The steam generator (SG) eddy currentexamination for the 17th refueling outage in Unit 3 (U3R17) was conducted during November2013. Mode 4 entry of Unit 3 Cycle 17 was entered on November 21, 2013. These examinations were conducted due to evidence found during foreign object search and retrieval (FOSAR) in SG 31only. The examination plan is listed in Table I and a map with the scope is illustrated in AppendixC. 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 0 tubes being plugged in SG 31.2.0 Scope of Examinations Performed The original examination plan was developed based on the "PVNGS U3R17 Steam Generator Degradation Assessment" as revised by the evidence of foreign object wear. Note Section 8 for adetailed description.
The plan was developed per PVNGS Procedure 81DP-9RC0I as required byNEI 97-06. In addition, possible damage mechanisms were reviewed along with the specificrequirements set forth in Procedure 73TI-9RCO1 and the PVNGS Technical Specifications.
3.0 Active Degradation Mechanisms The only degradation noted during the examinations was determined to be wear. Section 8.0contains further discussions relating to this mechanism.
Table 2 summarizes the results intocategories and sections B and C itemizes all indications reported.

Westinghouse Anser software was utilized to acquire thedata along with the Pegasys robotic manipulator.
This robot was configured with a single guide tubein SG 31 cold leg.The tubing was examined with Zetec manufactured bobbin coil probes and Zetec rotating coil (RC)style probes. Probe diameters were 0.600" to 0.610". Plus Point RC probes were used for thecharacterization of non-quantifiable or distorted bobbin indications.
Fiber optic cable was used from containment to the data acquisition room located at the PVNGSNorth Annex. Primary and secondary analysis was all performed on site. The Primary andSecondary Resolution
- Analysts, Independent Review Analysts, and data management were alsolocated at PVNGS in the North Annex. Westinghouse provided the data acquisition and primarydata analysis.
Anatec International, Inc. provided the secondary data analysis.
Each individual from Westinghouse and Anatec International, Inc. who performed data analysis wasrequired to complete and pass a PVNGS site specific Eddy Current Data Analysis Course as well asan associated performance and written examination.
All individuals performing data analysis werealso required to have Qualified Data Analyst (QDA) certification.
Per 73T1-9RCO0, all certification records are maintained in the Nuclear Information Records Management System.4 of 24 5.0 Indication SummaryA detailed listing of the location and measured sizes of all service induced indications recorded isincluded in Appendix B and C. A summary of these indication results is located in Table 2. Inaddition, Appendix A contains a reference drawing of steam generator support locations and reportlegend.There were no indications that were identified as linear during this outage.6.0 Tubes PluggedThere were no tubes plugged,
- however, a summary of the total tubes plugged is located in Table 2.Appendix E contains a map that details the plugged tube location along with the previously pluggedtubes.7.0 Plug HistoryA summary of the number and percentage of tubes plugged is also located in Table 2.8.0 Condition Monitoring Per the Steam Generator
- Program, as defined in PVNGS Procedure 81DP-9RCO1, a condition monitoring evaluation was conducted by PVNGS Engineering.
The results of the eddy currentexaminations are provided in Section 5.0. An engineering evaluation of the as-found condition ofin-service tubes did not reveal any degradation exceeding the threshold values for structural andleakage integrity.
As such, all steam generator performance criteria were satisfied for Unit 3 Cycle17. No tube pulls or in-situ pressure testing were required based on the results of the examinations.
Foreign Object Search and Retrieval (FOSAR)On October 9th 2013, during performance of Routine Maintenance Work Order 4197718, InternalInspection and ECTofthe HPFWH, several metallic parts were discovered in the inlet tube side ofthe Unit 3 5A High Pressure Feedwater Heater (HPFWH) by Engineering.
Should parts of this typereach the Steam Generator, significant tube damage may occur. After evaluating the potential forpieces similar to the loose parts found in 5A HPFWH to reach the Steam Generators, a decision wasmade to perform FOSAR activities in both Steam Generators, in which originally no SG inspections were planned.
These FOSAR activities identified and retrieved foreign material from both SteamGenerators.
Steam Generator 2 had no indication of tube wear damage due to foreign material.
Steam Generator 1, however, had visual indications that a metallic foreign object (Flexitallic gasketmaterial) caused wear on tube R167C84.As a result of the foreign object wear mark that was discovered during FOSAR activities, EddyCurrent Testing (ECT) was performed in Steam Generator I during 3R1 7 (documented in Section5.0). The scope of the ECT included tubes adjacent to the foreign object that was removed as wellas four other locations in the cold leg where irretrievable potential foreign objects were notedduring the FOSAR inspection.
Tubesheet FOSAR was conducted on both SGs using a power cart mounted with a remotelyoperated camera, a video probe and retrieval tooling.
The following areas were inspected:
5 of 24 o Hot and cold leg top of tubesheet annulus region (Since Palo Verde SGs have a tri-pitch tube bundle, inspections were performed from the 30 degree, 90 degree and 150 degreeangles all of the way around the SG). Approximately 5 tube rows into the bundle wereviewed from the annulus.o Hot and cold leg blowdown lanes (approximately 2 rows deep was viewed from the lane)o In Bundle Inspection in the area of Part 31-15SG31 FOSAR ResultsAs a result of the inspections performed in SG 31, 17 items were logged as foreign objects.
The listof items is included in Table 8-1. Of the 17 items, 3 objects were removed.
Two small pieces oftube scale/sludge rocks were removed (Parts 31-1 and 31-2). One piece of metallic material that isbelieved to be flexitallic gasket (Part 31-15) was also removed.Of the 14 objects that were not retrieved from SG 3 1:0 4 appear to be graphite material (Parts 31-3, 31-7, 31-11 and 31-12). A retrieval of Part31-3 was attempted,
- however, the part was stuck in between tubes and the retrieval attempts were unsuccessful.
- One object appeared to be a sludge rock (Part 31-4) and attempts to retrieve the objectwere unsuccessful since it was stuck in between two tubes.* One object, Part 31-5 (presumed to be a wire), was identified in the annulus during theinitial inspection,
- however, when retrieval efforts were attempted, the piece was missing.Inspections were re-performed in the entire annulus using both a cart from the wall ofthe wrapper and using a video probe, however, the piece was never found.0 Eight objects were logged as unknown foreign objects (Parts 31-6, 31-8, 31-9, 31-10,31-13, 31-14, 31-16 and 31-17). A review of these objects reveal that what was loggedas Part 31-10 was actually Part 31-15 from a different angle and that part was retrieved.
Three of the unknown foreign objects, Parts 31-6, 31-16 and 31-17, were extremely small parts that appear to be either small sludge rocks or a light reflection in bundle.Parts 31-8, 31-9, 31-13 and 3 1-14 are also small objects located in-bundle in areas thatwere inaccessible for more detailed visual inspections.
Tubes in the area of Parts 31-8,31-9, 31-13 and 31-14 were inspected during ECT and no indication of wear wasobserved.

