Relief Request #11 CN 001 2.0 Weld #1PZR-W2 2.1. ASME Code Component(s) Affected Unit 1 Pressurizer Spray Nozzle to Upper Head Weld, Weld #1PZR-W2, Summary Number C1..B3.110.0002.

2.2. Applicable Code Edition and Addenda ASME Boiler and Pressure Vessel Code,Section XI, 1998 Edition through the 2000 Addenda 2.3. Applicable Code Requirement IWB-2500, Table IWB-2500-1, Examination Category B-D, Item Number B3.110 Fig. IWB-2500-7 (b), 100% Volume Coverage of Examination Volume A-B-C-D-E-F-G-H 2.4. Impracticality of Compliance

• Surface 1: Upper Head - Carbon steel

• Surface 2: Spray nozzle - Carbon steel

• Diameter: 12.750 in.

• Thickness: 3.000 in.

The ultrasonic examination of this weld obtained 81.7% coverage of the required examination volume. Because of the weld configuration, the requirements of ASME Section V, Article 4, T-441.1.2(a), T-441.1.3, T-441.1.4, T-441.1.5 and T-441.1.6 could not be met. The aggregate coverage was calculated from the following base and weld metal scan results:

Weld coverage using 35°& 450 shear waves for axial scans (S1, S2), and 350 & 450 shear waves for circ. scans (CW, CCW) obtained 91.9%

coverage.

Base material coverage using 35', 450& 600 shear wave for axial scans (SI) and 350& 450 shear waves for circ. scans (CW, CCW) obtained 77.5% coverage.

• 0' scan coverage obtained 75.6% coverage.

• The aggregate coverage was calculated to be (91.9% + 77.5% +

75.6%)/3 = 81.7%.

The limitation was caused by the weld taper configuration created by the attachment of the spray nozzle to the upper head not allowing scanning from Surface 2. In order to scan all of the required volume for this weld, the upper head to spray nozzle attachment weld would have to be redesigned to allow scanning from both sides of the weld, which is impractical.

Relief Request #11 CN 001 The Catawba Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage. The achieved coverage did not meet the acceptance criteria of this Code Case.

2.5. Proposed Alternative and Basis for Use Radiography (RT) is not a desired option because there is no access for film placement.

No other substitution alternative for this weld is available which would provide better coverage.

2.6. Duration of Proposed Alternative This request is for the duration of the third inservice inspection interval, currently scheduled to end on July 15, 2014.

2.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number C1..B3.110.0002 was conducted using personnel, equipment, and procedures qualified in accordance with ASME Section XI, 1998 Edition with the 2000 Addenda.

The system leakage test performed each refueling outage in accordance with Table IWB-2500-1; Examination Category B-P requires a VT-2 visual examination to detect evidence of leakage. This test and VT-2 examination provide additional assurance of pressure boundary integrity.

In addition to the above Code required examinations (volumetric and pressure test), Reactor Building Normal Sump monitoring and other RCS leakage detection systems provide additional assurance that, in the event that leakage did occur through this weld, it would be detected and proper action taken.

Duke has examined the weld/component to the maximum extent possible utilizing approved examination techniques and equipment. Based on the acceptable results for the coverage completed by the volumetric examination, the pressure testing (VT-2) examinations required by Section Xl, and the leakage monitoring, it is Duke's position that the combination of examinations provide a reasonable assurance of quality and safety.

Impracticality of Compliance

• Surface 1: Upper Head - Carbon steel

• Surface 2: Safety/Relief nozzle - Carbon steel

• Diameter: 15.000 in.

• Thickness: 3.000 in.

The ultrasonic examination of this weld obtained 81.2% coverage of the required examination volume. Because of the weld configuration, the requirements of ASME Section V, Article 4, T-441.1.2(a), T-441.1.3, T-441.1.4, T-441.1.5 and T-441.1.6 could not be met. The aggregate coverage was calculated from the following base and weld metal scan results:

Weld coverage using 350 & 450 shear waves for axial scans (S1, S2),

and 350 & 450 shear waves for circ. scans (CW, CCW) obtained 93.0%

coverage.

