In addition to the periodic visual inspections performed under ASME Section XI and Generic Letter 88-05, reactor coolant pressure boundary leakage is monitored through a number of other activities, which provide a high level of confidence that in the unlikely event that leakage did occur, it would be detected and proper action taken. Specifically, system leak rate limitations imposed by Technical Specification 3.4.13, "RCS Operational Leakage," as well as the reactor makeup control system, reactor cavity and containment floor drain sump monitoring, containment radiation monitoring, and containment atmospheric monitoring, provide additional assurance that any leakage would be detected prior to gross failure of these components.

The surface geometry of the flange obstructs the ultrasonic transducer movement that is needed to examine the Code required volume from the flange side. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the head/cladding interface. In addition to the examination limitations encountered due to the flange configuration and inside diameter cladding, additional examination restrictions are caused by the presence of three lifting lugs located on the reactor vessel head. These limitations preclude complete coverage of the full volume for the required scanning directions mandated by ASME Section V and Section XI. These limitations are inherent to the original design of the reactor vessel head. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the reactor vessel head.

4.0 Impracticality/Burden The pressurizer vessel spray nozzle-to-vessel weld is approximately 2.7" thick. The pressurizer nozzle and vessel are clad with stainless steel on the inside diameter surface. The geometry of the nozzle along with the presence of the cladding on the inside diameter of the pressurizer result in limited access to the entire examination volume. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. The nozzle geometry tapers away from the weld resulting in limited scanning surfaces available for transducer coupling on the nozzle side of the weld resulting in additional examination limitations. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section XI. These limitations are inherent to the original design of the pressurizer vessel. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the pressurizer vessel.

5.0 Alternative Examinations or Testing In addition to performing the 0, 45, 60, and 70 degree scans to the extent practical as required by Appendix I, additional 30 and 40 degree scans were performed to supplement coverage. The aggregate examination coverage achieved was 69.84%.

In addition to completing the required volumetric examination to the extent practical, numerous system leakage tests (ASME Section Xl Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (5570 F) as well as the bare metal visual examinations associated with NRC Bulletin 2004-01 of the upper pressurizer vessel head were completed with no evidence of leakage associated with the pressurizer spray nozzle-to-vessel weld noted during the course of the interval.

4.0 Impracticality/Burden The pressurizer vessel relief nozzle-to-vessel weld is approximately 2.7" thick. The pressurizer nozzle and vessel are clad with stainless steel on the inside diameter surface. The geometry of the nozzle along with the presence of the cladding on the inside diameter of the pressurizer result in limited access to the entire examination volume. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. The nozzle geometry tapers away from the weld resulting in limited scanning surfaces available for transducer coupling on the nozzle side of the weld resulting in additional examination limitations. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section Xl. These limitations are inherent to the original design of the pressurizer vessel. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the pressurizer vessel.

Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. The nozzle geometry tapers away from the weld resulting in limited scanning surfaces available for transducer coupling on the nozzle side of the weld resulting in additional examination limitations. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section Xl. These limitations are inherent to the original design of the pressurizer vessel. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the pressurizer vessel.
5.0 Alternative Examinations or Testing In addition to performing the 0, 45, 60, and 70 degree scans to the extent practical as required by Appendix I, additional 30 and 40 degree scans were performed to supplement coverage. The aggregate examination coverage achieved was 73.6%.

In addition to completing the required volumetric examination to the extent practical, numerous system leakage tests (ASME Section Xl Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (5570 F) as well as the bare metal visual examinations associated with NRC Bulletin 2004-01 of the upper pressurizer vessel head were completed with no evidence of leakage associated with the pressurizer relief nozzle-to-vessel weld noted during the course of the interval.

Radiography as an alternative is not feasible because access is not available for film placement. No alternative examinations are planned for the weld during the current inspection interval.

4.0 Impracticality/Burden This austenitic stainless steel pipe-to-valve weld and associated base materials are 4" NPS with a nominal wall thickness of 0.531" (Schedule 160) and forms the break between the "RC" and "RY" subsystem for the pressurizer spray line. Under the Braidwood Risk-Informed ISI Program, the welds associated with this particular piping segment are considered Category R-A, Item R1.20 which are not subject to any specific degradation mechanisms. This weld had been examined during the first ISI inspection interval as a "structural discontinuity" and was reselected again in the second interval under the Risk-Informed ISI Program. These examinations were performed using examination procedures and personnel qualified under the Performance Demonstration Initiative (PDI) program administered through the EPRI NDE Center, specifically, PDI-UT-2 which is qualified for manual IGSCC detection and length sizing for austenitic stainless steel welds. The PDI procedure is not qualified for the detection of flaws on the far side of single sided access examinations on austenitic stainless steel piping welds. The valve geometry tapers away from the weld resulting in limited scanning

Figure 4-3 of Reference 8.1 depicts the required examination volume (A-B-C-D), which includes the lower 1/3 thickness of the circumferential weld. There was no counterbore detected, so the volume 1/2" each side of the weld toes (shown in Figure 4-2 of Reference 8.1) was use to define the required examination volume.

4.0 Impracticality/Burden The auxiliary feedwater safe end-to-nozzle weld and associated adjacent base materials are approximately 1.1" thick. This full penetration weld is Inconel 690 material but is not in contact with reactor coolant. This weld was shop fabricated and installed during the Unit 1 steam generator replacement during the Al R07 refuel outage (fall 1998). Under the Braidwood Risk-Informed ISI Program, the welds associated with this particular segment are considered Category R-A, Item R1.20, which are not subject to any specific degradation mechanisms. Due to the physical configuration of the carbon steel nozzle, which includes an adjacent taper running away from the circumferential weld, limitations preventing scanning (limitation calculated to be 35.5% for nozzle side circumferential scans) to attain coverage of 90% exist. In accordance with PDI-UT-10 requirements, 35, 40, 45, and 60 degree shear and 45 and 60 degree refracted longitudinal wave (RL) scans of this weld were performed to the extent practical. The aggregate examination coverage achieved was 79%.

The surface geometry of the flange obstructs the ultrasonic transducer movement that is needed to examine the Code required volume from the flange side. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. In addition to the examination limitations encountered due to the flange configuration and inside diameter cladding, additional examination restrictions are caused by the presence of three lifting lugs located on the reactor vessel head. These limitations preclude complete coverage of the full volume for the required scanning directions mandated by ASME Section V and Section XI. These limitations are inherent to the original design of the reactor vessel head. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the reactor vessel head.

