Pressurizer Nozzle-To-Vessel Welds 4.AI IMPRACTICALITY OF COMPLIANCE In accordance with 10CFR50.55a(g)(5)(iii), relief is requested from the "essentially 100 percent" volumetric examination coverage requirement for the identified Pressurizer Nozzle-To-Vessel Welds, ASME Section XI Category B-D, Item No. B3.110. This requirement is considered impractical due to the pressurizer to nozzle weld configuration.

Ultrasonic examination of the following pressurizer nozzle-to-vessel welds are limited in coverage due to the pressurizer to nozzle weld configuration as shown in the attached enclosures. Examination was performed to the extent possible using qualified equipment, and no further coverage is possible with existing technology.

Mark/Weld # Line # Scan Coverage % Enclosure 10 2-RC-E-2 56.6% Al-1 14 2-RC-E-2 56.7% A1-2 Weld 10, a safety valve nozzle, is limited to 56.6% due to nozzle geometry and because the cladding prevents extended V-path. Refer to Enclosure Al-1 for coverage details of the limitations experienced. Third interval relief for weld 10 was granted per Request N2-13-PRT-002-A5 at 56.6% coverage. Second interval relief for weld 10 exam limitations was granted in Request NDE-19 at 72% coverage (different NDE guidelines for coverage calculations).

Weld 14, the spray nozzle, is limited to 56.7% due to the weld location in relation to the nozzle. Refer to Enclosure A1-2 for coverage details of the limitations experienced.

Third interval relief for weld 14 was granted per Request N2-13-PRT-002-A5 at 56.7%

coverage. Second interval relief for weld 14 exam limitations was granted in Request NDE-20 at 56.6% coverage.

The subject pressurizer nozzle-to-vessel welds are constructed of SA-508 Class 2, a P-Number 3, Group Number 3 carbon steel material, with austenitic stainless steel inside diameter cladding and stainless steel inserts. The welds extend the full thickness of the pressurizer vessel. Pressurizer upper and lower heads are fabricated from SA-533 Grade A, Class 2 carbon steel. The existing nozzle to pressurizer upper and lower heads are welded with low alloy steel filler, essentially the same as the nozzle material.

The subject pressurizer nozzles have a minimum thickness of 2.5 inches with 0.19 inch cladding. These nozzles are of the "set-in" design which essentially makes the welds concentric rings aligned parallel with the nozzle axes in the through-wall direction of the pressurizer vessel. This design geometry limits ASME Code-required UT angle beam examinations to be performed primarily from the vessel side of the welds.

Although UT scans were primarily limited to the vessel side only, studies have found that inspections conducted through carbon steel are equally effective whether the ultrasonic waves have only to propagate through the base metal, or have to also propagate through the carbon steel weldment. Therefore, due to the fine-grained carbon steel microstructures, it is expected that the UT techniques employed would have detected structurally significant flaws that may have occurred on either side of the subject welds.

Serial No.14-050 Docket No. 50-339 NAPS Unit 2 - 4 th Interval 1 st Period Limited Exams Page 8 of 86 Although Dominion considers it is impractical to meet the ASME Code-required 100%

volumetric examination coverage for the subject pressurizer nozzle-to-vessel welds due to nozzle configuration, it is believed that the coverage obtained would have identified significant service-induced degradation. The examinations performed also provide a reasonable assurance of structural integrity of the subject welds.

5.A1 BURDEN CAUSED BY COMPLIANCE The ASME Code requires that the volumetric examination be conducted from both sides of these pressure retaining welds, however, the design configurations limit access for UT scanning primarily to the vessel side of the welds. In order to effectively increase the examination coverage, the nozzle-to-vessel welds would require design modifications or replacement. This is considered a burden making the ASME Code volumetric examination requirements impractical, which is contrary to the intent of the Code.

6.A1 PROPOSED ALTERNATIVE AND BASIS It is proposed that the examinations already completed at the reduced coverage be accepted as meeting the Code requirements. Alternative components could not be substituted for examination due to the mandatory selection requirements of the Code. The limited volumetric examination performed should detect any general patterns of degradation that may occur in the areas covered, therefore providing reasonable assurance of the continued structural integrity of the subject weld.

