ABSTRACT 

This document provides guidance on the content of applications for renewal of the initial renewed 

operating license. The initial renewed operating license is the first renewed license issued under 

Title 10 of the Code of Federal Regulations (10 CFR) Part 54, “Requirements for Renewal of 

Operating Licenses for Nuclear Power Plants,” after either supersession or the expiration of the 

original operating license issued under either 10 CFR Part 50 or Part 52 following the completion 

of construction under a construction permit issued under Part 50, or a combined license issued 

under Part 52. In this guidance document, the renewal of the initial renewed operating license is 

referred to as “subsequent license renewal” (SLR). NUREG–2191, “Generic Aging Lessons 

Learned for Subsequent License Renewal (GALL-SLR) Report,” provides guidance for SLR 

applicants. The GALL-SLR Report contains the U.S. Nuclear Regulatory Commission (NRC) 

staff’s generic evaluation of plant aging management programs (AMPs) and establishes the 

technical basis for their adequacy. The GALL-SLR Report contains recommendations on specific 

areas for which existing AMPs should be augmented for SLR. An applicant may reference this 

report in an SLR application to demonstrate that the AMPs at the applicant’s facility correspond to 

those described in the GALL-SLR Report. If an applicant credits an AMP in the GALL-SLR 

Report, it is incumbent on the applicant to ensure that the conditions and operating experience 

(OE) at the plant are bounded by the conditions and OE for which the GALL-SLR Report program 

was evaluated. If these bounding conditions are not met, it is incumbent on the applicant to 

address any additional aging effects and augment the AMPs for SLR. For AMPs that are based 

on the GALL-SLR Report, the NRC staff will review and verify whether the applicant’s AMPs are 

consistent with those described in the GALL-SLR Report, including applicable plant conditions 

and OE. The focus of the NRC staff’s review of an SLR application is on those AMPs that an 

applicant has enhanced to be consistent with the GALL-SLR Report, those AMPs for which the 

applicant has taken an exception to the program described in the GALL-SLR Report, and 

plant-specific AMPs not described in the GALL-SLR Report. 

This document is a companion document to NUREG–2192, “Standard Review Plan for Review of 

Subsequent License Renewal Applications for Nuclear Power Plants,” (SRP-SLR) that provides 

guidance to NRC staff on the review of SLR applications. The guidance in this document is for 

the use of future applicants for SLR. The NRC does not intend to impose the guidance in 

this document on current holders of an initial operating license. However, this document 

encompasses all of the guidance applicable to initial license renewal. Accordingly, both current 

holders of initial operating licenses as well as future applicants for initial license renewal may 

voluntarily choose to reference an AMP in the GALL-SLR Report in their applications. However, 

such applicants should inform the NRC that they plan to demonstrate consistency with the 

GALL-SLR Report. 

Both the GALL-SLR Report and the SRP-SLR were published for public comment in 

December 2015, with the comment period ending February 29, 2016. The staff received over 

300 pages of comments from interested stakeholders. These comments were reviewed and 

dispositioned by the staff. The disposition of these comments and the technical bases for the 

staffs’ agreement or disagreement with these comments will be published shortly in a NUREG. 

The staff will also publish a second NUREG that will document all the technical changes made to 

the license renewal guidance documents for first license renewal (i.e., for operation from 40 years 

to 60 years), along with the technical bases for these changes.

INTRODUCTION 

NUREG–2191, “Generic Aging Lessons Learned for Subsequent License Renewal 

(GALL-SLR) Report,” is referenced as a technical basis document in NUREG–2192, “Standard 

Review Plan for Review of Subsequent License Renewal Applications for Nuclear Power Plants,” 

(SRP-SLR). The GALL-SLR Report lists generic aging management reviews of systems, 

structures, and components (SSCs) that may be in the scope of subsequent license renewal 

applications (SLRAs) and identifies aging management programs (AMPs) that are determined to 

be acceptable to manage aging effects of SSCs in the scope of license renewal, as required by 

Title 10 of the Code of Federal Regulations (10 CFR) Part 54, “Requirements for Renewal of 

Operating Licenses for Nuclear Power Plants.” If an applicant credits an AMP described in the 

GALL-SLR Report in the SLRA, the applicant should ensure that the conditions and operating 

experience (OE) at the plant are bounded by the conditions and OE for which the GALL-SLR 

Report program was evaluated. If these bounding conditions are not met, the applicant should 

address any additional aging effects and augment the AMPs for subsequent license renewal. If 

an SLRA references the GALL-SLR Report as the approach used to manage aging effect(s), the 

U.S. Nuclear Regulatory Commission staff will use the GALL-SLR Report as a basis for the SLRA 

assessment consistent with guidance specified in the SRP-SLR. 

xxvii 

BACKGROUND 

The Atomic Energy Act (AEA) of 1954, as amended, allows the U.S. Nuclear Regulatory 

Commission (NRC) to issue licenses for commercial nuclear power reactors to operate for up to 

40 years. The NRC regulations permit these licenses to be renewed beyond the initial 40-year 

term for an additional period of time, limited to 20-year increments per renewal, based on the 

results of an assessment to determine if the nuclear facility can continue to operate safely during 

the proposed period of extended operation. There are no limitations in the AEA or the NRC 

regulations restricting the number of times a license may be renewed. 

The focus of license renewal, as described in Title 10 of the Code of Federal Regulations 

(10 CFR) Part 54, is to identify aging effects that could impair the ability of systems, structures, 

and components (SSCs) within the scope of license renewal to perform their intended functions, 

and to demonstrate that these effects will be adequately managed during the period of extended 

operation. The regulatory requirements for both initial and subsequent license renewal (SLR) are 

established by 10 CFR Part 54. To address the unique aspects of material aging and degradation 

that would apply to SLR (e.g., to permit plants to operate to 80 years), the Office of Nuclear 

Reactor Regulation requested support from the Office of Nuclear Regulatory Research (RES) to 

develop technical information to evaluate the feasibility of SLR. RES has memoranda of 

understanding with both the U.S. Department of Energy (DOE) and the Electric Power Research 

Institute to cooperate in nuclear safety research related to long-term operations beyond 60 years. 

Under these memoranda, the NRC and the DOE held two international conferences, in 2008 and 

2011, on reactor operations beyond 60 years. In May 2012, the NRC and the DOE also 

co-sponsored the Third International Conference on Nuclear Power Plant Life Management for 

Long-Term Operations, organized by the International Atomic Energy Agency (IAEA). In 

February 2013 and February 2015, the Nuclear Energy Institute (NEI) held a forum on long-term 

operations and SLR. These conferences laid out the technical issues that would need to be 

addressed to provide assurance for safe operation beyond 60 years. 

Based on the information gathered from these conferences and forums, and from other sources 

over the past several years, the most significant technical issues identified as challenging 

operation beyond 60 years are: reactor pressure vessel embrittlement; irradiation-assisted stress 

corrosion cracking (SCC) of reactor internals; concrete structures and containment degradation; 

and electrical cable environmental qualification, condition monitoring and assessment. 

Throughout this process, the NRC staff has emphasized that it is the industry’s responsibility to 

resolve these and other issues to provide the technical bases to ensure safe operation beyond 

60 years. 

The NRC, in cooperation with the DOE, completed the Expanded Materials Degradation 

Assessment (EMDA) in 2014 [Agencywide Documents Access and Management System 

(ADAMS) Accession Nos. ML14279A321, ML14279A331, ML14279A349, ML14279A430, and 

ML14279A461]. The EMDA uses an expert elicitation process to identify materials and 

components, which could be susceptible to significant degradation during operation beyond 

60 years. The EMDA covers the reactor vessel, primary system piping, reactor vessel internals, 

concrete, and electrical cables and qualification. The NRC staff used the results of the EMDA to 

identify gaps in the current technical knowledge or issues not being addressed by planned 

industry or DOE research, and to identify aging management programs (AMPs) that will require 

modification for SLR. 
xxviii 

On May 9, 2012 (ADAMS Accession No. ML12158A545) and subsequently on November 1, 

13, and 14, 2012, the NRC staff and interested stakeholders met to discuss issues and 

receive comments for consideration for SLR. The staff’s resolution to these public 

comments is available in the staff’s memo dated September 12, 2016 (ADAMS Accession 

No. ML16194A222). 

In addition to working with external stakeholders, the NRC staff conducted AMP effectiveness 

audits at three units that were at least 2 years into the period of extended operation. The purpose 

of these information gathering audits was to better understand how licensees are implementing 

the license renewal AMPs, in terms of both the findings and the effectiveness of the programs, 

and to develop recommendations for updating license renewal guidance. The NRC staff used the 

information gathered from these audits to update the SLR guidance based on the staff’s 

experience with the aging management activities during the first license renewals. A summary of 

the first two AMP effectiveness audits can be found in the May 2013 report, “Summary of Aging 

Management Program Effectiveness Audits to Inform Subsequent License Renewal: R.E. Ginna 

NPP and Nine Mile Point Nuclear Station, Unit 1” (ADAMS Accession No. ML13122A007). The 

summary of the third audit can be found in the August 5, 2014, report, “H.B. Robinson Steam 

Electric Plant, Unit 2, Aging Management Program Effectiveness Audit” (ADAMS Accession 

No. ML14017A289). In addition, on June 15, 2016, the staff issued the Technical Letter Report, 

“Review of Aging Management Programs: Compendium of Insight from License Renewal 

Applications and from AMP Effectiveness Audits Conducted to Inform Subsequent License 

Renewal Guidance Documents,” (ADAMS Accession No. ML16167A076), which provides the 

staff’s observations from reviewing license renewal applications and the AMP effectiveness 

audits. 

The NRC staff reviewed domestic operating experience (OE) as reported in licensee event reports 

and NRC generic communications related to failures and degradation of passive components. 

Similarly the NRC staff reviewed the following international OE databases: (i) International 

Reporting System, jointly operated by the IAEA; (ii) IAEA’s International Generic Ageing Lessons 

Learned Programme; (iii) Organisation for Economic Co-operation and Development 

(OECD)/Nuclear Energy Agency (NEA) Component Operational Experience and Degradation and 

Ageing Programme database; and (iv) OECD/NEA Cable Aging Data and Knowledge database. 

The NRC staff reviewed the results from AMP audits, findings from the EMDA, domestic and 

international OE, and public comments to identify technical issues that need to be considered for 

assuring the safe operation of NRC-licensed nuclear power plants (NPPs). By letter dated 

August 6, 2014 (ADAMS Accession No. ML14253A104), NEI documented the industry’s views 

and recommendations for updating NUREG–1801, Revision 2, “Generic Aging Lessons Learned 

(GALL) Report,” and NUREG–1800, Revision 2, “Standard Review Plan for Review of License 

Renewal Applications for Nuclear Power Plants,” to support SLR. Between fiscal years 2014 and 

2015, the NRC staff reviewed the comments and recommendations and drafted the Generic 

Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) Report to ensure that 

sufficient guidance was in place to support review of an SLR application in 2018 or 2019. 

The staff requirements memorandum (SRM) on SECY-14-0016, “Ongoing Staff Activities to 

Assess Regulatory Considerations for Power Reactor Subsequent License Renewal,” 

(ADAMS Accession No. ML14241A578) directed the staff to continue to update the license 

renewal guidance, as needed, to provide additional clarity on the implementation of the license 

renewal regulatory framework. The SRM also directed the staff to keep the Commission informed 

on the progress in resolving the following technical issues related to SLR: (i) reactor pressure 

vessel neutron embrittlement at high fluence, (ii) irradiation-assisted SCC of reactor internals 
xxix 

and primary system components, (iii) concrete and containment degradation, and (iv) electrical 

cable qualification and condition assessment. In addition, the SRM directed that the staff should 

keep the Commission informed regarding the staff’s readiness for accepting an application and 

any further need for regulatory process changes, rulemaking, or research. 

During the staff’s consideration of revisions to 10 CFR Part 54, changes were considered to the 

License Renewal Rule to address the provisions of 10 CFR 50.54(hh)(2) regarding guidance and 

strategies to maintain and restore core cooling, containment, and spent fuel cooling capabilities 

under the circumstances associated with the loss of large areas of the plant due to explosions or 

fires. After discussions with stakeholders and the public, it was concluded that these issues need 

not be addressed in the License Renewal Rule because emergency preparedness equipment is 

not identified in 10 CFR 54.4(a)(3). The 1995 Federal Register Notice for the final license renewal 

rule, 60 FR 22461, 22468 states: 

Regarding systems, structures, and components required to make protective 

action recommendations, the Commission thoroughly evaluated emergency 

planning considerations in the previous license renewal rulemaking. These 

evaluations and conclusions are still valid and can be found in the [Statements of 

Consideration] SOC for the previous license renewal rule (56 FR 64943 at 

64966). Therefore, the Commission concludes that systems, structures, and 

components required for emergency planning, unless they meet the scoping 

criteria in §54.4, should not be the focus of a license renewal review. 

Further, even if this equipment is within the scope of license renewal that does not necessarily 

mean that it is subject to aging management review based on the existing rule in that only 

passive, long-lived structures and components are subject to an aging management review. 

Further, this is not an issue specific to SLR and is inconsistent with the first principle of license 

renewal (i.e., “....with the exception of age-related degradation and possibly a few other issues 

related to safety only during extended operation of nuclear power plants, the existing regulatory 

process is adequate to ensure that the licensing bases of all currently operating plants provide 

and maintain an acceptable level of safety so that operation will not be inimical to public health 

and safety or common defense and security”). Therefore, there is no need to address 

10 CFR 50.54(hh) and diverse and flexible mitigation capability equipment in the License 

Renewal Rule. 

