    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 Start Printed Page 17501being 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.
