Enclosure to ONS-2015-086 Duke Energy Carolinas, LLC Oconee Nuclear Station, Units 1 and 2 Relief Request Serial #15-0N-002:
Limited volume examinations per 10 CFR 50.55a(g)(5)(iii) for Unit 1 and 2, Fourth lnservice Inspection Interval Oconee Relief Request 15-0N-002 1.0 Scope of Relief Request Relief is requested pursuant to 10 CFR 50.55a(g)(5)(iii) for welds listed in Table 1. These welds were required to be examined in accordance with lnservice Inspection Plans for the following Units. Oconee Nuclear Station -Unit 1 Fourth 10-Year lnservice Inspection Interval Interval Start Date: January 1, 2004 Interval End Date: July 15, 2014 Table 1 Relief Oconee Examination Weld ID Number ltem/Summarv Examination Request Unit Performed Number Data -Section Number (Refueling Number Outage} 2.0 1 1EOC27 1-RPV-WR34 01.81 .11.0005 See Attachment A Pages 1-2 3.0 1 1EOC27 1-RPV-WR35 01.81 .21.0001 See Attachment A Pages 3-8 4.0 1 1EOC27 1 LDC8-INLET 01.82.51.0003 See Attachment A Pages 9-21 5.0 1 1EOC27 1 LDCB-OUTLET 01.82.51.0004 See Attachment A Pages 22-34 6.0 1 1EOC27 1-PDA1-1 01.89.11.0059 See Attachment A Pages 35-44 Note: 1. Duke Energy procedures require ASME Code,Section XI examinations that do not meet the requirements of Code Case N-460 to be marked "reject" for tracking purposes, regardless of whether indications were noted. Therefore, the limited exams in 15-0N-002 without indications were marked "reject" on data sheets. 2. Duke Energy has invoked Code Case N-663 which allows elimination of Code required surface exams for welds listed in Section 6.0 of this Relief Request. Page 1 of31 ----*-***
Oconee Relief Request 15-0N-002 2.0 Weld # 1-RPV-WR34 2.1. ASME Code Component(s)
Affected Unit 1 Reactor Vessel Lower Shell Course to Lower Ring Section Weld, Reactor Coolant System, Weld # 1-RPV-WR34, Summary Number 01.81 .11.0005, and ASME Code Class 1. 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-A, Item Number 81 .11 Fig. IWB-2500-1, 100% Volume Coverage of Examination Volume A-B-C-D. 2.4. Impracticality of Compliance Component configuration:
- Surface 1 : Lower Shell Course -Carbon steel
- Surface 2: Lower Ring Section -Carbon steel
- Diameter:
170.000 in.
- Thickness:
5.500 in. This component was scanned with automated methods from the Reactor Vessel interior.
Scanning requirements are described in 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.
These requirements describe and are specific to scanning components in two axial and two circumferential directions.
This component was scanned to the extent possible to meet these requirements.
The aggregate coverage that was obtained is described and calculated from the following:
- Inner 15% thickness (T) coverage using 45°& 70° longitudinal waves for axial scans (S1, S2), and circumferential scans (CW, CCW) obtained 36.00% coverage.
- Outer 85% thickness (T) coverage using 45° longitudinal waves and 45° shear waves for axial scans (S1, S2), and circumferential scans (CW, CCW) obtained 44.00% coverage.
- The aggregate coverage was calculated to be (15%)(36%)
+ (85%)(44%)
= 43.00%. The impracticality was caused by the Reactor Vessel Interior configuration (Core Guide Lugs and Flow stabilizers) that does not allow meaningful interrogation.
The current configuration does not allow scanning of all of the required volume for this weld. The weld configuration would have to be redesigned and replaced, which is impractical.
Page 2 of31 Oconee Relief Request 15-0N-002 The Oconee lnservice 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. This relief request is specific to examination volume coverage limitations only. All other Code requirements were satisfied.
Indications were recorded and found to be acceptable during this examination.
2.5. Proposed Alternative and Basis for Use No substitution alternative for this weld is available which would provide better coverage.
Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws. Use of other manual or automated UT techniques, whether conventional or phased array, were considered, but would not increase coverage due to the limitation created by the component configuration.
The use of any other UT technique available would incur the same physical scanning limitations.
2.6. Duration of Proposed Alternative This request is for the fourth inservice inspection interval.
The interval ended on July 15, 2014. 2.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number 01.B1 .11.0005 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 provides additional assurance of pressure boundary integrity.
In addition to the above Code required examinations (volumetric and pressure test), 'Reactor Building Normal Sump monitoring and Reactor Building process radiation monitoring contribute to ensuring pressure boundary integrity by providing means to detect reactor coolant leakage and take prompt corrective actions. Duke Energy has examined the weld 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 XI, and the leakage monitoring, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety. 2.8. References Duke Energy Relief Request 02-0N-005 was approved by the NRC during the last inspection interval.
The previous approved SE is documented in Accession Number ML032721404, TAC No.MB5830 dated September 29, 2003. Page 3 of31 Oconee Relief Request 15-0N-002 3.0 Weld # 1-RPV-WR35 3.1. ASME Code Component(s)
Affected Unit 1 Reactor Vessel Lower Head Cap Section to Lower Head Ring Section Weld, Reactor Coolant System, Weld# 1-RPV-WR35, Summary Number 01.81 .21.0001, and ASME Code Class 1. 3.2. Applicable Code Edition and Addenda ASME Boiler and Pressure Vessel Code,Section XI, 1998 Edition through the 2000 Addenda. 3.3. Applicable Code Requirement IWB-2500, Table IWB-2500-1, Examination Category B-A, Item Number 81 .21 Fig. IWB-2500-3, 100% Volume Coverage of Examination Volume A-B-C-D. 3.4. Impracticality of Compliance Component configuration:
- Surface 1: Lower Head Cap Section -Carbon steel
- Surface 2: Lower Head Ring Section -Carbon steel
- Diameter:
143.00 in.
- Thickness:
5.375 in. This component was scanned with automated methods from the Reactor Vessel interior.
Scanning requirements are described in 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.

