1.0 INTRODUCTION

This report is a summary of the examinations performed during the First Inservice Inspection at Palo Verde Nuclear Generating Station Unit 2.

This was the initial ISI for Interval 1 Period 1 and was conducted during the first refueling outage which occurred from February 20, 1988 thru June 22, 1988. Palo Verde Unit 2 began commercial operation on September 19, 1986.

This report identifies the components examined, the examination methods used, the examination report number and summarizes the examination results for each of the following categories of items:

1. ASME Section XI Class 1 and 2 pressure retaining components and their supports.
2. Augmented high energy piping systems in accordance with PVNGS FSAR Section 6.6.8.

j

3. Augmented examinations of CHR, RHR, and ECCS piping systems in accor-dance with 10CFR50.55a.

2.0 EXAMINATION

SUMMARY

The evaluation of the results from the inservice inspection examinations indicated the integrity of the systems has been maintained. All discrep-ancies were corrected in accordance with PVNGS work control practices and ASME Section XI. The discrepant findings are noted as follows:

DISCREPANCY 3,4 SG Manway Studs Galled Threads/Corrosion 5 PZR Manway Studs Galled Threads/Corrosion 25 SI-156-H7 Loose hanger clamp locknut 29 29-11 Linear Indications 45 SG-42-H14 Linear Indications 45 SG-42-H15 Linear Indications Indications'inear 51 51-3 51 51-4 Linear Indications 51 51-6 Linear Indications 51 51-9 Linear Indications 58 58-19 Linear Indications 60 60-8 Linear Indications

'The discrepant items in Zones 29, 45, 51, 58 and 60 were repaired by light grinding/blending. The manway studs in Zones 3,4 and 5 were all damaged during removal (galled) and were replaced with new studs and nuts. A pre-service examination was performed on all replacement items, including three snubbers.

3.0 EXAMINATION TECHNIQUES The three types of examinations utilized to perform the Inservice Examina-tions along with the actual nondestructive examination technique, are identified in the legend below:

VT-VISUAL VT-1 GENERAL CONDITION VT-2 LEAKAGE VT-3 STRUCTURAL CONDITION VT-4 OPERABILITY S-SURFACE LIQUID PENETRANT MAGNETIC PARTICLE VOL-VOLUMETRIC ULTRASONIC All of the nondestructive examinations were performed using specific tech-niques and procedures that are indicated in ASME Section XI, or alternative examinations that are demonstrated to be equivalent or superior to those identified.

4.0 ACCESSIBILITY All items were examined to the extent practical. Any code limitations encountered during the examinations are documented in Appendix B.

5.0 PERSONNEL All nondestructive examinations were performed by ANPP, and Lambert, MacGill, Thomas, Inc. (LMT) personnel. All personnel were certified in accordance with programs written to comply with the applicable requirements of ASME Section XI. Copies of all certifications are maintained on file. Kemper Group, representing ANI, provided the Authorized Inspection.

6.0 EQUIPMENT AND MATERIALS The equipment and materials utilized were certified to the requirements of ASME Section XI. Copies of all certifications are maintained on file.

7.0 REPAIRS AND REPLACEMENTS All repairs and replacements were performed to ASME Section XI requirements.

The applicable records and reports for the specific repair or replacement are maintained on file.

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 EXAMINATION TECHNIQUES 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.
