NUCLEAR REGULATORY COMMISSION
[NRC-2021-0143]
Cyber Security Programs for Nuclear Power Reactors
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-5061, Revision 1,
``Cyber Security Programs for Nuclear Power Reactors.'' DG 5061,
Revision 1, incorporates reference to industry whitepapers on
identifying safety, important to safety, balance of plant, and
emergency preparedness Critical Digital Assets. It also clarifies
guidance on defense-in-depth for cyber security and includes updated
text based on the latest National Institute of Standards and Technology
(NIST) and International Atomic Energy Agency cyber security guidance.
Specifically, this proposed revision clarifies issues identified from
cyber security inspections, insights gained through the Security
Frequently Asked Questions (SFAQ) process, documented cyber security
attacks, new technologies, and new regulations. This proposed revision
also considers the changes in the most recent revision to the NIST
Special Publications (SP) 800-53, upon which Revision 0 of Regulatory
Guide (RG) 5.71, ``Cyber Security Programs for Nuclear Facilities'' was
based.
DATES: Submit comments by May 2, 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.
ADDRESSES: You may submit comments by any of the following methods;
however, the NRC encourages electronic comment submission through the

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. Additional Information
The NRC is issuing for public comment a DG 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, 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 ``Cyber Security Programs for Nuclear Power
Reactors,'' is temporarily identified by its task number, DG-5061,
Revision 1 (ADAMS Accession No. ML21095A329) is a proposed revision to
RG 5.71, ``Cyber Security Programs for Nuclear Facilities.'' It
provides NRC licensees with guidance on meeting the cyber security
requirements described in section 73.54 of title 10 of the Code of
Federal Regulations (10 CFR), ``Protection of digital computer and
communication systems and networks.''
The staff is also issuing for public comment a draft regulatory
analysis (ADAMS Accession No. ML21130A636). The staff developed the
regulatory analysis to assess the value of revising RG 5.71 as well as
alternative courses of action.
DG-5061, Revision 1, clarifies issues identified from cyber
security inspections, insights gained through the SFAQ process, lessons
learned from international and domestic cyber security attacks, new
technologies, and new regulations. In addition, it considers changes in
NIST SP 800-53, upon which Revision 0 of RG 5.71 was based. In 2010,
the Commission issued Staff Requirements Memorandum (SRM), SRM-COMWCO-
10-0001 (ADAMS Accession No. ML102940009) which clarified the scope of
the cyber security rule regarding balance of plant (BOP) systems. This
proposed revision to RG 5.71 includes guidance for structures, systems,
and components in the BOP systems.
III. Backfitting, Forward Fitting, and Issue Finality
DG-5061, Revision 1, if finalized, would revise RG 5.71, which
describes methods acceptable for use by nuclear power plant licensees
in meeting the requirements for the cyber security requirements in 10
CFR 73.54. Issuance of DG-5061 Revision 1, if finalized, would not
constitute backfitting as 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''; constitute forward fitting as that term is defined and
described in MD 8.4; or affect the issue finality of any approval
issued under 10 CFR part 52, ``Licenses, certifications, and approvals
for nuclear power plants.'' As explained in DG-5061 Revision 1,
applicants and licensees would not be required to comply with the
positions set forth in DG-5061.
IV. Submitting Suggestions for Improvement of Regulatory Guides
A member of the public may, at any time, submit suggestions to the
NRC for improvement of existing RGs or for the development of new RGs.
Suggestions can be submitted on the NRC's public website at https://www.nrc.gov/reading-rm/doc-collections/reg-guides/contactus.html.
Suggestions will be considered in future updates and enhancements to
the ``Regulatory Guide'' series.
