Enclosure 1 Response to Request for Additional Information Regarding Watts Bar Nuclear Plant, Unit 2 Request for Approval of a Relief from the American Society of Mechanical Engineers (ASME) Section XI Coverage Examinations for Preservice Inspection (PSI) - Number WBN-2/PSI-1, Revision 1, and Submittal of the Watts Bar Nuclear Plant (WBN) Unit 2 PSI Program Plan, Revision 11 (CAC No. MF8515)) Nuclear Regulatory Commission (NRC) Introduction By letter dated October 5, 2016, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML16293A334) the Tennessee Valley Authority (the licensee), submitted relief request WBN-2/PSI-1, Revision 1, requesting relief from the essentially 100 percent volumetric coverage requirements of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components for the preservice inspections due to access limitations at the Watts Bar Nuclear Plant Unit 2. Specifically, pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(g)(5)(iii), the licensee requested relief from the essentially 100 percent volumetric coverage requirements of ASME Code Section XI for the subject welds on the basis that the code requirement is impractical. The NRC has determined that the following additional information is necessary to complete its review and make a regulatory decision. TVA Introduction During the development of this request for additional information (RAI) response, TVA determined that the reported coverage in the referenced letter for component identifications (IDs) W08-09, WP-11, WP-12, WP-15, SWIFLTR-62-96, and CCPH-2B-B-IA contained errors as noted in the below RAI responses. These errors were entered into the TVA corrective action program and the cause of the errors will be evaluated. The revised PSI reports are included in the enclosures to this RAI response and discussed in further detail in the specific RAI responses. TVA has implemented procedure controls regarding consistency on how coverage is calculated from previous examinations. NRC RAI 1 Regarding component IDs W02-03, N-15, N-16, N-17, N-18, and CCPH-2B-B-IA please provide examination sheets detailing scan diagrams, including the coverage obtained, coverage calculations and obstructions inhibiting further examination. TVA Response: The coverage reports for the components noted in the RAI have been amended to include the requested information and are provided in Enclosure 2. As previously noted, the reported coverage for CCPH-2B-B-IA was recalculated and has been changed from 75 percent (%) to 82.6%. Additional information on this component is provided below. Component ID CCPH-2B-B-IA is four welds that are installed at the four points to the pump case (assembly) ( i.e., one weld at each of the four points) and are welded to the entire perimeter. The pump assembly is bolted to the pump pedestal at these same locations. The intersection of the pump assembly to the pump pedestal does not allow accessibility to CNL-17-091 E1-1 of 9

Enclosure 1 perform examination of the bottom horizontal six inches (in.) of the weld per mounting point (24 in. total) due to opening restrictions of approximately 0.625 to 2.5 in. Gaining access to the weld at this location would require pump assembly removal and subsequent reinstallation of the pump assembly. Therefore, conducting the non-destructive exam (NDE) in place would not provide meaningful results. The quality of a meaningful examination would not be significantly increased if the weld was examined in place without removal of the pump as described above. Enclosure 2 contains a sketch of the exam coverage for CCPH-2B-B-IA. NRC RAI 2 Regarding component IDs W08-09, WP-11, WP-12, WP-13, WP-14, WP-15, please define the directions in items 6 through 9 (e.g. axial out, axial in, transverse clockwise (CW) and counterclockwise (CCW)). Also, please resubmit these figures highlighting the specific examination volume for which coverage was obtained with each scan. Additionally, for the components listed below:

W08 Notes that scan #3 limitation is due to flange and scan #4 limitation is due to lifting lugs however the scan directions are never defined with numbers. Please confirm which directions are associated with these scans. Also, please show graphically where these lifting lugs prevent examination.
WP With two different angles scanning in the same direction with the same geometric obstructions, please explain how the same coverage was obtained for item 7 (direction 2) in both the 60 and 45 degree exams considering the transducers have two different angles but seem to have the same examination limitations. Also, for item 9 (direction 4) of the 0 degree exams, explain what prevented this scan from achieving the same weld length as the other three scans.
WP The 60 degree scan should obtain greater coverage scanning in towards the nozzle than the 45 degree scan. On the other hand, the 45 degree scan should obtain greater coverage than the 60 degree scan when scanning outward away from the nozzle. Therefore, assuming that direction 1 is axial in and direction 2 is axial out for both degree scans, please explain how greater coverage was obtained for the 60 degree scans than for the 45 degree scans in both directions, for items 6 and 7 (directions 1 and 2).
WP Please explain how the same coverage was obtained for item 6 (directions 1) in both the 60 and 45 degree exams considering the transducers have two different angles but seem to have the same examination limitations.

TVA Response The requested information for each of the welds addressed in the RAI is provided below: CNL-17-091 E1-2 of 9

Enclosure 1 Weld W08-09 The following scan directions are defined for W08-09:

Scan 1 is axial from the flange surface.
Scan 2 is axial from the RPV head surface.
Scan 3 is circumferential (clockwise) around the exam volume.
Scan 4 is circumferential (counter clockwise) around the exam volume.

Additionally, the RAI requests TVA to confirm which directions are associated with these scans and to show graphically where these lifting lugs prevent examination. The directions of the scans are as noted above and in the scan direction figure for W08-09 (R-P1014) in . R-P1014 also shows graphically where these lifting lugs prevent examination. As previously noted, the reported coverage for W08-09 was recalculated to reflect the addition of the zero degree coverage and the lifting lug obstructions associated with the 45 and 60 degree scan directions 3 (item 8) and 4 (item 9) (see pages 7, 8, and 9 of RP1014 in Enclosure 3). The initial reported coverage of 75.3% has been changed to 69.3%. The notes the on coverage calculation sheets in Enclosure 3 were changed to reflect the correct values applicable to each examination angle. Weld WP-11 The following scan directions are defined for WP-11:

Scan 1 is radial toward the nozzle.
Scan 2 is radial away from the nozzle.
Scan 3 is circumferential (clockwise) around the exam volume.
Scan 4 is circumferential (counter clockwise) around the exam volume.

