1.0 INTRODUCTION

AND BACKGROUND I . I Introduction This Inservice Inspection (ISi) Program Plan details the requirements for the examination and testing of ISi Class I, 2 , 3, MC, and CC pressure retaining components, supports, containment structures, metal liners, and post-tensioning systems at LaSalle County Station (LSCS ), Units I, 2, and Common (0). Unit Common components are included in the Unit I sections, reports, and tables. This ISi Program Plan also includes Containment Inservice Inspection (CISI), Risk-Informed Inservice Inspection (RI-ISi), Augmented Examinations (AUG), and System Pressure Testing (SPT) requirements imposed on or committed to by LSCS. This ISi Program Plan is controlled and revised in accordance with the requirements of procedure ER-AA-330, "Conduct of lnservice Inspection Activities," which implements the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (BPV) Code,Section XI ISi Program. The ISi Program Plan is credited for some LSCS License Renewal Aging Management Programs as listed in Section 2.2.8. At LSCS, the lnservice Testing (IST) Program is maintained and implemented separately from the ISi Program. The IST Basis Document and Program Plan contain all applicable inservicc testing requirements.

Likewise, the Snubber Program is maintained separately from the ISi Program and documents all of the applicahlc snubber visual examination, functional testing, and service life monitoring requirements.

The Fourth ISi Interval and the Third CISI Interval arc effective from October I, 2017 through September 30, 2027 for LSCS Units I and 2. Along with the update lo the ISi Program for the Fourth ISi Interval for ISi Class I, 2, and 3 components, including their supports, the CISI Program is also being updated for the Third CISI Interval for ISi Class MC and CC components.

This update will enable all of the ISi and CISI Program components I piping structural clements to he based on the same effective Edition and Addenda of ASME Section XI. as well as share a common interval start and end date. The common ASME Code of Record for the Fourth ISi Interval and the Third C'ISI Interval is the 2007 Edition with the 2008 Addenda. Paragraph IWA-2430(c)( I) of ASME Section XI allows an inspection interval to he extended or decreased hy as much as one year without restriction, and Paragraph IW A-2430(d) un interval to he extended when a unit is out of service for six months or more. The extension may he taken for a period of time not to exceed the duration of the outage.

I.I.<' l*I I ti ISi Program Plan LaSalle County Station Units I & 2, Fourth Interval The Fourth ISi Interval for ISi Class l, 2, and 3 components and the Third CISI Interval for ISI Class MC components and surfaces are divided into three inspection periods as determined by calendar years within the intervals.

Tables 1.1-1 and 1.1-2 identify the period start and end dates for the Fourth ISi Interval and the Third CISI Interval as defined by the Inspection Program. In accordance with Paragraph IW A-2430(c)(3), the inspection periods specified in these Tables may be decreased or extended by as much as I year to enable inspections to coincide with LSCS's refueling outages. The inspection of ISi Class CC components and tendons for the Third CISI Interval shall be performed in accordance with Paragraph IWL-2410 and IWL-2420.

Tables 1.1-3 and 1.1-4 identify the inspection schedule.

1.2 Background

The Commonwealth Edison Company, now known commercially as Exelon Generation Company, LLC (EGC), obtained Construction Permits to build LSCS on September 10, 1973, for Unit 1, CPPR-99, and for Unit 2, CPPR-100.

The Docket Numbers assigned to LSCS are 50-373 for Unit 1 and 50-374 for Unit 2. After satisfactory plant construction and preoperational testing was completed, LSCS was granted a full power operating license for Unit 1, NPF-11, and subsequently commenced commercial operation on January 1, 1984; the full power operating license for Unit 2, NPF-18, was granted and commercial operation commenced on October 17, 1984. LSCS's piping systems and associated components were designed and fabricated to be inspected and tested in accordance with the requirements of ASME Section XI. Although this plant was specifically designed to meet the inspection and testing requirements of ASME Section XI, literal compliance may not be feasible or practical within the limits of the current plant design. Certain limitations arc 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.

Implementation of the Subsection IWE and IWL Program from a scheduling standpoint was driven by the five year expedited implementation period per IOCFR50.55a(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, 200 I). ASME Section XI Subsections IWE, IWL, Mandatory Appendices of ASME Section XI, approved Code Cases, and approved alternatives through relief requests and SER's, and Inspection Program B were utilized in the ISi Program midway through the Second ISi Interval to implement these CISI requirements.

