NUCLEAR REGULATORY COMMISSION
[NRC-2018-0131]
Monitoring the Effectiveness of Maintenance at Nuclear Power
Plants
AGENCY: Nuclear Regulatory Commission.
ACTION: Regulatory guide; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing
Revision 4 to Regulatory Guide (RG) 1.160, ``Monitoring the
Effectiveness of Maintenance at Nuclear Power Plants.'' Regulatory
Guide 1.160, Revision 4, has been revised to address new issues
identified since Revision 3 of RG 1.160 was issued. This RG endorses,
with clarifications, NUMARC 93-01, ``Industry Guidelines for Monitoring
the Effectiveness of Maintenance at Nuclear Power Plants,'' Revision
4F. The proposed revision describes methods that are acceptable to the
NRC staff for compliance with the requirements for monitoring the
effectiveness of maintenance at nuclear power plants.
DATES: Revision 4 to RG 1.160 is available on September 26, 2018.

SUPPLEMENTARY INFORMATION:
I. Discussion
The NRC is issuing a revision to an existing guide in the NRC's
``Regulatory Guide'' series. This series was developed to describe and
make available to the public information regarding methods that are
acceptable to the NRC staff for implementing specific parts of the
agency's regulations, techniques that the NRC staff uses in evaluating
specific issues or postulated events, and data that the NRC staff needs
in its review of applications for permits and licenses.
Revision 4 of RG 1.160 was issued with a temporary identification
of Draft Regulatory Guide, DG-1336. This revision of the guide
addresses new issues identified since the guide was previously issued
and updates the guidance by endorsing Revision 4F of NUMARC 93-01,
``Industry Guideline for Monitoring the Effectiveness of Maintenance at
Nuclear Power Plants.'' NUMARC 93-01, Revision 4F addresses the
application of the Maintenance Rule (title 10 of the Code of Federal
Regulations (CFR) section 50.65) to address the use of diverse and
flexible coping strategies.
II. Additional Information
The NRC published a notice of the availability of DG-1336 in the
Federal Register on June 28, 2018 (83 FR 30469) for a 30-day public
comment period. The public comment period closed on July 30, 2018.
Public comments on DG-1336 and the staff responses to the public
comments are available under ADAMS under Accession No. ML18220B279.
III. Congressional Review Act
This RG is a rule as defined in the Congressional Review Act (5
U.S.C. 801-808). However, the Office of Management and Budget has not
found it to be a major rule as defined in the Congressional Review Act.
IV. Backfitting and Issue Finality
This RG describes methods acceptable to the staff of the NRC for
demonstrating compliance with the provisions of 10 CFR 50.65,
``Requirements for Monitoring the Effectiveness of Maintenance at
Nuclear Power Plants,'' of 10 CFR part 50, ``Domestic Licensing of
Production and Utilization Facilities.'' Issuance of this RG does not
constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule)
and is not otherwise inconsistent with the issue finality provisions in
10 CFR part 52. As discussed in the ``Implementation'' section of this
RG, the NRC has no current intention to impose this guidance on holders
of current operating licenses or combined licenses.
This RG may be applied to applications for amendments to operating
licenses or combined licenses
[[Page 48660]]
docketed by the NRC as of the date of issuance, as well as future
applications submitted after the issuance of this regulatory guide.
Such action would not constitute backfitting as defined in the Backfit
Rule or be otherwise inconsistent with the applicable issue finality
provision in 10 CFR part 52, inasmuch as such applicants or potential
applicants, with certain exceptions described below, are not within the
scope of entities that are the subject of the Backfit Rule or the
relevant issue finality provisions in 10 CFR part 52. This RG may be
used by existing holders of combined licenses and operating licenses in
accordance with their existing licensing basis and applicable
regulatory requirements.
The exceptions to the general principle are applicable whenever a
combined license applicant references a 10 CFR part 52 license (i.e.,
an early site permit or a manufacturing license) and/or 10 CFR part 52
regulatory approval (i.e., a design certification rule or design
approval). However, the matters addressed in this RG (monitoring the
effectiveness of maintenance at nuclear power plants) have not
previously been proposed for resolution in a 10 CFR part 52 license or
regulatory approval. The NRC staff does not, at this time, intend to
impose the positions represented in the RG in a manner that is
inconsistent with any issue finality provisions in these 10 CFR part 52
licenses and regulatory approvals. If, in the future, the NRC staff
seeks to impose a position in this RG in a manner that does not provide
issue finality as described in the applicable issue finality provision,
then the NRC staff must address the criteria for avoiding issue
finality as described in the applicable issue finality provision.
Further information on the staff's use of the RG is contained in
the RG under Section D, ``Implementation.''
Dated at Rockville, Maryland, this 20th day of September, 2018.
For the Nuclear Regulatory Commission.

Chief, Regulatory Guidance and Generic Issues Branch, Division of
Engineering, Office of Nuclear Regulatory Research.