4.0 Impracticality/Burden The pressurizer vessel spray nozzle-to-vessel weld is approximately 2.7" thick. The pressurizer nozzle and vessel are clad with stainless steel on the inside diameter surface. The geometry of the nozzle along with the presence of the cladding on the inside diameter of the pressurizer result in limited access to the entire examination volume. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. The nozzle geometry tapers away from the weld resulting in limited scanning surfaces available for transducer coupling on the nozzle side of the weld resulting in additional examination limitations. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section XI. These limitations are inherent to the original design of the pressurizer vessel. Conformance with the ASME Section XI requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the pressurizer vessel.

The aggregate examination coverage achieved was 83.64%.
In addition to completing the required volumetric examination to the extent practical, numerous system leakage tests (ASME Section XI Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (5570 F) as well as the bare metal visual examinations associated with NRC Bulletin 2004-01 of the upper pressurizer vessel head were completed with no evidence of leakage associated with the pressurizer spray nozzle-to-vessel weld noted during the course of the interval.

4.0 Impracticality/Burden The pressurizer vessel relief nozzle-to-vessel weld is approximately 2.8" thick. The pressurizer nozzle and vessel are clad with stainless steel on the inside diameter surface. The geometry of the nozzle along with the presence of the cladding on the inside diameter of the pressurizer result in limited access to the entire examination volume. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. The nozzle geometry tapers away from the weld resulting in limited scanning surfaces available for transducer coupling on the nozzle side of the weld resulting in additional examination limitations. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section XI. These limitations are inherent to the original design of the pressurizer vessel. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the pressurizer vessel.

4.0 Impracticality/Burden The steam generator tube sheet-to-stub barrel weld is approximately 3.3" thick. Access to scanning the complete circumference of this weld in all required directions is limited by a number of inspection covers, branch connections, a weld pad, and a vessel identification plate. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section XI. These limitations are inherent to the original design of the steam generator vessel. Conformance with the ASME Section XI requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the steam generator vessel.

The location and extent of the noted limitations precludes any additional scanning angles increasing examination coverage. The aggregate examination coverage achieved was 88.4%.
In addition to completing the required volumetric examination to the extent practical, numerous system leakage tests (ASME Section XI Category B-P and Generic Letter 88-05) at nominal system operating pressure (885 psig) and temperature (4450 F) were completed with no evidence of leakage associated with the tube sheet-to-shell weld noted during the course of the interval.

Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 Braidwood Station, Units 1 and 2 Facility Operating License Nos. NPF-72 and NPF-77 NRC Docket Nos. STN 50-456 and STN 50-457

Subject:

Relief Request 12R-50, Inservice Inspection Program Relief Regarding Examination Coverage for Second 10-Year Inservice Inspection Interval In accordance with 10 CFR 50.55a, "Codes and standards," paragraph (g)(5)(iii), Exelon Generation Company, LLC, (EGC) requests NRC approval to use a proposed alternative to the existing American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section Xl, "Rules for Inservice Inspection of Nuclear Power Plant Components," on the basis that compliance with the.specified requirements is impractical due to plant design. EGG is submitting this relief request for those ASME Section Xl weld examinations performed during the Second 10-Year Inservice Inspection (ISI) Interval where the inspection coverage achieved was less than or equal to 90%. The reduced examination coverage is due to the original design of these welds, physical obstructions, and geometric interferences.

The relief request supports the second ISI interval for both Unit 1 and Unit 2. The second ISI interval for Unit 1 began on July 29, 1998, and will end July 28, 2009. The second interval for Unit 2 began October 17, 1998, and ended October 16, 2008.

EGG requests approval of this relief request by March 31, 2010.

There are no regulatory commitments contained in this letter. If you have any questions concerning this letter, please contact Ms. Lisa A. Schofield at (630) 657-2815.

Description:==

Limited Examination Coverage Component Number:

See Attachments 1 and 2 Drawing Number:

See Attachments 1 and 2 2.0 APPLICABLE CODE EDITION AND ADDENDA:

The Second 10-Year Interval Inservice Inspection (ISI) program is based on the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV)

Code, Section Xl, 1989 with no Addenda. The 1989 Edition requires essentially 100%

examination coverage of required surfaces and volumes of various Class 1 and Class 2 components.

3.0 APPLICABLE CODE REQUIREMENT:

ASME Section Xl, 1989 Edition requires a volumetric and/or surface examination, which includes essentially 100% of the weld and the applicable base metal, for the affected examination categories.

Braidwood Station has invoked ASME Section Xl Code Case N-460, "Alternative Examination Coverage for Class 1 and Class 2 Welds, Section Xl, Division 1." Code Case N-460 states, in part, "...when the entire examination volume or area cannot be examined.., a reduction in examination coverage... may be accepted provided the reduction in coverage for that weld is less than 10%."

NRC Information Notice 98-42, "Implementation of 10 CFR 50.55a(g) Inservice Inspection Requirements," termed the reduction in coverage of less than 10% to be "essentially 100 percent." Information Notice 98-42 states, in part, "The NRC has adopted and further refined the definition of "essentially 100 percent" to mean "greater than 90 percent," which has been applied to all examinations of welds or other areas required by ASME Section XI."

4.0 IMPRACTICALITY OF COMPLIANCE:

Pursuant to 10 CFR 50.55a(g)(5)(iii), relief is requested on the basis that conformance with the specified Code requirement has been determined to be impractical. Due to the original design, physical obstructions, and geometric interferences associated with these

Braidwood Station Limited Examinations Revision 0 (Page 2 of 4) welds, it is not feasible to effectively perform examinations of 100% of the volume of these welds. Therefore, relief is requested on the basis that the Code requirements to examine essentially 100% of the welds' volume are impractical. Attaining the geometry required to achieve the Code required examination coverage would require major modifications to existing components without providing a corresponding increase in the level of quality and safety.

Attachments 1 and 2 detail the limitations for examination coverage encountered for Braidwood Station, Unit 1 and Unit 2, respectively.

5.0 BURDEN CAUSED BY COMPLIANCE:

Compliance with the examination requirements of ASME Section XI would require significant modification of plant components to remove obstructions, redesign of plant systems/components, and/or replacement of components where geometry is inherent to the component design.

