, INTRODUCTION Byron Nuclear Power Station is a two unit site, owned and operated by the Commonwealth Edison Company._ Each unit utilizes a Westinghouse design Nuclear Stemn Supply System, which includes a four loop i

pressurized water reactor rated at 3411 megawatts-thermal, four recirculating steam generators, and a turbine generator, rated at 1175 megawatts-electrical.

I Eddy current (ET) examinations were conducted by Babcock & Wilcox Company personnel on Byron's four Unit I recirculating steam generators during the cycle 3 refueling outage in January and February of 1990.

The reope of examinations consisted of 100% of all steam generator tubes inspected from the eleventh support plate on the cold leg through the U-bend to the tube sheet on the hot leg.

Approximately 50% of all tubes in each steam generator were inspected full length, tubecheet to tubesheet.

The tubes in the four steam generators are made of Inconel 600 with a nominal outside diameter of 0.750 inches and a nominal thickness of 0.043 inches.

3.0 CERTIFICATIONS 3.1 The exnmination and evaluation procedures used during the Eddy Current inspection were approved by personnel qualified to j

Level III in accordance with Babcock & Wilcox Procedure ISI-24, 3.2 The steam generator tubing examinations were perfermed by personnel qualified to Level I under the direct supervision of.

)

personnel qualified to Level II in accordance with Babcock &

)

Wilcox Procedure ISI-24.

l 3.3 The Eddy Current data was evaluated by. personnel quallfled to a j

minimum of Level IIA in accordance with Babcock and Wilcox Procedure ISI-24.

}

3.4 The examinations, equipment, and personnel were in compliance with

4.0 EXAMINATIONS 4.1 The Eddy Current examinations were perf orme6 with a 0.610" diameter ULC bobbin coll probe or a 0.590" diameter spring flex

. bobbin coil probe for partially obstructed tubes. The examination frequencies consisted of $50, 300, 100, and 35 Kitz generated by a Zetec MIZ-18 remote digital acquisition unit in both the absolute and differential modes.

A 550/100 KHz differential tube support plate (TSP) differential mix was used to enhance detection at the t

TSP by suppressing the TSP signal.

A 300/100 Kitz absolute mix was used to enhance detection of anti-vibration bar wear in the U-bend region. A 550/300/100 differential mix was used to enhance detection in the tubesheet roll transition region.

4.2 The official results of the data analysis were recorded on the MIZ-18 DDA-4 data disks and then loaded into a data management system. The data management system performed the following functionst a) screen analysis entries for invalid data, I

b) perform data sorting routines, c) verify inspections are complete on all tubes within examination scope, and I

d) provide tube sheet maps of tubes removed from service and all indications found during inspection.

4.3 Dabccck & Wilcox Automated Data Screening (ADS) was utilized as a second, independent data review.

Any discrepancies between the primary analysis and ADS were resolved by the on-site Babcock &

Wilcox Level III analyst. The final report reflects all resolutions.

4.4 The Eddy Current inspections were witnessed and/or verified by the Authorized Nuclear Inservice Inspector, Mr. J. Hendricks, of

-Ilartford Steam Boller Inspection and Insurance Company of Hartford, Connecticut, Chicago Branch, 300 South Riverside Plaza Suite 700 North, Chicago, Illinois 60606.

5.0 SCOPE The Eddy Current examination scope for each steam generator consisted of full length inspections (tubesheet to tubesheet) of the following:

- All tubes with previous % thtouch wall (TW) indications including signal-to-noise ludicationn.

-- All tubes in rows J.

2, and 44 throuqh 49.

- All tubes three deep along t.he T-nlot and the curved portion of the periphery.

- A sample of interior tuben, approximately 25% of tubes.

I Partial length Eddy Current examinations, extending f rom the hot leg i

tubesheet through the U-bend to the top support plate on the cold leg, I

were performed on all remaining tubes, thus completing a 100% inspection of all tubes.

6.0 RESUbTS 6.1 1A Steam Generator - 1RC01DA Full length inspections were performed on 2235 tubes and partial length inspections were performed on 2304 tubes for a 100%

examination scope.

Five tubes were identified to contain Indications greater than 20% TW with two tubes with indications greater than or equal to 40%.

Refer to Table 1, Form NIS-DB, for results.

Fivs tubes were removed from service by mechanical roll tube plugs.

Tube 7-39 contained 40% TW degradation in the hot leg tubesheet roll transition area.

This tube was subsequently plugged.

Tube 24-46 contained a 63% OD indication at the 9H support plate that is attributed to secondary side pitting. This tube was also plugged. The other tubes, 46-75, 48-36, 36-15 contained indications between 20-39% TW with common mode degradation of secondary side pitting near support plates. Tubes 46-75, 48-36, and 36-15 were plugged due to 38%, 34%, and 21% TW degradation respective 11y.

Tube 46-74 plugged with 0% TW degradation.

6.2 1B Steam Generator - 1RC01BB Full length inspections were performed on 2264 tubes and partial length inspections were performed on 2298 tubes for a 100%

examination scope. Two tubes were identified to contain indications greater than 40% TW and no tubes contained degradation in the 20-39% TW range. Refer to Table 2, Form HIS-BD, for results. Two tubes were removed from service by mechanical roll tube plugs.

Tubes 24-68 and 31-86 contained OD degradation indicative of secondary side pitting that was 77% and 76% TW respectively, These tubes were plugged.

i 6.3 1C Steam Generator - 1RC01DC Full length inspections were performed on 2300 tubes and partini l.

length inspectious were performed on 2209 tubes for a 100%

examination scope.

Six tubes contained indications granter than L

20% TW with four of those tubes with degradation exceeding 40% TW.

Refer to Table 3, Form MID-UB, for results.

Six tubes i

were removed from service.

l' (4)

h, F

i-Five tubes had common mode degradation of secondary side pitting near support plates.

Tubes 18-16, 34-15, 34-37, and 45-26 were plugged due to degradation exceeding 40% TW (80%, 58%, 62% and 62% TW respectively).

Tube 35-16 was preventively plugged due to 37% TW pitting. Tube 12-8 was plugged as a preventative measuro with a orificed plug in the cold leg due to a recommendaulon by Westinghouse as a result of a preliminary tube analysis. A 29% TW manufacturing burnish mark was found in tube 19-83.

The mark showed no growth from the previous inspection and was subsequently left in service.

l 6.4 1D Steam Generator - 1RC01BD Full length inspections were performed on 2264 tubes und partial length inspections were performed on 2303 tubes for a 100%

examination scope.

Five tubes contained indications greater than 20% TW with two of those tubes exceeding 40% TW degradation.

Refer to Table 4, Form NIS-BB, for results. Three tubes were removed from service by mechanical roll tube plugs.

All five tubes contained common mode degradation of secondary side pitting near support plates. Tubes 14-8 and 36-16 contained degradation exceeding 40% TW, 64% and 59% TW respectively. These tubes were subsequently plugged. Tube 29-80 was preventively plugged due to 38% TW pitting.
