1-5 151 Program Plan Revision 0

151 Program Plan Braidwood Station Units 1 & 2, Third Interval

1.2 Background

The Commonwealth Edison Company, now known commercially as Exelon Generation Company (EGC) or Exelon, obtained Construction Permits to build Braidwood Station Units 1 and 2 on December 31, 1975, for Unit 1, CPPR-132, and for Unit 2, CPPR-133. The Docket Numbers assigned to Braidwood Station are STN 50-456 for Unit 1 and STN 50-457 for Unit 2. After satisfactory plant construction and preoperational testing was completed, Braidwood Station was granted a full power operating license for Unit 1, NPF-72, on July 2, 1987 and subsequently commenced commercial operation on July 29, 1988; the full power operating license for Unit 2, NPF-77, was granted on May 20, 1988 and commercial operation commenced on October 17, 1988.

Braidwood Station's piping systems and associated components were designed and fabricated to the examination requirements of ASME Section XI. Although this plant was specifically designed to meet the requirements of ASME Section XI, literal compliance may not be feasible or practical within the limits of the current plant design. Certain limitations are likely to occur due to conditions such as accessibility, geometric configuration, and/or metallurgical characteristics. For some inspection categories, an alternate component may be selected for examination and the code statistical and distribution requirements can still be maintained.

If Code required examination criteria cannot be met, a relief request will be submitted in accordance with 10 CFR 50.55a.

1.3 First Interval lSI Program Pursuant to the Code Of Federal Regulations (CFR), Title 10, Part 50, Section 55a, Codes and standards, (10 CFR 50.55a), Braidwood Station was required to meet the requirements of Paragraph (g), Inservice inspection requirements, of that section.

Specifically, Paragraph 10 CFR 50.55a(g)(4)(i) called for the Inservice Inspection requirements of the 120 month inspection interval to comply with the requirements of the latest Edition and Addenda of ASME Section XI referenced in Paragraph (b) of 10 CFR 50.55a on the date 12 months prior the date of issuance of the operating license, subject to the limitations and modifications listed in 10 CFR 50.55a(b).

The version of 10 CFR 50.55a in effect 12 months prior to the issuance of the Braidwood Station Unit 1 and Unit 2 operating license referenced ASME Section XI, 1983 Edition with Addenda through the Summer 1983 Addenda (83/S83) of the ASME Boiler and Pressure Vessel (B&PV)

Code, ASME Section XI, titled Rules for Inservice Inspection of Nuclear Power Plant Components in Paragraph (b)(2). The inservice inspection 1-6 151 Program Plan Revision 0

151 Program Plan Braidwood Station Units 1 & 2, Third Interval requirements applicable to nondestructive examination and system pressure testing for the First lSI Program were based on these rules. The extent of the application of ASME Section XI 83/S83 was limited by Paragraph (2)(iv)(A) such that ASME Section XI, 1974 Edition with Addenda through Summer 1975 Addenda (74/S75) must be utilized for ASME Code Class 2 pressure retaining welds in Residual Heat Removal Systems, Emergency Core Cooling Systems, and Containment Heat Removal Systems. Optionally, per Paragraph (2)(iv)(B), plants with Construction Permits docketed prior to July 1, 1978, such as Braidwood Station, could use ASME Section XI 74/S75 to examine ASME Code Class 2 pressure retaining welds in systems other than those in Paragraph (2)(iv)(A). Based on these 10 CFR 50.55a mandatory and optional requirements, the Braidwood Station ASME Section XI lSI Program Plan for the initial ten year interval was developed by Braidwood Station.

The Braidwood Station first lSI interval started on July 29, 1988 and ended on July 28, 1998 for Unit 1, and started on October 17, 1988 and ended on October 16, 1998 for Unit 2.

1.4 Second Interval lSI Program Pursuant to 10 CFR 50.55a(g), Exelon was required to update the lSI Program at the end of the first lSI interval. The lSI Program was required to comply with the latest Edition and Addenda of the ASME Section XI incorporated by reference in 10 CFR 50.55a twelve months prior to the start of the interval per 10 CFR 50.55a(g)(4)(ii).

The second interval lSI Program Plan was developed in accordance with the requirements of 10 CFR 50.55a and the 1989 Edition, No Addenda of ASME Section XI. Where portions of other Codes were implemented, as allowed by 10 CFR 50.55a, those specific Codes were applied. The lSI Program Plan addressed Subsections IWA, IWB, IWC, IWD, and IWF of ASME Section XI, and complied with the requirements of Inspection Program B as defined therein.

The Braidwood Station Unit 1 second lSI interval started on July 29, 1998 and was scheduled to end on July 28,2008. The Braidwood Station Unit 2 second lSI interval was effective from October 17, 1998 through October 28, 2008 in accordance with the original pattern of intervals. As allowed by IWA-2430(d)(1), Braidwood Station Unit 1 took a 1 year extension for the Second lSI Interval until July 28, 2009. This extension will not affect the start of the Third lSI Interval for Unit 1. Braidwood Station Unit 1 extended the Second lSI Interval in order to complete the Second lSI Interval examinations (Examination Category B-P). Third lSI Interval examinations may also be performed during this time period, but in no case will a single examination be credited for both intervals.

1*7 151 Program Plan Revision 0

151 Program Plan Braidwood Station Units 1 & 2, Third Interval The Braidwood Station Second lSI Interval was effective from July 29, 1998 through July 28, 2009 for Unit 1, and from October 17, 1998 through October 16, 2008 for Unit 2.

1.5 Third Interval lSI Program Pursuant to 10 CFR 50.55a(g), licensees are required to update their lSI Programs to meet the requirements of ASME Section XI once every ten years or inspection interval. The lSI Program is required to comply with the latest Edition and Addenda of the ASME Section XI incorporated by reference in 10 CFR 50.55a twelve months prior to the start of the interval per 10 CFR 50.55a(g)(4)(ii). The start of the Braidwood Station third lSI interval will be on July 29, 2008 for Unit 1, and October 17, 2008 for Unit 2 in accordance with the original pattern of intervals. Based on this date, the latest Edition and Addenda of the ASME Section XI referenced in 10 CFR 50.55a(b)(2) twelve months prior was the 2001 Edition through the 2003 Addenda.