The scan direction figure for WP-11 (R-P1283) is provided in Enclosure 3. The calculated coverage for item 7 of the WP-11 coverage report in the referenced letter for the 45 and 60 degree scans performed away from the nozzle was incorrect. Using the scan coverage depicted on page 7 of 15 of the coverage report for R-P1283 in Enclosure 3, the following values were calculated:

60 degree, item 7, exam volume achieved is 7.7 in2, which changes the total value achieved to 305.7 in3 (page 13 of 15 of the coverage report).
45 degree, item 7, exam volume achieved is 4.4 in2, which changes the total value achieved to 174.7 in3 (page 12 of 15 of the coverage report).
The final obtained coverage was revised from 68.73% to 65.72%.
The value of 37.7 in. for the zero degree, item 9, exam volume on page 10 of 10 for R-P1283 in the referenced letter was a typographical error. The value was corrected to 39.7 in. The report presents no description of any scan limitation or obstruction specific to the item 9 scan direction.

The revised coverage report R-P1283 is provided in Enclosure 3. CNL-17-091 E1-3 of 9

Enclosure 1 Weld WP-12 The following scan directions are defined for WP-12:

Scan 1 is radial toward the nozzle.
Scan 2 is radial away from the nozzle.
Scan 3 is circumferential (clockwise) around the exam volume.
Scan 4 is circumferential (counter clockwise) around the exam volume.

The scan direction figure for WP-12 (R-P1282) is provided in Enclosure 3. Additionally, the RAI requests TVA to explain how greater coverage was obtained for the 60 degree scans than for the 45 degree scans in both directions, for items 6 and 7 (directions 1 and 2). Items 6 and 7 for the 45 degree scans and item 6 of the 60 degree scan were calculated corrected correctly. However, the calculated coverage for item 7 for the 60 degree scan performed away from the nozzle was incorrect in page 8 of 10 of the coverage report for R-P1282 in the referenced letter. Using the scan coverage depicted on page 7 of 14 for the revised coverage report for R-P1282 in Enclosure 3, the following values were calculated:

60 degree, item 7, exam volume achieved is 1.575 in2 and the total value achieved is 73.55 in3 (page 12 of 14 of the coverage report).
The final obtained coverage was revised from 60.65% to 55.64%.

Weld WP-13 The following scan directions are defined for WP-13:

Scan 1 is radial toward the nozzle.
Scan 2 is radial away from the nozzle.
Scan 3 is circumferential (clockwise) around the exam volume.
Scan 4 is circumferential (counter clockwise) around the exam volume.

The scan direction figure for WP-13 (R-P1284) is provided in Enclosure 3. Weld WP-14 The following scan directions are defined for WP-14:

Scan 1 is radial toward the nozzle.
Scan 2 is radial away from the nozzle.
Scan 3 is circumferential (clockwise) around the exam volume.
Scan 4 is circumferential (counter clockwise) around the exam volume.

The scan direction figure for WP-14 (R-P1281) is provided in Enclosure 3. Weld WP-15 The following scan directions are defined for WP-15:

Scan 1 is radial toward the nozzle.
Scan 2 is radial away from the nozzle.

CNL-17-091 E1-4 of 9

Enclosure 1

Scan 3 is circumferential (clockwise) around the exam volume.
Scan 4 is circumferential (counter clockwise) around the exam volume.

The scan direction figure for WP-15 (R-P1280) is provided in Enclosure 3. Additionally, the RAI requests TVA to explain how the same coverage was obtained for item 6 (directions 1) in both the 45 and 60 degree exams considering the transducers have two different angles, but seem to have the same examination limitations. Item 6 for the 60 degree scan was correct. However, the calculated coverage for the 45 degree scan performed toward the nozzle was incorrect for item 6 in page 8 of 10 of the coverage report for R-P1280 in the referenced letter. Using the scan coverage depicted on page 8 of 15 for the revised coverage report for R-P1280 in Enclosure 3, the following values were calculated:

45 degree, item 6, exam volume achieved is 10.35 in2 and the total value achieved is 483.34 in3.
The final obtained coverage was revised from 61.22% to 60.4%

Report R-P1280 has been corrected to reflect the adjusted values and obtained coverage. NRC RAI-3 Regarding component ID BIT-2, the rectangle labeled 1 on page 8 of 12 of R-P2183 lies between the 3.25 inch and 2.25 inch measurements corresponding to a width of 1 inch. Additionally, this would correspond to a width of 0.65 inches from the centerline to the near edge of this rectangle. On page 9 of 12, the rectangle labeled 2, which corresponds to rectangle 1 on the previous page, shows a width of 0.5 inches and the width between the rectangle and the weld centerline as 1.15 inches. Lastly, in accordance with figure IWC-2500-1 of ASME Code Section XI, the required examination volume extends half an inch from the end of the weld which would be in line with the measurements on page 9 of 12. Please verify that rectangle 1 on page 8 of 12 is in fact 0.5 inches in width and that the width labeled as 2.25 inches is actually 2.75 inches. Regarding component ID SWIFLTR-62-96, the figure and associated calculations on page 7 of 9 of R-P2373 depict 50% coverage of the ASME code required examination area. The final calculations on that page report 77.75% exam coverage and that is what was reported in Table 1 of the licensees submittal. Please confirm if 50% of the required exam coverage was examined using a qualified procedure and if the reported 77.75% coverage refers to additional exam coverage obtained but cannot be credited due to the qualification of the examinations. TVA Response Rectangle 1 on page 8 of 12 of R-P2183 in the referenced letter is 0.5 in. in width. The 2.25 in. dimension on page 8 of 12 of R-P2183 in the referenced letter should have been 2.75 in., which is reflected in the coverage calculations shown on page 8 of 12 of R-P2183 in the referenced letter. A review of these calculations indicated that the correct value (i.e., 2.75 in.) was used. Enclosure 4 contains the revised coverage for component BIT-2 (drawing R-P2183) to reflect the correct dimension of 2.75 in. Regarding component ID SWIFLTR-62-96, the 50% value shown on page 7 of 9 of R-P2373 in the referenced letter represents the circumferential examination coverage obtained during CNL-17-091 E1-5 of 9

