NUCLEAR REGULATORY COMMISSION

[NRC-2015-0251]


Generic Aging Lessons Learned for Subsequent License Renewal 
Report and Standard Review Plan for Review of Subsequent License 
Renewal Applications for Nuclear Power Plants

AGENCY: Nuclear Regulatory Commission.

ACTION: Supplemental staff guidance; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is soliciting 
public comment on supplemental guidance to draft NUREG-2191, ``Generic

for Review of Subsequent License Renewal Applications for Nuclear Power 
Plants'' (SRP-SLR). This supplemental guidance was developed subsequent 
to the release of draft NUREG-2191 and NUREG-2192 on December 23, 2015. 
Changes to the supplemental guidance will be incorporated into the 
final versions of NUREG-2191 and NUREG-2192.

DATES: Comments must be filed by May 31, 2016. Comments received after 
this date will be considered, if it is practical to do so, but the 
Commission is able to ensure consideration only for comments received 
on or before this date.

ADDRESSES: You may submit comments by any of the following methods:
     Federal Rulemaking Web site: Go to http://www.regulations.gov and search for Docket ID NRC-2015-0251. Address

II. Background

    On December 23, 2015, the NRC published in the Federal Register (80 
FR 79956) the draft NUREG-2191, ``Generic Aging Lessons Learned for 
Subsequent License Renewal (GALL-SLR) Report,'' Vol. I and II and draft 
NUREG-2192, ``Standard Review Plan for Review of Subsequent License 
Renewal Applications for Nuclear Power Plants'' (SRP-SLR), which are 
available under ADAMS Accession Nos. ML15348A111, ML15348A153, and 
ML15348A265, respectively. These draft documents describe methods 
acceptable to the NRC staff for granting a subsequent license renewal 
(i.e., license renewal following 60 years of licensed operation) in 
accordance with the NRC's license renewal regulations, as well as 
techniques used by the NRC staff in evaluating applications for 
subsequent license renewal.
    The changes described in the GALL-SLR and SRP-SLR Supplemental 
Staff Guidance were developed subsequent to the release of the draft 
versions of NUREG-2191 and NUREG-2192 and are

[[Page 17501]]

being released for public comments. Comments received on the changes 
proposed in this document will be addressed along with comments 
received on the draft versions of NUREG-2191 and NUREG-2192. The 
changes will then be incorporated into the final versions of NUREG-2191 
and NUREG-2192.
    The topical areas addressed in this supplement to the publically-
available GALL-SLR Report and SRP-SLR are as follows: (A) selective 
leaching of ductile iron; (B) cracking due to stress corrosion cracking 
and intergranular stress corrosion cracking; (C) changes to further 
evaluation, aging management program (AMP) XI.M29, ``Aboveground 
Metallic Tanks,'' AMP XI.M36, ``External Surfaces Monitoring of 
Mechanical Components,'' and aging management review (AMR) line items 
to address cracking and loss of material for aluminum and stainless 
steel components; (D) a new title for AMP XI.M29; (E) issuance of LR-
ISG-2015-01, ``Changes to Buried and Underground Piping and Tank 
Recommendations;'' (F) minor technical and editorial changes to AMR 
line items and AMPs; and (G) response to certain initial comments from 
the industry as presented at a public meeting on January 21, 2016.

III. Backfitting and Issue Finality

    This supplement contains guidance on one acceptable approach for 
managing the associated aging effects during subsequent periods of 
extended operation for components within the scope of subsequent 
license renewal. Issuance of this supplemental guidance does not 
constitute backfitting as defined in 10 CFR 50.109(a)(1), and the NRC 
staff did not prepare a backfit analysis for issuing this supplement. 
More information is provided under the ``Backfitting and Issue 
Finality'' section of the supplemental guidance.

    Dated at Rockville, Maryland, this 23rd day of March, 2016.

    For the Nuclear Regulatory Commission.
Dennis C. Morey,
Chief, Aging Management of Reactor Systems Branch, Division of License 
Renewal, Office of Nuclear Reactor Regulation.
