Reference:

Correspondence from Marco Ruvalcaba, STP Nuclear Operating Company, to NRC Document Control Desk, "Request for Relief from ASME Section Xl Requirements for Weld Examinations (Relief Request RR-ENG-2-55)," dated July 29, 2010 (NOC-AE-1 0002578) (ML102240169) Pursuant to 10 CFR 50.55a(g)(5)(iii), STP Nuclear Operating Company (STPNOC) submits an amended request for relief from ASME Section Xl requirements for weld examination on the basis of impracticality. ASME Section Xl Tables IWB-2500-1 and IWC-2500-1 require inservice inspection of Class 1 and Class 2 component welds by nondestructive examination. 100% examination coverage of these welds during the second ten-year inspection interval was impractical because of component configuration and geometry, and because of the limitations of the examination equipment and techniques used to perform these examinations. The attached discussion includes a list of the affected welds for which relief is requested, the amount of coverage obtained, and the basis and justification for their acceptability. STPNOC requests NRC review and approval of this request by January 31, 2011. This date is flexible. This addendum provides enhanced tables with references to the requested ultrasonic examination results. Sketches showing areas where ultrasonic examinations could not be performed are included in the individual ultrasonic examination reports. Changes in the text are indicated by change bars. There are no commitments included with this request. If there are any questions, please contact either Mr. P. L. Walker at (361) 972-8392 or me at (361) 972-7904. arco aRuv

Attachment NOC-AE-1 0002604 Page 1 of 8 SOUTH TEXAS PROJECT UNITS I AND 2 AMENDED REQUEST FOR RELIEF FROM ASME SECTION XI CODE REQUIREMENTS FOR WELD EXAMINATIONS (RELIEF REQUEST RR-ENG-2-55) Reference Code: ASME Boiler and Pressure Vessel Code, Section Xl 1989 Edition No Addenda A. Components for Which Exemption is Requested (a) Name and Identification Number: Component welds as listed in the attached tables. / (b) Function: Various (Refer to applicable sections of the South Texas Project Updated Final Safety Analysis Report for specifics) (c) Class: ASME Code Class,1 or Class 2 as specified in the attached tables B. Code Requirement from Which Relief is Requested ASME Section Xl Code Table IWB-2500-1 and Table IWC-2500-1 specify the examination method and extent of coverage for nondestructive examination of welds. Relief from full volumetric or surface examination coverage requirements of the Section Xl Code is to be requested when the obtained coverage is 90% or less. The welds for which relief is requested are listed in the attached tables. Welds with volumetric or surface examination coverage reduced less than 10% are considered to have essentially 100% coverage in accordance with ASME Section Xl Code Case N-460. C. Basis for Relief from Code Requirements Obtaining required examination coverage of welds listed in the appended tables was found to be impractical due to various factors, including: " Component configuration, Geometry, and Examination equipment and techniques utilized for the examinations. STPNOC requests relief from full examination coverage requirements for the welds listed based on the impracticality of achieving required coverage. D. Alternate Examination No alternate examinations are proposed for the welds for which relief is requested.

Attachment NOC-AE-1 0002604 Page 2 of 8 E. Justification for Granting Relief 100% examination coverage of these welds is impractical because of component configuration and geometry, and because of the limitations of the examination equipment and techniques used to perform these examinations. However, volumetric and surface examinations of accessible locations will continue as required. The following tables reference the weld results summaries for the components examined. The summaries include sketches, drawings, etc., describing the ultrasonic coverage obtained (scan paths, etc.) and why the limitations cited have restricted the overall coverage obtained. Only those reports for components where ultrasonic testing was performed are provided, i.e., where coverage was volumetric. F. Implementation Schedule STPNOC requests that the Nuclear Regulatory Commission grant relief from the referenced nondestructive examination requirements pursuant to 10 CFR 50.55a(g)(6)(i). Approval of this application is requested by January 31, 2011; however, this date is flexible. G. Additional Information Reactor Vessel Weld Results Summary