The Braidwood Station third interval lSI Program Plan was developed in accordance with the requirements of 10 CFR 50.55a and the 2001 Edition through the 2003 Addenda of ASME Section XI, subject to the limitations and modifications contained within Paragraph (b) of the regulation. These limitations and modifications are detailed in Table 1.8-1 of this section.

This lSI Program Plan addresses Subsections IWA, IWB, IWC, IWD, IWF, Mandatory Appendices, approved ASME Code Cases, approved alternatives through relief requests and Safety Evaluation Reports (SER's), and utilizes Inspection Program B as defined therein.

Braidwood Station adopted the EPRI Topical Report TR-112657, Rev. B-A methodology, which is supplemented by Code Case N-578-1, for implementing risk-informed inservice inspections. The RISI Program will be in effect for the entire Third lSI Interval. This approach replaces the categorization, selection, and examination volume requirements for portions of ASME Section XI Examination Categories B-F, B-J, C-F-1, and C-F-2 applicable to Braidwood Station with Examination Category R-A as defined in Code Case N-578-1. Implementation of the RISI Program is in accordance with Relief Request 13R-01.

Braidwood Station has also adopted the EPRI Topical Report TR-1006937, Rev. O-A, methodology for additional guidance for adaptation of the RISI evaluation process to Break Exclusion Region (BER) piping, also referred to as the High Energy Line Break (HELB) region. This change to the BER program was made under 10 CFR 50.59 evaluation criteria. The RISI evaluation for BER piping remains in effect for the third lSI interval.

1-8 151 Program Plan Revision 0

151 Program Plan Braidwood Station Units 1 & 2, Third Interval 1.6 First Interval CISI Program CISI examinations were originally invoked by amended regulations contained within a Final Rule issued by the Nuclear Regulatory Commission (NRC). The amended regulation incorporated the requirements of the 1992 Edition through the 1992 Addenda of the ASME Section XI, Subsections IWE and IWL, subject to specific modifications that were included in Paragraphs 10 CFR 50.55a(b)(2)(ix) and 10 CFR 50.55a(b)(2)(x).

The final rulemaking was published in the Federal Register on August 8, 1996 and specified an effective date of September 9, 1996.

Implementation of the Subsection IWE and IWL Program from a scheduling standpoint was driven by the five year expedited implementation period per 10 CFR 50.55a(g)(6)(ii)(B), which specified that the examinations required to be completed by the end of the first period of the first CISI interval (per Table IWE-2412-1) be completed by the effective date (by September 9, 2001).

ASME Section XI Subsections IWE, IWL, Mandatory Appendices, approved ASME Code Cases, and approved alternatives through relief requests and SER's were developed to implement these requirements.

The first CISI interval was effective from July 29, 1998 through July 28, 2008 for Braidwood Station Unit 1, and from October 17, 1998 through October 16, 2008 for Braidwood Station Unit 2. The CISI Program Plan was developed and implemented prior to the required date, and examinations were performed in accordance with the first CISI Interval schedule.

1.7 Second Interval CISI Program Pursuant to 10 CFR 50.55a(g), licensees are required to update their CISI Programs to meet the requirements of ASME Section XI once every ten years or inspection interval. The CISI Program is required to comply with the latest Edition and Addenda of the ASME Section XI incorporated by reference in 10 CFR 50.55a twelve months prior to the start of the interval per 10 CFR 50.55a(g)(4)(ii). The start of the second CISI interval is July 29,2008 for Braidwood Station Unit 1, and October 17, 2008 for Braidwood Station Unit 2. Based on this date, the latest Edition and Addenda of ASME Section XI referenced in 10 CFR 50.55a(b)(2) twelve months prior was the 2001 Edition through the 2003 Addenda.

The Braidwood Station Second CISI Interval will be effective from July 29, 2008 through July 28, 2018 for Unit 1, and from October 17, 2008 through October 16, 2018 for Unit 2 in accordance with the original pattern of intervals.

151 Program Plan Braidwood Station Units 1 & 2, Third Interval 2.0 BASIS FOR INSERVICE INSPECTION PROGRAM 2.1 ASME Section XI Examination Requirements As required by 10 CFR 50.55a, the lSI and CISI Programs were developed in accordance with the requirements detailed in the 2001 Edition through the 2003 Addenda, of the ASME Boiler and Pressure Vessel Code,Section XI, Division 1, Subsections IWA, IWB, IWC, IWD, IWE, IWF, IWL, Mandatory Appendices, Inspection Program B of IWA-2432, approved ASME Code Cases, and approved alternatives through relief requests and Safety Evaluation Reports (SER's).

The lSI Program implements Appendix VIII, "Performance Demonstration for Ultrasonic Examination Systems," ASME Section XI 2001 Edition, No Addenda as required by 10 CFR 50.55a(b)(2)(xxiv). Appendix VIII requires qualification of the procedures, personnel, and equipment used to detect and size flaws in piping, bolting, and the reactor pressure vessel (RPV). Each organization (e.g., owner or vendor) will be required to have a written program to ensure compliance with the requirements. These requirements were initially implemented through the Performance Demonstration Initiative (PDl) Program according to the schedule defined in 10 CFR 50.55a(g)(6)(ii)(C).

For the third lSI interval, Braidwood Station's inspection program for ASME Section XI Examination Categories B-F, B-J, C-F-1, and C-F-2 will be governed by risk-informed regulations. The RISI program methodology is described in the EPRI Topical Report TR-112657, Rev. B-A. To supplement the EPRI Topical Report, Code Case N-578-1 (as applicable per Relief Request 13R-01) is also being used for the classification of piping structural elements under the RISI program. The RISI program scope has been implemented as an alternative to the 2001 Edition through the 2003 Addenda, ASME Section XI examination program for Class 1 B-F and B-J welds and Class 2 C-F-1 and C-F-2 welds in accordance with 10 CFR 50.55a(a)(3)(i). The basis for the resulting Risk Categorizations of the nonexempt Class 1 and 2 piping systems at Braidwood Station is defined and maintained in the Final Report "Risk Informed Inservice Inspection Evaluation" as referenced in Section 9.0 of this document.