The aggregate coverage that was obtained is described and calculated from the following:
- Inner 15% thickness (T) coverage using 45°& 70° longitudinal waves for axial scans (S1, S2), and circumferential scans (CW, CCW) obtained 33.00% coverage.
- Outer 85% thickness (T) coverage using 45° longitudinal waves and 45° shear waves for axial scans (S1, S2), and circumferential scans (CW, CCW) obtained 37.00% coverage.
- The aggregate coverage was calculated to be (15%)(33%)
+ (85%)(37%)
= 36.00%. The impracticality was caused by the Reactor Vessel interior configuration (lncore Nozzles and Flow Stabilizers) that does not allow meaningful interrogation.
The current configuration does not allow scanning of all of the required volume for this weld. The weld configuration would have to be redesigned and replaced, which is impractical.

Affected Unit 1 Letdown Cooler, Head to Head, Reactor Coolant System, Weld # 1 INLET (same as weld ID: WJ-32), Summary Number 01.B2.51.0003, and ASME Code Class 1. 4.2. Applicable Code Edition and Addenda ASME Boiler and Pressure Vessel Code,Section XI, 1998 Edition through the 2000 Addenda. 4.3. Applicable Code Requirement IWB-2500, Table IWB-2500-1, Examination Category B-B, Item Number B2.51, Fig. IWB-2500-3, 100% Volume Coverage of Examination Volume A-B-C-D. 4.4. Impracticality of Compliance Component configuration:
- Surface 1: Chemical Connector
-Stainless steel
- Surface 2: Channel Body -Stainless steel
- Diameter:
- 8. 75 in.
- Thickness:
0.875 in. This component was scanned manually with conventional methods. Scanning requirements are described in 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.
These requirements describe and are specific to scanning components in two axial and two circumferential directions.
This component was scanned to the extent possible to meet these requirements.
The aggregate coverage that was obtained is described and calculated from the following:
- Axial scan coverage (S1 ,S2) using 4.5° Shear and Longitudinal and 60° & 70° Longitudinal waves obtained 97.2% coverage.
- Circumferential scan coverage (CW, CCW) using a 45° shear wave obtained 78.1 % coverage.
- The aggregate coverage was calculated to be (97.2% + 78:1%)/2 = 87.7%. The impracticality was caused by the taper configuration and nozzle on the chemical connector that does not allow meaningful interrogation.
In order to scan all of the required volume for this weld. The shell to sampling nozzle weld would have to be redesigned and replaced, which is impractical.
Page 6 of31 Oconee Relief Request 15-0N-002 The Oconee lnservice 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. This relief request is specific to examination volume coverage limitations only. All other Code requirements were satisfied.
No relevant indications were recorded during this examination.
The reject box on data sheet is marked for internal tracking purposes of the coverage limitation only. 4.5. Proposed Alternative and Basis for Use No substitution alternative for this weld is available which would provide better coverage.
Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws. Use of other manual or automated UT techniques, whether conventional or phased array, were considered, but would not increase coverage due to the limitation created by the component configuration.

