II. Background This draft LR–ISG describes changes to the aging management guidance for steam generator components in NUREG–1801 (GALL Report), Revision 2, and NUREG–1800 (SRP–LR), Revision 2. The draft LR–ISG revises GALL Report AMP XI.M19, ‘‘Steam Generators,’’ and SRP–LR Sections 3.1.2.2.11 and 3.1.3.2.11, ‘‘Cracking Due to Primary Water Stress Corrosion Cracking.’’ Specifically, this LR–ISG addresses the changes to aging management guidance for managing: (a) cracking due to primary water stress corrosion cracking in divider plate assemblies and tube-to-tubesheet welds, and (b) loss of material due to boric acid corrosion in steam generator heads and tubesheets. In addition, changes are made to the associated AMR items in the GALL Report and SRP–LR. This draft LR–ISG also revises the Final Safety Analysis Report supplement for the AMP that is documented in Table 3.0–1, ‘‘FSAR Supplement for Aging Management of Applicable Systems’’ of the SRP–LR. These changes provide one acceptable approach for managing the associated aging effects for steam generator components within the scope of the license renewal rule (part 54 of title 10 of the Code of Federal Regulations (10 CFR), ‘‘Requirements for Renewal of Operating Licenses for Nuclear Power Plants’’). A licensee may cite LR–ISG– 2016–01 in its license renewal application until the guidance in this LR–ISG is incorporated into the license renewal guidance documents (i.e., GALL Report and SRP–LR). The NRC issues LR–ISGs to communicate insights and lessons learned and to address emergent issues not covered in license renewal guidance documents, such as the GALL Report E:\FR\FM\07JNN1.SGM 07JNN1 Federal Register / Vol. 81, No. 109 / Tuesday, June 7, 2016 / Notices and SRP–LR. In this way, the NRC staff and stakeholders may use the guidance in an LR–ISG document before it is incorporated into a formal license renewal guidance document revision. The NRC staff issues LR–ISGs in accordance with the LR–ISG Process, Revision 2 (ADAMS Accession No. ML100920158), for which a notice of availability was published in the Federal Register on June 22, 2010 (75 FR 35510). The NRC also plans to consider the information in this LR–ISG and make corresponding changes when finalizing the draft aging management guidance for the subsequent license renewal period (i.e., up to 80 years of operation), which is documented in draft NUREG– 2191, ‘‘Generic Aging Lessons Learned for Subsequent License Renewal (GALL–SLR) Report,’’ and draft NUREG–2192, ‘‘Standard Review Plan for Review of Subsequent License Renewal Applications for Nuclear Power Plants,’’ if it is practicable to do so in terms of the guidance development schedule. III. Proposed Action By this action, the NRC is requesting public comments on draft LR–ISG– 2016–01. This LR–ISG proposes certain revisions to NRC guidance on implementation of the requirements in 10 CFR part 54. The NRC staff will make a final determination regarding issuance of the LR–ISG after it considers any public comments received in response to this request. IV. Backfitting asabaliauskas on DSK3SPTVN1PROD with NOTICES Issuance of this LR–ISG in final form would not constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule). As discussed in the ‘‘Backfitting’’ section of draft LR–ISG–2016–01, the LR–ISG is directed to holders of operating licenses who are currently in the license renewal process. The LR– ISG is not directed to holders of operating licenses or combined licenses until they apply for license renewal. The LR–ISG also is not directed to licensees who already hold renewed operating licenses. However, the NRC could also use the LR–ISG in evaluating voluntary, licensee-initiated changes to previously-approved AMPs. Dated at Rockville, Maryland, this 31st day of May, 2016.

II. Background

    This draft LR-ISG describes changes to the aging management 
guidance for steam generator components in NUREG-1801 (GALL Report), 
Revision 2, and NUREG-1800 (SRP-LR), Revision 2. The draft LR-ISG 
revises GALL Report AMP XI.M19, ``Steam Generators,'' and SRP-LR 
Sections 3.1.2.2.11 and 3.1.3.2.11, ``Cracking Due to Primary Water 
Stress Corrosion Cracking.'' Specifically, this LR-ISG addresses the 
changes to aging management guidance for managing: (a) cracking due to 
primary water stress corrosion cracking in divider plate assemblies and 
tube-to-tubesheet welds, and (b) loss of material due to boric acid 
corrosion in steam generator heads and tubesheets. In addition, changes 
are made to the associated AMR items in the GALL Report and SRP-LR. 
This draft LR-ISG also revises the Final Safety Analysis Report 
supplement for the AMP that is documented in Table 3.0-1, ``FSAR 
Supplement for Aging Management of Applicable Systems'' of the SRP-LR.
    These changes provide one acceptable approach for managing the 
associated aging effects for steam generator components within the 
scope of the license renewal rule (part 54 of title 10 of the Code of 
Federal Regulations (10 CFR), ``Requirements for Renewal of Operating 
Licenses for Nuclear Power Plants''). A licensee may cite LR-ISG-2016-
01 in its license renewal application until the guidance in this LR-ISG 
is incorporated into the license renewal guidance documents (i.e., GALL 
Report and SRP-LR).
    The NRC issues LR-ISGs to communicate insights and lessons learned 
and to address emergent issues not covered in license renewal guidance 
documents, such as the GALL Report

[[Page 36613]]

and SRP-LR. In this way, the NRC staff and stakeholders may use the 
guidance in an LR-ISG document before it is incorporated into a formal 
license renewal guidance document revision. The NRC staff issues LR-
ISGs in accordance with the LR-ISG Process, Revision 2 (ADAMS Accession 
No. ML100920158), for which a notice of availability was published in 
the Federal Register on June 22, 2010 (75 FR 35510).
    The NRC also plans to consider the information in this LR-ISG and 
make corresponding changes when finalizing the draft aging management 
guidance for the subsequent license renewal period (i.e., up to 80 
years of operation), which is documented in draft NUREG-2191, ``Generic 
Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) 
Report,'' and draft NUREG-2192, ``Standard Review Plan for Review of 
Subsequent License Renewal Applications for Nuclear Power Plants,'' if 
it is practicable to do so in terms of the guidance development 
schedule.

III. Proposed Action

    By this action, the NRC is requesting public comments on draft LR-
ISG-2016-01. This LR-ISG proposes certain revisions to NRC guidance on 
implementation of the requirements in 10 CFR part 54. The NRC staff 
will make a final determination regarding issuance of the LR-ISG after 
it considers any public comments received in response to this request.

IV. Backfitting

    Issuance of this LR-ISG in final form would not constitute 
backfitting as defined in 10 CFR 50.109 (the Backfit Rule). As 
discussed in the ``Backfitting'' section of draft LR-ISG-2016-01, the 
LR-ISG is directed to holders of operating licenses who are currently 
in the license renewal process. The LR-ISG is not directed to holders 
of operating licenses or combined licenses until they apply for license 
renewal. The LR-ISG also is not directed to licensees who already hold 
renewed operating licenses. However, the NRC could also use the LR-ISG 
in evaluating voluntary, licensee-initiated changes to previously-
approved AMPs.

    Dated at Rockville, Maryland, this 31st day of May, 2016.
    For the Nuclear Regulatory Commission.
Dennis C. Morey,
Acting Deputy Director, Division of License Renewal, Office of Nuclear 
Reactor Regulation.