For the third lSI interval, the RISI program scope will continue to include welds in the BER piping, also referred to as the HELB region, which includes several non-class welds that fall within the BER augmented inspection program. The BER program methodology is described in EPRI Topical Report TA-1006937, Aev. O-A, which has been used to define the inspection scope in lieu of the 100% volumetric examination of all piping welds in the previous BEA augmented inspection program. Therefore, all welds in the original augmented inspection program for BEA remain evaluated under the AISI Program using an integrated risk-informed approach.

2.1.3 O&M Code Cases As referenced by 10 CFR 50.55a(b)(6) and allowed by NRC Regulatory Guide 1.192, Revision 0, the following Code Cases are being incorporated into the Braidwood Station lSI Program.

OMN-13, Rev. 0 Requirements for Extending Snubber Inservice Visual Examination Interval at LWR Power Plants 2.2 Augmented Examination Requirements Augmented examination requirements are those examinations that are performed above and beyond the requirements of ASME Section XI.

Below is a summary of those examinations performed by Braidwood 2-7 Program Plan Revision 0

lSI Program Plan Braidwood Station Units 1 & 2, Third Interval Station that are not specifically addressed by ASME Section XI, or the examinations that will be performed in addition to the requirements of ASME Section XI on a routine basis during the Third Inspection Interval.

2.2.1 NRC Branch Technical Position MEB 3-1, "High Energy Fluid Systems, Protection Against Postulated Piping Failures in Fluid Systems Outside Containment", dated November 24, 1975.

UFSAR Sections 3.6.1 and 3.6.2 detail Braidwood Station compliance with NRC Branch Technical Position MEB 3-1, which includes requirements for licensees to perform a 100% volumetric examination each interval of circumferential and longitudinal pipe welds within the pipe break exclusion regions associated with high energy piping in containment penetration areas.

Implementation of the examination commitments is included in Section 7.0 of this lSI Program Plan and the associated lSI Database.

Note: This commitment was previously maintained in accordance with UFSAR Section 3.6.1 and 3.6.2. With the implementation of the RISI-BER Program, all BER augmented welds were evaluated under the RISI methodology and were integrated into the RISI Program. The RISI Program will also include several non-class welds that fall within the BER augmented inspection program.

Additional guidance for adaptation of the RISI evaluation process to BER piping is given in EPRI TR-1006937 Rev. O-A.

2.2.2 NRC Regulatory Guide 1.14, Reactor Coolant Pump Flywheel Integrity as modified by the requirements of Braidwood Station License Amendment #118 and Technical Requirements Manual Appendix G.

The commitment to Regulatory Guide 1.14 has been modified by Braidwood Station License Amendment #118. In lieu of Regulatory Position cA.b.(1) and cA.b.(2), a qualified in-place UT examination over the volume from the inner bore of the flywheel to the circle of one-half the outer radius or a surface examination (MT and/or PT) of exposed surfaces of the removed flywheel may be conducted at approximately 10 year intervals coinciding with the Inservice Inspection schedule as required by ASME Section XI.

2.2.3 NRC Bulletin 88-08, "Thermal Stresses in Piping Connected to Reactor Coolant Systems," including supplements 1,2, and 3.

This details Braidwood Station's commitment to examine welds susceptible to thermal stratification.

2-8 lSI Program Plan Revision 0

151 Program Plan Braidwood Station Units 1 & 2, Third Interval To address NRC Bulletin 88-08, Braidwood Station had committed to inspecting critical locations on the suction lines to the Residual Heat Removal (RHR) pumps from RCS loops 1 and 3, and the Auxiliary and Main Pressurizer Spray lines every other refueling outage.

With the implementation of the RISI Program, the NRC Bulletin 88-08 augmented inspection commitment will no longer be required at Braidwood Station. The RISI Program completely subsumed this requirement based on the fact that the Degradation Mechanism assessment and Risk Categorization involve full assessment for Thermal Transients and Thermal Stratification, Cycling, and Striping. Thus, these piping structural elements have been categorized and selected for examination in accordance with the EPRI Topical Reports TR-112657, Rev. B-A, TR-1006937, Rev.

O-A, and Code Case N-578-1 in lieu of the original commitment to NRC Bulletin 88-08.

2.2.4 Augmented volumetric examinations of Class 2 ECC, RHR, and CHR (Containment Spray, Chemical and Volume Control, Residual Heat Removal, and Safety Injection) system piping.

Braidwood Station has committed to volumetrically examine 7.5%

of the circumferential piping welds, greater than 4 inch nominal pipe size, within systems which contain stagnant borated water and are not subject to volumetric examination per ASME Section XI.

Note: Commitment to be maintained after the implementation of Risk-Informed lSI as this evaluation did not address the Class 2 components with wall thickness < 0.375".

2.2.5 Code Case N-729-1, "Alternative Examination Requirements for PWR Reactor Vessel Upper Heads With Nozzles Having Pressure-Retaining Partial-Penetration Welds". All licensees of pressurized water reactors are required to augment their inservice inspection program with ASME Code Case N-729-1 subject to the conditions specified in paragraphs 10 CFR 50.55a(g)(6)(ii)(D)(2) through (6).

This requirement replaces previous inspections that were mandated under NRC First Revised Order EA-03-009, "ISSUANCE OF FIRST REVISED NRC ORDER (EA-03-009) ESTABLISHING INTERIM INSPECTION REQUIREMENTS FOR REACTOR PRESSURE VESSEL HEADS AT PRESSURIZED WATER REACTORS" dated February 20, 2004.

2.2.6 MRP-139 "Primary System Piping Butt Weld Inspection and Evaluation Guideline" provides a strategy to manage degradation of butt welds in primary system piping that are 1" NPS or greater 2-9 151 Program Plan Revision 0

lSI Program Plan Braidwood Station Units 1 & 2, Third Interval and are exposed to temperatures greater than or equal to cold leg temperature.

