NUCLEAR REGULATORY COMMISSION

[NRC-2021-0231]

Guide for Assessing, Monitoring, and Mitigating Aging Effects on 
Electrical Equipment Used in Nuclear Power Generating Stations

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory guide; request for comment.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for 
public comment a draft regulatory guide (DG), DG-1393, ``Guide for 
Assessing, Monitoring, and Mitigating Aging Effects on Electrical 
Equipment Used in Nuclear Power Generating Stations.'' This proposed DG 
describes methods that are acceptable to the NRC staff to use for 
assessing, monitoring, and mitigating aging effects on electrical 
equipment used in nuclear power generating stations.

DATES: Submit comments by March 7, 2022. Comments received after this 
date will be considered if it is practical to do so, but the NRC is 
able to ensure consideration only for comments received on or before 
this date.

to the public or entering the comment into ADAMS.

II. Additional Information

    The NRC is issuing for public comment a DG in the NRC's 
``Regulatory Guide'' series. This series was developed to describe 
methods that are acceptable to the NRC staff for implementing specific 
parts of the agency's regulations, to explain techniques that the staff 
uses in evaluating specific issues or postulated events, and to 
describe information that the staff needs in its review of applications 
for permits and licenses.
    The DG, entitled ``Guide for Assessing, Monitoring, and Mitigating 
Aging Effects on Electrical Equipment Used in Nuclear Power Generating 
Stations,'' is a proposed new Regulatory Guide 1.248 and is being 
issued with a temporary identification of Draft Regulatory Guide, DG-
1393.
    Nuclear power plants (NPPs) licensed under Parts 50 and 52 of title 
10 of the Code of Federal Regulations (10 CFR), are required to monitor 
the performance or condition of Structures, Systems and Components 
(SSCs) against licensee-established goals, in a manner sufficient to 
provide reasonable assurance that these SSCs can fulfill their intended 
functions. Further, applicants for and holders of NPP renewed licenses 
under 10 CFR part 54 are required to demonstrate that the effects of 
aging will be adequately managed for the period of extended operation. 
DG-1393 describes a method that the NRC staff considers acceptable in 
complying with NRC regulations for assessing, monitoring, and 
mitigating aging effects on electrical equipment in NPPs.

III. Backfitting, Forward Fitting, and Issue Finality

    Issuance of DG-1393, if finalized, would not constitute backfitting 
as that term is defined in 10 CFR 50.109, ``Backfitting,'' and as 
described in NRC Management Directive (MD) 8.4, ``Management of 
Backfitting, Forward Fitting, Issue Finality, and Information 
Requests''; would not constitute forward fitting as that term is 
defined and described in MD 8.4; and would not affect issue finality of 
any approval issued under 10 CFR part 52, ``Licenses, Certificates, and 
Approvals for Nuclear Power Plants.'' As explained in DG-1393, 
applicants and licensees are not required to comply with the positions 
set forth in DG-1393.

    Dated: January 31, 2022.