The First CISI Interval was initially scheduled from September 9, 1996 through September 9, 2008 for both LSCS Units 1 and 2. The baseline inspections for ISi Class CC concrete surfaces were perf armed on September 15, 1999 (LI R08) and September 18, 2000 (L2R08) for LSCS Units I and 2. These dates began the rolling inspection periods for both LSCS Units I and 2 for ISi Class CC concrete surfaces.

The baseline inspections for ISi Class CC post-tensioning system was determined based on the previous inspection dates under the Station Tendon Surveillance Program prior to Subsection IWL being endorsed by the NRC. These dates began the rolling inspection periods for both LSCS Units I and 2 for ISi Class CC concrete surfaces.

These original dates were based on the initial SIT tests. The CISI Program Plan was developed and implemented prior to the required date, and examinations for the first, second, and third periods were performed in accordance with the First CISI Interval schedule for LSCS Units I and 2. As detailed in Section 1.4, the transition from the First lo Second Interval CISI Program occurred approximately one year early for LSCS Units 1 and 2 to allow for a common interval date and Code of record between the ISi and CISI Programs.

To affect the synchronization and alignment between the LSCS Units I and 2 ISi and CISI Intervals, Paragraph IW A-2430(d) was used to adjust each inspection interval within the one year allowam:e.

Since the provisions of ASME Section XI Paragraph IW A-2430(d) were adhered to as required, a relief request was not necessary.

LSCS Calculation ATD-0204 (Reference 9.3. l 0) documents the determination of components or parts of components which can be exempted from the volumetric and surface examination requirements of Subarticle IWB-2500.

This determination was performed in accordance with the requirements of Paragraph IWB-1220.

The Performance Demonstration Initiative (POI) is an organization comprised of all United States (US) nuclear utilities that was formed to provide an efficient implementation of Appendix VIII performance demonstration requirements.

The EPRI Non-Destructive Examination (NOE) Center was selected as the administrator of this program. The POI Program is administered according lo the "POI Program Description." The ISi Program implements Appendix VIII "Performance Demonstration for Ultrasonic Examination Systems," ASME Section XI 2007 Edition with the 2008 Addenda with modilications as identilied in IOCFR50.55a(h)(2)(xiv).

Appendix Vlll requires qualification of' the procedures, personnel, and equipment used to detect and size flaws in piping, hohing, and the reactor pressure vessel (RPV). Each organization (e.g., owner or vendor) is required lo have a written program to ensure compliance with the requirements. LSCS maintains the rcsponsihility to ensure that Appendix VIII requirements arc properly implemented.

In accordance with ASME Section XI, ultrasonic exmninalions performed during the Fm111h ISi Interval, as required hy Paragraph IW A-2232, shall use the requirements idenlilied in Mandatory Appendix I, Ultrasonic Examinations.

/SI Program Plan LaSalle County Station Units I & 2, Fourth Interval These documents discuss the examination requirements for Intergranular Stress Corrosion Cracking (IGSCC) in BWR Austenitic Stainless Steel Piping. References to Generic Letter 88-0 I (GL 88-0 I) within the ISi Program refer to the comprehensive commitments to all of these documents.

The final SER's of BWRVIP-75 and BWRVIP-75-A revised the GL 88-01 inspection schedules.

The BWRVIP-75 and BWRVIP-75-A revised inspection schedules were based on consideration of inspection results and service experience gained by the industry since issuance of GL 88-0 I and NUREG-0313, and includes additional knowledge regarding the benefits of improved BWR water chemistry.

The original LSCS commitments concerning Generic Letter 88-01 were sent to the NRC in letters dated July 29, 1988, June 30, 1989, and November 5, 1990. The NRC reviewed these commitments in a letter dated August 22, 1990. Since the issuance of GL 88-0 I, the BWR Vessels and Internals Project (BWRVIP) has been created. This BWR owners group has worked on the mitigation of IGSCC for BWR internal components.

