II. Background The NRC 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 is developing technologyinclusive, risk-informed, performancebased guidance to support the development and review of these nonLWR applications. The proposed guidance will facilitate the development and review of non-LWR reactor applications for construction permits or operating licenses under part 50 of title 10 of the Code of Federal Regulations (10 CFR), ‘‘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 is developing a rule to amend 10 CFR parts 50 and 52 (RIN 3150– Al66). The NRC staff notes this proposed 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 draft ISG, the NRC is developing an optional performance-based, technology-inclusive regulatory framework for licensing nuclear power plants designated as 10 CFR part 53, PO 00000 Frm 00080 Fmt 4703 Sfmt 4703 33939 ‘‘Licensing and Regulation of Advanced Nuclear Reactors,’’ (RIN 3150–AK31). The NRC intends to revise this proposed 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 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 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 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 NonLight-Water Reactors,’’ (ADAMS Accession No. ML20091L698). The ARCAP draft ISG titled ‘‘Review of Risk-Informed, Technology Inclusive Advanced Reactor Applications— Roadmap’’ (ARCAP Roadmap ISG) provides 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 draft ISGs and a TICAP draft regulatory guide (DG) that are the subject of separate Federal Register notices (FRNs) requesting comment on these guidance documents. Information regarding the eight other ARCAP draft ISGs and the TICAP DG can be found in the ‘‘Availability of Documents’’ section of this FRN.

to the public or entering the comment into ADAMS.

II. Background

    The NRC 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 is developing technology-inclusive, 
risk-informed, performance-based guidance to support the development 
and review of these non-LWR applications. The proposed guidance will 
facilitate the development and review of non-LWR reactor applications 
for construction permits or operating licenses under part 50 of title 
10 of the Code of Federal Regulations (10 CFR), ``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 is developing a rule to 
amend 10 CFR parts 50 and 52 (RIN 3150-Al66). The NRC staff notes this 
proposed 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 draft ISG, the NRC is developing an optional 
performance-based, technology-inclusive regulatory framework for 
licensing nuclear power plants designated as 10 CFR part 53, 
``Licensing and Regulation of Advanced Nuclear Reactors,'' (RIN 3150-
AK31). The NRC intends to revise this proposed 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 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 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 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).
    The ARCAP draft ISG titled ``Review of Risk-Informed, Technology 
Inclusive Advanced Reactor Applications--Roadmap'' (ARCAP Roadmap ISG) 
provides 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 draft ISGs and a 
TICAP draft regulatory guide (DG) that are the subject of separate 
Federal Register notices (FRNs) requesting comment on these guidance 
documents. Information regarding the eight other ARCAP draft ISGs and 
the TICAP DG can be found in the ``Availability of Documents'' section 
of this FRN.

[[Page 33940]]

III. Request for Comment

    The ARCAP draft ISG titled, ``Risk-informed Inservice Inspection/
Inservice Testing [ISI/IST],'' that is the subject of this FRN for 
which the staff is seeking comment, was developed because the current 
application and review guidance related to ISI and IST programs are 
based on requirements found in 10 CFR 50.55a, ``Codes and standards,'' 
that are only applicable to, and focus on, large light water reactor 
(LWR) technologies. In addition, the current application and review 
guidance for large LWR ISI and IST programs may not fully (or 
efficiently) identify the information to be included in a technology-
inclusive, risk-informed, and performance-based application or provide 
a review approach for an application using non-LWR technologies. The 
Risk-informed ISI/IST draft ISG also refers to several NRC-issued, 
approved, or endorsed documents and the NRC is requesting comment on 
this proposed ISG's use of those documents.
    Additionally, the staff is issuing for public comment a draft 
regulatory analysis. The staff developed a regulatory analysis to 
assess the value of issuing or revising a regulatory guide as well as 
alternative courses of action. The development of both application 
guidance and staff review guidance is warranted. If finalized, this ISG 
will serve as the non-LWR application and review guidance for risk-
informed ISI and IST programs.

V. Backfitting, Forward Fitting, and Issue Finality

    DANU-ISG-2022-07, if finalized, would 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''; 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. 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-2022-07, applicants and licensees 
would not be required to comply with the positions set forth in DANU-
ISG-2022-07.

    Dated: May 22, 2023.

    For the Nuclear Regulatory Commission.
Steven T. Lynch,
Chief, Advanced Reactor Policy Branch, Division of Advanced Reactors 
and Non-Power Production and Utilization Facilities, Office of Nuclear 
Reactor Regulation.