Enclosure 1 the examination. This examination was conducted in accordance with ASME Section XI, 2007 Edition/2008 Addenda, Mandatory Appendix III. The calculated coverage was in error and should have been 75%. The calculations resulting in the obtained coverage of 75% are obtained as follows:

Using 100% calculated examination volume for scan in the axial directions (i.e., 10.298 in3):

o Coverage obtained through the use of bi-directional coverage using the 1/2 Vee and full Vee sound paths in accordance with ASME Section XI, 2007 Edition/2008 Addenda, Mandatory Appendix III, III-4420 (reference page 8 of 9 of R-P2373 in the referenced letter for axial coverage).

Taking 50% calculated examination volume coverage for scan in the circumferential directions (i.e., 5.15 in3):

o One-half of the required examination volume obtained in the clockwise and counterclockwise directions. contains the revised coverage for component SWIFLTR-62-96 (drawing R-P2373) to reflect the corrected values and for clarification of the circumferential and axial scans depictions.

RAI 4

Regarding component IDs BIT-5-IA, BIT-6-IA, BIT-7-IA, BIT-8-IA and CCPH-2B-B-IA, No Recordable Indications was not included in the additional information section. Please confirm whether any recordable indications were identified and if so, provide the details of the dimensions and location. TVA Response There were no recordable indications for the components listed in the RAI.

RAI 5

Provide the weld metals used in the Category B-F, Inspection Item B5.70 Welds. TVA Response The physical component configuration as described in the ASME Section XI Code Table IWB-2500-1, Category B-F, Pressure Retaining Dissimilar Metal Welds in Vessel Nozzles, Inspection Item B5.70 Welds, is steam generator (SG) NPS 4 (DN 100) or larger nozzle-to-safe end butt welds. The configuration of the WBN Unit 2 steam generator (SG) nozzle-to-safe end butt weld joints are not true safe-end welds as described per ASME Section XI Table IWB-2500-1. They are not dissimilar welds, rather, the butt weld joints are stainless-to-stainless made with E308 and ER308 filler metal. Per Westinghouse drawing 1100J81 (sheets 1 and 2), the SG primary nozzles (item 1, Detail A) are ASME SA-216 Gr. WCC buttered with TY308L stainless steel ends welded by Westinghouse. Westinghouse drawing 717J362 (sheets 1 and 2, Detail B) reflect the fabrication of the SG primary side chamber and nozzle. There is also a non-wetted Inconel CNL-17-091 E1-6 of 9

Enclosure 1 ring welded by Westinghouse at the stainless steel buttering to carbon steel nozzle transition shown on these Westinghouse drawings. The TVA field weld is ASME SA-351 Gr. CF8A base material joined to the SG nozzle. TVA welding procedure (DWP) GT-SM88-0-2 was utilized to produce the original field welds. The field weld joints are reflected on TVA drawing SK304-2 series weld maps. The original construction PSI Program for WBN Unit 1 (TI-50A, ASME Section XI Preservice Inspection Program) had the same ASME Category B-F, and TVA component configuration and description (i.e., same Westinghouse Model D3 original SG prior to their replacement in 2006) as WBN Unit 2 currently has installed.

RAI 6

Welds RCF-E1-2-SE, RCF-E2-2-SE, and RCF-E4-2-SE are described as Nozzle to-safe-end welds in Table 1, but are described as Elbow-to-safe-end welds in the respective report numbers R-P2440, R-P2442, and R-P2437. Please clarify the apparent discrepancy, considering all aspects of these welds that are addressed in the submission, including the coverage maps and materials of construction. TVA Response Each of the weld joints are part of the SG primary nozzle to the reactor pressure vessel (RPV) piping. This configuration is detailed on ISI reference drawing ISI-2001-E-01, Revision 3 (Enclosure 6), which depicts the joint configuration in Detail A and shows the joint consists of the piping elbow segment welded to a buttered safe end that is integral to the primary nozzle. Detail A further states THE PIPE TO SAFE END WELD AND SAFE END TO NOZZLE WELD IS IDENTIFIED AS ONE WELD. . . There is no safe end transition segment. The descriptions given in the report can be attributed to the ISI Program descriptor (i.e., RCF-EX-2-SE) and the field configuration (i.e., elbow to nozzle). This configuration is reported by the examiner based upon their field observation. The joint material consists of:

primary nozzle with buttering material (safe end described in ISI-2001-E-01, Detail A)
weld filler material ER-308
piping material SA-351 CF-8A ISI reference drawing ISI-2068-W-01, Revision 4 contained a reference note (i.e., Note 3) for the safe-end weld detail. This Note incorrectly referenced drawing ISI-2068C-03; the Note should have referenced drawing ISI-2001-E-01. Therefore, ISI reference drawing ISI-2068-W-01 has been revised (i.e., Revision 6, see Enclosure 7) to correct this error and has been further enhanced to provide direction to the referenced note.

