B. Submitting Comments 

Written comments and 

recommendations for the proposed 

information collection should be sent 

within 30 days of publication of this 

notice to www.reginfo.gov/public/do/ 

PRAMain. Find this particular 

information collection by selecting 

‘‘Currently under Review—Open for 

Public Comments’’ or by using the 

search function. 

The NRC cautions you not to include 

identifying or contact information in 

comment submissions that you do not 

want to be publicly disclosed in your 

comment submission. All comment 

submissions are posted at https://

www.regulations.gov/ and entered into 

ADAMS. Comment submissions are not 

routinely edited to remove identifying 

or contact information. 

If you are requesting or aggregating 

comments from other persons for 

submission to the OMB, then you 

should inform those persons not to 

include identifying or contact 

information that they do not want to be 

publicly disclosed in their comment 

submission. Your request should state 

that comment submissions are not 

routinely edited to remove such 

information before making the comment 

submissions available to the public or 

entering the comment into ADAMS. 

II. Background 

Under the provisions of the 

Paperwork Reduction Act of 1995 (44 

U.S.C. Chapter 35), the NRC recently 

submitted a request for renewal of an 

existing collection of information to 

OMB for review entitled, ‘‘General 

Domestic Licenses for Byproduct 

Material.’’ The NRC hereby informs 

potential respondents that an agency 

may not conduct or sponsor, and that a 

person is not required to respond to, a 

collection of information unless it 

displays a currently valid OMB control 

number. 

The NRC published a Federal 

Register notice with a 60-day comment 

period on this information collection on 

March 23, 2021 (86 FR 15512). 

1. The title of the information 

collection: Part 31 of title 10 of the Code 

of Federal Regulations (10 CFR), 

‘‘General Domestic Licenses for 

Byproduct Material.’’ 

2. OMB approval number: 3150–0016. 

3. Type of submission: Extension. 

4. The form number, if applicable: 

Not applicable. 

5. How often the collection is required 

or requested: Reports are submitted as 

events occur. General license 

registration requests may be submitted 

at any time. Changes to the information 

on the registration may be submitted as 

they occur. Devices meeting certain 

criteria must be registered annually. 

6. Who will be required or asked to 

respond: Persons receiving, possessing, 

using, or transferring devices containing 

byproduct material. 

7. The estimated number of annual 

responses: 167,858 (12,277 reporting 

responses + 181 third-party responses + 

155,400 recordkeepers). 

8. The estimated number of annual 

respondents: 155,400 (18,500 NRC 

licensee respondents + 136,900, 

Agreement State licensee respondents). 

9. The estimated number of hours 

needed annually to comply with the 

information collection requirement or 

request: 43,803 hours (4,905 reporting 

hours + 48 third-party disclosure hours 

+ 38,850 recordkeeping hours). 

10. Abstract: 10 CFR part 31, ‘‘General 

Domestic Licenses for Byproduct 

Material’’ establishes general licenses 

for the possession and use of byproduct 

material in certain devices. General 

licensees are required to keep testing 

records and submit event reports 

identified in 10 CFR part 31, which 

assist the NRC in determining, with 

reasonable assurance, that devices are 

operated safely and without radiological 

hazard to users or the public.

NUCLEAR REGULATORY 

COMMISSION 

[NRC–2021–0141] 

Evaluating the Habitability of a Nuclear 

Power Plant Control Room During a 

Postulated Hazardous Chemical 

Release 

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–1387, ‘‘Evaluating the Habitability 

of a Nuclear Power Plant Control Room 

during a Postulated Hazardous 

Chemical Release.’’ This DG is a 

proposed Revision 2 to Regulatory 

Guide (RG) 1.78, which describes an 

approach that is acceptable to the NRC 

staff to meet regulatory requirements for 

evaluating the habitability of a nuclear 

power plant control room during a 

postulated hazardous chemical release. 

Releases of hazardous chemicals, onsite 

or off-site, can result in the nearby 

control room becoming uninhabitable. 

DATES: Submit comments by August 27, 

2021. 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. 

Although a time limit is given, 

comments and suggestions in 

connection with items for inclusion in 

guides currently being developed or 

improvements in all published guides 

are encouraged at any time. 

ADDRESSES: You may submit comments 

by any of the following methods; 

however, the NRC encourages electronic 

comment submission through the 

Federal Rulemaking website: 

• Federal Rulemaking Website: Go to 

https://www.regulations.gov and search

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, ‘‘Evaluating the 

Habitability of a Nuclear Power Plant 

Control Room during a Postulated 

Hazardous Chemical Release,’’ is 

temporarily identified by its task 

number, DG–1387 (ADAMS Accession 

No. ML21119A157). The proposed 

revision of this guide (Revision 2) 

presents up-to-date and defense-indepth guidance using the latest 

scientific methods and the updated, 

NRC-endorsed computer code for 

control room habitability evaluation 

called HABIT. HABIT is an integrated 

set of computer codes that the NRC uses 

to evaluate control room habitability 

and estimate the control room 

personnel’s exposure to a chemical 

release. DG–1387 describes an approach 

that is acceptable to the NRC staff to 

meet the requirements of part 50 of title 

10 of the Code of Federal Regulations 

(10 CFR), ‘‘Domestic licensing of 

production and utilization facilities,’’ 

appendix A, ‘‘General Design Criteria 

for Nuclear Power Plants,’’ General 

Design Criterion 19, ‘‘Control Room,’’ 

for evaluating the habitability of a 

nuclear power plant control room 

during a postulated hazardous chemical 

release. 

Revision 1 of RG 1.78 endorsed an 

earlier version of the HABIT code, 

which is described in NUREG/CR–6210, 

Supplement 1, ‘‘Computer Codes for 

Evaluation of Control Room Habitability 

(HABIT V1.1),’’ issued October 1998 

(ADAMS Accession No. ML063480558). 

More recently, the NRC staff endorsed a 

newer version of the HABIT code in 

NUREG–2244, ‘‘HABIT 2.2: Description 

of Models and Methods,’’ issued May 

2021 (ADAMS Accession No. 

ML21120A069). NUREG–2244 is 

incorporated into Revision 2 of this 

proposed guide. 

The staff is also issuing for public 

comment a draft regulatory analysis 

(ADAMS Accession No. ML21119A159). 

The staff developed the regulatory 

analysis to assess the value of revising 

RG 1.78 as well as alternative courses of 

action. 

III. Backfitting, Forward Fitting, and 

Issue Finality 

Issuance of DG–1387, 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’’; 

would not 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 reactors.’’ As 

explained in DG–1387, applicants and 

licensees would not be required to 

comply with the positions set forth in 

DG–1387.