UT examinations were conducted using ASME Code,Section V, Article 4, techniques and included 0-degree longitudinal, and 45- and 60- degree shear waves from the vessel side.

The examination volumes included the weld and base materials near the inside surface of the weld joint, which are typically the highest regions of stress, and where the expected degradation sources to be manifested should they occur. Manual scanning was performed for these examinations. The configuration of the nozzle to shell weld limits the effective examination of the required examination volume. The nozzle's close proximity to the weld limits scanning due to the nozzle bend radius causing lift-off of the search unit during scanning. No recordable indications were identified during these examinations. The physical configuration of each nozzle limits the effectiveness of alternative or advanced technologies from increasing the examination coverage for this configuration.

Enclosures Al-1 and A1-2 include the complete Ultrasonic Examination Data Records for each Category B-D, Item B3.110, examination included in this request. Each report includes details of the UT scanning parameters, including transducer size, frequency and angle. Also included are coverage plots for each of the examinations showing the nozzle configuration and percent coverage for each individual scan.

The Al Enclosures include search unit details, wave modality, and insonification angles used for all examinations, including the results of each scan. The examinations were performed with 45 degree shear wave, 60 degree shear wave, and 0 degree longitudinal wave search units (as identified in the reports).

Serial No.14-050 Docket No. 50-339 NAPS Unit 2 4th Interval 1s' Period Limited Exams Page 27 of 86 B1. Head Circumferential Welds 4.B1 IMPRACTICALITY OF COMPLIANCE In accordance with 10CFR50.55a(g)(5)(iii), relief is requested from the "essentially 100 percent" volumetric examination coverage requirement for the identified vessel to head circumferential weld. This requirement is considered impractical due to weld configuration, including supports, thermocouples, and weld profile.

Ultrasonic examination of the full 165 inches of weld length of the lower head circumferential weld on the boron injection tank is limited to 87.6 percent due to four supports obstructing eight inches of weld length each, two installed thermocouples obstructing 1.8 inches each, and 0.9 inches obstructed by the weld profile. Refer to Enclosure B1-1 for coverage details for the vessel to head circumferential weld (weld #

1). Examination was performed to the extent possible.

5.B1 BURDEN CAUSED BY COMPLIANCE Destruction of the component, including removal of welded supports and thermocouples, would be necessary to perform 100% of the Code required examination as written in the 2004 ASME Section Xl Code with No Addenda and is contrary to the intent of the Code.

6.B1 PROPOSED ALTERNATIVE AND BASIS It is proposed that the examinations already completed in the fourth interval at reduced coverage be accepted as meeting the Code requirements. The limited volumetric examination performed should detect any general patterns of degradation that may occur in the areas covered, therefore providing reasonable assurance of the continued structural integrity of the subject weld.

One other component in category C-A, Item No. C1.20, on the boron injection tank, is scheduled for examination during the current interval.

The examinations were performed using standard ASME Section V, Article 4 UT techniques. Manual scanning was performed for these examinations.

Enclosure B1-1 includes the complete Ultrasonic Examination Data Record for the Category C-A, Item C1.20, examination included in this request. The report includes details of the UT scanning apparatus, including transducer size, frequency and angle.

Also included are scan plots for the examination showing limitation locations. The wave modality and insonification angles are also included. No recordable indications were identified during the examination.

The Boron Injection Tank head is ASTM A-516 Grade 70 carbon steel with 0.125" weld deposit clad ASTM A-240 Type 304L. Tank head design thickness is a minimum of 2.00".

Serial No.14-050 Docket No. 50-339 NAPS Unit 2 4u' Interval 1 st Period Limited Exams Page 39 of 86 B2. Nozzle-to-Shell Welds 4.B2 IMPRACTICALITY OF COMPLIANCE In accordance with 10CFR50.55a(g)(5)(iii), relief is requested from the "essentially 100 percent" volumetric examination coverage requirement for the identified Nozzle-to-Vessel welds. This requirement is considered impractical due to single-sided access.