No recordable indications were detected during this examination. Examination Angles for each probe used with procedure ISwT-PDl-AUT 5 include: PA60°-80°L, PA40°-50°S, PA30°-60°L, & PA0°L. Examination Angles for probe used with procedure ISwT-PDl-AUT-4 include: PA6°- 40°L, PA35°-45S. Exam #50 was divided into sections A - D (sections C & D were additional exams using specfic probes for improved examination coverage). The examination was limited due to the proximity of the nozzle intregral extension. The examination coverage was 84%. \'--l ~ w*~Ltt u...> a..~ e')LQ...l°"<'-t n..:& ~roM- lli- {'~-Z'2.-l lf'\S.l.,t,.::. s<.4. +:c..c 41' LL<:>( I..::>\ Pt \J'\ !, -c- -l\\ ~.rio-"C*c:.~ e~:fL*"- ~~.o..:-\ . \l).tr' Ld L*,;;- - 1 Reviewed rYi Signature: ~ - Tennessee Valley Aut t(

RAl-1 DISCUSSION: Reference Dwg ISl-2062A* E- 01 and Vendor (Dresser/Pacific Pumps) Dwg FC-48590 ISi Report No. R* P3950 The 2B Centrifugal Charging Pump integral attachment (IA) welds (component identifier CCPH*2B*B*IA) are Installed and mounted at 4 points to the pump case (assembly) and are welded their entire perimeter. The pump assembly is bolted down to the pump pedestal at these same locations. The intersection of the pump assembly to the pump pedestal does not allow accessibility to perform examination of the bottom horizontal 6 inches of the weld per mounting point (24 inches total) due to opening restrictions of approximately 0.625 to 2.5 inches. To gain access to the weld at this location would require pump assembly removal and subsequent reinstallation from and to the pump pedestal that would require extensive operations, maintenance, and plant support. To conduct the NOE exam in place would be difficult to perform and would not be a meaningful exam due to the weld access. The quality of a meaningful examination would not be significantly increased if the weld was examined in place without remova l of the pump as described above. COVERAGE CALCULATION: The weld surface is approximately 1.5 inches wide. An additional 1 inch is added for the 1/2 inch of 1 component base metal on each side within the exam boundary. Total coverage is 2.5 in per linear inch. The outboard weld length is 35 and 35 inches per individual mounting point (70 Inches combined for both outboard attachments). The inboard weld length is 35 and 33 inches per Individual mounting point (68 inches combined for both inboard attachments).
=
The overall weld length is 138 inches (total for all 4 mounting points comblned). (70 + 68 138)
=
Subtract 24 inches (6 inches per mounting point) from the overall weld length (138
24 114)
The IA weld length acquired exam coverage is 82.6 percent (114 -+ 138 =.8260) x 100 =82.6. This is greater t han what was initially estimated at 75 per cent.
=
The overall surface coverage is 138 x 2.5 in2 345 ln 2 The accessible surface coverage is 114 x 2.5 in2 = 285 in 2 The acquired surface coverage is 82 .6 per cent (285 + 345 = .8260) x 100 = 82.6 See attached sketch for exam coverage.

W P With two different angles scanning in the same direction with the same geometric obstructions. please explain how the same coverage was obtained for item 7 (direction 2) in both the 60 and 45 degree exams considering the transducers have two different angles but seem to have the same examination limitations. Also. for item 9 (direction 4) of the O degree exams, explain what prevented this scan from ach ieving the same weld length as the other three scans.

The calculated coverage for both the 45 and 60 degree scan performed away from the nozzle are incorrect (calculation sheet rtem 7) . Using the scan coverage depicted on page 7 of R-P1283, the following values were calculated.

60 degree, item 7, exam volume achieved is 7.7" sq uare (page 8}.

o Changes total value achieved t o 305.7 cubic inches.

45 degree, item 7, exam volume achieved fs4.4 sq uare (page 9}.

o Changes total value achieved to 174.7 cubic inches.

o degree value reported on page 9 is a typo. The report presents no description of any scan limitation or obstruction specific to th e item 9 scan direction.

Changes final obtained coverage from 68 .73% to 65 .72%.

Report R-Pl283 has been corrected to reflect the adj usted values and obtained coverage.

This report was amended due to NRC RAls associated with Relief Request WBN-1/PSl-1 Revision 1 and RAl-2 . Reference CR: / "? OCf~ 11 Report: R-P1282/WP-12 Coverage changed to 55 .64%. 60degree coverage worksheet changed.

WP T he 60 degree sca n should obtain greater coverage scanning in towards the nozzle than the 45 degree scan. On the other hand . the 45 degree scan should obtain greater coverage than the 60 degree scan when scanning outward away from the nozzle. Therefore, assuming that direction 1 is axial in and direction 2 is axial out for both degree scans, please explain how greater coverage was obtained for the 60 degree scans than for the 45 degree scans in both directions. for items 6 and 7 (directions 1 and 2).

The calculated coverage forthe 60 degree scan performed away from the nozzle is incorrect (calculation sheet item 8}. Using t he scan coverage depicted on page 7 of R-P1282, the fo llowing values were calculated.

60 degree, item 7, exam volume achieved is 1.575"square.

o Changes the total value achieved to 73.55 cubic inches. o Changes f in al obtained coverage from 60.65% to 55.54%

WP Please exp lain how the same coverage was obtai ned for item 6 (directions 1) in both the 60 and 45 degree exams considering the transducers have two diffe rent angles but seem to have the same examination limitations.
The calculated coverage for the 45 degree scan performed toward t he nozzle is incorrect (calcu lation sheet item 6). Using the scan coverage depicted on page 8 of R-Pl280, the fo llowing values we re calculated.
45 degree, item 6, exam volume achieved is 10.35" square .
o Changes the total value achieved to 483.34 cubic inches. o Changes final obtained coverage from 61.22% to 60.4% Report R-P1280 has been corrected t o ref lect the adjusted values and obtained coverage.