Base material coverage using 35°, 45°& 60' shear wave for axial scans (51) and 350 & 450 shear waves for circ. scans (CW, CCW) obtained 76.2% coverage.

• 00 scan coverage obtained 74.3% coverage.

• The aggregate coverage was calculated to be (93.0% + 76.2% +

74.3%)/3 = 81.2%.

The limitation was caused by the weld taper configuration created by the attachment of the safety/relief nozzle to the upper head not allowing scanning from Surface 2. In order to scan all of the required volume for this weld, the upper head to safety/relief nozzle attachment weld would have to be redesigned to allow scanning from both sides of the weld, which is impractical.

Applicable Code Requirement IWC-2500, Table IWC-2500-1, Examination Category C-A, Item Number C1.20, Fig. IWC-2500-1 (a), 100% Volume Coverage of Examination Volume A-B-C-D 4.4. Impracticality of Compliance Surface 1: Carbon Steel Flange Surface 2: Stainless Steel Head Diameter: 9.5 inch Thickness: 0.750 inch The ultrasonic examination of the Heat Exchanger head to flange weld obtained 30.6% coverage of the required examination volume. ASME Section XI, Appendix III, 111-4420 requires coverage of the examination volume in two beam path directions and Appendix III, 111-4430 requires scanning on the weld crown in two directions. Due to the presence of nozzles, the scanning was limited in each direction for 50% of the total weld length. The total aggregate percent of coverage was calculated as follows:

Axial scans

• 450 shear waves obtained 0.00% coverage at location of 4 nozzles

• 450 shear waves & 70RL waves obtained 29.7% coverage at remaining length

• Total axial coverage obtained 0.00% + 29.7% = 29.7%

Circ scans

• 45' shear waves obtained 13.2% coverage at location of 4 nozzles

• 450 shear waves obtained 18.2% coverage at remaining length

• Total axial coverage obtained 13.2% + 18.2% = 31.4%

• This aggregate coverage was calculated to be (29.7% + 31.4%) =

61.1%/2 = 30.6%

The limitations were caused by the four physical scanning limitations, all located on the S2 head side. In order to scan all of the required volume for this weld, the heat exchanger would have to be redesigned to allow scanning from both sides of the weld, which is impractical.

Impracticality of Compliance Surface 1: Stainless Steel Shell Surface 2: Stainless Steel Lower Head Diameter: 90.00 inch Thickness: 0.250 inch The ultrasonic examination of the lower head to shell weld obtained 89.4%

coverage of the required examination volume. ASME Section Xl, Appendix Ill, 111-4420 requires coverage of the examination volume in two beam path directions and Appendix III, 111-4430 requires scanning on the weld crown in two directions. Due to the presence four support legs, scanning was limited in each direction for 10.6% of the total weld length. The total aggregate percent of coverage was calculated as follows:

• 450 shear waves obtained 89.4% coverage in one axial direction (S1 -

shell) 0 450 shear waves obtained 89.4% coverage in one axial direction (S2 -

head)

• 450 shear waves obtained 89.4% coverage in one circ. direction (S3 -

CW)

• 450 shear waves obtained 89.4% coverage in one circ. direction (S4 -

CCW)

• This aggregate coverage was calculated to be (89.4% + 89.4% + 89.4% +

89.4%)/4 = 89.4%

The limitations were caused by the four support leg scanning limitations. In order to scan all of the required volume for this weld, the volume control tank would have to be redesigned to allow scanning in each required direction, which is impractical.

5.6. Duration of Proposed Alternative This request is for the duration of the third inservice inspection interval, currently scheduled to end on July 15, 2014.

5.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number C1 .C1.20.0019 was conducted using personnel, equipment, and procedures qualified in accordance with ASME Section Xl, 1998 Edition with the 2000 Addenda.

The system leakage test performed each period in accordance with Table IWC-2500-1; Examination Category C-H requires a VT-2 visual examination to detect evidence of leakage. This test and VT-2 examination provide additional assurance of pressure boundary integrity.

