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. VerDate Sep<11>2014 17:16 Jul 27, 2021 Jkt 253001 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.

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, PO 00000 Frm 00219 Fmt 4703 Sfmt 4703 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.

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-in-depth 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

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.