This report was a'T1ended due to NRC RAls associated with Relief Request WBN-1/PS l-1 Revision 1. t-¥/ufr? Reference CR:~ /'~O.tf'z5l1 Report: R-P2183/BIT-2 Corrected dimension on page 8. Regarding component ID BIT-2, the rectangle labeled 1 on page 8of 12 of R-P2183 lies between the 3.25 inch and 2.25 inch measurements corresponding to a width of 1 inch. Additionally, this would correspond to a width of 0.65 inches from the centerline to the near edge of this rectangle. On page 9 of 12, the rectangle labeled 2, which corresponds to rectangle 1 on the previous page, shows a width of 0.5 inches and the width between the rectangle and the weld centerline as 1.15 inches. Lastl y, in accordance with figure IWC-2500-1 of ASME Code Section XI, the required examination volume extends half an inch from the end of the weld which wou ld be in line with the measurements on page 9 of 12. Please verify that rectangle 1 on page 8 of 12 is in fact 0.5 inches in width and that the width labeled as 2.25 inches is actually 2.75 inches. The 2.25" dimension on page 9of12 described above is incorrect. The correct dimension should be 2.75" and measures as such. This is supported through the coverage calcu lations show n on the referenced page. Review of these calculations show the correct value was used. The report will be corrected to reflect the correct dimension of 2.75" .

This report was amended due to NRC RAls associated with Relief Request WBN-1/PSl-1 Revision 1. Reference CR: / 'f;oq ~I 1 Report: R-P2373/SWFILTR-62-96 Changed coverage to 75%. Amended pages 7 and 8. Regarding component ID SWIFLTR-62-96 , the figure and associated calculations on page 7 of 9 of R-P2373 depict 50% coverage of the ASME code required examination area. The final calculations on that page report 77.75% exam coverage and that is what was reported in Table 1 of the licensee's submittal. Please confirm if 50% of the req uired exam coverage was examined using a qualified procedure and if the reported 77.75% coverage refers to additional exam coverage obtained but cannot be credited due to the qualification of the examinations. Io t-11fto/i1 The 50% value shown on page 7 ofJ represents the circumferential examination coverage obtained during the examination. This examination was conducted in accordance with ASME Section XI, 2007 Edition/2008 Addenda, Mandatory Appendix Ill. The calculated coverage provided is in error. Actual coverage should be 75%. The calculations resulting in the obtained coverage of 75% are obtained as follows:

NPG MANUAL ULTRASONIC EXAMINATION OF N-UT-33 Nondestructive STATIC AND CENTRIFUGALLY CAST Rev. 0013 Examination STAINLESS STEEL PIPING WELDS Page 7 of 14 Procedure 5.0 BASIC CALIBRATION BLOCKS (continued) NOTE Where the examination is to be performed from only one side of the joint, the calibration block material shall be of the same specification as the material on that side of the joint.

4. Surface finish of the block shall be representative of the surface finish on the component to be examined.

5. Basic calibration blocks shall contain circumferential and longitudinal notches whose sides are perpendicular to the surface, at least 1.0 in. long, on the ID surface with a depth of 10% t. Block design shall generally conform to the design shown in Reference 2.0C.

6.0 CALIBRATION A. Instrument Calibration

1. Instrument calibration for screen height and amplitude control linearity shall be verified and recorded at the beginning and end of the weld examinations performed during one outage. The technique for evaluating screen height and amplitude control linearity is contained in Reference 2.0C.

2. Reject of clipping controls shall be set in the off or minimum position for calibration and examination.

B. System Calibration

1. General Requirements

a. Calibration shall include the complete ultrasonic examination system. Any change in search units, shoes, couplants, cables, ultrasonic instruments, recording devices, or other parts of the examination system shall be cause for calibration check. The original calibration shall be performed on the basic calibration block. Calibration checks may be performed on either the basic calibration block or a simulator block, but must include a check of the entire examination system.

b. The maximum calibration indications shall be obtained with the sound beam oriented essentially perpendicular to the axis of the calibration reflector. The centerline of the search unit shall be as least 3/4 inch (19 mm) from the nearest side of the block or pipe. Block corner (edge) reflectors shall not be used for calibration.

c. Complete ultrasonic examination system calibration shall be performed within one day prior to use of the system for examination of those welds for which the calibration is applicable, and at least once each week during the examination.

NPG MANUAL ULTRASONIC EXAMINATION OF N-UT-33 Nondestructive STATIC AND CENTRIFUGALLY CAST Rev. 0013 Examination STAINLESS STEEL PIPING WELDS Page 8 of 14 Procedure 6.0 CALIBRATION (continued)

d. The temperature difference between the examination and basic calibration block surfaces shall not exceed 25-degrees F. The temperature of the calibration block and the component temperature shall not exceed 125-degrees F. The calibration block temperature shall be recorded on the ultrasonic calibration data sheet.

e. Obtain the angle beam paths as required to detect reflectors parallel and transverse to the weld per paragraphs 7.0F1 and 7.0F2 respectively, on the sweep display. Variables such as weld preparation, weld crown width, or physical interference may preclude obtaining two beam path direction coverage of the complete examination volume with half-V examination from two sides.

NOTE Interference may be eliminated or reduced by: 1) reducing the dimension of the wedge edge-to-beam entry point; 2) reducing search unit size; 3) increasing the beam angle; 4) conditioning the weld surface. C. System Calibration Checks A system calibration check, which is the verification of the instrument sensitivity and sweep range calibration, shall be performed:

1. at the start and finish of each examination;

2. at intervals not to exceed 12 hours;

3. With any change in examination personnel, except when using automated equipment

4. An unsatisfactory system calibration check requires corrective action as identified in Reference 2.0C.

D. Angle Beam Sweep Reference Sensitivity Calibration As a minimum, a 45-degree (+/- 3 degrees) nominal refracted longitudinal wave examination shall be conducted; other angles may be utilized to enhance the examination process. The search unit beam exit point shall be determined and the beam angle shall be measured using the basic calibration block.