SUMMARY

OF PRESERVICE EXAMINATION LIMITATIONS The following tables provide details on the limitations which were encountered during the preservice examinations (PSI) at the South Texas Project Electric Generating Station (STP), Unit 1. The areas are listed in a table for that particular vessel or piping system and are arranged in the same order as the SwRI PSI plan. Each table of this summary provides the following information as described: Column 1 - Class/Category/Item No./Examination Requirement Identifies the ASME Section XI Code class, category, item number and exami-nation requirement (volumetric or surface) for the specific examination area listed in Column 2. This information is derived from tables IWB-2500-1 and IWC-2500-1 of the 1980 Edition of ASME Section XI (with Addenda through Winter 1981). Column 2-Line No./Subassembly Weld Identification Weld ID Figure Weld Configuration Examination Method Provides information for each examination are by line number (piping) or sub-assembly number (vessel), unique weld identification number, SwRI weld ID figure reference, weld configuration (pipe-to-tee, head-to-shell, etc.), and examination method (UT, UT/PT, or UT/MT). Column 3 - Exam Type Lists the methods of examinations used for each area by specific angles for UT (0., 45, 45T, 60, 60T) and surface technique (MT or PT) if required. Column 4 - % Coverage The extent of coverage for each exam type is expressed in percentages based on the examination volume/area required in Section XI. Depending on method, the percentage coverage may be represented in more than one way. Surface methods are the simplest and are expressed as a percentage of the required surface area receiving no coverage and the remaining balance from 100 percent as the total coverage. Ultrasonic coverage is first expressed for each exam type as a percentage of the volume receiving no coverage, angle beam coverage in 1 direction only, and angle beam coverage in 2 directions. Thege percentages are then used to com-pute the effective coverage for that exam type. In the case of 0 degree, the effective coverage is equal to the balance of 100 percent minus the percentage receiving no coverage. The effective coverage for angle beam is calculated from the following formula: K-17

C = A + 2*B (Effective Coverage formula, angle beam) 2 Where A = 1 Direction only percentage B - 2 Direction percentage Examples: (1) None 0% 1 Direction 0% 2 Direction 100% C = 0 + 2*100 = 100% Effective Coverage 2 (2) None 0% 1 Direction 100% 2 Direction 0% c = 100 + 2*0 2 50% Effective Coverage (3) None 50% 1 Direction 50% 2 Direction 0% C = 50 + 2*0 = 25% Effective-Coverage 2 The total UT coverage is then expressed as the average of the effective cover-age percentages for each UT exam type. Each UT exam type is considered as equal weight in the calculation of the average. This method for reporting UT coverage as a single percentage for all UT exam types was the preferred method by HL&P for identifying UT examination area limitations. Column 5 - Limitation A description of the type of limitation and primary reason for why the coverage was limited is provided in this column. Column 6 - Fabrication NDE This column describes the fabrication/construction NDE that was performed to satisfy the ASME Section III requirements for that component. K-18

SUMMARY

OF PRESERVICE EXAMINATION LIMITATIONS The following tables provide details on the limitations which were encountered during the preservice examinations (PSI) at the South Texas Project Electric Generating Station (STP), Unit 1. The areas are listed in a table for that particular vessel or piping system and are arranged in the same order as the SwRI PSI plan. Each table of this summary provides the following information as described: Column 1 - Class/Category/Item No./Examination Requirement Identifies the ASME Section XI Code class, category, item number and exami-nation requirement (volumetric or surface) for the specific examination area listed in Column 2. This information is derived from tables IWB-2500-1 and IWC-2500-1 of the 1980 Edition of ASME Section XI (with Addenda through Winter 1981). Column 2 Line No./Subassembly Weld Identification Weld ID Figure Weld Configuration Examination Method Provides information for each examination are by line number (piping) or sub-assembly number (vessel), unique weld identification number, SwRI weld ID figure reference, weld configuration (pipe-to-tee, head-to-shell, etc.), and examination method (UT, UT/PT, or UT/MT). Column 3 - Exam Type Lists the methods of examinations used for each area by specific angles for UT (0, 4.5,

45T, 60, 60T) and surface technique (MT or PT) if required.