- Surface 1: Chemical Connector
--Stainless Steel
- Surface 2: Channel Body -Stainless Steel
- Diameter:
- 8. 75 in.
- Thickness:
0.875 in. This component was scanned manually with conventional methods. Scanning requirements are described in 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.
These requirements describe and are specific to scanning components in two axial and two circumferential directions.
This component was scanned to the extent possible to meet these requirements.
The aggregate coverage that was obtained is described and calculated from the following:
- Axial scan coverage (S1 ,S2) using 45° Shear and Longitudinal and 60° & 70° Longitudinal waves obtained 97.2% coverage.
- Circumferential scan coverage (CW, CCW) using a 45° shear wave obtained 78.1 % coverage.
- The aggregate coverage was calculated to be (97.2% + 78.1%)/2 = 87.7%. The impracticality was caused by the taper configuration and nozzle on the chemical connector that does not allow meaningful interrogation.
In order to scan all of the required volume for this weld. The shell to sampling nozzle weld would have to be redesigned and replaced, which is impractical.
The Oconee lnservice 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. This relief request is specific to examination volume coverage limitations only. All other Code requirements were satisfied.
Page 8 of31 Oconee Relief Request 15-0N-002 No relevant indications were recorded during this examination.
The reject box on data sheet is marked for internal tracking purposes of the coverage limitation only. 5.5. Proposed Alternative and Basis for Use No substitution alternative for this weld is available which would provide better coverage.
Radiography
{RT) is not a desired option because RT is limited in the ability to detect service induced flaws. Use of other manual or automated techniques, whether conventional or phased array, were considered, but would not increase coverage due to the limitation created by the component configuration.
The use of any other technique available would incur the same physical scanning limitations.
5.6. Duration of Proposed Alternative This request is for the fourth inservice inspection interval.
The interval ended on July 15, 2014. 5.7. Justification for Granting Relief Ultrasonic examination of the weld for the item number 01.B2.51.0004 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 provides additional assurance of pressure boundary integrity.
In addition to the above Code required examinations (volumetric and pressure test), Reactor Building Normal Sump monitoring and Reactor Building process radiation monitoring contribute to ensuring pressure boundary integrity by providing means to detect reactor coolant leakage and take prompt corrective actions. Duke Energy has examined the weld 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 XI, and the leakage monitoring, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety. 5.8.

This component was scanned to the extent possible to meet these requirements.
The aggregate coverage that was obtained is described and calculated from the following:
- Examination coverage using a 45° shear wave and a 60° longitudinal wave for axial scans (S1) and 60° & 70° longitudinal waves for axial scans (S2).
- Examination coverage using 45° shear waves for circumfere'ntial (CW, CCW) scans (S1) and 60° & 70° longitudinal waves for circumferential (CW, CCW) scans (S2).
- Surface (S2) was scanned 100% but, no credit for Surface 2 volume is being taken since this side is fabricated from cast stainless material.
- The aggregate coverage was calculated to be (100.0% + 0% + 50.0%+ 50.0%)/4 = 50%. The impracticality was caused by the cast stainless material that does not allow meaningful interrogation from the Surface 2 RCP-1A1side.
The current configuration allows 100% scanning of all of the required volume for this weld, but credit for the surface 2 cast stainless side which is considered "best effort" is not being claimed. The weld configuration would have to be redesigned and replaced, which is impractical.

- Base material coverage using 45°, 60° & 70° shear wave for axial scans (S1) and 45° & 60° shear waves for circ. scans (CW, CCW) obtained 49.3% coverage.
- 0° scan coverage obtained 29.1 % coverage.
- The aggregate coverage was calculated to be (12.3% + 49.3% + 29.1%)/3 = 30.2%. The impracticality was caused by the weld taper configuration of the sampling nozzle to the shell that does not allow meaningful interrogation from Surface 2 nozzle side. In order to scan all of the required volume for this weld. The shell to sampling nozzle weld would have to be redesigned and replaced, which is impractical.
Page 22 of31 Oconee Relief Request 15-0N-002 The Oconee lnservice 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. This relief request is specific to examination volume coverage limitations only. All other Code requirements were satisfied.
No indications were recorded during this examination.
12.5. Proposed Alternative and Basis for Use No substitution alternative for this weld is available which would provide better coverage.
Radiography (RT) is not a desired option because RT is limited in the ability to detect service induced flaws. Use of other manual or automated UT techniques, whether conventional or phased array, were considered, but would not increase coverage due to the limitation created by the component configuration.
The use of any other UT technique available would incur the same physical scanning limitations.
12.6. Duration of Proposed Alternative This request is for the fourth inservice inspection interval.
The interval ended on July 15, 2014. 12. 7. Justification for Granting Relief Ultrasonic examination of the weld for the item number 02.B3.110.0010 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 provides additional assurance of pressure boundary integrity.
In addition to the above Code required examinations (volumetric and pressure test), Reactor Building Normal Sump monitoring and Reactor Building process radiation monitoring contribute to ensuring pressure boundary integrity by providing means to detect reactor coolant leakage and take prompt corrective actions. Duke Energy has examined the weld 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 XI, and the leakage monitoring, it is Duke's position that the combination of examinations provides a reasonable assurance of quality and safety. 12.8.