As part of their activities, EPRI Topical Report TR-113932, "BWR Vessel and Internals Project, Technical Basis for Revisions lo Generic Letter 88-01 Inspection Schedules (BWRVIP-75)," dated October 27, 1999, and EPRI Topical Report TR-1012621, "BWR Vessel and Internals Project, Technical Basis for Revisions to Generic Letter 88-01 Inspection Schedules (BWRVIP-75-A)," dated October 2005, were submitted to the NRC. Among other issues, this document proposed alternative inspection schedules for IGSCC susceptible welds. Two different inspection schedules were presented; one for plants on Normal Water Chemistry (NWC) and one for plants on effective Hydrogen Water Chemistry (HWC). The HWC schedule may he utili1.ed if the applicahle performance criteria arc met. After review of BWRVIP-75 and BWRVIP-75-A, the NRC issued SER's approving the documents with minor changes.

Execution of the surface assessment and improvement process should be performed within two outages prior to the scheduled examination.

The LSCS surface condition assessment and improvement process utilizes the applicable portions of the guidance provided in BWRVIP letter 2005-014 attachment 2, "Guidance for Establislzi11g DM Weld Qualijlc:atio11." These steps and others are incorporated in the Work Order planning and execution.

Examples can be found in Work Orders 744916 and 1229560. Based upon NRC endorsement of BWRVIP-75 and BWRVIP-75-A, the LSCS GL 88-01 (IGSCC) inspection schedule was updated to the requirements of BWRVIP-75 and BWRVIP-75-A except for Category A welds. (Sec Risk-Informed Inscrvicc Inspection discussion below and BWRVIP discussion in Section 2.2.4). RI-ISi regulations have been invoked for LSCS in this ISi Program Plan. Under these guidelines, ISi Class 1 and 2 piping structural clements are inspected in accordance with EPRI Topical Reports TR-112657, Rev. B-A, TR-I 006937. Rev. 0-A. and N-578-1. Per these Topical Reports and this Code Case, welds within the plant that arc assigned to IGSCC Categories B through G will continue to meet existing IGSCC schedules, while IGSCC Category A welds have been subsumed into the RI-ISi Program. The First Ten-Year inspection cycle for implementation of BWRVIP-75-A at LSCS Units I and 2 started on January I, 2003 and ended on December 31, 2012. The Second Tcn-Y car inspection cycle for implementation of BWRVIP-75-A al LSCS Units I and 2 started on January I, 2013 and will end on December 31, 2022. The IGSCC Progrnm has been revised lo schedule the re4uired examinations based on this inspection cycle. The NWC inspection schedule is credited; however, the effective HWC inspection schedule is not credited in the LSCS IGSCC Program.

This examination coverage was achieved using ultrasonic examination techniques conducted from the o.d. of the RPV. RPV shell welds AD (circumferential), B-K and B-M (longitudinal), exhibited limited examination coverage due to permanent physical obstructions.

Second ISi Interval Relief Request CR-38 was written by LSCS for the use of Technical Report TR-105697, "BWR Reactor Pressure Vessel Shell Weld Inspection Recommendations (BWRVIP-05)," Electric Power Research Institute, dated September 1995 for LSCS Units 1 and 2. Approval was authorized by the NRC for permanent relief of the RPV shell welds for the rest of the interval and the remaining term of the initial operating licenses (See below for more details). This Fourth IS I Interval augmented examination program addresses the specific steps taken by LSCS Units I and 2 to satisfy the NRC augmented examination requirements mandated by 10CFR50.55a(g)(6)(ii)(A), including alternatives agreed to by the NRC and EGC. The examinations of RPV shell welds, Examination Category 8-A, Item Number BI. I 0, at LSCS, will be conducted in accordance with Relief Request 14R-05. This Fourth ISi Interval Relief Request 14R-05 was previously submitted and approved under the Second Interval ISi Program Plan as Relief Request CR-38. The approval authorized under NRC final SER dated January 28, 2004 was for permanent relief and thu s applies to the remaining term of the initial operating licenses, including this Fourth ISi Interval.

BWRVIP is an association of BWR utilities focused on the common purpose of investigating and developing effective, acceptable approaches for addressing in-vessel component degradation through improved detection, mitigation, and/or repair techniques.

In accordance with the BWRVIP charter, the organization is tasked with providing generic resolution to BWR issues and representing the member utilities in negotiating with the NRC for approval of the groups' recommended actions. EGC, as a member utility of the BWRVIP, has endorsed the objectives prescribed by the BWRVIP. The BWRVIP is comprised of a series of Inspection

& Evaluation Guidelines and documents that discuss RPV internals.

The BWRVIP encompasses pertinent information and requirements presented in I.E. Bulletins (IEBs), General Electric (GE) Service Information Letters (SIL's), and Rapid Information Communication Services Information Letters (RICSIL's).

