UNIT 2 STEAM GENERATOR EDDY CURRENT U2 R12 Refueling Outage 1.0 Summary The steam generator eddy current examination for the 12th refueling outage in Unit 2 was conducted during April 2005. The initial examination plan for both steam generators are listed in Table 1. This table summarizes the examinations performed for each of the various categories, examination types, extents, and the number of tubes or tube locations completed.

The examinations resulted in a total of 8 tubes being plugged in SG 21, and 7 tubes being plugged in SG 22. A description of the plugging history for these replacement steam generators is contained in Appendix F along with tube plug maps illustrating the plug locations for this outage.

2.0 Original Examination Plan The original examination plan was developed based on the "PVNGS Steam Generator Degradation Assessment" developed per 81DP-9RC0I as required by NEI 97-06. In addition, possible damage mechanisms were reviewed along with the specific requirements set forth in 73TI-9RC01 and PVNGS Technical Specifications. The plan is summarized in Table 1 of this report. Appendix B contains the associated tube sheet maps for the various scopes.

Bobbin coil examinations were performed on essentially 100% of the tubing for general screening purposes, overall detection, and to satisfy Technical Specifications requirements.

3.0 Condition Monitoring and Operational Assessment Per NEI 97-06, and PVNGS Procedure 81DP-9RC01, a condition monitoring evaluation was conducted by PVNGS Engineering. The results indicate that the steam generator tube integrity performance criteria were satisfied for Cycle 12.

All defects exceeding the Technical Specification repair limits or the PVNGS Administrative Plugging criteria were removed from service. Based on a comparison of projected versus actual results for cycle 12,

there are no expected cycle length limitations for U2 cycle 13. As such there are no mode 4 entry restraints. An operational assessment as required by NEI 97-06 will document steam generator tube integrity will be satisfied for Unit 2 cycle 13.

4.0 Examination Results The examination results for each of the steam generators, per the PVNGS Technical Specifications, were classified as C-2. The classification criteria is based on Technical Specification examinations (full length bobbin) and classified per the following:

C-1; Less than 5% of the total tubes inspected are degraded tubes and none of the inspected tubes are defective.

C-2; One or more tubes, but not more than 1% of the total tubes inspected are defective, or between 5% and 10% of the total tubes inspected are degraded tubes.

C-3; More than 10% of the total tubes inspected are degraded tubes or more than 1% of the inspected tubes are defective.

Steam Generator 21 The bobbin coil eddy current examinations revealed 1 defective tube (> 40%) and 4 degraded

(>20%) tubes. RC examinations of dents detected 3 tubes containing abnormal dent indications. RC examinations performed on the periphery from the cold leg tube sheet to the 0IC eggcrate, did not reveal any tubes with loose parts containing associated wear.

Steam Generator 22 The bobbin coil eddy current examinations revealed 0 defective tubes and 5 degraded tubes.

RC examinations detected 1 tube containing an abnormal dent and 1 tube containing a small volumetric indication. RC examinations performed on the periphery from the cold leg tube sheet to the O1C eggcrate, did not reveal any tubes with loose parts containing associated wear.

A summary of the bobbin and RC examination results is located in Table 2 of this report. In addition, Appendix A contains a reference drawing of steam generator support locations. The summary data sheets of Appendix C and D list all tubes in each steam generator with indications expressed as a percent wall thickness reduction, or as an analysis code. Appendix E contains summary data sheets for tubes classified as possible loose parts.

5.0 Examination Techniques and Equipment The eddy current examinations were performed by Westinghouse Electric Company using Zetec MIZ-70 digital data acquisition instrumentation, Westinghouse Anser acquisition software, and consisted of both Anser and Eddynet analysis systems. The following frequencies were used for the tube examinations:

Bobbin Coil RC 500 KHz 800 KHz 300 KHz 300 KHz 100 KHz 100 KHz 35 KHz 35 KHz Notes: For bobbin coil examinations these frequencies were utilized in both differential and absolute modes. Also note that the 800 KHz frequency was utilized during low radius U-Bend examinations only.

All tubing was examined with Zetec manufactured bobbin coil probes and Zetec RC style probes. Probe diameters were 0.540" to 0.610". Plus Point RC probes were used for the detection and characterization of the volumetric indications. Data acquisition in both steam generators was facilitated by using Westinghouse Genesis fixtures configured with either a quad or dual guide tube in each of the hot and cold legs. In addition, the "rail" system was installed and utilized in both steam generators. This facilitates moving the fixtures in the channel heads remotely. Two of the newly designed Westinghouse Pegasys robots were also utilized initially in each cold leg and later moved to the hot legs.

Fiber optic cable was used from containment to the data acquisition room located at the PVNGS North Annex. Primary analysis was all performed on site, whereas secondary analysis was performed both remotely and on site. The remote site received the data and returned results utilizing T-1 line technology. The remote Secondary Analysts were located in the Anatec International Inc. facility at the SONGS site in San Clemente, California. The Primary and Secondary Resolution Analysts, Independent Review Analysts, and data management were located at PVNGS in the North Annex. Westinghouse provided the data acquisition and primary data analysis. Anatec International, Inc. provided the secondary data analysis.

Each individual from Westinghouse and Anatec International, Inc. who performed data analysis was required to complete and pass a PVNGS site specific Eddy Current Data Analysis Course as well as an associated performance examination with at least a 80%

proficiency. The only exceptions were the APS and Westinghouse Level III's due to their preparation of the site-specific test. All individuals performing data analysis were also required to have Qualified Data Analyst (QDA) certification.

6.0 Repair Techniques and Equipment All repairs were performed utilizing the Westinghouse mechanical rolled plug. The plugs were installed in accordance with the PVNGS work control process utilizing the Genesis fixtures and associated remote plugging equipment.