6.0 PROPOSED ALTERNATIVE AND BASIS FOR USE:

In accordance with 10 CFR 50.55a(g)(5)(iii), relief is requested on the basis that the required "essentially 100%" coverage examination is impractical due to physical obstructions and limitations imposed by design, geometry, and/or physical obstructions for the components listed in Attachments 1 and 2.

Braidwood Station proposes to perform the Code required volumetric examinations to the maximum extent possible. Because of the original design of these welds, there are no alternative examination techniques currently available to increase the examination volume. There were no cases in any of the listed examination components where outside diameter surface features (i.e., weld crowns, weld shrinkage, surface roughness, etc.) could have been conditioned to maximize the coverage attained without major modification to the components.

As a minimum, all components received the required volumetric examination to the extent practical due to limited or lack of available access. There were no recordable indications requiring further evaluation noted in any of the volumetric examinations performed. For single-sided examinations of stainless steel or inconel welds, shear wave inspections were supplemented through additional scans that employed refracted longitudinal (RL) wave techniques. The examinations were conducted, and satisfactory results were confirmed, even though "essentially 100%" coverage was not attained.

Additionally, multiple VT-2 examinations were performed on the subject components throughout the interval during the required system pressure tests (examinations required by ASME Section XI and Generic Letter 88-05) and no evidence of leakage was observed at these components, providing additional assurance that the structural integrity of the subject components was maintained throughout the interval.

Braidwood Station Limited Examinations Revision 0 (Page 3 of 4)

In addition to the periodic visual inspections performed under ASME Section XI and Generic Letter 88-05, reactor coolant pressure boundary leakage is monitored through a number of other activities, which provide a high level of confidence that in the unlikely event that leakage did occur, it would be detected and proper action taken. Specifically, system leak rate limitations imposed by Technical Specification 3.4.13, "RCS Operational Leakage," as well as the reactor makeup control system, reactor cavity and containment floor drain sump monitoring, containment radiation monitoring, and containment atmospheric monitoring, provide additional assurance that any leakage would be detected prior to gross failure of these components.

7.0 DURATION OF PROPOSED ALTERNATIVE:

Relief is requested for the Second 10-Year Inservice Inspection (ISI) Interval for Braidwood Station Units 1 and 2. For the examination categories under this relief, the Second Interval for Braidwood Unit 1 began on July 29, 1998, and will end on July 28, 2009 (interval end date was adjusted as allowed by IWA-2430(d)). The Second Interval for Braidwood Unit 2 began on October 17, 1998, and concluded on October 16, 2008.

8.0 PRECEDENTS

Similar relief requests for limitations resulting in examination coverage less than 90%

have been approved for other operating units throughout the Braidwood inspection interval. Attachments 1 and 2 reference other units where similar limitations existed and the achieved examination coverage was less than 90%.

ASME Section Xl 1989 Edition with no Addenda (including Mandatory Appendices) 3.0

Applicable Code Requirement

Table IWB-2500-1, Examination Category B-A, requires volumetric examination of Item B1.40 (Head-to-Flange welds). Table IWB-2500-1 Note (2) states essentially 100% of the weld length shall be examined.

Figure IWB-2500-5 depicts the required examination volume (A-B-C-D), which includes the circumferential weld and the adjacent base metal on either side of the weld extending to a distance of one-half the thickness of the wall from the extremities of the weld crown.

ASME Section Xl Mandatory Appendix I requires ultrasonic examination of vessel welds greater than 2" thick to be conducted in accordance with ASME Section V, Article 4.

ASME Section V, Article 4 requires:

T-441.3.2.4 Extent of Scanning: Wherever feasible, the scanning of the examination volume shall be carried out from both sides of the weld on the same surface. Where the configuration or adjacent parts of the component are such that scanning from both sides is not feasible, this fact shall be included in the report of the examination.

T-441.3.2.5 Angle Beam Scanning: Wherever feasible, each examination shall be performed in two directions, i.e., approaching the weld from the opposite directions and parallel to the weld from opposite directions.

T-441.3.2.6 Scanning for Reflectors Oriented Parallel to the Weld: The angle beam search units shall be aimed at right angles to the weld axis, with the search unit manipulated so that the ultrasonic beams pass through the entire volume of weld metal.

The adjacent base metal in the examination volume must be completely scanned by two angle beams, but need not be scanned by both angle beams from both directions.

Code Case N-460, which accepts a reduction in examination coverage provided the reduction is less than 10%.

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -2 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 2 of 19) 4.0 Impracticality/Burden The reactor vessel head-to-flange weld has a nominal thickness of 7.0" and is clad with stainless steel on the inside diameter surface. The surface geometry of the flange obstructs the ultrasonic transducer movement that is needed to examine the Code required volume from the flange side. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the head/cladding interface. In addition to the examination limitations encountered due to the flange configuration and inside diameter cladding, additional examination restrictions are caused by the presence of three lifting lugs located on the reactor vessel head. These limitations preclude complete coverage of the full volume for the required scanning directions mandated by ASME Section V and Section XI. These limitations are inherent to the original design of the reactor vessel head. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the reactor vessel head.

5.0 Alternative Examinations or Testing In addition to performing the 0, 45, and 60 degree ultrasonic scans required by Appendix I, additional 30 and 40 degree ultrasonic scans were performed in lieu of the 70 degree scan as permitted by Section V, Article 4, T-441.3.2.1, to supplement coverage. The calculated volumetric coverage achieved for all combined scans was documented as 88.65%.

The Code required surface examination area (B-E as depicted in Figure IWB-2500-5) was fully achieved (100% coverage) utilizing the magnetic particle method. In addition to the required surface examination, numerous system leakage tests (ASME Section XI Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (5570F) as well as bare metal visual examinations of the upper reactor head associated with the First Revised Order EA-03-009 have been completed with no evidence of leakage associated with the reactor vessel head-to-flange weld noted during the course of the interval.

Radiography (RT) is not a desired option because RT is limited in the ability to detect expected degradation mechanisms such as service induced cracking. Additionally, RT has not been qualified through performance demonstration.

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -2 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 3 of 19) 6.0 Justification for Granting Relief No additional examinations were completed during the inspection interval; however, the aggregate examination coverage achieved (88.65%) along with the results of the completed surface examination, system pressure tests, and bare metal visual inspections performed throughout the inspection interval provide reasonable assurance that pressure boundary integrity has been maintained for this component. There were no recordable indications (other than geometric conditions) noted during any of the examinations (surface, volumetric, and visual) performed during the course of the interval.

