Advanced Reactors Overview of ARCAP Roadmap ISG and TICAP DG White Papers ADAMS Accession No. ML21134A164
- Ensures consistency of staff
- reviews,
- Presents a well-defined base for scope and requirements of reviews.
- Makes information about regulatory matters widely available,
- Improves communication and understanding of the staff review process by interested members of the public and the nuclear power industry.
- Apply lessons learned from LWR application reviews
- Technology Inclusive
- Risk-Informed Performance-Based To ensure review readiness to regulate a new generation of advanced reactors, a key element of a flexible regulatory framework is to provide guidance for the development of content of an advanced reactor application.
NRC Staff Stakeholders Lessons Learned Advanced Reactor Content of Application (ARCAP)
Purpose Provides a roadmap for developing a tech-inclusive, risk-informed application. Leverages existing guidance or guidance that is under development.
Need for Additional Guidance Roadmap also identifies areas where additional guidance is needed (i.e.: Technical Specifications).
Streamlined Review Process ARCAP guidance document not intended to replicate NUREG-0800, Standard Review Plan for LWRs.
Previous Discussions ARCAP overview discussed at August 2020, October 2020, and February 2021 public meetings.
ARCAP
Background
Regulatory Applicability (As applicable) 10 CFR Parts 50, 52, and informs 53.
Broad Encompasses industry-led technology-inclusive content of application project (TICAP).
Identifies all Adv. Rx application topics.
Provides background and overview of expected information for each topic.
Provides endorsements, clarifications, supplements info, or points of emphasis.
Provides pointers to key guidance in support of application topic.
ARCAP Roadmap ISG - Outline
Purpose TICAP is industry-led guidance focused on describing the scope and level of detail for portions of an application consistent with the LMP.
LMP is described in NEI18-04, as endorsed by RG 1.233 Industry-led TICAP guidance only applicable to portions of first 8 SAR chapters.
Aims to minimize burden of generating and supplying non-safety significant information.
Methodology Scope is governed by the LMP-based safety case. LMP process is one approach to select licensing basis events, develop SSC categorization and ensures defense-in-depth is considered TICAP
Background
Regulatory Applicability (As applicable) 10 CFR Parts 50, 52, and informs 53
Endorses LMP-based NEI 21-xx TICAP document.
Provides additional clarifications, exceptions, points of emphasis from information described in NEI 21-xx.
Provides further information needed outside of LMP-based affirmative safety case for first 8 chapters.
Includes appendices to key guidance in support of FSAR development for first 8 chapters.

NRC ARCAP/TICAP Guidance Other Insights
ARCAP Roadmap ISG - Example 1
- Contents of application are still under discussion. List represents a draft outline Contents of an Advanced Reactor Application*
FSAR structure developed as a result of extensive stakeholder engagement.
Consists of 12 main chapters.
Provides the most safety-significant information at the forefront (ASC).
Focus on the most relevant safety information while removing unnecessary details.
Additional information/background is available for audit/inspection by NRC.
Note: SAR Chapters 1-8 addressed by TICAP. SAR Chapters 9-12 addressed by ARCAP.
Our Ch. 1-General Plant Information, site description, and overview of safety case (TICAP)
Information should provide an understanding of the overall facility (type of application, the number of plant units, a brief description of the proposed plant location, and the type of advanced reactor being proposed). The site description should provide an overview of the actual physical, environmental and demographic features of a site, and how they relate to the affirmative safety case.
Chapter 1 of NEI 21-xx (TICAP) as one acceptable method.
Supplements Key Guidance Endorses Clarifies Construction Permit Information in NEI 21-xx by including Appendix A for info outside LMP for first 8 chapters.*
Roadmap clarifies that guidance applicable to chapter 1 is described in NEI 21-xx - TICAP document.
RG 1.2xx Guidance For A Technology-inclusive Content Of Application Methodology To Inform The Licensing Basis And Content Of Applications For Licenses, Certifications, And Approvals For Advanced Reactors.
Note: CP information for all other portions of the application are described in Appendix E of the ARCAP roadmap ISG)
Our Ch. 2-Generic Analyses (TICAP)
Certain analyses are common to several licensing-basis event analyses. Information should describe the process and methods used to develop baseline information related to the probabilistic risk assessment (overview of the PRA), source-term analysis, and design-basis accidents (DBAs) analytical methods.
Chapter 2 of NEI 21-xx (TICAP) as one acceptable method.
Supplements Key Guidance Endorses Clarifies Site Information draft ISG previously released.
Staff positions on additional considerations to document information.
RG 1.2xx Guidance For A Technology-inclusive Content Of Application Methodology To Inform The Licensing Basis And Content Of Applications For Licenses, Certifications, And Approvals For Advanced Reactors.
Roadmap clarifies that guidance applicable to chapter 2 is described in NEI 21-xx - TICAP document.
Our Ch. 10 - Control of Occupational Dose Information should include facility and equipment design, radiation sources, and operational programs that are necessary to ensure that the occupational radiation protection standards set forth in 10 CFR Part 20 are met. The information should also include any commitments made by the applicant to develop the management policy and organizational structure necessary to ensure occupational radiation exposures are as low as (is) reasonably achievable (ALARA).

Ongoing Emergency Preparedness Requirements for Small Modular Reactors and Other New Technologies rulemaking.
Rule would amend the NRCs regulations to add new emergency preparedness requirements for small modular reactors, non-light-water reactors and non-power production or utilization facilities.
Rule would adopt a scalable plume exposure pathway emergency planning zone approach that is performance-based, consequence-oriented, and technology-inclusive.
Our Emergency Preparedness Plan This rulemaking would develop a dose-based, consequence-oriented framework for future SMR applicants and licensees with respect to offsite EP that would reduce the need for exemptions related to regulations associated with large LWRs.

SECY-18-0103 Supplements Key Guidance Endorses Clarifies Ongoing rulemaking.
Draft roadmap ISG released as white-paper to solicit stakeholder feedback. Further iterations expected.
Key Messages Whats Next?
Draft ISG expected to be released Fall 2021.
Some sections are primarily aligned with the Licensing Modernization Project (LMP), however:
the concepts and general information may be used to inform the review of an application submitted using other methodologies (as applicable) such as a maximum hypothetical accident, or deterministic approaches.
