UNIT 1 STEAM GENERATOR EDDY CURRENT Ul R13 Refueling Outage 1.0 Summary This report is intended to satisfy the requirements of PVNGS Technical Specifications 5.6.8 for the submittal of a Steam Generator Tube Inspection Report. The steam generator (SG) eddy current examination for the 13th refueling outage in Unit 1 (U1R13) was conducted during June 2007.
Mode 4 entry of Unit 1 Cycle 14 was entered on July 11, 2007. The initial examination plan for both steam generators is listed in Table 1. This table summarizes the examinations performned for each of the various categories, examination types, extents, and the number of tubes or tube locations completed. This was the first examination performed in Unit 1 following steam generator replacement in U1R12. This examination is considered a 100% full length tubing inspection (see Table 1) with the Row 1-4 u-bends inspected via rotating coil in lieu of bobbin due to access limitations of the selected bobbin probe sizes.
The examinations resulted in a total of 0 tubes being plugged in SG 11, and 0 tubes being plugged in SG 12. A description of the previous plugging history for these replacement steam generators is contained in Appendix E.
2.0 Original Examination Plan The original examination plan was developed based on the "PYNGS Steam Generator Degradation Assessment" developed per PVNGS Procedure 8 1DP-9RC01I as required by NEI 97-06. In addition, possible damage mechanisms were reviewed along with the specific requirements set forth in Procedure 73TI-9RCO1I and the PVNGS Technical Specifications. The plan is summarized in Table I of this report.
3.0 Condition Monitoring Assessment Per the Steam Generator Program, as defined in PVNGS Procedure 81 DP-9RCO 1, a condition monitoring evaluation was conducted by PVNGS Engineering. As indicated above, no defects exceeding the Technical Specification repair limits or the PVNGS Administrative Plugging criteria were identified. The results of the eddy current examinations are provided in Section 4.0. An engineering evaluation of the as-found condition of inservice tubes did not reveal any degradation exceeding the threshold values for structural and leakage integrity. As such, all steam generator performance criteria were satisfied for Unit 1 Cycle 13. No tube pulls or insitu pressure testing were required based on the results of the examinations.
Tubesheet and Flow Distribution Plate Foreign Object Search and Retrieval (FOSAR) were conducted using a power cart mounted with a remotely operated camera and retrieval tooling. The applicable requirements of the Revision 2 of the EPRI Steam Generator Integrity A4ssessment
Guidelines Section 10.5, Secondary Side Visual Inspections, were applied for the FOSAR inspections. Two (2) pieces of weld wire were identified at the hot leg tubesheet and successfully removed from Steam Generator 12. One (1) of the wires had been observed during eddy current examinations. Plus Point (rotating coil) inspections were subsequently conducted to further verify that no additional piece(s) were present at these locations. The plus point inspections revealed no additional objects. The exams also confirmed no evidence of tube degradation.
As noted in Table 2 there were three (3) possible loose part (PLP) locations identified in Steam Generator 11. The locations arc in areas not accessible by visual exams. Engineering assessment indicated that these locations are in areas of the steam generator where axial flow is dominant and would be less likely to initiate wear. PVNGS has historically taken the position if a loose part is detected by ECT or FOSAR, without the presence of wear, it is reasonable to conclude that the required conditions to promote wear do not exist. The affected and surrounding tubes were inspected with a supplemental and bounding rotating coil examination to confirm that no tube degradation exists. No additional action was required for these locations and the locations will be tracked for future inspection.
Finally, PVNGS Procedure 81DP-9RCOl requires, per the EPRI PWR Steam Generator Examination Guidelines, that a visual inspection of the previously installed steam geneyator plugs be performed to assess plug integrity. Additionally, the Examination Guidelines Section 6.10.1 states - "Verify the location and presence of existing in-service plugs." The conduct of the plug location and integrity verification was performed in UlR13 per procedure 81CP-9RC40. A review of the inspection results indicated that all plugs were accounted for and no evidence of potential plug leakage was identified.
4.0 Examination Results A summary of the bobbin and rotating coil (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 B and C list all tubes in each steam generator with indications expressed as a percent wall thickness reduction, or as an analysis code. Appendix D 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 or the Core Star OMNI 200 instrumentation.
Westinghouse Anser acquisition, software was utilized with both systems. The following frequencies were used for the tube examinations:
Bobbin Coil
- RC.
500 KHz 300 KHz 300 KHz 200 KJ~z 100 KHz 100 KHz 35 KHz 35 KHz
- NOTE: For bobbin coil examinations these frequencies were utilized in both differential and absolute modes.
All tubing was examined with Zetec or Core Star manufactured bobbin coil probes and Zetec RC style probes. Probe diameters were 0.540" to 0.6 10". Plus Point RC probes were used for the characterization of non-quantifiable or distorted bobbin indications. Data acquisition in both steam generators was facilitated by using Westinghouse Pegasys fixtures configured with a dual guide tube in each of the hot and cold legs.
Fiber optic cable was used from containment to the data acquisition room located at the PVNGS North Annex. Primary and secondary analysis was all performed on site. The Primary and Secondary Resolution Analysts, Independent Review Analysts, and data management were also 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 and written examination. All individuals performing data analysis were also required to have Qualified Data Analyst (QDA) certification.
6.0 Repair Techniques and Equipment No repairs were performed as a result of these examinations.
