NUCLEAR REGULATORY COMMISSION
[NRC-2017-0016]
Guidance for Developing Principal Design Criteria for Non-Light
Water Reactors
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-1330, ``Guidance for
Developing Principal Design Criteria for Non-Light Water Reactors.''
This DG is a proposed new regulatory guide (RG) to provide designers,
applicants, and licensees of non-light water cooled nuclear reactors
(non-LWR) guidance for developing principal design criteria (PDC) for a
proposed facility. The PDC establish the necessary design, fabrication,
construction, testing, and performance requirements for structures,
systems, and components important to safety; that is, structures,
systems, and components that provide reasonable assurance that the
facility can be operated without undue risk to the health and safety of
the public.
DATES: Submit comments by April 4, 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.
ADDRESSES: You may submit comments by any of the following methods:
Federal Rulemaking Web site: Go to http://www.regulations.gov and search for Docket ID NRC-2017-0016. Address
questions about NRC dockets to Carol Gallagher; telephone: 301-415-
3463; email: [email protected]. For technical questions, contact
the individuals listed in the FOR FURTHER INFORMATION CONTACT section

Mail comments to: Cindy Bladey, Office of Administration,
Mail Stop: OWFN-12-H08, U.S. Nuclear Regulatory Commission, Washington,
DC 20555-0001.

A. Obtaining Information
Please refer to Docket ID NRC-2017-0016 when contacting the NRC
about the availability of information for this action. You may obtain
publicly-available information related to this action by any of the
following methods:
Federal Rulemaking Web site: Go to http://www.regulations.gov and search for Docket ID NRC-2017-0016.
NRC's Agencywide Documents Access and Management System
(ADAMS): You may obtain publicly-available documents online in the
ADAMS Public Documents collection at http://www.nrc.gov/reading-rm/adams.html. To begin the search, select ``ADAMS Public Documents'' and
then select ``Begin Web-based ADAMS Search.'' For problems with ADAMS,
please contact the NRC's Public Document Room (PDR) reference staff at

B. Submitting Comments
Please include Docket ID NRC-2017-0016 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 http://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.
The DG, entitled ``Guidance for Developing Principal Design
Criteria for Non-Light Water Reactors,'' is a proposed new RG. The
proposed new RG is temporarily identified by its task number, DG-1330.
The proposed new RG describes the NRC's proposed guidance on how the
general design criteria (GDC) in Appendix A, ``General Design Criteria
for Nuclear Power Plants,'' of title 10 of the Code of Federal
Regulations, part 50, ``Domestic Licensing of Production and
Utilization Facilities'' (10 CFR part 50) apply to non-LWR designs.
This guidance may be used by non-LWR reactor designers, applicants, and
licensees to develop PDC for non-LWR designs, as required by 10 CFR
part 50 for an application for a construction permit, and 10 CFR part
52 for an application for a design certification, combined license,
standard design approval, or manufacturing license. The DG also
describes the NRC's proposed guidance for modifying and supplementing
the GDC to develop PDC that address two specific non-LWR design
concepts: sodium-cooled fast reactors (SFRs), and modular high
temperature gas-cooled reactors (mHTGRs).
The advanced reactor design criteria (ARDC) are intended to be
technology-neutral and, therefore, could apply to any type of non-LWR
design. In July 2013, the NRC and U.S. Department of Energy (DOE)
established a joint initiative to review and address the existing GDC,
which may not directly apply to non-LWR power plant designs. During the
review it was determined that the safety objective for some of the
current GDC were not applicable to SFR and mHTGR technologies, so
entirely new design criteria were developed to address their unique
design features.
III. Backfitting and Issue Finality
The purpose of DG-1330 is to provide regulatory guidance to assist
future applicants in developing PDC for non-LWR designs. The NRC
approves the PDC, which form part of the licensing basis for the
facility. The DG, if finalized, would not constitute regulatory
requirements. For this reason, issuance of DG-1330, if finalized, would
not constitute backfitting under 10 CFR 50.109 (the ``Backfit Rule'').
Future applicants may choose to follow the guidance or utilize another
approach in developing principle design criteria for their facilities.
Applicants and potential applicants are not, with certain exceptions,
protected by either the Backfit Rule or any issue finality provisions
under 10 CFR part 52. Neither the Backfit Rule nor the issue finality
provisions under 10 CFR part 52--with certain exclusions discussed
below--were intended to apply to every NRC action which substantially
changes the expectations of current and future applicants. Therefore,
the positions in any regulatory guide, if imposed on applicants under
10 CFR 50.34(a)(3), 52.47(a)(3), 52.79(a)(4), 52.137(a)(3), or
52.157(a), would not represent backfitting or a violation of issue
finality (except as discussed below).
The exceptions to the general principle are applicable whenever a
combined license applicant references a 10 CFR part 52 license (i.e.,
an early site permit or a manufacturing license) and/or 10 CFR part 52
regulatory approval (i.e., a design certification rule or design
approval). There are no current non-LWR applicants or holders of
licenses or design certifications for non-LWR designs. Therefore,
issuance of DG-1330 in final form would not constitute a violation of
issue finality.
Dated at Rockville, Maryland, this 31st day of January, 2017.