7.0 Precedents Similar examination limitations for reactor head-to-flange welds were encountered and similar examination coverage was accepted for the following units:

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -3 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 1 of 13) 1.0 Component Weld Number:

1PZR-01-N2 Code Category/ Item:

B-D / B3.1 10 Configuration:

Pressurizer Spray Nozzle-to-Vessel Weld 2.0

Applicable Code Edition and Addenda

ASME Section Xl 1989 Edition with no Addenda (including Mandatory Appendices) 3.0

Applicable Code Requirement

Table IWB-2500-1, Examination Category B-D requires volumetric examination of Item B3.1 10 (Pressurizer Nozzle-to-Vessel welds).

Figure IWB-2500-7(b) depicts the required examination volume (A-B-C-D-E-F-G-H), which includes the actual circumferential weld and adjacent base metal on either side of the weld extending to a distance of one-half the thickness of the wall from the extremities of the weld crown.

ASME Section Xl Mandatory Appendix I requires ultrasonic examination of vessel welds greater than 2" thick to be conducted in accordance with ASME Section V, Article 4.

ASME Section V, Article 4 requires:

T-441.3.2.4 Extent of Scanning: Wherever feasible, the scanning of the examination volume shall be carried out from both sides of the weld on the same surface. Where the configuration or adjacent parts of the component are such that scanning from both sides is not feasible, this fact shall be included in the report of the examination.

T-441.3.2.5 Angle Beam Scanning: Wherever feasible, each examination shall be performed in two directions, i.e., approaching the weld from the opposite directions and parallel to the weld from opposite directions.

T-441.3.2.6 Scanning for Reflectors Oriented Parallel to the Weld: The angle beam search units shall be aimed at right angles to the weld axis, with the search unit manipulated so that the ultrasonic beams pass through the entire volume of weld metal.

The adjacent base metal in the examination volume must be completely scanned by two angle beams, but need not be scanned by both angle beams from both directions.

T-441.3.2.7 Scanning for Reflectors Oriented Transverse to the Weld: The angle beam search units shall be aimed parallel to the axis of the longitudinal and circumferential welds. The search unit shall be manipulated so that the ultrasonic beams pass through

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -3 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 2 of 13) of the examination volume. Scanning shall be done in two directions 180 degrees to each other to the extent possible. Areas blocked by geometric conditions shall be examined from at least one direction.

Code Case N-460, which accepts a reduction in examination coverage provided the reduction is less than 10%.

4.0 Impracticality/Burden The pressurizer vessel spray nozzle-to-vessel weld is approximately 2.7" thick. The pressurizer nozzle and vessel are clad with stainless steel on the inside diameter surface. The geometry of the nozzle along with the presence of the cladding on the inside diameter of the pressurizer result in limited access to the entire examination volume. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. The nozzle geometry tapers away from the weld resulting in limited scanning surfaces available for transducer coupling on the nozzle side of the weld resulting in additional examination limitations. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section XI. These limitations are inherent to the original design of the pressurizer vessel. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the pressurizer vessel.

5.0 Alternative Examinations or Testing In addition to performing the 0, 45, 60, and 70 degree scans to the extent practical as required by Appendix I, additional 30 and 40 degree scans were performed to supplement coverage. The aggregate examination coverage achieved was 69.84%.

In addition to completing the required volumetric examination to the extent practical, numerous system leakage tests (ASME Section Xl Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (5570F) as well as the bare metal visual examinations associated with NRC Bulletin 2004-01 of the upper pressurizer vessel head were completed with no evidence of leakage associated with the pressurizer spray nozzle-to-vessel weld noted during the course of the interval.

Radiography as an alternative is not feasible because access is not available for film placement. No alternative examinations are planned for the weld during the current inspection interval.

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -3 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 3 of 13) 6.0 Justification for Granting Relief No additional examinations were completed during the inspection interval; however, the examination coverage of 69.84% along with the results of the pressure test and bare metal visual inspections provide reasonable assurance that pressure boundary integrity has been maintained for this component throughout the interval.

7.0 Precedents Similar examination limitations for pressurizer spray nozzle-to-shell welds were encountered and similar examination coverage was accepted for the following units:

1PZR-01 -N3 Code Category / Item:

B-D / B3.1 10 Configuration:

Pressurizer Relief Nozzle-to-Vessel Weld 2.0

Applicable Code Edition and Addenda

ASME Section XI 1989 Edition with no Addenda (including Mandatory Appendices) 3.0

Applicable Code Requirement

Table IWB-2500-1, Examination Category B-D requires volumetric examination of Item B3.1 10 (Pressurizer Nozzle-to-Vessel welds).

Figure IWB-2500-7(b) depicts the required examination volume (A-B-C-D-E-F-G-H),

which includes the actual circumferential weld and adjacent base metal on either side of the weld extending to a distance of one-half the thickness of the wall from the extremities of the weld crown.

ASME Section Xl Mandatory Appendix I requires ultrasonic examination of vessel welds greater than 2" thick to be conducted in accordance with ASME Section V, Article 4.

ASME Section V, Article 4 requires:

T-441.3.2.4 Extent of Scanning: Wherever feasible, the scanning of the examination volume shall be carried out from both sides of the weld on the same surface. Where the configuration or adjacent parts of the component are such that scanning from both sides is not feasible, this fact shall be included in the report of the examination.

T-441.3.2.5 Angle Beam Scanning: Wherever feasible, each examination shall be performed in two directions, i.e., approaching the weld from the opposite directions and parallel to the weld from opposite directions.

T-441.3.2.6 Scanning for Reflectors Oriented Parallel to the Weld: The angle beam search units shall be aimed at right angles to the weld axis, with the search unit manipulated so that the ultrasonic beams pass through the entire volume of weld metal.

The adjacent base metal in the examination volume must be completely scanned by two angle beams, but need not be scanned by both angle beams from both directions.

T-441.3.2.7 Scanning for Reflectors Oriented Transverse to the Weld: The angle beam search units shall be aimed parallel to the axis of longitudinal and circumferential welds.

The search unit shall be manipulated so that the ultrasonic beams pass through all of the examination volume. Scanning shall be done in two directions 180 degrees to each

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -4 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 2 of 19) other to the extent possible. Areas blocked by geometric conditions shall be examined from at least one direction.