The GALL-SLR report also includes the NRC staff’s resolutions of License Renewal Interim Staff 

Guidance (LR-ISGs) from 2011 through 2016. Under the LR-ISG process, the NRC staff, 

industry, or stakeholders can propose a change to certain license renewal guidance documents. 

The NRC staff evaluates the issue, develops the proposed LR-ISG, issues it for public comment, 

evaluates any comments received, and, if necessary, issues the final LR-ISG. 

The LR-ISG is then used until the NRC staff incorporates the revised guidance into a formal 

license renewal guidance document revision. The LR-ISGs addressed in the GALL-SLR 

report are: 

 LR-ISG-2011-01: Aging Management of Stainless Steel Structures and Components in 

Treated Borated Water, Revision 1

OVERVIEW OF THE GENERIC AGING LESSONS LEARNED FOR 

SUBSEQUENT LICENSE RENEWAL (GALL-SLR) REPORT 

EVALUATION PROCESS 

The Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) Report 

contains 11 chapters and 2 appendices. The majority of the chapters contain summary 

descriptions and tabulations of evaluations of aging management programs (AMPs) for a large 

number of structures and components (SCs) in major plant systems found in light-water reactor 

nuclear power plants. The major plant systems include the containment structures (Chapter II), 

SC supports (Chapter III), reactor vessel, internals and reactor coolant system (Chapter IV), 

engineered safety features (Chapter V), electrical components (Chapter VI), auxiliary systems 

(Chapter VII), and steam and power conversion system (Chapter VIII). 

Chapter I of the GALL-SLR Report addresses the application of the American Society of 

Mechanical Engineers Boiler and Pressure Vessel Code for subsequent license renewal (SLR). 

Chapter IX contains the description of a selection of standard terms used within the GALL-SLR 

Report. Chapter X contains examples of AMPs that may be used to demonstrate the acceptance 

of time-limited aging analyses (TLAAs) in accordance with Title 10 of the Code of Federal 

Regulations (10 CFR) 54.21(c)(1)(iii). Chapter XI contains the AMPs for the mechanical, 

structural and electrical components. The appendices of the GALL-SLR Report address quality 

assurance for AMPs and operating experience (OE). 

The evaluation process for the AMPs and the application of the GALL-SLR Report is described in 

this document. The aging management review (AMR) items for the GALL-SLR Report are 

presented in tabular format as described in Table 1. Table 1 describes the information presented 

in each column of the tables in Chapters II through VIII contained in this report. 

The staff’s evaluation of the adequacy of each generic AMP to manage certain aging effects for 

particular SCs is based on its review of the 10 program elements in each AMP, as defined in 

Table 2. 

On the basis of its evaluation, if the staff determines that a program is adequate to manage 

certain aging effects for a particular SC without change, the “Further Evaluation” entry will indicate 

that no further evaluation is recommended for SLR. 

Chapters X and XI of the GALL-SLR Report contain generic AMPs that the staff finds to be 

sufficient to manage aging effects in the subsequent period of extended operation, such as the 

ASME Code Section XI inservice inspection, water chemistry, or structures monitoring program.

Table 1. Aging Management Review Column Heading Descriptions 

Column Heading Description 

New (N), Modified (M), Deleted (D), 

Edited (E) Item 

Identifies the item as new to GALL-SLR Report, modified from 

GALL Revision 2, deleted from GALL Revision 2, edited from 

GALL Revision 2, or if blank, is unchanged from GALL 

Revision 2. 

Item Identifies a unique number for the item (i.e., VII.G.A-91). The 

first part of the number indicates the chapter and AMR system 

(e.g., VII.G is in the auxiliary systems, fire protection system), 

and the second part is a unique chapter-specific identifier within 

a chapter (e.g., A–91 for auxiliary systems). 

Standard Review Plan (SRP) Item 

(Table, ID) 

For each row in the subsystem tables, this item identifies the 

corresponding row identifier from the SRP-SLR to provide the 

crosswalk to the SRP system table items. 

Structure and/or Component Identifies the structure or components to which the row applies. 

Material Identifies the material of construction. See Chapter IX.C of this 

report for further information. 

Environment Identifies the environment applicable to this row. 

See Chapter IX.D of this report for further information. 

Aging Effect/ Mechanism Identifies the applicable aging effect and mechanism(s). 

See Chapters IX.E and IX.F of this report for more information on 

applicable aging effects/mechanisms. 

Aging Management Program 

(AMP)/TLAA 

Identifies an AMP/TLAA found acceptable for adequately 

managing the effects of aging. See Chapters X and XI of this 

report. 

Further Evaluation Identifies whether a further evaluation is needed. 

Edited (E) items, in contrast to modified (M) items, are those for which no technical aspects were 

changed. Examples of editorial changes include: 

 Line item citations that were missed in the SRP SLR Table 3.X-1. 

 Deleting whether the environment is internal or external from the description of the 

environment because based on the material, environment, aging effect, and AMP 

combination, it is obvious that the environment could only be on either the inside or 

outside of the component. 

 Deletion of the term “piping element” from aging management review items that do not cite 

glass as a material. Piping elements were defined in the GALL Report as components 

constructed of glass. 

 Line item changes that only involved removing detail related to a Further Evaluation 

Recommended column was removed after it was verified that the identical information was 

included in the SRP-SLR further evaluation section. 

 Line item changes that only involved renumbering further evaluation sections. 
xxxiii 

 Aging effects changed from “and” to “or.” This could appear to be a technical change; 

however, this is not the case because the staff confirmed that is was never the intent that 

both aging effects were occurring. For example, the “and” in cracking due to stress 

corrosion cracking and cyclic loading was replaced with “or.” 

 Deleting the term “environment” from the description of the environment in the 

“Environment” column when the phrase “any environment” was used because it was 

obvious and redundant. 

 Descriptors for the AMPs in the “Aging Management Program/TLAA” column were 

simplified if the information was provided elsewhere. 

 Minor edits to component descriptions, examples: (a) deleting “elastomer” from 

“elastomer, elastomer seals;” (b) adding “piping” or “ducting” in front of the term 

“component.”

Table 2. Aging Management Programs Element Descriptions 

AMP Element Description 

1. Scope of the Program The scope of the program should include the specific structures and 

components subject to an AMR. 

2. Preventive Actions Preventive actions should mitigate or prevent the applicable 

aging effects. 

3. Parameters Monitored 

or Inspected 

This identifies the aging effects that the program manages and 

provides a link between the parameter or parameters that will be 

monitored and how the monitoring of these parameters will maintain 

adequate aging management. 

4. Detection of Aging Effects Detection of aging effects should occur before there is a loss of any 

structure and component intended function. This element describes 

aspects such as method or technique (i.e., visual, volumetric, 

surface inspection), frequency, sample size, data collection, and 

timing of new/one-time inspections to ensure timely detection of 

aging effects. 

5. Monitoring and Trending Monitoring and trending should provide for an estimate of the extent 

of the effects of aging and timely corrective or mitigative actions. 

6. Acceptance Criteria Acceptance criteria, against which the need for corrective action will 

be evaluated, should provide reasonable assurance that the 

particular structure and component’s intended functions are 

maintained under all current licensing basis conditions during the 

subsequent period of extended operation. 

7. Corrective Actions Description of corrective actions that will be implemented if the 

acceptance criteria of the program are not met. 

8. Confirmation Process The confirmation process should provide reasonable assurance that 

preventive actions are adequate and that appropriate corrective 

actions have been completed and are effective. 

9. Administrative Controls Administrative controls should provide a formal review and approval 

process. 

10. Operating Experience (OE) OE applicable to the AMP, including past corrective actions resulting 

in program enhancements or additional programs, should provide 

objective evidence to support the conclusion that the effects of aging 

will be managed adequately so that the structure- and component 

intended function(s) will be maintained during the subsequent period 

of extended operation. In addition, an ongoing review of both 

plant-specific and industry OE provides reasonable assurance that 

the AMP is effective in managing the aging effects for which it is 

credited. The AMP is either enhanced or new AMPs are developed, 

as appropriate, when it is determined through the evaluation of OE 

that the effects of aging may not be adequately managed. 
xxxv 

EXPLANATION OF THE USE OF MULTIPLE AGING MANAGEMENT 

PROGRAMS IN AGING MANAGEMENT REVIEW ITEMS 

For aging management review (AMR) items associated with some “Further Evaluations,” the 

associated Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) 

Report items now include a letter suffix with the unique chapter-specific identifier. For these 

items, the staff designated the various aging management programs (AMPs) it found to be 

acceptable in lieu of specifying “plant-specific aging management program” in the Aging 

Management Program column. Depending on the GALL-SLR Report Table 2 item cited in the 

subsequent license renewal application (SLRA) for these items, applicants can either use one of 

the AMPs found to be acceptable to the staff for specific situations or, comparable to any other 

item, can propose their own plant-specific program to manage the associated aging effect. 

For example, Standard Review Plan for Review of Subsequent License Renewal Applications for 

Nuclear Power Plants (SRP-SLR) Section 3.1.2.2.16 is a further evaluation associated with 

SRP-SLR item 3.1-1, 136, for loss of material due to pitting and crevice corrosion in stainless steel 

and nickel alloy piping and piping components. The associated chapter-specific identifier has 

been expanded to include items R-452a, R-452b, R-452c, and R-452d. The further evaluation 

recommends a review of plant-specific operating experience (OE) to determine if the site’s air 

environments are sufficiently aggressive to cause pitting and crevice corrosion. The need to 

manage this aging effect will depend on the results of the OE reviews and a one-time inspection 

to demonstrate that pitting and crevice corrosion are not occurring or are occurring sufficiently 

slowly. Consequently, the acceptable AMP could be XI.M32 for performing the one-time 

inspection (if the aging effect does not need to be periodically managed), or it could be XI.M36, 

XI.M38, or XI.M42, depending on whether a periodic program is needed for external surfaces, 

internal surfaces, or coatings/linings. The SLRA will specify the applicable AMP by citing the 

specific GALL-SLR item R-452a, R-452b, R-452c, or R-452d for the corresponding AMP being 

used at the site. More specifically, if the plant-specific OE review does not reveal any instances 

of loss of material for stainless steel or nickel alloy piping and piping components, R-452a 

(AMP XI.M32) would be the cited SLRA AMR Table 2 item. In contrast, if external loss of 

material has occurred, and it was sufficient to potentially affect the intended function, R-452b 

(AMP XI.M36) or R-452d (AMP XI.M42) would be cited.

REFERENCES 

References are listed in the aging management program (AMP) following the program elements. 

References consist of documents (e.g., Codes, Standards) associated with recommended actions 

(e.g., qualification of personnel, inspection methods) cited in the program elements or documents 

containing background information associated with the AMP (e.g., Information Notices). The 

specific version (e.g., edition, addenda, revision) of a reference is cited in the list of references. It 

should be noted that in some instances, specific program elements might cite a different version 

of a reference than that cited in the reference list. In these cases, the staff has reviewed the 

provisions of the different version of the reference and has specifically cited a version based on 

the requirements or guidance contained within the document. Where a specific version is not 

cited in a program element, the version cited in the reference list is applicable. With the exception 

of the guidance on use of later editions/revisions of various industry documents cited below, an 

applicant should identify exceptions to the Generic Aging Lessons Learned for Subsequent 

License Renewal (GALL-SLR) Report and provide justification when using a different version of a 

reference cited in the program elements. 

xxxix 

GUIDANCE ON USE OF LATER EDITIONS/REVISIONS OF 

VARIOUS INDUSTRY DOCUMENTS 

To aid applicants in the development of their subsequent license renewal applications (SLRAs), 

the staff has developed a list of aging management programs in the Generic Aging Lessons 

Learned for Subsequent License Renewal (GALL-SLR) Report that are based entirely or in 

part on specific editions/revisions of various industry codes (other than the American Society 

of Mechanical Engineers Boiler and Pressure Vessel Code), standards, and other 

industry-generated guidance documents. SLRAs may use later editions/revisions of these 

industry generated documents, subject to the following provisions: 

(i) If the later edition/revision has been explicitly reviewed and approved/endorsed by the 

U.S. Nuclear Regulatory Commission (NRC) staff for license renewal via a NRC 

Regulatory Guide endorsement, a safety evaluation for generic use [such as for a Boiling 

Water Reactor Vessel and Internals Project (BWRVIP)], incorporation into Title 10 of the 

Code of Federal Regulation (10 CFR), or license renewal interim staff guidance. 

(ii) If the later edition/revision has been explicitly reviewed and approved on a plant-specific 

basis by the NRC staff in its Safety Evaluation Report for another applicant’s SLRA 

(a precedent exists). Applicants may reference this and justify applicability to their facility 

via the exception process in Nuclear Energy Institute 95-10. 

If either of these methods is used as justification for adopting a later edition/revision than specified 

in the GALL-SLR Report, the applicant shall reference the information pertaining to the NRC 

endorsement/approval of the later edition/revision. 

xli 

APPLICATION OF THE GENERIC AGING LESSONS LEARNED FOR 

SUBSEQUENT LICENSE RENEWAL (GALL-SLR) REPORT 

The Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) Report is a 

technical basis document to the Standard Review Plan for Review of Subsequent License 

Renewal Applications for Nuclear Power Plants (SRP-SLR), which provides the staff with 

guidance in reviewing a subsequent license renewal application (SLRA). The GALL-SLR Report 

should be treated in the same manner as an approved topical report that is generically applicable. 

An applicant may reference the GALL-SLR Report in an SLRA to demonstrate that the aging 

management programs (AMPs) at the applicant’s facility correspond to those reviewed and 

approved in the GALL-SLR Report. 

