NUCLEAR REGULATORY COMMISSION
[NRC-2019-0113]
Guidance for a Technology-Inclusive, Risk-Informed, and
Performance-Based Methodology To Inform the Licensing Basis and Content
of Applications for Licenses, Certifications, and Approvals for Non-
Light Water Reactors
AGENCY: Nuclear Regulatory Commission.
ACTION: Regulatory guide; issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is issuing
revision 0 of regulatory guide (RG), RG 1.233, ``Guidance for a
Technology-Inclusive, Risk-Informed, and Performance-Based Methodology
to Inform the Licensing Basis and Content of Applications for Licenses,
Certifications, and Approvals for Non-Light Water Reactors.'' This RG
provides new guidance for designers, applicants, and licensees of non-
light water-cooled nuclear reactors (non-LWRs) to inform the licensing
basis and content of applications to the NRC for licenses,
certifications, or approvals. The RG provides guidance on using a
technology-inclusive, risk-informed, and performance-based methodology
to inform the licensing basis and content of applications for licenses,
certifications, and approvals for non-LWRs.
DATES: Revision 0 to RG 1.233 is available on June 9, 2020.

SUPPLEMENTARY INFORMATION:
I. Discussion
The NRC is issuing a new RG 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.
[[Page 35340]]
The RG, entitled ``Guidance for a Technology-Inclusive, Risk-
Informed, and Performance-Based Methodology to Inform the Licensing
Basis and Content of Applications for Licenses, Certifications, and
Approvals for Non-Light Water Reactors,'' endorses, with
clarifications, the principles and methodology in the Nuclear Energy
Institute (NEI) guidance document NEI 18-04, ``Risk-Informed
Performance-Based Guidance for Non-Light Water Reactor Licensing Basis
Development,'' as one acceptable method for determining the appropriate
scope and level of detail for parts of applications for licenses,
certifications, and approvals for non-LWRs. NEI 18-04 outlines an
approach for use by reactor developers to select licensing basis
events; classify structures, systems, and components; determine special
treatments and programmatic controls; and assess the adequacy of a
design in terms of providing layers of defense in depth. These actions
are fundamental to the safe design of non-LWRs. The methodology
described in NEI 18-04 and the RG also provide a general methodology
for identifying an appropriate scope and depth of information to be
provided in applications to the NRC for licenses, certifications, and
approvals for non-LWRs required under part 50 of title 10 of the Code
of Federal Regulations (10 CFR), ``Domestic Licensing of Production and
Utilization Facilities,'' and 10 CFR part 52, ``Licenses,
Certifications, and Approvals for Nuclear Power Plants.''
II. Additional Information
The NRC published a notice of the availability of DG-1353 in the
Federal Register on May 3, 2019 (84 FR 19132), for a 60-day public
comment period. The public comment period closed on July 2, 2019.
Public comments on DG-1353 and the staff responses to the public
comments are available under ADAMS under Accession No. ML20091L696.
III. Congressional Review Act
This RG is a rule as defined in the Congressional Review Act (5
U.S.C. 801-808). However, the Office of Management and Budget has not
found it to be a major rule as defined in the Congressional Review Act.
IV. Backfitting, Issue Finality, and Forward Fitting
RG 1.233 provides guidance for informing the licensing basis and
content of applications for non-LWRs. The RG does not constitute
regulatory requirements. For this reason, the issuance of RG 1.233 does
not constitute backfitting as defined in 10 CFR 50.109,
``Backfitting,'' and as described in NRC Management Directive 8.4,
``Management of Backfitting, Forward Fitting, Issue Finality, and
Information Requests;'' affect issue finality of any approval issued
under 10 CFR part 52; or constitute forward fitting as defined in
Management Directive 8.4. Future applicants may choose to follow the
guidance or utilize another approach in developing applications for
licenses, certifications, or approvals.
