UNIT 2 STEAM GENERATOR EDDY'CURRENT EXAMINATION

1. 0

SUMMARY

On February 20, 1988, Unit 2 was shut down for its first refueling outage. A full Technical Specification examination was performed with an initial sample of approximately 2800 tubes in each steam generator. All tubes were examined from the cold leg side and all tubes were examined full length, to the extent practical, with the exception of row 1 and some row 2 tubes which were examined through the U-bed. The initial results fell into category C-2 in both steam generators. 'n additional sample of approximately 750, tubes were tested in each generator and all of the results fell into category C-1.

However, due to available time, testing continued in each steam generator.

A total of 10,931 tubes was tested in Steam Generator 21 and a total of 4707 tubes was tested in Steam Generator 22. 2.0 EXAMINATION RESULTS 1 The Steam Generator tubes with indications can be grouped into five categories. These categories are: ""~ Cold "leg 'corner'eggcrate-supports Central cavity batwings Outer periphery batwings Vertical supports and upper eggcrates Other indications 2.1 The examination revealed additional (from previous examination) wear indications at the lower eggcrate supports on the cold leg side of both steam generators in the low row corners of the tube bundles. SG 21: 3 degraded tubes 2 < 20X wear SG 22: 2 defective tubes 3 degraded tubes 2 < 20X wear 2.2 In the central cavity batwing wear area, a small number of degraded tubes was found. The central cavity batwing area is the area adjacent to the stay cylinder. SG 21: 1 degraded tube SG 22: 3 degraded tubes

2.3 On the outer periphery tubes some random batwing wear was found during the examination. SG 21: 1 defective tube 2 < 20X wear SG 22: 1 defective tube 3 degraded tubes 1 < 20X wear 2.4 Vertical support and upper eggcrate wear was found randomly distributed throughout the steam generator tube bundles. SG 21: 3 defective tubes 17 degraded tubes 44 < 20X wear SG 22: 1 defective tube 5 degraded tubes 31 < 20X wear 2.5 Other indications were found in tubes in the steam generator bundle which do not fit into the above categories. These indications were randomly spaced in the generator and the indications were found at different elevations in the tubes. '"SG 21: 1 defective tube 6 degraded tubes 21 < 20X wear SG 22: 2 defective tubes 5 degraded tubes 4 < 20X wear The summary data sheets in Appendix A list all of the tubes in both steam generators which showed 20X or greater indications during the Eddy Current Testing. Several tubes with indication were examined with 8 x 1 pancake coil and roto probe. Appendix B has the tubesheet maps which show the extent tested and the location of the 0 100X indications for Steam Generator 22. Steam Generator 21 was tested essentially 100X so Appendix B has the 0 100X indication map only. The NIS-1 Form in Appendix C lists which tubes were plugged. The following Engineering Evaluation Requests (EER) were initiated to track the examination results and subsequent plugging: 88-RC-096, 88-RC-097 and 88-RC-126. 3.0 EXAMINATIONTECHNIQUES AND EQUIPMENT The eddy current examination was performed by Conam Inspection us'ing Zetec MIZ18 digital data acquisition and analysis systems. The following test frequencies were used during the examination: 550 kHz differential and Absolute 990 kHz differential and Absolute 100 kHz differential and Absolute 20 kHz differential and Absolute

The majority of the tubes in the examination were tested with Zetec manufactured 0.610" SMF/HF probes. The tubes in rows 1 through 10 were examined with a 0.590" SMF/HF probe. A modified Zetec SM-10 fixture was used for probe positioning from the cold leg manway.