If an applicant takes credit for an AMP in GALL-SLR Report, it is incumbent on the applicant to 

ensure that the plant AMP contains all the elements of the referenced GALL-SLR program. In 

addition, the conditions and operating experience (OE) at the plant must be bounded by the 

conditions and OE for which the GALL-SLR Report AMP was evaluated; otherwise it is incumbent 

on the applicant to augment the GALL-SLR Report AMP as appropriate to address the impact of 

the plant-specific OE on the AMP element criteria. The documentation for the above verifications 

must be available onsite in an auditable form. 

The GALL-SLR Report contains one acceptable way to manage aging effects for subsequent 

license renewal (SLR). An applicant may propose alternatives for staff review in its plant-specific 

SLRA. The use of the GALL-SLR Report is not required, but its use should facilitate both 

preparation of an SLRA by an applicant and timely, consistent review by the U.S. Nuclear 

Regulatory Commission staff. 

The GALL-SLR Report does not address scoping of structures and components (SCs) for license 

renewal; this is addressed in SRP-SLR Chapter 2. Scoping is plant-specific, and the results 

depend on the plant design and current licensing basis. The inclusion of a certain structure or 

component in the GALL-SLR Report does not imply that this particular structure or component is 

within the scope of license renewal for all plants. Conversely, the omission of a certain structure 

or component in the GALL-SLR Report does not imply that this particular structure or component 

is not within the scope of SLR for any plants. 

The GALL-SLR Report contains an evaluation of a large number of SCs that may be in the scope 

of a typical SLRA. The evaluation results documented in the GALL-SLR Report indicate that 

many existing, typical generic AMPs are adequate to manage aging effects for particular 

structures or components for SLR without change. The GALL-SLR Report also contains 

recommendations on specific areas for which existing generic AMPs should be augmented 

(require further evaluation) for SLR and documents the technical basis for each such 

determination. The GALL-SLR Report identifies certain systems, structures, and components 

(SSCs) that may or may not be subject to particular aging effects, and those for which industry is 

developing generic AMPs or investigating whether aging management is warranted. 

Appendix A of the GALL-SLR Report addresses quality assurance (QA) for AMPs. Those aspects 

of the aging management review (AMR) process that affect the quality of safety-related SSCs are 

subject to the QA requirements of Appendix B to Title 10 of the Code of Federal Regulations 

(10 CFR) Part 50. For nonsafety-related SCs subject to an AMR, the existing 10 CFR Part 50, 

Appendix B, QA program may be used by an applicant to address the elements of the corrective 

actions, confirmation process, and administrative controls for an AMP for SLR. 
xlii 

The GALL-SLR Report provides a technical basis for crediting existing plant AMPs and 

recommending areas for AMP augmentation and further evaluation. The incorporation of the 

GALL-SLR Report information into the SRP-SLR, as directed by the Commission, should improve 

the efficiency of the SLR review process and the use of staff resources. 
CHAPTER I 

APPLICATION OF THE AMERICAN SOCIETY OF MECHANICAL 

ENGINEERS BOILER AND PRESSURE VESSEL CODE 

I-1 

I APPLICATION OF THE AMERICAN SOCIETY OF MECHANICAL 

ENGINEERS BOILER AND PRESSURE VESSEL CODE 

The American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code), 

Division 1, Sections III (design) and XI (inservice inspection requirements) were developed and 

are revised periodically by industry code committees composed of representatives of utilities, 

reactor designers, architect-engineers, component manufacturers, insurance companies, the 

U.S. Nuclear Regulatory Commission (NRC), and others. In 1971, the Atomic Energy 

Commission (AEC), the predecessor of the NRC, incorporated the ASME Code into the 

regulations in Title 10 of the Code of Federal Regulations (10 CFR) 50.55a through issuance of 

the Federal Register Notice (FRN) for the final rule (36 FR 11423 [June 12, 1971]). 

The statements of consideration (SOC) for the initial issuance of 10 CFR 50.55a provides the 

bases for AEC’s endorsement and use of the ASME Code: 

It has been generally recognized that, for boiling and pressurized water-cooled 

reactors, pressure vessels, piping, pumps, and valves which are part of the reactor 

coolant pressure boundary should, as a minimum, be designed, fabricated, 

inspected, and tested in accordance with the requirements of the applicable 

American Society of Mechanical Engineers (ASME) codes in effect at the time the 

equipment is purchased[.] 

Because of the safety significance of uniform early compliance by the nuclear 

industry with the requirements of these ASME codes and published code revisions, 

the Commission has adopted the following amendments to Part 50 and 115, which 

require that certain components and systems of water-cooled reactors important to 

safety comply with these codes and appropriate revisions to the codes at the 

earliest feasible time. 

Compliance with the provisions of the amendments and the referenced codes is 

intended to insure a basic, sound quality level. 

These ASME Code sections are based on the collective engineering judgment of the code 

committees and document the conditions that must be monitored, the inspection techniques to 

identify those conditions, the frequency of the inspections, and the acceptance criteria that the 

inspection results must meet in order to assure the integrity of the structures and components 

considered in the code. The NRC has accepted this engineering judgment by endorsing the use 

of selected sections of the ASME Code, as incorporated in 10 CFR 50.55a. 

In addition, the NRC periodically amends 10 CFR 50.55a and issues FRNs about this rule in order 

to endorse, by reference, newer editions and ASME Code addenda subject to the modifications 

and limitations identified in 10 CFR 50.55a. As stated in 65 FR 53050 (August 31, 2000): 

To ensure that the GALL report conclusions will remain valid when future 

editions of the ASME Code are incorporated into the NRC regulations by the 

10 CFR 50.55a rulemaking, the staff will perform an evaluation of these later 

editions for their adequacy for license renewal using the 10-element program 

evaluation described in the GALL Report as part of the 10 CFR 50.55a rulemaking. 
I-2 

The staff will continue to evaluate future editions of the ASME Code for their adequacy for 

subsequent license renewal, and will document this evaluation in the SOC accompanying future 

10 CFR 50.55a amendments, which will be published in a FRN. 

References to American Society of Mechanical Engineers Boiler and Pressure 

Vessel Code Section XI Used in This Report 

To aid applicants in the development of their subsequent license renewal applications (SLRAs), 

the staff has developed a list of aging management programs (AMPs) in the Generic Aging 

Lessons Learned for Subsequent License Renewal (GALL-SLR) Report that are based on 

consistency with the 10-program element criteria defined in Section A.1.2.3 of the Standard 

Review Plan for Review of Subsequent License Renewal Applications for Nuclear Power Plants 

(SRP-SLR). Some of the AMPs referenced in the GALL-SLR Report are based entirely or in part 

on compliance with the requirements of ASME Code Section XI, as endorsed for use through 

reference in 10 CFR 50.55a. In addition, in some cases, the staff has determined that specific 

requirements in ASME Code Section XI need to be augmented to ensure adequate aging 

management consistent with the requirements of the License Renewal Rule. Thus, some of the 

AMPs in the GALL-SLR Report also provide guidance on augmenting the requirements of ASME 

Code Section XI. The staff has determined that in most cases the ASME Code Section XI 

requirements referenced in Table I-1 provide an acceptable basis for managing the effects of 

aging during the subsequent period of extended operation, except where noted and augmented in 

the GALL-SLR Report. Therefore, except where noted (see below) and augmented in the 

GALL-SLR Report, the ASME Code Section XI editions and addenda listed in Table I-1, subject to 

the modifications and limitations in 10 CFR 50.55a, should be treated as consistent with the 

GALL-SLR Report, and an applicant need not identify exceptions when using these specific 

editions and addenda. It should be noted that in some instances, AMPs have been augmented by 

referencing an edition or addenda beyond that referenced in Table I-1. In these cases, the staff 

has reviewed the provisions of the later code and has specifically cited the later edition or 

addenda based on the requirements contained within that version of ASME Code Section XI. In 

order for an applicant’s program to be consistent with such an AMP, the later edition and addenda 

should be cited. 

An applicant should identify exceptions to the GALL-SLR Report and provide justification when 

using any ASME Code Section XI edition or addenda not listed in Table I-1 or specifically cited in 

a GALL-SLR Report AMP. With respect to more recent (beyond those already cited in a 

GALL-SLR Report AMP) ASME Code Section XI editions and addenda, the NRC will update 

Table I-1 through either a published revision to the GALL-SLR Report or through the license 

renewal interim staff guidance process after the staff has evaluated the specific ASME Code 

Section XI edition or addendum and determined the extent to which it is adequate for 

license renewal. 

Updates to the American Society of Mechanical Engineers Code of Record During 

U.S. Nuclear Regulatory Commission’s Review of Subsequent License 

Renewal Applications 

Pursuant to 10 CFR 50.55a(g)(4), a nuclear licensee is required to amend its current licensing 

basis (CLB) by updating its ASME Code Section XI edition and addenda of record to the most 

recently endorsed edition and addenda referenced in 10 CFR 50.55a one year prior to entering 

the next 10-year inservice inspection interval for its unit. Pursuant to 10 CFR 54.21(b), an 

applicant for license renewal is required to periodically submit updates of its SLRA to identify any 

changes in its CLB that materially affect the contents of the SLRA. The rule requires an update of 
I-3 

the SLRA each year following the submittal of the application and an additional update 3 months 

prior to the completion of the NRC’s review of the SLRA. If an applicant’s ASME Code Section XI 

edition of record is updated under the requirements of 10 CFR 50.55a(g)(4) during the NRC’s 

review of the SLRA, the applicant should update those AMPs in the SLRA that are impacted by 

this change in the CLB when the applicant submits the next update of the SLRA required by 

10 CFR 54.21(b). 

Effective Period for Approved Relief Requests and Code Cases 

The current regulatory process, including 10 CFR 50.55a, continues into the subsequent period of 

extended operation. The NRC Director of the Office of Nuclear Reactor Regulation may authorize 

a licensee-proposed alternative to ASME Code Section XI if it is submitted as an alternative in 

accordance with 10 CFR 50.55a(a)(3). The staff’s authorization of an alternative program typically 

does not extend beyond the current 10-year interval for which the alternative was proposed. For 

cases in which this interval extends beyond the renewed license period into the subsequent 

period of extended operation, the approved alternative remains in effect until the end of that 

interval, consistent with the specific approval (60 FR 22461, 22483). 

Pursuant to 10 CFR 50.55a(b)(5), licensees may apply ASME Code Cases listed in NRC 

Regulatory Guide (RG) 1.147, through the most recent endorsed revision, without NRC 

authorization, subject to the limitations contained in the rule. The rule permits licensees to 

continue to apply the Code case, or a most recent version that is incorporated by the RG, until the 

end of the 10-year interval. For cases in which this interval extends beyond the renewed license 

period into the subsequent renewed license period, the Code case, or a more recent endorsed 

version, remains in effect until the end of that interval, consistent with 10 CFR 50.55a(b)(5) and 

the statements of consideration for the final License Renewal Rule 60 FR 22461.

(ii) steel, and (iii) prestressing systems. 

System Interfaces 

Functional interfaces include the primary containment heating and ventilation system (VII.F3), 

containment isolation components (V.C), and the containment spray system (V.A). Physical 

interfaces exist with any structure, system, or component that either penetrates the containment 

wall, such as the main steam (MS) system (VIII.B1) and the feedwater (FW) system (VIII.D1), or is 

supported by the containment structure, such as cranes (VII.B). The containment structure 

basemat typically provides support to the nuclear steam supply system components and 

containment internal structures.

A2. STEEL CONTAINMENTS 

Systems, Structures, and Components 

This section addresses the elements of pressurized water reactor (PWR) steel containment 

structures. Steel containment structures are divided into two elements: (i) steel and (ii) concrete. 

System Interfaces 

Functional interfaces include the primary containment heating and ventilation system (VII.F3), 

containment isolation components (V.C), and the containment spray system (V.A). Physical 

interfaces exist with any structure, system, or component that either penetrates the containment 

wall, such as the main steam (MS) system (VIII.B1) and the feedwater (FW) system (VIII.D1), or is 

supported by the containment structure, such as cranes (VII.B). The containment structure 

basemat typically provides support to the nuclear steam supply system components and 

containment internal structures.

Systems, Structures, and Components 

This section addresses the elements of the boiling water reactor (BWR) reactor building, 

pressurized water reactor (PWR) shield building, and control room/building. For this group, the 

applicable structural elements are concrete, steel, and masonry walls. The aging management 

review (AMR) is presented for each applicable combination of structural element and aging effect. 

System Interfaces 

Physical interfaces exist with any system or component that either penetrates the structure wall or 

is supported by the structure wall, floor, and roof. The direct interface is through the system or 

component supports that are anchored to the structure. Structures also protect housed systems 

or components from internal and external design basis events. In the case of tanks, there is a 

functional interface with the associated system. Water-control structures are integral parts of the 

systems that provide plant cooling water and residual heat removal.

Systems, Structures, and Components 

This section addresses the elements of the fuel storage facility and refueling canal. For this 

group, the applicable structural elements are identified: (i) concrete, (ii) steel, and (iii) masonry 

walls. The aging management review (AMR) is presented for each applicable combination of 

structural element and aging effect. 

System Interfaces 

Physical interfaces exist with any system or component that either penetrates the structure wall or 

is supported by the structure wall, floor, and roof. The direct interface is through the system or 

component supports that are anchored to the structure. Structures also protect housed structures 

and components from internal and external design basis events. In the case of tanks, there is a 

functional interface with the associated system. Water-control structures are integral parts of the 

systems that provide plant cooling water and residual heat removal.