EGC's commitments to the BWRVIP arc discussed in BWRVIP letters to the NRC dated May 30, 1997 and October 30, 1997. The NRC's response to the discussion of BWRVIP utility commitments is discussed in an NRC letter to the BWRVIP dated July 29, 1997.

/SI Program Plan LaSalle County Station Units I & 2, Fourth Interval 2.3 System Classifications and P&ID Boundary Drawings The ISi Classification Basis Document details those systems that are ISi Class 1, 2, 3, or MC that fall within the ISi scope of examinations including the containment structure (metal and concrete) and post-tensioning system, which are ISi Class CC and are shown on the containment roll-out drawings.

Below is a summary of the classification criteria used within the ISi Classification Basis Document.

Each safety related, fluid system containing water, steam, air, oil, etc. included in the LSCS 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 ISi Class 1, 2, 3, MC, CC, or Non-Classed accordingly.

When a particular group of components is identified as performing an ISi Class I, 2, or 3 safety function, the components arc further reviewed to assure the interfaces (boundary valves and boundary barriers) meet the criteria set by IOCFR50.2, IOCFR50.55a(c}( 1), 10CFR50.55a(c)(2), and Regulatory Guide 1.26, Revision 3. SRP 3.2.2 and ANSl/ANS-58.14-1993 (LSCS is not committed to or licensed in accordance with these documents) were also used for guidance in evaluating the classification boundaries where I OCFR and the Regulatory Guide did not address a given situation.

According to I OCFR50.55a, Paragraph (g}(4 ), the ISi requirements of ASME Section XI urc assigned to these components, within the constraints of existing plant design. The LSCS ISi Class I, 2, and 3 components that arc exempt from examination arc those which meet the criteria of ASME Section XI, Paragraphs IWB-1220, IWC-1220. and IWD-1220. Supports which meet the criteria of Paragraph IWF-1230 of ASME Section XI arc also exempt from examination.

For Containment, IS I Class MC components which meet Paragraph IWE-1220 arc exempt from cxmnination, and ISi Class CC components which meet Paragraph IWL-1220 arc exempt from examination.

LSCS's ISi Program, including the ISi Database, ISi Classification Basis Document.

and ISi Selection Document and schedule, addresses the nonexempt components which require examination and testing. The systems and components (piping. pumps. valves. vessels. etc.). which arc subject to the cxmnim1tions of Articles IWB-2000, IWC-2<X>O, IWD-2<XX>.

and IWF-2CXX>. und pressure tests of Articles IWB-5000, IWC-50<X}, and IWD-5<XX>

arc identified on the Piping & Instrument Diagrums (P&ID's) und Control & Instrument Diagrams (C&ID's) within the ISi classification flags as detailed in Tables 2.3-1 and 2.3-2. The exempt components ure also identified on these diagrnms with various nag codes. 1"rw* .'V11rt/1 C"t111.mlti11R, /./.(' U\H 7". f Htlf>*ll-1 Hf'I*" ti UNIT 1 & Common M-55, SH.

Description:

Component Number: System Leakage Testing of Non-Isolable Buried Components Non-Isolable Buried Pressure Retaining Components Code Requirement IW A-5244(b)(2) requires non-isolable buried components be tested to confirm that llow during operation is not impaired.

Position IW A-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, LSCS has established the following acceptance criteria:

• For open ended lines on systems that require lnservice Testing (IST) or performance testing of pumps. adherence to IST or performance testing 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 llow discharging the line is considered as reasonable proof of adequate flow through the open ended line.

• For open ended prn1ions of systems where the process lluid is pneumatic, evidence of gaseous discharge shall he considered reasonable proof of adequate llow through the open ended line. Such test may include passing smoke through the line. hanging balloons or streamers, using a remotely operated hi imp. using thennogrnphy to detect hot air, etc. This m.:ceptance crite1fa will he utilized as proof of adeqtmte flow in order to meet the requirements of IW A-5244(b)(2).

LSCS's position is that proof of adClJUate flow is all that is rel1uired for testing the huried pipe segments of these open ended lines and that no fu11hcr visual examination is necessary.

This is consistent with the re4uirements for buried piping. which is not subject to visual examination.

Position LSCS 's position is that the test pressurization boundary extends up to the valve scat/disc of the valve utilized for isolation.

