After evaluating the potential for pieces similar to the loose parts found in 5A HPFWH to reach the Steam Generators, a decision was made 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 Steam Generators. | ||
The following areas were inspected: | 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 gasket material) caused wear on tube R167C84.As a result of the foreign object wear mark that was discovered during FOSAR activities, Eddy Current Testing (ECT) was performed in Steam Generator I during 3R1 7 (documented in Section 5.0). The scope of the ECT included tubes adjacent to the foreign object that was removed as well as four other locations in the cold leg where irretrievable potential foreign objects were noted during the FOSAR inspection. | ||

The | 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 degree angles all of the way around the SG). Approximately 5 tube rows into the bundle were viewed 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 31-15 SG31 FOSAR Results As a result of the inspections performed in SG 31, 17 items were logged as foreign objects. The list of items is included in Table 8-1. Of the 17 items, 3 objects were removed. Two small pieces of tube scale/sludge rocks were removed (Parts 31-1 and 31-2). One piece of metallic material that is believed 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 Part 31-3 was attempted, however, the part was stuck in between tubes and the retrieval attempts were unsuccessful. | ||
Two small pieces | * One object appeared to be a sludge rock (Part 31-4) and attempts to retrieve the object were 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 the initial 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 of the 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 logged as 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 that were inaccessible for more detailed visual inspections. | |||

The list of items is included in Table 8-2. Of the 20 items, 6 objects were removed. One piece of metallic material that is believed to be flexitallic gasket (Part 32-18) was removed. There was no evidence of indications on the tubes surrounding the object. Three small pieces of graphite material were removed from SG 32 (Parts 32-1, 32-3, 32-4). A small sludge rock (Part 32-14) broke apart as it was 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). A Retrieval of Part 32-2 was attempted, however, the part was stuck in between tubes and the retrieval attempts were unsuccessful. | ||
* Part 32-15 appeared to be a small pile of sludge and/or scale and Part 32-17 appeared to be 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 the part could not be located, so the initial inspection most likely showed a reflection in a small amount of water. Parts 32-5, 32-6, 32-7 and 32-8 are extremely small in size (0.05"X0.05"X0.05") | |||
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 | and are suspected to be either reflections of light from a small amount 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 tube plugging 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 be evidence of a mark on tube R167C84, however, since the tube was one row in bundle the view from the annulus could not be definitive. | ||
Tubes in the area of Parts 31-8,31-9, 31-13 and 31-14 were inspected during ECT and no indication of wear | An in-bundle inspection was performed in the area of R167C84 from 2 different angles. The in-bundle inspection revealed a mark on the back side of tube RI 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 the area where the part was retrieved. | ||