Column 4 - % Coverage The extent of coverage for each exam type is expressed in percentages based on the examination volume/area required in Section XI. Depending on method, the percentage coverage may be represented in more than one way. Surface methods are the simplest and are expressed as a percentage of the required surface area receiving no coverage and the remaining balance from 100 percent as the total coverage. Ultrasonic coverage is first expressed for each exam type as a percentage of the volume receiving no coverage, angle beam coverage in I direction only, and angle beam coverage in 2 directions. Thege percentages are then used to com-pute the effective coverage for that exam type. In the case of 0 degree, the effective coverage is equal to the balance of 100 percent minus the percentage receiving no coverage. The effective coverage for angle beam is calculated from the following formula: K-17

SUMMARY

OF PRESERVICE EXAMINATION LIMITATIONS The following tables provide details on the limitations which were encountered during the preservice examinations (PSI) at the South Texas Project Electric Generating Station (STP), Unit 1. The areas are listed in a table for that particular vessel or piping system and are arranged in the same order as the SwRI PSI plan. Each table of this summary provides the following information as described: Column 1 - Class/Category/Item No./Examination Requirement Identifies the ASME Section XI Code class, category, item number and exami-nation requirement (volumetric or surface) for the specific examination area listed in Column 2. This information is derived from tables IWB-2500-1 and IWC-2500-1 of the 1980 Edition of ASME Section XI (with Addenda through Winter 1981). Column 2 - Line No./Subassembly Weld Identification Weld ID Figure Weld Configuration Examination Method Provides information for each examination are by line number (piping) or sub-assembly number (vessel), unique weld identification number, SwRI weld ID figure reference, weld configuration (pipe-to-tee, head-to-shell, etc.), and examination method (UT, UT/PT, or UT/MT). Column 3 - Exam Type Lists the methods of examinations used for each area by specific angles for UT (0, 45,

45T, 60, 60T) and surface technique (MT or PT) if required.

Column 4 - % Coverage The extent of coverage for each exam type is expressed in percentages based on the examination volume/area required in Section XI. Depending on method, the percentage coverage may be represented in more than one way. Surface methods are the simplest and are expressed as a percentage of the required surface area receiving no coverage and the remaining balance from 100 percent as the total coverage. Ultrasonic coverage is first expressed for each exam type as a percentage of the volume receiving no coverage, angle beam coverage in 1 direction only, and angle beam coverage in 2 directions. Thege percentages are then used to com-pute the effective coverage for that exam type. In the case of 0 degree, the effective coverage is equal to the balance of 100 percent minus the percentage receiving no coverage. The effective coverage for angle beam is calculated from the following formula: K-17

C = A + 2*B (Effective Coverage formula, angle beam) 2 Where A = 1 Direction only percentage B - 2 Direction percentage Examples: (1) None 0% 1 Direction 0% 2 Direction 100% c. 0 + 2*100 = 2 100% Effective Coverage (2) None 0% 1 Direction 100% 2 Direction 0% c = 100 + 2*0 = 2 50% Effective Coverage (3) None 50% 1 Direction 50% 2 Direction 0% C = 50 + 2*0 = 25% Effective Coverage 2 The total UT coverage is then expressed as the average of the effective cover-age percentages for each UT exam type. Each UT exam type is considered as equal weight in the calculation of the average. This method for reporting UT coverage as a single percentage for all UT exam types was the preferred method by KL&P for identifying UT examination area limitations. Column 5 - Limitation A description of the type of limitation and primary reason for why the coverage was limited is provided in this column. j Column 6 - Fabrication NDE This column describes the fabrication/construction NDE that was performed to satisfy the ASME Section III requirements for that component.