Braidwood Station has committed to comply with the criteria of MRP-139 for welds that are potentially susceptible to Primary Water Stress Corrosion Cracking (PWSCC). This commitment affects 28 welds (14 welds per unit) where dissimilar metal welds are used to join piping nozzles on the RPV or Pressurizer. The MRP-139 requirements are independent from the RISI Program, and these examinations will be performed in addition to the RISI Program examinations, unless dual crediting can occur for single examinations that meet the individual requirements of both the RISI Program and MRP-139.

2.2.7 NRC NUREG-0737, Section 111.0.1.1, dated November 1980.

Requires applicants to implement a program to reduce leakage from systems outside containment that would or could contain highly radioactive fluids or gases during a serious transient or accident to as low as practical levels. In response to this NUREG commitment, Section E.77, Primary Coolant Sources Outside Containment, was included in the Byron/Braidwood UFSAR. This UFSAR Section along with Technical Specifications Section 5.5.2 require performance of integrated leak tests at refueling cycle intervals or less on each system or portions of systems, which could potentially contain highly radioactive liquids or gases.

Implementation of the Braidwood Station program addressing these requirements is included in BwVS 290-1, BwVS 290-2-GW, and BwVS 290-2-0G.

2.2.8 Generic Letter 88-05, "Boric Acid Corrosion of Carbon Steel Reactor Pressure Boundary Components in PWR Plants".

The NRC issued Generic Letter (GL) 88-05 to all licensees of operating Pressurized Water Reactors (PWR) in March, 1988.

This Generic Letter deals with boric acid corrosion of carbon steel reactor coolant pressure boundary components in PWR plants.

Specifically, GL 88-05 requested information to assess safe operation of PWR's when reactor coolant leaks below Tech Spec limits develop and the coolant containing Boric Acid comes in contact with and degrades low alloy carbon steel components.

Braidwood's response to GL 88-05 requirements are incorporated through the completion of normal station operator walkdowns, heightened Maintenance and Tech Staff (now Plant Engineering) training, the normal lnservice Inspection Program, and the ASME Section Xl System Pressure Testing Program.

2-10 lSI Program Plan Revision 0

151 Program Plan Braidwood Station Units 1 & 2, Third Interval To ensure compliance with this augmented commitment, the Reactor Coolant Pressure Boundary (RCPB), as defined by UFSAR Section 5.2, shall have a system inspection performed by certified VT-2 visual examiners every refueling outage consisting of a pre-outage visual examination as well as a visual examination conducted prior to startup. These examinations shall be conducted to identify evidence of boric acid crystallization and residue accumulations.

2.2.9 Code Case N-722, "Additional Examinations for PWR Pressure Retaining Welds in Class 1 Components Fabricated with Alloy 600/82/182 Materials". All licensees of pressurized water reactors shall augment their inservice inspection program by implementing ASME Code Case N-722 subject to the conditions specified in paragraphs 10 CFR 50.55a(g)(6)(ii)(E)(2) through (4). The inspection requirements of ASME Code Case N-722 do not apply to components with pressure retaining welds fabricated with Alloy 600/82/182 materials that have been mitigated by weld overlay or stress improvement.

2.3 System Classification and P&ID Boundary Drawings The lSI Classification Basis Document details those systems that are lSI Class 1, 2, 3, or MC that fall within the lSI scope of examinations. The concrete containment structure and post-tensioning system is CISI Class CC and is shown on the containment roll-out drawings. Below is a summary of the classification criteria used within the lSI Classification Basis Document.

Each safety related fluid system containing water, steam, air, oil, etc.

included in the Braidwood Station UFSAR was reviewed to determine which safety functions they perform during all modes of system and plant operation. Based on these safety functions, the systems and components were evaluated per classification documents. The systems were then designated as lSI Class 1, 2, 3, MC, or non-classed accordingly. This evaluation followed the guidelines of UFSAR Section 5.2.4 for lSI Class 1 and 6.6 for lSI Classes 2 and 3. Safety related portions of systems are defined on the Piping and Instrument Diagrams (P&ID's) and Control and Instrumentation Diagrams (C&ID's).

When a particular group of components is identified as performing a lSI Class 1, 2, or 3 safety function, the components are further reviewed to assure the interfaces (boundary valves and boundary barriers) meet the criteria set by 10 CFR 50.2, 10 CFR 50.55a(c)(1), 10 CFR 50.55a(c)(2),

Regulatory Guide 1.26, and ANSI N18.2-1973. Although Braidwood Station is not committed to or licensed in accordance with these documents, Standard Review Plan (SRP) 3.2.2 "System Quality Group Classification," and other American National Standards Institute/American 2*11 151 Program Plan Revision 0

lSI Program Plan Braidwood Station Units 1 & 2, Third Interval Nuclear Society (ANSI/ANS) standards were also used for gUidance in determining the classification boundaries when 10 CFR and Regulatory Guide 1.26 did not address a given situation. The valve positions shown on the system flow diagrams are assumed to be the normal positions during system operation unless otherwise noted.

lSI classification boundaries are defined by the Inservice Inspection lSI Code Boundary Drawings (lSI CBD's) with classification line codes. A summary of the line coding system used on the lSI CBD's to identify safety related systems or portions of systems subject to examination is included on drawing ISI-CBD-LEGEND. Typically, unhatched, solid coding (blue, yellow and green, Coding Designators 1A, 2A, and 3A, respectively) was used for nonexempt ASME Section XI components.

Some hatched codings, (Coding Designators 2HPSI, 2F, and 3C) were also used to identify nonexempt ASME Section XI components. The remaining codings shown on ISI-CBD-LEGEND (Coding Designators 1B, 1C, 10, 28, 2C, 20, 2E, 3B, and 3D) were used to identify exempt ASME Section XI components. In addition to the line coding system shown on ISI-CBD-LEGEND, codings used to develop Braidwood Station Units 1 and 2 System Pressure Testing Program are shown on drawing SPT-TBD-LEGEND, Sheet 1.

The systems and components (piping, pumps, valves, vessels, etc.),

which are subject to the examinations of Articles IWB-2000, IWC-2000, IWD-2000, IWF-2000, and pressure tests of IWB-SOOO, IWC-SOOO, and IWD-SOOO are identified on the lSI CBD's as detailed in Tables 2.3-1 and 2.3-2. Containment components subject to examination of Articles IWE-2000 and IWL-2000 are identified on the CISI Component Drawings shown in Tables 2.4-3 and 2.4-4.

