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/readingrm/doc-collections/reg-guides/ 

contactus.html. Suggestions will be 

considered in future updates and 

enhancements to the ‘‘Regulatory 

Guide’’ series.

COMMISSION 

[NRC–2022–0054] 

Guidance for the Application of 

Radiological Sabotage Design-Basis 

Threat in the Design, Development, 

and Implementation of a Physical 

Security Program That Meets 10 CFR 

73.55 Requirements 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Regulatory guide; issuance. 

SUMMARY: The U.S. Nuclear Regulatory 

Commission (NRC) is issuing Revision 1 

to Regulatory Guide (RG) 5.69, 

‘‘Guidance for the Application of 

Radiological Sabotage Design-Basis 

Threat in the Design, Development, and 

Implementation of a Physical Security 

Program that Meets 10 CFR 73.55 

Requirements,’’ as a final RG. RG 5.69 

provides a method that the NRC staff 

finds acceptable for an applicant or 

licensee to use in applying the designbasis threats (DBTs) in the development 

of a physical security program that 

meets the requirements of NRC 

regulations. Through interactions with 

stakeholders during physical security 

inspections, including security baseline 

inspections, force-on-force exercises, 

and enforcement activities, the NRC 

identified areas where a need for 

additional clarity and/or sufficient 

technical information is warranted. 

Revision 1 to RG 5.69 addresses these 

areas. In addition, revisions to this 

guidance include changes to the DBT 

adversary characteristics necessary to 

align with changes to NRC security 

requirements made since the 

publication of Revision 0 to RG 5.69 in 

2007. 

DATES: Revision 1 to RG 5.69 is available 

on March 3, 2022. 

ADDRESSES: Please refer to Docket ID 

NRC–2022–0054 when contacting the 

NRC about the availability of 

information regarding this document. 

Revision 1 to RG 5.69 contains 

Safeguards Information (SGI). Therefore, 

this RG is being withheld from public 

disclosure, but is available to those 

affected licensees and cleared 

stakeholders who qualify for access and 

have a demonstrated need-to-know. For 

access to Revision 1 to RG 5.69, contact 

the individuals listed in the FOR

FURTHER INFORMATION CONTACT section.

SUPPLEMENTARY INFORMATION: 

I. Discussion 

The NRC is issuing a revision to an 

existing RG 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 1 to RG 5.69 incorporates 

methods to apply requirements of 

updated regulations and lessons-learned 

from regulatory oversight, including

findings, enforcement actions, Security 

Frequently Asked Questions, and other 

regulatory documents (e.g., generic 

communications). This RG clarifies DBT 

advesary characteristics and capabilities 

identified through interactions with 

stakeholders and inspection activities 

since the original publication of the 

guide. 

II. Additional Information 

Revision 1 to RG 5.69 contains SGI. 

Accordingly, this RG is being withheld 

from public disclosure. It will be made 

available to those affected licensees and 

cleared stakeholders who have an 

established need-to-know for access to 

the RG. The NRC did not announce the 

availaibility of the draft RG for public 

comment because the guide contains 

SGI and Official Use Only—SecurityRelated Information. Nonetheless, the 

NRC is issuing this notice to inform the 

public of the issuance of the final RG. 

On December 23, 2015, the NRC 

issued an email (Agencywide 

Documents Access and Management 

System (ADAMS) Accession No. 

ML16007A567) transmitting the draft 

RG for comment to cleared stakeholders 

who demonstrated a need-to-know for 

access to the document. The 

stakeholder’s comment period closed on 

March 7, 2016. The NRC received 

several comments from stakeholders. 

The comments and the associated 

comment resolution contain SGI and are 

not available to the public. In addition, 

per Staff Requirements Memorandum 

(SRM)—SECY–18–0110, ‘‘Proposed 

Revision to Regulatory Guide 5.69, 

‘‘Guidance for the Application of the 

Radiological Sabotage Design-Basis 

Threat for Nuclear Power Reactors,’’ ’’ 

dated November 18, 2021 (Non-Publicly 

Available), staff completed the 

Commission’s approved edits to the 

document as appropriate. 

For access to RG 5.69, Revision 1, 

contact the individuals listed in the FOR

FURTHER INFORMATION CONTACT section. 

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, Forward Fitting, and 

Issue Finality 

This RG provides updated guidance 

on the methods acceptable to the NRC 

staff for complying with the NRC’s 

regulations associated with the designbasis threat for nuclear power reactors. 

The RG applies to current licensees and 

future applicants for, and holders of: 

• Operating licenses for nuclear 

power reactors under part 50 of title 10 

of the Code of Federal Regulations (10 

CFR); and combined licenses for nuclear 

power reactors under 10 CFR part 52; 

• operating licenses for nuclear 

power reactors that are required to 

protect safeguards information regulated 

by the Commission by Order EA–03– 

086, ‘‘Order Requiring Compliance with 

Revised Design Basis Threat for 

Operating Power Reactors,’’ dated April 

29, 2003; and 

• operating licenses for nuclear 

power reactors that are required to 

protect safeguards information regulated 

by the Commission by Order EA–06– 

037, ‘‘Order Requiring Compliance with 

Updated Adversary Characteristic,’’ 

dated March 20, 2006. 

Issuance of this RG does 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 the RG, 

licensees are not required to comply 

with the positions set forth in this RG, 

and the NRC staff does not intend to use 

the guidance in this RG to support NRC 

staff actions in a manner that would 

constitute backfitting or forward fitting 

or affect the issue finality of any 

approval issued under 10 CFR part 52. 

If, in the future, the NRC seeks to 

impose a position in this RG in a 

manner that constitutes backfitting or 

forward fitting or affects the issue 

finality for a 10 CFR part 52 approval, 

then the NRC will address the 

backfitting provision in 10 CFR 50.109, 

the forward fitting provision of MD 8.4, 

or the applicable issue finality provision 

in 10 CFR part 52, respectively.