Code Case N-460, which accepts a reduction in examination coverage provided the reduction is less than 10%.

4.0 Impracticality/Burden The pressurizer vessel relief nozzle-to-vessel weld is approximately 2.7" thick. The pressurizer nozzle and vessel are clad with stainless steel on the inside diameter surface. The geometry of the nozzle along with the presence of the cladding on the inside diameter of the pressurizer result in limited access to the entire examination volume. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. The nozzle geometry tapers away from the weld resulting in limited scanning surfaces available for transducer coupling on the nozzle side of the weld resulting in additional examination limitations. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section Xl. These limitations are inherent to the original design of the pressurizer vessel. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the pressurizer vessel.

5.0 Alternative Examinations or Testing In addition to performing the 0, 45, 60, and 70 degree scans to the extent practical as required by Appendix I, additional 30 and 40 degree scans were performed to supplement coverage. The aggregate examination coverage achieved was 73.6%.

In addition to completing the required volumetric examination to the extent practical, numerous system leakage tests (ASME Section Xl Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (5570F) as well as the bare metal visual examinations associated with NRC Bulletin 2004-01 of the upper pressurizer vessel head were completed with no evidence of leakage associated with the pressurizer relief nozzle-to-vessel weld noted during the course of the interval.

Radiography as an alternative is not feasible because access is not available for film placement. No alternative examinations are planned for the weld during the current inspection interval.

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -4 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 3 of 19) 6.0 Justification for Granting Relief No additional examinations were completed during the inspection interval; however, the examination coverage of 73.6% along with the results of the pressure test and bare metal visual inspections provide reasonable assurance that pressure boundary integrity has been maintained for this component throughout the interval.

7.0 Precedents Similar examination limitations for pressurizer relief nozzle-to-shell welds were encountered and similar examination coverage was accepted for the following units:

Pipe-to-Valve Circumferential Weld 2.0

Applicable Code Edition and Addenda

ASME Section Xl 1989 Edition with no Addenda 3.0

Applicable Code Requirement

Table IWB-2500-1, Examination Category B-J, Figure IWB-2500-8(c) as supplemented by Figure 4-3 of EPRI TR-112657 Revision B-A (Reference 8.1).

Figure 4-3 of Reference 8.1 depicts the required examination volume (A-B-C-D), which includes the lower 1/3 thickness of the circumferential weld. There was no counterbore detected, so the volume 1/2" each side of the weld toes (shown in Figure 4-2 of Reference 8.1) was use to define the required examination volume.

As required by 10 CFR 50.55a, ASME Section XI 1995 Edition with 1996 Addenda Appendix VIII, Performance Demonstration for Ultrasonic Examination System was used for examination procedures, equipment, and personnel.

Code Case N-460, which accepts a reduction in examination coverage provided the reduction is less than 10%.

4.0 Impracticality/Burden This austenitic stainless steel pipe-to-valve weld and associated base materials are 4" NPS with a nominal wall thickness of 0.531" (Schedule 160) and forms the break between the "RC" and "RY" subsystem for the pressurizer spray line. Under the Braidwood Risk-Informed ISI Program, the welds associated with this particular piping segment are considered Category R-A, Item R1.20 which are not subject to any specific degradation mechanisms. This weld had been examined during the first ISI inspection interval as a "structural discontinuity" and was reselected again in the second interval under the Risk-Informed ISI Program. These examinations were performed using examination procedures and personnel qualified under the Performance Demonstration Initiative (PDI) program administered through the EPRI NDE Center, specifically, PDI-UT-2 which is qualified for manual IGSCC detection and length sizing for austenitic stainless steel welds. The PDI procedure is not qualified for the detection of flaws on the far side of single sided access examinations on austenitic stainless steel piping welds. The valve geometry tapers away from the weld resulting in limited scanning

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -5 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 2 of 7) surface available on the valve side. Volumetric examinations were also completed on five additional Category R-A, Item R1.20 welds upstream of this weld during the same refuel outage. The limited access of some welds or the presence of component supports adjacent to other welds on the line limited the population of welds for this particular segment.

5.0 Alternative Examinations or Testing In accordance with PDI-UT-2 requirements, axial and circumferential 45 degree shear wave scans and axial 60 degree refracted longitudinal wave (RL) scans of this weld were performed to the extent practical. The aggregate examination coverage achieved was 50%.

In addition to completing the required volumetric examination scans to the extent practical, numerous system leakage tests (ASME Section Xl Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (5570F)

Were completed with no evidence of leakage associated with this weld noted during the course of the interval.

The required 100% coverage was attained for the remaining five welds with no recordable indications noted in any of the welds. Since all six of these welds experience the same system conditions without any known degradation mechanism, reasonable assurance exists that there is no adverse condition associated with population of welds including the weld where limited inspection coverage was achieved.

Radiography (RT) is not a desired option because RT is limited in the ability to detect expected degradation mechanisms such as thermal fatigue cracking and stress corrosion crack initiating at the pipe inside surface. Additionally, RT has not been qualified through the performance demonstration process.

6.0 Justification for Granting Relief No additional examinations were completed during the inspection interval; however, the examination coverage of 50% along with the results of volumetric examinations performed on the other five welds in the population, as well as the numerous pressure tests completed over the course of the interval provide reasonable assurance that pressure boundary integrity has been maintained for this component.

7.0 Precedents Similar single-side limitations and associated limited examination coverage on Risk-Informed welds were encountered and accepted for the following units:

1 SG-05-SGSE-02 Code Category / Item:

R-A / R1.20, Elements not Subject to a Damage Mechanism Configuration:

Safe End-to-Nozzle Weld 2.0

Applicable Code Edition and Addenda

ASME Section Xl 1989 Edition with no Addenda 3.0

Applicable Code Requirement

Table IWB-2500-1, Examination Category C-F-i, Figure IWC-2500-7 as supplemented by Figure 4-3 of EPRI TR-112657 Revision B-A (Reference 8.1).

Figure 4-3 of Reference 8.1 depicts the required examination volume (A-B-C-D), which includes the lower 1/3 thickness of the circumferential weld. There was no counterbore detected, so the volume 1/2" each side of the weld toes (shown in Figure 4-2 of Reference 8.1) was use to define the required examination volume.

