SUPPLEMENTARY INFORMATION: I. Background The NRC staff anticipates the submission of advanced power-reactor applications within the next few years based on preapplication engagement initiated by several prospective applicants. Because many of these designs are non-LWRs, the NRC staff developed technology-inclusive, riskinformed, performance-based guidance to support the development and review of these non-LWR applications. The guidance will facilitate the development and review of non-LWR applications for construction permits or operating licenses under part 50 of title 10 of the Code of Federal Regulations (10 CFR), E:\FR\FM\03APN1.SGM 03APN1 23072 Federal Register / Vol. 89, No. 65 / Wednesday, April 3, 2024 / Notices ‘‘Domestic Licensing of Production and Utilization Facilities,’’ or combined licenses, manufacturing licenses, standard design approval, or design certifications under 10 CFR part 52, ‘‘Licenses, Certifications, and Approvals for Nuclear Power Plants.’’ The NRC staff notes it is developing a rule to amend 10 CFR parts 50 and 52 to align reactor licensing processes and incorporate lessons learned from new reactor licensing into the regulations (RIN 3150-Al66). This ISG may need to be updated to conform to changes to 10 CFR parts 50 and 52, if any, adopted through that rulemaking. Further, as of the date of this final ISG, the NRC staff is developing an optional performancebased, technology-inclusive regulatory framework for licensing nuclear power plants designated as 10 CFR part 53 (RIN 3150–AK31). The NRC intends to revise this guidance as a part of the ongoing rulemaking for 10 CFR part 53. To standardize the development of content of a non-LWR application, the NRC staff focused on two activities: the Advanced Reactor Content of Application Project (ARCAP) and the Technology-Inclusive Content of Application Project (TICAP). The ARCAP is an NRC-led activity that is intended to result in guidance for a complete non-LWR application for review under 10 CFR part 50 or 10 CFR part 52, and which the NRC staff would update, as appropriate, pending the issuance of the 10 CFR part 50 and 10 CFR part 52 rulemaking as previously mentioned in this notice, or if the Commission issues a final 10 CFR part 53 rule. As a result, the ARCAP is broad and encompasses several industry-led and NRC-led guidance document development activities aimed at facilitating a consistent approach to the development of application documents. The TICAP is an industry-led activity that is focused on providing guidance on the appropriate scope and depth of information related to the specific portions of the safety analysis report that describe the fundamental safety functions of the design and document the safety analysis of the facility using the LMP-based approach. The LMPbased approach is described in Regulatory Guide (RG) 1.233, ‘‘Guidance for a Technology-Inclusive, RiskInformed, and Performance-Based Methodology to Inform the Licensing Basis and Content of Applications for Licenses, Certifications, and Approvals for Non-Light-Water Reactors,’’ (ADAMS Accession No. ML20091L698). II. Discussion The ARCAP ISG titled, ‘‘Review of Risk-Informed, Technology-Inclusive Advanced Reactor Applications— Roadmap’’ (ARCAP Roadmap ISG), that is the subject of this Federal Register notice (FRN), was developed to provide a general overview of the information that should be included in a non-LWR application. The ARCAP Roadmap ISG also provides a review roadmap for the NRC staff with the principal purpose of ensuring consistency, quality, and uniformity of NRC staff reviews. The ARCAP Roadmap ISG includes references to eight other ARCAP ISGs and a TICAP RG that are the subject of separate FRNs notifying the public of the issuance of these guidance documents. Information regarding the eight other ARCAP ISGs and the TICAP RG can be found in the table at the end of this section.

SUPPLEMENTARY INFORMATION:

I. Background

    The NRC staff anticipates the submission of advanced power-reactor 
applications within the next few years based on preapplication 
engagement initiated by several prospective applicants. Because many of 
these designs are non-LWRs, the NRC staff developed technology-
inclusive, risk-informed, performance-based guidance to support the 
development and review of these non-LWR applications. The guidance will 
facilitate the development and review of non-LWR applications for 
construction permits or operating licenses under part 50 of title 10 of 
the Code of Federal Regulations (10 CFR),

[[Page 23072]]