For example, in order to pressure test the ISi Class I 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 scat/disc.

Any requirement to test beyond the valve scat/disc is dependent only on whether or not the piping on the other side of the valve scat/disc is ISi Class I, 2, or 3. The extension of the test pressurization boundary during a pressure test would require an abnormal valve line-up. Extending the boundary would require the over pressurization of low pressure piping at systems tlmt have a high/low pressure interface.

In order to simplify examination of classed components.

LSCS will perform a VT-2 visual exmnination of the entire bmmdary valve body and bonnet (during pressurization up to the valve scat/disc).

E-A El. I I Examination of Leak Test Channels Various IWE-1220 states that the following components (or parts of components) are exempted from the examination requirements of IWE-2000, and IWE-1220(b) states that this applies to embedded or inaccessible portions of containment vessels, parts, and appurtances that met the requirements of the original Construction Code. Position Structural steel channel was fillet welded over a majority of LSCS liner scam welds and penetration welds to facilitate leak testing the scam welds after erection.

These channels make the liner surface underneath inaccessible for visual examination and therefore exempt per IWE-l 220(b ). During IOCFR50 Appendix J Type A testing, the leak test channels typically have their seal plugs removed to assure that these welds and adjacent liner surface arc challenged by the test pressure of the Containment Integrated Leak Rate Test (ILRT). In this situation, the leak test channels may be excluded from examination per Table IWE-2500-1, Examination Category E-A. Note l(b). LSCS, however, is not required to vent the containment liner leak test channels, except for the leak test channels around 18 embedment plates located in the suppression pool at elevation 706', during ILRT, Reference NRC Letter dated May 4, 1998, (TAC Nos. MAO 186 and MAO 187). The containment boundary has heen redelined to include the leak test channel surface instead of the inaccessible liner surface, since the leak test channels urc being challenged hy the ILRT instead of the liner surface. Accordingly.

the leak test channel surfaces will he treated as pressure retaining liner surface and examined in accordance with Tahlc IWE-2500-1, Examination Category E-A. Item Numhcr E 1.11. In addition, all other applicahle Suhsection IWE rc4uircmcnts arc mandatory for these surfaces. In addition, the suppression chamber lloor liner is also stiffened by channel shaped sections which cover (nmke inaccessible) additional liner surface urea heyond that covered hy the leak test channels.

These chtmncl shaped stiffeners were added to provide additional capacity to the lloor liner for resisting hydrodynamic uplift lm1ding. These channel shapes urc larger tlmn the lc.ak test channeb and surround small areas of the leak test channel system along the lloor. Similar to the leak test clmnncls, the stiffeners urc welded shut und urc challenged hy the ILRT pressure instead of the liner surface which it cover".

Component Number: Exclusion of Equipment Hatch and Personnel Air Lock Items Various Code Requirement IWE-1210 states that the examination requirements or Subsection IWE shall apply to ISi Class MC pressure retaining components and their integral attachments and to the metallic shell and penetration liners of ISi Class CC pressure retaining components and their integral attachments.

These examinations shall apply to surface areas, including welds and base metals. Position The Equipment Hatch and Personnel Air Lock have been identified as Subsection IWE components since they form portions of the containment leak tight barrier within their own penetrations.

These components each have an associated item which docs not meet the requirements or IWE-1210 and is therefore excluded from this progrnm. For the Equipment Hatch, this item is the overhead monornil support assembly and associated lifting lugs which arc welded to the hatch cover. The overhead monornil support assembly and associated lining lugs arc used only as a means to remove and install the Equipment Hatch and perform no other primary containment function as defined by this progrnm. For the Personnel Air Lock, this item is the mechanical locking mechanism.

The mechanical locking mechanism which opens and closes the door is only designed to seal the door against a pressure of 5 psig, while the door (i.e., door panel plus mounting hardware and lock) is designed for a containment accident pressure of 45 psig. Therefore, this component is excluded from the requirements of Subsection IWE. l"rru* ,\'11rtl1 C111u11/ti111:, /./.(" 1*4.1 /.SH14.fHll6*114 H1*1*/.d1111 II ISi Program Plan LaSalle County Station Units I & 2, Fourth Interval 3.0 COMPONENT ISi PLAN The LSCS Component ISi Plan includes ASME Section XI nonexempt pressure retaining welds, piping structural elements, pressure retaining bolting, welded attachments, pump casings, and valve bodies of ISi Class I, 2, and 3 components that meet the criteria of Subarticle IW A-1300.