C-H,D-B C7.10, 02.10 System Leakage Testing of Non-Isolable Buried Components.

Non-Isolable Buried Pressure Retaining Components IWA 5244(b)(2) requires non-isolable buried components be tested to confirm that flow during operation is not impaired.

POSITION:

Article IWA-5000 provides no guidance in setting acceptance criteria for what can be considered "adequate flow". In lieu of any formal guidance provided by the Code, Braidwood Station has established the following acceptance criteria:

For opened ended lines on systems that require Inservice Testing (1ST) of pumps, adherence to 1ST acceptance criteria is considered as reasonable proof of adequate flow through the lines.

For lines in which the open end is accessible to visual examination while the system is in operation, visual evidence of flow discharging the line is considered as reasonable proof of adequate flow through the open ended line.

For open ended portions of systems where the process fluid is pneumatic, evidence of gaseous discharge shall be considered reasonable proof of adequate flow through the open ended line. Such test may include passing smoke through the line, hanging balloons or streamers, using a remotely operated blimp, using thermography to detect hot air, etc.

This acceptance criteria will be utilized in order to meet the requirements of IWA-5244(b)(2).

Braidwood Station's position is that proof of adequate flow is all that is required for testing these open ended lines and that no further visual examination is necessary. This is consistent with the requirements for buried piping, which is not subject to visual examination.

1,2, and 3 lWA-5221 IWA-5222 B-P C-H D-B B15.10, C7.10, 02.10 Valve Seats as Pressurization Boundaries.

All Pressure Testing Boundary Valves IWA-5221 requires the pressurization boundary for system leakage testing extend to those pressure retaining components under operating pressures during normal system service.

POSITION:

Braidwood Station's position is that the pressurization boundary extends up to the valve seat of the valve utilized for isolation. For example, in order to pressure test the Class 1 components, the valve that provides the Class break would be utilized as the isolation point. In this case the true pressurization boundary, and Class break, is actually at the valve seat.

Any requirement to test beyond the valve seat is dependent only on whether or not the piping on the other side of the valve seat is lSI Class 1, 2, or 3.

In order to simplify examination of classed components, Braidwood Station will perform a VT-2 visual examination of the entire boundary valve body and bonnet (during pressurization up to the valve seat).

B-A, Revised Risk-Informed Inservice Inspection Evaluation Procedure Previously B-F, B-J, C-F-1, and C-F-2 now incorporated into R-A RISI examination volumes and methods The requirements for examination methods and areas/volumes are assembled from several sources other than the station's base edition of the ASME Code.

Relief Request 13R-01 :

For this application, the guidance for the examination volume for a given degradation mechanism is provided by the EPRI Topical Report while the guidance for the examination method is provided by Code Case N-578-1.

Executive Summary, Section 3.5 Inspection Location Selection and NDE Selection:

Code Case N-578-1 Table 1, "Examination Category R-A, "Risk-Informed Piping Examinations" will also be used in conjunction with Table 4-1 of EPRI TR-112657 to categorize the parts examined under the RISI Program. Code Case N-578-1 Table 1 provides examination requirements, examination method, acceptance standards, examination extent and frequency for piping structural elements not subject to a damage mechanism.

Code Case N-578-1, Section 1-5.2 Examination Volumes and Methods:

Examination programs developed in accordance with this Case shall use NDE techniques suitable for specific degradation mechanisms and examination locations.

The examination volumes and methods that are appropriate for each degradation mechanism are provided in Table 1 of this Case. The methods and procedures used 2-40 151 Program Plan Revision 0

TR-112657, Section 4 Mechanism Specific Examination Volumes and Methods:

Application of RISI uses NDE techniques that are designed to be effective for specific degradation mechanisms and examination locations. This inspection for cause approach involves identification of specific damage mechanisms that are likely to be operative, the location where they may be operative, and the appropriate examination methods and volumes specific to address the damage mechanism.

Note 1:

VT-2 examinations are performed during each refueling cycle. VT-2 examination area is not identified in Code Case N-578-1 or TR-112657. Socket welds are not specifically addressed in TR-112657 with the exception of FAC exams. N-578-1 Table 1 Note 12 specifies that socket welds require only a VT-2 exam.

Note 2:

N-578-1 requires a VT-2 examination for this OM while TR-112657 requires a volumetric or visual method. Recent industry events necessitated the change to volumetric examination techniques (where qualified examination techniques are available) for detection prior to through-wall leakage. TR-112657 identifies Figures 4-8 and 4-9 for the required examination volumes based on component configuration.

Figure 4-8 would not be applicable to components incorporated into RISI. At Braidwood Station, all components subject to PWSCC (14 in each unit) are classified as High-Risk Group, Risk Category 2.

3.2 Risk-Informed Examination Requirements Piping structural elements that fall under RISI Examination Category R-A are non-exempt Class 1 and 2 piping components as described in Section 3.1 above, and are risk ranked as High (1, 2, and 3), Medium (4 and 5), or Low (6 and 7). Per the EPRI Topical Reports TR-112657, Rev. B-A, TR-1006937, Rev. O-A, and Code Case N-578-1, piping structural elements ranked as High or Medium Risk are subject to examination while piping structural elements ranked as Low Risk are not subject to examinations (except for pressure testing).

Piping structural elements may be excluded from examination (other than pressure testing) under the RISI Program if the only degradation mechanism present for a given location is inspected for under certain other station programs such as the Flow Accelerated Corrosion (FAC) or Microbiologically Induced Corrosion (MIC) Programs. These piping structural elements will remain part of the FAC or Service Water programs, which already perform "for cause" inspections to detect these degradation mechanisms. Piping structural elements susceptible to FAC or MIC and pitting along with another degradation mechanism (e.g.,

thermal fatigue) are retained as part of the RISI scope and are included in the element selection for the purpose of performing exams to detect the additional degradation mechanism. The RISI Program piping structural element examinations are performed in accordance with Relief Request 13R-01.

