NUCLEAR REGULATORY COMMISSION

[NRC-2022-0077]


Draft Interim Staff Guidance: Advanced Reactor Content of 
Application Project Chapter 10, ``Control of Occupational Dose''

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft guidance; request for comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is soliciting 
public comment on its draft Interim Staff Guidance (ISG) DANU-ISG-2022-
04, Chapter 10, ``Control of Occupational Dose.'' The purpose of this 
proposed ISG is to provide guidance to assist the NRC staff in 
determining whether an application for a non-light water reactor (non-
LWR) design that uses the Licensing Modernization Project (LMP) process 
meets the minimum requirements for construction permits, operating 
licenses, manufacturing licenses, standard design approval, or design 
certifications.

DATES: Submit comments by July 10, 2023. Comments received after this 
date will be considered if it is practical to do so, but the Commission 
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.

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 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 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).
    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

[[Page 33938]]

can be found in the ``Availability of Documents'' section of this FRN.

III. Request for Comment

    The ARCAP draft ISG titled, ``Chapter 10, `Control of Occupational 
Dose,' '' 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 control of occupational doses is directly 
applicable only to light water reactors and 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 such an application. The Chapter 10 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 control 
of occupational dose.

V. Backfitting, Forward Fitting, and Issue Finality

    DANU-ISG-2022-04, 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-2022-04, applicants and licensees 
would not be required to comply with the positions set forth in DANU-
ISG-2022-04.

    Dated: May 22, 2023.