Ultrasonic examination of the identified nozzle-to-vessel weld on the boron injection tank is limited to 27.4% volume coverage because of single-sided access due to nozzle to shell weld configuration. It was not possible to scan over the weld with any angle.

Refer to Enclosure B2-1 for coverage details for weld # 3. Examination was performed to the extent possible.

5.B2 BURDEN CAUSED BY COMPLIANCE Destruction of the component, requiring a completely different design, would be necessary to perform 100% of the Code required examination as written in the 2004 ASME Section XI Code with No Addenda and is contrary to the intent of the Code.

6.B2 PROPOSED ALTERNATIVE AND BASIS It is proposed that the examinations already completed at the reduced coverage be accepted as meeting the Code requirements. The limited volumetric examination performed should detect any general patterns of degradation that may occur in the areas covered, therefore providing reasonable assurance of the continued structural integrity of the subject weld. 100 percent magnetic particle examination coverage was obtained with no reported recordable indications.

Two other components are scheduled to be examined in Category C-B, Item No. C2.21, in the fourth ISI inspection interval on similar nozzle welds. Previous examinations at these locations obtained full coverage. Third interval relief for the examination of weld #3 was granted in request N2-13-PRT-002, Section B1, for essentially the same examination coverage of 30.5%.

The examinations were performed using standard ASME Section V, Article 4 UT techniques. Manual scanning was performed for these examinations. The configuration of the nozzle to shell weld limits the effective examination of the required examination volume. The nozzle's close proximity to the weld limits scanning due to the nozzle blend radius causing lift-off of the search unit during scanning. The physical limitation of each nozzle limits the effectiveness of alternative or advanced technologies from increasing the examination coverage for this configuration.

Enclosure B2-1 includes the complete Ultrasonic Examination Data Record for the Category C-B, Item C2.21, examination included in this request. The report includes details of the UT scanning apparatus, including transducer size, frequency and angle.

Also included are scan plots for the examination showing the nozzle configuration and percent coverage for each individual scan. The wave modality and insonification angles are also included. No recordable indications were identified during the examination.

. Serial No.14-050 Docket No. 50-339 NAPS Unit 2 4th Interval 1 st Period Limited Exams Page 40 of 86 Magnetic Particle Examination (MT) was performed for the subject weld included in this request, and the exam was a full ASME Code examination (>90% coverage). There were no recordable indications detected. The complete MT Examination report is included in Enclosure B2-1.

The Boron Injection Tank head is ASTM A-516 Grade 70 carbon steel with 0.125" weld deposit clad ASTM A-240 Type 304L. Tank head design thickness is a minimum of 2.00". The nozzles are ASTM A-508 Class 1, and are just over 5" thick. The nozzles are also clad with ASTM A-240 Type 304L.

Risk-Informed Piping Welds Subject to Thermal Fatigue 4.R1 IMPRACTICALITY OF COMPLIANCE In accordance with 10CFR50.55a(g)(5)(iii), relief is requested from the "essentially 100 percent" volumetric examination coverage requirement for the identified piping welds.

This requirement is considered impractical primarily due to single-sided access and configuration for these components.

These examinations were performed manually using advanced ASME Section XI, Appendix VIII demonstrated procedures and techniques in accordance with the performance demonstration requirements. Based on access and physical limitations of these welds, alternative or other advanced technologies would not have provided complete coverage of the examination volume at the time of these examinations.

The attached enclosures include the complete Ultrasonic Examination Data Records for each Category R-A, Item R1.11, examination included in this request. Each report includes details of the UT scanning apparatus, including transducer size, frequency, angle, wave modality and insonification angles. Also included are scan plots for each of the examinations showing the piping configuration and percent coverage for each individual scan. No recordable indications were identified for any of these examinations.

Weld 2B (6"-RC-420), Reactor Coolant System Class 1, was a single-sided examination due to the nozzle to pipe configuration, limiting upstream scans. The weld is at the nozzle from Low Head Safety Injection into the Reactor Coolant cold leg (27 1/2"-RC-409).