1. Sweep

a. Position the search unit on a reference block or the basic calibration block.

Maximize the responses from the applicable reflectors. Adjust these responses on the screen to represent the desired linear sound path in inches.
NPG MANUAL ULTRASONIC EXAMINATION OF N-UT-33 Nondestructive STATIC AND CENTRIFUGALLY CAST Rev. 0013 Examination STAINLESS STEEL PIPING WELDS Page 9 of 14 Procedure 6.0 CALIBRATION (continued)

b. The desired linear sound path shall be such that the ID notch reflector is displayed at approximately five horizontal screen divisions on the screen.

Record the calculated screen range.

2. Reference Sensitivity

a. Primary reference sensitivity is established by setting the maximum response to 80% FSH from the circumferential ID notch for an axial scan.

b. Primary reference sensitivity is established by setting the maximum response to 80% FSH from the axial ID notch for a circumferential scan.

7.0 EXAMINATION A. Preliminary Requirements

1. Surface Condition

a. Examination surfaces shall be free of irregularities, loose foreign material, or coatings which interfere with sound transmission to the point of test degradation. The weld crown should be ground flush where practical to provide adequate search unit coupling for maximum examination coverage.

b. Thickness measurements and ID/OD profiles should be performed on each weld prior to examination. This information shall be recorded on the wall thickness profile sheet.

B. Scanning Sensitivity Scanning shall be performed, as a minimum, at twice the primary reference sensitivity (+6 dB) unless test variables beyond the control of the operator, e.g., material noise levels causing signal-to-noise ratios of less than two, preclude meaningful results. In general, a material noise level of 10-25 percent is optimum for proper sensitivity adjustment. In no case shall the average baseline noise level exceed 30 percent FSH and shall not be less than 10 percent FSH. C. Scanning Speed Scanning speed shall not exceed three inches per second. D. Scan Path Overlap The required examination volume shall be scanned with beam overlap. While scanning, the search unit shall be oscillated approximately + 20 deg. If oscillation is not possible, the search unit shall be overlapped at least 50%.

Pulsers, receivers, or search units may be replaced without re-qualification provided that they meet the requirements of ASME Section XI, Appendix VIII, and Article 4000. Additionally, replacement phased array probes shall also meet the requirements of Procedure 7.0-NDES-003, "Receiving Inspection of Phased Array Probes." This procedure contains additional receipt inspection processes and shall be used for acceptance of new replacement phased array probes.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 7 of 29 5.0 SYSTEM OPERATION 5.1 Master Acquisition Files The master acquisition files listed below shall be used to establish the T-III operational settings during the PDI qualification process and subsequent field examinations. These master acquisition files contain the software settings that control the system operation. These files shall be controlled under ISwT OP 11.0-NDES-001. DM_Pipe_ID_0_CW_180_CCW_Skew.acq DM_Pipe_ID_90_AWY_270_TWD_Skew.acq 5.2 Phased Array Probe Active Element Verification After equipment setup and prior to and after a series of examinations, an active element verification shall be performed on each phased array probe. The element check files, 1-128-elementcheck01.acq shall be loaded. The file will display the UT responses for TOMO_III pulser-receivers 1-128 and indicate the performance of each element. The elements in each array shall be verified as follows: (1) The uncorrected sectorial scan should now display all 128 elements associated with this file; however, only 44 elements will display evidence of ultrasound activity from the search unit wedge because only two probes can be connected at any one time. (2) The examiner shall manually dampen each side of the array (transmit/receive) to assure the cables are connected properly. If the examiner dampens the transmit side of the array, the responses from transmitting elements shall also dampen. This same process shall be performed for the receiving elements. If the responses are reversed, this indicates that the probe or cable connector has been wired incorrectly and the affected component shall not be used. (3) Place the probe on a block with a known reflector. Move the probe over the reflector such as to encompass the reflector's echo dynamic range. Adjust the gain as necessary to assure adequate response for each element without signal saturation. Each element should demonstrate echo-dynamics. Observe the UT signal characteristics from each element, on the uncorrected sectorial scan plane and A-Scan presentations. A non-active element will appear similar to focal laws 65 through 128 which is the bank of elements not used and will demonstrate no echo-dynamics. (If more than two non-active elements are observed on an individual transmitting or receiving array, then the probe shall be replaced. In addition, the examiner shall identify any elements that appear to have a reduced signal response as compared to the other elements within the array. Elements that are noted to have a 6 dB reduction in amplitude from the adjacent elements in general area of the wedge (similar metal path to wedge interface) shall be considered inactive.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 8 of 29 (4) The active element checks shall be documented on the calibration record. 5.3 Ultrasonic Linearity Measurements Prior to system sensitivity performance verification, screen height and amplitude control linearity shall be performed in accordance with ISwT OP ISwT-NDE2, "Ultrasonic Linearity Measurements." 5.4 Search Unit Exit Point and Angle Verification The master PDI acquisition file shall be used for measuring the actual refracted angle. A reference block in accordance with Paragraph 4.5 shall be used. (1) Load the appropriate data acquisition file. The file will display the ultrasonic responses for each focal law. Select the 60° focal law for verification. (2) Maximize the signal from the 4.0 or 1.0-inch radius using the 60° focal law and set each response to 80% +/- 5% FSH. (3) Mark the exit point on the probe casing for each angle. (4) Measure the refracted angle for each focal law. (5) The refracted angle shall be within 3 degrees of focal law selected or the probe shall be replaced. 5.5 Initial Time Base Verification Prior to examination, initial time base performance verification shall be performed on a reference block reflector within examination area. A 60 º focal law shall be used to determine the required time base in both the axial and circumferential direction utilizing the criterion specified below: The minimum time base shall encompass the code volume in depth. The maximum time base shall be the anticipated thickness of the component for circumferential flaw detection scanning. The maximum time base shall be 2.0 inches in true depth for transverse flaw detection scanning. The examiner shall perform adjustments in order to establish the system delay using instructions.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 9 of 29 (1) Set the receiver scale type to linear and the time base mode set to half path. (2) The 60° focal law shall be used to establish system delay. (3) Maximize the amplitude from the 4.0" radius and adjust the amplitude response to between 50% and 80% FSH. (4) Adjust the probe delay until the system digital readout corresponds as 4.0". Slight variations in the read out are allowed within the A-Scan resolution of the system. Document the channel gain, metal path, and amplitude on the calibration record for each focal law. (5) Set the receiver scale type to "Log" and reset the channel gain to zero. (6) Re-measure the metal path and maximum amplitude from the 4.0"radius and record it on the calibration data sheet. This accounts for the system delay changes realized from the two different amplifiers. The recorded metal path distance, amplitude, and gain measured in this step shall be used as the basis for subsequent system performance verifications and is also the reference sensitivity for the examination. (7) The Data Analyst shall review the measurements taken in steps 3 - 6 for accuracy. The Data Analyst shall adjust the settings as required. 5.6 Initial 0° Immersion Profilemetry Time Base and Amplitude Verification (1) The verification shall first be performed in the "Log" mode, full screen height and in true depth. The 0° time base range shall be set to a minimum range of 3.0 inches in depth. It may be necessary to recycle the In Wedge field in the Probe Tab for accurate range and A-scan scale correlation. (2) The 0° immersion probe shall be mounted in a 1.5 inch stand off module and placed on the calibration reference block. (3) The measured time to the first entry surface reflection shall be 1.5 inches. The "Wedge Delay" shall be adjusted as required to read 1.5 inches. The gain setting, metal path distance (measured in depth), and amplitude shall be documented on the calibration record. (4) The Data Analyst shall review the measurements taken in above steps for accuracy. The Data Analyst shall adjust the settings as required.

