==SUMMARY==
==SUMMARY==
On January 17, 1987 a tube leak was observed in steam generator ll (Unit 1, steam generator 1).Unit 1 was subsequently shutdown on January 18, 1987 and work began towards opening the steam generators for eddy current examination.
Following removal of the manway covers, the leak was visual-ly identified as being in the low numbered row/low numbered column corner of the tube bundle on the cold leg side.A full Technical Specification examination was performed with an initial sample of approximately 2800 tubes in each steam generator, with all examinations performed from the cold leg.All tubes were examined full length with the exception of row 1 and some row 2 tubes which were examined to the first support on the hot leg side when possible.The initial examination results fell into category C-2 in both steam generators and an additional 716 tubes were examined in steam generator 11 and 696 tubes were examined in steam generator 12.The tubes in the expansion program were examined to the fourth support on the cold leg.The results of the supplementory testing fell into category C-l.2.0 EXAMINATION RESULTS The examination results revealed wear indications at the lower eggcrates on the cold leg side of both steam generators in the low row corners of the tube bundles.A total of fourteen degraded tubes and seven defec-tive tubes were identified in steam generator ll, and thirteen degraded tubes and six defective tubes were identified in steam generator 12 (Unit 1, steam generator 2).The summary data sheets in Appendix A list all tubes in both steam generators with thru-wall indications from 0-100K and distorted tube support signals with probable indications (DSI).Several tubes were identified in each steam generator as having minor dings and dents.The majority of these had been identified during base-line examinations, however, the following tubes in steam generator ll showed significant denting at the feedwater flow distribution baffle that was not present during the baseline examination:
Row 1 column 50, row 1 column 52, row 1 column 54, rowl column 56, row 1 column 60, row 1 column 62, and row 1 column 64.In addition, row 1 column 58 was dented to the point of 0.540" probe would not pass.Steam generator 11 had sixteen tubes in the examination sample that were not explanded into the tubesheet while steam generator 12 had fourteen tubes with no tubesheet explansion.
Possible loose part indications were observed in both steam generators with steam generator 11 having five tubes and steam generator'12 having one tube.Sludge profiling was also performed during the examination and was found to be very minor.Less than 100 tubes in each steam genera-tor showed any indication of sludge with average depth less than an inch and maximum depth 1.5 inches.Page 1 of 2


The examination resulted in plugging an additional 20 tubes in steam generator ll, and 14 tubes in steam generator 12.The tube sheet maps in Appendix B show the total tubes plugged in each steam generator to date and the examination extent during this outage.The NIS-1 form in Appendix C lists each of the tubes, by row and column, plugged as a result of this examination.
On  January 17, 1987 a tube leak was observed in steam generator       ll (Unit 1, steam generator 1). Unit 1 was subsequently shutdown on January 18, 1987 and work began towards opening the steam generators for eddy current examination. Following removal of the manway covers, the leak was visual-ly identified as being in the low numbered row/low numbered column corner of the tube bundle    on the cold leg side.     A full Technical Specification examination was performed with an initial sample of approximately 2800 tubes in each steam generator, with all examinations performed from the cold leg. All tubes were examined full length with the exception of row 1 and some row 2 tubes which were examined to the first support on the hot leg side when possible.
The following Engineering Evaluation Requests (EER)were initiated to track the examination results: 87-RC-035, 87-RC-037, 87-RC-038 and 87-RC-039.
The  initial examination    results fell into category C-2 in both steam generators and an    additional  716 tubes were examined in steam generator 11  and  696 tubes  were  examined  in steam generator 12. The tubes in the expansion program    were  examined  to the fourth support on the cold leg.
In addition,'
The results of the supplementory testing fell into category C-l.
report on the steam generators, including root cause analysis, was transmitted to NRR by letter ANPP-40179-JGH/BJA/98.05.
2.0 EXAMINATION RESULTS The examination   results revealed wear indications at the lower eggcrates on the cold leg    side of both steam generators in the low row corners of the tube bundles.      A total of fourteen degraded tubes and seven defec-tive tubes  were identified in steam generator ll, and thirteen degraded tubes and six defective tubes were identified in steam generator 12 (Unit 1, steam generator 2). The summary data sheets in Appendix A list all tubes in both steam generators with thru-wall indications from 0-100K and distorted tube support signals with probable indications (DSI).
3.0 EXAMINATION TECHNIQUES AND EQUIPKBlT The eddy current examination was performed by Conam Inspection using Zetec MIZ-18 digital data aquisition and analysis systems.The following test frequencies were used during the examination:
Several tubes were identified in each steam generator as having minor dings and dents. The majority of these had been identified during base-line examinations, however, the following tubes in steam generator        ll showed significant denting at the feedwater flow distribution baffle that was not present during the baseline examination: Row 1 column 50, row 1 column 52, row 1 column 54, rowl column 56, row 1 column 60, row 1 column 62, and row 1 column 64.         In addition, row 1 column 58 was dented to the point of 0.540" probe would not pass.
550 kHz differential and absolute 300 kHz differential and absolute 100 kHz differential and absolute 20 kHz differential and absolute The majority of the tubes in the examination sample were tested with Zetec manufactured 0.610" and 0.600" SFM/HF probes.The tubes in rows 1, 2, and 3 were examined with either 0.590" or 0.540" SFM/HF probes.A Zetec SM-4 remote fixture was used for probe positioning and tubesheet templates were installed for tube location verification.
Steam  generator 11 had sixteen tubes in the examination sample that were not explanded into the tubesheet while steam generator 12 had fourteen tubes with no tubesheet explansion.