As required by 10 CFR 50.55a, ASME Section Xl 1995 Edition with 1996 Addenda Appendix VIII, Performance Demonstration for Ultrasonic Examination System was used for examination procedures, equipment, and personnel.

Code Case N-460, which accepts a reduction in examination coverage provided the reduction is less than 10%.

4.0 Impracticality/Burden The auxiliary feedwater safe end-to-nozzle weld and associated adjacent base materials are approximately 1.1" thick. This full penetration weld is Inconel 690 material but is not in contact with reactor coolant. This weld was shop fabricated and installed during the Unit 1 steam generator replacement during the Al R07 refuel outage (fall 1998). Under the Braidwood Risk-Informed ISI Program, the welds associated with this particular segment are considered Category R-A, Item R1.20, which are not subject to any specific degradation mechanisms. Due to the physical configuration of the carbon steel nozzle, which includes an adjacent taper running away from the circumferential weld, limitations preventing scanning (limitation calculated to be 35.5% for nozzle side circumferential scans) to attain coverage of 90% exist. In accordance with PDI-UT-10 requirements, 35, 40, 45, and 60 degree shear and 45 and 60 degree refracted longitudinal wave (RL) scans of this weld were performed to the extent practical. The aggregate examination coverage achieved was 79%.

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -6 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 2 of 9) 5.0 Alternative Examinations or Testing These examinations were performed using examination procedures and personnel qualified under the Performance Demonstration Initiative (PDI) program administered through the EPRI NDE Center, specifically, PDI-UT-10 which is qualified for single or dual sided manual detection and circumferential length sizing for dissimilar metal welds.

In addition to performing the required volumetric examination to the extent practical, numerous system leakage tests performed at system nominal operating pressure (1005 psig) and temperature (4430F) have been completed with no evidence of leakage associated with the auxiliary feedwater nozzle-to-safe end weld noted.

Radiography as an alternative is not feasible because access is not available for film placement. No alternative examinations are planned for the weld during the current inspection interval.

6.0 Justification for Granting Relief No additional examinations were completed during the inspection interval; however, the examination coverage of 79% along with the results of the pressure tests assure boundary integrity has been maintained for this component.

7.0 Precedents None.

__.DATE 10/1512007 DouglajGrftnewold, Level HI The above referenced Dissimilar Metal Weld was examined in both the Axial and Circumferential directions. The Axial scans were performed utilizing 450 Shear, 450 and 600 RL search units. Due to the ID/OD ratio of the component, the Circ scans were performed with 350 Shear and 40° RL search units. No exam was performed looking upstream due to the nozzle configuration. The 350 Shear wave exam was performed on the nozzle side as a supplemental exam and no credit for coverage was taken on the nozzle side with this search unit.

Below is the coverage calculation:

2RV-03-001 Code Category / Item:

B-A / B1.40 Configuration:

Reactor Vessel Head-to-Flange Weld 2.0

Applicable Code Edition and Addenda

ASME Section XI 1989 Edition with no Addenda (including Mandatory Appendices) 3.0

Applicable Code Requirement

Table IWB-2500-1, Examination Category B-A, requires volumetric examination of Item B1.40 (Head-to-Flange welds). Table IWB-2500-1 Note (2) states essentially 100% of the weld length shall be examined.

Figure IWB-2500-5 depicts the required examination volume (A-B-C-D), which includes the circumferential weld and the adjacent base metal on either side of the weld extending to a distance of one-half the thickness of the wall from the extremities of the weld crown.

ASME Section Xl Mandatory Appendix I requires ultrasonic examination of vessel welds greater than 2" thick to be conducted in accordance with ASME Section V, Article 4.

ASME Section V, Article 4 requires:

T-441.3.2.4 Extent of Scanning: Wherever feasible, the scanning of the examination volume shall be carried out from both sides of the weld on the same surface. Where the configuration or adjacent parts of the component are such that scanning from both sides is not feasible, this fact shall be included in the report of the examination.

T-441.3.2.5 Angle Beam Scanning: Wherever feasible, each examination shall be performed in two directions, i.e., approaching the weld from the opposite directions and parallel to the weld from opposite directions.

T-441.3.2.6 Scanning for Reflectors Oriented Parallel to the Weld: The angle beam search units shall be aimed at right angles to the weld axis, with the search unit manipulated so that the ultrasonic beams pass through the entire volume of weld metal.

The adjacent base metal in the examination volume must be completely scanned by two angle beams, but need not be scanned by both angle beams from both directions.

Code Case N-460, which accepts a reduction in examination coverage provided the reduction is less than 10%.

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -2 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 2 of 13) 4.0 Impracticality/Burden The reactor vessel head-to-flange weld has a nominal thickness of 7.0" and is clad with stainless steel on the inside diameter surface. The surface geometry of the flange obstructs the ultrasonic transducer movement that is needed to examine the Code required volume from the flange side. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. In addition to the examination limitations encountered due to the flange configuration and inside diameter cladding, additional examination restrictions are caused by the presence of three lifting lugs located on the reactor vessel head. These limitations preclude complete coverage of the full volume for the required scanning directions mandated by ASME Section V and Section XI. These limitations are inherent to the original design of the reactor vessel head. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the reactor vessel head.

5.0 Alternative Examinations or Testing In addition to performing the 0, 45, and 60 degree ultrasonic scans required by Appendix I, additional 30 and 40 degree ultrasonic scans were performed in lieu of the 70 degree scan as permitted by Section V, Article 4, T-441.3.2.1 to supplement coverage. The calculated volumetric coverage achieved for all combined scans was documented as 87.64%.

The Code required surface examination area (B-E as depicted in Figure IWB-2500-5) was fully achieved (100% coverage) utilizing the magnetic particle method. In addition to the required surface examination, numerous system leakage tests (ASME Section Xl Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (5570F) as well as bare metal visual examinations of the upper reactor head associated with the First Revised Order EA-03-009 have been completed with no evidence of leakage associated with the reactor vessel head-to-flange weld noted during the course of the interval.

Radiography (RT) is not a desired option because RT is limited in the ability to detect expected degradation mechanisms such as service induced cracking. Additionally, RT has not been qualified through performance demonstration.

