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:
     Federal Rulemaking Website: Go to https://www.regulations.gov and search for Docket ID NRC-2020-0160. Address

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.
