Regulatory Guide: Basis for 

Withdrawal of Regulatory Guides in 

Division 6, ‘‘Products,’’ and Division 10, 

‘‘General’’ 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Regulatory guide; withdrawal. 

SUMMARY: The U.S. Nuclear Regulatory 

Commission (NRC) is withdrawing 

Regulatory Guides (RGs) in Division 6, 

‘‘Products,’’ (RGs 6.1, 6.2, 6.4, 6.5, and 

6.9), and Division 10, ‘‘General,’’ (RGs 

10.2, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8, 

and 10.9). These RGs are being 

withdrawn because there is more up-todate guidance in the NUREG–1556 

Series, ‘‘Consolidated Guidance About 

Materials Licenses,’’ making these RGs 

obsolete. 

DATES: The withdrawal of the RGs listed 

in this document takes effect on January 

31, 2024.

SUPPLEMENTARY INFORMATION: 

I. Discussion 

The NRC is withdrawing RGs in 

Division 6, ‘‘Products,’’ (RGs 6.1, 6.2, 

6.4, 6.5, and 6.9), and in Division 10, 

‘‘General,’’ (RGs 10.2, 10.3, 10.4, 10.5, 

10.6, 10.7, 10.8, and 10.9). The titles of 

these RGs are as follows: 

(1) RG 6.1, Leak Testing Radioactive 

Brachytherapy Sources; 

(2) RG 6.2, Integrity and Test Specifications 

for Selected Brachytherapy Sources; 

(3) RG 6.4, Verification of Containment 

Properties of Sealed Radioactive Sources; 

(4) RG 6.5, General Safety Standard for 

Installations Using Nonmedical Sealed 

Gamma-Ray Sources; 

(5) RG 6.9, Establishing Quality Assurance 

Programs for the Manufacture and 

Distribution of Sealed Sources and Devices 

Containing Byproduct Material; 

(6) RG 10.2, Guidance to Academic 

Institutions Applying for Specific Byproduct 

Material Licenses of Limited Scope; 

(7) RG 10.3, Guide for the Preparation of 

Applications for Special Nuclear Material 

Licenses for Less than Critical Mass 

Quantities; 

(8) RG 10.4, Guide for the Preparation of 

Applications for Licenses to Process Source 

Material; 

(9) RG 10.5, Applications for a Type A 

License of Broad Scope; 

(10) RG 10.6, Guide for the Preparation of 

Applications for an Industrial Radiography 

License; 

(11) RG 10.7, Guide for the Preparation of 

Applications for Licenses for Laboratory and 

Industrial Use of Small Quantities of 

Byproduct Material; 

(12) RG 10.8, Guide for the Preparation of 

Applications for Medical Use Programs; and 

(13) RG 10.9, Guide for the Preparation of 

Applications for Licenses for the Use of SelfContained Dry Source-Storage Gamma 

Irradiators. 

The NRC staff issued these RGs in the 

1970s and 1980s to comply with the 

regulations in title 10 of the Code of 

Federal Regulations (10 CFR), 10 CFR 

part 30, ‘‘Rules of General Applicability 

to Domestic Licensing of Byproduct 

Material,’’ 10 CFR part 33, ‘‘Specific 

Domestic Licenses of Broad Scope for 

Byproduct Material,’’ 10 CFR part 32, 

‘‘Specific Domestic Licenses to 

Manufacture or Transfer Certain Items 

Containing Byproduct Material,’’ 10 

CFR part 34, ‘‘Licenses for Industrial 

Radiography and Radiation Safety 

Requirements for Industrial 

Radiographic Operations,’’ 10 CFR part 

35, ‘‘Medical Use of Byproduct 

Material,’’ 10 CFR part 70 ‘‘Domestic 

Licensing of Special Nuclear Material,’’ 

10 CFR part 150 ‘‘Exemptions and 

Continued Regulatory Authority in 

Agreement States and in Offshore 

Waters under Section 274,’’ 10 CFR part 

20, ‘‘Standards for Protection Against 

Radiation,’’ 10 CFR part 71, ‘‘Packaging 

and Transportation of Radioactive 

Material,’’ and 10 CFR part 75, 

‘‘Safeguards on Nuclear Material— 

Implementation of Safeguards 

Agreements Between the United States 

and the International Atomic Energy 

Agency.’’ 

Since the staff has consolidated and 

follows the latest guidance pertinent to 

materials licensees found in the 

NUREG–1556 Series, ‘‘Consolidated 

Guidance About Materials Licenses,’’ 

these RGs became outdated. Because 

NUREG–1556 provides up-to-date 

guidance to NRC byproduct material 

licensees, the staff determined that these 

RGs needed to be withdrawn. The basis 

for the withdrawal is available under 

ADAMS Accession No. ML23333A446. 

Because these RGs are no longer 

needed, the NRC is withdrawing them. 

Withdrawal of an RG means that the 

guide no longer provides useful 

information or has been superseded by 

other guidance, technological 

innovations, congressional actions, or 

other events. The withdrawal of these 

RGs does not alter any prior or existing 


lotter on DSK11XQN23PROD with RULES1
6008 Federal Register / Vol. 89, No. 21 / Wednesday, January 31, 2024 / Rules and Regulations 

NRC licensing approval or the 

acceptability of licensee commitments 

to these RGs. Although these RGs are 

withdrawn, current licensees may 

continue to use them, and withdrawal 

does not affect any existing licenses or 

agreements. However, these RGs should 

not be used in future requests or 

applications for NRC licensing actions. 

II. Additional Information 

As noted in the Federal Register on 

December 9, 2022 (87 FR 75671), this 

document is being published in the 

‘‘Rules’’ section of the Federal Register 

to comply with publication 

requirements under 1 CFR chapter I. 

III. 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.

commercial or financial information 

that is customarily treated as private, 

that you actually treat as private, and 

that is relevant or responsive to this AD, 

it is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and they 

will not be placed in the public docket 

of this AD. Submissions containing CBI 

should be sent to David Kim, Aviation 

Safety Engineer, FAA, 3960 Paramount 

Boulevard, Lakewood, CA 90712;

that the FAA receives which is not 

specifically designated as CBI will be 

placed in the public docket for this 

rulemaking. 

Background 

The FAA has received a report of a 

manufacturing defect in the screws used 

inside Pacific Scientific Company 

buckle part number (P/N) 1111475 (all 

dash numbers) and P/N 1111548–01. 

The screws used to fasten the load plate 

to the body of the buckle were found to 

be susceptible to hydrogen 

embrittlement due to improper baking