SUMMARY

OF PRESERVICE EXAMINATION LIMITATIONS The following tables provide details on the limitations which were encountered during the preservice examinations (PSI) at the South Texas Project Electric Generating Station (STP), Unit 1. The areas are listed in a table for that particular vessel or piping system and are arranged in the same order as the SwRI PSI plan. Each table of this summary-provideS the following information as described:' Column 1 - Class/Category/Item No./Examination Requirement Identifies the ASME Section XI Code class, category, item number and exami-nation requirement (volumetric or surface) for the specific examination area listed in Column 2. This information is derived from tables IWB-2500-1 and IWC-2500-1 of the 1980 Edition of ASME Section XI (with Addenda through Winter 1981). Column 2 - Line No./Subassembly' Weld Identification Weld ID Figure Weld Configuration Examination Method Provides information for each examination are by line number (piping) or sub-assembly number (vessel), unique weld'identification number, SwRI weld ID figure reference, weld configuration (pipe-to-tee, head-to-shell, etc.), and examination method (UT, UT/PT, or UT/MT). Column 3 Exam Type Lists the methods of examinations used for each area by specific angles for UT (0, 45, 45T, 60, 60T) and surface technique (MT or PT) if required. Column 4 - % Coverage The extent of coverage for each exam type is expressed in percentages based on the examination volume/area required in Section XI. Depending on method, the percentage coverage may be represented in more than one way. Surface methods are the simplest and are expressed as a percentage of the required surface area receiving no coverage and the remaining balance from 100 percent as the total coverage. Ultrasonic coverage is first expressed for each exam type as a percentage of the volume receiving no coverage, angle beam coverage in I direction only, and angle beam coverage in 2 directions. Thege percentages are then used to com-pute the effective coverage for that exam type. In the case of 0 degree, the effective coverage is equal to the balance of 100 percent minus the percentage receiving no coverage. The effective coverage for angle beam is calculated from the following formula: K-17

C = A + 2*B (Effective Coverage formula, angle beam) 2 Where A = 1 Direction-only percentage B = 2 Direction percentage Examples: (1) None 0% 1 Direction 0% 2 Direction 100% C = 0 + 2*100 = 2 100% Effective Coverage (2) None 0% I Direction 100% 2 Direction 0% C = 100 + 2*0 = 50% Effective Coverage 2 (3) None 50% 1 Direction 50% 2 Direction 0% C = 50 + 2*0 = 25% Effective Coverage 2 The total UT coverage is then expressed as the average of the effective cover-age percentages for each UT exam type. Each UT exam type is considered as equal weight in the calculation of the average. This method for reporting UT coverage as a single percentage for all UT exam types was the preferred method by HL&P for identifying UT examination area limitations. Column 5 - Limitation A description of the type of limitation and primary reason for why the coverage was limited is provided in this column. Column 6 - Fabrication NDE This column describes the fabrication/construction NDE that was performed to satisfy the ASME Section III requirements for that component. K-18

SUMMARY

OF PRESERVICE EXAMINATION LIMITATIONS The following tables provide details on the limitations which were encountered during the Preservice Examinations (PSI) at the South Texas Project Electric Generating Station (STP), Unit 2. Each table of this summary provides the followinginformation as described: Column 1 Class/Category/Item No./Examination Requirement Identifies the ASME Section XI Code Class, Category, Item Number and Examination Requirement (volumetric or surface) for the specific examination area listed in Column 2. This information is derived from Tables IWB-2500-1 and IWC-2500-1 of the 1980 Edition of ASME Section XI (with Addenda through Winter 1981). Column 2 Line No./Subassembly Weld Identification Weld ID Figure Weld Configuration Examination Method Provides information for each examination area by line number (piping) or subassembly n-umber (vessel), unique weld identification number, SWRI weld ID figure reference, weld configuration (pipe-to-tee, head-to-shell, etc.), And examination method (UT, UT/PT, or UT/MT). Column 3 Exam Type Lists the Methods of Examinations used for each area by specific angles for UT (0, 45, 45T, 60, 60T) and surface technique (MT or PT) if required. Column 4 % Coverage The extent of coverage for each exam type is expressed in percentages based on the examination volume/area required in Section XI. Depending on method, the percentage coverage may be represented in more than one way. Surface methods are the simplest and are expressed as a percentage of the required surface area receiving no coverage and the remaining balance from 100% as the total coverage. iii

