NUCLEAR REGULATORY COMMISSION
[NRC-2020-0160]
Changes to Subsequent License Renewal Guidance Documents
AGENCY: Nuclear Regulatory Commission.
ACTION: Draft interim staff guidance; request for comment.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for
use and to solicit public comment, three draft interim staff guidance
documents (ISGs) that propose changes to the NRC's subsequent license
renewal guidance documents. Specifically, the ISGs revise guidance
contained in NUREG-2191, ``Generic Aging Lessons Learned for Subsequent
License Renewal (GALL-SLR) Report,'' and NUREG-2192, ``Standard Review
Plan for Review of Subsequent License Renewal Applications for Nuclear
Power Plants.'' NUREG-2191 and NUREG-2192 were published in July 2017
and are not scheduled to be updated for several years. The proposed
changes to these documents are contained in the three draft ISGs that
update aging management criteria for mechanical, structural, and
electrical structures and components.
DATES: Submit comments by August 3, 2020. 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:

B. Submitting Comments
Please include Docket ID NRC-2020-0160 in your comment submission.
The NRC cautions you not to include identifying or contact

include identifying or contact information that they do not want to be
publicly disclosed in their comment submission. Your request should
state that the NRC does not routinely edit comment submissions to
remove such information before making the comment submissions available
to the public or entering the comment into ADAMS.
II. Background
The NRC staff has completed its safety reviews of the first three
Subsequent License Renewal Applications (SLRAs) for Turkey Point
Nuclear Generating Units 3 and 4, Peach Bottom Atomic Power Station,
Units 2 and 3, and Surry Power Station, Units 1 and 2. The NRC staff
used the guidance contained in NUREG-2191, ``Generic Aging Lessons
[[Page 39939]]
Learned for Subsequent License Renewal (GALL-SLR) Report,'' and NUREG-
2192, ``Standard Review Plan for Review of Subsequent License Renewal
Applications for Nuclear Power Plants'' to conduct its SLRA safety
reviews for those SLRAs. Since March 2019, the NRC staff held several
public meetings to consider lessons learned from these safety reviews
and identify areas where the technical guidance in NUREG-2191 and
NUREG-2192 could be improved or clarified and where new technical
guidance was warranted. The meetings summaries and respective ADAMS
Accession Numbers are listed under the ``Availability of Documents''
section of this document.
III. Specific Request for Comments
The NRC is issuing for use and to solicit public comment, three
draft ISGs that proposes changes to the NRC's subsequent license
renewal guidance in NUREG-2191 and NUREG-2192. NUREG-2191 and NUREG-
2192 were published in July 2017 and are not scheduled to be updated
for several years. The process of updating these NUREGs involves major
review and evaluation by the staff, the nuclear industry, and the
public, and will take approximately 5 years once the process begins.
Several SLRAs are scheduled for submittal to the NRC for review within
the next 2 years. Issuance of these ISGs is intended to provide
improvements in the effectiveness and efficiency of the preparation and
review of the SLRAs.
The proposed changes to NUREG-2191 and NUREG-2192 are contained in
three draft ISGs that update aging management criteria for mechanical,
structural, and electrical structures and components. In addition,
minor edits are proposed where errors were identified in the existing
guidance.