This relief request allows for the implementation of a RI-ISi Program. Piping structural elements that fall under RI-ISi Examination Category R-A are risk ranked as High (I, 2, and 3), Medium (4 and 5), and Low (6 and 7). Per the EPRI Topical Reports TR-112657, Rev. B-A, TR-1006937, Rev. 0-A, and 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).

Thin wall welds that were excluded from volumetric examination under ASME Section XI rules per Table IWC-2500-1 are included in the piping structural element scope that is potentially subject to RI-ISi examination at LSCS. (LSCS has "thin wall" welds, but most of them were evaluated and ranked as Low Risk Category "6 or T'. Therefore, none of them were selected under RI-ISi.) Piping structural elements may be excluded from examination (other than pressure testing) under the RI-ISi Program if the only degradation mechanism present for a given location is inspected for cause under certain other LSCS programs such as the Flow Accelerated Corrosion (FAC) or IGSCC Programs.

These piping structural clements will remain part of the assigned programs, which already perform "for cause" inspections to detect these degradation mechanisms.

Piping structural clements susccptihlc to FAC or IGSCC along with another degradation mechanism (e.g .* thermal fatigue) arc retained as part of the RI-ISi scope and arc included in the clement selection for the purpose of performing examinations to detect the additional degradation mechanism.

RI-ISi piping structural elements, regardless of risk classification, remain subject to pressure testing as part of the current ASME Section XI program. The SPT ISi Plan performs system pressure tests and required VT-2 visual examinations on the ISi Class 1, 2, and 3 pressure retaining components to verify system and component structural integrity.

This program conducts both Periodic and Interval (10-Year frequency) pressure tests as defined in ASME Section XI Inspection Program. Procedure ER-AA-330-001, "Section XI Pressure Testing," as well as LSCS site-specific test procedures, implement the ASME Section XI System Pressure Testing ISi Plan. This System Pressure Testing ISi Plan also includes Augmented Examination Program requirements as referenced in Section 2.2 of this document.

5.1 ISi Class Systems All ISi Class 1 pressure retaining components, typically defined as the reactor coolant pressure boundary, are required to be tested. Those portions of IS I Class 2 and 3 systems that arc required to be tested include the pressure retaining boundaries of components required to operate or support the system safety functions.

ISi Class 2 open ended discharge piping and components arc excluded from the examination requirements per Paragraph IWC-5222(b).

IS/ Program Plan LaSalle County Station Units I & 2, Fourth Interval 8.0 RELIEF REQUESTS FROM ASME SECTION XI This section contains relief requests written per l OCFR50.55a(z)( l) for situations where alternatives to ASME Section XI requirements provide an acceptable level of quality and safety; per 10CFR50.55a(z)(2) for situations where compliance with ASME Section XI requirements results in a hardship or an unusual difficulty without a compensating increase in the level of quality and safety; per l OCFR50.55a(g)(5)(iii) for situations where ASME Section XI requirements are considered impractical; and for situations where use of a subsequent approved ASME Section XI Edition and Addenda is requested.

The following NRC guidance was utilized to determine the correct I OCFR50.55a paragraph citing for LSCS relief requests.

I OCFR50.55a(z)( I) and I OCFR50.55a(z)(2) provide alternatives to the requirements of ASME Section XI, while IOCFR50.55a(g)(5)(iii) recognizes situational impracticalities.

Examples arc relief requests which propose alternative NOE methods and/or examination frequency.

Cited in relief requests when compliance with the ASME Section XI requirements is deemed to he a hardship or unusual difficulty without a compensating increase in the level of quality and safety. Examples of hardship and/or unusual difficulty include, hut arc not limited to:

• Having to enter multiple Technical Specifications Limiting Conditions for Operation.

• As low as reasonahly achievahle (ALARA) concerns such as excessive radiation exposure.

• Replacing equipment or in-line components.

• Creating significant hazards to plant personnel,

• Disassemhly of components solely to provide access for examinations.

and

• Development of sophisticated tooling that would result in only minimal increases in examination coverage. Cited in relief rcl1ucsts when conformance with ASME Section XI requirements is deemed impractical.

Exmnplcs of impractical requirements arc situations where the component would have to he redesigned.