4-1 151 Program Plan Revision 0

151 Program Plan Braidwood Station Units 1 & 2, Third Interval The ASME Section XI lSI Program uses Subsection IWF to define support inspection requirements. The lSI Program maintains the Code Class snubbers in the populations subject to inspection per Subsection IWF. This is done to accommodate scheduling and inspection requirements of the related attachment hardware per Paragraphs IWF-5200(c) and IWF-5300(c). (See Section 4.2.2 below.)

4.2.2 ASME Section XI Paragraphs IWF-5200(c) and IWF-5300(c) require integral and nonintegral attachments for snubbers to be examined in accordance with Subsection IWF of the ASME Section XI. This results in VT-3 visual examination of the snubber attachment hardware including the bolting, pins, and their interface to the clamp, but does not include the component-to-clamp interface.

The ASME Section XI lSI Program uses Subsection IWF to define the inspection requirements for all Class 1, Class 2, and Class 3 supports, regardless of type. The lSI Program maintains the Code Class snubbers in the support populations subject to inspection per Subsection IWF. This is done to facilitate scheduling and inspection requirements of the snubber attachment hardware (e.g.,

bolting and pins) per Paragraphs IWF-5200(c) and IWF-5300(c).

It should be noted that the examination of snubber welded attachments will be performed in accordance with the ASME Section XI Subsections IWB, IWC, and IWD welded attachment examination requirements (e.g.; Examination Categories B-K, C-C, and D-A).

TABLE PROGRAM NOTES Note #

Note Summary 1

lSI snubber visual examinations and functional testing are performed in accordance with the ASME O&M Code, Subsection ISTD Program. The number of Braidwood Station Unit 1, 2, and Common supports identified include snubbers for the visual examination and functional testing of the integral and nonintegral attachments per Paragraphs IWF-52oo(c), IWF-5300(c), and IWF-2500(a). The snubbers are scheduled and administratively tracked in the lSI Program; however, the ASME O&M Code, Subsection ISTD Program will be the mechanism for actually performing the visual examinations and functional testing scheduled within the lSI program. For a detailed discussion of the snubber program, see Section 4.2.

2 The Braidwood 8lQUV, Unit 1 population counts include those components that are common to both units (typically designated as "Common" or "Unit 0")

3 Valve bolting is characterized by one entry per valve, pump, piping flanges, or vessel manways, not by the actual total number of bolts or studs.

When the examination is required for a given item's bolting, all bolts shall be inspected. The reactor vessel closure head studs, nuts, and washers [54 (Unit 1) and 53 (Unit 2) total for each item] are examined during more than one Inspection Period. The number of separate examinations for each item identifies the population of these components.

4 With the implementation of the RISI Program, the NRC Bulletin 88-08 augmented inspection commitment will no longer be required at Braidwood Station. The RISI Program completely subsumed this requirement based on the fact that the Degradation Mechanism assessment and Risk Categorization involved full assessment for Thermal Transients and Thermal Stratification, Cycling, and Striping. Thus, these piping structural elements have been categorized and selected for examination in accordance with the EPRI Topical Repol1 TR-112657, Rev. B-A and Code Case N-578-1 in lieu of the original commitment to NRC Bulletin 88-08.

5 The population counts reported represents the number of nonexempt circumferential welds (piping structural elements). Longitudinal welds are also subject to examination, but actual counts are not reported here. Braidwood Station examines the portion of the longitudinal weld that falls within the intersecting circumferential weld examination volume.

--.-,-----~"--,-~~--

6 Subsection IWC, Table IWC-2500-1, Examination Category C-B, Item Number C2.22 requires volumetric examination of the nozzle inner radii of nozzles without reinforcing plates in vessels with nominal thickness> 1/2 inches. The main steam nozzle was designed with an internal multiple venturi type flow restrictor with an equivalent throat diameter of 16 inches. This design is used to limit the flow in the event of a postulated steam line break. This design does not utilize a radius nozzle as described in Figures IWC-2500-4(a) and (b), and therefore is not considered as an Examination Category C-B, Item Number C2.22 component. However, these nozzles will receive a system leakage test during each inspection period to verify structural integrity.

-~--------~--

7 For the Third Inspection Interval, Braidwood Station's Class 1 and 2 piping inspection program will be governed by risk-informed regulations. The RISI Program methodology is described in the EPRI Topical Reports TR-112657, Rev. B-A, TR-1006937, Rev. O-A, and Code Case N-578-1. The RISI Program scope has been implemented as an alternative to the 2001 Edition through the 2003 Addenda of the ASME Section XI examination program for Class 1 B-F and B-J welds and Class 2 C-F-1 and C-F-2 welds in accordance with 10 CFR 50.55a(a)(3)(i).


_.~-

8 Examination methods for Class 1 and 2 piping structural elements within the RISI Program are determined by the various degradation mechanisms present at each individual piping structural element. See EPRI Topical Reports TR-112657, Rev. B-A, TR-1006937, Rev. O-A, and Code Case N-578-1 for specific exam method requirements.

9 For the Third Inspection Interval, the RISI Program scope has been expanded to include welds in the BER piping, also referred to as the HELB region, which includes several non-class welds that fall within the BER augmented inspection program. All BER augmented welds have been evaluated under the RISI methodology and have been integrated into the RISI Program under the 10 CFR 50.59 change process. Additional guidance for adaptation of the RISI evaluation process to BER piping is given in EPRI TR-1006937 Rev. O-A. Thus, these welds have been categorized and selected for examination in accordance with the EPRI Topical Reports TR-112657, Rev. B-A, TR-1006937, Rev. O-A, and Code Case N-578-1 in lieu of the VII~IIIQI commitment to I\\JUREG 0800 in UFSAR Section 3.6.2.

10 Containment bolted connections that are disassembled during the scheduled performance of the examinations in Item Number E1.11 must be examined using the VT-3 method. Flaws or degradation identified during the VT-3 examination must be examined in accordance with the VT-1 examination method, using the criteria in the material specification or IWB-3517.1 to evaluate bolting flaws or degradation. In lieu of performing the required VT-3 during scheduled E1.11 examinations the VT-3 of containment bolted connections may be performed whenever containment bolted connections are disassembled for any reason. These modifications are required by 10 CFR 50.55a(b)(2)(ix)(G) and 10CFRc;n

, Examination Category C-H, requires the system parts to be VT-2 visually examined be those other than open ended portions of systems. Interpretation XI-1-89-30 supports the approach of excluding open ended portions of Class 2 systems from normal periodic VT-2 visual examination.