In addition to the above Code required examinations (volumetric and pressure test), periodic visual inspections performed by plant operators provide additional assurance that in the event leakage did occur through this weld, it would be detected and proper action taken.

Duke has examined the weld/component to the maximum extent possible utilizing approved examination techniques and equipment. Based on the acceptable results for the coverage completed by the volumetric examination, the pressure testing (VT-2) examinations required by Section Xl, and the continuing periodic leakage inspections, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety.

Impracticality of Compliance Component configuration:

• Surface 1: Stainless steel elbow

• Surface 2: Stainless steel tee

• Diameter: NPS 4.0 in.

• Thickness: 0.531 in.

Scanning requirements are described in 10CFR.50.55a (b)(2)(xv)(A)(1). The aggregate coverage was calculated from the following:

600 shear waves obtained an aggregate coverage of 64.8% in one axial direction (S1 - elbow) 600 shear waves obtained an aggregate coverage of 50.8% in one axial direction (S2 - tee) 450 shear waves obtained 92.2% coverage in two circ directions on the elbow side (S1).

450 shear waves obtained 100% coverage in two circ directions on the tee side (S2).

The aggregate coverage was calculated to be (64.8% + 50.8% + 92.2% +

100%)/4 = 77.0%.

The limitation was caused by the tee configuration, as well as a pipe running adjacent to the tee side of the weld. In order to scan all of the required volume for this weld, the valve would have to be redesigned, which is impractical.

The Catawba Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage. Therefore, the available coverage will not meet the acceptance criteria of this Code Case.

Relief Request #11 CN 001 6.5. Proposed Alternative and Basis for Use This weld was examined using procedures,, equipment, and personnel qualified in accordance with ASME Section Xl, Appendix VIII. No alternative examinations are planned for the weld during the current inspection interval. Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws. Additionally, radiography has not been qualified through performance demonstration.

6.6. Duration of Proposed Alternative This request is for the duration of the third inservice inspection interval, currently scheduled to end on July 15, 2014.

6.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number C1.C5.21.0002 was conducted using personnel, equipment, and procedures qualified in accordance with ASME Section XI, 1998 Edition with the 2000 Addenda.

coverage. The result from the surface examination was acceptable.

The system leakage test performed each period in accordance with Table IWC-2500-1; Examination Category C-H requires a VT-2 visual examination to detect evidence of leakage. This test and VT-2 examination provide additional assurance of pressure boundary integrity.

In addition to the above Code required examinations (volumetric, surface, and pressure test), Reactor Building Normal Sump monitoring provide additional assurance that, in the event that leakage did occur through this weld, it would be detected and proper action taken.

Duke has examined the weld/component to the maximum extent possible utilizing approved examination techniques and equipment. Based on the acceptable results for the coverage completed by the volumetric examination, the acceptable results of the surface examinations performed during this outage, the pressure testing (VT-2) examinations required by Section Xl, and the leakage monitoring, it is Duke's position that the combination of examinations provide a reasonable assurance of quality and safety.

shell)

• 600 shear and longitudinal waves obtained 45.739% coverage in one circ.

direction (S3 - CW)

• 60' shear and longitudinal waves obtained 45.739% coverage in one circ.

direction (S4 - CCW)

• The aggregate coverage was calculated to be (0% + 20.694% + 45.739%

+ 45.739%)/4 = 28.043%

The limitations were caused by the tubesheet configuration, as well as one nozzle within the weld length. In order to obtain full coverage, the component would have to be redesigned, which is impractical.

The Catawba Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage of examination volume A-B-C-D. The achieved coverage did not meet the acceptance criteria of this Code Case.

Relief Request #11 CN 001 9.0 Weld #1SGD-W261 9.1. ASME Code Component(s) Affected Unit #1 Nozzle to Transition Ring Weld, Weld #1SGD-W261, Summary Number C1.C5.1 1.0001 9.2. Applicable Code Edition and Addenda ASME Boiler and Pressure Vessel Code, Section Xl, 1998 Edition through the 2000 Addenda 9.3. Applicable Code Requirement IWC-2500, Table IWC-2500-1, Examination Category C-F-I, Item Number C5.11 Figure IWC-2500-7(a), 100% Volume Coverage of Examination Volume C-D-E-F 9.4. Impracticality of Compliance Component configuration:

• Surface 1: Inconel Transition Ring

• Surface 2: Carbon Steel Nozzle

• Diameter: 7.5 in.