Additional "Best Effort" (non-Code) scan with a 60 degree Longitudinal search unit obtained additional 4% total coverage of the downstream side of the weld. Additionally, liquid penetrant examination (LP) was performed with no identified indications. Weld 2B in Line# 6"-RC-420, is 1,500 lb., Type 316 seamless stainless steel piping, with welding filler metal SFA 5.4 E316L-16, SFA 5.9 ER316L, and or SFA 5.30 1N316L procured with 8-20 FN delta ferrite and 75ksi minimum tensile strength.

Weld 7 (3"-RC-615), Reactor Coolant System Class 1, was a single-sided examination due to the pipe to valve configuration, limiting upstream scans. The weld is on the Reactor Coolant drain line off the crossover leg at valve 2-RC-HCV-2557A. Additional "Best Effort" (non-Code) scan with a 70 degree shear search unit obtained additional 9%

Serial No.14-050 Docket No. 50-339 NAPS Unit 2 4th interval 1 st Period Limited Exams Page 48 of 86 total coverage of the downstream side of the weld. Weld 7 in Line# 3"-RC-615, is 1,500 lb., Type 316 seamless stainless steel piping, with welding filler metal SFA 5.4 E316L-16, SFA 5.9 ER316L, and or SFA 5.30 1N316L procured with 8-20 FN delta ferrite and 75ksi minimum tensile strength.

The NAPS 2 Risk-Informed ISI Program is based on ASME Code Case N-716 as identified in approved request N2-14-RI-001. These limitations have been evaluated as acceptable, with no impact on risk analysis, and no further actions necessary to provide reasonable assurance of pressure boundary leak tightness. Both of these welds are included in the Class 1 pressure boundary, receiving visual examinations at the beginning of each refueling outage as part of the Boric Acid Corrosion Control Program and VT-2 visual examinations at the end of the refueling outage once operating pressure and temperature is achieved before unit startup.

Both of these weld examinations were single-sided, but additional non-Code coverage was obtained (Best Effort Coverage) on the critical inside surface volume of both the weld and heat-affected area. These are additional measures that provide reasonable assurance that these welds are structurally sound. An effective examination program must include selections from different piping configurations, as well as selections from piping configurations categorized with different degradation mechanisms.

5.R1 BURDEN CAUSED BY COMPLIANCE The physical configuration of these welds, nozzle to pipe and pipe to valve, confines inspection capabilities. Detailed sketches of the limitations and inspection areas achieved have been provided. No further actions can enable better examination coverage without destroying the component.

6.R1 PROPOSED ALTERNATIVE AND BASIS These welds were selected as they are determined High Safety Significant with possible active degradation mechanisms. Selections were made based on plant specific operating experience or history of examination, weld repairs, random selection across different pipe sizes and configurations, and radiation concerns. These welds were selected, in part, because previousSection XI examination history exists. Comparison of examination results over time is critical to detect service induced degradation. Inspection of these particular welds are considered the best choice for meaningful examination results.

It is proposed that the examinations already completed at the reduced coverage be accepted for meeting the Code requirements. 100% of the pipe to valve welds were volumetrically examined from one side. No indications were discovered. The limited volumetric examinations performed should detect any general patterns of degradation that may occur in the areas covered, therefore providing reasonable assurance of the continued structural integrity of the subject weld. In addition, these welds receive a visual examination during the system leakage test. Therefore, any pattern of degradation should be detected by these examinations ensuring reasonable assurance of operational readiness.

The purpose of the inservice inspection (ISI) program is to assure the structural and pressure-retaining integrity of safety-related nuclear power plant components in

Serial No.14-050 Docket No. 50-339 NAPS Unit 2 4th Interval 1st Period Limited Exams Page 49 of 86 accordance with the rules of the ASME Section XI Code and the requirements of 10 CFR 50.55a. Although Dominion could select only weld locations where greater than 90%

examination coverage is possible (when available based on selection criteria), meeting the purpose of the Code requires selecting a mix of not only piping-to-piping welds (where essentially 100% coverage is more likely), but also piping-to-valve welds, piping-to-pump welds, piping-to-vessel welds, socket welds, nozzle-to-pipe welds, etc. The ASME Code allows only 50% Code coverage for single-sided examinations, and in cases other than most piping-to-piping welds, the majority of weld examinations are considered single-sided examinations.