DATA SHEETS APPENDIX C -EXAMINATION SCOPE AND HISTORY PLUG MAP 2 of 24 UNIT 3 STEAM GENERATOR EDDY CURRENT U3 R17 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 17th refueling outage in Unit 3 (U3R17) was conducted during November 2013. 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 31 only. The examination plan is listed in Table I and a map with the scope is illustrated in Appendix C. 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 a detailed description.
The plan was developed per PVNGS Procedure 81DP-9RC0I as required by NEI 97-06. In addition, possible damage mechanisms were reviewed along with the specific requirements 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 8.0 contains further discussions relating to this mechanism.
Table 2 summarizes the results into categories and sections B and C itemizes all indications reported.3 of 24 4.0 NDE Techniques Utilized The following table documents the site qualified techniques utilized during this outage: BOBBIN Examination Damage Location ETSS QUAL ORIENTATON BC BC TECH Comment Mechanism NO STATUS DET SIZE Wear BWs, VSs, 96004.1 SITE NA Y Y Volt DIFF None ECs, Rev. 13 QUALIFIED 1 ___ 4-2010 , I Wear Loose Part 27091.2 SITE NA Y N Volt DIFF None Rev. 1 QUALIFIED 8-2007 Rotating Coil Examinations Damage Location ETSS QUAL ORIENTATION RC RC TECH Comment Mechanism NO STATUS DET SIZE BWs, ECs, 96910.1 SITE NA Y Y +POINT None Wear VSs Rev. 10 QUALIFIED 8-2006 I I The eddy current examinations were performed by Westinghouse Electric Company using the Core Star OMNI 200 eddy current instrument.
Westinghouse Anser software was utilized to acquire the data along with the Pegasys robotic manipulator.
This robot was configured with a single guide tube in 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 the characterization of non-quantifiable or distorted bobbin indications.
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.
Per 73T1-9RCO0, all certification records are maintained in the Nuclear Information Records Management System.4 of 24 5.0 Indication Summary A detailed listing of the location and measured sizes of all service induced indications recorded is included in Appendix B and C. A summary of these indication results is located in Table 2. In addition, Appendix A contains a reference drawing of steam generator support locations and report legend.There were no indications that were identified as linear during this outage.6.0 Tubes Plugged There 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 plugged tubes.7.0 Plug History A 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 current examinations are provided in Section 5.0. An engineering evaluation of the as-found condition of in-service 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 3 Cycle 17. 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, Internal Inspection and ECTofthe HPFWH, several metallic parts were discovered in the inlet tube side of the Unit 3 5A High Pressure Feedwater Heater (HPFWH) by Engineering.
Should parts of this type reach the Steam Generator, significant tube damage may occur. After evaluating the potential for pieces similar to the loose parts found in 5A HPFWH to reach the Steam Generators, a decision was made 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 Steam Generators.
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 gasket material) caused wear on tube R167C84.As a result of the foreign object wear mark that was discovered during FOSAR activities, Eddy Current Testing (ECT) was performed in Steam Generator I during 3R1 7 (documented in Section 5.0). The scope of the ECT included tubes adjacent to the foreign object that was removed as well as four other locations in the cold leg where irretrievable potential foreign objects were noted during the FOSAR inspection.
Tubesheet FOSAR was conducted on both SGs using a power cart mounted with a remotely operated 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 degree angles all of the way around the SG). Approximately 5 tube rows into the bundle were viewed 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 31-15 SG31 FOSAR Results As a result of the inspections performed in SG 31, 17 items were logged as foreign objects. The list of items is included in Table 8-1. Of the 17 items, 3 objects were removed. Two small pieces of tube scale/sludge rocks were removed (Parts 31-1 and 31-2). One piece of metallic material that is believed 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 Part 31-3 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 object were 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 the initial 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 of the 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 logged as 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 that were 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 was observed.6 of 24 Table 8-1 SG 31 Foreign Objects Identified ID SG Pat ID Ode DWCl"o EWoo Row Cci Leg Lungt Heigt Widlkh Mdg RuiewW Afamnue Medt T#m Cafwlts n n h ? 7 ID IndGc SG: 31 (17 items)31- 319 003_ 3190 31]/1/0 grpie ts 124 3CL. .125 .375 016 L i 00:12:03 31-00431 31 9D 31020 sludet ft AN6 29 CL 2$1 211 016 [ 0D:D14:2 31- 31 90 1 21/201 Be. ft AN to CL 2 .2$ .0, 00:06:38 002 3 31- 10121/201 003 31 90 Ugrahi tts 124 33 CL 125 .375 116 fl 00:110: 31- 10121/201 004 31 90 3 iudge tts 116 29CL .116 116 .116 L L 00:14:15 31- 31 90 10/213 U2 tts AN1 48CL 4 M2 .02 E F I 00:0D:00 005 3 1 [] ]31- 10121/201 006 3190 3 UFO its 33 6CL .05 .05 105 L 00:04:00 31- 3 rpht tts 53 8 CL 1 1 05 [J00:05:45 3- 31 90 ~101201 UFO its 121 38 CL .116 .116 .116 ~]00:10:23 ove in back 31 3 1 90 1211201 Is 114 33 CL .116 .116 116 2 1700:08:59 one in back 017 319 UFO fl F] F 31- 31 90 101211201 UFO tsB 133 46 CL .116 .116 .116 J [ 00:12-00 Pcsbl2 009 3 piecs 31- 10W211201 ma be g0lket 010 3190 3 UFO tts 165 84 CL 075 075 .075 00] F] 00:17:40 uy 31- 190 211201 319 3 graphite Uts 106 181 CL .116 .15 .116 U U L 00:22:30 31- 390 10121/201 012 31 90 1 graphite Its 102 183 CL .116 .116 .116 El U U 0024:00 31- 190 211201 013 31390 UFO tts 95 178 CL .116 .116 .116 A F] F] 00:27:00 31- 10/21/201 014 31 90 3 UFO Us 134 157 CL .116 ,116 .116 21 U L 00:08:00 31- 90 2t42: 0115 3 0 U 1ST 84 Q. 3 2 .01 M ] 300 .~W36-01 31- 10/21/201 016 31 90 3 UFO Us 135 4a CL .05 .05 .05 A F] E 00:25:00 SG32 FOSAR Results As a result of the inspections performed in SG 32, 20 items were logged as foreign objects. The list of items is included in Table 8-2. Of the 20 items, 6 objects were removed. One piece of metallic material that is believed to be flexitallic gasket (Part 32-18) was removed. There was no evidence of indications on the tubes surrounding the object. Three small pieces of graphite material were removed from SG 32 (Parts 32-1, 32-3, 32-4). A small sludge rock (Part 32-14) broke apart as it was 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). A Retrieval of Part 32-2 was attempted, however, the part was stuck in between tubes and the retrieval attempts were unsuccessful.
- Part 32-15 appeared to be a small pile of sludge and/or scale and Part 32-17 appeared to be 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 the part could not be located, so the initial inspection most likely showed a reflection in a small 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 small amount 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 tube plugging 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 be evidence of a mark on tube R167C84, however, since the tube was one row in bundle the view from the annulus could not be definitive.
An in-bundle inspection was performed in the area of R167C84 from 2 different angles. The in-bundle inspection revealed a mark on the back side of tube RI 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 the area 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 Gasket Figure 8.2 Back side of Tube R167 C84 Wear Scar after Part 31-15 was Retrieved SG 32 No foreign object parts wear was found in this steam generator during FOSAR. Since this was a planned skip cycle and the FOSAR inspection found no evidence of wear, eddy current testing was not performed in SG 32.Potential Loose Parts SG31 There were no reported Potential Loose Parts (PLPs) from the eddy current testing performed in SG 31. Since ECT did not identify wear or even PLP in the area of parts 31-8, 31-9, 31-13 and 31-14, it is reasonable to conclude that the required conditions necessary to produce wear with a significant wear rate do not exist in these locations.