The definition of "open ended" in ASME Section XI, Subsection IWA-9000 is a condition of piping which permits free discharge. Therefore, open ended piping up to the first isolation valve on Class 2 systems is excluded from the system pressure testing program per Footnote 1 as discussed above. Since check valves in discharge lines still permit free discharge flow, these valves do not qualify as an isolation valve for the purpose of applying Footnote 1 of Table IWC-2500-1, Examination Category C-H. The excluded Class 2 piping thus extends up to the next isolation point in discharge lines when the last valve in the piping is a check valve (Reference the Containment Spray discharge piping and ring headers for an example of this configuration).

SUMMARY

TABLE PROGRAM NOTES Note Summary Generic Letter 88-05 dated March 17, 1988 addresses boric acid corrosion of carbon steel reactor pressure boundary components in pressurized water reactors. Per the Braidwood Station response to Generic Letter 88-05, Commonwealth Edison letter from W. Morgan to B.

Davis dated May 31,1988 (NTS Item #456-104-88-00500), a pre-outage VT-2 visual examination shall be performed to locate evidence of boric acid leakage from the reactor coolant pressure boundary. ASME Section XI also requires a VT-2 visual examination of all Class 1 components prior to reactor start-up. For those portions of the reactor coolant pressure boundary that are ASME Class 2 as defined by UFSAR Section 5.2, a post-outage VT-2 visual examination shall also be performed to locate evidence of boric acid leakage.

Leakage from systems containing boric acid results in residue and crystallization accumulations. By performing a VT-2 visual inspection prior to entering an outage (a station augmented inspection commitment as outlined above), any evidence of boric acid accumulations will be found and investigated to determine the source of leakage before normal outage maintenance activities can clean off the crystals and residue. These visual examinations are performed using certified VT-2 visual examiners in accordance with the Exelon VT-2 procedure. This procedure utilizes ASME Section XI VT-2 certified visual examiners and has proven successful in locating evidence of boric acid leakage in the past. Since this augmented inspection is performed solely for the purpose of detecting evidence of boric acid leakage, the system is not required to be pressurized provided any evidence of boric acid accumulations is evaluated and the source of the leakage is determined. This action may require pressurizing the system as part of the evaluation process.

Braidwood Station Unit 1 systems or portions of systems subject to the augmented testing of Generic Letter 88-05 are included on P&IDs M-60 Sheets 1A, 1B, 2, 3, 4, and 5; M-61 Sheets 2, 3, 4, 5, and 6; M-62; M-64 Sheets 1, 2, 3B, and 5; M-68 Sheets 1A, 1S, and 7; and M-2060 Sheets 6,7,8,17, and 18.

Note Summar I

23 Paragraph IWB-5221 (a) requires that for the 10-year interval system pressure test, the system shall be pressurized to a pressure not less than the pressure corresponding to 100% rated reactor power. Paragraph IWB-5222(b) requires that the boundary subject to test pressurization during this test shall extend to all Class 1 pressure retaining components within the system boundary.

Certain portions of the lSI Class 1 boundary are normally isolated during the periodic system leakage test. Per Paragraph IWB-5222(b), these portions of the system are required to be pressurized and inspected once per 10-year interval. Typically, these portions of the Class 1 boundary are emergency core cooling system (ECCS) injection lines which are isolated from the reactor coolant pressure boundary by two check valves or valves whose logic is linked together. During the Class 1 system leakage test, the inboard valve is closed and these segments of lines are not pressurized. Also, the ECCS systems are not typically tested during an injection to the reactor vessel but rather during a test mode line up, and thus the Class 1 isolated line segments are not pressurized during the ECCS system test either. The pressure retaining boundary during the system leakage test shall correspond to the reactor coolant system boundary, with all valves in the normal position, which is required for normal reactor operation startup. The VT-2 visual examination shall, however, extend to and include the second closed valve at the boundary extremity.

Through the use of jumper hoses, an external test rig, or an abnormal valve line-up, the isolated portions of the Class 1 boundary shall be pressurized once every 10-year inspection interval. The test pressure shall be the same test pressure as that of the Class 1 system leakage test per Paragraph IWB-5222(b). These portions of lines are Class 1 due to their reactor coolant isolation function. They are not made Class 1 due to the connected ECCS system safety function.

1----

24 They are also designed and installed to withstand the pressures associated with isolating the reactor coolant system. Taking into account the Class 1 boundary isolation function of these lines, the nominal operating pressure of these segments when performing their Class 1 safety function would be the normal reactor coolant pressure as required by the code case. Therefore, any special tests performed on these lines shall be performed at minimum pressure associated with normal reactor coolant pressure (approx. 2235 psig).

~

~~__".....__.._.__

Table IWC-2500-1, Examination Category C-H, requires a VT-2 visual examination of all components within the pressure retaining boundary be performed during a system leakage test each inspection period.

The Positive Displacement Charging Pump has been Out-of-Service since startup and no periodic tests are being performed on the pump.

Therefore, the discharge piping as bounded by the Positive Displacement pump, discharge check valve 1(2)CV8497, discharge bypass to Volume Control Tank isolation valve 1(2)CV81 09, and pressure relief valve 1(2)CV8118 is excluded from periodic system pressure testing.

However, if Braidwood Station places the Positive Displacement Charging Pump back into service at some future date, this discharge piping will be subject to normal periodic system pressure testing and VT-2 visual examination.

Ir---~~~

Augmented testing per NUREG-0737 are still required to be performed on the subject boundary.

, Apply requirements of Code Case N-729-1 as modified below:

Note 9 of ASME Code Case N-729-1 shall not be implemented.