Lccw circumnferential scan in the counter clock-wise direction These examinations were performed manually using advanced ASME Section XI, Appendix VIII demonstrated procedures and techniques in accordance with the performance demonstration requirements. Based on access and physical limitations of these welds, alternative or other advanced technologies would not have provided complete coverage of the examination volume at the time of these examinations.

The attached enclosures include the complete Ultrasonic Examination Data Records for each Category R-A, Item R1.20, examination included in this request. Each report includes details of the UT scanning apparatus, including transducer size, frequency, angle, wave modality and insonification angles. Also included are scan plots for each of the examinations showing the piping configuration and percent coverage for each individual scan.

Weld SW-5 (32"-SHP-459), Main Steam System Non-Classed, is a Main Steam pipe to header weld. The configuration is a mitered shop weld from 32-inch piping to the horizontal 40-inch Main Steam header. The 32-inch piping is carbon steel, A155EFW, CLI, CMS 75, and the 40-inch header is carbon steel, A155EFW, CLI, KC 70. Full coverage was obtained at the tops and bottoms of the welds, but limitations existed at the sides where the angle between the pipe and the header is at right angles. This weld is a non-class weld included as a high safety significant, break exclusion region, RISB location requiring >90% coverage per request N2-14-RI-001, and as such is included in this request. The UT examination identified two recordable indications: 1) The first indication evaluated as acceptable per ASME Section XI Table IWB-3514-1, and 2) The

Serial No.14-050 Docket No. 50-339 NAPS Unit 2 4t Interval 1 st Period Limited Exams Page 62 of 86 second identified as Inner Diameter Geometry. Beam plots, profiles, along with UT signals were used to characterize the geometrical condition of weld SW-5. The indications were evaluated using the Indication Classification guidance of the Appendix VIII qualified procedure utilized for the examination. Augmented magnetic particle examination was also performed at this location with no reportable indications identified.

Weld 4 (6"-RC-416), Reactor Coolant System Class 1,45 degree elbow to branch connection weldolet, is a seamless stainless steel elbow to stainless steel weldolet. This weld is 1,500 lb., A-403-WP316 Schedule 160 seamless stainless steel fitting, with welding filler metal SFA 5.4 E316L-16, SFA 5.9 ER316L, and or SFA 5.30 1N316L procured with 8-20 FN delta ferrite and 75ksi minimum tensile strength, and the weldolet is A-403-WP316 stainless steel. Coverage is limited because of the pipe to weldolet configuration, limiting the examination mostly to the upstream side. The cast nozzle configuration permits a weldolet side circumferential scan. Seventy-five percent Code coverage was obtained. An additional 15 percent Best Effort (non-Code) coverage was obtained with a 60 degree longitudinal search unit from the downstream (valve) side.

Weld 6A (3'-CH-814), Chemical and Volume Control System Class 1, is a 3-inch check valve to elbow weld in the pressurizer auxiliary spray piping. This weld connects A403-WP316 Sch 160 components, with welding filler metal SFA 5.4 E316L-16, SFA 5.9 ER316L, and or SFA 5.30 1N316L procured with 8-20 FN delta ferrite and 75ksi minimum tensile strength. Coverage is limited because of the single-sided weld to a valve and the configuration of the adjacent elbow, permitting only downstream examination. Allowable Code coverage is limited to no more than 50 percent.