``Domestic Licensing of Production and Utilization Facilities,'' or 
combined licenses, manufacturing licenses, standard design approval, or 
design certifications under 10 CFR part 52, ``Licenses, Certifications, 
and Approvals for Nuclear Power Plants.'' The NRC staff notes it is 
developing a rule to amend 10 CFR parts 50 and 52 to align reactor 
licensing processes and incorporate lessons learned from new reactor 
licensing into the regulations (RIN 3150-Al66). This ISG may need to be 
updated to conform to changes to 10 CFR parts 50 and 52, if any, 
adopted through that rulemaking. Further, as of the date of this final 
ISG, the NRC staff is developing an optional performance-based, 
technology-inclusive regulatory framework for licensing nuclear power 
plants designated as 10 CFR part 53 (RIN 3150-AK31). The NRC intends to 
revise this guidance as a part of the ongoing rulemaking for 10 CFR 
part 53.
    To standardize the development of content of a non-LWR application, 
the NRC staff focused on two activities: the Advanced Reactor Content 
of Application Project (ARCAP) and the Technology-Inclusive Content of 
Application Project (TICAP). The ARCAP is an NRC-led activity that is 
intended to result in guidance for a complete non-LWR application for 
review under 10 CFR part 50 or 10 CFR part 52, and which the NRC staff 
would update, as appropriate, pending the issuance of the 10 CFR part 
50 and 10 CFR part 52 rulemaking as previously mentioned in this 
notice, or if the Commission issues a final 10 CFR part 53 rule. As a 
result, the ARCAP is broad and encompasses several industry-led and 
NRC-led guidance document development activities aimed at facilitating 
a consistent approach to the development of application documents.
    The TICAP is an industry-led activity that is focused on providing 
guidance on the appropriate scope and depth of information related to 
the specific portions of the safety analysis report that describe the 
fundamental safety functions of the design and document the safety 
analysis of the facility using the LMP-based approach. The LMP-based 
approach is described in Regulatory Guide (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,'' (ADAMS 
Accession No. ML20091L698).

II. Discussion

    The ARCAP ISG titled, ``Review of Risk-Informed, Technology-
Inclusive Advanced Reactor Applications--Roadmap'' (ARCAP Roadmap ISG), 
that is the subject of this Federal Register notice (FRN), was 
developed to provide a general overview of the information that should 
be included in a non-LWR application. The ARCAP Roadmap ISG also 
provides a review roadmap for the NRC staff with the principal purpose 
of ensuring consistency, quality, and uniformity of NRC staff reviews. 
The ARCAP Roadmap ISG includes references to eight other ARCAP ISGs and 
a TICAP RG that are the subject of separate FRNs notifying the public 
of the issuance of these guidance documents. Information regarding the 
eight other ARCAP ISGs and the TICAP RG can be found in the table at 
the end of this section.
    The table in this notice provides the document description, ADAMS 
accession number, and, if appropriate, the docket identification 
number.

III. Additional Information

    During the 711th meeting of the Advisory Committee on Reactor 
Safeguards (ACRS), December 6-7, 2023, the ACRS, the NRC staff, and 
representatives of other stakeholders discussed guidance documents 
related to the ARCAP and the TICAP. On December 20, 2023, the ACRS 
issued a report documenting its review of these guidance documents 
(ADAMS Accession No. ML23348A182). The conclusions and recommendations 
in the ACRS report apply to all the ARCAP and TICAP guidance documents. 
In its December 2023 report, the ACRS also recommended specific changes 
to DANU-ISG-2022-01. As set forth in its letter dated March 18, 2024 
(ADAMS Accession No. ML24024A025) in which the NRC staff responded to 
the ACRS report, the NRC staff revised DANU-

[[Page 23073]]

ISG-2022-01 to address specific ACRS recommendations.
    Draft DANU-ISG-2022-01, ``Review of Risk-Informed, Technology-
Inclusive Advanced Reactor Applications--Roadmap,'' was published in 
the Federal Register for public comment on May 25, 2023, (88 FR 33924) 
with a 45-day comment period. Subsequently, the comment period was 
extended by 30 days as noted in the Federal Register dated June 28, 
2023 (88 FR 41988). The NRC staff received sixty-eight public comments 
from stakeholders. The NRC staff's evaluation and resolution of the 
public comments can be found in a document located in ADAMS under 
Accession No. ML23277A148.

IV. Congressional Review Act

    DANU-ISG-2022-01, ``Review of Risk-Informed, Technology-Inclusive 
Advanced Reactor Applications--Roadmap,'' 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.

V. Backfitting, Forward Fitting, and Issue Finality

    DANU-ISG-2022-01 does not constitute backfitting as defined in 10 
CFR 50.109, ``Backfitting,'' and as described in Management Directive 
(MD) 8.4, ``Management of Backfitting, Forward Fitting, Issue Finality, 
and Information Requests''; does not constitute forward fitting as that 
term is defined and described in MD 8.4; and does not affect the issue 
finality of any approval issued under 10 CFR part 52. The guidance 
would not apply to any current licensees or applicants or existing or 
requested approvals under 10 CFR part 52, and therefore its issuance 
cannot be a backfit or forward fit or affect issue finality. Further, 
as explained in DANU-ISG-2022-01, applicants and licensees would not be 
required to comply with the positions set forth in DANU-ISG-2022-01.

    Dated: March 28, 2024.