A8. GROUP 8 STRUCTURES (STEEL TANKS AND MISSILE BARRIERS) 

Systems, Structures, and Components 

This section addresses the elements of steel tanks and missile barriers. For this group, the 

applicable structural elements are identified: (i) concrete and (ii) steel. The aging management 

review (AMR) is presented for each applicable combination of structural element and aging effect. 

System Interfaces 

Physical interfaces exist with any system or component that either penetrates the structure wall or 

is supported by the structure wall, floor, and roof. The direct interface is through the system or 

component supports that are anchored to the structure. Structures also protect housed structures 

and components from internal and external design basis events. In the case of tanks, there is a 

functional interface with the associated system. Water-control structures are integral parts of the 

systems that provide plant cooling water and residual heat removal.

Boiler and Pressure Vessel Code (ASME Code) piping systems and components. It is subdivided 

into Class 1 (III.B1.1), Class 2 and Class 3 (III.B1.2), and Class MC (III.B1.3). Applicable aging 

effects are identified and the aging management review (AMR) is presented for each applicable 

combination of support component and aging effect. 

System Interfaces 

Physical interfaces exist with the structure, system, or component being supported and with the 

building structural element to which the support is anchored. A primary function of supports is to 

provide anchorage of the supported element for internal and external design basis events so that 

the supported element can perform its intended function.

Systems, Structures, and Components 

This section addresses the boiling water reactor (BWR) pressure vessel and consists of the 

vessel shell and flanges, attachment welds, top and bottom heads, nozzles (including safe ends) 

for the reactor coolant recirculating system and connected systems (such as high and low 

pressure (LP) core spray, high and LP coolant injection, main steam (MS), and feedwater (FW) 

systems), penetrations for control rod drive (CRD) stub tubes, instrumentation, standby liquid 

control (SLC), flux monitor, drain lines, and CRD mechanism housings. The support skirt and 

attachment welds for vessel supports are also included in the following table for the BWR vessel. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all structures 

and components that comprise the reactor vessel are governed by Group A Quality Standards. 

Common miscellaneous material/environment combinations where aging effects are not expected 

to degrade the ability of the structure or component to perform its intended function for the 

subsequent period of extended operation are included in IV.E. 

System Interfaces

The systems that interface with the reactor vessel include the reactor vessel internals (RVIs) 

(IV.B1), the reactor coolant pressure boundary (RCPB) (IV.C1), the emergency core cooling 

system (ECCS) (V.D2), and the standby liquid control (SLC) system (VII.E2).

B2. REACTOR VESSEL INTERNALS (PRESSURIZED WATER REACTOR)—

WESTINGHOUSE 

Systems, Structures, and Components 

This section addresses the Westinghouse pressurized water reactor (PWR) vessel internals, 

which consist of components in the upper internals assembly, the control rod guide tube (CRGT) 

assembly, the core barrel (CB) assembly, the baffle/former assembly, the lower internals 

assembly, lower support assembly, thermal shield assembly, bottom mounted instrumentation 

system, and alignment and interfacing components. 

Common miscellaneous material/environment combinations where aging effects are not expected 

to degrade the ability of the structure or component to perform its intended function for the 

subsequent period of extended operation are included in IV.E. 

System Interfaces 

The systems that interface with the reactor vessel internals include the reactor pressure 

vessel (RPV) (IV.A2).

B3. REACTOR VESSEL INTERNALS (PRESSURIZED WATER REACTOR)—

COMBUSTION ENGINEERING 

Systems, Structures, and Components 

This section addresses the Combustion Engineering (CE) pressurized water reactor (PWR) 

vessel internals, which consist of components in the upper internals assembly, the control element 

assembly (CEA), the core support barrel assembly, the core shroud assembly, and the lower 

support structure assembly, and incore instrumentation components. 

Common miscellaneous material/environment combinations where aging effects are not expected 

to degrade the ability of the structure or component to perform its intended function for the 

subsequent period of extended operation are included in IV.E. 

System Interfaces 

The systems that interface with the reactor vessel internals include the reactor pressure vessel 

(RPV) (IV.A2).

B4. REACTOR VESSEL INTERNALS (PRESSURIZED WATER REACTOR) – 

BABCOCK AND WILCOX 

Systems, Structures, and Components 

This section addresses the Babcock & Wilcox (B&W) pressurized water reactor (PWR) vessel 

internals, which consist of components in the plenum cover assembly, the upper grid assembly, 

the control rod guide tube (CRGT) assembly, the core support shield assembly, the core barrel 

(CB) assembly, the lower grid (LG) assembly, incore monitoring instrumentation (IMI) guide tube 

assembly, and the flow distributor assembly. 

Common miscellaneous material/environment combinations where aging effects are not expected 

to degrade the ability of the structure or component to perform its intended function for the 

subsequent period of extended operation are included in IV.E. 

System Interfaces 

The systems that interface with the reactor vessel internals include the reactor pressure vessel 

(RPV) (IV.A2).

C1. REACTOR COOLANT PRESSURE BOUNDARY (BOILING WATER REACTOR) 

Systems, Structures, and Components

This section addresses the boiling water reactor (BWR) primary coolant pressure boundary and 

consists of the reactor coolant recirculation system and portions of other systems connected to 

the pressure vessel extending to the second containment isolation valve or to the first anchor 

point outside containment. The connected systems include the residual heat removal (RHR), 

low–pressure core spray (LPCS), high–pressure core spray (HPCS), low-pressure coolant 

injection (LPCI) high-pressure coolant injection (HPCI), reactor core isolation cooling (RCIC), 

isolation condenser (IC), reactor water cleanup (RWCU), standby liquid control (SLC) feedwater 

(FW), and main steam (MS) systems; and the steam line to the HPCI and RCIC pump turbines. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all systems, 

structures and components (SSCs) that comprise the reactor coolant pressure boundary (RCPB) 

are governed by Group A Quality Standards. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review. 

Common miscellaneous material/environment combinations where aging effects are not expected 

to degrade the ability of the structure or component to perform its intended function for the 

subsequent period of extended operation are included in IV.E. 

System Interfaces 

The systems that interface with the RCPB include the reactor pressure vessel (IV.A1), the 

emergency core cooling system (V.D2), the SLC system (VII.E2), the RWCU system (VII.E3), the 

shutdown cooling (SDC) system (older plants) (VII.E4), the MS system (VIII.B2), and the 

FW system (VIII.D2).

C2. REACTOR COOLANT SYSTEM AND CONNECTED LINES 

(PRESSURIZED WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the pressurized water reactor (PWR) primary coolant pressure boundary 

and consists of the reactor coolant system (RCS) and portions of other connected systems 

generally extending up to and including the second containment isolation valve or to the first 

anchor point and including the containment isolation valves, the reactor coolant pump (RCP), 

valves, pressurizer, and the pressurizer relief tank. The connected systems include the residual 

heat removal (RHR) or low pressure injection (LPI) system, high pressure injection (HPI) system, 

sampling system, and the small-bore piping. With respect to other systems such as the core flood 

system (CFS) or the safety injection tank (SIT) and the chemical and volume control system 

(CVCS), the isolation valves associated with the boundary between American Society of 

Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) class 1 and 2 are located 

inside the containment. Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications 

and Standards for Water-, Steam-, and Radioactive-Waste-Containing Components of Nuclear 

Power Plants,” and with the exception of the pressurizer relief tank, which is governed by Group B 

Quality Standards, all systems, structures and components (SSCs) that comprise the RCS are 

governed by Group A Quality Standards. The recirculating pump seal water heat exchanger is 

discussed in V.D1. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review. 

Common miscellaneous material/environment combinations where aging effects are not expected 

to degrade the ability of the structure or component to perform its intended function for the 

subsequent period of extended operation are included in IV.E. 

System Interfaces 

The systems that interface with the reactor coolant pressure boundary (RCPB) include the reactor 

pressure vessel (RPV) (IV.A2), the steam generators (SGs) (IV.D1 and IV.D2), the emergency 

core cooling system (ECCS) (V.D1), and the CVCS (VII.E1).

D1. STEAM GENERATOR (RECIRCULATING) 

Systems, Structures, and Components 

This section addresses the recirculating-type steam generators (SGs), as found in Westinghouse 

and Combustion Engineering (CE) pressurized water reactor (PWR), including all internal 

components and water/steam nozzles and safe ends. Based on Regulatory Guide (RG) 1.26, 

“Quality Group Classifications and Standards for Water-, Steam-, and Radioactive-WasteContaining Components of Nuclear Power Plants,” the primary water side (tube side) of the SG is 

governed by Group A Quality Standards, and the secondary water side is governed by Group B 

Quality Standards. 

Common miscellaneous material/environment combinations where aging effects are not expected 

to degrade the ability of the structure or component to perform its intended function for the 

subsequent period of extended operation are included in IV.E. 

System Interfaces 

The systems that interface with the SGs include the reactor coolant system (RCS) and connected 

lines (IV.C2), the containment isolation components (V.C), the main steam (MS) system (VIII.B1), 

the feedwater (FW) system (VIII.D1), the SG blowdown system (VIII.F), and the auxiliary 

feedwater (AFW) system (VIII.G).

E. COMMON MISCELLANEOUS MATERIAL/ENVIRONMENT COMBINATIONS 

Systems, Structures, and Components 

This section addresses the aging management programs (AMPs) for miscellaneous 

material/environment combinations which may be found throughout the reactor vessel, internals 

and reactor coolant systems, structures, and components (SSCs). For the material/environment 

combinations in this part, aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation. With 

the exception of components within the scope of American Society of Mechanical Engineers 

Boiler and Pressure Vessel Code (ASME Code), Section XI or for those where a further 

evaluation results in identifying aging effects and a corresponding AMP, no AMPs for these 

structures and components are required. 

System Interfaces 

The structures and components covered in this section belong to the engineered safety 

features in pressurized water reactors (PWRs) and boiling water reactors (BWRs). (For example, 

see System Interfaces in V.A to V.D2 for details.)

A. CONTAINMENT SPRAY SYSTEM (PRESSURIZED WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the containment spray system for pressurized water reactors (PWRs) 

designed to lower the pressure, temperature, and gaseous radioactivity (iodine) content of the 

containment atmosphere following a design basis event. Spray systems using chemically treated 

borated water are reviewed. The system consists of piping and valves, including containment 

isolation valves, flow elements, orifices, pumps, spray nozzles, eductors, and the containment 

spray system heat exchanger (for some plants). 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all 

components that comprise the containment spray system outside or inside the containment are 

governed by Group B Quality Standards. 

Pumps and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in V.E. Common miscellaneous material/environment 

combinations, where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation, are 

included in V.F. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the containment spray system are the PWR emergency core 

cooling (V.D1), and open- or closed-cycle cooling water (CCCW) systems (VII.C1 or VII.C2).

B. STANDBY GAS TREATMENT SYSTEM (BOILING WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the standby gas treatment system found in boiling water reactors (BWRs) 

and consists of ductwork, filters, and fans. Based on Regulatory Guide (RG) 1.26, “Quality Group 

Classifications and Standards for Water-, Steam-, and Radioactive-Waste-Containing 

Components of Nuclear Power Plants,” all components that comprise the standby gas treatment 

system are governed by Group B Quality Standards. 

Specifically, charcoal absorber filters are to be addressed consistent with the U.S. Nuclear 

Regulatory Commission (NRC) position on consumables, provided in the NRC letter from 

Christopher I. Grimes to Douglas J. Walters of Nuclear Energy Institute (NEI), dated 

March 10, 2000. Components that function as system filters are typically replaced based on 

performance or condition monitoring that identifies whether these components are at the 

end of their qualified lives and may be excluded, from an aging management review (on a 

plant-specific basis), under Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1)(ii). 

As part of the methodology description, the application should identify the standards that are 

relied on for replacement, for example, National Fire Protection Association (NFPA) standards for 

fire protection equipment. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in V.E. Common miscellaneous material/environment 

combinations, where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation, are 

included in V.F. 

System Interfaces 

The systems that potentially interface with the standby gas treatment system include the main 

steam system (boiling water reactor) (VIII.B2) or extraction steam system (VIII. C), as sources of 

steam for the steam jet air ejector outlets from the main condenser.

C. CONTAINMENT ISOLATION COMPONENTS 

Systems, Structures, and Components 

This section addresses the containment isolation components found in all designs of boiling water 

reactors (BWRs) and pressurized water reactors (PWRs) in the United States. The system 

consists of isolation barriers in lines for BWR and PWR nonsafety systems, such as the plant 

heating, waste gas, plant drain, liquid waste, and cooling water systems. Based on Regulatory 

Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, and 

Radioactive-Waste-Containing Components of Nuclear Power Plants,” all components 

that comprise the containment isolation components are governed by Group A or B 

Quality Standards. 

The aging management programs (AMPs) for hatchways, hatch doors, penetration sleeves, 

penetration bellows, seals, gaskets, and anchors are addressed in II.A and II.B. The containment 

isolation valves for in-scope systems are addressed in the appropriate sections in IV, VII, and VIII. 

The AMPs for the degradation of external surfaces of components and miscellaneous bolting are 

included in V.E. Common miscellaneous material/environment combinations, where aging effects 

are not expected to degrade the ability of the structure or component to perform its intended 

function for the subsequent period of extended operation, are included in V.F. 

System Interfaces 

The system interfaces with the containment isolation components addressed in this section are 

addressed in the respective portions of the Generic Aging Lessons Learned for Subsequent 

License Renewal (GALL-SLR) Report associated with the process lines (e.g., closed-cycle cooling 

water) penetrating containment.