The NAPS 2 Risk-Informed ISI Program is based on ASME Code Case N-716 as identified in approved request N2-14-RI-001. These limitations have been evaluated as acceptable, with no impact on risk analysis, and no further actions necessary to provide reasonable assurance of pressure boundary leak tightness. Welds 4 and 6A are included in the Class 1 pressure boundary, receiving visual examinations at the beginning of each refueling outage as part of the Boric Acid Corrosion Control Program and VT-2 visual examinations at the end of the refueling outage once operating pressure and temperature is achieved before unit startup. The Main Steam System weld received complete surface examination (magnetic particle) as it is included in the augmented inspection program for Main Steam System Postulated Break Locations and the associated line is regularly walked down during normal operator rounds.

These weld examinations were limited due to configuration, but additional non-Code coverage was obtained (Best Effort Coverage) on the critical inside surface volume of both the weld and heat-affected area. These additional measures provide reasonable assurance that these welds are structurally sound. An effective examination program must include selections from different piping configurations, as well as selections from piping configurations categorized with different degradation mechanisms.

Serial No.14-050 Docket No. 50-339 NAPS Unit 2 4th Interval 1s Period Limited Page 63Exams of 86 5.R2 BURDEN CAUSED BY COMPLIANCE The purpose of nondestructive examination (NDE) is to perform inspections without destroying the component. The physical configuration of these welds, pipe to header, elbow to weldolet, and valve to elbow, limits inspection capabilities.

Detailed sketches of the limitations and inspection areas achieved have been provided. No further actions can enable better examination coverage.

6.R2 PROPOSED ALTERNATIVE AND BASIS These welds were selected as part of the High Safety Significant population; however, no active degradation mechanism has been identified for them. Selections were made based on plant specific operating experience or history of examination, weld repairs, random selection across different pipe sizes and configurations, and radiation concerns. Welds were selected, in part, because previousSection XI examination history exists in some cases. Comparison of examination results over time is critical to detect service induced degradation. Inspection of these particular welds are considered the best choices for meaningful examination results.

It is proposed that the examinations already completed at the reduced coverage be accepted for meeting the Code requirements. 100% of the pipe to valve welds were volumetrically examined from one side. Although two recordable indications were identified, no unacceptable indications were discovered. The limited volumetric examinations performed should detect any general patterns of degradation that may occur in the areas covered, therefore providing reasonable assurance of the continued structural integrity of the subject weld. In addition, these welds receive a visual examination during the system leakage test. Therefore, any pattern of degradation should be detected by these examinations ensuring reasonable assurance of operational readiness.

The purpose of the inservice inspection (ISI) program is to assure the structural and pressure-retaining integrity of safety-related nuclear power plant components in accordance with the rules of the ASME Section XI Code and the requirements of 10 CFR 50.55a. Although Dominion could select only weld locations where greater than 90% examination coverage is possible (when available based on selection criteria), meeting the purpose of the Code requires selecting a mix of not only piping-to-piping welds (where essentially 100% coverage is more likely), but also piping-to-valve welds, piping-to-pump welds, piping-to-vessel welds, socket welds, nozzle-to-pipe welds, etc. The ASME Code allows only 50% Code coverage for single-sided examinations, and in cases other than most piping-to-piping welds, the majority of weld examinations are considered single-sided examinations.

.7.0 DURATION OF PROPOSED ALTERNATIVE The proposed alternatives in this request if approved will be applicable for the fourth 10 year ISI interval for NAPS 2 which ends December 13, 2020.

8.0 PRECEDENTS Similar relief was granted in the Third Inservice Inspection (ISI) Interval, as follows:

1. Request N2-13-PRT-002-A5 granted for limited coverage for ASME Section XI Exam category B-D, Item No. B3.110 items.

2. Request N2-13-PRT-002-B1 granted for limited coverage for ASME Section X1 Exam category C-B, Item No. C2.21 items.

3. Request N2-13-PRT-002-R1 granted for limited coverage for Risk-Informed examinations on weld 2B (6"-RC-420).

Although Fourth Interval Risk-Informed selections are different from those for the Third Interval, alternative requests were granted for examinations in similar locations with the same service conditions as identified in requests NI-13-PRT-004-R1 and N2-13-PRT-002-R1.

North Anna Power Station Unit 1 was granted similar alternative requests for Fourth Interval First Period Limitations in request N1-14-LMT-001.
