Serial No. 17-110 Docket No. 50-338 NAPS Unit 1 4th Interval 2nd Period Limited Exams Page 6 of 45 A1. Pressurizer Nozzle-To-Vessel Welds 4.A1 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 8-D, Item No. 83.110. This requirement is considered impractical due to the pressurizer to nozzle weld configuration. As shown in the attached enclosures, ultrasonic examination of the following pressurizer nozzle-to-vessel welds are limited in coverage due to the pressurizer to nozzle weld configuration: Mark/Weld # Line # Scan Coverage % Enclosure 11 1-RC-E-2 78.36% A1-1 12 1-RC-E-2 78.36% A1-2 Examination of the subject pressurizer nozzle-to-vessel welds was performed to the extent possible using qualified equipment and no further coverage is possible with existing technology. Welds 11 and 12, safety valve nozzles, are limited to 78.36% due to nozzle geometry and because the cladding prevents extended V-path. Refer to Enclosures A1-1 and A1-2 for coverage details of the limitations experienced. Third interval relief for welds 11 and 12 was granted in Request N1-13-PRT-004-A4 (Reference 2) at 78.36% coverage. Second interval relief for welds 11 and 12 exam limitations was granted in Request NDE-20 at 72% coverage (different NOE guidelines for coverage calculations). 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 being 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 on either side of the subject welds. Although Dominion considers it 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
Serial No. 17-110 Docket No. 50-338 NAPS Unit 1 4th Interval 2nd Period Limited Exams Page 7 of 45 significant service-induced degradation. The examinations performed also provide reasonable assurance of the 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 examinations performed should detect any general patterns of degradation that may occur in the areas covered, providing reasonable assurance of the continued structural integrity of the subject welds. 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 would be manifested should they occur. Manual scanning was used 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 A1-1 and A1-2 include the complete Ultrasonic Examination Data Reports for each Category 8-0, Item 83.110, examination included in this relief 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 A1-1 and A1-2 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).

- cw !Circumferential scan in the clock-wise direction *
****************** TCcw !Circumferential scan in the counterciock:wisedirection The above examinations were performed manually using advanced ASME Section XI, Appendix VIII demonstrated procedures and techniques in accordance with the performance demonstration requirements. Based on the 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.
Enclosures R1-1 through R1-4 include the complete Ultrasonic Examination Data Records for each Category R-A, Item R1 .11, examination included in this relief request. Each report includes details of the UT scanning apparatus, including transducer size, fr:_equency, 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. The only indication identified during these examinations was counter bore geometry seen 360° intermittently and verified by higher angles and the plot for weld 14. No other recordable indications were identified during any of these examinations. Weld 2 (6"-RC-18), Reactor Coolant System Class 1, was a single-sided examination (50% coverage) due to the valve-to-pipe configuration, limiting upstream scans. The weld is at the check valve from the Low Head Safety Injection system into the Reactor Coolant system hot leg (29"-RC-4). An additional "Best Effort" (non-Code) scan with a 60 degree Longitudinal search unit obtained an additional 1. 7% total coverage of the upstream side of the weld. Line# 6"-RC-18 is 1,500 lb., Type 316 seamless stainless steel piping. Weld 2 is constructed with welding filler metal SFA 5.4 E316L-16, SFA 5.9