D1. EMERGENCY CORE COOLING SYSTEM (PRESSURIZED WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the emergency core cooling systems for pressurized water reactors 

(PWRs) designed to cool the reactor core and provide safe shutdown following a design basis 

accident. The core cooling systems consist of the core flood system (CFS), residual heat removal 

(RHR) (or shutdown cooling), high-pressure safety injection (HPSI), low-pressure safety injection 

(LPSI), and spent fuel pool (SFP) cooling systems, the lines to the chemical and volume control 

system (CVCS), the emergency sump, the HPSI and LPSI pumps, the pump seal coolers, the 

RHR heat exchanger, and the refueling water tank (RWT). 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications, and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all 

components that comprise the emergency core cooling system are governed by Group B Quality 

Standards. Portions of the RHR, HPSI, and LPSI systems and the CVCS extending from the 

reactor coolant system (RCS) up to and including the second containment isolation valve are 

governed by Group A Quality Standards and covered in IV.C2. 

Pumps and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in V.E. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VI.F. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the emergency core cooling system include the RCS and 

connected lines (IV.C2), the containment spray system (V.A), the spent fuel pool (SFP) cooling 

and cleanup system (VII.A3), the closed-cycle cooling water (CCCW) system (VII.C2), the ultimate 

heat sink (UHS) (VII.C3), the CVCS (VII.E1), and the open-cycle cooling water (service water 

system) (VII.C1).

D2. EMERGENCY CORE COOLING SYSTEM (BOILING WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the emergency core cooling systems for boiling water reactors (BWRs) 

designed to cool the reactor core and provide safe shutdown following a design basis accident. 

The cooling systems consist of the high-pressure coolant injection (HPCI), reactor core isolation 

cooling (RCIC), high-pressure core spray (HPCS), automatic depressurization, low-pressure core 

spray (LPCS), low-pressure coolant injection (LPCI), and residual heat removal (RHR) systems, 

including various pumps and valves, the RHR heat exchangers, and the drywell and suppression 

chamber spray system (DSCSS). The auxiliary area ventilation system includes RCIC, HPCI, 

RHR, and core spray pump room cooling. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all 

components that comprise the emergency core cooling system outside the containment are 

governed by Group B Quality Standards and the portion of the DSCSS inside the containment up 

to the isolation valve is governed by Group A Quality Standards. Portions of the HPCI, RCIC, 

HPCS, LPCS, and LPCI (or RHR) systems extending from the reactor vessel up to and including 

the second containment isolation valve are governed by Group A Quality Standards and covered 

in IV.C1. 

Pumps and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The system piping includes all pipe sizes, including instrument piping. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in V.E. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VI.F. 

System Interfaces 

The systems that interface with the emergency core cooling system include the reactor vessel 

(IV.A1), the reactor coolant pressure boundary (RCPB) (IV.C1), the feedwater (FW) system 

(VIII.D2), the condensate system (VIII.E), the closed-cycle cooling water (CCCW) system (VII.C2), 

the open-cycle cooling water (OCCW) system (VII.C1), and the ultimate heat sink (UHS) (VII.C3).

E. EXTERNAL SURFACES OF COMPONENTS AND MISCELLANEOUS BOLTING 

Systems, Structures, and Components 

This section addresses the aging management programs (AMPs) for the degradation of external 

surfaces of structures and components, including closure bolting in the engineered safety features 

in pressurized water reactors (PWRs) and boiling water reactors (BWRs). For the steel 

components in PWRs, this section addresses only boric acid corrosion of external surfaces as a 

result of dripping borated water leaking from an adjacent PWR component. Boric acid corrosion 

can also occur for steel components containing borated water leaking from an adjacent PWR 

component. Boric acid corrosion can also occur for steel components containing borated water 

due to leakage, such components and the related AMP are covered in the appropriate major plant 

sections in V. 

System Interfaces 

The structures and components covered in this section belong to the engineered safety features 

in PWRs and BWRs. (For example, see System Interfaces in V.A to V.D2 for details.)

F. COMMON MISCELLANEOUS MATERIAL/ENVIRONMENT COMBINATIONS 

Systems, Structures, and Components 

This section addresses the aging management programs (AMPs) for miscellaneous 

material/environment combinations which may be found throughout the emergency safety feature 

system’s structures and components (SCs). For the material/environment combinations in this 

part, aging effects are not expected to degrade the ability of the structure or component to perform 

its intended function for the subsequent period of extended operation. With the exception of 

components within the scope of American Society of Mechanical Engineers Boiler and Pressure 

Vessel Code (ASME Code), Section XI or for those where a further evaluation results in 

identifying aging effects and a corresponding AMP, no AMPs for these SCs are required. 

System Interfaces 

The SCs covered in this section belong to the engineered safety features in pressurized water 

reactors (PWRs) and boiling water reactor (BWRs). (For example, see System Interfaces in V.A 

to V.D2 for details.)

A. EQUIPMENT NOT SUBJECT TO 10 CFR 50.49 ENVIRONMENTAL 

QUALIFICATION REQUIREMENTS 

Systems, Structures, and Components 

This section addresses electrical cables and connections that are not subject to the environmental 

qualification (EQ) requirements of Title 10 of the Code of Federal Regulations (10 CFR) 50.49 and 

that are installed in power and instrumentation and control (I&C) applications. The power, control 

and instrumentation cables and connections addressed are low-voltage [i.e., typical operating 

voltage of less than 1,000 volt–but no greater than 2 kilovolts (kV) and medium-voltage (2 kV to 

35 kV)]. High-voltage (>35 kV) power cables and connections have unique, specialized 

constructions and must be evaluated on a plant-specific basis. 

This section also addresses components that are relied upon to meet the station blackout (SBO) 

requirements for restoration of offsite power. The offsite power system relied upon in the 

plant-specific current licensing basis (CLB) for compliance with 10 CFR 50.63, that connects the 

plant to the offsite power source, is included in the SBO restoration equipment scope. The 

electrical distribution equipment out to the first circuit breaker with the offsite distribution system 

(i.e., equipment in the switchyard) is included within the SBO restoration equipment scope of 

license renewal. This path typically includes the circuit breakers that connect to the offsite system 

power transformers (startup transformers), the transformers themselves, the intervening overhead 

or underground circuits between the circuit breaker and transformer and the transformer onsite 

electrical distribution system, and the associated control circuits and structures. However, the 

staff's review is based on the plant-specific CLB, regulatory requirements, and offsite power 

design configurations. 

Electrical cables and their required terminations (i.e., connections) are typically reviewed as a 

single commodity. The types of connections included in this review are splices, mechanical 

connectors, fuse holders, and terminal blocks. This common review is translated into program 

actions, which treat cables and connections in the same manner. 

Electrical cables and connections that are in the plant’s EQ program are addressed in VI.B. 

System Interfaces 

Electrical cables and connections functionally interface with all plant systems that rely on electric 

power or I&C. Electrical cables and connections also interface with and are supported by 

structural commodities (e.g., cable trays, conduit, cable trenches, cable troughs, duct banks, cable 

vaults, and manholes) that are reviewed, as appropriate, in the systems, structures, and 

components (SSCs) section.

B. EQUIPMENT SUBJECT TO 10 CFR 50.49 ENVIRONMENTAL 

QUALIFICATION REQUIREMENTS 

Systems, Structures, and Components 

The U.S. Nuclear Regulatory Commission (NRC) has established nuclear station environmental 

qualification (EQ) requirements in Title 10 of the Code of Federal Regulations (10 CFR) Part 50 

Appendix A, Criterion 4, and in 10 CFR 50.49. As required by 10 CFR 50.49, an EQ program 

is established to demonstrate that certain electrical components located in harsh plant 

environments (i.e., those areas of the plant that could be subject to the harsh environmental 

effects of a loss of coolant accident (LOCA), high-energy line breaks (HELBs) or post-LOCA 

radiation) are qualified to perform their safety function in those harsh environments after the 

effects of inservice aging. As required by 10 CFR 50.49, the effects of significant aging 

mechanisms are addressed as part of EQ. Components in the EQ program have a qualified life, 

and the components are replaced at the end of that qualified life if it is shorter than the current 

operating term. The qualified life may be extended by methods such as refurbishment, reanalysis, 

or through ongoing qualification but the licensee is required by the EQ regulation (10 CFR 50.49) 

to replace the component when its qualified life has expired. 

Similarly, some nuclear power plants have mechanical equipment that was qualified in 

accordance with the provisions of Criterion 4 of Appendix A to 10 CFR Part 50. 

System Interfaces 

Equipment subject to 10 CFR 50.49 EQ requirements could functionally interface with all plant 

systems that rely on electric power or instrumentation and control (I&C).

Systems, Structures, and Components 

This section discusses those structures and components used for new fuel storage which include 

carbon steel new fuel storage racks located in the auxiliary building or the fuel handling building. 

The racks are exposed to the temperature and humidity in the auxiliary building. The racks are 

generally painted with a protective coating. Based on Regulatory Guide (RG) 1.26, “Quality 

Group Classifications and Standards for Water-, Steam-, and Radioactive-Waste-Containing 

Components of Nuclear Power Plants,” all components used for new fuel storage are governed by 

Group C Quality Standards. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or

A2. SPENT FUEL STORAGE 

Systems, Structures, and Components 

This section discusses those structures and components used for spent fuel storage and includes 

stainless steel (SS) spent fuel storage racks (typically made of stainless steel) and neutronabsorbing materials (e.g., Boraflex, Boral®, or boron-steel sheets, if used) submerged in 

chemically treated oxygenated boiling water reactor (BWR) or borated pressurized water reactor 

(PWR) water. The intended function of a spent fuel rack is to separate spent fuel assemblies. 

Neutron absorber sheets fastened to the storage cells provide for neutron absorption and help 

maintain subcriticality of spent fuel assemblies in the spent fuel pool (SFP). 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all 

components used for spent fuel storage are governed by Group C Quality Standards. In some 

plants, the Boraflex has been replaced by metallic-based absorber materials. 

The aging management programs (AMPs) for the degradation of external surfaces of components

A3. SPENT FUEL POOL COOLING AND CLEANUP 

(PRESSURIZED WATER REACTOR) 

Systems, Structures, and Components 

This section discusses the pressurized water reactor (PWR) spent fuel pool (SFP) cooling and 

cleanup system and consists of piping, valves, heat exchangers, filters, linings, demineralizers, 

and pumps. The system contains borated water. The system removes heat from the SFP and 

transfers heat to the open-cycle cooling water (OCCW) system, which in turn transfers heat to the 

OCCW system. Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and 

Standards for Water-, Steam-, and Radioactive-Waste-Containing Components of Nuclear Power 

Plants,” all components that comprise the PWR SFP cooling and cleanup system are governed by 

Group C Quality Standards. 

With respect to filters, these items are to be addressed consistent with the U.S. Nuclear 

Regulatory Commission (NRC) position on consumables, provided in the NRC letter 

from Christopher I. Grimes to Douglas J. Walters of the Nuclear Energy Institute (NEI), dated 

March 10, 2000. Specifically, components that function as system filters are typically replaced 

based on performance or condition monitoring that identifies whether these components are at the 

end of their qualified lives and may be excluded, on a plant-specific basis, from an 

aging management review (AMR) under Title 10 of the Code of Federal Regulations 

(10 CFR) 54.21(a)(1)(ii). As part of the methodology description, the application should identify 

the standards that are relied on for replacement, for example, National Fire Protection Association 

(NFPA) standards for fire protection equipment. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to 10 CFR 54.21(a)(1), therefore, they are not subject to an AMR. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the PWR spent fuel cooling and cleanup system are the PWR 

emergency core cooling system (V.D1), the closed-cycle cooling water (CCCW) system (VII.C2), 

and the PWR chemical and volume control system (CVCS) (VII.E1).

A4. SPENT FUEL POOL COOLING AND CLEANUP (BOILING WATER REACTOR) 

Systems, Structures, and Components 

This section discusses the boiling water reactor (BWR) spent fuel pool (SFP) cooling and cleanup

system and consists of piping, valves, heat exchangers, filters, linings, demineralizers, and 

pumps. The system contains chemically treated oxygenated water. The system removes heat 

from the SFP and transfers the heat to the closed-cycle cooling water (CCCW) system, which in 

turn transfers the heat to the open-cycle cooling water (OCCW) system. Based on Regulatory 

Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, and 

Radioactive-Waste-Containing Components of Nuclear Power Plants,” all components 

that comprise the BWR SFP cooling and cleanup system are governed by Group C 

Quality Standards. 

With respect to filters, these items are to be addressed consistent with the U.S. Nuclear 

Regulatory Commission (NRC) position on consumables, provided in the NRC letter 

from Christopher I. Grimes to Douglas J. Walters of the Nuclear Energy Institute (NEI), dated 

March 10, 2000. Specifically, components that function as system filters are typically replaced 

based on performance or condition monitoring that identifies whether these components are

(10 CFR ) 54.21(a)(1)(ii). As part of the methodology description, the application should identify 

the standards that are relied on for replacement, for example, National Fire Protection Association 

(NFPA) standards for fire protection equipment. 

Pump and valve internals perform their intended functions with moving parts or with a change in

A5. SUPPRESSION POOL CLEANUP SYSTEM (BOILING WATER REACTOR) 

Systems, Structures, and Components 

This section discusses the suppression pool cleanup system, which maintains water quality in the 

suppression pool in boiling water reactors (BWRs). The components of this system include 

piping, filters, valves, and pumps. These components are fabricated of carbon, low-alloy, or 

austenitic stainless steel (SS). Based on Regulatory Guide (RG) 1.26, “Quality Group 

Classifications and Standards for Water-, Steam-, and Radioactive-Waste-Containing 

Components of Nuclear Power Plants,” the components that comprise the suppression pool 

cleanup system are governed by the same Group C Quality Standards Group as the 

corresponding components in the spent fuel pool (SFP) cooling and cleanup system (VII.A4). 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The system that interfaces with the suppression pool cleanup system is the boiling water reactor 

(BWR) containments (II.B), or BWR emergency core cooling system (V.D2). 