(3) If it is determined that the loss of sensitivity is attributed to failure of more than 2 receiving or 2 pulsing elements (or any other system parameter), then the data recorded since the last valid verification shall be re-evaluated by the Data Analyst in an attempt to determine when the loss in sensitivity occurred.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 14 of 29 (4) If the Data Analyst can determine when the change in system sensitivity occurred and that the data recorded prior to that change has adequate sensitivity (within 7 dB of reference), that data shall be accepted. (5) If the Data Analyst determines that any portion of the data recorded since the last valid sensitivity verification did not have adequate sensitivity (within 7 db of reference), the data shall be voided, the system sensitivity shall be corrected, and the affected areas shall be reexamined. 6.6 Supplemental Examinations Supplemental examinations with different equipment and or instrument settings may be performed in order to facilitate evaluation or analysis of the data. The results of supplemental examinations may not be used to overturn the results obtained with the primary qualified techniques or be used to claim additional coverage. 7.0 DATA ANALYSIS FOR FLAW DETECTION AND LENGTH SIZING 7.1 Pre-Analysis Verification Prior to analyzing data, the Data Analyst shall ensure the quality of the data by verifying the following: (1) Load data and apply the ISwT_DM_Detection.rst. This .rst file contains the appropriate layouts and measurement tools to perform the data quality checks and length sizing measurements. (2) Ensure all volume corrected views are in the projection mode and not linked. (3) Activate each pane and ensure that all measurement units are set to inches, with two decimal places of precision and the Usound is set to "True Depth." (4) Under the pane "Edit Panes Properties" icon select the "parameters" tab and verify that all parameter inputs are correct (sound velocity, delay, offsets, skew angles, etc.). (5) In all the volume corrected displays adjust the cursors to envelop the entire scan area. (6) Adjust the amplitude color palette range to provide resolution of the various reflectors throughout the scan in order to provide optimum image contrast and ensure that the flaw(s) are not masked with the background noise.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 15 of 29 (7) After evaluating the overall examination data quality adjust the gates to display specific regions of the weld length or volume that contains the indications or geometric reflectors, if any. (8) For each channel, analyze the volumetric images to observe the echo dynamic patterns from the VC (D) and VC (B) panes to determine that sufficient data is available to perform analysis. (9) Ensure all data has been collected in accordance with requirements of this procedure and all the essential variables have been verified. (10) Ensure all required examinations have been performed and scan limitations documented. (11) Ensure the necessary data records and required scan area per the examination plan specified in 6.1 has been covered. (12) The 0° profilometry data, thickness, contours, and previous data shall be utilized in the evaluation of the data. (13) Ensure adequate search unit contact has been achieved. Isolated instances of lack of contact may be accepted provided that no more than 2 adjacent acquisition positions are void of data and the area does not contain flaws or suspected flaw indications that require evaluation. (14) The Overall data quality shall be evaluated as described above, in addition to these requirements the data must be free from internal system or external noise in the data that may have a detrimental effect on this procedures flaw detection and sizing capabilities (15) Areas that do not meet the acceptance criteria stated above shall be reexamined and evaluated to the requirements of this section. If a second examination does not achieve acceptable data, the amount of missed coverage shall be documented as a limitation and reported to the customer. (16) The necessary data records and required scan area per the examination plan specified in 6.0 has been covered.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 16 of 29 7.2 Data Analysis (1) Load the appropriate data file. (2) Load the ISwT_DM_Detection.rst ISwT_DM_Detection.rst The "ISwT_DM_Detection.rst" file provides real time dual channel correlation for flaws and or geometric benchmarks and should be used when analyzing merged data. (3) Ensure that each channel has been fully merged. (4) In all the volume corrected displays adjust the cursors to envelop the entire scan area. (5) Adjust the amplitude color palette range to provide resolution of the various reflectors throughout the scan in order to provide optimum image contrast and ensure that indications are not masked with the background noise. (6) After evaluating the overall examination for areas that exhibit deviation from the component geometrical or metallurgical interface responses adjust the gates to display specific regions of the weld length or volume for further pattern interpretation.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 17 of 29 (7) For each channel, analyze the volumetric images to identify areas that exhibit deviation from the component geometrical or metallurgical interface responses. Only patterns from the VC Top (C) pane that exhibit echo-dynamics in the VC (B) pane shall be considered flaw. The following conditions should be considered for classification of flaw versus geometrical indications. 