NUCLEAR REGULATORY COMMISSION

[NRC-2021-0147]


Evaluations of Explosions Postulated To Occur at Nearby 
Facilities and on Transportation Routes Near Nuclear Power Plants

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory guide; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing for 
public comment draft regulatory guide (DG)-1388, ``Evaluations of 
Explosions Postulated to Occur at Nearby Facilities and on 
Transportation Routes Near Nuclear Power Plants.'' This DG is proposed 
Revision 3 to Regulatory Guide (RG) 1.91. RG 1.91 describes methods 
that the NRC finds acceptable for applicants and licensees of nuclear 
power reactors to use in evaluating postulated accidental explosions at 
nearby facilities and transportation routes.

DATES: Submit comments by September 1, 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

B. Submitting Comments

    The NRC encourages electronic comment submission through the 
Federal Rulemaking website (https://www.regulations.gov). Please 
include Docket ID NRC-2021-0147 in your comment submission.
    The NRC cautions you not to include identifying or contact 
information that you do not want to be publicly disclosed in your 
comment submission. The NRC will post all comment submissions at 
https://www.regulations.gov as well as enter the comment submissions 
into ADAMS. The NRC does not routinely edit comment submissions to 
remove identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, 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 the NRC 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 
NRC's regulations, techniques that the staff uses in evaluating 
specific issues or postulated events, and data that the staff needs in 
its review of applications for permits and licenses.
    This proposed Revision 3 to RG 1.91, entitled ``Evaluations of 
Explosions Postulated to Occur at Nearby Facilities and on 
Transportation Routes Near Nuclear Power Plants,'' is temporarily 
identified by its task number, DG-1388 (ADAMS Accession No. 
ML21105A439). The staff is also issuing for public comment a draft 
regulatory analysis (ADAMS Accession No. ML21105A438).
    The NRC published Revision 2 of RG 1.91, ``Evaluations of 
Explosions Postulated to Occur on Transportation Routes near Nuclear 
Power Plants,'' in April 2013 to provide licensees and applicants with 
agency-approved guidance regarding methods acceptable to the NRC staff 
for determining if the risk of damage at the site caused by an 
accidental explosion at a nearby facility or on a transportation route 
is sufficiently high to warrant a detailed investigation to ensure 
safety-related systems, structures, and components are unaffected. The 
current version of RG 1.91 (Revision 2) does not reflect the changes 
and updates with respect to the following NRC report or current 
methodologies as appropriate.
    This proposed revision (Revision 3) reflects updates with 
information pertinent to addressing the recommendations of the NRC 
report entitled, ``Report of the U.S. Nuclear Regulatory Commission 
Expert Evaluation Team on Concerns Pertaining to Gas Transmission Lines 
Near the Indian Point Nuclear Power Plant.'' (ADAMS Accession No. 
ML20100F635) issued in April 2020 and current methodologies as 
appropriate.

III. Backfitting, Forward Fitting, and Issue Finality

    DG-1388, if finalized, would not constitute backfitting as defined 
in section 50.109 of title 10 of the Code of Federal Regulations (10 
CFR), ``Backfitting,'' and as described in NRC Management Directive 
(MD) 8.4, ``Management of Backfitting, Forward Fitting, Issue Finality, 
and Information Requests'' (ADAMS Accession No. ML18093B087); would not 
constitute forward fitting as that term is defined and described in MD 
8.4; and would not affect the issue finality of any approval issued 
under 10 CFR part 52, ``Licenses, Certificates, and Approvals for 
Nuclear Power Plants.'' As explained in DG-1388, applicants and 
licensees are not required to comply with the positions set forth in 
DG-1388.

    Dated: July 27, 2021.
