NUCLEAR REGULATORY COMMISSION
[NRC 2022-0063]
Performance-Based Containment Leak Test Program
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-1391, ``Performance-
Based Containment Leak Test Program''. This DG is proposed Revision 1
to regulatory guide (RG) 1.163 of the same name. The proposed revision
provides guidance on an acceptable performance-based leak-test program,
leakage-rate test methods, procedures, and analyses that may be used to
comply with NRC regulations.
DATES: Submit comments by December 19, 2022. 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.
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 for Docket ID NRC-2022-0063. Address

B. Submitting Comments
The NRC encourages electronic comment submission through the
Federal rulemaking website (https://www.regulations.gov). Please
include Docket ID NRC-2022-0063 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.
[[Page 69053]]
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
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 ``Performance-Based Containment Leak Test
Program,'' is temporarily identified by its task number, DG-1391 (ADAMS
Accession No. ML22006A317).
This revision of the guide (Revision 1) addresses new guidance for
implementing Option B ``Performance-Based Requirements'' of Appendix J,
``Primary Reactor Containment Leakage Testing for Water-Cooled Power
Reactors,'' of part 50 of title 10 of the Code of Federal Regulations
(10 CFR). Specifically, extending Type A test intervals up to 15 years,
extending Type C test intervals up to 75 months, and an update to ANSI/
ANS-56.8-2020 for acceptable industry standards on technical methods
and techniques for performing Types A, B, and C tests. This proposed
revised guide contains information specific for a leakage rate testing
program for both older plants and newer reactors licensed under both 10
CFR parts 50 and 52.
The staff is also issuing for public comment a draft regulatory
analysis (ADAMS Accession No. ML22007A009). The staff developed the
regulatory analysis to assess the value of revising RG 1.163 as well as
alternative courses of action.
III. Backfitting, Forward Fitting, and Issue Finality
Issuance of DG-1391, 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-1391, applicants and licensees would not
be required to comply with the positions set forth in DG-1391.
IV. 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/reading-rm/doc-collections/reg-guides/contactus.html.
Suggestions will be considered in future updates and enhancements to
the ``Regulatory Guide'' series.