• Thickness: 1.12 in.

Scanning requirements are described in 1 OCFR.50.55a (b)(2)(xv)(A)(1). The aggregate coverage was calculated from the following:

45* & 600 refracted longitudinal waves obtained 100% coverage in one axial direction (S1 - transition ring) 42* refracted longitudinal waves obtained 37.14% coverage in two circ directions.

The aggregate coverage was calculated to be (100% + 37.14%)/2 =

68.57%.

The limitation was caused by the nozzle taper configuration, which limited coverage in the circ direction only, as Appendix VIII, Supplement 10 demonstrations are qualified for single sided coverage in one axial direction. In order to scan all of the required volume for this weld, the nozzle would have to be redesigned, which is impractical.

The Catawba Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage. Therefore, the available coverage will not meet the acceptance criteria of this Code Case.

Relief Request #11 CN 001 9.5. Proposed Alternative and Basis for Use This weld was examined using procedures, equipment, and personnel qualified in accordance with ASME Section Xl, Appendix VIII. No alternative examinations are planned for the weld during the current inspection interval. Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws. Additionally, radiography has not been qualified through performance demonstration.

9.6. Duration of Proposed Alternative This request is for the duration of the third inservice inspection interval, currently scheduled to end on July 15, 2014.

9.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number C1 .C5.1 1.0001 was conducted using personnel, equipment, and procedures qualified in accordance with ASME Section XI, 1998 Edition with the 2000 Addenda.

In addition to the volumetric examination with limited coverage, Duke performed a surface examination (code required) on this C5.11 item and achieved 100%

coverage. The result from the surface examination was acceptable.

The system leakage test performed each period in accordance with Table IWC-2500-1; Examination Category C-H requires a VT-2 visual examination to detect evidence of leakage. This test and VT-2 examination provide additional assurance of pressure boundary integrity.

In addition to the above Code required examinations (volumetric, surface and pressure test), there are other activities which provide confidence that, in the event that leakage did occur through this weld, it would be detected and proper action taken. Reactor Building Normal Sump rate monitoring provide additional assurance that any leakage would be detected prior to gross failure of the component.

Duke has examined the weld/component to the maximum extent possible utilizing approved examination techniques and equipment. Based on the acceptable results for the coverage completed by the volumetric examination, the acceptable results of the surface examinations performed during this outage, the pressure testing (VT-2) examinations required by Section Xl, and the leakage monitoring it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety.

450 & 600 refracted longitudinal waves obtained 100% coverage in two axial direction (S1 - nozzle, S2 - elbow) 420 refracted longitudinal waves obtained 54.24% coverage in two circ directions.

The aggregate coverage was calculated to be (100% + 54.24%)/2 =

77.12%.

The limitation was caused by the nozzle taper configuration, which limited coverage in the circ directions only. In order to scan all of the required volume for this weld, the nozzle would have to be redesigned, which is impractical.

ASME Section XI, Appendix III, 111-4420 requires coverage of the examination volume in two beam path directions and Appendix III, 111-4430 requires scanning on the weld crown in two directions. The total aggregate percent of coverage was calculated as follows.

• The aggregate coverage from the 0° in the weld and base material obtained 39.440% coverage.

• The aggregate coverage from the 450 shear waves in the weld and base material obtained 49.183% coverage.

• The aggregate coverage from the 350, 600 shear waves in the weld and base material obtained 52.278% coverage.

The total agqreaqate coveraqe obtained was (39.440% + 49.183% + 52.278%)/3 46.967%.

The limitations were caused by the upper lateral support. In order to obtain full coverage, the lateral support would have to be redesigned, which is impractical.

The Catawba Inservice Inspection Plan allows the use of Code Case N-460, which requires greater than 90% volumetric coverage of examination volume A-B-C-D. The achieved coverage did not meet the acceptance criteria of this Code Case.