The listof items is included in Table 8-2. Of the 20 items, 6 objects were removed.
One piece of metallicmaterial that is believed to be flexitallic gasket (Part 32-18) was removed.
There was no evidenceof indications on the tubes surrounding the object. Three small pieces of graphite material wereremoved from SG 32 (Parts 32-1, 32-3, 32-4). A small sludge rock (Part 32-14) broke apart as itwas being retrieved and a very small wire (Part 32-16) was removed from SG 32.Of the 14 objects that were not retrieved from SG 32:* 6 appear to be graphite material (Parts 32-2, 32-9, 32-10, 32-11. 32-19 and 32-20). ARetrieval of Part 32-2 was attempted,
- however, the part was stuck in between tubes andthe retrieval attempts were unsuccessful.
- Part 32-15 appeared to be a small pile of sludge and/or scale and Part 32-17 appeared tobe a sludge rock.* Six objects were logged as unknown foreign objects (Parts 32-5, 32-6, 32-7, 32-8, 32-12,and 32-13). A video probe inspection was performed on parts 32-12 and 32-13 and thepart could not be located, so the initial inspection most likely showed a reflection in asmall amount of water. Parts 32-5, 32-6, 32-7 and 32-8 are extremely small in size(0.05"X0.05"X0.05")
and are suspected to be either reflections of light from a smallamount of water on the tubesheet or a small piece of sludge.7 of 24 All of the parts remaining in the SGs were shown by analysis to be acceptable for a two-cycle SG inspection interval before the potential tube wear degradation reaches the tubeplugging limit and by extension the structural limit.Table 8-2-SG 32 Foreign Objects Identified io SGPut UD Die DmaX EWAND Ru.

After Part 31-15 was removed there appeared to beevidence of a mark on tube R167C84,
- however, since the tube was one row in bundle the view fromthe annulus could not be definitive.
An in-bundle inspection was performed in the area of R167C84from 2 different angles. The in-bundle inspection revealed a mark on the back side of tubeRI 67C84 (Figure 8.2). Eddy current testing was performed in the area of Part 31-15 and confirmed volumetric degradation on three tubes (R167C84; R166C85; R168C85) which were adjacent to thearea where the part was retrieved.
No other wear was discovered in SG 31 during FOSAR inspection or during eddy current testing.8 of 24 Figure 8.1 Part 31-15 before Retrieval-Flexitallic GasketFigure 8.2 Back side of Tube R167 C84 Wear Scar after Part 31-15 was Retrieved SG 32No foreign object parts wear was found in this steam generator during FOSAR. Since this was aplanned skip cycle and the FOSAR inspection found no evidence of wear, eddy current testing wasnot performed in SG 32.Potential Loose PartsSG31There were no reported Potential Loose Parts (PLPs) from the eddy current testing performed in SG31. Since ECT did not identify wear or even PLP in the area of parts 31-8, 31-9, 31-13 and 31-14, itis reasonable to conclude that the required conditions necessary to produce wear with a significant wear rate do not exist in these locations.