Instead of the specified 'examination method' requirements for volumetric and surface examinations in Note 6 of Table 1 of Code Case N-729-1, the licensee shall perform volumetric and/or surface examination of essentially 100 percent of the required volume or equivalent surfaces of the nozzle tube, as identified by Figure 2 of ASME Code Case N-729-1. A demonstrated volumetric or surface leak path assessment through all J-groove welds shall be performed. If a surface examination is being substituted for a VOlumetric examination on a portion of a penetration nozzle that is below the toe of the J-groove weld [Point E on Figure 2 of ASME Code Case N-729-1], the surface examination shall be of the inside and outside wetted surface of the penetration nozzle not examined volumetrically.

By September 1, 2009, ultrasonic examinations shall be performed using personnel, procedures and equipment that have been qualified by blind demonstration on representative mockups using a methodology that meets the conditions specified in (10 CFR 50.55a(g)(6)(ii)(D)(3)(i) through 10 CFR 50.55a(g)(6)(ii)(D)(4)(iv), instead of the qualification requirements of Paragraph -2500 of ASME Code Case N-729-1. References herein to Section XI, Appendix VIII shall be to the 2004 Edition with no Addenda of the ASME BPV Code.

The specimen set shall have an applicable thickness qualification range of +25 percent to -40 percent for nominal depth through-wall thickness.

The specimen set shall include geometric and material conditions that normally require discrimination from primary water stress corrosion cracking (PWSCC) flaws.

The specimen set shall have a minimum of ten (10) flaws which provide an acoustic response similar to PWSCC indications. All flaws shall be greater than 10 percent of the nominal pipe wall thickness. A minimum of 20 percent of the total flaws shall initiate from the inside surface and 20 percent from the outside surface. At least 20 percent of the flaws shall be in the depth ranges of 10--30 percent through wall thickness and at least 20 percent within a depth range of 31-50 percent through wall thickness. At least 20 percent and no more than 40 percent of the flaws shall be oriented axially.

Procedures shall identify the equipment and essential variables and settings used for the qualification, and are consistent with Subarticle VIII-2100 of Section XI, Appendix VIII. The procedure shall be requalified when an essential variable is changed outside the demonstration range as defined by Subarticle VIII-3130 of Section XI, Appendix VIII and as allowed by Articles VI11-41 00, VIII-4200 and VIII-4300 of Section XI, Appendix VIII. Procedure qualification shall include the equivalent of at least three personnel performance demonstration test sets. Procedure qualification requires at least one successful personnel performance demonstration.

Personnel performance demonstration test acceptance criteria shall meet the personnel performance demonstration detection test acceptance criteria of Table VIII-S1O-1 of Section XI, Appendix VIII, Supplement 10. Examination procedures, equipment, and personnel are qualified for depth siZing and length sizing when the RMS error, as defined by Subarticle VIII-3120 of Section XI, Appendix VIII, of the flaw depth measurements, as compared to the true flaw depths, do not exceed 1/8 inch (3 mm), and the root mean square (RMS) error of the flaw length measurements, as compared to the true flaw lengths, do not exceed 3/8 inch (10 mm), respectively.

If flaws attributed to PWSCC have been identified, whether acceptable or not for continued service under Paragraphs -3130 or -3140 of ASME Code Case N-729-1, the re-inspection interval must be each refueling outage instead of the re-inspection intervals required by Table 1, Note (8) of ASME Code Case N-729-1.

All licensees of pressurized water reactors shall augment their inservice inspection program by implementing ASME Code Case N-722 subject to the conditions specified in paragraphs (g)(6)(ii)(E)(2) through (4) of 10 CFR 50.55a. The inspection requirements of ASME Code Case N-722 do not apply to components with pressure retaining welds fabricated with Alloy 600/82/182 materials that have been mitigated by weld overlay or stress improvement.

If a visual examination determines that leakage is occurring from a specific item listed in Table 1 of ASME Code Case N-722 that is not exempted by the ASME Code,Section XI, IWB-1220(b)(1), additional actions must be performed to characterize the location, orientation, and length of crack(s) in Alloy 600 nozzle wrought material and location, orientation, and length of crack(s) in Alloy 82/182 butt welds. Alternatively, licensees may replace the Alloy 600/82/182 materials in all the components under the item number of the leaking component.

If the actions in paragraph 10 CFR 50.55a(g)(6)(ii)(E)(2) determine that a flaw is circumferentially oriented and potentially a result of primary water stress corrosion cracking, licensees shall perform non-visual NDE inspections of components that fall under that ASME Code Case N-722 item number. The number of components inspected must equal or exceed the number of components found to be leaking under that item number. If circumferential cracking is identified in the sample, non-visual NDE must be performed in the remaining components under that item number.

If ultrasonic examinations of butt welds are used to meet the NDE requirements in paragraphs (g)(6)(ii)(E)(2) or (g)(6)(ii)(E)(3) of 10 CFR 50.55a, they must be performed usina the appropriate supplement of Section XI, Appendix VIII of the ASME Boiler and Pressure Vessel Code.

The following NRC guidance was utilized to determine the correct 10 CFR 50.55a paragraph citing for Braidwood Station relief requests.

10 CFR 50.55a(a)(3)(i) and 10 CFR 50.55a(a)(3)(ii) provide alternatives to the requirements of ASME Section XI, while 10 CFR 50.55a(g)(5)(iii) recognizes situational impracticalities.

10 CFR 50.55a(a)(3)(i):

Cited in relief requests when alternatives to the ASME Section XI requirements which provide an acceptable level of quality and safety are proposed. Examples are relief requests which propose alternative NDE methods and/or examination frequency.

10 CFR 50.55a(a)(3)(ii):

Cited in relief requests when compliance with the ASME Section XI requirements is deemed to be a hardship or unusual difficulty without a compensating increase in the level of quality and safety. Examples of hardship and/or unusual difficulty include, but are not limited to, excessive radiation exposure, disassembly of components solely to provide access for examinations, and development of sophisticated tooling that would result in only minimal increases in examination coverage.

10 CFR 50.55a(g)(5)(iii):

Cited in relief requests when conformance with ASME Section XI requirements is deemed impractical.

Examples of impractical requirements are situations where the component would have to be redesigned, or replaced to enable the required inspection to be performed.