Column 5 Limitation A description of the type of limitation and primary reason for why the coverage was limited is provided in this column. Column 6 Fabrication NDE This column describes the fabrication/construction NDE that was performed to satisfy the ASME Section III requirements for that component. 0 V

Ultrasonic coverage is first expressed for each exam type as a percentage of the volume receiving no coverage, angle beam coverage in 1 direction only, and angle beam coverage in 2 directions. These percentages are then used to compute the effective coverage for that exam type. In the case of 0 degree, the effective coverage is equal to the balance of 100% minus the percentage receiving no coverage. The effective coverage for angle beam is calculated from the following formula: a + 2*b c f (effective coverage formula, angle beam) 2 where a = 1 direction only percentage b = 2 direction percentage examples: (1) none 1 dir 2dir 0% 0% 100% 0 + 2*100 c = 100% effective coverage 2 (2) none 1 dir 2 dir 0% 100% 0% 100 + 2*0 c = 50% effective coverage 2 (3) none I dir 2 dir 50% 50% 0% 50 + 2*0 c = = 25% effective coverage 2 The total UT coverage is then expressed as the average of the effective coverage percentages for each UT exam type. Each UT exam type is considered as equal weight in the calculation of the average. This method for reporting UT coverage as a single percentage for all UT exam types was the preferred method by HL&P for identifying UT examination area limitations. iv

SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION, UNIT 2

SUMMARY

OF PRESERVICE EXAMINATION LIMITATIONS The following tables provide details on the limitations which were encountered during the Preservice Examinations (PSI) at the South Texas Project Electric Generating Station (STP), Unit 2. Each table of this summary provides the following information as described: Column 1 Class/Category/Item No./Examination Requirement Identifies the ASME Section XI Code Class, Category, Item Number and Examination Requirement (volumetric or surface) for the specific examination area listed in Column 2. This information is derived from Tables IWB-2500-1 and IWC-2500-1 of the 1980 Edition of ASME Section XI (with Addenda through Winter 1981). Column 2 Line No./Subassembly Weld Identification Weld ID Figure Weld Configuration Examination Method Provides information for each examination area by line number (piping) or subassembly number (vessel), unique weld identification number, SWRI weld ID figure reference, weld configuration (pipe-to-tee, head-to-shell, etc.), And examination method (UT, UT/PT, or UT/MT). Column 3 Exam Type Lists the Methods of Examinations used for each area by specific angles for UT (0, 45, 45T, 60, 60T) and surface technique (MT or PT) if required. Column 4 % Coverage The extent of coverage for each exam type is expressed in percentages based on the examination volume/area required in Section XI. Depending on method, the percentage coverage may be represented in more than one way. Surface methods are the simplest and are expressed as a percentage of the required surface area receiving no coverage and the remaining balance from 100% as the total coverage. i.i

Column 5 Limitation A description of the type of limitation and primary reason for why the coverage was limited is provided in this column. Column 6 Fabrication NDE This column describes the fabrication/construction NDE that was performed to satisfy the ASME Section HI requirements for that component. V

Ultrasonic coverage is first expressed for each exam type as a percentage of the volume receiving no coverage, angle beam coverage in 1 direction only, and angle beam coverage in 2 directions. These percentages are then used to compute the effective coverage for that exam type. In the case of 0 degree, the effective coverage is equal to the balance of 100% minus the percentage receiving no coverage. The effective coverage for angle beam is calculated from the following formula. a + 2*b c =------------ (effective coverage formula, angle beam) 2 where a = 1 direction only percentage b = 2 direction percentage examples: (1) none 1 dir 2 dir 0% 0% 100% 0 + 2*100 c = = 100% effective coverage 2 (2) none 1 dir 2 dir 0% 100% 0% 100 + 2*0 c

.- = 50% effective coverage 2

(3) none I dir 2 dir 50% 50% 0% 50 + 2*0 c =----------- = 25% effective coverage 2 The total UT coverage is then expressed as the average of the effective coverage percentages for each UT exam type. Each UT exam type is considered as equal weight in the calculation of the average. This method for reporting UT coverage as a single percentage for all UT exam types was the preferred method by HL&P for identifying UT examination area limitations. iv