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -2 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 3 of 13) 6.0 Justification for Granting Relief No additional examinations were completed during the inspection interval; however, the aggregate examination coverage achieved 87.64% along with the results of the completed surface examination, system pressure tests, and bare metal visual inspections performed throughout the inspection interval provide reasonable assurance that pressure boundary integrity has been maintained for this component. There were no indications noted during any of the examinations (surface, volumetric, and visual) performed during the course of the interval.

7.0 Precedents Similar examination limitations for reactor head-to-flange welds were encountered and similar examination coverage was accepted for the following units:

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -3 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 1 of 24) 1.0 Component Weld Number:

2PZR-01-N2 Code Category/ Item:

B-D / B3.1 10 Configuration:

Pressurizer Spray Nozzle-to-Vessel Weld 2.0

Applicable Code Edition and Addenda

ASME Section Xl 1989 Edition with no Addenda (including Mandatory Appendices) 3.0

Applicable Code Requirement

Table IWB-2500-1, Examination Category B-D requires volumetric examination of Item B3.1 10 (Pressurizer Nozzle-to-Vessel welds).

Figure IWB-2500-7(b) depicts the required examination volume (A-B-C-D-E-F-G-H),

which includes the actual circumferential weld and adjacent base metal on either side of the weld extending to a distance of one-half the thickness of the wall from the extremities of the weld crown.

ASME Section Xl Mandatory Appendix I requires ultrasonic examination of vessel welds greater than 2" thick to be conducted in accordance with ASME Section V, Article 4.

ASME Section V, Article 4 requires:

T-441.3.2.4 Extent of Scanning: Wherever feasible, the scanning of the examination volume shall be carried out from both sides of the weld on the same surface. Where the configuration or adjacent parts of the component are such that scanning from both sides is not feasible, this fact shall be included in the report of the examination.

T-441.3.2.5 Angle Beam Scanning: Wherever feasible, each examination shall be performed in two directions, i.e., approaching the weld from the opposite directions and parallel to the weld from opposite directions.

T-441.3.2.6 Scanning for Reflectors Oriented Parallel to the Weld: The angle beam search units shall be aimed at right angles to the weld axis, with the search unit manipulated so that the ultrasonic beams pass through the entire volume of weld metal.

The adjacent base metal in the examination volume must be completely scanned by two angle beams, but need not be scanned by both angle beams from both directions.

T-441.3.2.7 Scanning for Reflectors Oriented Transverse to the Weld: The angle beam search units shall be aimed parallel to the axis of the longitudinal and circumferential welds. The search unit shall be manipulated so that the ultrasonic beams pass through of the examination volume. Scanning shall be done in two directions 180 degrees to

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -3 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 2 of 24) each other to the extent possible. Areas blocked by geometric conditions shall be examined from at least one direction.

Code Case N-460, which accepts a reduction in examination coverage provided the reduction is less than 10%.

4.0 Impracticality/Burden The pressurizer vessel spray nozzle-to-vessel weld is approximately 2.7" thick. The pressurizer nozzle and vessel are clad with stainless steel on the inside diameter surface. The geometry of the nozzle along with the presence of the cladding on the inside diameter of the pressurizer result in limited access to the entire examination volume. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. The nozzle geometry tapers away from the weld resulting in limited scanning surfaces available for transducer coupling on the nozzle side of the weld resulting in additional examination limitations. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section XI. These limitations are inherent to the original design of the pressurizer vessel. Conformance with the ASME Section XI requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the pressurizer vessel.

5.0 Alternative Examinations or Testing In addition to performing the 0, 45 (recorded as 46 degrees in coverage calculation data), 60, and 70 degree scans to the extent practical as required by Appendix I, additional 30 and 40 degree scans were performed to supplement coverage. The aggregate examination coverage achieved was 83.64%.

In addition to completing the required volumetric examination to the extent practical, numerous system leakage tests (ASME Section XI Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (5570F) as well as the bare metal visual examinations associated with NRC Bulletin 2004-01 of the upper pressurizer vessel head were completed with no evidence of leakage associated with the pressurizer spray nozzle-to-vessel weld noted during the course of the interval.

Radiography as an alternative is not feasible because access is not available for film placement.

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -3 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 3 of 24) 6.0 Justification for Granting Relief No additional examinations were completed during the inspection interval; however, the examination coverage of 83.64% along with the results of the pressure test and bare metal visual inspections provide reasonable assurance that pressure boundary integrity has been maintained for this component throughout the interval.

7.0 Precedents Similar examination limitations for pressurizer spray nozzle -to-shell welds were encountered and similar examination coverage was accepted for the following units:

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -4 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 1 of 29) 1.0 Component Weld Number:

2PZR-01-N3 Code Category / Item:

B-D / B3.1 10 Configuration:

Pressurizer Relief Nozzle-to-Vessel Weld 2.0

Applicable Code Edition and Addenda

ASME Section XI 1989 Edition with no Addenda (including Mandatory Appendices) 3.0

Applicable Code Requirement

Table IWB-2500-1, Examination Category B-D requires volumetric examination of Item B3. 110 (Pressurizer Nozzle-to-Vessel welds).

Figure IWB-2500-7(b) depicts the required examination volume (A-B-C-D-E-F-G-H),

which includes the actual circumferential weld and adjacent base metal on either side of the weld extending to a distance of one-half the thickness of the wall from the extremities of the weld crown.

ASME Section XI Mandatory Appendix I requires ultrasonic examination of vessel welds greater than 2" thick to be conducted in accordance with ASME Section V, Article 4.

ASME Section V, Article 4 requires:

T-441.3.2.4 Extent of Scanning: Wherever feasible, the scanning of the examination volume shall be carried out from both sides of the weld on the same surface. Where the configuration or adjacent parts of the component are such that scanning from both sides is not feasible, this fact shall be included in the report of the examination.

T-441.3.2.5 Angle Beam Scanning: Wherever feasible, each examination shall be performed in two directions, i.e., approaching the weld from the opposite directions and parallel to the weld from opposite directions.

T-441.3.2.6 Scanning for Reflectors Oriented Parallel to the Weld: The angle beam search units shall be aimed at right angles to the weld axis, with the search unit manipulated so that the ultrasonic beams pass through the entire volume of weld metal.

The adjacent base metal in the examination volume must be completely scanned by two angle beams, but need not be scanned by both angle beams from both directions.