Evaluation Summary 

There are no tables associated with this section because the suppression pool cleanup system in 

BWRs is similar to the SFP cooling and cleanup system (VII.A4), and the components in the two 

systems are identical or very similar. Therefore, the reader is referred to the section for the spent 

fuel storage pool system for a listing of aging effects, aging mechanisms, and AMPs that are to be 

applied to the suppression pool cleanup system components. [The only component in VII.A4 that 

may not be applicable to the suppression pool cleanup system is the heat exchanger (AMR 

line-items VII.A4.AP-111, VII.A4.4AP-139, VII.A4.AP-189)].

B. OVERHEAD HEAVY LOAD AND LIGHT LOAD (RELATED TO REFUELING) 

HANDLING SYSTEMS 

Systems, Structures, and Components 

Most commercial nuclear facilities have between 50 and 100 cranes. Many of these cranes are 

industrial grade cranes that must meet the requirements of Title 29 of the Code of Federal 

Regulations (29 CFR) Volume XVII, Part 1910, and Section 1910.179. They do not fall within the 

scope of 10 CFR Part 54.4 and therefore are not required to be part of the integrated plant 

assessment. Normally fewer than 10 cranes fall within the scope of 10 CFR Part 54.4. These 

cranes must comply with the requirements provided in 10 CFR Part 50.65 and Regulatory 

Guide (RG) 1.160 for monitoring the effectiveness of maintenance at nuclear power plants. 

The Inspection of Overhead Heavy Load and Light Load (Related to Refueling) Handling Systems 

(the Program) must demonstrate that the testing and the monitoring of the maintenance programs 

have been completed to ensure that the structures, systems, and components of these cranes are 

capable of sustaining their rated loads during the period of extended operation. It should be noted 

that many of the structures and components of these cranes can be classified as moving parts or 

as components which change configuration or they may be subject to replacement based on a 

qualified life. In any of these cases, they will not fall within the scope of this aging management 

review (AMR). The primary components that this program is concerned with are the structural 

girders and beams that make up the bridge and the trolley.

C1. OPEN-CYCLE COOLING WATER SYSTEM (SERVICE WATER SYSTEM) 

Systems, Structures, and Components

This section discusses the open-cycle cooling water (OCCW) (or service water) system, which 

consists of piping, heat exchangers, pumps, flow orifices, basket strainers, and valves, including 

containment isolation valves. Because the characteristics of an OCCW system may be unique 

to each facility, the OCCW system is defined as a system or systems that transfer heat from 

safety-related systems, structures and components (SSCs) to the ultimate heat sink (UHS), such 

as a lake, ocean, river, spray pond, or cooling tower. The aging management programs (AMPs) 

described in this section apply to any such system, provided the service conditions and materials 

of construction are identical to those identified in the section. The system removes heat from the 

closed-cycle cooling water (CCCW) system, and, in some plants, other auxiliary systems and 

components, such as steam turbine bearing oil coolers or miscellaneous coolers in the 

condensate system. The only heat exchangers addressed in this section are those removing heat 

from the CCCW system. Heat exchangers for removing heat from other auxiliary systems and 

components are addressed in their respective systems, such as those for the steam turbine 

bearing oil coolers (VIII.A) and for the condensate system coolers (VIII.E). 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all 

components that comprise the OCCW system are governed by Group C Quality Standards, with 

the exception of those forming part of the containment penetration boundary which are governed 

by Group B Quality Standards. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

AMPs for the degradation of external surfaces of components and miscellaneous bolting are 

included in VII.I. Common miscellaneous material/environment combinations where aging effects 

are not expected to degrade the ability of the structure or component to perform its intended 

function for the subsequent period of extended operation are included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that may interface with the OCCW system include the CCCW system (VII.C2), the 

ultimate heat sink (UHS) (VII.C3), the emergency diesel generator (EDG) system (VII.H2), the 

containment spray system (V.A), the [pressurized water reactor (PWR)] steam generator (SG) 

blowdown system (VIII.F), the condensate system (VIII.E), the auxiliary feedwater (AFW) system 

(PWR) (VIII.G), the emergency core cooling system (PWR) (V.D1), and the emergency core 

cooling system boiling water reactor (BWR) (V.D2).

C2. CLOSED-CYCLE COOLING WATER SYSTEM 

Systems, Structures, and Components 

This section discusses the closed-cycle cooling water (CCCW) system, which consists of piping, 

radiation elements, temperature elements, heat exchangers, pumps, tanks, flow orifices, and 

valves, including containment isolation valves. The system contains chemically treated 

demineralized water. The CCCW system is designed to remove heat from various auxiliary 

structures and components such as the chemical and volume control system (CVCS) and the 

spent fuel cooling system to the open-cycle cooling water (OCCW) system (VII.C1). A CCCW 

system is defined as part of the service water system that does not reject heat directly to a heat 

sink, has water chemistry control, and is not subject to significant sources of contamination. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all 

components in the CCCW system are classified as Group C Quality Standards, with the exception 

of those forming part of the containment penetration boundary, which are Group B. 

The aging management programs (AMPs) for the heat exchanger between the CCCW and the 

OCCW systems are addressed in the OCCW (VII.C1). The AMPs for the heat exchangers 

between the CCCW system and the interfacing auxiliary systems are included in the evaluations 

of their respective systems, such as those for the pressurized water reactor (PWR) and boiling 

water reactor (BWR) spent fuel pool (SFP) cooling and cleanup systems (VII.A3 and VII.A4, 

respectively) and the PWR CVCS (VII.E1). 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

AMPs for the degradation of external surfaces of components and miscellaneous bolting are 

included in VII.I. Common miscellaneous material/environment combinations where aging effects 

are not expected to degrade the ability of the structure or component to perform its intended 

function for the subsequent period of extended operation are included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the CCCW system include the OCCW system (VII.C1), the PWR 

SFP cooling and cleanup system (VII.A3), the BWR SFP cooling and cleanup system (VII.A4), the 

PWR CVCS (VII.E1), the BWR reactor water cleanup (RWCU) system (VII.E3), the shutdown 

cooling (SDC) system (older BWR, VII.E4), the primary containment heating and ventilation 

system (VII.F3), fire protection (VII.G), the emergency diesel generator (EDG) system (VII.H2), 

the PWR containment spray system (V.A), the PWR and BWR emergency core cooling systems 

(V.D1 and V.D2), the PWR steam generator (SG) blowdown system (VIII.F), the condensate 

system (VIII.E), and the PWR auxiliary feedwater (AFW) system (VIII.G).

C3. ULTIMATE HEAT SINK 

Systems, Structures, and Components 

The ultimate heat sink (UHS) consists of a lake, ocean, river, spray pond, or cooling tower. The 

UHS provides sufficient cooling water for safe reactor shutdown and reactor cooldown via the 

residual heat removal (RHR) system or other similar system. Due to the varying configurations of 

connections to lakes, oceans, and rivers, a plant-specific aging management program (AMP) is 

required. Appropriate AMPs shall be provided to trend and project (i) deterioration of earthen 

dams and impoundments; (ii) rate of silt deposition; (iii) meteorological, climatological, and 

oceanic data since obtaining the Final Safety Analysis Report (FSAR) data; (iv) water level 

extremes for plants located on rivers; and (v) aging degradation of all upstream and downstream 

dams affecting the UHS. 

The systems, structures, and components (SSCs) included in this section consist of piping, 

valves, and pumps. The cooling tower is addressed in this report on water-control structures 

(III.A6). The UHS absorbs heat from the RHR system or other similar system. Based on 

Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, 

and Radioactive-Waste-Containing Components of Nuclear Power Plants,” the piping and valves 

used for the UHS are governed by Group C Quality Standards. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The AMPs for the degradation of external surfaces of components and miscellaneous bolting are 

included in VII.I. Common miscellaneous material/environment combinations where aging effects 

are not expected to degrade the ability of the structure or component to perform its intended 

function for the subsequent period of extended operation are included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the UHS include the open-cycle cooling water (OCCW) system 

(VII.C1) and the pressurized water reactor (PWR) and boiling water reactor (BWR) emergency 

core cooling systems (V.D1 and V.D2).

D. COMPRESSED AIR SYSTEM 

Systems, Structures, and Components 

This section discusses the compressed air system, which consists of piping, valves (including 

containment isolation valves), air receivers, pressure regulators, filters, and dryers. The system 

components and piping are located in various buildings at most nuclear power plant. Based on 

Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, 

and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all components of the 

compressed air system are classified as Group D Quality Standards, with the exception of those 

forming part of the containment penetration boundary, which are Group B. However, the 

cleanliness of these components and high air quality is to be maintained because the air provides 

the motive power for instruments and active components (some of them safety-related) that may 

not function properly if nonsafety Group D equipment is contaminated. 

With respect to filters, these items are to be addressed consistent with the U.S. Nuclear 

Regulatory Commission (NRC) position on consumables, provided in the NRC letter from 

Christopher I. Grimes to Douglas J. Walters of the Nuclear Energy Institute, dated 

March 10, 2000. Specifically, components that function as system filters are typically replaced 

based on performance or condition monitoring that identifies whether these components are 

at the end of their qualified lives and may be excluded, on a plant-specific basis, from an 

aging management review (AMR) under Title 10 of the Code of Federal Regulations 

(10 CFR) 54.21(a)(1)(ii). As part of the methodology description, the application should identify 

the standards that are relied on for replacement, for example, National Fire Protection Association 

(NFPA) standards for fire protection equipment. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to 10 CFR 54.21(a)(1), therefore, they are not subject to an AMR. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

Various other systems discussed in this report may interface with the compressed air system.

E1. CHEMICAL AND VOLUME CONTROL SYSTEM 

(PRESSURIZED WATER REACTOR) 

Systems, Structures, and Components 

This section discusses a portion of the pressurized water reactor (PWR) chemical and volume 

control system (CVCS). The portion of the PWR CVCS covered in this section extends from the 

isolation valves associated with the reactor coolant pressure boundary (RCPB) (and Code change 

as discussed below) to the volume control tank. This portion of the PWR CVCS consists of 

high- and low-pressure piping and valves (including the containment isolation valves), 

regenerative and letdown heat exchangers, pumps, basket strainers, and the volume control tank. 

The system contains chemically treated borated water; the shell side of the letdown heat 

exchanger contains closed-cycle cooling water (CCCW) (treated water). 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all 

components that comprise the CVCS are governed by Group C Quality Standards. Portions of 

the CVCS extending from the reactor coolant system (RCS) up to and including the isolation 

valves associated with RCPB are governed by Group A Quality Standards and covered in IV.C2. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the CVCS include the RCS (IV.C2), the emergency core 

cooling system (V.D1), the spent fuel pool (SFP) cooling system (VII.A3), and the CCCW 

system (VII.C2).

E2. STANDBY LIQUID CONTROL SYSTEM 

(BOILING WATER REACTOR) 

Systems, Structures, and Components 

This section discusses the portion of the standby liquid control (SLC) system extending from the 

containment isolation valve to the solution storage tank. The system serves as a backup reactivity 

control system in all boiling water reactors (BWRs). The major components of this system are the 

piping, the solution storage tank, the solution storage tank heaters, valves, and pumps. All of the 

components from the storage tank to the explosive actuated discharge valve operate in contact 

with a sodium pentaborate (Na2B10O16•10H2O) solution. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all 

components that comprise the SLC system are governed by Group B Quality Standards. The 

portions of the SLC system extending from the reactor coolant pressure boundary (RCPB) up to 

and including the containment isolation valves are governed by Group A Quality Standards and 

are covered in IV.C1. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The system that interfaces with the SLC system is the BWR reactor pressure vessel (IV.A1). If 

used, the SLC system would inject sodium pentaborate solution into the pressure vessel near the 

bottom of the reactor core.

E3. REACTOR WATER CLEANUP SYSTEM 

(BOILING WATER REACTOR) 

Systems, Structures, and Components 

This section discusses the reactor water cleanup (RWCU) system, which provides for cleanup 

and particulate removal from the recirculating reactor coolant in all boiling water reactors (BWRs). 

Some plants may not include the RWCU system in the scope of license renewal, while other 

plants may include the RWCU system because it is associated with safety-related functions. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” the portion of 

the RWCU system extending from the reactor coolant recirculation system up to and including the 

containment isolation valves are covered in IV.C1. The remainder of the system outboard of the 

isolation valves is governed by Group C Quality Standards. In this table, only aging management 

programs (AMPs) for RWCU-related piping and components outboard of the isolation valves are 

evaluated. The AMP for containment isolation valves in the RWCU system is evaluated in IV.C1, 

which concerns the reactor coolant pressure boundary (RCPB) in BWRs. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The AMPs for the degradation of external surfaces of components and miscellaneous bolting are 

included in VII.I. Common miscellaneous material/environment combinations where aging effects 

are not expected to degrade the ability of the structure or component to perform its intended 

function for the subsequent period of extended operation are included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the BWR RWCU system include the RCPB (IV.C1), the 

closed-cycle cooling water (CCCW) system (VII.C2), and the condensate system (VIII.E).

E4. SHUTDOWN COOLING SYSTEM 

(OLDER BOILING WATER REACTOR) 

Systems, Structures, and Components 

This section discusses the shutdown cooling (SDC) system for older vintage boiling water 

reactors (BWRs) and consists of piping and fittings, the SDC system pump, the heat exchanger, 

and valves. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all 

components that comprise the SDC system are governed by Group B Quality Standards. 