Possible loose part indications were observed in both steam generators with steam generator 11 having five tubes and steam generator'12 having one tube. Sludge profiling was also performed during the examination and was found to be very minor. Less than 100 tubes in each steam genera-tor showed any indication of sludge with average depth less than an inch and maximum depth 1.5 inches.

SUMMARY

On January 17, 1987 a tube leak was observed in steam generator ll (Unit 1, steam generator 1). Unit 1 was subsequently shutdown on January 18, 1987 and work began towards opening the steam generators for eddy current examination. Following removal of the manway covers, the leak was visual-ly identified as being in the low numbered row/low numbered column corner of the tube bundle on the cold leg side. A full Technical Specification examination was performed with an initial sample of approximately 2800 tubes in each steam generator, with all examinations performed from the cold leg. All tubes were examined full length with the exception of row 1 and some row 2 tubes which were examined to the first support on the hot leg side when possible.

The initial examination results fell into category C-2 in both steam generators and an additional 716 tubes were examined in steam generator 11 and 696 tubes were examined in steam generator 12. The tubes in the expansion program were examined to the fourth support on the cold leg.

The results of the supplementory testing fell into category C-l.

2.0 EXAMINATION RESULTS The examination results revealed wear indications at the lower eggcrates on the cold leg side of both steam generators in the low row corners of the tube bundles. A total of fourteen degraded tubes and seven defec-tive tubes were identified in steam generator ll, and thirteen degraded tubes and six defective tubes were identified in steam generator 12 (Unit 1, steam generator 2). The summary data sheets in Appendix A list all tubes in both steam generators with thru-wall indications from 0-100K and distorted tube support signals with probable indications (DSI).

Several tubes were identified in each steam generator as having minor dings and dents. The majority of these had been identified during base-line examinations, however, the following tubes in steam generator ll showed significant denting at the feedwater flow distribution baffle that was not present during the baseline examination: Row 1 column 50, row 1 column 52, row 1 column 54, rowl column 56, row 1 column 60, row 1 column 62, and row 1 column 64. In addition, row 1 column 58 was dented to the point of 0.540" probe would not pass.

Steam generator 11 had sixteen tubes in the examination sample that were not explanded into the tubesheet while steam generator 12 had fourteen tubes with no tubesheet explansion.

Possible loose part indications were observed in both steam generators with steam generator 11 having five tubes and steam generator'12 having one tube. Sludge profiling was also performed during the examination and was found to be very minor. Less than 100 tubes in each steam genera-tor showed any indication of sludge with average depth less than an inch and maximum depth 1.5 inches.

Page 1 of 2

The examination resulted in plugging an additional 20 tubes in steam generator ll, and 14 tubes in steam generator 12. The tube sheet maps in Appendix B show the total tubes plugged in each steam generator to date and the examination extent during this outage. The NIS-1 form in Appendix C lists each of the tubes, by row and column, plugged as a result of this examination. The following Engineering Evaluation Requests (EER) were initiated to track the examination results: 87-RC-035, 87-RC-037, 87-RC-038 and 87-RC-039. In addition,' report on the steam generators, including root cause analysis, was transmitted to NRR by letter ANPP-40179-JGH/BJA/98.05.

3.0 EXAMINATION TECHNIQUES AND EQUIPKBlT The eddy current examination was performed by Conam Inspection using Zetec MIZ-18 digital data aquisition and analysis systems. The following test frequencies were used during the examination:

550 kHz differential and absolute 300 kHz differential and absolute 100 kHz differential and absolute 20 kHz differential and absolute The majority of the tubes in the examination sample were tested with Zetec manufactured 0.610" and 0.600" SFM/HF probes. The tubes in rows 1, 2, and 3 were examined with either 0.590" or 0.540" SFM/HF probes.

A Zetec SM-4 remote fixture was used for probe positioning and tubesheet templates were installed for tube location verification.