T-441.3.2.7 Scanning for Reflectors Oriented Transverse to the Weld: The angle beam search units shall be aimed parallel to the axis of the longitudinal and circumferential welds. The search unit shall be manipulated so that the ultrasonic beams pass through of the examination volume. Scanning shall be done in two directions 180 degrees to

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -4 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 2 of 29) each other to the extent possible. Areas blocked by geometric conditions shall be examined from at least one direction.

Code Case N-460, which accepts a reduction in examination coverage provided the reduction is less than 10%.

4.0 Impracticality/Burden The pressurizer vessel relief nozzle-to-vessel weld is approximately 2.8" thick. The pressurizer nozzle and vessel are clad with stainless steel on the inside diameter surface. The geometry of the nozzle along with the presence of the cladding on the inside diameter of the pressurizer result in limited access to the entire examination volume. The propagation for the ultrasonic beam was in the shear mode. Normally this mode would allow the ultrasonic beam to reflect off the inside surfaces and create a two-beam axis at right angles to each other; however, the presence of the stainless steel cladding precludes the ultrasound beams from reflecting at the inside diameter from the shell/cladding interface. The nozzle geometry tapers away from the weld resulting in limited scanning surfaces available for transducer coupling on the nozzle side of the weld resulting in additional examination limitations. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section XI. These limitations are inherent to the original design of the pressurizer vessel. Conformance with the ASME Section Xl requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the pressurizer vessel.

5.0 Alternative Examinations or Testing In addition to performing the 0, 45 (recorded as 46 degrees in coverage calculation data), 60, and 70 degree scans to the extent practical as required by Appendix I, additional 30 and 40 degree scans were performed to supplement coverage. The aggregate examination coverage achieved was 80.9%.

In addition to completing the required volumetric examination to the extent practical, numerous system leakage tests (ASME Section XI Category B-P and Generic Letter 88-05) at nominal system operating pressure (2235 psig) and temperature (557°F) as well as the bare metal visual examinations associated with NRC Bulletin 2004-01 of the upper pressurizer vessel head were completed with no evidence of leakage associated with the pressurizer relief nozzle-to-vessel weld noted during the course of the interval.

Radiography as an alternative is not feasible because access is not available for film placement.

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -4 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 3 of 29) 6.0 Justification for Granting Relief No additional examinations were completed during the inspection interval; however, the examination coverage of 80.9% along with the results of the pressure test and bare metal visual inspections provide reasonable assurance that pressure boundary integrity has been maintained for this component throughout the interval.

7.0 Precedents Similar examination limitations for pressurizer relief nozzle-to-shell welds were encountered and similar examination coverage was accepted for the following units:

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -5 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 1 of 7) 1.0 Component Weld Number:

2SG-01-SGC-02 Code Category / Item:

C-A / C1.30 Configuration:

Steam Generator Tube Sheet-to-Stub Barrel Weld 2.0

Applicable Code Edition and Addenda

ASME Section XI 1989 Edition with no Addenda (including Mandatory Appendices) 3.0

Applicable Code Requirement

Table IWC-2500-1, Examination Category C-A requires volumetric examination of Item C1.30 (Tube Sheet-to-Shell welds). Table IWC-2500-1 Note (1) states essentially 100%

of the weld length shall be examined.

Figure IWC-2500-2 depicts the required examination volume (E-F-G-H), which includes the actual circumferential weld and adjacent base metal 1/2" on either side of the weld from the extremities of the weld crown.

ASME Section Xl Mandatory Appendix I requires ultrasonic examination of vessel welds greater than 2" thick to be conducted in accordance with ASME Section V, Article 4.

ASME Section V, Article 4 requires:

T-441.3.2.4 Extent of Scanning: Wherever feasible, the scanning of the examination volume shall be carried out from both sides of the weld on the same surface. Where the configuration or adjacent parts of the component are such that scanning from both sides is not feasible, this fact shall be included in the report of the examination.

T-441.3.2.5 Angle Beam Scanning: Wherever feasible, each examination shall be performed in two directions, i.e., approaching the weld from the opposite directions and parallel to the weld from opposite directions.

T-441.3.2.6 Scanning for Reflectors Oriented Parallel to the Weld: The angle beam search units shall be aimed at right angles to the weld axis, with the search unit manipulated so that the ultrasonic beams pass through the entire volume of weld metal.

The adjacent base metal in the examination volume must be completely scanned by two angle beams, but need not be scanned by both angle beams from both directions.

T-441.3.2.7 Scanning for Reflectors Oriented Transverse to the Weld: The angle beam search units shall be aimed parallel to the axis of the longitudinal and circumferential welds. The search unit shall be manipulated so that the ultrasonic beams pass through of the examination volume. Scanning shall be done in two directions 180 degrees to

ISI Program Plan Braidwood Station Units 1 & 2, Second Interval 10 CFR 50.55a RELIEF REQUEST 12R-50 -5 Braidwood Station Unit 1 Limited Examinations Revision 0 (Page 2 of 7) each other to the extent possible. Areas blocked by geometric conditions shall be examined from at least one direction.

Code Case N-460, which accepts a reduction in examination coverage provided the reduction is less than 10%.

4.0 Impracticality/Burden The steam generator tube sheet-to-stub barrel weld is approximately 3.3" thick. Access to scanning the complete circumference of this weld in all required directions is limited by a number of inspection covers, branch connections, a weld pad, and a vessel identification plate. These factors result in limited examination coverage from the scan directions required by ASME Section V and Section XI. These limitations are inherent to the original design of the steam generator vessel. Conformance with the ASME Section XI requirements for essentially 100% of the volumetric coverage would require extensive structural modifications to the steam generator vessel.

5.0 Alternative Examinations or Testing The required 0, 45, and 60 degree scans required by Appendix I, were completed to the extent practical. The location and extent of the noted limitations precludes any additional scanning angles increasing examination coverage. The aggregate examination coverage achieved was 88.4%.

In addition to completing the required volumetric examination to the extent practical, numerous system leakage tests (ASME Section XI Category B-P and Generic Letter 88-05) at nominal system operating pressure (885 psig) and temperature (4450F) were completed with no evidence of leakage associated with the tube sheet-to-shell weld noted during the course of the interval.

Radiography as an alternative is not feasible because access is not available for film placement.

6.0 Justification for Granting Relief No additional examinations were completed during the inspection interval; however, the examination coverage of 88.4% along with the results of the completed pressure tests provide reasonable assurance that pressure boundary integrity has been maintained for this component throughout the interval.