Portions of the SDC system extending from the reactor coolant pressure boundary (RCPB) up to 

and including the containment isolation valves are governed by Group A Quality Standards and 

are covered in IV.C1. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the SDC system include the reactor coolant pressure boundary 

(RCPB) (IV.C1) and the closed-cycle cooling water (CCCW) system (VII.C2).

E5. WASTE WATER SYSTEMS 

Systems, Structures, and Components 

This section discusses liquid waste systems such as liquid radioactive waste systems, oily waste 

systems, floor drainage systems, chemical waste water systems, and secondary waste water 

systems. Plants may include portions of waste water systems within the scope of license renewal 

based on the criterion of Title 10 of the Code of Federal Regulations (10 CFR) 54.4.(a)(2). 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” radioactivewaste-containing portions of waste water systems are classified as Group C Quality Standards, 

with the exception of those forming part of the containment pressure boundary, which is classified 

as Group B. Waste water systems that do not contain radioactive waste or form a part of the 

containment pressure boundary are classified as Group D. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to 10 CFR 54.21(a)(1), therefore, they are not subject to an aging 

management review (AMR). 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

Various other systems discussed in this report may interface with waste water systems.

F1. CONTROL ROOM AREA VENTILATION SYSTEM 

Systems, Structures, and Components 

This section discusses the control room area ventilation system (with warm moist air as the 

normal environment), which contains ducts, piping and fittings, equipment frames and housings, 

flexible collars and seals, filters, and heating and cooling air handlers. Based on Regulatory 

Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, and 

Radioactive-Waste-Containing Components of Nuclear Power Plants,” all components that 

comprise the control room area ventilation system are governed by Group B Quality Standards. 

With respect to filters and seals, these items are to be addressed consistent with the U.S. Nuclear 

Regulatory Commission (NRC) position on consumables, provided in the NRC letter from 

Christopher I. Grimes to Douglas J. Walters of the Nuclear Energy Institute, dated 

March 10, 2000. Specifically, components that function as system filters and seals are typically 

replaced based on performance or condition monitoring that identifies whether these components 

are at the end of their qualified lives and may be excluded, on a plant-specific basis, from 

an aging management review (AMR) under Title 10 of the Code of Federal Regulations 

(10 CFR) 54.21(a)(1)(ii). As part of the methodology description, the application should identify 

the standards that are relied on for replacement, for example, National Fire Protection Association 

(NFPA) standards for fire protection equipment. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The system that interfaces with the control room area ventilation system is the auxiliary and 

radwaste area ventilation system (VII.F2). The heat exchanger coils receive their water from 

other systems, such as the hot water heating system or the chilled water cooling system.

Systems, Structures, and Components 

This section discusses the auxiliary and radwaste area ventilation systems (with warm moist air as 

the normal environment) and contains ducts, piping and fittings, equipment frames and housings, 

flexible collars and seals, filters, and heating and cooling air handlers. Based on Regulatory 

Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, and 

Radioactive-Waste-Containing Components of Nuclear Power Plants,” all components 

that comprise the auxiliary and radwaste area ventilation system are governed by Group B 

Quality Standards. 

With respect to filters and seals, these items are to be addressed consistent with the 

U.S. Nuclear Regulatory Commission (NRC) position on consumables, provided in the NRC letter 

from Christopher I. Grimes to Douglas J. Walters of the Nuclear Energy Institute, dated 

March 10, 2000. Specifically, components that function as system filters and seals are typically 

replaced based on performance or condition monitoring that identifies whether these components 

are at the end of their qualified lives and may be excluded, on a plant-specific basis, from 

an aging management review (AMR) under Title 10 of the Code of Federal Regulations 

(10 CFR) 54.21(a)(1)(ii). As part of the methodology description, the application should identify 

the standards that are relied on for replacement, for example, National Fire Protection Association 

(NFPA) standards for fire protection equipment. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the auxiliary and radwaste area ventilation system are the control 

room area ventilation system (VII.F1) and the diesel generator building ventilation system (VII.F4). 

The heat exchanger coils receive their water from other systems, such as the hot water heating 

system or the chilled water cooling system.

F3. PRIMARY CONTAINMENT HEATING AND VENTILATION SYSTEM 

Systems, Structures, and Components 

This section discusses the primary containment heating and ventilation system (with warm moist 

air as the normal environment), which contains ducts, piping and fittings, equipment frames and 

housings, flexible collars and seals, filters, and heating and cooling air handlers. Based on 

Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, 

and Radioactive-Waste-Containing Components of Nuclear Power Plants,” all components that 

comprise the primary containment heating and ventilation system are governed by Group C 

Quality Standards. 

With respect to filters and seals, these items are to be addressed consistent with the 

U.S. Nuclear Regulatory Commission (NRC) position on consumables, provided in the NRC 

letter from Christopher I. Grimes to Douglas J. Walters of the Nuclear Energy Institute, dated 

March 10, 2000. Specifically, components that function as system filters and seals are typically 

replaced based on performance or condition monitoring that identifies whether these components 

are at the end of their qualified lives and may be excluded, on a plant-specific basis, from 

an aging management review (AMR) under Title 10 of the Code of Federal Regulations 

(10 CFR) 54.21(a)(1)(ii). As part of the methodology description, the application should identify 

the standards that are relied on for replacement, for example, National Fire Protection Association 

(NFPA) standards for fire protection equipment. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the primary containment heating and ventilation system are the 

closed-cycle cooling water (CCCW) system (VII.C2) and the pressurized water reactor (PWR) and 

boiling water reactor (BWR) containments (II.A and II.B, respectively). The heat exchanger coils 

receive their water from other systems, such as the hot water heating system or the chilled water 

cooling system.

F4. DIESEL GENERATOR BUILDING VENTILATION SYSTEM 

Systems, Structures, and Components 

This section discusses the diesel generator building ventilation system (with warm moist air as the 

normal environment), which contains ducts, piping and fittings, equipment frames and housings, 

flexible collars and seals, and heating and cooling air handlers. Based on Regulatory Guide 

(RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, and RadioactiveWaste-Containing Components of Nuclear Power Plants,” all components that comprise the diesel 

generator building ventilation system are governed by Group C Quality Standards. 

With respect to filters and seals, these items are to be addressed consistent with the 

U.S. Nuclear Regulatory Commission (NRC) position on consumables, provided in the NRC 

letter from Christopher I. Grimes to Douglas J. Walters of the Nuclear Energy Institute, dated 

March 10, 2000. Specifically, components that function as system seals are typically replaced 

based on performance or condition monitoring that identifies whether these components are 

at the end of their qualified lives and may be excluded, on a plant-specific basis, from an 

aging management review (AMR) under Title 10 of the Code of Federal Regulations 

(10 CFR) 54.21(a)(1)(ii). As part of the methodology description, the application should identify 

the standards that are relied on for replacement, for example, National Fire Protection Association 

(NFPA) standards for fire protection equipment. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The system that interfaces with the diesel generator building system is the auxiliary and radwaste 

area ventilation system (VII.F2). The heat exchanger coils receive their water from other systems, 

such as the hot water heating system or the chilled water cooling system.

G. FIRE PROTECTION 

Systems, Structures, and Components 

This section discusses the fire protection systems for both boiling water reactors (BWRs) and 

pressurized water reactors (PWRs), which consist of several Class 1 structures, mechanical 

systems, and electrical components. The Class 1 structures include the intake structure, the 

turbine building, the reactor building, the auxiliary building, the diesel generator building, and the 

primary containment. Structural assemblies and components include: (i) fire barrier walls, 

(ii) ceilings, (iii) floors, (iv) fire doors, (v) fire barrier penetration seals, (vi) fire dampers, and 

(vii) fire resistant material (structural steel coating and insulation). Mechanical systems include 

the high pressure (HP) service water system, water-based fire suppression systems and gaseous, 

clean agent, and foam extinguishing systems, the reactor coolant pump (RCP) oil collection 

system, and the diesel engine for the diesel fire pump. Mechanical components include; 

(i) buried underground, and aboveground piping and piping components, (ii) filters, (iii) fire 

hydrants, (iv) mulsifiers, (v) fire pumps, (vi) sprinklers/spray nozzles, (vii) strainers, (viii) valves 

(including containment isolation valves), (ix) standpipe, and hose stations, (x) tanks, (xi) drains, 

and (xi) electric raceway fire barriers, [i.e., fire wraps (electric raceway fire barriers are 

non-structural fire-rated assemblies that protect the electrical components and cables 

they enclose)]. 

The fire protection licensing and design basis under subsequent license renewal should not 

reduce requirements in existing approved fire protection programs. However, the Fire Protection 

and Fire Water System programs could include additional tests and inspections during the 

subsequent period of extended operation beyond that in approved fire protection programs. The 

scope of systems, structures, and components (SSCs) included in the Fire Protection and Fire 

Water System programs should consider interfaces between rooms containing safety related and 

nonsafety related SSCs. For example, a nonsafety related damper may have a function to close 

to prevent fire propagation into a room containing safety related SSCs. 

With respect to filters, seals, portable fire extinguishers, and fire hoses, these items are to be 

addressed consistent with the U.S. Nuclear Regulatory Commission (NRC) position on 

consumables, provided in the NRC letter from Christopher I. Grimes to Douglas J. Walters of the 

Nuclear Energy Institute, dated March 10, 2000. Specifically, components that function as 

system filters, seals, portable fire extinguishers, and fire hoses are typically replaced based on 

performance or condition monitoring that identifies whether these components are at the end of 

their qualified lives and may be excluded, on a plant-specific basis, from an aging management 

review (AMR) under Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1)(ii). As part 

of the methodology description, the application should identify the standards that are relied on for 

replacement, for example, National Fire Protection Association (NFPA) codes and standards for 

fire protection equipment. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to 10 CFR 54.21(a)(1), therefore, they are not subject to an AMR. Pump 

and valve casings are passive and long-lived, and therefore would be subject to an AMR. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 
VII G-2 

The system piping includes all pipe sizes, including instrument piping and tubing.

System Interfaces 

The systems and structures that interface with the fire protection system include various Class 1 

structures and component supports (III.A and III.B), the electrical components (VI.A and VI.B), the 

open-cycle cooling water system (service water system) (VII.C1),the closed-cycle cooling water 

system (VII.C2), the compressed air system (VII.D), ventilation systems (VII.F1 – VII.F4), and the 

diesel fuel oil system (VII.H1).

H1. DIESEL FUEL OIL SYSTEM 

Systems, Structures, and Components 

This section discusses the diesel fuel oil system, which consists of aboveground and underground 

piping, valves, pumps, and tanks. Based on Regulatory Guide (RG) 1.26, “Quality Group 

Classifications and Standards for Water-, Steam-, and Radioactive-Waste-Containing 

Components of Nuclear Power Plants,” all components that comprise the diesel fuel oil system 

are governed by Group C Quality Standards. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the diesel fuel oil system are the fire protection (VII.G) and 

emergency diesel generator (EDG) systems (VII.H2).

H2. EMERGENCY DIESEL GENERATOR SYSTEM 

Systems, Structures, and Components 

This section discusses the emergency diesel generator (EDG) system, which contains piping, 

valves, filters, mufflers, strainers, and tanks. Based on Regulatory Guide (RG) 1.26, “Quality 

Group Classifications and Standards for Water-, Steam-, and Radioactive-Waste-Containing 

Components of Nuclear Power Plants,” all components that comprise the EDG system are 

governed by Group C Quality Standards. 

With respect to filters and seals, these items are to be addressed consistent with the 

U.S. Nuclear Regulatory Commission (NRC) position on consumables, provided in the NRC 

letter from Christopher I. Grimes to Douglas J. Walters of the Nuclear Energy Institute, dated 

March 10, 2000. Specifically, components that function as system filters are typically replaced 

based on performance or condition monitoring that identifies whether these components are 

at the end of their qualified lives and may be excluded, on a plant-specific basis, from an 

aging management review (AMR) under Title 10 of the Code of Federal Regulations 

(10 CFR) 54.21(a)(1)(ii). As part of the methodology description, the application should identify 

the standards that are relied on for replacement, for example, National Fire Protection Association 

(NFPA) standards for fire protection equipment. 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VII.I. Common miscellaneous material/environment 

combinations where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation are 

included in VII.J. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the EDG system include the diesel fuel oil system (VII.H1), the 

closed-cycle cooling water (CCCW) system (VII.C2) and the open-cycle cooling water (OCCW) 

system (VII.C1) for some plants.

I. EXTERNAL SURFACES OF COMPONENTS AND MISCELLANEOUS BOLTING 

Systems, Structures, and Components 

This section addresses the aging management programs (AMPs) for the degradation of external 

surfaces of structures and components, including closure bolting in the auxiliary systems in 

pressurized water reactors (PWRs) and boiling water reactors (BWRs). For the steel components 

in PWRs, this section addresses only boric acid corrosion of external surfaces as a result of 

dripping borated water that is leaking from an adjacent PWR component. Boric acid corrosion can 

also occur for steel components containing borated water due to leakage; such components and 

the related AMP are covered in the appropriate major plant sections in VII. 

System Interfaces 

The structures and components covered in this section belong to the auxiliary systems in PWRs 

and BWRs. (For example, see System Interfaces in VII.A1 to VII.H2 for details.)