Serial No. 17-110 Docket No. 50-338 NAPS Unit 1 41h Interval 2nd Period Limited Exams Page 21of45 ER316L, and/or SFA 5.30 IN316L procured with 8-20 FN delta ferrite and 75ksi minimum tensile strength. Weld 2 is also managed as part of the augmented thermal fatigue examination requirements of MRP-146 like other welds with similar configurations. Weld 13 (6"-RC-19), Reactor Coolant System Class 1, was a single-sided examination (50% coverage) due to the valve-to-pipe configuration, limiting upstream scans. The weld is at the check valve from the Low Head Safety Injection system into the Reactor Coolant system cold leg (27 1/2"-RC-6). An additional "Best Effort" (non-Code) scan with a 60 degree Longitudinal search unit obtained 13% additional total coverage of the upstream side of the weld. Line# 6"-RC-19 is 1,500 lb., Type 316 seamless stainless steel piping. Weld 13 is constructed with welding filler metal SFA 5.4 E316L-16, SFA 5.9 ER316L, and or SFA 5.30 IN316L procured with 8-20 FN delta ferrite and 75ksi minimum tensile strength. Weld 13 is also managed as part of the augmented thermal fatigue examination requirements of MRP-146 like other welds with similar configurations. Weld 14 (6"-RC-19), Reactor Coolant System Class 1, was a single-sided examination (50% coverage) due to the elbow-to-branch configuration, limiting downstream scans. The weld is at the weldolet from the Low Head Safety Injection system into the Reactor Coolant system cold leg (27 1/2"-RC-6). An additional "Best Effort" (non-Code) scan with a 60 degree Longitudinal search unit obtained 9% additional total coverage of the downstream side of the weld. Line# 6"-RC-19 is 1,500 lb., Type 316 seamless stainless steel piping. Weld 14 is constructed with welding filler metal SFA5.4 E316L-16, SFA 5.9 ER316L, and or SFA 5.30 IN316L procured with 8-20 FN delta ferrite and 75ksi minimum tensile strength. Weld 14 is also managed as part of the augmented thermal fatigue examination requirements of MRP-146 like other welds with similar configurations. Weld SW-1 (3"-CH-1), Charging System Class 1, was a limited examination (88% coverage) due a welded ID tag and the intrados of the elbow (elbow-to-pipe configuration), limiting upstream and downstream scans. The weld is at the elbow of the Charging line from the Regenerative Heat Exchanger into the Reactor Coolant system cold leg (27 1/2"-RC-6). An additional "Best Effort" (non-Code) scan with a 60 degree Longitudinal search unit obtained 12% additional total coverage of the upstream and downstream sides of the weld. Line# 3"-CH-1 is 1,500 lb., Type 316 seamless stainless steel piping. Weld SW-1 is constructed with welding filler metal SFA 5.4 E316L-16, SFA 5.9 ER316L, and or SFA 5.30 IN316L procured with 8-20 FN delta ferrite and 75ksi minimum tensile strength. The North Anna Unit 1 RI-ISi Program is based on ASME Code Case N-716 as identified in approved request N1-14-Rl-001 (Reference 7). The subject 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. The subject 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 after operating pressure and temperature is achieved before unit startup. Weld examinations for welds 2, 13, and 14 were single-sided, but additional non-Code coverage was obtained (Best Effort Coverage) on ttie critical inside surface volume of both the weld and heat-affected area. These additional measures provide reasonable assurance that these welds are structurally sound. The subject welds were selected as part of an examination program that includes selections from different piping
Serial No. 17-110 Docket No. 50-338 NAPS Unit 1 4th Interval 2nd Period Limited Exams Page 22 of 45 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, valve-to-pipe, elbow-to-branch, and a welded tag at an elbow, confines inspection capabilities. Detailed sketches of the limitations and inspection areas achieved have been provided. No further action can be taken to enable better examination coverage without destroying the component. 6.R1 PROPOSED ALTERNATIVE AND BASIS These welds were selected as they are determined to be of High Safety Significance 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 a previous Section 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 performed at the end of each refueling outage. As a result of the completed examinations, any pattern of degradation should be detected, thereby providing reasonable assurance of operational readiness. The purpose of the inservice inspection 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. In cases other than most piping-to-piping welds the majority of weld examinations are considered single-sided examinations. The risk-informed weld limitations are considered in ASME Code Case N-716 periodic updates to the Risk-Informed Program Plan, where the program is reevaluated to determine if any changes to the examination selections need to be made, including additional examinations if they are warranted. The limited examinations identified in this request have no impact on the change-in-risk evaluation for the second period, and no new examinations were added as a result of these limitations.
