Table 3 providos a listing of the certified.

personnel who performed, supervised,:or evaluated the-examinations. .

4.0 EXAMINATION TECHNIQUE 4.1 The eddy current examinations were performed with:a

0. 610 -inch diameter ULC bobbin coil- probe - or a 0. 590 '

inch diameter spring flex bobbin coil probe-for partially obstructed tubes.- The examination frequencies consisted of=10, 130, 300,-and 550 KHz generated by a Zetec-18A remote! digital acquisition unit in the absolute and differential modes. A 550/130 KHz tube support differential mix was used to enhance detection at tube support plates by suppressing the support signal. A 300/130-KHz antivibration bar absolute mix was used to enhance detection at antivibration barsuby suppressing the antivibration bar signal. 'A 550/300/130.KHz differential mix was used to enhance detection at-the tubesheet roll transistion regions.

4 ~. 2 The primary analysis of the eddy current data utilized Zetec's 200/300 series software' Edition.18.6 Revision 5.2.- The secondary analysis was performed using the Babcock & Wilcox Automated Data Screening-

' UNIX / ADS system. Any discrepancies between the primary and secondary analysis were resolved-by the on-site Level III Analyst.

4.3 The results of the data analysis were recorded on-Zetec's MIZ-18 DDA-4 data disks. The data was loaded into the Babcock & Wilcox Data Management 1 System to review'for invalid analysis entries, to sort data, to L ensure all tubes were properly examined and analyzed, l and to print out final data sheets and tubesheet maps . -

l 4.4 The eddy current inspections were witnessed and/or i verified by the Authorized Nuclear-Inservice Inspector, Mr. J. Hendricks, of the Hartford Steam Boiler Inspection and Insurance Company of Hartford Connecticut, Chicago Branch,-300 South Riverside j -Plaza, Suite 700 North, Chicago Illinois 60606.

5.0 EXAMINATION SCOPE 5 .- l Eddy current inspections were conducted on 100% of hot leg tubes from :the hot leg tube end through the U-bend to the top support plate on the cold leg side in all steam generators.

5.2 Eddy current inspections were conducted on cold leg tubes from the top support plate on-the cold leg to-

~

the cold leg tube end on the following tubes in each steam generator:

All~ tubes with previous indications-(%TW and signal-to-noise) - that were lef t inservice.-

- All tubes in rows 1, 2, and-44'through 49.

All tubes three deep along the T-slot and the curved portion of-the periphery.

- A sample of interior tubes, approximately 25%

of the tubes.

Figures 1A, 1B, 1C, and 1D indicate the inspection scope for each steam generator .

6.0 EXAMINATION RESULTS.

6.1 2A Steam Generator - 2RC01BA Hot leg inspections were. performed on 4564 tubes (100%) and cold leg inspections were performed on 2270 tubes (49.7%). As-a result ofLthese-inspections one (1) tube, 38-17, was removed from service due to

'antivibration bar wear of 43%-through wall. This tube was the only tube in this steam generator to-have been removed from service during this' outage. ,

A total of 38 tubes contained indications of 20-39%

through wall. Thirty six (36 of these tubes-contained indications of antiv)ibration bar wear.- -The remaining two tubes 42-83 and 15-20 contained general OD degradation that showed no growth since

, - the previous refueling inspection.

l l Table 1A, ASME Form NIS-BB, indicates inspection results of tubes that contained indications.of 20%

through wall or greater. Figure 3A,2A: Steam Generator. Indication Map, shows the location in the steam generator of the indications found.

6.2 2E Steam Generator - 2RC01BB

Hot. leg inspections were performed on-4562 tubes-(100%) and cold leg inspections were performed on 2268 tubes-(47.7%). As a-result of these inspectionr.

17 tubes were removed from service.- Table 2,1 Tubes-Removed From Service,-lists those-tubes; removed from service. Sixteen- of these tubes contained- 4 indications of-40%(16) through wall or gtsater.due to antivibration bar wear. Tube:39-97 was-preventatively jlugged due to antivibrationTbar wear-of 36%, 19%, andl16%<that showed an: excessive growth ,

rate.

Forty five (45) tubes' contained indications:of 20-39%

through wall. Antivibration bar. wear;was indicated-in 43 of these tubes. The remaining ltwo1 tubes, 11-54 ,

-and 48-43, contained manufacturing burnish marks.

Table 1B, ASME Form NIS-BB, indicaten' inspection 4 results of tubes that' contained indications of 20%

through wall or greater. ~ Figure 3B~,i2B Steam Generator Indication Map, shows the : location of the indications in the steam generator.

6.3 2C Steam Generator - 2RC01BC Hot leg inspections were performed on 4563 tubes (100%) and cold leg inspections were performed on 2272 tubes (49.8%). As a result.of these inspections, one tube 33-66.wasiremoved from service due to a 53% through wall: indication that' appears to-be caused by secondary side-pitting near'the eighth ;

support plate on the hot leg side.

Nineteen (19) tuber contained indications-of 20-39%

through wall. .Antivibration bar wear was found in'18 l of these tubes. Tube 25-15 contained a: manufacturing

l. burnish mark.

Table 1C, ASME Form NIS-BB, indicates inspection results of tubes that contained indications of 20%

through wall or greater. Figure 3C, 2C Steam l Generator' Indication-Map,..shows the' location-of the indications in the steam generator.

6.4 2D Steam Generator - 2RC01BD Hot leg inspections were performed on-4569 tubes

-(100%) and cold leg inspections were performed on 2273 tubes (49.7%). As a result of-these inspections, two tubes, 44-74 and 46-59, were removed from service due to degradation exceeding 40%-through wall.