7.3 Discrimination of Geometric Benchmarks All suspect indications, regardless of amplitude, shall be investigated to the extent necessary to determine accurate characterization of the nature of the indication. The 0° profilemetry data, thickness, contours and previous data may be utilized in analyzing the detection data. Indications that are determined to originate from surface configurations or variations in metallurgical structure of materials may be classified as geometric indications. Such indications need not be characterized as originating from flaws and flaw sizing and comparison of reflector causing the indication with the allowable flaw standards of IWA-3000 is not required. The location of the reflector causing a geometric indication shall be recorded. The following conditions shall be considered for determination of geometric indications due to surface conditions and/or metallurgical conditions. (1) The indication can be seen across the entire length of the scan (either continuously or intermittently) at consistent amplitude and position responses. (2) The indication possesses very little or no echo dynamic travel in the depth direction. (3) The indication appears at or near one of the weld acoustic interfaces. (4) Similar indications can be seen at varying amplitudes along the weld length intermittently. 7.4 Discrimination of Flaws The following conditions shall be considered for determination of flaw indications: (1) The indication has a high signal-to-noise ratio. Raising the upper and lower amplitude thresholds of the color palette and observing signal-to-noise ratio contrast across the length of the component can support this. (2) The indication response is isolated from, or exhibits greater echo dynamics than, common geometrical benchmark responses identified in 7.3. (3) The indication has defined start and end points.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 18 of 29 (4) The indication possesses echo dynamic responses indicating reflector depth. Due to flaw orientation this information may be displayed as a significant pattern of response displayed below inside surface. (5) The indication can be confirmed from the opposite direction. (6) The indication response is repeatable during additional or supplemental scans. (7) It may be necessary to zoom the area of interest in the VC Top View display achieve sufficient resolution of flaw locations. (8) In areas of lift-off or geometric benchmarks, it may also be necessary to scroll through the individual scan rows using the "Single Plane", linked to Ref. Cursor" option in the "Echo Dynamics" tab. 7.5 Flaw Location (1) After a flaw has been identified, the X and Y locations of the flaw shall be determined as follows: (a) Axial Flaws Y Location = ((Y2 - Y1) / 2) +Y1 (b) Axial Flaws Y Location = Y Max Amplitude (c) Axial Flaws (Oriented) X Location = ((X2 - X1) / 2) + X1 (d) Circumferential Flaws X Location = ((X2 - X1) / 2) + X1 (e) Circumferential Flaws Y Location = Y Max Amplitude (f) Circumferential Flaws (Oriented) Y Location = ((Y2 - Y1) / 2) + Y1 (2) For axial flaws, a hysteresis correction shall be applied to locate the flaw at the proper Y- location. (3) If the flaw is only observable from one direction, the location coordinates shall be determined from that observation. (4) If the flaw is observable from two opposite directions, the flaw location coordinates shall be determined using an average from both observations. 7.6 DATA ANALYSIS FOR LENGTH SIZING (1) Initial Length measurements may be obtained using the A-scan, the volume corrected (VC)-side (B-scan), VC -Top (C-scan) and the VC-End (D-scan) views. Length sizing shall be performed using the vertical or horizontal echo-dynamic curve histograms. The "Slice between Reference and Measure Cursors" shall be selected under the echo-dynamics tab. The flaw shall be completely bound using the Reference and Measure Cursors.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 19 of 29 (2) Length Final Length measurements shall be determined by measuring the 1/4 max points as determined by the; horizontal histogram associated with the VC-Top (C-Scan) view with a full merge of angles 60° through 88° for circumferential flaws, and vertical histogram associated with the VC-Top (C-Scan) view with a full merge of angles 60° through 88° for axial flaws. (3) If the flaw is observable from two opposite directions, the flaw length measurement shall be the longer of the two measurements. 7.7 DEPTH SIZING Depth sizing of inside surface connected flaws shall be performed in accordance with procedure ISwT-PDI-UT-12, "Automated Inside Surface Ultrasonic Flaw Depth Sizing of Piping Welds Using Phased Array" (Latest Revision). 7.8 Embedded Flaws (1) This procedure has not been demonstrated to detect or size embedded flaws, which are considered fabrication related. However, indications such as lack of fusion or slag inclusions may be detected with this procedure. When significant fabrication flaws are detected and where they appear to have measurable dimension an estimate of flaw size will be made and reported using the data collected with this procedure. (2) Using the data collected with this procedure evaluate the flaw to determine if the flaw exhibits planar characteristics the height of the flaw will be estimated with tip diffraction techniques. The examiner must determine which zone (Lower 1/3, Middle 1/3, or Upper 1/3) the embedded flaw is located. Once this zone is determined the focal law that resolves the flaw extremities the best shall be used for the measurement. If additional data is required supplemental data taken in accordance with procedure ISwT-PDI-UT-12 may be applied. (3) If the flaw exhibits volumetric characteristic, but no tip signals are observed the height of the flaw will be estimated using the 6dB drop method. (4) The length of the flaw will be estimated at the level at which it is detectable above the noise level.
IHI Southwest Technologies, Inc. ISwT-PDI-AUT11 Rev. 1, Chg. 0 Operating Procedures Page 20 of 29 8.0 EXAMINATION DATA RECORD(S) All data within the specified examination volume shall be recorded using the UltraVision software regardless of time and amplitude.