J. COMMON MISCELLANEOUS MATERIAL/ENVIRONMENT COMBINATIONS 

Systems, Structures, and Components 

This section addresses the aging management programs (AMPs) for miscellaneous 

material/environment combinations which may be found throughout structures and components 

for auxiliary systems. For the material/environment combinations in this part, aging effects are not 

expected to degrade the ability of the structure or component to perform its intended function for 

the subsequent period of extended operation. With the exception of components within the scope 

of American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code), 

Section XI or for those where a further evaluation results in identifying aging effects and a 

corresponding AMP, no AMPs for these structures and components are required. 

System Interfaces 

The structures and components covered in this section belong to the auxiliary systems in 

pressurized water reactor (PWRs) and boiling water reactors (BWRs). (For example, see System 

Interfaces in VII.A to VII.H2 for details.)

A. STEAM TURBINE SYSTEM 

Systems, Structures, and Components 

This section addresses the piping and fittings in the steam turbine system for both pressurized 

water reactors (PWRs) and boiling water reactors (BWRs) and consists of the lines from the 

high-pressure turbine to the moisture separator/reheater (MSR) and the lines from the MSR to the 

low pressure turbine. Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and 

Standards for Water-, Steam-, and Radioactive-Waste-Containing Components of Nuclear Power 

Plants,” all components that comprise the steam turbine system are governed by Group D 

Quality Standards. 

The steam turbine performs its intended functions with moving parts. Pursuant to Title 10 of the 

Code of Federal Regulations (10 CFR) 54.2(a) (1), therefore, it is not subject to an aging 

management review (AMR). 

The aging management programs (AMPs) for the degradation of external surfaces of components 

and miscellaneous bolting are included in VIII.H. Common miscellaneous material/environment 

combinations, where aging effects are not expected to degrade the ability of the structure or 

component to perform its intended function for the subsequent period of extended operation, are 

included in VIII.I. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the steam turbine system include the PWR and BWR main steam 

(MS) system (VIII.B1 and VIII.B2), the extraction steam system (VIII.C), and the condensate 

system (VIII.E).

B1. MAIN STEAM SYSTEM (PRESSURIZED WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the main steam (MS) system for pressurized water reactors (PWRs). The 

section includes the MS lines from the steam generator (SG) to the steam turbine and the turbine 

bypass lines from the MS lines to the condenser. Also included are the lines to the main 

feedwater (FW) and auxiliary feedwater (AFW) pump turbines, steam drains, and valves, including 

the containment isolation valves on the MS lines and the lines to the AFW pump turbines. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” the portion of 

the MS system extending from the SG up to the second containment isolation valve is governed 

by Group B or C Quality Standards, and all other components that comprise the MS system 

located downstream of these isolation valves are governed by Group D Quality Standards. 

The internals of the valves perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of the external surfaces of 

components and miscellaneous bolting are included in VIII.H. Common miscellaneous 

material/environment combinations, where aging effects are not expected to degrade the ability of 

the structure or component to perform its intended function for the subsequent period of extended 

operation, are included in VIII.I. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems and structures that interface with the MS system include PWR concrete or steel 

containment structures (II.A1 and II.A2), common components (II.A3), the SG (IV.D1 and IV.D2), 

the steam turbine system (VIII.A), the FW system (VIII.D1), the condensate system (VIII.E), and 

the AFW system (VIII.G).

B2. MAIN STEAM SYSTEM 

(BOILING WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the main steam (MS) system for boiling water reactors (BWRs). The 

section includes the MS lines from the outermost containment isolation valve to the steam 

turbines and the turbine bypass lines from the MS lines to the condenser. Also included are 

steam drains, lines to the main feedwater (FW), high-pressure coolant injection (HPCI), and 

reactor core isolation cooling (RCIC) turbines. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” portions of 

the MS system extending from the outermost containment isolation valve up to and including the 

turbine stop and bypass valves, as well as connected piping up to and including the first valve that 

is either normally closed or capable of automatic closure during all modes of normal reactor 

operation, are governed by Group B Quality Standards. The remaining portions of the MS system 

consist of components governed by Group D Quality Standards. For BWRs containing a shutoff 

valve in addition to the two containment isolation valves in the MS line, Group B Quality Standards 

apply only to those portions of the system extending from the outermost containment isolation 

valves up to and including the shutoff valve. The portion of the MS system extending from the 

reactor pressure vessel up to the second isolation valve and including the containment isolation 

valves is governed by Group A Quality Standards, and is covered in IV.C1. 

The internals of the valves perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of the external surfaces of 

components and miscellaneous bolting are included in VIII.H. Common miscellaneous 

material/environment combinations, where aging effects are not expected to degrade the ability of 

the structure or component to perform its intended function for the subsequent period of extended 

operation, are included in VIII.I. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the MS system include the BWR Mark 1, Mark 2, or Mark 3 

containment structures (II.B1, II.B2, and II.B3, respectively) and common components (II.B4), the 

reactor coolant pressure boundary (RCPB) (IV.C1), the steam turbine system (VIII.A), the FW 

system (VIII.D2), and the condensate system (VIII.E).

C. EXTRACTION STEAM SYSTEM 

Systems, Structures, and Components 

This section addresses the extraction steam lines for both pressurized water reactors (PWRs) and 

boiling water reactors (BWRs), which extend from the steam turbine to the feedwater (FW) 

heaters, including the drain lines. Based on Regulatory Guide (RG) 1.26, “Quality Group 

Classifications, and Standards for Water-, Steam-, and Radioactive-Waste-Containing 

Components of Nuclear Power Plants,” all components that comprise the extraction steam system 

are governed by Group D Quality Standards. 

The internals of the valves perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of the external surfaces of

D1. FEEDWATER SYSTEM (PRESSURIZED WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the main feedwater (FW) system for pressurized water reactors (PWRs), 

which extends from the condensate system to the steam generator (SG). It consists of the main 

FW lines, FW pumps, and valves, including the containment isolation valves. Based on 

Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, Steam-, 

and Radioactive-Waste-Containing Components of Nuclear Power Plants,” the portion of the 

FW system extending from the secondary side of the SG up to the second containment isolation 

valve is governed by Group B or C Quality Standards. All other components in the FW system 

located downstream from these isolation valves are governed by Group D Quality Standards. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of the external surfaces of 

components and miscellaneous bolting are included in VIII.H. Common miscellaneous 

material/environment combinations, where aging effects are not expected to degrade the ability of 

the structure or component to perform its intended function for the subsequent period of extended 

operation, are included in VIII.I. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems and structures that interface with the FW system include PWR concrete or steel 

containment structures (II.A1 and II.A2) and common components (II.A3), the SGs (IV.D1 and 

IV.D2), the main steam (MS) system (VIII.B1), the extraction steam system (VIII.C), the 

condensate system (VIII.E), and the auxiliary feedwater (AFW) system (VIII.G).

D2. FEEDWATER SYSTEM 

(BOILING WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the main feedwater (FW) system for boiling water reactors (BWRs), which 

extends from the condensate and condensate booster system to the outermost FW isolation valve 

on the FW lines to the reactor vessel. It consists of the main FW lines, FW pumps, and valves. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” the portions 

of the FW system extending from the outermost containment isolation valves up to and including 

the shutoff valve, or the first valve that is either normally closed or capable of closure during all 

modes of normal reactor operation, are governed by Group B Quality Standards. The remaining 

portions of the FW system consist of components governed by Group D Quality Standards. The 

portion of the FW system extending from the reactor vessel up to the second containment 

isolation valve, including the isolation valves, is governed by Group A Quality Standards and is 

covered in IV.C1. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of the external surfaces of 

components and miscellaneous bolting are included in VIII.H. Common miscellaneous 

material/environment combinations, where aging effects are not expected to degrade the ability of 

the structure or component to perform its intended function for the subsequent period of extended 

operation, are included in VIII.I. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the FW system include the BWR Mark 1, Mark 2, or Mark 3 

containment structures (II.B1, II.B2, and II.B3, respectively) and common components (II.B4), the 

reactor coolant pressure boundary (RCPB) (IV.C1), the main steam (MS) system (VIII.B2), the 

extraction steam system (VIII.C), and the condensate system (VIII.E).

E. CONDENSATE SYSTEM 

Systems, Structures, and Components 

This section addresses the condensate system for both pressurized water reactors (PWRs) and 

boiling water reactors (BWRs), which extend from the condenser hotwells to the suction of 

feedwater (FW) pumps, including condensate and condensate booster pumps, condensate 

coolers, condensate cleanup system, and condensate storage tanks. Based on Regulatory Guide 

(RG) 1.26, “Quality Group Classifications, and Standards for Water-, Steam-, and RadioactiveWaste-Containing Components of Nuclear Power Plants,” all components that comprise the 

condensate system are governed by Group D Quality Standards. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of the external surfaces of 

components and miscellaneous bolting are included in VIII.H. Common miscellaneous 

material/environment combinations, where aging effects are not expected to degrade the ability of 

the structure or component to perform its intended function for the subsequent period of extended 

operation, are included in VIII.I. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the condensate system include the steam turbine system (VIII.A), 

the PWR and BWR main steam (MS) system (VIII.B1 and VIII.B2), the PWR and BWR FW 

system (VIII.D1 and VIII.D2), the auxiliary feedwater (AFW) system (VIII.G, PWR only), the BWR 

reactor water cleanup (RWCU) system (VII.E3), the open- or closed-cycle cooling water (CCCW) 

systems (VII.C1 or VII.C2), and the condensate storage facility.

F. STEAM GENERATOR BLOWDOWN SYSTEM 

(PRESSURIZED WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the steam generator (SG) blowdown system for pressurized water 

reactors (PWRs), which extends from the SG through the blowdown condenser and includes the 

containment isolation valves and small bore piping less than nominal pipe size (NPS) 2 in. 

(including instrumentation lines). 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” the portion of 

the blowdown system extending from the SG up to the isolation valve outside the containment 

and including the isolation valves is governed by Group B or C Quality Standards. The remaining 

portions of the SG blowdown system consist of components governed by Group D Quality 

Standards. 

Pump and valve internals perform their intended functions with moving parts or with a change in 

configuration. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), 

therefore, they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of the external surfaces of 

components and miscellaneous bolting are included in VIII.H. Common miscellaneous 

material/environment combinations, where aging effects are not expected to degrade the ability of 

the structure or component to perform its intended function for the subsequent period of extended 

operation, are included in VIII.I. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the blowdown system include the SG (IV.D1 and IV.D2) and the 

open- or closed-cycle cooling water (CCCW) systems (VII.C1 or VII.C2).

G. AUXILIARY FEEDWATER SYSTEM 

(PRESSURIZED WATER REACTOR) 

Systems, Structures, and Components 

This section addresses the auxiliary feedwater (AFW) system for pressurized water reactors 

(PWRs), which extends from the AFW piping that takes suction from the condensate storage tank 

or backup water supply system to the steam generator (SG) or to the main feedwater (FW) line. 

They consist of AFW piping, AFW pumps, pump turbine oil coolers, and valves, including the 

containment isolation valves. 

Based on Regulatory Guide (RG) 1.26, “Quality Group Classifications and Standards for Water-, 

Steam-, and Radioactive-Waste-Containing Components of Nuclear Power Plants,” portions of 

the AFW system extending from the secondary side of the SG up to the second isolation valve 

and including the containment isolation valves are governed by Group B Quality Standards. In 

addition, portions of the AFW system that are required for their safety functions and that either do 

not operate during any mode of normal reactor operation or cannot be tested adequately are also 

governed by Group B Quality Standards. The remainder of the structures and components 

covered in this section are governed by Group C Quality Standards. 

Pump and valve internals perform their intended functions with moving parts or with a change 

in configuration. They are subject to replacement based on qualified life or a specified time 

period. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 54.21(a)(1), therefore, 

they are not subject to an aging management review (AMR). 

The aging management programs (AMPs) for the degradation of the external surfaces of 

components and miscellaneous bolting are included in VIII.H. Common miscellaneous 

material/environment combinations, where aging effects are not expected to degrade the ability of 

the structure or component to perform its intended function for the subsequent period of extended 

operation, are included in VIII.I. 

The system piping includes all pipe sizes, including instrument piping. 

System Interfaces 

The systems that interface with the AFW system include the SG (IV.D1 and IV.D2), the main 

steam (MS) system (VIII.B1), the PWR FW system (VIII.D1), the condensate system (VIII.E), the 

open- or closed-cycle cooling water (CCCW) systems (VII.C1 or VII.C2) and the condensate 

storage facility.

H. EXTERNAL SURFACES OF COMPONENTS AND MISCELLANEOUS BOLTING 

Systems, Structures, and Components 

This section includes the aging management programs (AMPs) for the degradation of external 

surfaces of structures and components, including closure bolting in the steam and power 

conversion systems in pressurized water reactors (PWRs) and boiling water reactors (BWRs). 

For the steel components in PWRs, this section addresses only boric acid corrosion of external 

surfaces as a result of dripping borated water leaking from an adjacent PWR component. 

System Interfaces 

The structures and components covered in this section belong to the Steam and Power 

Conversion Systems in PWRs and BWRs (for example, see system interfaces in VIII.A to VIII.G 

for details).

material/environment combinations, which may be found throughout the steam and power 

conversion system’s structures and components. For the material/environment combinations in 

this part, aging effects are not expected to degrade the ability of the structure or component to 

perform its intended function for the subsequent period of extended operation. With the exception 

of components within the scope of American Society of Mechanical Engineers Boiler and 

Pressure Vessel Code (ASME Code), Section XI or for those where a further evaluation results in 

identifying aging effects and a corresponding AMP, no AMPs for these structures and 

components are required. 

System Interfaces 

The SCs covered in this section belong to the steam and power conversion system in pressurized 

water reactors (PWRs) and boiling water reactors (BWRs) (for example, see system interfaces in 

VIII.A to VIII.G for details).
