NUCLEAR REGULATORY COMMISSION

[NRC-2017-0183]


Nuclear Criticality Safety Standards for Nuclear Materials 
Outside Reactor Cores

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), DG-3053, ``Nuclear 
Criticality Safety Standards for Nuclear Materials Outside Reactor 
Cores.'' This DG would be published as Revision 3 to Regulatory Guide 
(RG) 3.71. The proposed revision would provide methods that are 
acceptable to the NRC staff for criticality safety standards used with 
nuclear materials outside reactor cores. The revision would provide up-
to-date guidance based on changes to American National Standards 
Institute/American Nuclear Society (ANSI/ANS)-8 standards. The revision 
would also endorse International Organization for Standardization (ISO) 
Standard 7753:1987, ``Nuclear Energy--Performance and Testing 
Requirements for Criticality Detection and Alarm Systems.''

DATES: Submit comments by October 23, 2017. 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.

    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 posts all comment submissions at http://www.regulations.gov as well as enters 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 submissions 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.
    The DG, entitled ``Nuclear Criticality Safety Standards for Nuclear 
Materials Outside Reactor Cores,'' is a proposed revision temporarily 
identified by its task number, DG-3053. The DG-3053 is proposed 
Revision 3 of RG 3.71, ``Nuclear Criticality Safety Standards for 
Nuclear Materials outside Reactor Cores.'' The NRC initially issued RG 
3.71 in 1998, and it was revised in 2005 and again in 2010. The three 
previous versions of RG 3.71 endorsed specific safety standards 
developed by ANSI/ANS-8 to provide guidance, criteria, and best 
practices for use in preventing and mitigating criticality accidents 
during operations that involve handling, processing, storing, or 
transporting special nuclear material at fuel and material facilities 
(or a combination of these activities). The proposed Revision 3 would 
revise the RG based on changes to ANSI/ANS-8 standards, with certain 
exceptions and clarifications. The revision would also consolidate and 
replace a number of earlier NRC RGs, thereby incorporating all of the 
relevant guidance in a single document. This revision would also 
endorse International Organization for Standardization (ISO) Standard 
7753:1987, ``Nuclear Energy--Performance and Testing Requirements for 
Criticality Detection and Alarm Systems.'' In addition, the scope of 
this revision is expanded beyond part 70 of title 10 of the Code of 
Federal Regulations (10 CFR), fuel facilities to include transportation 
and storage facilities under parts 71 and 72.

III. Backfitting

    This DG-3053 would update RG 3.71 based on changes to ANSI/ANS 
standards, as well as endorsing an ISO standard and expanding the scope 
of the RG to include 10 CFR part 71 and part 72 licensees. Issuance of 
DG-3053 would not constitute backfitting under 10 CFR part 70 or part 
72. As discussed in the ``Implementation'' section of this DG, the NRC 
has no current intention to impose the DG on current holders of 10 CFR 
part 70 or part 72 licenses. The DG could be applied to applications 
for licenses issued under 10 CFR part 70 or part 72 or amendments 
thereto. Such action would not constitute backfitting as defined in 10 
CFR 70.76 or 10 CFR 72.62, inasmuch as such applicants are not within 
the scope of entities protected by 10 CFR 70.76 or 10 CFR 72.62.

    Dated at Rockville, Maryland, on August 18, 2017.

    For the Nuclear Regulatory Commission.

Chief, Regulatory Guidance and Generic Issues Branch, Division of 
Engineering, Office of Nuclear Regulatory Research.
